Answers

Answer 1

Answer:

93/100

Step-by-step explanation:

In a group of 100 students, 60 are freshman, 55 are female, and 22 are female freshman. Find the probability that a student picked from this group at random is either a freshman or female

Number of Freshman = 60

Number of female = 55

Number of Freshman female 22

Total number of students = 100

The probability that a student picked from this group at random is either a freshman or female

Thus P(freshman or female) = 60/100 + 55/100 - 22/100 = 93/100

Answers

Answer:

x = 15

Step-by-step explanation:

x + 2y = 37

x - y = 4

x + 2y = 37

2x - 2y = 8

3x = 45

x = 15

Answer: (4) x = 15

Steps:
1. Isolate y in the equation x - y = 4
x - y = 4
-y = 4 - x
y = 4 - x / -1
2. Substitute value of x (15) into the new equation y = 4 - x / -1
y = 4 - 15 / -1
y = -11 / -1
y = 11
3. Plug in your y value (11) and x value (15) into the equation x + 2y = 37
15 + 2(11) = 37
15 + 22 = 37
37 = 37 ✅
4. Plug in your y value (11) and x value (15) into the equation x - y = 4
15 - 11 = 4
4 = 4 ✅

both equations are true with the value of x being 15 therefore your answer is
(4) x = 15

have a great day!!!

If two ratios are similar we called the ratios to be in proportion.

The length of side x is 6 cm.

What is proportion?

If two ratios are similar we called the ratios to be in proportion

We have,

Two shapes:

Consider the bigger shape width = 15 cm and length = 10 cm.

Consider the smaller shape width = 9 cm and length = x cm.

Let the ratio of bigger shape:

= Width / length

= 15/10

Let the ratio of smaller shape:

= Width / length

= 9/x

If the two figures are mathematically similar we can say that the two figures are in proportion.

We can write it as:

15/10 = 9/x

3/2 = 9/x

x = 6

Thus the length of side x is 6 cm.

Step-by-step explanation:

When solving 8x-8≤-72, first add 8 to both sides of the inequality.

This leaves you with 8x≤-64.

Divide both sides by 8: 8x/8 and -64/8

This leaves you with x≤-8 as your solution.

ROUND YOUR ANSWER TO THE NEAREST HUNDREDTHS. *

Answers

Answer:

Twenty cookies deal

Step-by-step explanation:

A dozen cookies cost 18.75. A dozen is exactly 12. If you divide 18.75 by 12 you should get the unit price which is about $1.56 for each cookie. For 25.50 you just divide it by 20 and you should get about 1.20 which makes it a better deal.

Sra bought a pair of shoes that were on sale for 30 percent off. If the oringal prices was 29 what is the sale price on the shoes?

Answers

Answer:

$20.30

Step-by-step explanation:

Original price = 100% of the price

100% = $29

1% = 29 ÷ 100 = 0.29

Sale percentage = 30%

30% = 0.29 x 30 = 8.70

Since they are asking for the sale price of the shoes, it means the price of the shoes after the discount of the sale percentage.

29 - 8.70 = 20.3
