Answer: 32

Step-by-step explanation: The median is the middle number in the data set when the data set is written from least to greatest.

So let's write our data set from least to greatest.

18, 24, 32, 48, 90

So the median is the middle number or 32.

Answer:

The median is 32.

Step-by-step explanation: To find the median:

Step 1: Put all the numbers in order from least to greatest.

Step 2: Cross out the other numbers until you get to the middle.

Step 3: Once you cross out all the numbers evenly, the only number remaining is 32.

Answer:

-7 - 3a = 1 – 4a  

Step one: Add 4a to -3a  

-7 + a = 1  

Step two: Add 7 to 1  

A = 8  

You're done! A=8 for this problem!  

Hopefully this helps! Feel free to mark brainliest!  

Answer:

[tex]a =8[/tex]

Step-by-step explanation:

[tex]-7 - 3a = 1 - 4a[/tex]

add [tex]3a[/tex] to both sides

[tex]-7 - 3a + 3a = 1 -4a + 3a \\-7 = 1 -a[/tex]

add [tex]-1[/tex] to both sides

[tex]-7 - 1 = 1 - a -1\\-8 = -a[/tex]

multiply both sides by [tex]-1[/tex]

[tex]-8 * (-1) = -a * (-1) \\8 = a[/tex]

It does not matter which of the two "slope" formulas you use, nor does it matter which point you pick to be your "first" and which you pick to be your "second". The only thing that matters is that you subtract your x-values in the same order as you had subtracted your y-values.

Step-by-step explanation:

The problem bothers on the dimension of a scaled drawing/prototype

The indications on the blueprint actually represent the scale

 that is 1 inch: 3.5 feet

Given that a wall is 6 inches on the blueprint, now, in reality, the  actual    

 length will be 3.5*6= 21 feet

Usually, the scale is given as a ratio. A drawing, which has been reduced or enlarged or a drawing whose dimensions have been changed to a particular size other than its previous or initial size is a scaled drawing.

Answer: LCM=672; HCF=12

Step-by-step explanation:

LCM=Least Common Multiple

HCF=Highest Common Factor

Factor of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84

Factor of 96: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96

From the list we can see, the highest common factor between 84 and 96 is 12.

The easiest way to find least common multiple is to time the numbers together and then divide it by their highest common factor.

84×96÷12=672

Answer:

Step-by-step explanation:

Let the probability of people being white be P ( W ) and being diseased

be P ( D )

Given

P ( W ) = .72 ,  P ( D ) = .3

P ( W∩D ) = .2

a )

P ( [tex]W^c[/tex] ∩ [tex]D^c[/tex] ) = P[tex]( WUD)^c[/tex] = 1 - P ( W U D )

= 1 - [ P( W ) + P ( D ) - P ( W ∩ D ) ]

= 1 - ( .72 + .3 - .2 ) = .18

b )

P ( D / W ) = P ( W∩D ) / P(W) = .2 / .72 = .27778

c )

No , because

P ( W∩D ) = .2

p ( W)  x P ( D ) = .72  x .3 = .216

so P ( W∩D )  is not equal to P ( W)  x P ( D )

d )

We shall apply binomial distribution

chance = 10C₂ x  .3² ( 1 - . 3 )⁸

Answer:

This is pretty simple, it tells you that two tickets are worth $18, to figure out how much one would cost you just divide 18/2 and that would equal $9. So Your answer would be Each ticket sold yields $9 of profit.

Here, Let, Number of Ticket = x

Sold profit = y

Then, relation would be: 18/2 = 9

y = 9x

In short, Your Answer would be Option B) "Each ticket sold yields $9 of profit"

Hope this helps!

Answer:

its B: Each ticket sold yields $9 of profit.

[tex]Unit\ Charge = -6\ units[/tex]

Step-by-step explanation:

Question is incomplete; However, the missing part of the question will most likely be to calculate the charges on each particle.

If that is the case;

[tex]Tota\l Charges = -42\ units[/tex]

We'll get the unit charge when we divide by 7.

This is so because, they all have the same charge.

[tex]Unit\ Charge = -42\ units/7[/tex]

[tex]Unit\ Charge = -6\ units[/tex]

Hence;

the unit charge is -6 units

Answer:

the unit charge is -6 units

Answer:

The constant of proportionality is the number of kilograms that will stretch the spring by 1 inch. When y = 1, x = 1/3, so the constant of proportionality in kilograms per inch is 1/3.

Answer:At least around 30%

Step-by-step explanation:

So when looking at the question there is an 800 and 760.

So the question is basically asking you to subtract your numbers. so do "800-760" And u should get 30 :).

Answer:

95

Step-by-step explanation:

800 (the original price) - 100 perecent

760 (the decreased price) - x perecent

We multiply diganol and divided the only number left, so:

760 times 100 divided by 800.

You get 95!

Answer:

1 and 3

Step-by-step explanation:

because 5 and 3 have the same value and since 5 and 1 add up to 90 degrees, 3 and 1 must also add up to 90 degree

Angles ∠1 and ∠3 are complementary but not adjacent.

Complementary angles are two angles that add up to 90 degrees.

Adjacent angles are two angles that share a common vertex and a common side.

In the image, angles ∠1 and ∠3 share a common vertex, but they do not share a common side. They are also not adjacent to each other, as there is an angle in between them (angle ∠4).

The measure of angle ∠1 is 48 degrees. The measure of angle ∠3 is 42 degrees. Therefore, angles ∠1 and ∠3 add up to 90 degrees, making them complementary angles.

Step-by-step explanation:

Hey there! I'm happy to help!

We have 8 bags of dog food and each costs $25.19

8(25.19)=201.52

And we have 11 leashes each costing $4.65.

11(4.65)=51.15

We add these totals up.

201.52+51.15=252.67

We subtract this from 300 to see how much is left.

300-252.67=47.33

Step-by-step explanation:

Answer:

y = -(4/5)x + 7

Step-by-step explanation:

recall that the point-slope form of a linear equation is given as

y - y₁ = m (x - x₁)

in our case, we are given

slope, m = -4/5

and a point (x₁, y₁) = (5,3)

hence we simply substitute these values into the equation

y - y₁ = m (x - x₁)

y - 3 = -(4/5) (x - 5)    (we will simplify this to convert to slope-intercept form)

y - 3 = -(4/5) (x) - (-4/5)(5)

y - 3 = -(4/5)x +4   (add 3 to both sides)

y = -(4/5)x +4  +3

y = -(4/5)x + 7
