Answer: The answer is 0.20

Step-by-step explanation: To find a scale factor all you need to do is find the ratio of a side on the scaled shape to its corresponding side on the original figure. We know the bottom of the scaled figure is 0.5 and the same side on the original rectangle was 2.5 so we can just divide like so...

0.5/2.5 = 0.2 which is our correct answer. I hope this has been of use to you :) If you have any other questions please do not hesitate to ask!

The ratio of teachers to students at Priory School is 2:27

What is school's total population if there are 42 staff

Answers

Answer:

609

Step-by-step explanation:

ratio of teachers to students at Priory School =2:27

Let X= total number of both the students and the teacher

Ratio of teacher=( 2/29)X

Ratio of student is (27/29 )X

But total number of teacher = 42

2/29 ×X =42

2X= 42×29

2X=1218

X= 609

Hence, school's total population is 609

1138 in expanded form

Answers

One thousand one hundred thirty eight

Answer:

(see below)

Step-by-step explanation:

To put 1138 in expanded form, you should first know that expanded form is separating a number into its place values. Here's what I'm talking about:

1 in expanded form is 1.

11 in expanded form is (10 + 1).

111 in expanded form is (100 + 10 + 1).

So that means that:

1138 in expanded form is (1000 + 100 + 30 + 8).

Suppose that 20% of students at high school A and 18% of students at high school B participate on a school athletic team. Independent random samples of 30 students from each school are selected and asked if they participate on a school athletic team. Let ˆ p A represent the sample proportion of students at school A who participate on a school athletic team and ˆ p B represent the sample proportion of students at school B who participate on a school athletic team.

What is the mean of the sampling distribution of ˆ p A − ˆ p B ?

Answers

Answer:

0.02

Step-by-step explanation:

High schools A :

Percentage of participants in on the school athletic team = 20%

Pa = 20% = 0.2

High school B:

Percentage of participants in on the school athletic team = 18%

Pa = 18% = 0.18

The mean of sampling distributon is :

Pa - Pb

0.2 - 0.18

Hence, Mean of sampling distribution is 0.02

can someone please help me graph y=2/3x-4

Answers

Answer:

Look at the picture attached.

Step-by-step explanation:

Your x-intercept is 6 and your y-intercept is 4, that is where your 2 points will go. According to the slope, you should go up 2 and over 3, if you don't want to find the x-intercept. Then you would just plot the y-intercept which is 4, and then go up 2, over three and plot the next.

A jet travels 470 miles in 2 hours. At this rate, how far could the jet fly in 11 hours?

Answers

Answer:

The jet will cover 2585 miles in 11 hours.

Step-by-step explanation:

Given that:

Distance travelled by jet in 2 hours = 470 miles

Speed of jet = [tex]\frac{Distance}{Time}[/tex]

Speed of jet = 470/2

Speed of jet = 235 miles per hour

Time = 11 hours

Distance travelled in 11 hours = Speed * Time

Distance = 235 * 11

Distance = 2585 miles

Hence,

The jet will cover 2585 miles in 11 hours.

Zone II

Step-by-step explanation:

k ∈ A ∩ B means k is an element of both A and B.

zone II is in between zone I and zone III which is both.

The most specific location of k on the Venn Diagram is II.

What is Venn Diagram?

Venn diagram is a diagram denoting two or more sets which is drawn using circles inside a rectangle where the part where the two circle meet denotes the intersection of two sets.

Given is a Venn Diagram.

U represents the Universal set.

There are 2 sets, set A and set B, which are represented by 2 circles.

I represents the location of elements which are in A alone.

II represents the location of elements which are in B alone.

If an element belongs to A ∩ B, then the element contains both in A and B.

This is the location marked as II.

Hence the location of k will be in II.

How many cubic meters of water are required to fill a rectangular swimming pool 15m long and 10 m wide which is 2m deep throughout.How many liters is that?

Answers

Answer:

300,000 liters

Step-by-step explanation:

Let us have the measurements in cm

100 cm = 1 m

so the measurements are multiplied by 100

we have this as;

1500 by 1000 by 200

The volume is the product of the 3

This is :

1500 * 1000 * 200 = 300,000,000 cm^3

Mathematically, 1 liter = 1000 cm^3

300,000,000 cm^3 will be ;

300,000,000/1000 = 300,000 liters

which graph represents y=3x+2

Answers

Step-by-step explanation:

The general form of a straight line is y = mx + c, where m is the line's slope and c is the y-intercept.

For y = 3x + 2, the slope is positive 3 and the y-intercept is 2. The line should rise up and pass through the point (0, 2).

We are between Options B and C.

In Graph B, the line raises by 4 units for every 2 units across. Hence its slope is 4/2 = 2.

In Graph C, the line raises by 3 units for every 1 unit across. Hence its slope is 3/1 = 3.

Since we want 3 as the slope,

The answer is Option C.

The graph C represents y=3x+2

Solve 3-4/7 with steps pls

Answers

Since there are multiple steps, we would use PEMDAS. Since dividing comes before subtracting, we would divide -4/7 first.
-4/7= −0.571428571428571
Since it’s a really big decimal, we’re going to round it to the nearest hundredth. That would get you -0.57
Next we would do 3-0.57
3-0.57= 2.43

So your answer would be 2.43
