Alright, this is a lot.

This start with the first question (3)

Find the product of 5(18) and 5(18) = 90

To get that is 5(18) = (5 x 18 = 90)

So now we have to do the math for both A and B and find out which one is 90

A 5(10+8) : 10 + 8 = 18 so (a) = 5(18)
B 5(20-2) : 20 - 2 = 18 also well

I think (a) would be your best bet. For question (3)

Alright question 4

(a) = 8x + 40
(b) = 4y - 36
(c) = -6n - 18
(d) = 7x + 7
(e) = 30-10x
(f) = 4x + 2

Hope this helps in any way. Tell me if It's right

QveST [7]

Answer:

We conclude that the mean nicotine content is less than 31.7 milligrams for this brand of cigarette.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 31.7 milligrams

Sample mean, $\bar{x}$ = 28.5 milligrams

Sample size, n = 9

Alpha, α = 0.05

Sample standard deviation, s = 2.8 milligrams

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 31.7\text{ milligrams}\\H_A: \mu < 31.7\text{ milligrams}$

We use One-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{28.5 - 31.7}{\frac{2.8}{\sqrt{9}} } = -3.429$

Now, $t_{critical} \text{ at 0.05 level of significance, 8 degree of freedom } = -1.860$

Since,

$t_{stat} < t_{critical}$

We fail to accept the null hypothesis and accept the alternate hypothesis. We conclude that the mean nicotine content is less than 31.7 milligrams for this brand of cigarette.
