Answer:
1. It should be 100 centimeters but since you don't have it, or if you do, then add that, then the range of centimeters should be 54 if you have it, or if you have 50 then add that
2. also you go down to the persons answer, then look for that crown, then click it.
Step-by-step explanation:
54 miles because Quinn runs 9 miles every week and 9x6=54
Answer:
x=1
Step-by-step explanation:
-8x+2(4+2)=4
-8x+2×6=4
-8x+12=4
-8x=4-12
-8x= -8
we multiply both sides with (-1) to get a positive number in the x side
-8x= -8 / ×(-1)
8x=8
x=8/8
x=1
Answer:
18 cm.
Step-by-step explanation:
There are four sides on a square, and each side has the same measure as the other three. So, if one side measures 4.5 cm, four sides would be 4 * 4.5 = 4.5 + 4.5 + 4.5 + 4.5 = 9 + 9 = 18 cm
Hope this helps!
Answer: 0.8413
Step-by-step explanation:
population mean = 3
population variance = 0.03
sd (standard deviation) = √0.03
Let x = sample mean
x has a mean of 3 and sd of √0.03/√3 = √0.01 = 0.1
And we can aprox the sample mean distribution using a normal distribution
Note: this approximation maybe is not so good (n = 3)
with mean = 3 and sd = 0.1
z = (x-3)/0.1 has a standard normal distribution
P(x<3.1) = P(z<(3.1-3)/0.1) = P(z<1) =0.8413
