Answer:

4.5 sq. units

Step-by-step explanation:

area = -⅓x³+3/2 x² ] 0 to 3

= -⅓(3)³+ 3/2 (3)² -0

= -9 + 27/2

= -9 + 13.5

= 4.5 sq. units

Let a equal measure of a angle a. The equation 360゚= a + 90゚+ 135゚+ 75゚ represents the sum of the angles in the quadrilateral. F
lina2011 [118]

Answer:

A = 60°

Step-by-step explanation:

First to find the missing angle you add the three known angles,

90 + 135 + 75 = 300

Then, you subtract, 360 - 300 = 60

<h3>So, 360° = 60° + 90° + 135° + 75°</h3><h3 />

What is -x+y=6 in funtion form
lisov135 [29]
To get the function form, the y must be the only variable on one side. So, we need to solve for it.

We have:

-x + y = 6

then we get

y = 6 + x

when we move the x to the other side to get y by itself.

If you have any questions then leave a comment. Good luck!

Last​ year, a person wrote 126 checks. Let the random variable x represent the number of checks he wrote in one​ day, and assume
Arisa [49]

Answer:  The mean number of checks written per​ day  =0.3452

Standard deviation=0.5875

Variance  =0.3452

Step-by-step explanation:

Given : The total number of checks wrote by person in a year = 126

Assume that the year is not a leap year.

Then  1 year = 365 days

Let the random variable x represent the number of checks he wrote in one​ day.

Then , the mean number of checks wrote by person each days id=s given by :-

\lambda=\dfrac{126}{365}\approx0.3452

Since , the distribution is Poisson distribution , then the variance must equal to the mean value i.e. \sigma^2=\lambda=0.3452

Standard deviation : \sigma=\sqrt{0.3452}=0.5875372328\approx0.5875
