Answer:
22 inches= 1 foot and 10 inches
Step-by-step explanation:
Step 1. change the feet into inches
Step 2. subtract Rudy's height 38 inches from his fathers height 60 inches and you get 22 inches or 1ft and 10 inches
We will use the following formula to work out the confidence interval
Upper limit = μ + z* (σ/√n)
Lower limit = μ - z* (σ/√n)
We have
μ = 79.3
σ = 7.8
n = 12
z* is the z-score for 95% confidence level = 1.96
Substitute these into the formula, we have
Upper limit = 79.3 + 1.96 (7.8/√12) = 83.7
Lower limit = 79.3 - 1.96 )7.8/√12) = 74.9
24: 1,2,3,4,6,8,24
36: 1,2,3,4,6,9,12,36
27:1,3,9,27
7:1,7
C=number of acres of corn
w=number of acres of wheat
total is 180 acres
c+w=180
wants to plant 3 times as many corn as wheat
c=3w
subsitute 3w for c in other
c+w=180
3w+w=180
4w=180
divide boh sides by 4
w=45
sub back
c=3w
c=3(45)
c=135
135 acres of corn and 45 acres of wheat
The answer would be D. (2,2)
Since the scale factor is 1/2, all you have to do is multiply 1/2 by each of x-coordinate and y-coordinate of Q.
Multiplying by 1/2 is the same as dividing by 2, so you divide the x and y coordinates of Q to get the dilation image of Q as (2,2).
