This one takes time to type all the math work.
Let me see.
There are two triangles here.
They both have the same area.
A = (1/2)(base)(height) times 2
A = (1/2)(42)(56) times 2
A = 1,176 times 2
A = 2,352 inches^2.
We also have three rectangles. We need to find the area of each rectangle individually.
Area of bottom rectangle = 42 times 72 or 3,024 inches^2.
Area of back rectangle = 56 times 72 or 4,032 inches^2.
Area of slanted rectangle = 70 times 72 0r 5,040 inches^2.
We now add all the areas together to find the total area of the entire figure.
Total Area = 2,352 inches^2 + 3,040 inches^2 + 4,032 inches^2 + 5,040 inches^2
Total area = 14,448 inches^2
Done!

(5 points) The population of a state changes due to births, deaths, and immigration. The annual birth rate is 14.3 births per 1000 residents, the death rate is 11.8 deaths per 1000 residents, the immigration rate into the state is 21.6 immigrations per 1000 residents, and the emigration rate out of the state is 5.5 emigrations per 1000 residents. Find the population growth rate as a percentage.
Answer:
The population growth rate is of 1.86%.
Step-by-step explanation:
Population growth rate:
Immigration plus births subtracted by emigration and deaths.
In this question, we have that:
Birth: 14.3 per 1000
Death: 11.8 per 1000
Immigrations: 21.6 per 1000
Emigrations: 5.5 per 1000
Rate:
[tex]\frac{14.3 + 21.6 - 11.8 - 5.5}{1000} = \frac{18.6}{1000} = 0.0186[/tex]
As a percentage:
Multiply by 100%. So
0.0186*100% = 1.86%
The population growth rate is of 1.86%.

[tex] \frac{x - 3 }{x + 2} + \frac{3x - 3}{(x + 1)(x + 2} = \frac{x}{x + 1} - \frac{x - 2}{x + 2} [/tex]
Given:
The equation is:
[tex]\dfrac{x-3}{x+2}+\dfrac{3x-3}{(x+1)(x+2)}=\dfrac{x}{x+1}-\dfrac{x-2}{x+2}[/tex]
To find:
The solution for the given equation.
Solution:
We have,
[tex]\dfrac{x-3}{x+2}+\dfrac{3x-3}{(x+1)(x+2)}=\dfrac{x}{x+1}-\dfrac{x-2}{x+2}[/tex]
Taking LCM on both sides, we get
[tex]\dfrac{(x-3)(x+1)+3x-3}{(x+1)(x+2)}=\dfrac{x(x+2)-(x+1)(x-2)}{(x+1)(x+2)}[/tex]
[tex](x-3)(x+1)+3x-3=x(x+2)-(x+1)(x-2)[/tex]
[tex]x^2+x-3x-3+3x-3=x^2+2x-(x^2-2x+x-2)[/tex]
[tex]x^2+x-6=x^2+2x-x^2+2x-x+2[/tex]
On further simplification, we get
[tex]x^2+x-6=3x+2[/tex]
[tex]x^2+x-6-3x-2=0[/tex]
[tex]x^2-2x-8=0[/tex]
Splitting the middle term, we get
[tex]x^2-4x+2x-8=0[/tex]
[tex]x(x-4)+2(x-4)=0[/tex]
[tex](x+2)(x-4)=0[/tex]
[tex]x=-2,4[/tex]
But [tex]x\neq -2[/tex] because for [tex]x=-2[/tex] the given equation is not defined.
Therefore, the only solution of the given equation is [tex]x=4[/tex].
A shipment of fibers is not acceptable if the mean breaking strength of the fibers is less than 50.03 N. A large sample of fibers from this shipment was tested, and a 98% lower confidence bound for the mean breaking strength was computed to be 50.1 N. Someone suggests using these data to test the hypotheses H0 : μ ≤ 50.03 versus H1 : μ > 50.03. Is it possible to determine from the confidence bound whether P < 0.01? Explain.
Answer:
NO it is not possible
Step-by-step explanation:
It is not possible to determine from the confidence bound whether p < 0.01 and this is because since the 50.03 is less than 98% lower confidence bound which is 50.1 N , we know that p value < 0.03 but P value might be ≥ 0.01 . hence we cannot determine from the confidence bound whether p < 0.01

Answer:
Shaded area is 392
Step-by-step explanation:
The triangles on the left have heights 14 and 14, the ones on the right have 20 and 8.
The bases are equal, so we can compute them as (40-12)/2 = 28/2 = 14
The triangles have areas:
14*14/2 = 14*7 = 98
14*14/2 = 14*7 = 98
20*14/2 = 20*7 = 140
8*14/2 = 8*7 = 56
note that the triangles on the left and the ones on the right have the same total area! That would have happened no matter what the height split was!
The total area is 98+98+140+56 = 196 + 196 = 392

Toni runs a restaurant that receives a shipment of 200 oranges every day. According to the supplier,
approximately 11% of the population of these oranges is overripe. Suppose that Toni calculates the daily
proportion of overripe oranges in her sample of 200. We can assume the supplier's claim is true, and that the
oranges each day represent a random sample.
What will be the shape of the sampling distribution of the daily proportions of overripe oranges?

Answer:
Step-by-step explanation:
You are trying to find the value of K, so to do that you need to get k by itself (example : K= 3-5 instead of K+5= 3)
So in 1a i would simplify 7k-3k= 4k
then 4k=11
now to get rid of the 4 and get the k alone- you DIVIDE 4k by 4 and divide 11 by 4 cause you need to do it on both sides of the equation, it should look like this.
4k= 11
- = -
4 4
(4k over 4 and 11 over four)
so the answer is k = 2.75 cause 11/4 = 2.75
Nolan has a points card for a movie theater.

Answer:
V>_8
Step-by-step explanation:
20+2.5v >_ 40
The number of visits Nolan can make to earn his first free movie ticket is 8.
How many visits before Nolan wins a free movie ticket?The inequality that represents the information in the question is: 20 + 2.5x ≥ 40.
Where x represents the number of visits to the movie theater.
In order to determine the value of x, take the following steps combine similar terms
2.5x ≥40 - 20
Add similar terms
2.5x ≥ 20
Divide both sides by 2.5
x ≥ 8

Liquid products were first obtained from coal in England during the 1700s. Lamp oil was produced from coal in the United States as early as 1850, but the domestic coal chemicals industry did not develop until World War I. A modern coal - for - recovery system uses a battery of coke ovens to produce liquid products from coal feed. These observations are obtained on the random variable X, the number of gallons of liquid product obtained per coal feed: (insert data)

What area is this shape ?
9514 1404 393
Answer:
40 square units
Step-by-step explanation:
The area can be considered as that of two trapezoids, a rectangle, and a triangle. The total area is the sum of the areas of these.
Draw two horizontal lines, one beginning at the left-most point, and another 2 units below that. Draw a vertical line segment extending the vertical line at the top down to the first horizontal line. Now the figure is divided as described above.
The upper left trapezoid has bases of 3 and 5, and a height of 4. Its area is ...
A = 1/2(b1 +b2)h
A = (1/2)(3 +5)(4) = 16
The trapezoid between the two horizontal lines has bases of 8 and 7, and a height of 2. Its area is ...
A = (1/2)(8 +7)(2) = 15
The rectangle at upper right has a base of 2 and a height of 3. Its area is ...
A = bh
A = 2(3) = 6
The triangle at the bottom has a base of 3 and a height of 2. Its area is ...
A = 1/2bh
A = 1/2(3)(2) = 3
Then the total area of all of these pieces is ...
Area = 16 +15 +6 +3 = 40 . . . . square units
Answer:
the answer is 40 square units
Of the 50 plays attributed to a playwright, 18 are comedies, 13 are tragedies, and 19 are histories. If one play is selected at random, find the odds against selecting a tragedy or a comedy.
Answer:
Given:
50 plays
31/50 are comedies or tragedies
19/50 are histories.
If one is selected at random,
the chances decrease dramatically,
so :
19/50 * 19/50 = 361/2500 = .1444
Less than .2 percent.

Find the indicated area under the standard normal curve.
The total area to the left of z= - 1.18 and to the right of z= 1.18 under the standard normal curve is ___.
Answer:
0.1190
Step-by-step explanation:
If z = -1.18, the total area to the left under the standard normal curve is taken from the z-distribution table attached;
P(z < - 1.18) = 0.1190
Also, to the right of z = 1.18, we have;
P(z > 1.18) = 1 - P(z < 1.18)
From the second image attached from z-table, we have;
P(z > 1.18) = 1 - 0.8810
P(z > 1.18) = 0.1190
Thus, the total area to the left of z= - 1.18 and to the right of z= 1.18 under the standard normal curve is 0.1190

30) The sum of three consecutive numbers is 27. What are the three numbers? A. 8, 9, 10 B. 6, 7 8 C. 11, 12, 13 D. 9, 10, 11
Answer:
The answer is A. 8, 9, 10
Answer:
A. 8, 9, 10.
Step-by-step explanation:
Consecutive numbers counting numbers which are 1 greater than the other, therefore:
x + (x + 1) + (x + 2) = 27
(x + x + x) + (1 + 2) = 27
3x + 3 = 27
–3 –3
3x = 24
÷3 ÷3
x = 8.
x = 8 → [ x + (x + 1) + (x + 2) ] =
(8) + (8 + 1) + (8 + 2) = 8 + 9 + 10

Answer:
5 1/2
Step-by-step explanation:
You can use the distributive property to eliminate parentheses, then add the terms that result.
5(3/5 +1/2) = 5(3/5) +5(1/2) = 3 + 5/2 = 3 + 2 1/2 = 5 1/2
__
Or, you can add the numbers, then multiply by 5. This is the way the evaluation should be done according to the Order of Operations.
5(3/5 +1/2) = 5(6/10 + 5/10) = 5(11/10) = 11/2 = 5 1/2
Answer:
5 1/2.
Step-by-step explanation:
5*(3/5+1/2)
= 5 * (6/10 + 5/10)
= 5 * 11/10
= 55/10
= 5 1/2.
