So since this is a linear equation, which is y=mx+b, you use what it tells you in the word problem. so mx is the rate, since in this equation 200 per ton of sugar that's your mx, so its 200x. then for your b value, which in this case is the cost of truck rental, so its 5,400.

your equation is C=200s+5400


the variables are the same so you can use Y and X, but I used the variables used in the word problem.

Y=200x+5400

Sunny_sXe [5.5K]

Answer:

Since Her goal is to earn $ 300 , but now she is earning only $270 ,Hence Celia will not achieve her goal  .

Step-by-step explanation:

Given as :

The cost of each calendar = $ 9

The number of calendar sold to the family = 16

The number of calendar sold to the neighborhood = 14

So, Total number of calendar sold by Celia = The number of calendar sold to the family + The number of calendar sold to the neighborhood

i.e Total number of calendar sold by Celia = 16 + 14 = 30

∵ The cost of each calendar = $ 9

∴ The cost of 30 calendar = $ 9 × 30 = $ 270

Since Her goal is to earn $ 300 , but now she is earning only $270 ,Hence Celia will not achieve her goal  .  Answer

A random sample of 16 students selected from the student body of a large university had an average age of 25 years. We want to d
Gennadij [26K]

Answer:

Option D) significantly different from 24

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 24

Sample mean, \bar{x} = 25

Sample size, n = 16

Alpha, α = 0.05

Population standard deviation, σ = 2

First, we design the null and the alternate hypothesis

H_{0}: \mu = 24\text{ years}\\H_A: \mu \neq 24\text{ years}

We use Two-tailed z test to perform this hypothesis.

Formula:

z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }

Putting all the values, we have

z_{stat} = \displaystyle\frac{25 - 24}{\frac{2}{\sqrt{16}} } = 2

Now, z_{critical} \text{ at 0.05 level of significance } = \pm 1.96

Since,  

The calculated z statistic does not lie in the acceptance region, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.

Thus, it can be concluded that the mean age is

Option D) significantly different from 24
