Answer:

Equivalent: 6(y - 3) AND 2(3y - 9)

Not Equivalent: 3(y - 6) AND 2(y - 9)

Step-by-step explanation:

4y - 2(5 - y + 4)

4y - 2(9 - y)

4y - 18 + 2y

6y - 18 (Everything must be equivalent to this)

3(y - 6) NOT EQUIVALENT

3y - 18

6(y - 3) EQUIVALENT

6y - 18

2(y - 9) NOT EQUIVALENT

2y - 18

2(3y - 9) EQUIVALENT

6y - 18

What is one third the difference between 3/4 and 2/3?
Ivan

Answer:

One third the difference between 3/4 and 2/3  is (\frac{1}{36} )

Step-by-step explanation:

One third the difference of A and B  =  \frac{1}{3} \times (A-B)

Here, as given in the question:

A = \frac{3}{4} , B = \frac{2}{3} \\\implies A  - B =  \frac{3}{4} - \frac{2}{3}\\=(\frac{3 \times 3 -2 \times 4}{12})  = (\frac{9-8}{12} ) = (\frac{1}{12})\\ \implies  A  - B =  (\frac{1}{12})

Now, one third of the difference is :

(\frac{1}{3}) \times (\frac{1}{12}) =   (\frac{1}{36})

Hence, one third the difference between 3/4 and 2/3  is (\frac{1}{36} )

To help consumers assess the risks they are taking, the Food and Drug Administration (FDA) publishes the amount of nicotine foun
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.

Adam would like to buy a used car, and collected several data to evaluate the best model (such as age, price, weight, etc.) Than
9966 [12]

Answer: There is a strong association between age and weight.

Step-by-step explanation:

The correlation coefficient (r) is used to describe the relationship between two variables.

-1\leq r\leq1

If r lies between -1 to -0.5 or 0.5 to 1, then there is strong association between them.

Here,  Variables: Age and weight.

correlation coefficient = 0.512

That means, there is a strong association between age and weight.
