Step-by-step explanation:
To solve for q, we apply the leg rule theorem or leg geometric mean theorem :
The hypotenus = 18 + 4 = 22
Leg 1 = b
Part1 = 4
According to the leg rule theorem :
Hypotenus / leg 1 = leg 1 / part 1
22 / b = b / 4
Cross multiply :
b * b = 22 * 4
b² = 88
b = √88 = √88 = √4 * √22 = 2√22
From Pythagoras :
a² = b² - 4²
a² = (√88)² - 16
a² = 88 - 16
a² = 72
a = √72 = √36 * √2 = 6√2

1. A resident lot has the shape of a parallelogram. Its base measures 20 meters. The distance between the
parallel sides is 8 meters. What is the area of the lot?
Answer:
160 m²
Step-by-step explanation:
Given :
A parallelogram shaped lot :
Base of lot = 20 m
Distance between parallel sides, = height of lot = 8 m
The area of the lot can be obtained using the area formula of a parallelogram :
Area = base * height
Area = 20 m * 8 m
Area = 160 m²

Suppose that a population parameter is 0.3, and many samples are taken from the population. As the size of each sample increases, the mean of the sample proportions would approach which of the following values? O A. 0.4 O B. 0.1 O C. 0.3 O D. 0.2 SUBMIT
Using the Central Limit Theorem, it is found that the mean of the sample proportions would approach 0.3, hence option C is correct.
What does the Central Limit Theorem states?It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex], as long as [tex]np \geq 10[/tex] and [tex]n(1 - p) \geq 10[/tex].

How can you use problem-solving strategies in solving personal, professional, and mathematical problems? Explain in 5-7 sentences and I will mark you the brainliest.
Answer:
Step-by-step explanation:
Problem-solving strategies are created as ways of making a problem easier to understand and this leads to it being easier to solve. For example, one strategy is known as compartmentalizing. This involves splitting a problem into various smaller problems. It makes solving these smaller problems easier and less stressful, and once the smaller problems are solved the bigger one is automatically solved as well. Such a strategy can be applied to any problem in any category including math.

To test this series for convergence
∝
∑ (4^n+7)/7^n
n=1
You could use the limit comparison test, comparing it to the series
∝
∑ r^n
n=1
Where r=???
Completing the test, it shows the series:
r should be 4/7. You're comparing the given series to a geometric series that converges. By the limit comparison test, you have
[tex]\displaystyle\lim_{n\to\infty}\frac{\frac{4^n+7}{7^n}}{\frac{4^n}{7^n}}=\lim_{n\to\infty}\frac{4^n+7}{4^n}=\lim_{n\to\infty}\left(1+\frac7{4^n}\right)=1[/tex]
and since this limit is positive and finite, and the series you're comparing to is convergent, then the first series must also be convergent.

FIND ALL THREE ANGLES
Answer:
Austin = 38
Atlanta = 89
Chicago = 89
Step-by-step explanation:
First, solve for x. All angles together equal 180. Set your formula up as
180 = 2x - 12 + 2x + 3 + 4x - 11
180 = 8x -20
180 + 20 = 8x
200 = 8x
200 / 8 = x
25 = x
Now substitute 25 in place of x
Austin
2x - 12
2*25-12 = 38
Atlanta
4x-11
4*25-11 = 89
Chicago
2x+3
2*25+3 = 53
Add all your angles together to check your work

=========================================================
Explanation:
The horizontal pieces are the parallel bases
b1 = 17 and b2 = 9
The height is always perpendicular to the base, so h = 8
The 4 ft portion won't be used in the next section, so we can ignore it.
---------
Plug the values mentioned into the trapezoid area formula below. Simplify.
A = h*(b1+b2)/2
A = 8*(17+9)/2
A = 8*26/2
A = 8*13
A = 104 square feet
We can abbreviate "square feet" into "sq ft" or "ft^2" without quotes.
----------
As another approach, you can split the trapezoid into 2 triangles and a rectangle in between. Then find the area of each small piece, and add up those smaller areas to get the final answer. You should get 104. If you go with this approach, then you will use the 4 ft portion to help find the horizontal length of the triangle on the right.

O Jada should use the tank of tennis balls.
O Jada should use the tank of golf balls.
1b. Explain your reasoning."
Answer:
Step-by-step explanation:
What Jada needs is a tank which gives him a higher or greater probability of selecting an even number :
Tennis balls :
Total outcome = 10
Even outcomes = (2, 4) = 2
Golf balls :
Total outcome = 10
Even outcomes = (4,2,6,2,2,4,8) = 7
Probability = number of outcomes / number of trials
For tennis balls
P(even) = 2 / 10 = 0.5
For golf :
P(even) = 7/10 = 0.
