Answer:

The answer is "His score changed by 290"

Step-by-step explanation:

2*30 = 60

350 points gained minus the 60 for the spaceships equals 290 points.

He only gained 290 points.

Answer: y= -3x

Step-by-step explanation:

Use the slope-intercept form to find the slope.

m = −3

To find an equation that is parallel to y = −3x + 2, the slopes must be equal. Using the slope of the equation, find the parallel line using the point-slope formula.

(0,0)

m = −3

Using the point-slope form

y − y1 = m (x − x1), plug in

m = −3, x1 = 0, and y1 = 0.

y − (0) = (−3) (x−(0))

Solve for y

y = −3x

Answer:

y=3x+3

Step-by-step explanation:

(2,9)

x=2

y=9

-Slot these numbers into the equation y=mx+c

-Solve for c

y=3x+c

9=3(2)+c (We have substituted y for 9 and x for 2)

-Solve

9=6+c

(rearrange)

c+6=9

c=9-6

c=3

We have found our y-intercept (c)

Add this value into the original equation (replace the other y-intercept with your new value)

y=3x+3

Answer:

m = 11/9

Step-by-step explanation:

m = (y2 - y1) / (x2 - x1)

= (-7 - 4) / (-3 - 6)

= -11/-9

= 11/9

Answer:

Angle 5 would be 119 degrees.

Step-by-step explanation:

This is because the angle that is 61 degrees and angle 5 are both supplementary angles. Supplementary angles would add up to 180 degrees and would lie on the same side of the line. So 180 minus 61 is 119.

Answer:

y = 4x - 17

Step-by-step explanation:

1.  (y - y1)=m(x - x1)      point-slope formula:  slope = 4

2.  (y - 3) = 4 (x - 5)     substitute x and y values:  (5, 3)

3.  y - 3 = 4x - 20        simplify

4.  y = 4x - 20 + 3       rearrange

5.  y = 4x -17               solve

Answer:

The expected number of red balls in the sample is 1.2857.

Step-by-step explanation:

The balls are chosen without replacement from the sample, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The expected value of the hypergeometric distribution is:

[tex]E(X) = \frac{nk}{N}[/tex]

3 red balls in the sample:

This means that [tex]k = 3[/tex]

3 balls are drawn:

This means that [tex]n = 3[/tex]

Total of 3 + 4 = 7 balls:

This means that [tex]N = 7[/tex]

What is the expected number of red balls in the sample?

[tex]E(X) = \frac{nk}{N} = \frac{3*3}{7} = 1.2857[/tex]

The expected number of red balls in the sample is 1.2857.

Answer:

2069 grams

Step-by-step explanation:

Assume that the box itself is massless so the weight is only due to the spheres only. Calculate the volume of a solid sphere of radius 3 in:

Vout = (4/3)pi(3^3) = 36pi in^3

Now calculate the volume of a solid sphere of radius 2 in:

Vin = (4/3)pi(2^3) = (32/3)pi in^3

To calculate the volume of the hollow sphere, subtract Vin from Vout:

Vnet = Vout - Vin = (76/3)pi

Since the density of the plastic is 3.25 g/in^3, the mass of each hollow sphere is

m = (density) × Vnet = (3.25 g/in^3)×(76/3)pi

= 258.7 g

Since there are 8 spheres in a box, the total weight of the box is

M = 8m = 2069 grams
