Find the mean of the following set: 30, 16, 29, 14, 21

Answer:

You have to multiply the numbers diagonally not vertically.

So

10x = 7(350)

10x = 2450

x = 245

9514 1404 393

Answer:

Step-by-step explanation:

There is a method of solving proportions that is called "cross multiply" or "cross multiplication". For a proportion like this it looks like each numerator is multiplied by the opposite denominator. In this problem, the result would be ...

  7(350) = (10)x

While "cross multiplication" is a description of the appearance of what is happening, what is really happening is that both sides of the equation are being multiplied by the same value: the product of the denominators. This is in accordance with the multiplication property of equality, which requires you multiply both sides of the equation by the same value.

__

The error that was made in this problem is that each numerator was multiplied by its own denominator. Effectively, that multiplied the left side of the equation by 10² = 100, and the right side of the equation by 350² = 122500. This is in direct violation of the multiplication property of equality, so guarantees the value found for x will be wrong.

__

While "cross multiply" is an instruction often given for solving proportions, it causes an extra step to be needed in solving a proportion like this one. All that is really needed is to multiply both sides of the equation by the denominator under the variable. Here, that means multiplying both sides of the equation by 350.

Correct solution

  [tex]\dfrac{7}{10}=\dfrac{x}{350}\\\\350\cdot\dfrac{7}{10}=350\cdot\dfrac{x}{350}\\\\\\35\cdot 7=\boxed{x=245}[/tex]

Answer:

I believe the two numbers are 14 and 24

Answer:

Those numbers are 14 and 24.

Step-by-step explanation:

You can solve this pretty quickly by taking those two facts and combining them:

a + b = 38

a - b = 10

Let's solve the second one for a:

a = 10 + b

Now we can substitute that into the first one:

a + b = 38

(10 + b) + b = 38

2b + 10 = 38

2b = 28

b = 14

To find a, we can plug that back into one of the original equations:

a + b = 38

a + 14 = 38

a = 24

We can also test our answer by plugging the results into the other given equation and see if we get the same value:

a - b = 10

24 - 14 = 10

10 = 10

So we know our answer is correct.

Question:

A shop is having a sales all items are reduced by 25%. Work out the sale price of an item normally priced at £60?

Answer:

The new price is £45

Step-by-step explanation:

Given

[tex]Sales\ price = \pounds 60[/tex]

[tex]Rate = 25\%[/tex]

First, calculate the reduction

[tex]Reduction = Rate * Sales\ price[/tex]

[tex]Reduction = 25\% * \pounds 60[/tex]

[tex]Reduction = \pounds 15[/tex]

The new price is:

[tex]New = Sales\ price - Reduction[/tex]

[tex]New = \pounds 60 - \pounds 15[/tex]

[tex]New = \pounds 45[/tex]

Step-by-step explanation:

Given

Raju buy an old car for [tex]Rs\ 1,25,000[/tex]

He spent [tex]Rs\ 25000[/tex] on its repair

The selling price of the car  [tex]Rs\ 2,00,000[/tex]

So, the cost price is

[tex]\Rightarrow C.P.=1,25,000+25,000=Rs\ 1,50,000[/tex]

Here, [tex]S.P.> C.P.\quad \text{i.e. gain}[/tex]

Gain percent is

[tex]\Rightarrow \text{Gain percent}=\dfrac{2,00,000-1,50,000}{1,50,000}\times 100=\dfrac{50,000}{1,50,000}\times 100\\\Rightarrow \text{Gain percent}=33.33\ \%[/tex]

A set is a mathematical model for a collection of items. The typical value is greater in Set A, while the spread is greater in Set B.

A set is a mathematical model for a collection of items; it comprises elements or members, which may be any mathematical object: numbers, symbols, points in space, lines, other geometrical structures, variables, or even other sets.

In two of the given sets, the typical value is represented by a triangle, therefore, the typical value in Set A is 7.1..., while the typical value in Set B is 6.

Hence, the typical value is greater in Set A, while the spread is greater in Set B.

Find the gcf, greatest common factor, of 12 and 18 and solve

Step-by-step explanation:

12: 1, 2, 3, 4, 6, 12

18: 1, 2, 3, 6, 9, 18

The gcf is 6, so divide the numerator and denominator by 6.

12 / 6 = 2

18 / 6 = 3

Therefore, 12/18, when relatively prime, is 2/3

Answer: 336 ounces

Explanation: Since each pound in ounces is 16 ounces. (16 ounces is 1lb) which means that when john got his dog it means that his dog weighed 112 ounces. and if you do 112 multiped by 3 it will be 336. so that means that johns dog weighed 336 ounces in the 2 years.

Answer:

3/10 of people vacationed in another state.

Step-by-step explanation:

Because there are 60 people in total, the denominator has to be 60. The numerator then is going to be the amount of people that vacationed in another state. Simplify that fraction by 6, and you will get 3/10 as your answer.

Answer:

[tex]\frac{3}{10}[/tex]

Step-by-step explanation:

Since we want a fraction, we find the total number of people who vaccinated, then we find how many people vacationed in another state.

18+10+5+15+12=60, and 18 people vacationed in another state, we get

[tex]\frac{18}{60}[/tex], and we can divide top and bottom by 2, we simplify to [tex]\frac{3}{10}[/tex]
