3x : 2 = 15

3x = 15 * 2

3x = 30

x = 30 : 3

The average score of all golfers for a particular course has a mean of 61 and a standard deviation of 3.5 . Suppose 49 golfers p
Nadya [2.5K]

Answer:

The probability that the average score of the 49 golfers exceeded 62 is 0.3897

Step-by-step explanation:

The average score of all golfers for a particular course has a mean of 61 and a standard deviation of 3.5

\mu = 61

\sigma = 3.5

We are supposed to find he probability that the average score of the 49 golfers exceeded 62.

Formula : Z=\frac{x-\mu}{\sigma}

Z=\frac{62-61}{3.5}

Z=0.285

Refer the z table for p value

p value = 0.6103

P(x>62)=1-P(x<62)=1-0.6103=0.3897

Hence the probability that the average score of the 49 golfers exceeded 62 is 0.3897

consider the exponential function g(x)=100 x (2). which of the following situations could be modeled by the function?
daser333 [38]
The initial value of 100 that doubles over each interval.
without the answer choices, I can only describe it and give you an example of the graph. 
I'm assuming the function is 100*(2)^x because if it is as listed it would be a quadratic function with a vertical stretch of 100.

What is the solution set of |-x|=-10?
Airida [17]
There is no solution. Because the absolute value function finds the distance between the number and 0. And length is never negative.

So, |-x| = -10 has no solution.
