Using the normal distribution, the upper boundary, in inches, of a symmetric and centered interval of the sample averages with n = 167 that are within 0.92 standard deviation s of the mean is of:

67.21 inches.

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Considering samples of 167, with the mean and standard deviation of the population given in the problem, the parameters are given as follows:

[tex]\mu = 66.9, \sigma = 4.33, n = 167, s = \frac{4.33}{\sqrt{167}} = 0.335[/tex]

The desired height is X when Z = 0.92, because it is 0.92 standard deviations from the mean and we want the upper limit, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

0.92 = (X - 66.9)/0.335

X - 66.9 = 0.92 x 0.335

X = 67.21 inches.

Answer:

A: Reflection over the y-axis

B: Translation 3 right

C: Translation 4 down

D: Reflection over the x-axis

Step-by-step explanation:

A: This is a reflection over the y axis because we can tell it has been flipped to the other side, vertically.

B: Count the spaces between the two 'P's, getting 3 to the right. This is not a reflection because it is facing the same way.

C: Count the spaces between the two 'P's, getting 4 down. Again, this is not a reflection because it is facing the same way.

D. This is a reflection over the x axis because we can tell it has been flipped to the other side, horizontally.

The sample proportion saying that the food is delicious will be approximately normal.

In this question, we have been given that 87% of the people who sampled their food said that it was delicious

so, the Population proportion = 87%

A random sample of 144 people is obtained from a population of 5,000. The 144 people are asked to sample the caterer's food.

The sample size of 144 from 5000 will have proportion p cap which will follow a normal distribution with mean= p = 87%

The equation of the line that has the given features is y = -1/3x - 4

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

From the question, the given parameters are

Slope, m = -2

y-intercept, c = 9

As a general rule:

A linear equation is represented as

y = slope * x + y-intercept

This can be rewritten as

y = mx + c

Next, we substitute the known values in the above equation

So, we have the following equation

y = -2x + 9

The above equation cannot be further simplified

So, we have

y = -2x + 9

However, it can also be expressed as

y = 9 - 2x

Hence. the linear equation is y = -1/3x - 4

Answer: It would be "In an Old House"

Step-by-step explanation:

a) quotient = 23 and remainder = 14

b)  quotient = 28 and remainder = 12.

c) quotient = 20 and remainder = 10.

a) Here in the first question we have to divide 405 by 17.

405 is not completely divisible by 17.

So when we divide 405 by 17 we get 23 as quotient and 14 as remainder.

we can cross check this by the formula;

Dividend= Divisor × Quotient + Remainder.

So in here the dividend is 405 and the divisor is 17 which when multiplied by the quotient 23 and added by the remainder that is 14 gives us 405.

Thus quotient = 23 and remainder = 14

b) Here dividend = 656 and divisor = 23

Thus when we divide 656 by 23 we get:

we get quotient as 28 and remainder as 12.

c) Given dividend is 1990 and divisor is 98.

Thus we divide 1990 by 98 we get:

Quotient = 20 and remainder = 10.

Answer:

Slope-intercept form is given as y = mx + c where m is the slope and c is the y-intercept.

Since slope = 2, equation is y = 2x + c.

Substitute (-1,2) into the equation to find c.

2 = 2(-1) + c

c = 4

Hence, equation is y = 2x + 4

Answer:

In a case whereby Apollo Spas services 298 hot tubs and each hot tub needs 175 mL of muriatic acid,number of liters of acid that are needed for all of the hot tubs is 52.15 litres.

The unit conversion can be described as the changing of bone unit to another.

We can calculate the number of liters of acid that are needed as (298 * 175)= 52150ml

This can be converted to liter by dividing  52150ml by 1000 which  can be done as (52150ml/1000) = 52.15 litres of acid.

Therefore, the  liters of acid are needed for all of the hot tubs can be expressed as the 52.15 litres

Shop work on the customer's computer for 5.5 hours.

Given,

Charge is flat fee of $ 10.95

and, then $24.50 per hour.

And, to find the number of hours if customer paid $147.90.

Now, According to the question:

Let shop work on computer for x hours .

Then, Amount paid = 10.95 + 24.90x

So, if customer paid $147.90

then, 147.90 = 10.95 + 24.90x

24.90x = 147.90 - 10.95

24.90x = 136.95

x = 136.95/ 24.90

x = 5.5

The line which is parallel to 2x-2y=-4 that passes through the

point (3,9) is x-y = -6.

Given that, 2x-2y = -4 passes through the point (3,9) then we have to find the equation of a line which is parallel to the given equation of line.

Let's proceed to find the equation of the line.

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis).

Using the slope-intercept formula, the equation of the line is:

y = mx + b

where,

m = the slope of the line

b = y-intercept of the line

(x, y) represent every point on the line

x and y have to be kept as the variables while applying the above formula.

2x-2y = -4

-2y = -4-2x

y = -4/-2 - 2x/-2

y = 2+x

y = x+2

On comparing with y = mx+b

m = 1 and b = 2

As the lines are parallel then the slope of other line will also be same i.e., m = 1

The point from which it is passes is (3,9)

⇒ x₁ = 3 and y₁ = 9

y-y₁ = m(x-x₁)

⇒ y-9 = 1(x-3)

⇒ y-9 = x-3

⇒ y = x-3+9

⇒ y = x+6

⇒ x-y = -6

Therefore, the line which is parallel to 2x-2y=-4 that passes through the

point (3,9) is x-y = -6.

Hence, x-y = -6 is the required answer.
