Step-by-step explanation:

add up all of the numbers in the five groups then divide the numbers by the number of numbers you have for example if the sum of all of those numbers is let's a 25 and you have 5 numbers you'll divide 25 by 5 and your men will be 5:00 and if the sum of the numbers was 30 and you have six numbers you'll / 30by6 then your answer then the mean will be six

Answer:

I don't know which school you are asking for, so here are all of them, followed by the general mean of all the schools.

a: 1.7

b: 4.7

c: 3.9

d: 5.3

e: 4.5

gen: 4

Step-by-step explanation:

This is easiest to solve with a calculator.

When finding the mean, you need to add all the numbers together, then divide by how many numbers you added.

Let's say that you have the numbers 2, 5, and 8. You add them together to get 15, then divide 15 by 3. The mean is 5.

With your problem, the general mean of all 5 schools is 4.

Hope that this helps!

Consequently, the answer to the above fraction problem comes out to be 1/2 .

An element of a fraction or ratio is a piece of a whole. The number of equally sized pieces into which the whole has been divided is represented by the denominator b, and the number of parts that are included is represented by the numerator a. The LCM of two fractions' denominators is the least common multiple (LCD) of those denominators.

Here,

Given here is: (4√(2) - √(2)) × √(2) /  (2) (2) × √(18) (18)

The radical is then simplified in order to determine its value.

=> 3√(2) × √(2) / 2√(2) × 3√(2)

=> 3(2) / 6(2)

=> 3/6

=> 1/2 or 0.5

so,

after simplification, the answer is 1/2.

Consequently, the answer to the above fractional problem comes out to be 1/2 .

Step-by-step explanation: So when he got the milk he got stuck in traffic for a long time which caused the milk to expire and so he went back to grab new milk and on his way home he was stuck in traffic again and the milk got expired so he repeats the process and the same thing happens over and over and over, so hes stuck in an infinite loop until he passes away.

Answer:

x° = 48°

Step-by-step explanation:

In order to solve this, we need to know that the sum of all inner angles of the triangle is equal to 180°. Based on this diagram we know that...

180° = 90° + 42° + x°

From here we know that...

x° = 180° - 90° - 42°

x° = 48°

The equation y^ = -2.5x + 222.5 models the amount of cholesterol, LDL, for a person in mg/dl, where x is the time spent exercising per day in minutes.

What in mathematics is a quadratic equation?

Definitions: x ax2 + bx + c = 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. a 0. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.

To find the amount of cholesterol for a person exercising 20 minutes a day, we need to substitute x = 20 into the equation:

y^ = -2.5(20) + 222.5

Solving this equation, we get:

y^ = -50 + 222.5

y^ = 172.5

So, the amount of cholesterol for a person exercising 20 minutes a day is 172.5 mg/dl.

Therefore, the answer is 172.5 mg/dl

Answer:

180 degrees

Step-by-step explanation:

Answer:

Two angles are called supplementary when their measures add up to 180 degrees.

Step-by-step explanation:

Hence, any two angles can be supplementary, if their sum equal to 180°.

...

Difference between Complementary and Supplementary Angles.

Complementary Angles: Supplementary Angles:

Sum of two angles is 90° Sum of two angles is 180°

Therefore, K= 66 degrees, LK length = 22 unit, and LK length = 22 unit are the answers to the specific problem of angles.

A geometrical angled construction is constructed from two rays that converge at the summit, or center, of both the angle and are referred to as the face and the vertex, respectively. Guess it depends on how they're situated, it is possible for two rods to create an angle together within plane. When two planes collide, an inclination is also formed. Diahedral angles are the term used to refer to them. Light beams or lines in euclidean geometry can have a wide variety of shapes or angles for the same termination. The phrase "angle" in English is based on the Latin term "angulus," which meaning "horn." the vertex.

Here,

Given: MKL M = 24 degree right triangle

K is 90 degrees, etc.

Thus,

=> ∠L + ∠M +∠K =180

=> 90 + 24 + ∠K = 180

=>∠K =180-114

K equals 66 degrees.

and

The formula for LK length is 22.

The formula for LK length is 22.

In light of this, the answer to the angle problem is

K=66 degrees, and LK length=2 units. LK length equals two units.

The number of hours after which the cars will be 350 miles apart is 34 hours.

Speed is the ratio of distance and time.

It shows how fast an object is moving at a given time.

We have,

Vehicle 1.

Speed = 55.5 mph

Distance(1) = 55.5 x Time

Vehicle 2.

Speed = 45(1/4) mph

Distance(2) = 45(1/4) x Time

The difference in the distance = 350 miles.

Distance(1) - Distance(2) = 350

55.5 x Time - 45(1/4) x Time = 350

55.5 x Time - (181/4) x Time = 350

(55.5 - 181/4) x Time = 350

Time = 350 / (55.5 - 45.25)

Time = 350 / 10.25

Time = 34 hours.

Thus,

The car will be 350 miles apart after 34 hours.

Answer:

41x² - 27x + 27

Step-by-step explanation:

Perimeter of Rectangle:

= 2(20x²-12x+4) + 2(5x²-5x+15)

= 40x²-24x+8 + 10x²-10x+30

= 50x²-34x+38

Perimeter of Triangle:

Answer:

(6, 5 )

Step-by-step explanation:

3x + 2y = 28 → (1)

5x - 3y = 15 → (2)

multiplying (1) by 3 and (2) by 2 and adding the result will eliminate y

9x + 6y = 84 → (3)

10x - 6y = 30 → (4)

add (3) and (4) term by term to eliminate y

19x + 0 = 114

19x = 114 ( divide both sides by 19 )

x = 6

substitute x = 6 into either of the 2 equations and solve for y

substituting into (1)

3(6) + 2y = 28

18 + 2y = 28 ( subtract 18 from both sides )

2y = 10 ( divide both sides by 2 )

y = 5

solution is (6, 5 )

What is Chebyshev's theorem?

The minimum percentage of observations that are within a given range of standard deviations from the mean is calculated using Chebyshev's Theorem. Numerous other probability distributions can be applied to this theorem. Chebyshev's Inequality is another name for Chebyshev's Theorem.

Here,

we have a sample size of n = 40.

The mean number of pets per household is 2 and the standard deviation is 1.

We need to determine at least how many of the households have 0 to 4 pets.

By using Chebyshev’s inequality rule with k = 2(that is ) then,

= 100(1- (1/k²))%

= 100 (1- (1/2²))%

= 100 (1- (1/4))%

= 75%

The corresponding number of households is the percentage multiplied by the sample size.

= 75% × 40 = 30

Hence, at least 30 of the households have 0 to 4 pets.
