300 / (600 + 300 + 800) = 300/1700 = 3/17

Answer:

y +8 = -4(x -8)

Step-by-step explanation:

You recognize that the given equation is in slope-intercept form:

y = mx + b

with m = 1/4 and b = 5.

A perpendicular line will have a slope that is the negative reciprocal of this value of m, so the desired slope is ...

-1/m = -1/(1/4) = -4

The point-slope form of the equation for a line is ...

y -k = m(x -h) . . . . . for slope m through point (h, k)

Using m=-4 and (h, k) = (8, -8), the point-slope form of the equation for the line you want is ...

y +8 = -4(x -8)

True or false and if false what would be the correct term be?

vagabundo [1.1K]

It’s True.. you take the “extreme” variable from each proportion and cross multiply them before setting them equal to the product of the two “means” (which are just the other 2 numbers in the proportions).

what is the answer to the volleyball team at blue point high school has saved $680 and the team plans to spend no more then that

zloy xaker [14]

Answer:

6 x + 23 y < $ 680 represents the combinations of x balls and y nets that can be purchased.

Step-by-step explanation:

The number of balls than can be purchased = x

The number of nets than can be purchased = y

Total savings = $ 680

Now, the cost of 1 ball =$6

So, the cost of x balls = x ( cost of 1 ball) = x ( $6) = 6 x

Also, the cost of 1 net =$23

So, the cost of y nets = y ( cost of 1 net = y ( $23) = 23 y

So, the total amount spent on x balls and y nets

= Amount spent on x balls + Amount on y nets

= 6 x + 23 y

Also, the saved amount is $680

⇒<u> 6 x + 23 y < $ 680</u>

Hence, 6 x + 23 y < $ 680 represents the combinations of x balls and y nets that can be purchased.

Just replace X with the given value.

X = -3

f(-3) = 5 - (-3)

f(-3) = 5 +3

f(-3) = 8

Test the claim that the proportion of men who own cats is smaller than 70% at the 0.05 significance level. The null and alternat

Ghella [55]

Answer:

the null hypothesis would be: p = 70%/0.7

The alternative hypothesis would be: p < 0.7

Step-by-step explanation:

The null hypothesis is most of the time always the default statement while the alternative hypothesis is tested against the null and is its opposite.

In this case study the null hypothesis would be: the proportion of men who own cats is 70%: p = 0.7

The alternative hypothesis would be: the proportion of men who own cats is smaller than 70% : p < 0.7
