Answer:
Yes. Fertilization increases grape yields by more than 5 pounds.
Step-by-step explanation:
Let f-fertilized and o-old(unfertilized)
#First, we use our data to calculate the standard error:
#State both null and alternative hypothesis:
#We determine our degrees of freedom as 87.02(using R), we now compute the t-value as:
Since, the p-value is low, we Reject the null hypothesis. The is enough evidence suggesting that grape yields increase by more than 5 pounds than mean yields of unfertilized grapes.
How many people are in club on third week is 6
Answer:
46,47,48,49,50,51,52,53,54
Step-by-step explanation:
The number of downloads of the high quality version that was made was 600.
<h3>Calculations and Parameters</h3>
This is a great system of equations problem
If we call the number of standard version downloads (S)
The high quality downloads (H).
- For number of songs downloaded: S + H = 910
- For download size: 2.8(S) + 4.4(H) = 3044.
To find S, we can rearrange the first statement to H = 910 - S,
Then we would substitute (910 - S) wherever you see an H in the second equation so that you have only S's in your equation.
Thus:
2.8(S) + 4.4(910 - S) = 3044
2.8S + 4004 - 4.4S = 3044
-1.6S = -960
s = 600

Answer:
To find the circumference, you multiply the radius by 2 and then multiply that by pi (or π). The equation is 2πr
In this case, we already have the radius x 2, which is the diameter. For this circle, the diameter is 12 cm.
The next step is to multiply the diameter, 12 cm, by pi (π is about equal to 3.14)
12 x π ≈ 37.698 cm or 38 cm rounded to the nearest whole number
