0.4

Explain:

Each fraction can be turned into a decimal and a percent.

To figure that out you can either divid your fraction (numerator divided by denominator) or you can see 2/5 which is equal to 4/10. And 4/10 is 40% or 0.4.

You could also see that 40 squares are coloured out of 100 of them so you can find out 40 divided by 100 is 0.4.

I hope this not only helps you figure out the answer but also know how to get the answer any other time you have a question like this.

First you divide them all by 7 to see which are greater than 19

28/7=4
84/7=12
35/7=5
105/7=15

even if you add 1 to them they all are still less than 19
so select them all

hope this helps! :)

Does anyone know how to do this

Considering the area of the rectangle, we have that the length is of 8 units and the width is of 10 units.

<h3>What is the area of a rectangle?</h3>

The area of a rectangle of length l and width w is given as follows:

A = lw.

In this problem, the area is of 80 square units, while the length and the width are consecutive even integers, hence:

A = 80.

w = l + 2.

Then:

l(l + 2) = 80

l² + 2l - 80 = 0

(l + 10)(l - 8) = 0.

We need the positive measure, hence:

l - 8= 0 -> l = 8 units.

w = l + 2 = 10 units.

Does the budgeted amount cover the actual amount for expenses, savings, and emergencies? a) no, it's short $207.00. b) no, it's

Korvikt [17]

The expense amount is more than the savings amount. No, it's short $207 then the correct option is A.

<h3>What are statistics?</h3>

Statistics is the study of collection, analysis, interpretation, and presentation of data or to discipline to collect, and summarise the data.

From the table, we have

The amount of the savings will be

Saving amount = $ 20

Then the amount of the expense will be

Expense amount = 150 + 75 + 2 = 227

Then the budgeted amount covers the actual amount for expenses, savings, and emergencies will be

→ savings amount - expense amount

→ 20 - 227

→ $ 207

Thus, the expense amount is more than the savings amount. No, it's short $207.

More about the statistics link is given below.

Do one of the following, as appropriate. (a) Find the critical value z Subscript alpha divided by 2, (b) find the critical v

babymother [125]

Answer:

We want to construct a confidence interval at 99% of confidence, so then the significance level would be $1-0.99 =0.01$ and the value of $\alpha/2 =0.005$ . And for this case since we know the population deviation is not appropiate use the t distribution since we know the population deviation and the best quantile assuming that the population is normally distributed is given by the z distribution.
