Answer:
Hence the degrees of freedom are associated with the critical value is 25.
Step-by-step explanation:
Using two independent samples, two population means are
compared to determine if a difference exists, the population standard deviation is equal.
sample size 1 = 
= 15 and sample size 2 = 
= 12
since, population standard deviations are equal, required degrees of freedom
Answer:
for what?
Step-by-step explanation:
Answer:
q = 16
Step-by-step explanation:
3(q - 7) = 27
3q - 21 = 27
3q = 27 + 21
3q = 48
q = 48/3
q = 16
Answer: 12 days
Step-by-step explanation:
For us to know the number of days whereby Julie will have both basketball and track practice, we've to find the lowest common multiple of both 6 and 4. This will be:
Multiples of 4 = 4, 8, 12, 16, 24.
Multiples of 6 = 6, 12, 18, 24, 30.
The lowest common multiple is 12. Therefore, she'll have basketball and track practice in 12 days
The force needed to keep the cart at rest is 149.022 pounds
<h3>Force and Motion</h3>
Given Data
- Weight of cart = 200 pounds
The force needed to keep the cart at rest is the vertical component of the resultant force, hence we have
Fy = Mg sin θ
Substituting our given data we have
Fy = 200 sin 40
Fy = 200 *0.74511
Fy = 149.022 pounds
