The table below shows 10 data values:

1 answer:

7 0

It would be d , because the lowest number which is your (min) is 72 the highest number which is your (max) is 93 . Your median would be 85 because you would add 84 & 86 and in result you would get 170 then you would divide by 2 and get 85 . Your Q1 would be 76 and your Q3 would be 91 , there is 10 numbers in total separate them (72,74,76,83,84) and (86,89,91,92,93) then find the middle number in each

Hope this helps !

Step-by-step explanation:

Step 1: Define

Identify

x + (3x - 4) = 5 - (-7 - 3x)

Step 2: Solve for x

[Distributive Property] Distribute negative: x + 3x - 4 = 5 + 7 + 3x
[Addition] Combine like terms: 4x - 4 = 12 + 3x
[Subtraction Property of Equality] Subtract 3x on both sides: x - 4 = 12
[Addition Property of Equality] Add 4 on both sides: x = 16

Which of these conditions does not guarantee that a quadrilateral is a parallelogram? A. Both pairs of opposite angles are congr

frutty [35]

Answer:

Option D is the correct condition that gives 'One pair of opposite sides is congruent'.

Step-by-step explanation:

We have to select the condition from the four options that do not guarantee that a quadrilateral is a parallelogram.

Option D is the correct condition that gives 'One pair of opposite sides is congruent'.

This is because if one pair of opposite sides of the quadrilateral are congruent, then they may not be parallel and hence the quadrilateral may not be a parallelogram. (Answer)

Any help will do! Thank you!

leonid [27]

Let's take this problem step-by-step:

First let's set up the equation for the cost for one week of renting the car

agency charges $230 per week

$charge = 230$

agency charges $0.25 per mile (lets set the number of miles as 'x')

$charge = 230 + 0.25x$

The total cost was 415, therefore:

$415 =230 + 0.25x\\185 = 0.25x\\x = 740$

Therefore, you traveled 740 miles

Answer: 740 miles

Hope that helps!

Rearrange the equation so a is the independent variable 3a-7=-4b+1

ycow [4]

Answer:

$b=\frac{-3}{4}a+2$

Step-by-step explanation:

a is the independent means a doesn't change its value when b change. So we will make b depends on a instead.

$3a-7=-4b+1\\4b=-3a+7+1\\b=\frac{-3}{4}a+2$

As of January 2005, the U.S. Senate Committee on Indian Affairs had 14 members. Assuming party affiliation was not a factor in s

Nastasia [14]

Answer: $4.42\times10^{16}$

Step-by-step explanation:

Given : The total number of U.S. senators = 100

The number of members in U.S. Senate Committee = 14

Since Assuming party affiliation was not a factor in selection , we use combinations.

Formula : $^nC_r=\dfrac{n!}{r!(n-r)!}$

Then , the number of different committees were possible from the 100 U.S. senators :

$^{100}C_{14}=\dfrac{100!}{14!(100-14)!}\\\\=\dfrac{100\times99\times.....87\times86!}{14!86!}\\\\=\dfrac{100\times99\times.....87}{14\times13\times12.....\times1}\\\\\approx4.42\times10^{16}$

Hence, the number of different committees were possible from the 100 U.S. senators is $4.42\times10^{16}$ .
