Answer:
5. 37.065 square centimeters
6. 241 square centimeters
Step-by-step explanation:
5. First, separate the figure into shapes you can find the areas of. This first figure can be represented by two rectangles and one quarter circle.
The two rectangles can be found using a = bh, or 5x3! Both of the rectangles' areas are equal to 30cm.
The circle's area can be found using a = pi(r^2). r stands for radius, which can be represented by 3cm. The area of a whole circle with a radius of 3 is 28.26 cm. Because it is a quarter circle, however, we can divide this value by four to get an area of 7.065cm.
If you add them all together, you get an area of 37.065.
6. First, separate the figure into shapes you recognize. This one can be separated into one triangle and one rhombus.
You can find the area of the triangle using the formula: a = 1/2bh. This gets you an area of 88cm.
The rhombus can be found using the formula: a = 1/2(b1+b2)h. Essentially, you find the average of the two bases and multiply it by the height! This gets you an area of 153cm.
Now, simply add the two areas together and you get an area of 241cm!

A variable is a quantity that can change; the word also refers to the letter or symbol that represents this quantity. In a proportional relationship, one variable is the independent variable, and one is the dependent variable. They are often called "x" and "y," but any letters can be used. The value of the dependent variable depends on the value of the independent variable. In the relationship between number of scoops of ice cream and total price, we can call number of scoops "x" and total price "y." Y is dependent because its value depends on x, the number of scoops you purchase. Ursula makes $5 for every 1 dog she walks.

In one year, the Perseid meteor shower had a meteor appear every 1 1/5 minutes on average. That same year, the Leonid meteor shower had a meteor appear every 4 2/3 minutes on average. How many more meteors fell during the Perseid meteor shower?
Answers
Answer:
325,452 more meteors fell during the Perseid meteor shower
Step-by-step explanation:
An year has 365 days.
Each day has 24 hours.
Each hour has 60 minutes.
Minutes in an year:
365*24*60 = 525600
Persoid:
[tex]1 + \frac{1}{5} = 1 + 0.2 = 1.2[/tex]
One each 1.2 minutes. How many during an year?
1 meteor - 1.2 minutes.
x meteors - 525600 minutes.
[tex]1.2x = 525600[/tex]
[tex]x = \frac{525600}{1.2}[/tex]
[tex]x = 438000[/tex]
438,000 meteors fell during the Persoid shower.
Leonid:
[tex]4 + \frac{2}{3} = 4.67[/tex]
One each 4.67 minutes. How many during an year.
1 meteor - 4.67 minutes.
x meteors - 525600 minutes.
[tex]4.67x = 525600[/tex]
[tex]x = \frac{525600}{4.67}[/tex]
[tex]x = 112548[/tex]
112,548 meteors fell during the Leonid Shower.
How many more meteors fell during the Perseid meteor shower?
438,000 - 112,548 = 325,452
325,452 more meteors fell during the Perseid meteor shower
Triangle L J K is shown. Angle J L K is a right angle. The length of the hypotenuse is 15 inches and the length of the side adjacent to the right angle is 10 inches. The angle between the 2 sides is x.
Which equation can be used to find the measure of angle LJK?
Answers
Answer:
The answer is C on Edge 2020
Step-by-step explanation:
The value of x will be 48.19°. Then the measure of angle LJK will be 41.81°.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
Triangle LJK is shown.
Angle ∠JLK is a right angle.
The length of the hypotenuse is 15 inches, and the length of the side adjacent to the right angle is 10 inches.
The angle between the 2 sides is x.
Then the measure of the angle x will be given by cosine of x.
cos x = 10 / 15
cos x = 0.667
x = 48.19°
The value of x will be 48.19°.
We know that the sum of the angle of triangle is 180°.
Then the measure of angle LJK will be
∠LJK + 90° + 48.19° = 180°
∠LJK = 41.81°

According to a recent survey, the mean income before taxes of consumer units (i.e., households) in the U.S. was $60,533 with a margin of error equal to 1406.32 (for a 95% confidence level). Calculate a 95% confidence level for the population mean income before taxes for all U.S. consumer units.A (58,681.82, 62,384.18)B (57,776.61, 63,289.39)C (59,097.98, 61,968.02)D (59,126.68, 61,939.32)E (60,166.92, 60,899.08)
Answers
Answer:
D (59,126.68, 61,939.32)
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound. These bounds depend of the sample mean and of the margin of error.
The lower bound is the sample mean subtracted by the margin of error.
The upper bound is the margin of error added to the sample mean.
In this question:
Sample mean: 60,533
Margin of error: 1406.32
Lower bound: 60,533 - 1406.32 = 59,126.28
Upper bound: 60,533 + 1406.32 = 61,939.32
So the correct answer is:
D (59,126.68, 61,939.32)

83 random samples were selected from a normally distributed population and were found to have a mean of 32.1 and a standard deviation of 2.4. Construct a 90% confidence interval for the population standard deviation.
Answers
Answer:
[tex]\frac{(82)(2.4)^2}{104.139} \leq \sigma^2 \leq \frac{(82)(2.4)^2}{62.132}[/tex]
[tex] 4.525 \leq \sigma^2 \leq 7.602[/tex]
Now we just take square root on both sides of the interval and we got:
[tex] 2.127 \leq \sigma \leq 2.757[/tex]
Step-by-step explanation:
Information given
[tex]\bar X=32.1[/tex] represent the sample mean
[tex]\mu[/tex] population mean (variable of interest)
s=2.4 represent the sample standard deviation
n=83 represent the sample size
Confidence interval
The confidence interval for the population variance is given by the following formula:
[tex]\frac{(n-1)s^2}{\chi^2_{\alpha/2}} \leq \sigma^2 \leq \frac{(n-1)s^2}{\chi^2_{1-\alpha/2}}[/tex]
The degrees of freedom given by:
[tex]df=n-1=8-1=7[/tex]
The confidence level is 0.90 or 90%, the value of [tex]\alpha=0.1[/tex] and [tex]\alpha/2 =0.05[/tex], and we can use excel, a calculator or a table to find the critical values.
The excel commands would be: "=CHISQ.INV(0.05,82)" "=CHISQ.INV(0.95,82)". so for this case the critical values are:
[tex]\chi^2_{\alpha/2}=104.139[/tex]
[tex]\chi^2_{1- \alpha/2}=62.132[/tex]
The confidence interval is given by:
[tex]\frac{(82)(2.4)^2}{104.139} \leq \sigma^2 \leq \frac{(82)(2.4)^2}{62.132}[/tex]
[tex] 4.525 \leq \sigma^2 \leq 7.602[/tex]
Now we just take square root on both sides of the interval and we got:
