Answer:

0.45

Explanation:

The probability that the rainfall for the year is less than 8 inches is equal to the area under the curve of the probability density function to the left of 8 inches.

I attached a graph with the squares that cover that area in red.

There are 7 complete, or almost complete, red squares and 4 triangles.

For estimation purposes, you can count each triangle as half a square.

Thus, consider 7 + 4/2 = 7 + 2 = 9 squares.

Since the area of each square on the grid is 0.05, the area o 9 squares is:

9 × 0.05 = 0.45

Hence, your estimate of the probability that the rainfall for this year is less than 8 inches is 0.45.

Answer:

Try B) 2x - 3y = -9

Step-by-step explanation:

I plotted the points and started to make each answer into the "y = " formula. The only one that passed through all the points was B) 2x - 3y = -9 which I changed into y = 2x/3 + 3

For this figure what is the value of X? How did you solve this?

Ivanshal [37]

Answer:

x=60

Step-by-step explanation:

This is a parallelogram.

For a parallelogram,

sum of angles in one side is 180.

we know, in a parallelogram,

the consecutive angles are supplementary or

their sum is 180.

So, we get,

x+33+87=180

or, x+120=180

subtracting 120

x+120-120=180-120

or, x=60

Solve the system of equations using the linear combination method. 3x-2y=13 4x+5y=2

Gnom [1K]

Answer:

The solution of the system will be: $x= 3$ and $y=-2$ 

Step-by-step explanation:

The given system of equations is.......

$3x-2y=13................................(1)\\ \\ 4x+5y=2..................................(2)$

Multiplying equation (1) by 5 and equation (2) by 2, we will get........

$5(3x-2y)=5(13)\\ 15x-10y=65...............................(3)\\ \\ and\\ \\ 2(4x+5y)=2(2)\\ 8x+10y=4...................................(4)$

Now, adding equation (3) and (4), we will get.........

$(15x-10y)+(8x+10y)=65+4\\ \\ 23x=69\\ \\ x=\frac{69}{23}=3$

Plugging this $x=3$ into equation (1).........

$3(3)-2y=13\\ \\ 9-2y=13 \\ \\ -2y=4\\ \\ y=\frac{4}{-2}=-2$

So, the solution of the system will be: $x= 3$ and $y=-2$

Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate. Favorite colors Cho

Sloan [31]

Answer:

(A), Nominal.

Step-by-step explanation:

Nominal scale of measurement is used with a type of data when different levels of a particular factor are to be compared. In simple words, the nominal scale is generally used to label the variables. For example, label the eye color as brown, black and other.

In this case the favorite colors can take only labeled names and they are not being used to make the comparison between the colors.

Thus, the correct level of measurement is nominal.

The correct option is (A), Nominal.
