The probability that you win first prize and your friend wins second

prize is 5/210

Step-by-step explanation:

Step 1 :

Total number of prizes awarded = 3

Number of people entering the draw = 7

Number of ways to award the prize = 210

We need to find the probability that we win the first and the second prize

Step 2 :

Out of the 3 prizes we need the first and the second. Hence the prize for the first and the second positions are fixed as we do not consider the remaining 5 people to win the prize here.

Hence the remaining number of people who can win the 3rd prize = 5

The number of ways one of them wins the 3rd prize = 5

The total number of ways = 210

Hence the probability of the first 2 prizes fixed and the remaining 3rd awarded to the rest of the 5 people is 5/210

Step 3 :

The required probability 5/210

Which product is positive?<br>

Tresset [83]

Answer:

The last option.

Step-by-step explanation:

When you multiply a negative by a negative it makes a positive number. Therefore, if you multiply an even number of negative numbers, you get a positive product. The other options have an odd number of negative numbers to multiply by that makes them result in a negative product.

Draw and label an example of two parallel lines that are perpendicular to a third line.

lara31 [8.8K]

Euclid used a somewhat different parallel postulate in trying to avoid the notion of the infinite. He observed that when two parallel lines are intersected by a third line, called a transversal, then if you measure two angles formed by these three lines, on the same side of the transversal and between the parallels, they will add to (that is, they will be supplementary). Such angles are called same-side interior angles<span>:</span>

Which residual plots indicate that the original data set has a linear relationship? Check all that apply

VMariaS [17]

Answer: A, B and E

Step-by-step explanation:

A residual values should be equally and randomly spaced around the horizontal axis. If the plot looks like any of the images in C and D, then the data set is probably not a good fit for regression. A non-linear pattern is more appropriate.

Paolo is putting a fence around his pool. The length of the pool is 20 feet, the width is (20 minus x) feet, and the area of the

Diano4ka-milaya [45]

Answer:

The value of x = 5

Step-by-step explanation:

Length of the pool = 20 feet

Width of the pool = (20 minus x) feet

Area of the pool = 300 square feet

Area of a rectangular pool = length × width

300 = 20 (20 - x)

300 = 400 - 20x

Subtract 400 from both sides

300 - 400 = 400 - 20x - 400

- 100 = - 20x

Divide both sides by -20

x = -100/-20

= 5

x = 5

The value of x = 5
