The number of hours that Maria practiced in the past 2 weeks will be 4 1/4 hours.

From the information, Maria practiced the piano for 2 1/2 hours last week and 1 3/4 hours this week.

Therefore, the number of hours that Maria practiced in the past 2 weeks will be:

= 2 1/2 + 1 3/4

= 2 2/4 + 1 3/4

= 4 1/4 hours

The number of hours that Maria practiced in the past 2 weeks will be 4 1/4 hours.

It should be noted that the z-score to the nearest tenth, is z ≈ 1.1. Therefore, the correct answer is: 1.1; not unusual.

In order to find the z-score corresponding to a given value, we can use the formula:

z = (x - μ) / σ

where:

x is the given value (time for the 100 meter sprint)

μ is the mean time for the 100 meter sprint

σ is the standard deviation

Let's calculate the z-score for the time of 19.8 seconds:

z = (19.8 - 17.5) / 2.1

z ≈ 1.1

Rounding the z-score to the nearest tenth, we have z ≈ 1.1.

Since the z-score of 1.1 is not less than -2.00 or greater than 2.00, we can conclude that the time of 19.8 seconds is not unusual based on the given criteria.

Therefore, the correct answer is: 1.1; not unusual.

Step-by-step explanation:

3x5=15 one remainder

Answer: The sum of two numbers is 7. Three times one of the numbers is 15 more than the other number. Find the numbers.

Let X and Y be the two numbers.

X + Y = 7 "The sum of two numbers is 7."

3X = Y + 15 "Three times one of the numbers is 15 more than the other number."

Taking the TOP EQUATION and solving for X:

X + Y = 7

X = 7 - Y Subtracting Y from both sides of the equation.

Plugging 7 - Y into the BOTTOM EQUATION for X:

3X = Y + 15

3(7 - Y) = Y + 15

21 - 3Y = Y + 15 Distribute 3 times (7 - Y)

-3Y = Y + 15 - 21 Subtracting 21 from both sides of the equation.

-3Y = Y - 6 15 - 21 = -6

-4Y = - 6 Subtracting Y from both sides of the equation.

Y = - 6/ - 4 Dividing both sides of the equation by - 4.

Y = 3/2 or 1.5

Plugging 3/2 into the TOP EQUATION for Y to solve for X:

X + Y = 7

X + 3/2 = 7

X = 7 - 3/2 Subtracting 3/2 from both sides of the equation.

X = 14/2 - 3/2 = 11/2 = 5.5

ANSWER: ONE NUMBER IS 1.5 AND THE OTHER NUMBER IS 5.5

CHECKING:

TOP EQUATION: X + Y = 7

5.5 + 1.5 = 7 Yes!

BOTTOM EQUATION: 3X = Y + 15

3(5.5) = 1.5 + 15

16.5 = 16.5 Yes!

Answer:Can somebody also help me with this. i'm confused please hurry!

Step-by-step explanation:

These are indeed equivalent, and this identity is one of DeMorgan's laws.

The 6th column is the negation of the 5th column. For example, the first row says

not p or q

is true (T), so the negation would be false (F). The 5th column reads {T, F, T, T}, so the next column should be {F, T, F, F}.

Then in the 7th/last column, you are checking the truth value of the statement

p and not q

For example, in the first row, both p and q are true (T). This means (not q) is false, so (p and not q) is false (F). The last column should end up reading {F, T, F, F}, same as the previous column.

Step-by-step explanation:

it seems you solved the tricky part yourself already.

just to be sure, let's do the first derivative here again.

the easiest way would be for me to simply multiply the functional expression out and then do a simple derivative action ...

f(t) = (t² + 6t + 7)(3t² + 3) = 3t⁴ + 3t² + 18t³ + 18t + 21t² + 21 =

= 3t⁴ + 18t³ + 24t² + 18t + 21

f'(t) = 12t³ + 54t² + 48t + 18

and now comes the simple part (what was your problem here, don't you know how functions work ? then you are in a completely wrong class doing derivatives; for that you need to understand what functions are, and how they work). we calculate the function result of f'(2).

we simply put the input number (2) at every place of the input variable (t).

so,

f'(2) = 12×2³ + 54×2² + 48×2 + 18 = 96 + 216 + 96 + 18 =

The GPA of a student who studies for 15 hours a week is 3.125 GPA.

In Mathematics, the standard form of the equation of a regression line is represented or modeled by the following mathematical expression;

y = bx + c

Where:

Since the student would study for 15 hours a week, the predicted GPA can be calculated as follows;

y = 0.149x + 0.89

y = 0.149(15) + 0.89

y = 3.125 GPA.

The rental car is getting approximately 37.56 miles per gallon.

To convert kilometers per liter (km/l) to miles per gallon (mpg), you can use the following conversion factor:

1 km/l ≈ 2.82475 mpg

Therefore, if your rental car is getting 13.3 km/l of gasoline, the equivalent value in miles per gallon would be:

13.3 km/l x 2.82475 mpg ≈ 37.56 mpg

So, your rental car is getting approximately 37.56 miles per gallon.

Answer:

To simplify the expression (a÷b)³×(b÷c)×(c÷a)³ when a=3, b=a², c=a³, we can substitute the given values and perform the calculations.

Substituting the values of a, b, and c:

a = 3

b = a² = 3² = 9

c = a³ = 3³ = 27

Now let's simplify the expression:

(a÷b)³×(b÷c)×(c÷a)³

(3÷9)³×(9÷27)×(27÷3)³

Simplifying each term:

(3÷9) = 1/3

(9÷27) = 1/3

(27÷3) = 9

Now we can substitute the simplified values back into the expression:

(1/3)³×(1/3)×9

Simplifying further:

(1/27)×(1/3)×9

1/9

Therefore, the simplified expression is 1/9.

Answer:

the actual hourly percent increase is 6.823 %

Step-by-step explanation:

Given that data in the question;

rate chemical decomposes increasing continuously at 6.6 %,

r = 6.6% = 0.066

actual hourly percent increase = ?

Now,

hourly percent increase = ( \(e^r\) - 1 ) × 100%

we substitute

hourly percent increase = ( \(e^{0.066\) - 1 ) × 100%

hourly percent increase = ( 1.06823 - 1 ) × 100%

hourly percent increase = 0.06823 × 100%

hourly percent increase = 6.823 %

Therefore, the actual hourly percent increase is 6.823 %

Answer:

Regular hourly rate for Brandon is $30

Step-by-step explanation:

Let the payment for regular hours be $x

given that

Brandon is paid 150% of his regular hourly rate for overtime hours

payment for overtime hours = 150% of payment for regular hours

payment for overtime hours = 150/100 * x = 3x/2

Given that He is paid \$45.00 an hour for overtime hours

thus,

3x/2 = 45

=> x = 45*2/3 = 30

Thus,  regular hourly rate for Brandon is $30

The solutions to the quadratic equation 6x² = -3x + 1 to the nearest hundredth are -0.73 and 0.23.

Given the quadratic equation in the question:

6x² = -3x + 1

To solve the quadratic equation 6x² = -3x + 1, we can rearrange it into standard form, where one side is set to zero:

6x² + 3x - 1 = 0

Now we can solve the equation using the quadratic formula, which states that for an equation in the form ax² + bx + c = 0, the solutions for x are given by:

\(x = \frac{-b \±\sqrt{b^2-4ac} }{2a}\)

Here; a = 6, b = 3, and c = -1.

Let's substitute these values into the quadratic formula:

\(x = \frac{-b \±\sqrt{b^2-4ac} }{2a}\\\\ x= \frac{-3 \±\sqrt{3^2-4\ *\ 6\ *\ -1} }{2*6}\\\\x = \frac{-3 \±\sqrt{9+24} }{12}\\\\x = \frac{-3 \±\sqrt{33} }{12}\\\\x = -0.73, \ x=0.23\)

Therefore, the values of x are -0.73 and 0.23.

A physical quantity that has both directions and magnitude is referred to as a vector quantity.

A lowercase letter with a "hat" circumflex, such as "û," is used to denote a vector with a magnitude equal to one. This type of vector is known as a unit vector.

To evaluate u + v - 4u, we first need to find the vector 4u, which is obtained by multiplying the vector u by the scalar 4:

4u = 4(5,-2) = (20,-8)

Now, we can add u and v, and subtract 4u from the result:

u + v - 4u = (5,-2) + (-5,7) - (20,-8)

= (5 - 5 - 20, -2 + 7 + 8)

= (-20, 13)

Therefore, u + v - 4u = (-20, 13).
