Answer: 1. 7:10
2. 10 blue cans
15 yellow cans.
3. 4 cans of blue paint.
5 cans of yellow paint.
4. 2 blue cans and 3 yellow cans.
Step-by-step explanation:
1. 14 blue paint cans/20 yellow paint cans=
14/20=
7/10 ==> 7:10
2. 4+6 blue cans=10 blue cans
6+9 yellow cans=15 yellow cans.
3. 14-10=4 cans of blue paint.
20-15=5 cans of yellow paint.
4. 10 blue cans/15 yellow cans=
10/15=
2/3 ==> 2:3 ==> 2 blue cans and 3 yellow cans.
Answer:
Step-by-step explanation:
Given that
Group Group One Group Two
Mean 26.00 23.00
SD 2.00 4.00
SEM 0.40 1.21
N 25 11
where group I represents female servers and group II male servers.
We have to calculate confidence interval for 90% for difference in means
The mean of Group One minus Group Two equals 3.00
df = 34
standard error of difference = 0.993
t critical = 2.034 for 90% df 34
Hence confid. interval at 90%
=Mean diff ±2.034 * std error of diff
= (0.98, 5.02)
If the diameter is 16 inches, then its radius is half that, r = 8.
Answer:
it's rational for the second part it is the 1st option and the 4th option
Step-by-step explanation:
Pythagorean theorem
c2 = a2 + b2
71^2 = 43^2 + b2
5041 = 1849 + b2
3192 = b2
b = 56.5 which is answer choice d
