Answer:

5y + 3 is the sum of the three ages

Step-by-step explanation:

Let y=Mark, d=Daniel j=Jack, and s=The sum

Mark is y years old. In five years jack will be twice as old as Mark

j + 5 = 2(y+5)

j + 5 = 2y + 10

j = 2y + 10 - 5

j = 2y + 5

Daniel will be two years younger than jack is now

d + 5 = j - 2

d = j - 2 - 5

d = j - 7

Replace j with (2y+5)

d = (2y+5) - 7

d = 2y - 2

Expression in terms of y for the sum of the 3 ages now

s = y + j + d

replace j and d with expressions we came up with above

s = y + (2y+5) + (2y-2)

s = y + 4y + 3

s = 5y + 3 is the sum of the three ages

The original cost of the item, given the cost to the store and the markup, can be found to be $ 200

Given that the cost to the store is $ 160 and they would charge a  25 % markup on this cost, the original cost can be denoted as x and the formula would be:

x = Cost to store x ( 1 + markup percentage )

The original cost to the customer would then be:

= 160 x ( 1 + 25 %)

= 160 x 1 .25

= $ 200

The original cost charged by the store to the customer is $ 200.

Answer:

\(S = \{A, B, AB, O\}\)

Step-by-step explanation:

Given

Blood groups: A, B, AB and O

\(n = 1500\)

\(A = 438\)

\(B = 350\)

\(AB = 95\)

\(O = 617\)

Required

The sample space for blood type

To determine the sample space, we will consider the blood groups being sampled

So, the sample space is:

\(S = \{A, B, AB, O\}\)

And the sample size is:

\(Size = n(S)\)

\(Size = 4\)

Step-by-step explanation:

Blood groups: A, B, AB and O

n = 1500n=1500

A = 438A=438

B = 350B=350

AB = 95AB=95

O = 617O=617

Required

The sample space for blood type

To determine the sample space, we will consider the blood groups being sampled

So, the sample space is:

S = \{A, B, AB, O\}S={A,B,AB,O}

And the sample size is:

Size = n(S)Size=n(S)

Size = 4Size=4

Answer:

The 9th term of the given sequence is 78732.

The given sequence is 12, 36, 108... is a geometric sequence with a common ratio of 3.To find the 9th term of the given sequence, we will use the formula for the nth term of a geometric sequence, which is given by:

aₙ = a₁rⁿ⁻¹

Here, a₁ = 12 and r = 3.

Therefore, the formula for the nth term becomes:

aₙ = 12(3)ⁿ⁻¹

Now, we need to find the 9th term of the sequence. Hence, n = 9. Substituting the values of a₁ and r, and n in the formula, we get:

a₉ = 12(3)⁹⁻¹= 12(3)⁸= 12(6561)= 78732

Answer:

Option A is correct.

The surveys are biased because people chose to respond or not.

Step-by-step explanation:

When humans are given the choice whether to participate in a poll like in this question, most often than not, the poll is biased.

This is because only the people or set of people who feel strongly the most about the subject matter of the poll will participate in the poll. This favours the group that disagrees as this group, if given the choice to express their opinion, will most likely be the set of people that will readily express their discontent.

Discontent is more visibly and strongly expressed in humans.

In order to remove this bias, people should have been chosen at random and their responses recorded.

The two other options are not absolutely correct, these are the reasons.

b. Because of the large sample size, the results are most accurate of all members of the community.

Like I expressed above, the base of the sample is flawed and biased as it will most likely favour a group of the population that don't agree with the law. So, no matter how large the sample is, that type of bias makes the poll unreliable.

c. The same sampling methods were used for both polls, demonstrating reliability.

The sampling method is biased, so, it doesn't matter if it is repeated for both polls. it most likely will not represent the correct general consensus about the new traffic law.

The value of angle x in the triangle is 5

The given parameter is represented by the figure

By the external opposite angle of a triangle theorem, we have the following equation

22x + 3 = 6x + 4 + 79

Collect the like terms

So, we have

22x - 6x = 4 + 79 - 3

Evaluate the like terms

So, we have

16x = 80

Divide both sides by 16

So, we have

x = 5

Hence, the value of angle x in the triangle is 5

a) The area of the rectangular shaped bathroom floor is A = 30.375 feet²

b) The number of boxes of tiles = 25 boxes

Given data ,

Jordan is putting new tile on the bathroom floor. The width of the floor is 4 2/4 feet and the length is 6 3/4 feet

Now , Area of Rectangle = Length x Width

On simplifying , we get

Width = 4 2/4 feet = (4 x 4 + 2)/4 = 18/4 feet

Length = 6 3/4 feet = (6 x 4 + 3)/4 = 27/4 feet

Area = (18/4) x (27/4) = (18 x 27)/(4 x 4) = 30.375 feet²

Therefore , the area of bathroom floor is A = 30.375 feet²

Now , the number of boxes is given by

Number of boxes of tiles = Total area of bathroom floor / Area covered by each box of tiles

B = 30.375 / 5

B = 6.075

B = 6 tiles

Hence , the area of bathroom floor is A = 30.375 feet²

Answer:

6 liters of diet cola.

Step-by-step explanation:

In order to find the answer to this question you have to find the price per liter of diet cola.

To do this you will have to take $10 and divide it by 4.

10/4 = 2.5

Each liter costs $2.50.

Next, to get the number of liters you can buy, you will take $15 and divide it by $2.50.

15/2.50 = 6

Therefore, the number of liters of diet cola you can buy for $15 is 6.

The radius of the bigger sphere is 30cm.

Two spherical solids have masses of 15g and 405kg respectively

Mass is directly proportional to volume for same metal (Density)

Let Mass of Solid 1 be M₁ and Volume be V₁

Mass of Solid 2 be M₂ and Volume be V₂

Now  M₁/M₂ =  V₁/V₂

Volume of sphere is directly proportional to R³

So,  M₁/M₂ = V₁/V₂ = R₁³/R₂³​

15/405000 = 10³/x³

∛15/∛405000 = 10/x

2.466/73.986 = 10/x

2.466x = 73.986 x 10

x = 739.86/2.466

x = 30

Therefore, the radius of the bigger sphere is 30cm.

The Venn Diagram is shown at the end of the answer.

Then the amounts are given as follows:

The Venn Diagram is filled starting at the intervals involving most variables, that is, the intersections.

286 students took all three courses, hence:

V = 286.

629 students were taking history and dance, hence:

VI + V = 629

VI + 286 = 629

VI = 343.

605 students took history and math, hence:

IV + V = 605

IV = 605 - 286

IV = 319.

604 students took dance and math, hence:

II + V = 604

II = 318.

1236 students took dance, hence:

III + II + VI + V = 1236

III + 318 + 343 + 286 = 1236

III = 1236 - (318 + 343 + 286)

III = 289

1295 students took math, hence:

VIII + IV + V + VI = 1295

VIII + 319 + 286 + 343 = 1295

VIII = 1295 - (319 + 286 + 343)

VII = 347

1174 students took history, hence:

I + II + IV + V = 1174

I + 318 + 319 + 286 = 1174

I = 1174 - (318 + 319 + 286)

I = 251
