Player 3 is more likely to hit the ball than Player 2 because P(Player 3) > P(Player 2)
Question 13(Multiple Choice Worth 2 points)

Answers

Answer:

Player 3 is more likely to hit the ball than Player 2 because P (Player 3) > P (Player 2).

Step-by-step explanation:

The true statement about the probability when the softball players discussed their batting averages after a game is Player 3 is more likely to hit the ball than Player 2 because P (Player 3) > P (Player 2). The likelihood of randomly selecting a terrier from the shelter is equally likely and unlikely as it's 50%.

The graph shows the number of hours that Tammy spends typing for work, x, and the amount of pay that she earns, y.

On a graph titled Tammy's Pay, number of hours is on the x-axis and pay in dollars is on the y-axis. A line goes through points (2, 18) and (8, 42).

What does the y-intercept represent?

Answers

Answer: The y-intercept is the initial amount Tammy earns.

Step-by-step explanation:

Always remember that for graphs, the y-intercept is the initial amount. In this case, it would be the initial amount or the very first amount Tammy earns. If the line goes through the origin (0,0), that means that Tammy earns $0.00 for 0 hours of working.

A pole that is 3.2m tall casts a shadow that is 1.14m long. At the same time, a nearby tower casts a shadow that is 39.75m long. How tall is the tower? Round your answer to the nearest meter.

Answers

Answer:

112 meters

--------------------------------

The heights and shadows are proportional since they form similar triangles.

Set equal proportions and solve for the missing length:

H/h = S/s, where H and h represent heights, S and s - shadows.H/3.2 = 39.75/1.14H = 3.2*39.75/1.14H = 112 (rounded)

Answer:

112 meters

Step-by-step explanation:

3.2/1.14 = x/39.75

3.2/1.14 = 2.81

2.81 * 39.75 = 111.57 = 112

Kirk, a professional golfer, had an average score last season of 75 points. This season, his average score has been 87 points. What is the percent of increase in Kirk's average score?____%

16 percent of increase

The percent of the increase in Kirk's average score is 12%

Let the total score be 100

We know,

Percent = [tex]\frac{part}{total}[/tex] × 100

Percentage of Kirk's score in last season:

[tex]\frac{75}{100\\}[/tex]×100 = 75%

Percentage of Kirk's score this season:

It says that Haley and Greg sold popcorn for 3 hours, and in that process, Haley sold 15 and Greg sold 9. Each of these popcorn boxes costs $2.

First, we will have to add the number of popcorn boxes each one had in order to find the total. We get

(15 + 9)

Then, we can see that each box costs $2. Multiply the number of popcorn boxes by 2 and use the distributive property.

(15 + 9)*2

= (15*2 + 9*2)

Next, we will need to divide by the number of hours to get how much Haley and Greg sold per hour.

(15*2 + 9*2)/3

D. 324 sq. in.

Answers

Answer: B. 54 sq. in.

Explanation:
In order to use the formula of 6s we first need to find the surface area of one side. To do this we just need to do 3^2 or 3•3. After doing this you’ll get 9 and so now you can do 6s with s being equal to 9. 6•9 equals 54

The pharmacist has a 2.8 L bottle of cough syrup. If she fills a bottle that is 1,200 ml, how many ml of cough syrup does the pharmacist have left?

160 ml
400 ml
1,600 ml
4,000 ml

Answers

Answer: 1,600 ml

Step-by-step explanation:

You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).

2,800 ml - 1,200 ml = 1,600 ml

I hope this helps :)

Answer: 1,600 mL

Step-by-step explanation:

1. convert the 1,200 mL to L, which is 1.2 L.

2. Subtract that value from 2.8 L, equaling 1.6 L

3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.

number of ounces of trail mix the

A) 15 ounces
B) 9 ounces
C) 68 ounces
D) 420 ounces
Explain your answer step by step!

Answers

Answer:

The answer would B) 9 OUNCES

Step by step

The mountain climber eats 61.4 ounces of the trail mix in 7 days. We need to know how much he eats in just one day so we would dived.

[tex]61.4 \div 7 = 8.7714[/tex]

So now we know that each day he ate 8.7714 ounces of trail mix in a day. But when we look at the options this answer is not there so we have to round the number. When we're rounding we have to look at the second number if it is 5 and under then we round down but if it is 5 and up we round up. In our case the second number is 7 so we round up which would give us 9. Therefore the answer is B

61.4 ÷ 7 = 8.77

8.77 rounds to 9 ounces.
