Complete Question
In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 25% of your total grade, each major test is worth 22:5%, and the final exam is worth 30%. Compute the weighted average for the following scores: 92 on the lab, 81 on the first major test, 93 on the second major test, and 85 on the final exam. (Enter your answer to one decimal place)
Answer:
The weighted average is [tex]W = 87.65 [/tex]
Step-by-step explanation:
From the question we are told that
The worth of the lab score is 25% of total grade
The worth of each major test is 22.5% of total grade
The worth of final exam is 30% of total grade
The score on lab is 92
The score on first major test 81
The score on second major test 93
The score on final exam is 85
Generally the weighted score is mathematically represented as
[tex]W = 0.25 * 92 + 0.225* 81 + 0.225* 93 +0.30 * 85[/tex]
=> [tex]W = 0.25 * 92 + 0.225* 81 + 0.225* 93 +0.30 * 85[/tex]
=> [tex]W = 87.65 [/tex]
A=1/2(b1+b2) solve for b1
Answers
Given expression:
A = [tex]\frac{1}{2}(b_{1} + b_{2} )[/tex]
Solve for b₁;
Solution:
This is a subject of the formula problem.
Given expression:
A = [tex]\frac{1}{2}(b_{1} + b_{2} )[/tex]
First, multiply both sides by 2;
2 x A = 2 x [tex]\frac{1}{2}(b_{1} + b_{2} )[/tex]
2A = b₁ + b₂
Then subtract b₂ from both sides;
2A - b₂ = b₁ + b₂ - b₂
b₁ = 2A - b₂
The solution is b₁ = 2A - b₂

Answers
Let's see what to do buddy....
_________________________________
Remember from now on ,
rang = output
and also Remember ,
output = y = f(x)
So : range = f(x)
So we must put the range number instead of f(x) and solve for x.
Let's do it...
=======================================
[tex]f(x) = 1[/tex]
[tex] - 4x + 9 = 1[/tex]
Both sides minus 9
[tex] - 4x = 1 - 9[/tex]
[tex] - 4x = - 8[/tex]
Negatives simplified
[tex]4x = 8[/tex]
Divided both sides by 4
[tex]x = \frac{8}{4} \\ [/tex]
[tex]x = 2[/tex]
_________________________________
[tex]f(x) = - 3[/tex]
[tex] - 4x + 9 = - 3[/tex]
[tex] - 4x = - 3 - 9[/tex]
[tex] - 4x = - 12[/tex]
[tex]4x = 12[/tex]
[tex]x = \frac{12}{4} \\ [/tex]
[tex]x = 3[/tex]
_________________________________
[tex]f(x) = - 7[/tex]
[tex] - 4x + 9 = - 7[/tex]
[tex] - 4x = - 7 - 9[/tex]
[tex] - 4x = - 16[/tex]
[tex]4x = 16[/tex]
[tex]x = \frac{16}{4} \\ [/tex]
[tex]x = 4[/tex]
_________________________________
[tex]f(x) = - 15[/tex]
[tex] - 4x + 9 = - 15[/tex]
[tex] - 4x = - 15 - 9[/tex]
[tex] - 4x = - 24[/tex]
[tex]4x = 24[/tex]
[tex]x = \frac{24}{4} \\ [/tex]
[tex]x = 6[/tex]
_________________________________
[tex]f(x) = - 19[/tex]
[tex] - 4x + 9 = - 19[/tex]
[tex] - 4x = - 19 - 9[/tex]
[tex] - 4x = - 28[/tex]
[tex]4x = 28[/tex]
[tex]x = \frac{28}{4} \\ [/tex]
[tex]x = 7[/tex]
_________________________________
[tex]f(x) = - 23[/tex]
[tex] - 4x + 9 = - 23[/tex]
[tex] - 4x = - 23 - 9[/tex]
[tex] - 4x = - 32[/tex]
[tex]4x = 32[/tex]
[tex]x = \frac{32}{4} \\ [/tex]
[tex]x = 8[/tex]
=======================================
So the domain values are :
x = { 2 , 3 , 4 , 6 , 7 , 8 }

Rebecca’s boss pays her time and a half for overtime work. If her regular wage is $13.50 per hour, what is her overtime rate?
Answers
Answer:
Rebecca's overtime rate is $20.25 per hour
Step-by-step explanation:
Rebecca is paid $13.50 per hour as her regular wage.
Her boss pays her that amount and a half for overtime work.
Half of her regular pay rate is 13.50/2= $6.75
Thus, her overtime rate is:
$13.50 + $6.75 = $20.25
Rebecca's overtime rate is $20.25 per hour

the area of rectangle is 40 sq. cm. Find its length when it is 3 more than its width
Answers
Answer:
8 cm.
Step-by-step explanation:
Area = length × width
Use the variable w instead of width.
Area = w × (w+3)
Substitute 40 for the Area
40 = w × (w + 3)
Create a table to find the greatest common factors of 40.
1 × 40, not it because 40 is 39 units greater than 1, not 3
2 ×20, not it because 20 is 18 units greater than 2, not 3
4 × 10, not it because 10 is 6 units greater than 4, not 3
5 × 8, correct because 8 is 3 units greater than 5
Now substitute 5 for w to check your answer
40 = 5 × (5 +3 )
40 = 5 × 8
40 = 40
The answer is correct.

A rectangle is a quadrilateral with 4 sides. In a rectangle, one side is longer than the other. The longer side is called the width and the shorter side is called the length.
The length of the rectangle is 8cm.
The formula for the area of a rectangle is given as :
Length x Width
From the question, the length is 3 more than its width. We can represent this mathematically as:
L = W + 3
Area of the rectangle = 40 sq. cm
Inputting this into the formula
(W + 3) x W = 40
W² + 3W = 40
W² + 3W - 40 = 0
Factorise
W² +8W - 5W - 40 = 0
W(W + 8) - 5(W + 8) = 0
(W + 8)(W - 5) = 0
To find W
W + 8 = 0
W = - 8 or
W - 5 = 0
W = 5 cm
Therefore, the width is 5cm.
To find the length, L = W + 3
L = 5 + 3
L = 8 cm
Therefore, the length is 8 cm.

Step-by-step explanation:
In the game of Pick-A-Ball, there are 10 colored balls: 2 red, 4 white, and 4 blue. The balls have been placed into a small bucket, and the bucket has been shaken thoroughly. You will be asked to reach into the bucket without looking and select 2 balls. Because the bucket has been shaken thoroughly, you can assume that each individual ball is selected at random with equal likelihood of being chosen. It is common in games of chance to be rewarded for obtaining unlikely results. For example, in the game of poker, hands that are less likely to occur tend to trump hands that are more likely to occur. That same concept applies in this game. It costs $10 to play Pick-A-Ball, and your prize is the reciprocal of the probability of obtaining your exact sequence of results, expressed in dollars. For example, if the probability of obtaining your exact sequence of results is 0.10, your prize is 1/0.10 and you break even. Therefore, to make a positive profit from playing Pick-A-Ball, the probability of obtaining your results must be ower than 0.10. When you reach into the bucket, your result is based on a simulation. In a simulation, random events are modeled in such a way that the simulated outcomes closely match real-world outcomes. In this simulation, your result is simulated based on the robabiliies of obtaining a ball of a particular color. Now, close your eyes! Reach into the bucket, and pick a ball.

Hello,
This question you posted is incomplete but I was able to get the complete question. I hope it would be of help to you!
1. What is the probability of selecting the color of ball that you just selected?___
Don't put your first ball back in the bucket now reach again, no peeking and pick your second ball.( Click the pick a ball icon to simulate reaching into the bucket and select your next ball)
2. What is the probability of selecting the color of ball that you just did_____
3.what is the probability of obtaining your exact sequence of result?____
4. What is your prize____
5. What is your profit from pick a ball___
Answer:
1. The probability of selecting the color of ball that you picked. (White)
The color is white. And total balls are 10
= 4/10
= 0.4
2. After first ball was picked out, you now have 3 whites left and total balls 9. probability of selecting the color of ball that you picked = 3/9
= 0.3333
3. Probability of getting exact sequence
= 0.3333x0.4
= 0.1333
4. The prize = 1/0.1333
= 7.5
5. The price would be 7.5 - 10
= -2.5

What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The area of a rectangular room = 162 square feet
The width of the room = 9 feet.
Now,
Since, we know that;
Area of Rectangle = Length x Width
Let The length of the room = y feet
Substitute all the given values, we get;
The area of a rectangular room = Length x Width
162 = y x 9
Divide by 9, we get;
y = 162 / 9
y = 18 feet.
Thus, The length of the rectangular room will be;
