Answer:
Step-by-step explanation:
Put the xs together
move the 274 to the other side, and that will be the
you need and
so square root 26 is 5.09, so about 5 when rounded
and square root 22 is 4.69, so about 4.7 when rounded
so
becomes
Answer:
2:29:32
Step-by-step explanation:
time = distance/speed= 162mi/65
=162/65 =2.49231
=2 hours 29 minutes 32 seconds
=02:29:32 (hh:mm:ss)
Hope this helps!
Answer: 24.67 ≤ μ ≤ 27.33
Step-by-step explanation:
From the information given: n = 81 students, Sample mean (x bar) = 26 and sample standard deviation (s) = 6.
Since the population standard deviation in unknown we use the student t distribution to estimate the mean. The mean is estimated as follows:
X bar - t (∝/2, n-1) x s/sqrt n ≤ μ ≤ X bar + t (∝/2, n-1) x s/sqrt n
Degrees of freedom, df = n - 1 = 81 - 1 = 80
∝ = 100 - 95 = 5% = 0.05 thus ∝/2 = 0.025
From the t distribution t (0.025,80) = 1.990
Substituting into the formula:
26 - 1.990 x 6/sqrt 81 ≤ μ ≤ 26 + 1.990 x 6/sqrt 81
24.67 ≤ μ ≤ 27.33
Answer:
The answer is 0.3^2 x 10 = the last number to get 0.9
then 0.9^2 = 0.81 x -10 = 8.1 the actual jump = + 1
We go back 1 places before to do missing sum
so that 0.3 x 1 = 0.3 x -9 = -2.7
Therefore the +1 numbers are decreasing from 10 to -10 then increasing in negative value from -10 to -9 etc.
