Answer:

The predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes

Step-by-step explanation:

Regression Output :

Predictor                            Coefficient

Constant                             3.0979

Square root of items          2.7633

R.sq.- 96.7%

So, with this data the regression equation is,

\(\hat{y}=3.0979+2.7633x\)

Now we are supposed to find the predicted time, in minutes, that it took to gather the items if the order has 22 items

Substitute x =22 in equation

\(\hat{y}=3.0979+2.7633(22)\)

\(\hat{y}=63.8905\)

Hence the predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes

The probabilities are given as follows:

a) At most 3.8 percent: 0.0455 = 4.55%.

b) At most 8 percent: 0.9382 = 93.82%.

c) Between 3.8 and 8 percent: 0.8927 = 89.27%.

The z-score of a measure X of a variable that has mean symbolized by \(\mu\) and standard deviation symbolized by \(\sigma\) is obtained by the rule presented as follows:

\(Z = \frac{X - \mu}{\sigma}\)

The mean and the standard deviation for this problem are given as follows:

\(\mu = 6, \sigma = 1.3\)

The probability of at most 3.8% is the p-value of Z when X = 3.8, hence:

Z = (3.8 - 6)/1.3

Z = -1.69

Z = -1.69 has a p-value of 0.0455.

The probability of at most 8% is the p-value of Z when X = 8, hence:

Z = (8 - 6)/1.3

Z = 1.54

Z = 1.54 has a p-value of 0.9382.

Hence the probability of a value between these two values is given as follows:

0.9382 - 0.0455 = 0.8927.

Answer:

To find the amount of the sales tax, we need to multiply the bill amount by the tax rate of 3% or 0.03:

Sales tax = 0.03 x $16.05 = $0.48

To find the total amount of the bill after the sales tax was added, we need to add the bill amount to the sales tax:

Total bill = $16.05 + $0.48 = $16.53

To find the amount of the tip, we need to calculate 18% of the total bill after the sales tax was added:

Tip = 0.18 x $16.53 = $2.98

Rounding to the nearest cent, Penelope left a tip of $2.98.

Step-by-step explanation:

Mike completed 8 questions in one hour, and Clark completed 15 questions in 2 hours. To find how many questions Clark completed in one hour in order to compare the two, you can make an equation where x = the number of hours.

2x = 15

Divide both sides by 2.

x = 7.5

So Clark completed about 7.5 questions per hour, which is less than Mike's 8 questions per hour. However, only the second statement is true because the fourth one makes no sense - Clark didn't complete 2 questions, he did 14 in two hours, and 7.5 in 1.

The given inequalities are

y < - x/2

y ≥2x + 3

We would select points from each region and input them into the inequalities.

For region A, (3, 3)

Substitute x = 3 and y = 3 into each inequality. We have

For

y < - x/2,

3 < - 3/2

This is not true

For region B, (- 3, 3)

Substitute x = - 3 and y = 3 into each inequality. We have

For

y < - x/2,

3 < - -3/2

3 < 3/2

This is not true

For region C, (- 4, - 2)

Substitute x = - 4 and y = - 2 into each inequality. We have

For

y < - x/2,

- 2 < - -4/2

- 2 < 2

This is true

For y ≥2x + 3

- 2 ≥ 2(- 4) + 3

- 2 ≥ - 8 + 3

- 2 ≥ - 5

This is also true

Since both inequalities are satisfied in region C,

the correct option is C

Step-by-step explanation:

She has no more to spend than $55, which means the starting equation is:
x<=55.

She wants to buy ONE pair of pants, which means that you have to subtract 55 by 19.95.

55-19.95=35.05;

x<=35.05;

Each t-shirt costs 9.5 each, which means the equation is now

9.5x<=35.05

Which, if you divide by 9.5 on both sides, is

x<=3.68947368.

So, at most, she can buy 3 shirts.

Under the units-of-activity method, the depreciation expense per mile for Bus #3 is $0.4616.

The units-of-activity method is one of the depreciation methods in use.

Under the units-of-activity method, the depreciation expense per unit is determined by dividing the depreciable amount by the total units of activity.

The depreciation amount (the value of the asset subject to depreciation) is the net of the total cost less the salvage value.

Depreciable amount of Bus #3 = $57,700 ($66,500 - $8,800)

Expected total miles for Bus #3 = 125,000

Depreciation expense per mile for Bus #3 = $0.4616 ($57,700 ÷ 125,000)

\(m_{perpendicular}\) = 6

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

x + 6y = - 24 ( subtract x from both sides )

6y = - x - 24 ( divide through by 6 )

y = - \(\frac{1}{6}\) x - 4 ← in slope- intercept form

with slope m = - \(\frac{1}{6}\)

given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{-\frac{1}{6} }\) = 6

(c) 15i + 4b ≥ 100 inequality represents this scenario.

To represent the scenario described in the problem, we need to use an inequality that relates the amount of money Emily spends on ink and brushes to the total amount of money she has available. Let's call the amount of ink Emily buys "x" and the number of brushes "y". Then the total amount of money she spends is:

Total cost = 8x + 18y

We want to know when this total cost is less than or equal to $100, so we can write:

8x + 18y ≤ 100

This inequality means that the total cost of ink and brushes must be less than or equal to the amount of money Emily has available. Therefore, the answer is (c) 15i + 4b ≥ 100.

The answer of the given question based on percentage of the no. of officers that are male are approximately 21.3% of the police officers are male.

Multiply the number by the percentage you want to find, expressed as a decimal. For example, if you want to find 20% of 100, you would multiply 100 by 0.20.

The result of step 1 is the percentage of the number you're looking for. In the example above, 20% of 100 is 20.

If you want to express the result as a percentage, simply multiply the result by 100 and add the percent sign. In the example above, 20 times 100 is 2000, so 20% of 100 is equivalent to 2000%.

To summarize, the formula to find the percentage of any number is:

Percentage of a number = (percentage expressed as a decimal) x (the number)

To find the percentage of police officers who are male, we need to add up the number of male officers and divide it by the total number of officers, then we multiply by 100 to convert to percentage.

From the table, we can see that there are 170 officers in total who are male. Therefore:

Percentage of officers who are male = (number of male officers / total number of officers) x 100

= (170 / 800) x 100

= 21.25%

Rounding to the nearest tenth of a percent gives us:

Percentage of officers who are male = 21.3% (rounded to one decimal place)

Therefore, approximately 21.3% of the police officers are male.

Answer:

Starting with the equation:

(x + 1)^2 = 13/4

We can use the square root property, which states that if a^2 = b, then a is equal to the positive or negative square root of b.

Taking the square root of both sides, we get:

x + 1 = ±√(13/4)

Simplifying under the radical:

x + 1 = ±(√13)/2

Now we can solve for x by subtracting 1 from both sides:

x = -1 ± (√13)/2

Therefore, the solutions to the equation are:

x = -1 + (√13)/2 or x = -1 - (√13)/2

y - 7 = 1 (x-5)

Step-by-step explanation:

The point slope equation of a line is expressed as;

y - y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

Given the following

m = 1

(x0, y0) = (5, 7)

Substitute into the formula

y - 7 = 1 (x - 5)

y - 7 = x -5

y = x - 5 + 7

y = x + 2

Hence the point slope equation of the line is y - 7 = 1 (x-5)

We have a triangle with 2 sides of length 15 and 19.

We have to find the smallest possible whole number length for the 3rd side.

We can draw this as:

The third size is x.

If we reduce h, approaching to 0, x is minimized.

When h is very close to 0 (if h=0, the triangle cease to exist), the value of x can be written as a little bigger than the difference between the largest side (19) and the other side (15).

Then, x is, in the limit h-->0:

As x>4, the next whole number is 5.

NOTE: if x=4, the triangle does not exist, as there is no height or 3 angles.

Answer: The smallest whole number length for the 3rd side is 5.
