I’m not sure, but I believe the answer is C. (-3.4, -2). The reason why is because (-7/2, -2) makes absolutely no sense, (-3, 0) does not make sense either since the middle’s Y axis is -2, And for it to be (-3, -2), the X axis number would have to be directly on the “-3” line.

While bowling, Sarah made 5 strikes out of her last 18 frames. David made 9 strikes out his last 25 frames. What is the probabil
Alla [95]

Answer:

1/10 or 0.1

Step-by-step explanation:

Probability of occurrence of any event = number of favorable event by total /number of occurrence of event.

For Sarah

Given Number of frames = 18

Number of strikes made by her = 5

Therefore by using the above formula to get the probability of striking by Sarah will be 5/18.

__________________________________________________

For David

Given Number of frames = 25

Number of strikes made by him = 9

Therefore by using the above formula to get the probability of striking by David will be 9/25.

__________________________________________________

Since the event of Sarah and David are mutually independent i.e occurrence of one event does not impact the occurrence of other event.

Probability of occurrence of two mutually independent A and B event with Probability P(A) and Probability P(B) is given by P(A) * P(B).

Therefore probability that they both get a strike on their next frame are mutually independent event with probability 5/18 and 9/25 will be calculated by 5/18 * 9/25 = 1/(2*5) = 1/10.

A survey of 5,913 American adults concludes that 53% of them prefer Captain America to Ironman. Find the Margin of Error. Type y
Virty [35]

Answer:

1.3%

Step-by-step explanation:

Phat = 0.53

1 - phat = 1 - 0.53 = 0.47

Sample size, n = 5913

Assume the confidence level = 95%

Zcritical at 95% = 1.96

Margin of Error = Zcritical * √(phat(1 -phat)) / n

Margin of error :

1.96 * √((0.53 * 0.47) / 5913)

1.96 * 0.0064905

= 0.0127215

= 0.0127215 * 100%

= 1.272%

= 1.3%

List the steps to solve the following equation: 5x - 6 = 44 then solve x
Dafna1 [17]

Answer:

1. Add 6 to both sides, cause that is the inverse of subtraction, so you get 5x = 50 as 6 cancels 6 out.

2. Divide 5 from both sides and get x = 10
