Find the measure of the missing angle

crimeas [40]

Answer:

g=118 degrees h=62 degrees

Step-by-step explanation:

So we can use some angle rules that I forget the name of to solve this.

Let's look at angle g first. We know that the opposite angle is 118 degrees. So that also means that g is going to be 118 degrees.

Since g is 118 degrees we can find h. The angle of a line is 180 degrees. This means that we can do 180-118 to find h. h=62 degrees.

We can do the same thing for k and m. Try doing what I did for g and h for those two. Comment if you need help.

hardware stores sells copper pipes for $24 per 5 foot piece a project requires 6 inches of pipe will be the cost of the pipe for

kiruha [24]

The hardware store sells copper pipes for $24 per 5 feet right? so, 5 feet is equal to 60 inches and since you need 6 inches, you divide 60 by 10 to get 6 and also divide 24 by ten and you get 2.4, so the answer is $2.4 for 6 inches of pipe.

Hope this helps!

Suppose that 950 couples each have a baby find the mean and standard deviation for the number of boys in the 950 babies

nydimaria [60]

The mean and standard deviation for the number of boys in the 950 babies are 475 and 15.41, respectively

<h3>How to determine the mean and the standard deviation?</h3>

From the complete question, we have:

P(boy)= 0.5

Sample size = 950

The mean is then calculated as:

$\bar x = np$

This gives

$\bar x = 950 * 0.5$

Evaluate

$\bar x = 475$

The standard deviation is calculated as:

$\sigma = \sqrt{np(1 - p)$

This gives

$\sigma = \sqrt{950 * 0.5(1 - 0.5)$

Evaluate

$\sigma = 15.41$

Hence, the mean and standard deviation for the number of boys in the 950 babies are 475 and 15.41, respectively

PLZ HELP!!!!!!A trapezoid has an area of 230.945 square meters. One base is 7.7 meters long. The height measures 18.7 meters. Wh

Amanda [17]

Answer:

17m

(Anyone can correct me if I'm wrong)

Step-by-step explanation:

The following equation would be used: $A=\frac{a+b}{2} h$

We would simply substitute the given values, move the values around then we would get our answer:

$230.945=18.7\frac{7.7+b}{2}\\\\230.945=9.35(7.7+b)\\\\b+7.7=24.7\\\\b=17m$
