Answer:

27 : 100

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

Hence, ratio equals :

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

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

Answer:

m=2 and s=4

Step-by-step explanation:

P = 3a

3a > 45

a > 15

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

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:

|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|.

Answer:

5/11

Step-by-step explanation:

Between numbers 1 - 11, the evens are 2, 4, 6, 8, and 10. Therefore, there are 5 evens.

Out of the eleven choices in the bag, there are 5 possible choices to be picked out of the 11 total choices.

Therefore, the probability of drawing an even number over the number of choices is 5/11.

The value of P(A or B) is 0.47. Therefore, option B is the correct answer.

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.

Answer:

C

Step-by-step explanation:

The diver is approximately 276.5 feet away from the boat to the nearest foot.

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.
