UwU your welcome!

Step-by-step explanation:

Convert the mixed fractions to a decimal. 2 1/4 is 2.25 1 2/4 is 1.5 2. Add them up. 3. 3.75 as a decimal or 3 3/4 as a mixed fraction or 15/4 as a improper fraction.

Answer:

a. 5.53

b. 1.078

c. 0.126

d. 0.109

e. 0.549

f. 0.834

g.  0.451

Step-by-step explanation:

The percentage of the flights that arrive on time, P(x) = 79%

The number of flights in the sample, n = 7 flights

a. The mean of the probability distribution, μ = ∑x·P(x)

Therefore, we have; μₓ = n·p

μₓ = 7 × 79/100 = 5.53

b. The standard deviation, σₓ = √(n·p·(1 - p))

∴ σₓ = √(7 × 0.79 × (1 - 0.79)) ≈ 1.078

c. We have;

p = 0.79

q = 1 - p = 1 - 0.79 = 0.21

By binomial probability distribution formula, we have;

The probability of exactly four, P(Exactly 4) = ₇C₄·p⁴·q³

P(Exactly 4) = 35 × 0.79⁴×0.21³ ≈ 0.12625

d. The probability of less than 4 is given as follows;

P(Less than 4) = ₇C₀·p⁰·q⁷ + ₇C₁·p¹·q⁶ + ₇C₂·p²·q⁵ + ₇C₃·p³·q⁴

∴ P(Less than 4) = 1×0.79^0 * 0.21^7 + 7 * 0.79^1 × 0.21^6 + 21*0.79^2*0.29^5+ 85×0.79^3*0.21^4 ≈ 0.109

The probability of less than 4 is ≈ 0.109

e. The probability that more than 5 is given as follows;

P(More than 5) = ₇C₆·p⁶·q¹ + ₇C₇·p⁷·q⁰

7×0.79^6 * 0.21 + 1 * 0.79^7 × 0.21^0 ≈ 0.549

f. The probability that at least 5 of the flight were on time is given as follows;

P(At least 5) = ₇C₅·p⁵·q² + ₇C₆·p⁶·q¹ + ₇C₇·p⁷·q⁰

∴ P(At least 5) = 21×0.79^5 * 0.21^2 + 7×0.79^6 * 0.21 + 1 * 0.79^7 × 0.21^0 ≈ 0.834

g.  For the probability that no more than 5 of the flights were on time, e have;

P(At most 5) = 1 - P(More than 5)

∴ P(At most 5) = 1 - 0.549 ≈ 0.451.

Answer:

Step-by-step explanation:

lateral surface area=(sum of sides)×height

Total surface area =2×base area +lateral area

Answer:

the sides are 6, 20, and 22

Step-by-step explanation:

n + 3n + 2 + 2n + 10 = 48

combine like terms:

6n + 12 = 48

subtract 12 from each side of th equation:

6n = 36

divide both sides by 6:

n = 6

the sides are 6, 20, and 22

Answer:

boys = 272

Step-by-step explanation:

b = boys

g = girls

1) write two equations with the given informations:

g + b = 650

g = b + 106

2) substitute the value of g in the first equation:

b + 106 + b = 650

3) solve the equation for b

2b = 544

b = 272

4) substitute the value in the second equation

g = 272 + 106

g = 378

girls = 378

boys = 272

Answer:

no the solution would be x= 20.

Step-by-step explanation:

50-x=30

-x=30-50

-x=-20

x=20

Answer:

No, x=9 it's not the right solution.

Step-by-step explanation:

Because :if x=9 the equation would be like 50-x=41 and not 30.

But in these case it's like :50-x=30

                                          50-30=20 and not 9.

Answer:

A.78

Step-by-step explanation:

[tex]\frac{30}{25sec}[/tex] -----> [tex]\frac{78}{65sec}[/tex] (scale by 2.6)

You cant get the answer by following these steps.

1. To find out how much we must increase with our scaling we must divide the denominators.

[tex]\sqrt[25]{65}[/tex]= 2.6

2. Then, we do the scaling. Multiply the numerator and the denominator by 2.6.

num- 30 x 2.6= 78.0 (DONT FORGET UR DECIMALS)

dem- 25 x 2.6 = 65

3. Now you have your answer and all you need to do is show it in fraction form as seen below the words "step by step explanation"

Answer:

I think that it is A. 19

Step-by-step explanation:

I think it is A. because 19x2=38. 19-5=14, 14x2=28. 28+38=66.

P=66

L=19

W=14

Each row cannot have the same number of trees.

In mathematics, the term "divisibility" describes a number's ability to be divided by another number in an equal amount without any residue. For instance, it's simple to understand how 40 by 4 can be divided. A huge piece of land that can be divided into smaller chunks and sold separately is said to be divisible, much as it is obvious when you cut into a pan of brownies and distribute equal amounts to each of your friends.

As per the given data:

Number of apple trees = 987

Number of rows = 9

To find whether each row has the same number of trees:

If 987 is divisible by 9 then, the same number of trees can be there else not.

= (987/9) = (329/3) = 109.667

Not divisible, so same number of trees cannot be there.

Hence, each row cannot have the same number of trees.

Answer:

Sale Price = $29.05 (answer). This means the cost of the item to you is $29.05. You will pay $29.05 for a item with original price of $35 when discounted 17%. In this example, if you buy an item at $35 with 17% discount, you will pay 35 - 5.95 = 29.05 dollars

Answer:

  659.52 cm^2

Step-by-step explanation:

In order to find the surface area of this figure, we need to know the dimensions of the base. If we assume the base is square, then the distance from its center to the center of one edge is half the dimension of one side of the base.

That center-to-edge distance (x) can be found from the given dimensions using the Pythagorean theorem.

  x^2 + (15.4 cm)^2 = (17 cm)^2

  x^2 = (289 -237.16) cm^2 = 51.84 cm^2

  x = √51.84 cm = 7.2 cm

This means the edge length of the prism base is 2×7.2 cm = 14.4 cm.

__

The total surface area of the square prism is ...

  A = b^2 +2bs . . . where b is the edge length of the base, s is the slant height

  A = (14.4 cm)^2 + 2(14.4 cm)(17 cm) = 659.52 cm^2

The total surface area of this square pyramid is 659.52 cm^2.
