Answer:

$1.80, $2.90, $4.00, $10.90

Step-by-step explanation:

For 9/10 mile, the price will be $1.80. For 2 miles, the price will be $2.90. For 3 1/10 miles, the price will be $4.00, and for 10 miles, the price will be $10.90. The relationship between distance travelled and the price is not proportional because it costs $1.00 for the first 1/10 mile and then for every additional 1/10 mile, it only costs $0.10. Hope it helps!

Answer:

a) i) This is a right-tailed test.

$\text{Test statistic} = 1.08$

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 23 pounds

Sample mean, $\bar{x}$ = 23.6 pounds

Sample size, n = 40

Alpha, α = 0.10

Sample standard deviation, s = 3.5 pounds

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 23\text{ pounds}\\H_A: \mu > 23\text{ pounds}$

This is a one tailed(right).

Formula:

$\text{Test statistic} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$

Putting all the values, we have

$\text{Test statistic} = \displaystyle\frac{23.6 - 23}{\frac{3.5}{\sqrt{40}} } = 1.08$

ECTIONS: Write an expression that represents the situation.

KatRina [158]

an expression that determine the total cost of gym membership for any number of months is 10+19.99(x)

Given that:

cost per month = $19.99

Starting fee = $10

Months = x

So the expression for 1 person will be:

10+ 19.99(x)

thus an expression that determine the total cost of gym membership for any number of months is 10+19.99(x)
