Based on these results, which is the most reasonable
balls she will have blocked after 8 games?
A 96
B 32
C 72
D 56

Answers

Answer:

theanswer is D.72

Step-by-step explanation:

this.is because she blocked 36 balls in the first 4 games

As per the given data, it can predict that after 8 games the number of blocks would be 72 balls. Option c is correct.

Given that,
Based on these results, which is the most reasonable balls she will have blocked after 8 games is to be determined.

What is average?

The average of the values is the ratio of the total sum of values to the number of values.

Here,
Average balls blocked in 4 games = 8 + 12 + 9 + 7 / 4 = 36 / 4
                                                          = 9
For the 8 games the number of ball blocked would be  = 8 × 9 = 72

Thus, as per the given data, it can predict that after 8 games the number of ball blocks would be 72 balls. Option c is correct.

has a y-intercept of (0,2) and passes through the point (3,128)

Answers

Answer:

y = 42x + 2

Step-by-step explanation:

The equation of a line is expressed as y = mx+b

Slope = y2-y1/x2-x1

Slope = 128 - 2/3-0

Slope m = 126/3

Slope = 42

Since the y intercept is (0, 2), hence b = 2

Get the equation;

Recall that y = mx+b

y = 42x + 2

This gives the required equation

The diameter of a planet is about 25,660 mi. The diameter of the planet's moon is about 35% of the diameter of the planet. What percent of the volume of the planet is the volume of its moon?
The volume of the planet's moon is % of the volume of its planet.
(Round to the nearest whole number as needed.)

Answers

Answer:

4%

Step-by-step explanation:

Volume of sphere

v = (4/3)πr^3

Volume moon/ volume planet

We don't actually need the numeric value of the radius

just the 35% ratio

Radius of moon = .35 radius of planet

Vm/ Vp = (4/3)π(.35r)^3 / (4/3)π(r)^3

Cancel like terms

Vm / Vp = .35^3

Vm / Vp = 0.042875

Expressed as a percentage

Vm / Vp = 4.2875%

Rounded

Vm / Vp = 4%

A bus departed from New York at 11 pm with 44 passengers. An hour later, a few passengers got off at New Jersey. The number of passengers who boarded the bus at New Jersey were twice the number of passengers who got off the bus. If the bus has 50 passengers now, how many passengers got off at New Jersey?

Answers

Answer:

6 got off at NJ

Step-by-step explanation:

if u write an equation it would be 44-x+2x=50. -x+2x=x so the equation would now be 44+x=50. If you subtract both sides by 44, it would be x=6. x was the number of people that got off at NJ so 6 people got off there.

What is the value of x ?

Answers

Answer:

x = 9°

Step-by-step explanation:

The full arc of the angles equals 360°. So, we can subtract all of the measures of angles we are given from the total 360 to find the value of x.

We can add the given angles together and subtract the sum from 360 as well.

73 + 63 + 89 = 225

This means the measure outside 15x is a combines 225°.

Now, subtract the known measures from our total, 360.

360 - 225 = 135

The unknown, or 15x, is equal to 135°.

15x = 135

Solve this like a normal equation. Divide both sides by 15 to isolate x and solve for the variable.

[tex]\frac{15x}{15}[/tex] = [tex]\frac{135}{15}[/tex]

x = 9

x is equal to 9°.

We can check by adding all our values together again to see if they amount to 360°.

73 + 63 + 89 + 15(9) = 360

360 = 360

The equation is correct, so we can be sure that we are right.

The answer is x = 9°.
