Answer:
0=0
Step-by-step explanation:
50x+34=50x+34
50x=50x
50x - 50x = 50x - 50x
0=0
Answer:
often one of the first strategies that students learn when solving problems. This is a flexible strategy that is often used as a starting point when solving a problem, and can be used as a safety net, when no other strategy is immediately obvious.
Step-by-step explanation:
So given l = x+5 and w = x
area represented by equation x^2 +5x = 300
x^2 +5x -300 =0
(x+20)(x-15)=0
x+20 =0
x = -20
x-15=0
x=15
so from these result the width of rectangle equal 15 inches and the length of rectangle equal 20 inches
Answer:
e) (3.77%, 8.70%)
95% confidence interval for the percentage of all medical students who plan to work in a rural community
(3.83% , 8.69%)
95% confidence level for the population proportion who blame oil companies for the recent increase in gasoline prices
(0.406 , 0.454)
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given random sample size 'n' = 369
Sample proportion

95% confidence intervals are determined by


(0.0623 - 0.0246 , 0.0623 + 0.0246)
(0.0383 , 0.0869)
(3.83% , 8.69%)
95% confidence interval for the percentage of all medical students who plan to work in a rural community
(3.83% , 8.69%)
<u>Step(ii):-</u>
Given 43% of those polled blamed of companies the most for the recent increase in gasoline prices
sample proportion 'p' = 0.43
Given Margin of error (M.E) = 0.024
95% confidence intervals are determined by


(0.406 , 0.454)
<u>Final answer</u>:-
95% confidence level for the population proportion who blame oil companies for the recent increase in gasoline prices
(0.406 , 0.454)
Here are the steps to solve:
1. Combine 5x and 3x Now you have 8x -4 = 10
2. Get x alone by adding 4 (But be fair so you have to do it on both sides)
Now you have 8x = 14
3. Divide both sides by 8
x = 8/14 (Which is 0.57142857)
