What is the distance between point A and point B? - 1

Answers

Answer 1
Answer: distance formula is like pythagoren ahtoerem
D=\sqrt{(7-2)^(2)+(5-8)^(2)}
the distance between oints (x1,y1) and (x2,y2) is
D=\sqrt{(x1-x2)^(2)+(y1-y2)^(2)}
A=(-3,-1) and (5,2)
D=\sqrt{(-3-5)^(2)+(-1-2)^(2)}
D=\sqrt{(-8)^(2)+(-3)^(2)}
D=√(64+9)
D=√(73)
aprox
D=8.54
round
D=8.5 units

What is the median for the numbers 3.60, 3.80, 5.44, 5.52, 5.72, 7.22?I know it's between 5.44 and 5.52

Answers

okay so first of all we need to know the definition of our median first*
median: Given any group of numbers we put the numbers in order from least to greatest then find the number that's right in the middle. 
Here ill show you how we do it:)
3.60, 3.80, 5.44, 5.52, 5.72, 7.22?
its already in order for us:)
but when we find the middle number it turns out that we have two middle numbers:/
simple:) all we do is take the two numbers add them together and divide by two
since our middle numbers are 5.44 and 5.52 we are going to use these:)
first add!
5.44 + 5.52 = 10.96 
now divide that by 2 
10.96 ÷ 2 = 5.48
so our median for this set of numbers is 
5.48!
hope this helps;)
The answer is 5.48 because the middle numbers are 5.44 and 5.52 so what you do is find the mean or average of the two numbers by adding them together then dividing them by two, so: (5.44 + 5.52) / 2 = 5.48

Are all equilateral triangle acute triangles?

Answers

yes sir, in equilateral triangles, all angles and sides have to be congruent
therefore, each angle has to be 60 degrees (180/3)
thus, they're all acute
Yes, all equilateral triangles have to be acute because to have equal sides you need equal angles.

Directions: Select the correct answer from each drop-down menu.Sandy's orchard has only apple trees and pear trees and she is wanting to add some avocado trees. Currently, there are 4 apple trees for every 3 pear trees. She is wanting to plant enough avocado trees so that she has 2 avocado trees for every 5 pear trees in the orchard. Sandy is planting 18 avocado trees, making the ratio of avocado trees to apple trees be to .

Answers

First lets get the ratio for the avocado and pear trees and work from there
We know there are 5 pear trees for every 2 avocado trees or 5:2

Since we know the total Avocado trees is 18 we can find out how much to multiply the ratio by dividing the total number of trees(18) by the Avocado portion of the ratio (2) 18/2 = 9. 

This means to get the total number of pear trees we need to also multiply the pear side of the ratio (5) by 9.  5*9 = 45 pear trees

Now that we know the pear trees we do the same thing with the apple and pear trees to figure out the total apple trees.  The ratio of apple to pear trees is 4:3.

Since we know the total number of pear trees is 45 we divide that by the pear side of the ratio (3) to get our multiplier.  45/3=15. 

We then multiply our apple side of the ratio (4) by our multiplier (15) to get our total number of apple trees.  4*15=60

Now we know that we have 60 apple trees and 18 avocado trees or 60:18 which reduced is 10:3  apple trees:avocado trees

Answers

The MAD of set 1 is 10.5 less than the MAD of set 2.

What is MAD?

MAD is mean absolute deviation which is calculated by

MAD = ∑₁ⁿ(|x - μ|)/n

Given data of set 1 : 5,10,7,2

and set 2: 5,10,7,42

MAD of set 1 = MAD(1) =  ∑₁ⁿ(|x - μ|)/n

where μ is mean of set 1 and x are the entries of set and n is no. of entries,

μ =( 5+10+7+2)/4 =24/4 =6

now reduce the values of set 1 from mean

|x - μ| of set = 1,4,1,4

MAD(1) = ∑₁ⁿ(|x - μ|)/n = (1+4+1+4)/4 =10/4

MAD(1) = 2.5

MAD of set 2 = MAD(2) =  ∑₁ⁿ(|x - μ|)/n

calculate mean for set 2

μ =( 5+10+7+42)/4 =64/4 = 16

now reduce the values of set 2 from mean

|x - μ| of set = 11,6,9,26

MAD(2) = ∑₁ⁿ(|x - μ|)/n =(11+6+9+26 )/4 =52/4

MAD(2) = 13

MAD(2) - MAD(1)  = 13-2.5 = 10.5

Hence the set 1 is 10.5 less then set 2

Answer:

the answer is C

Step-by-step explanation:

if you do 5+10+7+2 you get 24 divide by 4 you get 6 mean is 6 for set 1

Set 2 if you do 5+10+7+42 you get 64 divide by 4 and you get 16 16-10.5 you get so 5.5 set is less than set 2 there ya go dude

A right prism has a base in the shape of an octagon. The side length of the octagon is 4 inches. The length of theapothem is 4.83 inches. The height of the prism is 12 inches. What is the volume of the prism? Round your answer
to the nearest whole number
cubic inches

Answers

The volume of the prism with octagon base is 927.058 in³

How to calculate volume?

Volume is the amount of space occupied by a three dimensional shape or object.

The area of the octagon = 2(1 + √2) * side² = 2(1 + √2) * 4² = 77.25 in²

The volume of the prism = area of base * height = 77.25 in² * 12 in = 927.058 in³

The volume of the prism with octagon base is 927.058 in³
