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.
Answer:
The area of the sector is 17/2 π
Step-by-step explanation:
pi = π
To solve this problem we first have to find the fraction that corresponds to this angle of the total, for this we must divide the angle that they give us by 2π radians, since that is the angle of a circle
(17π/9 rad) / (2π rad) = 17/18
Now we multiply the area of the circle by this fraction and we will obtain the area of the sector that we want
9π * 17/18 = 17/2 π
The area of the sector is 17/2 π
Ans:
TV = QS
Step-by-step explanation:
Because TV are parallel to QS
so TV is equals to QS
<h3>
Answer:</h3>
0.225
<h3>
Step-by-step explanation:</h3>
The mnemonic SOH CAH TOA reminds you of the definition of the tangent of an angle.
... Tan = Opposite/Adjacent
The side opposite angle C is AB. The side adjacent to angle C is BC. Then ...
... tan(C) = AB/BC = 18/80 = 0.225
Ok so
so firs what we do is
1150/12 and ignor remainder
95 and remainder is 10
therfor we have 95 trucks full and 10 cars in the last truck
