Answer:
500
Step-by-step explanation:
First we make an equation to find the score for the bonus round. x is the score for the bonus round .
300 + x = 800
Next we subtract 300 from both sides of the equation
300 - 300 + x = 800 - 300
Which get us
0 + x = 500
x = 500
Her score in the bonus round is 500
Answer: It is not enough evidence to support the researcher's claim.
Step-by-step explanation:
Since we have given that
n = 500

So, the hypothesis are as follows:

So, the z value would be

At α = 0.05
z= -1.64
So, 1.64<-1.33
So, we accept the null hypothesis.
Hence, it is not enough evidence to support the researcher's claim.
Answer:
4. the distance it travled
Answer:
Step-by-step explanation:
Multiply both sides by 7
7x + 9 = 105
7x = 96
x = 96/7= 13 5/7
