Answer:
The answer is interest. Good luck to ya.
Step-by-step explanation:
Y= -6 because we eliminated 3x, subtracted 5-2 and -2-16. that gave us 3y=-18. divide by 3 on both sides.
A + j = 360
51.99a + 26.99j = 15591.40
a + j = 360
a = 360 - j
51.99(360 - j) + 26.99j = 15591.40
18716.4 - 51.99j + 26.99j = 15591.40
18716.4 - 25j = 15591.40
-25j = -3125
j = 125
a + (125) = 360
a = 235

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:
–13
Step-by-step explanation:
<h2>—Math </h2>
h(x) = –x –4
h(x) = 9
–x –4 = 9
–x = 9 + 4
–x = 13
x = –13
