The Average test score start = 100%
It increases by 10%:
100% = 1
10% = 0.10
1 x 0.10 = 0.1
1 + 0.1 = 1.1
It increases by another 15%
1.1 x 0.15 = 0.165
1.1 + 0.165 = 1.265
Remember to move the place value digit to the right two spaces to make it a percentage
126.5% increase is your answer
hope this helps
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


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


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
Answer:
k=42.5573 and x=0.015699
Step-by-step explanation:
Step: Solve k=35.5x+42for k:
k=35.5x+42
Step: Substitute 35.5x+42 for k in k=991x+27:
k=991x+27
35.5x+42=991x+27
35.5x+42+−991x=991x+27+−991x(Add -991x to both sides)
−955.5x+42=27
−955.5x+42+−42=27+−42(Add -42 to both sides)
−955.5x=−15
−955.5x
−955.5
=
−15
−955.5
(Divide both sides by -955.5)
x=0.015699
Step: Substitute0.015699 for x in k=35.5x+42:
k=35.5x+42
k=(35.5)(0.015699)+42
k=42.5573(Simplify both sides of the equation)

Answer:
254.8
Step-by-step explanation:
Substitute the numbers where the variables are and do the arithmetic.
4c +2b³ = 4(1.2) +2(5³) = 4.8 +250 = 254.8
