Step-by-step explanation:

oh lord here we go again

get the area of all signs again

5 x 5 = 25

theres 2 of those squares so make that 50

8 x 5 = 40

theres 4 of those sides so 40 x 4 = 160

10 x 10 = 100

theres two of those so its 200

2 x 10 = 20

4 of these so 80

add all the final ones

50 + 160 + 200 + 80 = 490

A survey showed that 35% of the students prefer plain white milk over chocolate milk. If the school has 1200 students. How many

Pani-rosa [81]

780 students prefer chocolate milk.

Step-by-step explanation:

Let,

the total percentage = 100%

Students who prefer plain white milk = 35%

Students who prefer chocolate milk = 100 - 35 = 65%

Number of students = 1200

No. of students who prefer chocolate milk = 65% of total students

No. of students who prefer chocolate milk = $\frac{65}{100}*1200$

No. of students who prefer chocolate milk = $\frac{78000}{100}\\$

No. of students who prefer chocolate milk = 780

780 students prefer chocolate milk.

A company has 8 mechanics and 6 electricians. If an employee is selected at random, what is the probability that they are an ele

Andre45 [30]

Answer:

$Probability = \frac{3}{7}$

Step-by-step explanation:

Given

Electrician = 6

Mechanic = 8

Required

Determine the probability of selecting an electrician

First, we need the total number of employees;

$Total = n(Electrician) + n(Mechanic)$

$Total = 6 + 8$

$Total = 14$

Next, is to determine the required probability using the following formula;

$Probability = \frac{n(Electrician)}{Total}$

$Probability = \frac{6}{14}$

Divide numerator and denominator by 2

$Probability = \frac{3}{7}$

<em>Hence, the probability of selecting an electrician is 3/7</em>
