The equivalent expression for 4(5−3x) is ( 20 - 12x).

This states that multiplying the sum of two or more addends by a number produces the same result as multiplying each addend separately by the number and then adding the products together.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the expression is 4(5−3x). The expression by distribution property will be solved as,

E =  4(5−3x)

Multiply by 4 in the whole equation,

E = (  4 x 5 - 4 x 3x )

E = 20 - 12x

The more powerful the motor is, the greater the ability to do the work (option b).

A more powerful motor has a higher capacity to generate energy and produce output, allowing it to exert more force and perform work more efficiently. With greater power, the motor can overcome resistance or load with ease and accomplish tasks that may be challenging for less powerful motors.

On the other hand, the time interval for doing the work (option a) and the workload (option c) are not directly dependent on the motor's power. These factors are influenced by other variables such as the specific task, operational conditions, and the requirements of the work itself.

While a more powerful motor may complete a task faster due to its efficiency, the duration of the work and the workload are not determined solely by the motor's power.Therefore, option b, "the greater the ability to do the work is," accurately reflects the relationship between motor power and work capability.

The value of the second derivative, f''(4), for the function \(f(x) = (x^2/2 + x)\), is 1.

To find the value of f''(4) given the function \(f(x) = (x^2/2 + x)\), we need to take the second derivative of f(x) and then evaluate it at x = 4.

First, let's find the first derivative of f(x) with respect to x:

\(f'(x) = d/dx[(x^2/2 + x)]\)

= (1/2)(2x) + 1

= x + 1.

Next, let's find the second derivative of f(x) with respect to x:

f''(x) = d/dx[x + 1]

= 1.

Now, we can evaluate f''(4):

f''(4) = 1.

Answer: The other number is 85.

Step-by-step explanation:

We can conclude that the null hypothesis is rejected. There is sufficient evidence to support the claim that the mean cost in Utah hospitals is below the national mean of $1231.

H₀: μ ≥ 1231 (The mean cost in Utah hospitals is greater than or equal to the national mean)

Hₐ: μ < 1231 (The mean cost in Utah hospitals is below the national mean)

Given

The test statistic for a one-sample t-test is given by

t = (x - μ) / (σ / √n)

Substituting we have

t = (1103 - 1231) / (252 / √25)

≈ -6.103

To determine the critical value, we need to find the critical t-value at the 5% significance level with degrees of freedom

(df) equal to (n - 1)

= (25 - 1)

= 24.

Using a t-distribution table or calculator, the critical value is approximately -1.711.

Since the calculated test statistic (-6.103) is smaller than the critical value (-1.711) and falls into the critical region, we reject the null hypothesis.

Answer:

61

Step-by-step explanation:

Because all triangles's angles sum is always equal to 180, we can establish the equation, (9x - 31) + (7x - 2) + (4x + 33) = 180.

Simplifying, we get;

9x - 31 + 7x - 2 + 4x + 33 = 180

20x = 180

x = 9.

So, angle DCE = 7x - 2 = 7 * 9 - 2 = 63 - 2 = 61

The centroid of the region bounded by the curves y = 12x and y = √x is (72,1.88).

To find the centroid of the region bounded by the given curves y = 12x and y = √x, the following steps should be followed.

Step 1: Sketch the region bounded by the two curves to have an idea of what the region looks like.

Step 2: Determine the area of the region bounded by the two curves. The area A can be computed by evaluating the definite integral of the difference between the two functions. \(\[\int\limits_{0}^{144} (\sqrt{x}-12x)dx\]\)  We solve for this integral below.\(\[\int\limits_{0}^{144} (\sqrt{x}-12x)dx = 64 - 1728 + \frac{2}{3}\sqrt{6}\] \[\int\limits_{0}^{144} (\sqrt{x}-12x)dx = -1663.30\]\)

Step 3: To find the centroid of the region, we need to determine the x and y coordinates of the centroid. The x-coordinate of the centroid is given by the formula below.

\(\[x = \frac{1}{A}\int\limits_{a}^{b} \frac{1}{2}(y_1^2-y_2^2)dx\]\)

where A is the area of the region, and y1 and y2 are the upper and lower functions, respectively. Substituting values, we obtain

\(\[x = \frac{1}{-1663.30}\int\limits_{0}^{144} \frac{1}{2}((\sqrt{x})^2-(12x)^2)dx\]  \[x = 72\]\)

 The y-coordinate of the centroid is given by the formula below.

\(\[y = \frac{1}{2A}\int\limits_{a}^{b}(y_1+y_2)\sqrt{(y_1-y_2)^2+4dx}\]\)

 Substituting values, we obtain \(\[y = \frac{1}{2(-1663.30)}\int\limits_{0}^{144}(12x+\sqrt{x})\sqrt{(\sqrt{x}-12x)^2+4dx}\]  \[y = 1.88\]\)

Answer:

a)0.976

b)0.00926

c)0.2402

d)0.35

Step-by-step explanation:

Let \(X_i\) be an item passed by inspector i

Let Y be the event that there is a fault in an item

The probability that an item has a flaw is 0.1 i.e. P(Y)=0.1

If a flaw is present ,it will be detected by the first inspector with probability 0.92 i.e.\(P(\bar{X_1}|Y)=0.92\)

So, \(P(X_1|Y)=1-0.92=0.08\)

If a flaw is present ,it will be detected by the second inspector with probability 0.7 i.e.\(P(\bar{X_2}|Y)=0.7\)

So,\(P(X_2|Y)=1-0.7=0.3\)

If an item does not have a flaw, it will be passed by the first inspector with probability 0.95 i.e. \(P(X_1|\bar{Y}) = 0.95\)

So, \(P(\bar{X_1}|\bar{Y}) = 1-0.95=0.05\)

If an item does not have a flaw, it will be passed by the second inspector with probability 0.8 i.e. \(P(X_2|\bar{Y}) = 0.8\)

So, \(P(\bar{X_2}|\bar{Y}) = 1-0.8=0.2\)

a)P(found by atleast one inspector | It has flaw )=1-P(found by none inspector | It has flow )

P(found by atleast one inspector | It has flaw )=\(1-P(X_1|Y) P(X_2|Y)\)

P(found by atleast one inspector | It has flaw )=\(1-0.08 \times 0.3\)

P(found by atleast one inspector | It has flaw )=0.976

Hence the probability that it will be found by at least one of the two inspectors if it has flaw is 0.976

b)\(P(Y|X_1)=\frac{P(X_1|Y) P(Y)}{P(X_1|Y) P(Y)+P(X_1|\bar{Y}) P(\bar{Y})}\)

\(P(Y|X_1)=\frac{0.08 \times 0.1}{0.08 \times 0.1+0.95 \times 0.9}=0.00926\)

C)P( two inspectors draw different conclusions on the same item)=\(P(X_1 \cap \bar{X_2} \cap Y)+P(\bar{X_1} \cap X_2 \cap Y)+P(X_1 \cap \bar{X_2} \cap \bar{Y})+P(\bar{X_1} \cap X_2 \cap \bar{Y})\)

P( two inspectors draw different conclusions on the same item)=0.2402

D)

\(P(Y|(X_1 \cap X_2))=\frac{P(Y \cap X_1 \cap X_2)}{P(X_1 \cap X_2)}\\P(Y|(X_1 \cap X_2))=\frac{P(Y \cap X_1 \cap X_2)}{P(X_1 \cap X_2 \cap Y)+P(X_1 \cap X_2 \cap \bar{Y})}\\P(Y|(X_1 \cap X_2))=0.35\)

Given

y = - 8 /5 x + 2

Comparing the given equation with y = mx + c

slope (m) = - 8/5

Hope it will help :)

Answer:

-8/5

Explanation:

The equation is written in slope-intercept form, aka y = mx + b, where m is the slope and b is the y-intercept.

In slope intercept, the slope is always the number that comes before x.

In the equation y = -8/5x + 2, that number is -8/5.

Hence, the answer is -8/5.

The mean of the new distribution will be 33 after the addition of 3 points to each score.

Here, correct option will be:- b. 33

The mean of a population is a measure of central tendency that provides an average of the data within a data set. In this question, we are given the mean of a population as 30 and are asked to determine the mean of the new distribution after 3 points have been added to each score.

To answer this question, we must recognize that adding 3 points to each score in the population will increase the mean of the population by 3 points.

Therefore, the new mean of the distribution will be 33 i.e option b. This is because the addition of 3 points to each score will increase the total sum of all the scores, which will in turn increase the mean of the population.

The decimal equivalent of 1101.101 in base 9 is 729.1184.

The decimal equivalent of an unsigned base 9 value is simply the number represented in the decimal system.

To find the decimal equivalent of 1101.101 in base 9, we need to convert each digit to its decimal equivalent.

First, we'll convert the whole number portion of 1101.101.

1101 in base 9 is equivalent to

=> 9³ + 1 = 729

Now, we'll convert the fractional portion.

The first digit after the decimal point, 1, represents 1/9.

The next digit, 0, represents 0/9².

The last digit, 1, represents 1/9³.

Adding these values together, we get

=> 729 + 1/9 + 1/729 = 729.1184
