Answer: 18 girls to 12 boys

Step-by-step explanation: We can write a ratio using the word "to", using a colon, or using a fraction bar.

Let's write the ratio using the word "to."

Since there are 18 girls and 12 boys,

we can write this as 18 girls to 12 boys.

So this would be our answer.

However, this can be reduced to 3 girls to 4 boys.

Solve the system of equations. -12x-5y=40 and 12x-11y=88 x= y=
SpyIntel [72]

Answer:

(0,-8)

x=0

y=-8

Step-by-step explanation:

There are a couple of ways you can solve this I used what I think is called the elimination method

We first start by writing the equations in linear form (y=mx+b)

For the first one we have -12x-5y=40

we add 5y to both sides and subtract 40 to get

-12x-40=5y

divide by 5 to get

-12/5x-8=y

Then the second one we have

12x-11y=88

same deal here, add 11y and subtract 88 to get

12x-88=11y

divide by 11 and get

12/11x-8=y

We then set the two equations equal to each other and get

-12/5x-8=12/11x-8

We can add 8 to both sides and get

-12/5x=12/11x

Just by looking at it you can see that the only solution for x is 0

Plug in 0 to the first equation and get -12*0-5y=40

This means that -5y=40

Solve for y and get -8

Given m∠P = 38° and m∠O = 70°, find m∠1.<br><br> 38<br> 72<br> 108<br> 142
adoni [48]

m<1 + m<O + m<P = 180°

m<1 + 70° + 38° = 180°

m<1 + 108° = 180°

m<1 = 72°

A local weather enthusiast wants to see if the last five summers have been warmer than normal for Eloy, Arizona. From the Nation
lys-0071 [83]

Answer:


Step-by-step explanation:

This is a question on hypothesis testing.

Population mean based on 30 year average for July was 90 with

a std deviation of 2.1

Sample of 5 shows average 93.5

To check whether sample average = population average

H0: x bar =90

Ha: x bar not equal 90(Two tailed test)

Test statistic = \frac{93.5-90}{\frac{2.1}{\sqrt{5} } }

=3.73

Since this lies outside the range (-1.96, 1.96) we reject null hypothesis

Hence we cannot say sample mean equals 90
