Answer:
- - 127/7 or - 18 1/7
- - 100/7 or - 14 2/7
- -73/7 or -10 3/7
- -46/7 or - 6 4/7
- -19/7 or - 2 5/7
- 8/7 or 1 1/7
Step-by-step explanation:
<h3>Given </h3>
- AP with the first term of -22 and eighth term of 5
<h3>To find </h3>
<h3>Solution</h3>
<u>AP formula:</u>
<u>Using the given points we find the common difference:</u>
a₁ = -22 and a₈ = 5
- a₈ = a₁ + 7d
- 5 = -22 + 7d
- 7d = 5 + 22
- 7d = 27
- d = 27/7
<u>Now the missing terms:</u>
- a₂ = -22 + 27/7 = - 127/7 or - 18 1/7
- a₃ = -22 + 2(27/7) = - 100/7 or - 14 2/7
- a₄ = -22 + 3(27/7) = -73/7 or -10 3/7
- a₅ = -22 + 4(27/7) = -46/7 or - 6 4/7
- a₆ = -22 + 5(27/7) = -19/7 or - 2 5/7
- a₇ = -22 + 6(27/7) = 8/7 or 1 1/7
Answer:
The average life of the mice that are placed on this diet is less than 40 months.
Step-by-step explanation:
Consider the provided information.
When 40% of the calories in their diet are replaced by vitamins and protein. Is there any reason to believe that μ < 40.
The null and alternative hypothesis are:
64 mice that are placed on this diet have an average life is 38 months with a standard deviation of 5.8 months.
Therefore,
Use the formula:
Substitute the respective values in the above formula.
Now using the table
The p value is smaller than 0.05 so reject the null hypothesis.
Therefore, the average life of the mice that are placed on this diet is less than 40 months.
The first one is 35 x 3 = 105 and 10 x x = 10x
So 105=10x
