As you can see there are two triangles but it can be done calculating just for one. First we must understand how formula for area of triangle works.

A=\frac{1}{2}bh

Where b represents base (hypotenuse) and h as height of the triangle.

We know that:

b=13cm \\h=4cm

Using this data we fill the formula.

A=\frac{1}{2}\cdot13\cdot4=\frac{13\cdot4}{2}=13\cdot2=\boxed{26cm^2}

Hope this helps.

I REALLY NEED HELP ON 40 and 41, 50 POINTS
photoshop1234 [79]
Question 40 is D because from looking at the graph, its is symmetrical and the mean is the average, which usually the middle of the graph, so is the median. The median and mean would be within the 2.1-3 category because its the middle of the graph.

Question 41 is B because every pound is 16 ounces. If you multiply 16 and 12.5, you'll get 200.

Answer:

Step-by-step explanation:

Part 1

P(z < -1.45)

Using the z score table

P =

Part 2

We solve using z score formula

z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

a) P(X >52)

x = 52

Mean = 60

Standard deviation = 8

z = 52 - 60/8

z = -1

P-value from Z-Table:

P(x<52) = 0.15866

P(x>52) = 1 - P(x<52) = 0.84134

b) P(48 < x < 64)

Amber is starting a garden. She plants 2 flowers the first month. The next month, she plans three times more flowers (6 flowers)
Artist 52 [7]
This is a geometric progression problem. We can the general formula that can tell us how many flowers would be planted each month.
Let's write the terms that we know and see if we can find the pattern:
&#10;\begin{tabular}{lll}&#10;Month & Number of flowers planted & Different form            \\&#10;1     & 2                         & 2\cdot3^0 \\&#10;2     & 6                         & 2\cdot3^1 \\&#10;3     & 18                        & 2\cdot3^2 \\&#10;4     & 54                        & 2\cdot3^3&#10;\end{tabular}&#10;\end{table}
The patern here is obvious. Let's write it down:
N=2\cdot3^{n-1}
This formula gives us a number of flowers planted in the n-th month.
