Answer:
20
Step-by-step explanation:
let the number of rounds of golf played for the cost to equal be x.
-It costs $35/ round when the membership of $500 is paid, hence, total annual cost is:
#When membership is not paid, the annual cost is expressed as:
#Since the cost should be equal after x rounds, we equate the two to solve for x:
Hence, Mr Bailey has to play 20 rounds of golf for the cost in both scenarios to be equal.
All sides of a square are the same so if the length of one is is 11 inches, then all of the sides are 11 inches.
To work out the area of a square you multiply the length and the width.
In this case the sum would be: 11 x 11
The answer to that is 121.
So overall, the answer would be 121 inches.
Answer:
Step-by-step explanation:
We want to determine a 98% confidence interval to estimate the true mean shear strength of anchor bolts.
Number of sample, n = 78
Mean, u = 4.25
Standard deviation, s = 1.3
For a confidence level of 98%, the corresponding z value is 2.33.
We will apply the formula
Confidence interval
= mean ± z × standard deviation/√n
It becomes
4.25 ± 2.33 × 1.3/√78
= 4.25 ± 2.33 × 0.147
= 4.25 ± 0.34
The lower end of the confidence interval is 4.25 - 0.34 = 3.91
The upper end of the confidence interval is 4.25 + 0.34 = 4.59
b) the confidence interval would still be valid because the number of samples is large(> 30)

Answer:
x = 4/7
Step-by-step explanation:
5/3 x = 20/21
Multiply by 3/5 on each side to isolate x
3/5 *5/3 x = 20/21 * 3/5
x = 20/21 * 3/5
Rewriting the right hand side
x = 20/5 * 3/21
x =4 * 1/7
x = 4/7
