Answer:
y = 3
Step-by-step explanation:
Take 2 points from the graph: (1,3) (-1,3)
Use those 2 points to find the slope and y-intercept.
Slope: 3 - 3 / - 1 - 1 => 0 / -2 => 0
Slope is 0.
The y-intercept is (0,3)
hence, the equation will be y = 3

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?

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.

How many 3 digit numbers can you make using these numbers: 4,2,9 (numbers can be reapeated)
Answers
Answer:
You can make 27 different 3 digit numbers
Step-by-step explanation:
Since we can use 3 different numbers this means that each of the 3 digits can be one of the 3 numbers (4,2,9). This means that there are 3 different values for the first digit, 3 different values for the second digit, and 3 different values for the third digit, which mean that we can make 3 x 3 x 3 different 3 digit numbers (we took the number of possible values for each digit and multiplied them together.
3 x 3 x 3 = 27

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

Amy knits 1/10 of a scarf in 4/5 of an hour. What fraction of scarf can Amy knit in 1 hour
Answers
Answer:
Amy can knit [tex]\frac{1}{8}[/tex] of a scarf in 1 hour.
Step-by-step explanation:
This question can be solved by proportions, using a rule of three.
We have that:
1/10 of a scarf - 4/5 of an hour
x of a scarf - 1 hours.
Applying cross multiplication:
[tex]\frac{4x}{5} = \frac{1}{10}[/tex]
[tex]x = \frac{5}{10*4} = \frac{5}{40} = \frac{1}{8}[/tex]
Amy can knit [tex]\frac{1}{8}[/tex] of a scarf in 1 hour.
