Answer:

the answer b

Step-by-step explanation:

[surface area]=[area of 4 triangles sides]+[area of square base]

[area of square base]=24*24--------> 576 cm²

[area of one triangles side]

l=slant height

l²=16²+12²-------> l²=400-----------> l=20 cm

[area of one triangles side]=24*20/2--------> 240 cm²

[area of 4 triangles sides]=4*240----------> 960 cm²

[surface area]=[960]+[576]--------> 1536 cm²

This year, a small business had a total revenue of $40,700. If this is 26% less than their total revenue the previous year, what

Virty [35]

26% less than a value is best found by multiplying by (100 - 26)% = 74% = 0.74
So previous year x 0.74 = 40,700
Previous year = 40,700 / 0.74 = $55,000

HELP ME PLZZZ

Setler79 [48]

H = height of triangle
b = length of triangle base
A = area of triangle

Recall the formula for area of a triangle :

A = 1/2 bh

Plug in what was given in the problem :

h = b - 5
A = 42

A = 1/2 bh
42 = 1/2 b (b-5)

Question 6 2 pts

astraxan [27]

Answer:

785 acres

Step-by-step explanation:

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

Let X represent the random variable amount of corn yield

Assuming the X follows a normal distribution

$X \sim N(\mu, \sigma)$

And we know that the average $\bar X$ is dsitributed:

$\bar X \sim N(\mu=189.3, \sigma_{\bar X}=23.5)$

And we are interested on this probability:

$P(\bar X>180)$

For this case we can use the z score formula given by:

$z=\frac{\bar X -\mu}{\sigma_{\bar X}}$

If we apply this we got:

$P(\bar X>180)=P(Z>\frac{180-189.3}{23.5})=P(Z>-0.396)=1-P(Z$

And since we have a proportion estimated and we hava a total of 1200 acres the expected to yield more than 180 bushels of corn per acre would be:

$r=1200*0.654=784.8$

And if we round up this amount we got $\approx 785$ and that would be the best option for this case.

Each whole number from 0 to 9 is paired with its opposite. is this a function or not

dimaraw [331]

A function has the property that each element of the domain maps to only one element. For example, if there's ever the case where a relation includes point (1,2) and (1,3) then that relation is not a function. So for each case write down all the points as described. If one point in the domain ever maps to two different points, then it's not a function
