Answer:
95 percent
Step-by-step explanation:
The empirical rule states that approximately 95% of observations will fall within 2 standard deviations of the mean if the population is approximately symmetrical(normal) in distribution.
The interval from 33 to 65 falls within 2 standard deviations of the mean;
49-2(8) = 33
49+2(8) = 65
Thus, 95 percent of data will fall within the interval from 33 to 65
Answer:
the perimeter is 30
Step-by-step explanation:
ok so lets say this
width= x
length= 2x
the area is
A= wl
or
25 = x(2x)
25= 2x^2
5 = x thats the width so we know that if we double that we get the legnth so
the legnth is 10
the perimeter is defined as:
2l +2w =p
insert the width and legnth
2(5) + 2(10) = p
10+ 20= p
p= 30
Answer:
I would say the last one
Step-by-step explanation:
The third works the same way but 46/17 is hard to calculate without a calculator
Answer:
A
Step-by-step explanation:
You know that you can simplify 6/9 because both the numerator (top number) and denominator (bottom number) can be divided by 3. Therefore, you divide them by 3 to get 2/3. 2/3 cannot be simplified anymore. 2/3 is equal to 2/3. Therefore, the answer is A.
