Answer:
Step-by-step explanation:
If you have an odd number of consecutive numbers, the middle number should be x. So 7 of them would be written as
(x - 3)+(x - 2) + (x - 1) + x + (x + 1) + (x + 2) + (x+3)
That way all you are left with is 7x because the integers cancel.
That is not your question
You question is
Sum = m+(m + 1) + (m + 2) + (m + 3) + (m + 4) + (m + 5) + (m + 6)
Answer:
Step-by-step explanation:
Jonah sister is 10 years old. Jonah is 8 years younger than twice hos sister age
j = 2s - 8
this is the equation.
You can solve it by substituting in 10 for s, because sister is 10 years old.
SOLUTION:
Case: Hypothesis testing
Step 1: Null and Alternative hypotheses

Step 2: T-test analysis

Step 3: t-test with the significance level

Step 4: Comparing

So tail to reject the null hypothesis. There is enough evidence at a 0.05 level of significance to claim that the mean spent is greater than P127.50.
Final answer:
Yes, there is evidence sufficient to conclude that the mean amount spent is greater than P127.50 per month at a 0.05 level of significance.
Answer:
(c, b)
Step-by-step explanation:
Add the coordinates together and divide by 2
x coordinates: 2c + 0 = 2c, divided by 2 = c
y coordinates: 0 + 2b = 2b, divided by 2 = b
Answer:
1 5/12
Step-by-step explanation:
4 1/4- 2 5/6= 1 5/12
Also 1 5/12+ 2 5/6= 4 1/4
