Step-by-step explanation:

Here, we are interested in getting the median of the distribution

Mathematically, if we are talking about a moral distribution, we have equal values for median, mode and mean

Hence the median in this case will be 69

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:

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.

Answer:

Step-by-step explanation:

one row has 22 seats

2 rows have 44 seats

44x56.89=2,503.16

Answer:

2,507.12

Step-by-step explanation:

If we know that there is 22 two seats in each row, and we are trying to solve for two rows, multiply the numbers of seats in each row by the number of rows:

2x22=44

Now that we know how many seats we have, simply times this by the price of each seat:

44x56.89=2,507.12

Based on this math, we can see that it would cost 2,507.12 dollars to buy two full rows of seats. Hope this helps!

Answer:

18*8*10= 1440

Step-by-step explanation:

volume L*W*H

Volume 18 m * 8 m *10 m

Volume= 1440

Volume= 9 m *5 m *24 m

Volume= 1080

Answer:

[tex]y = \frac{2}{3} x[/tex]

Step-by-step explanation:

Notice how it passed through at exactly (3,2) and (6,4).

By taking the formula for slope:

[tex]m = \frac{rise}{run} = \frac{y}{x} \\ = \frac{2}{3} [/tex]

Substituting this into the slope-intercept form

y = mx + b

where m is the slope of the line and b is the y-intercept.

Since we were not given the y-intercept and the line started or passes through (0,0), we can safely assume that b = 0.

Therefore,

[tex]y = \frac{2}{3} x[/tex]

please give me brainlest❤️

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. 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.

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

4 x 2 = 8

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)

Complete question :

The sugar maple tree in Joshua's yard is 1/4 the age of the oak tree in his yard. The sugar maple tree is 20 years old. How old is the oak tree?

Answer:

80 years

Step-by-step explanation:

Given that :

Sugar maple tree = 1/4 age of oak tree

Age of sugar maple tree = 20

Age of oak tree = x

20 = 1/4 * x

20 = x / 4

Multiply both sides by 4

20 * 4 = (x / 4) * 4

80 = x

Hence, Age of oak tree = 80 years
