add the like terms that are on the left, then isolate the variable (a) on the left by dividing both sides by .

2a + 6a = -24

8a = -24 added like terms (2a + 6a)

8a/8 = -24/8 divided both sides by 8

a = -3 simplified (8/8 = 1 and -24/8 = -3)

Answer: -3

A cotton candy vendor has 10 cones of blue cotton candy to sell. If the blue cotton candy is 25% of the total number of cones, h

LenKa [72]

Answer: 40 cones

Explanation: If the blue cones (of which there are 10) are 25% or one quarter of the total number of cones, that means that the total number is equal to four times that, or 40.

10 = 25%
total = 100%
25% x 4 = 100%
10 x 4 = 40

A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore. Suppose that a storm is in progress wit

shtirl [24]

Answer:

The alternate hypothesis is:

$H_{a} < 16$

Step-by-step explanation:

There are two types of hypothesis. The null hypothesis and the alternate hypothesis. The null hypothesis is that the mean found is equal to the expected value. The alternate hypothesis is a question about this expected value(different, more, less)

A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore.

This means that the null hypothesis is $H_{0} = 16.4$

Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis

Dying down means lower average peak, that is, lower than the average of 16.4. This means that the alternate hypothesis is:

$H_{a} < 16$

sergejj [24]

Cubic root (x+8)=-4
Solving for x:
[cubic root (x+8)]^3=(-4)^3
x+8=-64
x+8-8=-64-8
x=-72

Answer: The solution is x=-72
