Answer:0.09 < 0.6 < 0.7 < 0.8 < 0.99 < 1
Step-by-step explanation:
Answer:
not statistically significant at ∝ = 0.05
Step-by-step explanation:
Sample size( n ) = 61
Average for student leader graduates to finish degree ( x') = 4.97 years
std = 1.23
Average for student body = 4.56 years
<u>Determine if the difference between the student leaders and the entire student population is statistically significant at alpha</u>
H0( null hypothesis ) : u = 4.56
Ha : u ≠ 4.56
using test statistic
test statistic ; t = ( x' - u ) / std√ n
= ( 4.97 - 4.56 ) / 1.23 √ 61
= 2.60
let ∝ = 0.05 , critical value = -2.60 + 2.60
Hence we wont fail to accept H0
This shows that the difference between the student leaders and the entire student population is not statistically significant at ∝ = 0.05
Answer:
4) The square root of 25 is rational
5) pi is irrational
Step-by-step explanation:
To know if the answer is rational or irrational, check to see if they can be turned into a fraction.
Answer: 40 divided by 6 is equal to 6 with a remainder of 4: 40 / 6 = 6 R.
Step-by-step explanation:Start by setting it up with the divisor 6 on the left side and the dividend 40 on the right side like this:
6 ⟌ 4 0
The divisor (6) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:
0
6 ⟌ 4 0
Multiply the divisor by the result in the previous step (6 x 0 = 0) and write that answer below the dividend.
0
6 ⟌ 4 0
0
Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.
0
6 ⟌ 4 0
- 0
4
Move down the 2nd digit of the dividend (0) like this:
0
6 ⟌ 4 0
- 0
4 0
The divisor (6) goes into the bottom number (40), 6 time(s). Therefore, put 6 on top:
0 6
6 ⟌ 4 0
- 0
4 0
Multiply the divisor by the result in the previous step (6 x 6 = 36) and write that answer at the bottom:
0 6
6 ⟌ 4 0
- 0
4 0
3 6
Subtract the result in the previous step from the number written above it. (40 - 36 = 4) and write the answer at the bottom.
0 6
6 ⟌ 4 0
- 0
4 0
- 3 6
4
You are done, because there are no more digits to move down from the dividend. The answer is the top number and the remainder is the bottom number. Therefore, the answer to 40 divided by 6 calculated using Long Division is: 6
4 Remainder
a b and c are all correct answers
