Answer:
B) f(x) = -3/5x +5
Step-by-step explanation:
There are several ways you can write the equation of a line from a list of points. When you look through the list and see that one of them is the y-intercept, then the problem can be easier. When you look through the list of answers and see that the required answer is in slope-intercept form, then you know all you need to do is find the slope to go with the intercept you've located. The point (x, f(x)) = (0, 5) tells you the y-intercept is 5.The slope, the change in y divided by the change in x for two points, is ...... (-1 -2)/(10 -5) = -3/5This is the slope and the coefficient of x in the linear equation.Now, we know the y-intercept (b=5) and the slope (m=-3/5), so we can fill in the slope-intercept form of the equation of a line:... y = mx + b... y = (-3/5)x + 5

4. Wanda lives in the same state as Reese (ex 4 p 313). Her weekly unemployment
compensation is $360. What were the total 26-week earnings for her highest two consecutive
quarters of employment?
Final answer:
To find the total earnings for Wanda's highest two consecutive quarters of employment, multiply her weekly unemployment compensation by the number of weeks in two quarters.
Explanation:
To find the total earnings for Wanda's highest two consecutive quarters of employment, we need to compare the given state and weekly unemployment compensation with the table provided. According to the table, the maximum weekly unemployment compensation for Oregon is $330. Since Wanda's weekly compensation is $360, it means that her state is Oregon. Now, we can find the total earnings for her highest two consecutive quarters by multiplying her weekly compensation by the number of weeks in two quarters (26 weeks).
$360 times 26 (*) = $9360
Therefore, the total 26-week earnings for Wanda's highest two consecutive quarters of employment is $9360.

-16-10.2g = -14.7g + 16.85
a. 147.825
b. -7.3
c. 3.65
d. 7.3
Please select the best answer from the choices provided
Answer:
d. 7.3
Step-by-step explanation:
-16-10.2g = -14.7g + 16.85
4.5g = 32.85
g = 7.3
The solution for the equation -16 - 10.2g = -14.7g + 16.85 is g = 7.3. You can verify it by substituting the solution back into the original equation.
Explanation:To solve the given equation, -16 - 10.2g = -14.7g + 16.85, we must first isolate the variable, g, by moving all terms involving g to one side of the equation and constant terms to the other side. Add 10.2g to both sides of the equation, giving, -16 = -4.5g + 16.85. To further isolate g, subtract 16.85 from both sides resulting in -32.85 = -4.5g. Finally, divide by -4.5 to solve for g. Thus, g = -32.85 / -4.5 = 7.3. We verify our solution by substituting 7.3 back into the original equation and confirming that the equality holds true.

Answer:
45.8
Step-by-step explanation:
We can use the Pythagorean theorem with legs 3x and 4x+7
a^2+ b^2 = c^2
(3x^2) +(4x+7)^2 = c^2
Let x = 8
(3*8)^2 + (4*8+7)^2 = c^2
24^2+ 39^2 = c^2
576+1521 = c^2
2097 = c^2
Take the square root of each side
sqrt(2097) = sqrt(c^2)
45.79301257 =c
Rounding to the nearest tenth
45.8 =c
Answer:
45.8
Step-by-step explanation:
First solve for the other two sides by replacing x with 8
4(8)+7 = 39
3(8) = 24
Then use the pythagorean theorem ([tex]a^{2} + b^{2} = c^{2}[/tex]) to solve for the hypotenuse, c being the hypotenuse
[tex]39^{2} + 24^{2} = c^{2}[/tex]
1521 + 576 = [tex]c^{2}[/tex]
2097 = [tex]c^{2}[/tex]

Manuela and Stephen survey 250 people at a sporting event and ask if they prefer hamburgers or hot dogs, and if they prefer regular or diet soda.
Regular Soda Diet Soda Total
Hamburgers 90 40 130
Hot Dogs 70 50 120
Total 160 90 250
a. What is the probability that someone who prefers diet soda will also prefer hamburgers?
b. What is the probability that someone who prefers hot dogs will also prefer regular soda?
c. Are preferring diet soda and preferring hamburgers independent events? Explain.
d. Are preferring regular soda and preferring hot dogs independent events? Explain.
Answer:
a. 40/250
b. 70/250
c. Preferring diet soda and preferring hamburgers are not independent events
d. Preferring regular soda and preferring hot dogs are not independent events
Step-by-step explanation:
We are given:
Regular Soda Diet Soda Total
Hamburgers 90 40 130
Hot Dogs 70 50 120
Total 160 90 250
a. The probability that someone who prefers diet soda will also prefer hamburgers can be calculated as:
No. of people who prefer hamburgers and diet soda / Total no. of people
40/250
b. The probability that someone who prefers hot dogs will also prefer regular soda can be calculated as:
No. of people who prefer hot dogs and regular soda/Total no. of people
70/250
c. For two events to be independent, they must fulfill the condition:
P(A and B) = P(A) * P(B)
P(Diet Soda) = No. of people who prefer diet soda/total no. of people
= 90/250
P(Hamburgers) = No. of people who prefer hamburgers/total no. of people
= 130/250
P(Diet Soda and Hamburgers) = 40/250
Now, we need to check:
P(Diet Soda and Hamburgers) = P(Diet Soda) * P(Hamburgers)
40/250 = 90/250 * 130/250
40/250 ≠ 11700/62500
So, we can conclude that these two events are not independent events.
d. P(Regular Soda) = No. of people who prefer regular soda/total no. of people
= 160/250
P(Hot dogs) = No. of people who prefer hot dogs/total no. of people
= 120/250
P(Regular Soda and Hot Dogs) = 70/250
Now, we need to check if:
P(Regular Soda and Hot Dogs) = P(Regular Soda) * P(Hot dogs)
70/250 ≠ 160/250 * 120/250
So, these two events are not independent.
The solutions obtained are Part (a): The probability is 0.444, Part (b): The probability is 0.583, Part (c): Preferring diet soda and preferring hamburgers are not independent and Part (d): Preferring regular soda and preferring hot dogs are not independent.
Probability and Independence Analysis
Let's analyze the data provided from Manuela and Stephen's survey:
Regular Soda Diet Soda Total
Hamburgers 90 40 130
Hot Dogs 70 50 120
Total 160 90 250
→ Part A: Probability that Someone Who Prefers Diet Soda Also Prefers Hamburgers
The number of people who prefer diet soda is 90, and among them, 40 prefer hamburgers. Therefore, the probability is calculated as follows:
P(Hamburgers|Diet Soda) = 40 / 90
≈ 0.444
→ Part B: Probability that Someone Who Prefers Hot Dogs Also Prefers Regular Soda
The number of people who prefer hot dogs is 120, and among them, 70 prefer regular soda. Therefore, the probability is:
P(Regular Soda|Hot Dogs) = 70 / 120
≈ 0.583
→ Part C: Independence of Preferring Diet Soda and Preferring Hamburgers
To determine if these events are independent, we check if:
P(Diet Soda AND Hamburgers) = P(Diet Soda) * P(Hamburgers)
Calculations:
→ P(Diet Soda AND Hamburgers) = 40 / 250
→ P(Diet Soda) = 90 / 250
→ P(Hamburgers) = 130 / 250
→ P(Diet Soda AND Hamburgers) ≠ P(Diet Soda) * P(Hamburgers)
Since the equality does not hold, these events are not independent.
Part D: Independence of Preferring Regular Soda and Preferring Hot Dogs
We test the same independence condition for regular soda and hot dogs:
→ P(Regular Soda AND Hot Dogs) = P(Regular Soda) * P(Hot Dogs)
Calculations:
→ P(Regular Soda AND Hot Dogs) = 70 / 250
→ P(Regular Soda) = 160 / 250
→ P(Hot Dogs) = 120 / 250
→ P(Regular Soda AND Hot Dogs) ≠ P(Regular Soda) * P(Hot Dogs)
Therefore, these events are also not independent.

Total including this is 40 points. + Brainliest.
Others unanswered 100 points in 3 questions.
Answer:
see below
Step-by-step explanation:
We need to find the diameter of the square
We can find this using the Pythagorean theorem
a^2+b^2 = c^2 where the legs are 7 and 7 and the diameter is c
7^2 +7^2 = c^2
49+49 = c^2
98 = c^2
Taking the square root of each side
sqrt(98) = sqrt(c^2)
9.899494937 = c
Since 9.9 is less than 11 which is the diameter of the circle it will never touch the circle.
Since the longest part of the square is less than the diameter of the circle, the square will fit inside the circle without touching
Answer:
Diagonal < Diameter
Step-by-step explanation:
The square will fit inside without touching if the diagonal length is less than the diameter
Diagonal = sqrt(7² + 7²)
7sqrt(2)
Diameter = 11
7sqrt(2) < 11
Because
(7sqrt(2))² < 11²
98 < 121

If x = time, and y = the number of problems in the set, which equation models the relationship?
Question 3 options:
y = 12x
y = x + 12
y = 1.2x
y = x + 1.2
Answer:
C, y = 1.2x
Step-by-step explanation:
Notice that x, representing time, is multiplied by 1.2 each time to get y, representing the number of problems. You can find this out by dividing y by x. 36/30 = 1.2.
48/40 = 1.2.
And so on...
P.S.: If you ever come across a problem like this, subtract one y value by another y value, then subtract the corresponding x values from eachother, then make both numbers into one fraction with y as the numerator and x as the denominator. In this problem, that would look like this:
48 and 36 are both y values: 48 - 36 = 12
40 and 30 are the corresponding x values: 40 - 30 = 10
We get 12/10, which can be simplified to 1.2. The slope is 1.2.
This method will always work for a straight line and will be taught to you soon if you haven't learned it already.
