In your biology class, your nal grade is based on several things: a lab score, scores on two major tests, and your score on the nal 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 nal exam is worth 30%. Compute the weighted average for the following scores: 92 on the lab, 81 on the rst major test, 93 on the second major test, and 85 on the nal exam. (
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]
If Audrey wanted to solve this equation using the square root method, which answer shows the correct sequence of steps?
x2 + 5 = 41
a. Take the square root of both sides
b. Subtract 41 from both sides, then square root both sides.
c. Subtract 5 from both sides, then square root both sides.
d. Add 5 to both sides, then square root both sides
Answer:
C
Step-by-step explanation:
subtract 5 from both sides

Please help omg. ASAP.
Answer:
We have to find the equation of the red line
To get the equation of the line in the slope-intercept form,
we need its slope and its y-intercept
Finding the Slope
we know that the slope of a line is the rise of the line / run of the line between 2 points
here, the 2 points are already marked on the graph
So, slope = rise / run
we notice that the line rises only 2 units and runs 8 units between the points: (-5 , 3 ) and (3 , 5)
Slope = rise / run
now that we know the values of rise and run, we can plug the values to get the slope
Slope = 2 / 8
Slope = 1 / 4
Finding the y-intercept
We will now look at the point (-5 , 3) , we know that the slope is 1/4.
which means that every time the line moves 1 unit to the right, it also moves 1/4 units up
So, until the point (-1 , 4), the line has finally ascended 1 unit and now is at a proper coordinate
We can see that the line is only 1 unit to the left of the y-axis, so the y-coordinate of the line after moving 1 unit to the right is the y-intercept
since the line ascends 1/4 units every time it moves 1 unit to the right,
the ordinate of the line at the y-axis will be 1/4 more than the last ordinate (which was 4)
y-intercept = (4 + 1/4)
y-intercept = 17 / 4
Equation of the line
From the question, we know that the general form of the slope-intercept form is :
y = mx + b (where m is the slope and b is the y-intercept)
y = (1/4)x + (14/4)
y = (x + 14) / 4

A line contains the points (6, 8) and (1,-2).
What is the slope of the line in simplified form?
Enter your answer in the box
Answer:
The slope of the line is two.
Step-by-step explanation:
Recall that to find the slope between any two points, we can use the slope formula:
[tex]\displaystyle m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Let (6, 8) be our (x₁, y₁) and let (1, -2) be our (x₂, y₂). Substitution yields:
[tex]\displaystyle m=\frac{(-2)-(8)}{(1)-(6)}[/tex]
Subtract:
[tex]\displaystyle m=\frac{-10}{-5}[/tex]
Divide:
[tex]m=2[/tex]
Therefore, the slope of the line is two.

si un submarino esta a - 83 metros a nivel del mar, sube a -15 cuantos metros subio?
Answer:
El submarino subió 68 metros
Step-by-step explanation:
Desplazamiento
Si un cuerpo cambia de posición desde X1 hasta X2, su cambio de posición se calcula como:
X=X2-X1
En el caso de nuestro submarino, su posición original era a X1=-83 m, luego sube a la posición X2=-15 m, así que su cambio de posición o desplazamiento es:
X=-15-(-83)=-15+83=68 m
El submarino subió 68 metros
A={-6, 0, 6},
B={-1, 0, 1}
find A intersect B
Answer:
[tex] \huge \boxed{ \sf{ \{ 0 \} }}[/tex]
Step-by-step explanation:
Given :[tex] \sf{A} \: = \: [/tex] { -6 , 0 , 6 }
[tex] \sf{B} \: = [/tex]{ -1 , 0 , 1 }
To find :A ∩ B
Solution :A ∩ B = { -6 , 0 , 6 } { -1 , 0 , 1 }
A ∩ B = { 0 }
Remember : In case of intersection , the common element of two sets A and B should be listed in a single set. So, the intersection of sets A and B is the set of all elements which belong to both A and B. The intersection of sets A and B is denoted by ( A ∩ B ) and read as A intersection B.

A paddle board rental company has two different rental options. Option 1 - Pay a yearly membership fee of $120 and then pay $10 each time you want to rent a board. Option 2 - Pay no membership fee and then pay $18 each time you want to rent a board. Which equation can be used to find x, the number of times rented so that the two options are equal in cost? (8.8B) *
1 point
10x = 120 + 18x
120 + 10x = 18x
120x = 10 + 18
10x + 18x = 120
Answer:
option b - 120+10x=18x
Step-by-step explanation:$120 is yearly and $10 is multiplied by x - how many times you want to rent
and then 18 is how much you pay for x times you want to rent it
sam can make 18 burritos in 8 min write the ratio that compares the time to the number of burritos simplify if possible
Answer:
Ratio time to the number of burritos = 4:9
Step-by-step explanation:
Given:
Number of burritos make = 18
Total time taken = 8 min
Find:
Ratio time to the number of burritos
Computation:
Ratio time to the number of burritos = Total time taken / Number of burritos make
Ratio time to the number of burritos = 8 / 18
Ratio time to the number of burritos = 4 / 9
Ratio time to the number of burritos = 4:9
