The true answer is A. all parallelograms are rectangles
Answer:
Interest earned is $8.75
Total amount of money earned = 708.75
Step-by-step explanation:
Principal = 700
Rate = 2.5%
Time = 6 months = 6/12 years = 0.5 years
Interest = PTR/100
= 700x0.5x2.5/100
= 8.75
Total amount = P + I
= 700 + 8.75
= 708.75
W= width
l= 2w= length
Perimeter of a Rectangle Formula
P= 2(l + w)
substitute 2w for l in equation
180= 2(2w + w)
multiply 2 by parentheses
180= 4w + 2w
combine like terms
180= 6w
divide both sides by 6
30 yards= w
LENGTH
2w= 2(30)= 60 yards
CHECK:
180= 30 + 60 + 30 + 60
180= 90 + 90
180= 180
ANSWER: the width is 30 yards and the length is 60 yards
Hope this helps! :)
Step-by-step explanation:
Answer is 1, because, your multiplying 1 12 times, so it is
1*1*1*1*1*1*1*1*1*1*1*1=1
even if it was 1 to the power of 100, it's still going to be 1, if the base number is 1, then exponent can be any number and still getting 1.
Answer:
16% probability that a randomly chosen U.S. adult sleeps more than 8.7 hours per night
Step-by-step explanation:
The Empirical Rule(Standard Deviation) states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 7.5
Standard deviation = 1.2
Using the Standard Deviation Rule, what is the probability that a randomly chosen U.S. adult sleeps more than 8.7 hours per night?
8.7 = 7.5 + 1.2
So 8.7 is one standard deviation above the mean.
By the Empirical Rule, 68% of the measures are within 1 standard deviation of the mean. The other 100-68 = 32% are more than one standard deviation from the mean. Since the normal probability distribution is symmetric, 16% are more than one standard deviation below the mean and 16% are more than one standard deviation above the mean(above 8.7 hours)
So, 16% probability that a randomly chosen U.S. adult sleeps more than 8.7 hours per night
