After constructing a confidence interval estimate for a population mean, you believe that the interval is useless because it is

Solution:

Reflect the parent function across the x-axis and then shift it 8 units left.

Step-by-step clarification:

The function in question is

The parent function can be described as

Due to the negative multiplier applied to the transformed function, a reflection occurs along the x-axis.

As the value 8 is added within the square root, it indicates a horizontal shift of 8 units left.

Therefore, to accurately graph the given function, reflect the parent function over the x-axis and translate it to the left by 8 units.

Answer: the likelihood of a randomly selected tire lasting exactly 47,500 miles is 0.067

Step-by-step explanation:

Since the expected lifespan of this tire brand follows a normal distribution, we will use the normal distribution formula:

z = (x - µ)/σ

Where

x = lifespan of the tire in miles.

µ = mean

σ = standard deviation

The given figures include,

µ = 40000 miles

σ = 5000 miles

The probability that a tire will last precisely 47,500 miles

P(x = 47500)

For x = 47500,

z = (40000 - 47500) / 5000 = -1.5

According to the standard normal distribution table, the probability associated with this z score is 0.067

Answer:

Step-by-step explanation:

Delivery charge = $7.50

Cost per pizza = $14

Budgeted total = $60

7.50 + 14p < 60

First, subtract 7.50 from both sides

14p < 60 - 7.50

14p < 52.50

Now divide both sides by 14

p < 52.50 / 14

p < 3.75

Each pizza consists of 8 slices

Therefore, the total number of slices she can buy = 3.75 × 8

= 30 slices
