The length of a rectangular field is 6 feet less than 5 times its width.

Its area is 306 square feet.
Find the Width and length

Answers

Answer:

5X-6)+(5X-6)+X+X=252 , now lets add all the X together, and then add the whole numbers.

12X-12=252 , now lets work this by adding 12 on each side of the equation:

12X-12+12=252+12

12X=264 , divide both sides by 12.

X=22

Now lets prove X =22:

(5·22–6)+(5·22–6)+22+22=252

(110–6)+(110–6)+22+22=252

104+104+44=252

208+44=252

252=252Therefore the length is 104 feet each and the width is 22 feet each.

Answers

Answer:

x = 66 degrees, y = 57 degrees

Step-by-step explanation:

180 - 123 = 57 = y

57 + 57 + x = 180

114 + x = 180

x = 66

Answer:

x = 70

y = 55

Step-by-step explanation:

Exterior angle = Sum of opposite angles

x + y = 125

y + 125 = 180

( because this is an isosceles triangle )

y = 180 - 125

y = 55

Substitute y = 55 in eq. x + y = 125,

x + 55 = 125

x = 125 - 55

x = 70

A sample of restaurants in a city shows that the average cost of an appetizer is $6.32 with a standard deviation of $0.47. A brand new restaurant wants to get noticed by offering appetizers for a much lower price. To determine the lower price, should the formula use a z-value that is greater than or less than -1?
a.
Greater than -1
c.
Greater than 1
b.
Less than -1
d.
Either way, it doesn’t matter

Answers

Answer:

D

Step-by-step explanation:

Is the corrext answer hope it helps

By using a z-value less than -1, we can find a price that is significantly lower than the average cost, and therefore more likely to attract customers.

Option B is the correct answer.

What is a standard deviation?

Standard deviation is a measure of the amount of variability or spread in a set of data.

It is calculated as the square root of the variance and is often denoted by the symbol σ (sigma) for a population and s for a sample.

We have,

The z-value formula is used to determine the number of standard deviations a data point is from the mean.

To determine the lower price of appetizers, we want to find a price that is significantly lower than the average cost.

Since the new restaurant wants to offer appetizers for a much lower price, we should use a z-value that is less than -1, which indicates a price that is more than one standard deviation below the mean.

Recall that the z-value formula is:

z = (x - μ) / σ

where x is the value of interest, μ is the mean, and σ is the standard deviation.

Thus,

By using a z-value less than -1, we can find a price that is significantly lower than the average cost, and therefore more likely to attract customers.
