Answer:

-2 1/5, -1 2/5, 1/5, |-3/5|, |-1 1/5| ,|-2 2/5|

Step-by-step explanation:

Absolute value means take the positive value

-2 1/5

|-1 1/5| = 1 1/5

|-2 2/5| = 2 2/5

1/5

|-3/5| = 3/5

-1 2/5

We want the numbers from smallest to largest

The most negative is

-2 1/5, -1 2/5

Then to the fractions

1/5, |-3/5|

Then the positive numbers

|-1 1/5| ,|-2 2/5|

a takeaway sells 10 inch pizzas and 12 inch pizzas. what proportion sold were 10 inch pizzas in week 1. What proportion sold wer
wlad13 [49]

Answer:

In week 1, 69.15% of sales were 10-inch pizzas, and the remaining 30.85% were 12-inch pizzas; while in week 2, 71.09% of sales were 10-inch pizzas, and the remaining 28.91% were 12-inch pizzas.

Step-by-step explanation:

Given that a takeaway sells 10 inch pizzas and 12 inch pizzas, to determine what proportion sold were 10 inch pizzas in week 1 and what proportion sold were 10 inch in week 2, the following calculation must be performed:

Week 1 = 736 total sales

10-inch pizzas = 509

736 = 100

509 = X

509 x 100/736 = X

50,900 / 736 = X

69.15 = X

100 - 69.15 = 30.85

Thus, in week 1, 69.15% of sales were 10-inch pizzas, while the remaining 30.85% were 12-inch pizzas.

Week 2 = 1076 total sales

10-inch pizzas = 765

1076 = 100

765 = x

765 x 100/1076 = X

76500/1076 = X

71.09 = X

100 - 71.09 = 28.91

Thus, in week 2, 71.09% of sales were 10-inch pizzas, while the remaining 28.91% were 12-inch pizzas.

lidiya [134]

Answer:

You forgot to put the data

Step-by-step explanation:

Because we  don't have the data that represent the responses to the survery I can show you how to can get the mean and the standard deviation.

The mean is the average of the numbers. We use it to get a representative value of the data we are manipulating.  We calculate it by adding all the numbers and then divide the sum by how many numbers we have.

The formule we use is:

∑\frac{(the data we have)}{of the data}

The standard deviation is a measure of the variation or dispersion of the data we have. A low deviation indicates that our data is few disperced, on the other hand a big deviation indicates a high dispersion of the data.

The formule we use is:

\sqrt{\frac{{∑(x-mean)^{2}}}{{number of data - 1} }  }

The value of x in terms of b is?
charle [14.2K]
To get x in terms of b means that we want an equation where x is alone on one side. We can do that to the given equation:
-2(bx-5)=16
-2bx+10=16
-2bx=6
x=\frac{6}{-2b}
x=-\frac{3}{b}
