If you wanted to find 8 percent of 90 you would just multiply 90 by .08 and you would get your answer which would be 7.2

Bas_tet [7]

Answer:

2x+12

Step-by-step explanation:

2x+3(x−2)−3(x−6)

Distribute:

=2x+(3)(x)+(3)(−2)+(−3)(x)+(−3)(−6)

=2x+3x+−6+−3x+18

Combine Like Terms:

=2x+3x+−6+−3x+18

=(2x+3x+−3x)+(−6+18)

=2x+12

Answer:

=2x+12

Alisiya [41]

Answer:

The 25th percentile is 248.

The 70th percentile is 700.

Step-by-step explanation:

The pth percentile is a data value such that at least p% of the data-set is less-than or equal to this data value and at least (100-p)% of the data-set are more-than or equal to this data value.

Arrange the data set in ascending order as follows:

S = {75 , 157 , 224 , 248 , 271 , 381 , 472 , 495 , 586 , 676 , 700 , 723 , 743 , 767 , 1250}

The formula to compute the position of the pth percentile is:

$p^{th} \text{Percentile}=\frac{(n+1)\cdot p}{100}$

Compute the 25th percentile as follows:

$25^{th} \text{Percentile}=\frac{(15+1)\cdot 25}{100}=4^{th}obs.$

The 4th observation from the arranged data set is 248 .

Thus, the 25th percentile is 248.

Compute the 70th percentile as follows:

$70^{th} \text{Percentile}=\frac{(15+1)\cdot 70}{100}\approx 11^{th}obs.$

The 11th observation from the arranged data set is 700.

Thus, the 70th percentile is 700.

Please Help!! This is Geometry.

dolphi86 [110]

If M is the midpoint of PQ, then PM and MQ are equal.

As PM and MQ are given , equal them to each other to solve for x.

7x+8=5x+20

Subtract 5x on both sides to get 2x+8=20

Subtract 8 on both sides to get 2x=12

divide by 2 on both sides to get x=6

Use the value of x=6 and plug it into the equations for PM and MQ to find their value.

PM=7x+8

=7(6) 8 =42 + 8 = 50

(you can already tell MQ is also 50 as PM and MQ are equal, but we still solve for MQ just for the fun of it)

MQ=5x + 20

=5(6) +20=30+20=50

PM=50

MQ=50

PQ= PM + MQ= 50 + 50 = 100

Have a great night.

What happens to the equation when y = x becomes y = -x?

notka56 [123]

Well -x is the opposite of x

so i think that it makes the lines perpendicular

Solve for x.4(2x + 3) = 3x + 3 + 2x

ElenaW [278]

Answer:

The value of x is -3.

Explanation:

Given the equation:

$4\mleft(2x+3\mright)=3x+3+2x$

Step 1: Distribute 4 in the left-hand side.

$\begin{gathered} 4\mleft(2x)+4(3\mright)=3x+3+2x \\ 8x+12=3x+2x+3 \\ 8x+12=5x+3 \end{gathered}$

Step 2: Collect like terms.

$\begin{gathered} 8x-5x=3-12 \\ 3x=-9 \end{gathered}$

Step 3: Divide both sides by 3.

$\begin{gathered} \frac{3x}{3}=-\frac{9}{3} \\ x=-3 \end{gathered}$

The value of x is -3.
