A farmer was interested in determining how many grasshoppers were in his field. He knows that the distribution of grasshoppers m

ay not be normally distributed in his field due to growing conditions. As he drives his tractor down each row he counts how many grasshoppers he sees flying away. After several rows he figures the mean number of flights to be 57 with a standard deviation of 12. What is the probability of the farmer will count 52 or fewer flights or 60 or more flights on average in the next 40 rows down which he drives his tractor?

Solve the system of linear equations by using the elimination method: <br> 4x+ y = 36<br> 8x- y = 60
katrin [286]

Answer:

(8,4)

Step-by-step explanation:

y and -y cancels out leaving you with "12x=96"

that simplifies to "x=8"

Then you substitute 8 into the "x" from either equation and y should equal 4

Z=a/b+c/d solve for A
PilotLPTM [1.2K]

Answer: a=\frac{b(zd-c)}{d}

Step-by-step explanation:

Having the following equation given in the exercise:

z=\frac{a}{b}+\frac{c}{d}

You can solve for "a" following this procedure:

1. You can apply the Subtraction property of equality and subtract \frac{c}{d} from both sides of the equation:

z-(\frac{c}{d})=\frac{a}{b}+\frac{c}{d}-(\frac{c}{d})\\\\z-\frac{c}{d}=\frac{a}{b}

2. Now you must subtract the terms on the left side of the equation. Notice that the Least Common Denominator is "d". Then:

\frac{zd-c}{d}=\frac{a}{b}

3. Finally, you can apply the Multiplication property of equality and multiply both sides of the equation by "b". So, you get:

(b)(\frac{zd-c}{d})=(\frac{a}{b})(b)\\\\a=\frac{b(zd-c)}{d}

A sphere and a cone have the same volume each figure has a radius of 3 inches what is the height of the cone
dem82 [27]
Volume of the sphere = 4/3πr³
Volume of the sphere = 4/3 (π) (3)³
Volume of the sphere = 36π

Volume of the sphere = Volume of the cone

36π = 1/3π(3)²h
36π = 3πh
h = 36π ÷ 3π
h = 12

----------------------------------------------------------
Answer: The height is 12 inches.
