Answer:
l=95
Step-by-step explanation:
Perimeter is all the sides add up. So the equation if you know two of the sides, it should be: 338=(2*74)+(2*l)
Answer:
Step-by-step explanation:
the perimeter is 2w plus 2l
so 338 = 74(2)+2l
338 = 148+2l
190=2l
l=95
your length would be 95 m
Answer:
-5
Step-by-step explanation:
Parallel lines have the same slope, so it would just be -5

Answer:
D. The 95% confidence interval ranges from 42.78 to 47.22 hours.
Step-by-step explanation:
In a sample of 50 households, the mean number of hours spent on social networking sites during the month of January was 45 hours. In a much larger study, the standard deviation was determined to be 8 hours.
Here,
n = sample size = 50,
μ = mean = 45,
σ = standard deviation = 8,
We know that, confidence interval will be,
For a confidence interval of 95%, we use z = 1.96, putting the values
Answer:
Step-by-step explanation:
4(x+1)²=100
(x+1)²= 5²
(x+1)²- 5² = 0
(x+1-5)(x+1+5) = 0 by identity : a² - b ² = (a - b) (a+b)
(x - 4 ) (x+6) =0
x - 4 = 0 or x+6 = 0
x = 4 or x = - 6
