The product of 340 and 6. Are they multiplied or is it divided

1 answer:

3 0

The term product is always used as a process for multiplication. So they are multiplied.
However, the quotient is used for division, if you want to divide something.

Hope this helps :)

I need help with answering question 16 on spring board algebra 2 pg. 35 the questions says solve the system using substitution t

Jet001 [13]

Answer:

x = 147

y = 32

Step-by-step explanation:

I got a bit confused by what you said, but I think you need help being shown how to do 16, so hopefully the following will help!

So to use substitution you "plug in" the expression into each other. Here is what to do for 16!

[] First, we need to find which expression can be plugged in. The first one works! It is set equal to x, so we can easily plug it in.

[] Now, we need to set up our equation!

3y - x = -13

4y + 19 = x

3y - 4y + 19 = -13

[] Now, we <u>solve for y</u> and simplfy!

3y - 4y + 19 = -13

-y = -32

(I subtracted 19 for both sides and combined the y's)

Now I am going to add -y and -32 to both sides so I can have it be positive.

y = 32

[] Last, but not least, we <u>solve for x</u>!

- Plug the y you just solved into the equation for x

4y + 19 = x

4(32) + 19 = x

128 + 19 = x

147 = x

(hopefully this is correct, have a nice day!)

Vlad [161]

Answer:

The t-statistic that Jacob calculates is $t = -2.71$

Step-by-step explanation:

Jacob knows that the adult population gets, on average, eight hours of sleep each night. A hypothesis test can help him see if college students are different from the adult population.

At the null hypothesis, we test if the mean is of 8 hours, that is:

$H_0: \mu = 8$

At the alternative hypothesis, we test if the mean is different of 8 hours, that is:

$H_1: \mu \neq 8$

The test statistic is:

$t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}$

In which X is the sample mean, $\mu$ is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.

8 is tested at the null hypothesis:

This means that $\mu = 8$

From a sample of 101 students, Jacob tabulated that his sample of students got an average of 7.3 hours of sleep each night, with a standard deviation of 2.6.

This means that $n = 101, X = 7.3, s = 2.6$

What is the t-statistic that Jacob calculates?

$t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}$

$t = \frac{7.3 - 8}{\frac{2.6}{\sqrt{101}}}$

$t = -2.71$

The t-statistic that Jacob calculates is $t = -2.71$

A line has a slope of 7 and a

musickatia [10]

Answer:

The answer is y=7x-15

Step-by-step explanation:

The formula for slope is y=mx+b where m is the slope, or the rate of change, and b is the y-intercept, or the initial value, which is the point where x=0.

The rate of change, or slope, is 7, so m will be replaced with 7.

-15 is the y-intercept, so b will be replaced with -15.

Therefore, the slope-intercept form is y=7x-15.
