Using measures of center and variability to compare data- quiz answers?

Answer:

0.08

Step-by-step explanation:

5 ^-2 * cube root of 8

first of all, let us solve 5^-2

using the law of indices;

a^-2 = 1 / a ^2

following this law, we have;

5^-2 = 1 / 5^2

we know that 5^2 = 25

therefore,

5^-2 = 1 / 25

now, let is continue by solving the cube root of 8

now, there are three ways of solving this;

we could just simply think of any number that when multiplies itself three times times, it gives 8, or we could just simply use a calculator

regardless of what we use, we have to end up with the number 2 as the answer

leading is to our conclusion.

from all our solution, we have reduced our question to;

1 / 25 ( which is 5^-2) * 2 ( which is the cube root of 8 )

= 1 / 25 * 2 / 1

note that 2 is the same as 2 / 1. We put it like this when we want to carry out an operation on an integer ( e.g. 2) and and a fraction ( e.g. 1 / 25 )

so,

1 / 25 * 2 / 1 =

2 / 25 ( the two multiplies the 1 in 1 / 25 and the 25 multiplies the 1 in 2 / 1)

leaving our answer in decimal, we have;

0.08

Todd I think if I'm wrong sorry

Answer:

48

Step-by-step explanation:

25x4.8=120

10×4.8=48

I got 4.8 by doing this:

I already knew that 25×5 would equal 125.

but since they wanted 120, I instead multiplied 25 by 4 with decimals from 1-10 until I got 120, then I multiplied that with the 10 pages to get my answer.

Answer:

Step-by-step explanation:

Is 1.450 correct?  145 would make more sense.  I'd even go with 1,450, just for a laugh.  I'll assume 1.450 is the correct number here.  I'll assume assute the question eventually asks how old are A and B.

A = 49(B)

A+B=1.450

Substitute:  

49B+B=1.450

50B = 1.450

B = 0.029

A = 49(B)

A = 49*(0.029)

A = 1.421

let's solve :

Range:15

Mean:86

Median:86

Mode:86

Answer:

15, 89, 86, 86

Step-by-step explanation:

To find the range of any data, follow the steps

Step-1: Arrange the set of data in ascending order.

Step-2: Divide the smallest value from highest value. Means, highest value - smallest value.

= 79, 83, 84, 86, 86, 90, 94

= 94 - 79

= 15

To find the mean of any data, follow the steps

Step-1: Add all the numbers.

Step-2: Divide the result by the numbers of observation.

= (79 + 83 + 94 + 86 + 90 + 84 + 86) ÷ 7

Here, we divide it by 7 because, there are 7 numbers in the data.

= 602 ÷ 7

= 86

To find the median of any data, follow the steps

Step-1: Arrange the numbers(given in data) in ascending order.

Step-2: Find the middle number in the set.

= 79, 83, 84, 86, 86, 90, 94

Now, find tee middle number in it.

= 86

See in last, to know, what will be the median, if there will be 2 numbers in the middle.

To find the mode in any data, see that which number is occurring the most.

In this set of data, 86 is occurring the most number of times from others.

= 86

Mode can be more than 1 in a set of data. So, don't get confused that what will be the mode, if you find more than 1 mode in a set of data.

what will be the median, if there will be 2 numbers in the middle?

There will be only 1 median in a set of data.

To know the median if there are two numbers in the middle, just remember the steps which is written down.

Step-1: Add both the middle numbers.

Step-2: Divide the result you get after adding.

For example, to find the median in 79, 83, 94, 86, 90 and 84.

First we need to arrange them in ascending order.

After arranging them in ascending order we will get the result, 79, 83, 84, 86, 94, 90.

So, here there are two numbers in the middle that are 84 and 86.

So, add them and divide it by 2.

= (84 + 86) ÷ 2

= 170 ÷ 2

= 85 is our final answer.

Hope, now you know how to find median if there are two numbers in middle.

Answer:

4

Step-by-step explanation:

0.25x + 7 = 4(x-2)

0.25x + 7 = 4x - 8

0.25x - 4x = -7 - 8

-3.75x = -15

3.75x = 15

x = 4

Evaluating the expression, [tex]-5(-10-2(-3))2[/tex] is equal to 40.

Given the following expression:

To evaluate the given expression, we would apply BODMAS:

In this exercise, you're required to evaluate the given expression by simplifying it to its simplest form. Thus, we would have to apply BODMAS in order to achieve this.

In Mathematics, BODMAS is an abbreviation for the following:

Dealing with the brackets, we have:

[tex]-5(-10+6)2\\\\-5(-4)2\\\\20 \times 2 = 40[/tex]

Therefore, we have:

Step-by-step explanation:

Have a good day

The loan repayment is an illustration of a linear function.

He will finish paying the loan after 6 months.

A linear function is illustrated as: [tex]\mathbf{y = mx + b}[/tex]

In this case:

Because the amount reduces after each monthly payment, the value of m will be taken as: m = -325

So, we have:

[tex]\mathbf{y = -325x +1950}[/tex]

When he finishes paying the loan, we have: y = 0.

So, the equation becomes

[tex]\mathbf{0 = -325x +1950}[/tex]

Add 325x to both sides

[tex]\mathbf{325x =1950}[/tex]

Divide both sides by 325

[tex]\mathbf{x =6}[/tex]

Hence, he will finish paying the loan after 6 months.

Answer:

Step-by-step explanation:

first you would want to flip the equation then multiply 9 on both sides to get

5(F-32)=9C

Then you would want to divide both sides by 5 which crosses out the 5 from the equation and is moved to the other side which then were you simplify getting

F-32=9C/5

Lastly you want to add 32 to both sides causing - 32 to cross out getting

F=9C/5 +32

making F=9C/5 + 32 our answer

a) Solution for x:

x = {x / -3 ≤ x ≥ 2; x≠-2;1)

Interval notation:

(-∞, -3] ∪ (-2, 1) ∪ [2, +∞)

Step-by-step explanation:

Rational Inequality is inequality with rational numbers or expressions.

The symbols in inequality are:

Less than (<)

Greater than (>)

Less than or equal to (≤)

Greater than or equal to (≥)

In fraction or rational expression, the denominator is not 0. A zero-denominator renders the expression undefined.

Given:  

(x+3)(x-2)/(x+2)(x-1)≥0

The rational expression:

Numerator:  (x+3)(x-2)

Denominator:  (x+2)(x-1) where x ≠ -2 and x ≠ 1 because the values -2 or +1 will make the expression undefined

Find the solution for x by equation the factors in enumerator to 0:

x+3 ≥ 0  

x ≥ -3

x ≤ -3

x - 2 ≥ 0

x ≥ 2

But:

x ≠ -2

x ≠ 1

Hence:

Solution for x:

x = {x / -3 ≤ x ≥ 2; x≠-2;1)

Interval notation:

(-∞, -3] ∪ (-2, 1) ∪ [2, +∞)

------------------------------------------

b) Take the root of both sides and solve

Inequality Form:

− 4 ≤ x < 2  or  x ≥ 3
