Use Pythagorean Theorem to find the diameter of the circle. Divide the diameter by 2 to find the radius, and solve for the area of the circle (πr^2). Then, solve for the area of the triangle (bh/2). Subtract the area of the triangle from the area of the circle.
Given: 5(x + 2) - 3 = 4(x - 1)
Prove: x = -11
Statement Reason
5(x + 2) - 3 = 4(x - 1) given
5x + 10 - 3 = 4x - 4 [?]
5x + 7 = 4x - 4 addition
5x = 4x - 11 subtraction
x = -11 subtraction
Answer:-11 proved
Step-by-step explanation:
5(x+2)-3=4(x-1)
Open brackets
5x+10-3=4x-4
Collect like terms
5x-4x=-4+3-10
x=-11

The altitude of an airplane is decreasing at a rate of 44 feet per second. What is the change in altitude of the airplane over a period of 34 seconds?
Answer:
1320 feet
Step-by-step explanation:
All we have to do is multiply the rate of change of altitude by the time it took the altitude to change.
The altitude of an airplane is decreasing at a rate of 44 feet per second. After 30 seconds, the change is altitude is:
44 * 30 = 1320 feet
The altitude of the airplane has changed by 1320 feet.

Simon knows that 25% of the people at a movie theater are seeing a romantic comedy. How many people are at the movie theater if 55 people are seeing a romantic comedy?
Answer:
220
Step-by-step explanation:
Number of people in theater = x
25% * x = 55
x = 55 / 25% = 55 / 25 * 100 = 55 * 4 = 220
13x=-21-6y and -8x=36+6y
Answer:
[tex]x=3\\y=-10[/tex]
Step-by-step explanation:
[tex]13x=-21-6y\\-8x=36+6y[/tex]
Let's take one of the equations and solve for x. I'll take the first one.
[tex]13x=-21-6y[/tex]
Divide by 13.
[tex]x=\frac{-21-6y}{13}[/tex]
Now replace x in the second equation.
[tex]-8x=36+6y\\-8(\frac{-21-6y}{13} )=36+6y[/tex]
Distribute -8
[tex]\frac{168+48y}{13}=36+6y[/tex]
Break down the fraction.
[tex]\frac{168}{13}+\frac{48}{13}y=36+6y[/tex]
Subtract [tex]\frac{168}{13}[/tex]
[tex]\frac{48}{13}y=36+6y-\frac{168}{13}[/tex]
Subtract 6y
[tex]\frac{48}{13}y-6y=36-\frac{168}{13}[/tex]
Combine like terms;
[tex]\frac{48-13*6}{13}y=\frac{36*13-168}{13}[/tex]
Solve;
[tex]\frac{48-78}{13}y=\frac{468-168}{13}[/tex]
Keep solving;
[tex]\frac{-30}{13}y=\frac{300}{13}[/tex]
Multiply by the negative reciprocal of the fraction next to y.
[tex](-\frac{13}{30} )\frac{-30}{13}y=\frac{300}{13}(-\frac{13}{30} )[/tex]
On the right side; 13 and 13 become 1. 300/30 = 30/3 = 10
[tex]y=-10[/tex]
After having found y, replace it in any of the equations to find x.
[tex]13x=-21-6y\\13x=-21-6(-10)\\13x=-21+60\\13x=39\\x=\frac{39}{13}\\ x=3[/tex]
Answer:
x=3
y=-10
Step-by-step explanation:
13x=-21-6y...............(1)
-8x=36+6y................(11)
Add (11) to (1)
5x=15-6y+6y
5x=15
Divide both sides by 5
5x/5=15/5
x=3
Substitute x=3 in 13x=-21-6y
13(3)=-21-6y
39=-21-6y
Collect like terms
39+21=-6y
60=-6y
Divide both sides by -6
60/-6=-6y/-6
-10=y
y=-10

Four people—Rob, Sonja, Jack, and Ang—enter their names into a drawing. The winner receives either a t-shirt or a mug, and which prize they receive is randomly selected.
What is the probability that either Ang wins and is given a mug, or Jack wins (and is given either prize)? Give the answer as a percent.
Answer:
3.125%Step-by-step explanation:
It is assumed the first winner is part of the second drawing as well
There are 4 people and two prizes
The probability of each person to win is 1/4
The first winner has 1/2 probability to get a mug
P(win and a mug) = 1/4*1/2 = 1/8 for AngThe second winner, if it is Jack, gets either prize
P(win and either prize) = 1/4The combined probability is:
1/8*1/4 = 1/32 = 0.03125 = 3.125%Answer:
The probability is 37.5%
Step-by-step explanation:
There are eight total outcomes, but we only need to focus on three. Ang winning a mug and Jack winning either a t-shirt or a mug, that makes three. Write that as a fraction: 3/8, and then divide. 3 divided by 8 gives us 0.375. But we need a percent so multiply that by 100, that now gives us 37.5.
So, the probability that either Ang wins and is given a mug, or Jack wins is 37.5%. If it makes you feel more confident in this, I put the same exact answer for my assessment and I got it correct.

determine the sample space of all of the possible outcomes of choosing a card numbered 1,2,3, or 4 and a blue, green, or yellow marble. how many outcomes involve choosing a blue marble
Answer:
a) Sample Space = {(1,blue), (1, green), (1, yellow), (2,blue), (2, green), (2, yellow), (3,blue), (3, green), (3, yellow), (4,blue), (4, green), (4, yellow)}
b) 4 outcomes involve choosing blue marble.
Step-by-step explanation:
a) FOR SAMPLE SPACE:
No. of options for choosing card = 4
No. of options for choosing marble = 3
No. of options for choosing a card and a marble = (3)(4) = 12
Therefore,
Sample Space = {(1,blue), (1, green), (1, yellow), (2,blue), (2, green), (2, yellow), (3,blue), (3, green), (3, yellow), (4,blue), (4, green), (4, yellow)}
b) CHOOSING BLUE MARBLE:
It is evident from the sample space that, there are only 4 outcomes, which involve choosing a blue marble.
Those 4 outcomes are as follows:
(1, blue), (2, blue), (3, blue), (4, blue)
Answer:
12

In his statistics class, Sam said, “Linear regression model is a tool to predict the relationship between the dependent variable, and independent variable. So, there will be one specific linear regression model that I can use to know the relationship of variables. I decided to use ordinary least square to have the best estimates for linear regression model parameters because ordinary lease square makes me find the linear regression equation with minimum average of difference between actual dependent variable and the value predicted by linear regression model.” Is Sam correct? If not, how do we need to fix his idea?
Answer:
Yes, Sam is correct and there is no need to fix his idea.
Step-by-step explanation:
Linear Regression model is one of the Important model that is been used in statistics especially in statistics which actively involved data analysis of dependent variable and an independent variable. Between these two that is dependent variable and an independent variable, the application of Linear Regression model is used in showing the relationships between the two variables.
Just like Sam said in the question above, '' “Linear regression model is a tool to predict the relationship between the dependent variable, and independent variable...'', that is what linear regression is used for.
Answer:
Yes, obviously Sam is correct
Step-by-step explanation:
Linear regression model is a tool to predict the relationship between the dependent variable, and independent variable
Linear Regression model is one of the Important model that is been used in statistics involved data analysis of dependent variable and an independent variable. Between these two that is dependent variable and an independent variable, the application of Linear Regression model is used in showing the relationships between the two variables.
help please quick 29 points please answer
Answer:
Step-by-step explanation:
It costs $7 for 1 baseball and Mrs.Weeks is buying 36 baseballs, that would be: $7 X 36 = $252
It costs $5 for 1 softball and Mrs.Weeks is buying 24 softballs that would be:
$5 X 24 = $120
$252 + $120 = $372 for the baseballs and softballs
Mrs.Weeks gives the cashier four $100 bills that is $400 dollars.
so $400 - $372 = $28 (Mrs.Weeks change)

Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
Firstly, [tex]x^{-y} = \frac{1}{x^y}[/tex], so in this case, you multiply [tex](6^{-8})^4[/tex], which equals [tex]6^{-32}[/tex]. Then, plug it into [tex]x^{-y} = \frac{1}{x^y}[/tex] and you get
[tex]6^{-32} = \frac{1}{6^{32}}[/tex], so it's [tex]\boxed{A.}[/tex]
