Answer:

8 cups

Step-by-step explanation

8 cups. There are 2 cups in one pint and two pints in one quart. To Get 8 cups all you do is multiple the quartz by 2 to get the amount of pints, and multiply the pints by 2 to get the number of cups. Thus the equation would be 2 * 2 = 4 and 4 * 2 = 8.

Answer:

D. 8 cups

Step-by-step explanation:

1 Quart is 4 cups therefore you multiply

Answer:595 will be approved

Step-by-step explanation:

The number of 109 of robots will be approved by the quality-control inspector.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

80.5% of 136 robots on an assembly line will be approved by the quality-control inspector.

Let n number of robots will be approved.

n = 80.5% of 136

n = 80.5 x 136 /100

n = 109.48

n ≈ 109.

Therefore, 109 robots will be approved.

Answer:

Raul's errors are in the application of the distributive property(he applied it wrongly), in not respecting the precedence of operations, and in the multiplication of two terms with the same base(we add the exponent).

Step-by-step explanation:

Distributive property:

The distributive property of multiplication is:

a*(b + c) = a*b + a*c

Precedence of operations:

First multiplication, then addition.

Multiplication of terms with the same base:

The multiplication of h*h = h², which Raul missed.

The correct simplification is given by:

[tex]-[3h + 7h(2-h)] = -[3h + 14h - 7h^2] = -[17h - 7h^2]=7h^2 - 17h[/tex]

Answer:

he should have  worked out 7h(2 - h) first before adding the 3h. (first step)

2nd step he multiplied the 2 by -10h  but he also should have multiplied the -h by the -10h ( Distributive law)

Answer:

The 95% confidence interval for the population mean is between $140.89 and $159.11.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1-0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].

So it is z with a pvalue of [tex]1-0.025 = 0.975[/tex], so [tex]z = 1.96[/tex]

Now, find the margin of error M as such

[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 1.96\frac{36}{\sqrt{150}} = 9.11[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 150 - 9.11 = $140.89

The upper end of the interval is the sample mean added to M. So it is 150 + 9.11 = $159.11

The 95% confidence interval for the population mean is between $140.89 and $159.11.

A

Step-by-step explanation:

V=lwh=4•4•2=16•2=32

Using the concepts of the mean and the median, the correct option is given by:

B.

The mean is not resistant because when data are​ skewed, there are extreme values in the​ tail, which tend to pull the mean in the direction of the tail. The median is resistant because the median of a variable is the value that lies in the middle of the data when arranged in ascending order and does not depend on the extreme values of the data.

Answer:

A sample of 11352 is needed.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

For this problem, we have that:

400 cards, 120 cases were correct. So

[tex]p = \frac{120}{400} = 0.3[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

How large a sample n would you need to estimate p with margin of error 0.01 and 95% confidence

We would need a sample of size n, and n is found when [tex]M = 0.01[/tex]. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.01 = 2.325\sqrt{\frac{0.3*0.7}{n}}[/tex]

[tex]0.01\sqrt{n} = 2.325\sqrt{0.3*0.7}[/tex]

[tex]\sqrt{n} = \frac{2.325\sqrt{0.3*0.7}}{0.01}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.325\sqrt{0.3*0.7}}{0.01})^2[/tex]

[tex]n = 11351.8[/tex]

Answer:

A. Function A has a rate of change of -5 and Function B has a rate of change of -4.5, so Function A has a greater rate of change

Step-by-step explanation:

✔️Function A rate of change can be calculated using two points, (1.5, 5) and (2.5, 0)

[tex] rate of change = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - 5}{2.5 - 1.5} = \frac{-5}{1} = -5 [/tex]

Rate of change of function A = -5

✔️Rate of change of Function B, y = -4.5x + 15:

The equation for function B is given in the slope-intercept form, y = mx + b. Here, m represents the rate of change.

Therefore, the rate of change of the equation, y = -4.5x + 15, is -4.5.

✔️Function A has a rate of change of -5 and Function B has a rate of change of -4.5, so Function A has a greater rate of change. This is because the larger the value, regardless of the sign, the steeper the slope.
