A company vehicle is available in black or blue. A random sample includes seven black vehicles and five blue vehicles. If there are 300 vehicles then how many are blue

125 blue vehicles

Step-by-step explanation:

In this question, we are going to estimate the number of vehicles of a specific color given that there are some numbers of both vehicle models present in a sample.

Now to solve this question, we are going to treat the sample numbers as a ratio.

The ratio here is thus 7 black to 5 blue I.e 7:5

We have 300 vehicles, we now want to estimate the number of blue vehicles present.

From the sample ratio, there are a total of 12 vehicles

Now the total number of blue vehicles would be 5/12 * 300 = 125

There are 125 blue vehicles

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?
