Answer:

The volume of 65 kg of the substance is 13 liters.

Step-by-step explanation:

If a substance's mass varies directly from its volume, it means that the ratio of mass to volume remains constant. In this case, we can calculate the continuous ratio and then use it to find the volume.

Given:

Mass1 = 30 kg

Volume1 = 6 liters

Let's denote the constant ratio as k.

Mass1 / Volume1 = k

30 kg / 6 liters = k

k = 5 kg/liter

Now, we can find the volume2 for a mass of 65 kg using the constant ratio:

Mass2 = 65 kg

Volume2 = ?

Mass2 / Volume2 = k

65 kg / Volume2 = 5 kg/liter

To find Volume2, we can cross multiply:

65 kg = 5 kg/liter * Volume2

Volume2 = 65 kg / 5 kg/liter

Volume2 = 13 liters

Answer:

90° and 90°.

Step-by-step explanation:

The only combination of 2 angles that sum to 180° with each not being less than 90° is 2 90° themselves! Technically, 90 is indeed not less than 90. It is not possible to find any other combinations because if one angle is made bigger, the other will be forced to become smaller, and if any angle becomes any smaller it will, of course, be less than 90° and thus not a solution to the problem.

Answer:

  1a) x = 4

  1c) x = 6

  1d) x = 10

  1f) x = -42

Step-by-step explanation:

1a) 3x -8 = 4

This is a "two step" equation with a variable term and constant on the same side of the equal sign. Step 1, add the opposite of that constant to both sides of the equation:

  3x = 12

Step 2: divide both sides of the equation by the coefficient of the variable:

  x = 4

__

1c) This is similar to 1a, except that it has variables on both sides of the equal sign. Find the variable term with the smallest coefficient. Here, it is -x, because the coefficient -1 is less than 2. Add the opposite of that term to both sides of the equation:

  3x -8 = 10

Now, you have a 2-step equation in the same form as 1a. Solve it the same way.

  3x = 18 . . . . add 8

  x = 6 . . . . . . divide by 3

Check

  2(6) -8 = 10 -(6)

  12 -8 = 10 -6

  4 = 4 . . . . . true; answer is correct

__

1d) After you eliminate parentheses using the distributive property, you end up with a 3-step equation as in 1c.

  6x -12 = 3x +2x -2

  6x -12 = 5x -2 . . . . . . combine like terms. (5x is the smallest x-term)

  x -12 = -2 . . . . . . . . . subtract 5x

  x = 10 . . . . . . . . . . . . add 12

Check

  6(10 -2) = 3(10) +2(10 -1)

  6(8) = 30 +2(9)

  48 = 30 +18

  48 = 48 . . . . true; answer is correct

__

1f) You can work this as is using the fractional coefficients. Most folks prefer to "clear fractions" first. To do that, you need to find the least common denominator and multiply both sides of the equation by it. The least common denominator of 1/3 and 1/2 is 6.

  2x = 3x +42 . . . . . multiply both sides by 6

  0 = x + 42 . . . . . . . subtract the smallest x-term from both sides

  -42 = x . . . . . . . . . add -42

Check

  (-42)/3 = (-42)/2 +7

  -14 = -21 +7

  -14 = -14 . . . . . . . true; answer is correct

___

If you work this using the given coefficients, you can subtract 1/3x to get ...

  0 = x/6 +7

  -7 = x/6 . . . . . subtract 7

  -42 = x . . . . . . multiply by 6

You notice that we had to multiply by 6 in the solution process anyway. Doing that first makes the fractions go away, so is often the preferred solution method.

Answer:

Number 7 (I DONT KNOW THE OTHER ONES)

Step-by-step explanation:

Answer:

There are 19 quarters and 8 dimes.

Step-by-step explanation:

We will let x denote the amount of quarters.

Since there are 27 coins in total, (27-x) will be the amount of dimes there are.

Since each quarter is worth $0.25, the total value of quarters is given by 0.25x.

And since each dime is worth $0.10, the total value of dimes is given by 0.1(27-x).

We know that the total value of all 27 coins is $5.55. So, we can write the following equation:

So, we will determine the value of x, the amount of quarters there are.  

First, let’s multiply everything by 100 to remove the decimals. So:

(Distribute)

(Distribute)

(Combine like terms)

(Subtract 270 from both sides)

(Divide both sides by 15)

So, the value of x is 19.

This means that there are 19 quarters.

So, the amount of dimes must be 27-19 or 8 dimes.

Step-by-step explanation:

Value of t0 for option a is ±1.895 and for option, b is 1.895 using symmetric and complement properties respectively.

Given  that t follows a t7 distribution let's understand what is t7 distribution

The t distribution (Student's t-distribution) is a "probability distribution used to estimate population parameters when the sample size is small (n<30) or the population variance is unknown".

The t-distribution describes a set of observations in which the majority of observations fall close to the mean and the remainder of the observations form the tails on either side. It is a type of normal distribution that is used for smaller sample sizes when the data variance is unknown.

The degrees of freedom of the t distribution determine its shape, and as the degrees of freedom increase, the t distribution approximates a normal distribution.

The degrees of freedom stand for "the number of distinct observations in a set of data. If we estimate a mean score from a single sample, for example, the number of independent observations is equal to the sample size minus one."

P(|t|<\(t_{0}\)) = 0.9

We can rewrite the expression using absolute value properties as follows:

P(-\(t_{0}\)<\(t_{7}\)<\(t_{0}\)) = 0.9

Using symmetric property we can write

1-2P(t7 < -t0) = 0.9

0.1 = 2P(t7 < -t0)

P(t7 < -t0) = 0.05

And we can find the value by typing "=T.INV(0.05,7)" into Excel.

So, in this case, the answer is t0 = ±1.895

for part B we have p(t>t0) = 0.05 for this we have to use complement rule

1- p(t7<t0) = 0.05

p(t7<t0) = 1 - 0.05  

p(t7<t0) = 0.95

And we can find the value by typing "=T.INV(0.95,7)" into Excel.

So, in this case, the answer is t0 = 1.895

Given that |f(z)| ≤ C|z|^2 for all |z| ≥ R, where f(z) is an entire function, we aim to prove that f(z) is a polynomial with degree at most 2. To do this, we will use Cauchy estimates and show that the third derivative

Let's consider the third derivative of f(z), denoted as f'''(z). Using Cauchy estimates, we have:

|f'''(z_0)| ≤ (3!)/R^3 * sup|f(z)| on |z - z_0| = R,

where z_0 is any complex number. From the given property |f(z)| ≤ C|z|^2, we can substitute this inequality into the above estimate:

|f'''(z_0)| ≤ 6C/R^3 * R^2 = 6C/R.

Since C and R are positive constants, the right-hand side of the inequality tends to zero as R goes to infinity. Therefore, f'''(z_0) must be zero for all z_0 in the complex plane.

From this, we conclude that f(z) is a polynomial of degree at most 2. If f'''(z) is identically zero, it means that f(z) has no terms of degree higher than 2, and hence, it is a polynomial with degree at most 2.

Therefore, we have proved that if |f(z)| ≤ C|z|^2 for all |z| ≥ R, then f(z) is a polynomial with degree at most 2.

the acosta family went out to dinner. the price of the meal was $79.85. if the tip was 15%.The Acosta family paid $91.83 for the meal, including the 15% tip.

To calculate the total amount paid, we need to add the original price of the meal to the tip amount. The price of the meal was $79.85, and the tip was 15% of that amount. To find the tip, we multiply $79.85 by 0.15 (or 15% expressed as a decimal), which equals $11.98. Adding the tip of $11.98 to the original price, the total amount paid is $91.83.

In more detail, a 15% tip means that 15% of the meal price is added as an extra amount to the bill. To calculate the tip, we multiply the meal price ($79.85) by 0.15 (or 15% as a decimal), resulting in $11.98. This represents the additional amount the Acosta family paid for the tip. To find the total amount paid, we add the tip amount to the original meal price: $79.85 + $11.98 = $91.83. Therefore, the Acosta family paid $91.83 for the meal, including the tip.

To determine whether the series is converging or diverging, additional tests may be required, such as the Comparison Test or the Limit Comparison Test.

To test the series for convergence or divergence:

\(\Sigma_{n=1}^{\infty} \frac{n^{2n}}{(1+n)^{3n}}\)

The Ratio Test can be used to assess if the series is converging or diverging. According to the ratio test, a series converges if the absolute limit of the ratio between two consecutive terms is less than 1. The series diverges if the limit is higher than 1. The test is not convincing if the limit is equal to 1.

Let's use our series to illustrate the Ratio Test:

\(lim_{n\rightarrow \infty} |\frac{(n+1)^{2(n+1)}}{(1+(n+1)^{3(n+1)}} \times \frac{(1+n)^{3n}}{ n^{2n}}|\)

Simplifying the expression:

\(lim_{n\rightarrow\infty} \left|\left(\frac{n+1}{n}\right)^{2(n+1) - 3n} \times \frac{((1+n) / (1+n))^{3n}}{(1+n)^{3(n+1) - 2n}}\right|\)

\(lim_{n\rightarrow\infty} \left|\left(\frac{n+1}{n}\right)^{-n + 2} \times \frac{(1+n)^{3n}}{ (1+n)^{n+3}}\right|\)

\(lim_{n\rightarrow\infty} |\left(\frac{n+1}{n}\right)^{-n + 2} \times (1+n)^{3n - (n+3)}|\)

\(lim_{n\rightarrow\infty} \left|\left(\frac{n+1}{n}\right)^{-n + 2} \times (1+n)^{2n - 3}\right|\)

As n approaches infinity, the limit of \(\left|\frac{n+1}{n}\right|\) is 1.

Therefore, the limit simplifies to:

\(lim_{n\rightarrow\infty} |(1+n)^{2n - 3}|\)

The limit is positive because for n 1, the exponent 2n - 3 is always positive.

As a result, 1 is the absolute limit of the ratio of successive words.

The Ratio Test states that the test is inconclusive when the limit equals 1, and we cannot tell whether the series converges or diverges based solely on this test.

To ascertain if the series is converging or diverging, further tests, such as the Comparison Test or the Integral Test, may be necessary.

If negative sixteen plus the quotient of a number and 2 is 35, the number is 102.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number = x

Negative sixteen plus the quotient of a number and 2 is 35.

This can be written as,

Quotient of a number and 2.

x ÷ 2 = M (quotient)

So,

-16 + M = 35

Now,

Solve for M.

M = 35 + 16

M = 51

Now,

x ÷ 2 = 51

x/2 = 51

x = 51 x 2

x = 102

Now,

We can cross-check.

-16 + 51 = 35

35 = 35

\(Pr = \frac{1}{45}\)

Step-by-step explanation:

Given

\(Black =5\)

\(Pink = 2\)

\(Blue = 3\)

Required

\(P(Pink\ and\ Pink)\)

This is calculated as:

\(Pr = P(Pink) * P(Pink)\)

Because it is a selection without replacement, the probability is:

\(Pr = \frac{n(Pink)}{Total} * \frac{n(Pink) - 1}{Total - 1}\)

\(Pr = \frac{2}{10} * \frac{2 - 1}{10 - 1}\)

\(Pr = \frac{2}{10} * \frac{1}{9}\)

\(Pr = \frac{1}{5} * \frac{1}{9}\)

The probability of getting at least one head in two flips of a coin is 3/4 or 0.75, which means that there is a 75% chance of getting at least one head in two flips of a coin.

To find the probability of at least one head in two flips of a coin, we can use the complement rule. The complement of the event "at least one head" is "no heads."

The probability of getting no heads in two flips of a coin is (1/2) x (1/2) = 1/4.

Therefore, the probability of getting at least one head in two flips of a coin is:

1 - (probability of no heads) = 1 - 1/4 = 3/4

The probability of getting at least one head in two flips of a coin is 3/4 or 0.75, which means that there is a 75% chance of getting at least one head in two flips of a coin.

In other words, if you flip a coin twice, the probability of getting at least one head is relatively high, and you are more likely to get at least one head than to get no heads at all.
