84%

Step-by-step explanation:

21 correct + 4 wrong = 25 questions in total

[tex]\frac{21}{25}[/tex] x 4 = [tex]\frac{84}{100}[/tex]

[tex]\frac{84}{100}[/tex] = 0.84

0.84 = 84%

A school counselor surveyed 90 randomly selected students about the languages they speak. Of the students surveyed, 15 speak more than one language fluently. Based on these results, how many of the 1,800 students at the school can be expected to speak more than one language fluently? A.288 B.300 C.113 D.389

Answers

Answer:

b

Step-by-step explanation:

Because the population is too large and it would be impractical to survey the whole population, a sample of the population is chosen to take part in the survey. This sample is taken as been representative of the whole population

Based on the sample, the fraction of students that speak more than one language fluently = 15/90= 0.166667

Population that would speak more than one language fluently = 0.166667 x 1800 = 300

Answers

Answer:

<QRS = 55 degrees

Step-by-step explanation:

Given the following

m∠QRS=(10x−1) ∘

∠RPQ=(3x+17) ∘

m∠PQR=(2x+12)

External angle m<QRS = 10x-1

Interior angles are m∠RPQ=(3x+17) ∘ and m∠PQR=(2x+12)

Using the law that the sum of interior angle is equal to exterior

10x + 1 = 3x+17 + 2x + 12

10x+1 = 5x+29

10x-5x = 29-1

5x = 28

x = 28/5

x = 5.6

Get m<QRS

Recall that <QRS = 10x - 1

<QRS = 10(5.6) - 1

<QRS = 56-1

<QRS = 55 degrees

Working at papa rons pizza you make 30 per shoft plus 3 per pizza you deliver. If you worked gor bombinoes you eould make 20?Per shift snd 4 per pizza you delivers. How many pizzas do you have to deliver to earb the same amount of money

Answers

Answer: 10 pizzas

Step-by-step explanation:

To answer this you need to equate the formulas of the money earned from both pizzerias.

Assume number of pizzas is x:

Papa rons:

= 30 + 3x

This is the amount one gets for delivering a certain number of pizzas

Bombinoes

= 20 + 4x

Equate them:

30 + 3x = 20 + 4x

30 - 20 = 4x - 3x

x = 10

10 pizzas would earn you the same amount of money.
