Answer:
Step-by-step explanation:
d=4 miles=4×1760 yards=7040 yards=7040×3 ft
number of lights=21120 ft
number of lights=21120/145 +1≈145.7+1=146+1=147 lights
Answer:
a.y=-x½+5
Step-by-step explanation:
from the above functions ,the highest degree or power is ½ on a.⅓,¼,⅙ are smaller than ½
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The proportion of bruised tomatoes p = 0.08
The null hypothesis is 
The alternative hypothesis is 
The sample size is n = 600
The number of bruised tomatoes from the sample selected is k = 53
The test statistics is z =0.75
Generally the p-value is mathematically represented as
=> 
From the z-table
So
The answer is 42 because they are going by ones 40,41,42

Step-by-step explanation:
<u>Step 1: Set Up Equation</u>
(x + 7)° = (5x - 49)°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract <em>x</em> on both sides: 7 = 4x - 49
- Add 49 on both sides: 56 = 4x
- Divide 4 on both sides: 14 = x
- Rewrite: x = 14
<u>Step 3: Find angle measure</u>
- Define: (x + 7)°
- Substitute in <em>x</em>: (14 + 7)°
- Add: 21°
