The responses to the given question can be defined as follows:
Step-by-step explanation:
Its color palette depends on how much radiation reaches the eyes or the intensity of it. If indeed the duration of a wave is less than 400 nm, it is called UV and much more than 750 nm simple pleasures light it is (IV). The shorter wavelength implies a much more frequent spectrum and lower frequencies are the longer wavelengths.
The shorter the distance, the higher it's indeed. Since the red duration has been longer, the intensity is low. The purple has a smaller range and a high frequency, on the other side. The wavelengths are shorter as well as the frequencies are lower than the red, and it will differ even as violet goes, Remember that even more power is provided with the longer the duration of color. That wave/frequency color rises and is longer the purple color is becoming the lowest color.

Step-by-step explanation:
Given :
__________ no cold ____ cold _____ total
Vitamin C ___ 41 ________ 15 ______ 56
Zinc _______ 12 _________5 ______ 17
Echinacea __ 21 _________ 6 ______ 27
Total ______ 74 _________ 26 ____ 100
The ratio of people who took Echinacea :
Number of people who took Echinacea : total number of people in the survey
From the TOTAL column:
Number of people who took Echinacea = 27
Total Number of people in survey = 100

Answer:
Multiple Choice: 2 Points Each
Short Response: 4 Points Each
Step-by-step explanation:
This is a system of equations problem.
The way I solved it was by, first, organizing two equations.
m(23)+s(10)=86 and m(28)+s(5)=76
m = multiple-choice question points
s = short response question points
The first equation is your scores. m(23)+s(10)=86
You had 23 multiple choice questions and 10 short response questions. Your score on the test was 86.
The second equation is your friend's score. m(28)+s(5)=76
They had 28 multiple choice questions and 5 short response questions. They scored a 76 on the test.
Solve m(23)+s(10)=86;m(28)+s(5)=76
23m+10s=86 for m
Add -10s to both sides.
23m+10s+−10s=86+−10s
23m=−10s+86
Divide both sides by 23.
[tex]\frac{23m}{23}=\frac{-10s+86}{23}[/tex]
m=[tex]\frac{-10}{23} s+\frac{86}{23}[/tex]
Substitute [tex]\frac{-10}{23} s+\frac{86}{23}[/tex] for m in 28m+5s=76.
28m+5s=76
28( [tex]\frac{-10}{23} s+\frac{86}{23}[/tex])+5s=76
Simplify both sides of the equation.
[tex]\frac{-165}{23} s+\frac{2408}{23} =76[/tex]
Add [tex]\frac{-2408}{23}[/tex] to both sides.
[tex]\frac{-165}{23} s+\frac{2408}{23} +\frac{-2408}{23} =76+\frac{-2408}{23}[/tex]
[tex]\frac{165}{23} s=\frac{-660}{23}[/tex]
[tex]\frac{\frac{-165}{23}s}{\frac{-165}{23}}=\frac{\frac{-660}{23}}{\frac{-165}{23}}[/tex]
s=4
Substitute 4 for s in m=[tex]\frac{-10}{23}s+\frac{86}{23}[/tex]
m=[tex]\frac{-10}{23}s+\frac{86}{23}[/tex]
m=[tex]\frac{-10}{23}(4)+\frac{86}{23}[/tex]
Simplify both sides of the equation.
m=2

m=2 and s=4

Given that events A and B are independent with P(A)=0.3P(A)=0.3 and P(A\cap B)=0.27P(A∩B)=0.27, determine the value of P(B)P(B), rounding to the nearest thousandth, if necessary.
Answer:
0.9
Step-by-step explanation:
Since A and B are independent hence;
P(A∩B) = P(A)P(B)
Given the following
P(A∩B) = 0.27
P(A) = 0.3
Required
P(B)
Substitute into the formula;
P(B) = P(A∩B)/P(A)
P(B) = 0.27/0.3
P(B) = 0.9
Hence the value of P(B) is 0.9
The value of P(B) is 0.9
What is probability?Probabilities are used to determine the chances of events
The given parameters are:
P(A) = 0.3
P(A ∩ B) =0.27
To find the value of P(B), we make use of the following formula
P(A ∩ B) = P(A) * P(B)
So, we have:
0.27 = 0.3 * P(B)
Divide both sides by 0.3
P(B) = 0.9
Hence, the value of P(B) is 0.9

Answer: I can’t see the shape
Step-by-step explanation:
but I still we help you if you are finding the area if a rectangle, you multiply the length by width. Like if the rectangle length is 7 and the width is 9 they you multiply it together which you get 63. If you are trying to find a area of a triangle then, duplicate the triangle and try to make a rectangle then caculate area of the rectangle and divide that area by two. Like this photo

PLEASE HELP DUDE. I JUST NEED THE ANSWER .A scuba diver is 356 feet below the surface of the water. The angle of depression the diver makes with her boat is 39degrees
To the nearest foot, how far is the diver from the boat?
A
566 ft
B
176 ft
C
161 ft
The diver is approximately 276.5 feet away from the boat to the nearest foot.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
We can use the tangent function to solve this problem.
Let x be the distance from the boat to the point directly below the scuba diver on the water's surface.
Then we have:
tan(39°) = x/356
Multiplying both sides by 356, we get:
x = 356 tan(39°)
x = 276.5
Therefore,
The diver is approximately 276.5 feet away from the boat to the nearest foot.

A. 0.17
B. 0.47
C. 0.59
D. 0.65
The value of P(A or B) is 0.47. Therefore, option B is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
Given that, P (A) = 0.24, P(B) = 0.41, and P(A and B) = 0.18.
The formula to find P(A or B) is
P(A or B)=P(A)+P(B)-P(A and B)
P(A or B)=0.24+0.41-0.18
= 0.47
The value of P(A or B) is 0.47. Therefore, option B is the correct answer.

Kayla and Mario are playing with a football at the park on a windy day. Mark throws the football straight up in the air, and a gust of wind blows it 10 feet west and 4 feet south from Mark. If [x y] represents the original location of the football, write a matrix that represents the location of the translated ball.
Answer:
|x-10 y-4|
Step-by-step explanation:
Let the initial position where the football is thrown up the air be x and y.
After the ball is thrown up the air it moves 10 feet west 4 feet south because of the gust of wind.
Therefore the change in x is by 10 feet west and is at the point x - 10 and the change in y is by 4 feet south and is at the point y - 4.
Thus the matrix representing the position of the football is |x-10 y-4|.
