Answer:

The answer to this problem is x = 2.

Step-by-step explanation:

To solve this problem, we need to get the variable x's alone on one side of the equation.  The first step is to combine like terms on the left side of the equation, which means combining the two constant terms and two variable terms. This is modeled below:

2x - 3 + 7x + 1 = 16

(2x + 7x) + (-3 + 1) = 16

9x - 2 = 16

Next, we should add 2 to both sides to get the variable term alone on the left side of the equation.

9x - 2 + 2 = 16 + 2

9x = 18

Then, we should divide both sides of the equation by 9 in order to get rid of the coefficient on the x.

9x/9 = 18/9

x = 2

Therefore, the answer is x = 2.

Hope this helps!

Step 1: Simplify both sides of the equation.

2x−3+7x+1=16

2x+−3+7x+1=16

(2x+7x)+(−3+1)=16(Combine Like Terms)

9x+−2=16

9x−2=16

Step 2: Add 2 to both sides.

9x−2+2=16+2

9x=18

Step 3: Divide both sides by 9.

9x /9   =  18 /9

Therefore, x=2

Answer:

x is 2.

An insurance company sets up a statistical test with a null hypothesis that the average time for processing a claim is 7 days, a
JulsSmile [24]

Answer:

There was no error

Step-by-step explanation:

There are two types of statistical errors, the type 1 error and the type 2 error. In this case we refute the null hypothesis when the hypothesis is, in fact, false, because the mean process is 9 days instead of 7. Therefore we made no errors.

If the null hypothesis were True, a type 1 error would have ocurred. If the null hypothesis were false and we didnt refute it, then a type 2 error would have ocurred.

If sin X = 0.3240 and b = 40, what is the value of c
storchak [24]

Answer:

123.46 or 42.28

Step-by-step explanation:

Assuming that b is the leg side of a triangle and that c is the hypotenuse, we can solve for c using SOHCAHTOA.

We can find the angle from the equation sin X = 0.3240.

X = sin^{-1} 0.3240

X = ...

Through SOHCAHTOA, we know that we should use either sin X = \frac{opp}{hyp}  or that cos X = \frac{adj}{hyp}.

I'm going to assume that we use sin X = \frac{opp}{hyp} since we are given a length b and not a length a. So:

sin 18.9050 = \frac{40}{c}

c =  \frac{40}{sin 18.9050} = 123.46

If we use cos X = \frac{adj}{hyp}, then:

cos 18.9050 = \frac{40}{c}

c =  \frac{40}{cos 18.9050} = 42.28

Not sure which one is correct since we are not given a picture of the sides.
