Answer:
x = 3
Step-by-step explanation:
Given
f(x) = - 10x + 45 and f(x) = 15, then equating gives
- 10x + 45 = 15 ( subtract 45 from both sides )
- 10x = - 30 ( divide both sides by - 10 )
x = 3
Answer:
sample size n would be 149305 large
Value of n (149305) is too high, this will be the practical problem with attempting to find this confidence interval
Step-by-step explanation:
Given that;
standard deviation α = 150 min
confidence interval = 99%
since; p( -2.576 < z < 2.576) = 0.99
so z-value for 99% CI is 2.576
E = 1 minutes
Therefore
n = [(z × α) / E ]²
so we substitute
n = [(2.576 × 150) / 1 ]²
n = [ 386.4 ]²
n = 149304.96 ≈ 149305
Therefore sample size would be 149305 large
Value of n is too high, that would be the practical problem with attempting to find this confidence interval
Answer:
<u>7/8 feet</u>
Step-by-step explanation:
In order to add two frctions you need to make their denominator the same,
3/8 can be kept as it is and we can multiply the top and bottom of 1/2 by 4 in order to ger 4/8. Now it is easier to add together,
3/8 + 4/8= <u>7/8</u>
