899$ is the y intercept because that is your starting value. Then, 65 is your slope. (Rise 65, run 1). After 24 months, the total cost will be 2459$. This is because 24 • 65 = 1560. This is your total cost of phone service. Then, you need to add the phone. 1560 + 899 = 2459. So you total cost is 2459.
Answer:
The distribution of sample means will form a normal distribution
Step-by-step explanation:
1) a. 15% decrease
2) a. $79.20
3) b. 14.3% increase
4) a. $4.68
#1 explanation:
1435 - 1220 = 215
215/1435 = 0.1498
0.1498 x 100 = 14.98 = 15%
#2 explanation:
220 x 0.6 = 132
220-132=88
88 x 0.1 = 8.8
88-8.8 = 79.2 $
#3 explanation:
32-28=4
4/28=0.1428
0.1428 x 100 = 14.28 = 14.3%
#4 explanation:
275 x 0.15 = 41.25
275-41.25 = 233.75
233.75 x 0.02 = 4.675 = 4.68 $
Answer:
r=3
Step-by-step explanation:
Simplify the expression
16-2r=3r+1
isolate r by adding 2r to both sides
16=5r+1
isolate the numbers by subtracting 1 from both sides
15=5r
divide both sides by 5 to completely isolate r
r=3
Area = 285mm²
Length = 18mm
We can find the width by dividing the area by the length.
approximately.
2(18) + 2(15.8) = 67.6mm
