Mrs. Gilbert is interested in determining how many students spend 4 or more hours doing homework each week. She asks every student who earned Honor Roll for the first semester. Is her survey biased or unbiased?

A. biased, because she didn't ask random students
B. unbiased, because she asked every student on honor roll
C. biased, because she only asked students on honor roll
D. unbiased, because first semester is over

Answers

Answer 1

Answer:

C. Biased, because she only asked students on honor roll.

Step-by-step explanation:

Since Mrs. Gilbert's goal was to find how many students that spent >4 hours and not how many students that earned Honor Roll that spent >4 hours, the data is biased. Choose C.

John has $5.05 in quarters and nickels in his pocket. If John only has 25 coins in his pocket, how many of the coins are quarters?

Answers

Answer:

Step-by-step explanation:

q+n=25

n=25-q

25q+5n=505, using n=25-q in this equation gives you

25q+5(25-q)=505

25q+125-5q=505

20q+125=505

20q=380

q=19

So 19 of the coins are quarters.

I'm stuck on a math question. "A submarine is descending to examine the seafloor 2100 feet below the surface. It takes the submarine 2 hours to make this descent. Write an equation to represent the relationship between the submarines elevation and time."

Answers

Answer:

-1,050

Step-by-step explanation: This is quite simple first we know that 2,100 is negative(-2,100) because it is descending/going down. So now we know that we can divide -2,100 by 2 which sums up to 1,050. But we are going to have to add a negative sign due to the fact that if the two integers you are dividing are opposite signs it would be negative. So if you add a negative sign to 1,050 it would be -1,050. Just to keep in mind that opposites make negative when dividing I will put the integer rules below.

Answer:

The answer is -1,050.

Step-by-step explanation:

An equation to represent the relationship between the submarines elevation & time would be y=-1,050x. Since we know that in two hours the submarine can reach 2,100 feet below the surface we need to figure out how long the submarine can reach in 1 hour. So we do 2,100/2 which equals 1,050. And since the submarine going below, it turns into -1,050.

Actually Welcome to the Concept of the Parallel lines and Transvell.

We here are going to use the concept of Corresponding angles, co- interior angles and linear pair also Adjacent angles.

hence, we get as,

1.) x = 60° , y = 60°.....(vertically opposite angles)

2.) x = 120° , y = 120°

3.) x = 105° , y = 75°

4.) x = 140° and y = 40°

All are above done.

solve for x and y 5x + 3y=35, 2x+4y=28​

Answers

The answer would be:

y = 5

x = 4

Answer:

Step-by-step explanation:

Let's solve your system by substitution.

5x+3y=35;2x+4y=28

Step: Solve 5x+3y=35 for x:

5x+3y=35

5x+3y+−3y=35+−3y(Add -3y to both sides)

5x=−3y+35

5x/ 5 = −3y+35/ 5  (Divide both sides by 5)

Step: Substitute  −3/ 5 y+7 for x in 2x+4y=28:

2x+4y=28

2( −3/ 5 y+7)+4y=28

14/ 5 y+14=28   (Simplify both sides of the equation)

14/ 5 y+14+−14=28+−14   (Add -14 to both sides)

14/ 5 y=14

14/ 5 y/ 14/ 5 = 14/ 14/ 5

(Divide both sides by 14/5)

y=5

Step: Substitute 5 for y in x= −3/ 5 y+7:

x= −3/ 5 y+7

x= −3/ 5 (5)+7

x=4  (Simplify both sides of the equation)

Answer:

x=4 and y=5
