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={-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.
Hope I helped!

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

Answer:
c
Step-by-step explanation:
Since the image was created by reflecting across the x-axis,
that means that the original triangle was in the fourth quadrant
the image however is in the first quadrant
the coordinates of something in the fourth quadrant is (x, -y)
the coordinates of something in the first quadrant is (x, y)
so the answer is "c" since (x, -(y)) = (x, -y)

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

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.
