Answer:

1a. 4(p+4)-9 = (4p+16)-(9) = 4p+7

2a. 10a+5-7a = (10a-7a)+(5) = 3a+5

3a. 10+9v-10-6v = (10-10)+(9v-6v) = 0+3v = 3v

4a. (t+2)-6 = t+2-6 = t-4

5a. 10-3x+7x+5+9x = (10+5)+(-3x+7x+9x) = 15+13x

6a. 5b-3b = 2b

7a. 7s-4+5-7s = (7s-7s)+(-4+5) = 0+1 = 1

1b. 3+(8b+5) = 3+8b+5 = (3+5)+8b = 8+8b = 1+b

2b. 2-3p+7p+10+p = (2+10)+(-3p+7p+p) = 12+5p

3b. 10+2(t+6) = 10+2t+12 = 22+2t = 11+t

4b. 7-8p+5p+10+6p = (7+10)+(-8p+5p+6p) = 17+3p

5b. 10+7(6y+5) = 10+42y+35 = (10+35)+42y = 45+42y

6b. w^4*w^2 = w^6

7b. 6p+5p = 11p

A company advertises that its cans of caviar each contain 100 g of their product. A consumer advocacy group doubts this claim, a
Blizzard [7]

Answer:

The value of the test statistic is -3.14.

Step-by-step explanation:

Test statistic:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the expected value, \sigma is the standard deviation and n is the size of the sample.

A company advertises that its cans of caviar each contain 100 g of their product.

This means that \mu = 100

They calculate a sample mean weight of 99 g and a sample standard deviation of 0.9 g. Sample of 8 cans.

This means that X = 99, \sigma = 0.9, n = 8

So the test statistic will be given by:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

t = \frac{99 - 100}{\frac{0.9}{\sqrt{8}}}

t = -3.14

The value of the test statistic is -3.14.

What is the slope of the line?
Katyanochek1 [597]

Answer:

1

Step-by-step explanation:

slope (k) is the rise over run of the line

a way of finding the slope if you have two dots of the line is:

k \:  =  \frac{y2 - y2}{x2 - x2}

here the dots that belong to the line that you can most easily see are:

A(-6,0)

B(0,6)

by inserting the values into the euquation you get:

\frac{6 - 0}{0 - ( - 6)}  =  \frac{6}{6}  = 1

good luck with your maths solving
