Answer:
C), or y = 200(1.18)^x, because we have 200 bacteria to start with and 1.18 because if you multiply something by 1.18 that is essentially 118% more than the number, or 18% more than the number.
Hope this helps!
Answer:
$1226.78<x<$1301.22
Step-by-step explanation:
The formula for calculating confidence interval is expressed as;
CI = xbar ± z×(s/√n)
Given
Mean (xbar) = $1264
z is the z score at 90% CI = 1.645
s is the standard deviation = $150
n is the sample size = 44
Substitute
CI = 1264±1.645(150/√44)
CI = 1264±1.645(150/6.63)
CI = 1264±1.645(22.624)
CI = 1264±37.22
CI = (1264-37.22, 1264+37.22)
CI = (1226.78, 1301.22)
Hence the confidence interval of the mean is $1226.78<x<$1301.22
Answer:
x = 77, x = -77
Step-by-step explanation:
|x| – 17 = 60
Add 17 to each side
|x| – 17+17 = 60+17
|x| = 77
The absolute value equation has two solutions, one positive and one negative
x = 77, x = -77
