Answer:

The mean is 82.727272727273 rounded 83

Step-by-step explanation:

You add all the numbers:

40 + 75 + 80 + 80+ 81 + 84 + 88 + 90 + 92 + 100 + 100= 910

You divide that result by the total of numbers to add, in this case 11

910/11= 82.727272727273

To round any number, consider that if it is 5 or above it you can round it to the nearest hundred.

Answer:

-5 turns into 5 and the y is probably 1, so 5+9 is equal to 14.

Step-by-step explanation:

A soldier is parachute training. he jumps out of the plane high enough that the pilot determines the soldier will land somewhere in a 240-foot radius, the geometric probability that the soldier will land in a tree is approximately 0.0332, or 3.32%.

A = π\((240)^{2}\)

= 180,955.27 square feet

A = π\((8)^{2}\)

= 64π square feet

=30 × 64π

= 1920π square feet

Finally, we can find the probability that the soldier will land in a tree by dividing the area of the circles around the trees by the area of the landing zone:

P(landing in a tree) = (1920π) / 180,955.27

≈ 0.0332

The probability that a child is not allergic to nuts is 0.986, or 98.6%.

The probability that a child is not allergic to nuts can be calculated by subtracting the probability of being allergic to nuts from 1.

Given the probabilities of a child being allergic to nuts, dairy, and gluten, we are interested in finding the probability that a child is not allergic to nuts.

The probability of being allergic to nuts is given as 0.014.

To find the probability that a child is not allergic to nuts, we subtract this value from 1.

P(Not allergic to nuts) = 1 - P(Allergic to nuts) = 1 - 0.014 = 0.986

Therefore, the probability that a child is not allergic to nuts is 0.986, or 98.6%.

This calculation is based on the assumption that being allergic to nuts and being allergic to other foods are independent events.

Answer:

3/4 year = 9

Step-by-step explanation:

To find 3/4 of a year you first need to find 1/4 of a year so you do 12/4 and get 3. Now we know that 1/4 of a year is 3 months so you just multiply that by 3 to get 9. So 3/4 of a  year is 9 months.

I hope this helps!

Your answer to 3/4 of a year is 9 months

The two outliers in the scatter plot below are the points with shoe size 5 and shoe size 12.

These outliers are likely due to the fact that the data set includes people of all ages, and shoe size is not a linear function of height. For example, a 5-year-old child is likely to have a shoe size of 5, even though they are much shorter than an adult with a shoe size of 5. Similarly, an adult with a shoe size of 12 is likely to be much taller than a child with a shoe size of 12.

In order to get a more accurate representation of the relationship between height and shoe size, it would be necessary to remove the outliers and only consider data from people of similar ages.

Answer:

x = 9

Step-by-step explanation:

You need to use PEDMAS (Parentheses, exponents, division, multiplication, addition, subtraction) to solve the equation.

1.) Begin by multiplying the values inside of the parentheses by the (-3).

2.) Isolate the variable by adding (15) to both sides.

2.) Isolate the variable by subtracting (2x) from both sides.

Answer:

l = 40 m

Step-by-step explanation:

The formula for area of a rectangle is

A = lw, where

Step 1:  Since we're given the area and width, we plug in these two values for A and w and to solve for l (length):

360 = 9l

Step 2:  Divide both sides by 9 to solve for l

(360 = 9l) / 9

40 m = l

Optional Step 3:  We can check our answers by checking that the product of 40 and 9 is 360

40 * 9 = 360

Answer:

The two numbers are 40, and 27.

Explanation:

Since there are only two numbers, with two different aspects, you can just make

a system, and solve.

A sum of two numbers adding up to 67 can be modeled by: x + y = 67.

A difference of those same two numbers being 13 can be modeled by: x – y = 13.

You can add the two equations together to eliminate the y value because the -y and y will cancel out:

x + y = 67.

+ x – y = 13.

And you get: 2x = 80.

Now to find x, just divide by 2 on both sides to cancel out the coefficient of 2 in 2x:

2x = 80

÷2 ÷2

x = 40.

So the first number is 40.

Since we know the first number, we can immediately find the other number by substituting it into the first equation.

x = 40 → x + y = 67

(40) + y = 67

-40. -40

Subtract from both sides to cancel the constant terms.

Then you will get that y or the second number is y = 27.

This is true because 40 + 27 = 67, and 40 - 27 = 13.

The product of the given value is zero.

Multiplication is a basic arithmetic operation in mathematics which involves combining two or more numbers to obtain a result called the product. The operation involves repeated addition or the combining of equal groups to determine a total quantity.

For example, 2 times 3 equals 6, which means combining two groups of three items results in a total of six items. Multiplication is denoted by the "×" symbol or by placing numbers adjacent to each other, such as 2(3) or 2×3.

Given value is;

7x7x8x8x99x0x5x5x666x444

Here in between we can see, there is a zero value and e know that the multiplication of any number multiplied by 0 is always 0.

So, the product of the given value is zero.

You are approximately 161.5566 feet away from the base of the tree.

To determine the distance from the base of the tree, we can use trigonometry and the concept of tangent.

Let's denote the distance from the base of the tree as "x."

We have a right triangle formed by the tree, the distance from the base, and the angle of elevation. The opposite side of the triangle is the height of the tree, which is 280 feet, and the adjacent side is the distance from the base, denoted as "x."

Using the tangent function, we have:

tan(60°) = opposite/adjacent

tan(60°) = 280/x

To solve for x, we can rearrange the equation:

x = 280 / tan(60°)

Using a calculator, we can evaluate the expression:

x ≈ 280 / 1.7321 ≈ 161.5566

The complete question is "If the train was traveling nonstop at speed of 50 mph, how many miles would Smith

and Annie have traveled in 5.5 hours ?"

Let us solve right hand side and make it equal to left hand side .

Given expression,

cot2B = (cos B - sinBtanB) / secBsin2B

Basic trigonometric functions,

tanB = sinB/cosB

cotB = cosB/ sinB

secB = 1/cosB

sin2B = 2sinBcosB

cos²B - sin²B = cos²B

Now,

LHS = (cos B - sinBtanB) / secBsin2B

Further,

= (cosB - sinB×sinB/cosB) / secB 2sinBcosB

= (cos²B - sin²B) / cosB × 1/ cosB × 2sinBcosB

= (cos²B - sin²B) / sin2B

= cos2B / sin2B

=cot2B

Hence proved.

Thus with trigonometric identities we can prove LHS = RHS.
