2x + 18 and 4x - 14 are corresponding angles...they are equal
2x + 18 = 4x - 14
2x - 4x = -14 - 18
-2x = - 32
x = -32/-2
x = 16
so the measure of 4x - 14 = 4(16) - 14 = 64 - 14 = 50
and 4x - 14 and y are supplementary angles that add up to 180 degrees
so 50 + y = 180.....y = 180 - 50....y = 130 <==
Let's say we have the fraction 
For instance, in the case of the fraction: " 1/2" ; the denominator is ' " 2 " . If the denominator is 2, we must divide 2 by our numerator which is 1 so we will create a divison problem and it will be 1 ÷ 2 = 0.5

Answer:
$2948 and $4030
Step-by-step explanation:
The CI is sample mean +/- s/sqrt(n)
t(0.95,df=63 critical values are |t|>1.669
90% CI is 3489+/-1.669*(2595/8) since sqrt(64)=8
the interval is 541.38
round to 541
the interval is 3489+/-541
($2948,$4030) is the 90% CI for the mean.
Answer:
34
Step-by-step explanation:
12(3)-2
36-2
34
To solve this problem, we use the formula:
z = (x – u) / s
where z is the z score value which can be obtained from
the tables, x is the sample value, u is the mean = 6.3 min, and s is the std
dev = 2.2 min
at P value = 0.90, the z = 1.28, finding for x:
x = z s + u
x = 1.28 * 2.2 + 6.3
x = 9.116
at P value = 1.0, the z = 3.49, finding for x:
x = z s + u
x = 3.49 * 2.2 + 6.3
x = 13.978 ~ 14
Therefore the longest 10% calls last about 9.1 minutes to
14 minutes
