First, find a common denominator. Since both 6, 3, and 4 can be multiplied into 12, that will be or denominator.
1/6 becomes 2/12
2/3 becomes 8/12
and 1/4 becomes 3/12
2/12 + 8/12 = 10/12
The answer is 1 1/12
Answer:
H0: μc ≤ μs Ha :μc > μs
Step-by-step explanation:
The null and alternate hypotheses can be stated as
H0: μc ≤ μs Ha :μc > μs one tailed test
Where
μc = Mean of college students watching movies in a month
μs = Mean of school students watching movies in a month
For one tailed test of α =0.05 the value of Z= ± 1.645
The critical region will be Z > ± 1.645
It is of importance to note that by rejecting the null hypothesis and accepting the alternate hypothesis we are automatically rejecting all values of mean that are greater than 7.1
2208 rounded to the nearest hundred would be 2200 because the number beside 2 is 0 and that makes the number stay the same and everything after it would be 0 so the answer is 2200
Answer:
Step-by-step explanation:
Given
w + 1 = d...........equation 1
d = 3w ...............equation 2
Now putting d = 3w in equation 1
w + 1 = 3w
3w - w = 1
2w = 1
w = 1 / 2
putting w = 1 / 2 in equation 2
d = 1 / 2 * 3
= 3/2
Hope it helps :)
