Answer:

4x+15 Is the answer

Step-by-step explanation:

4(6−2x)−3(3−4x)

Distribute:

=(4)(6)+(4)(−2x)+(−3)(3)+(−3)(−4x)

=24+−8x+−9+12x

Combine Like Terms:

=24+−8x+−9+12x

=(−8x+12x)+(24+−9)

=4x+15

Hey there!

“ Simplify 4(6 - 2x) - 3(3 - 4x)”

FIRST: you have to DISTRIBUTE

4(6) + 4(–2x) + (–3)(3) + (–3)(–4x)

4(6) = 24

4(–2x) = –8x

–3(3) = –9

–3(–4) = 12x

NEW EQUATION: 24 – 8x – 9 + 12x

SECOND: COMBINE your LIKE TERMS

(24 – 9) + (–8x + 12)

24 – 9 = 15

–8x + 12 = 4x

OR........ (MAINLY this one )

(–8x + 12) + (24 - 9)

(–8x + 12) = 4x ⬅️ FRONT NUMBER

24 – 9 = 15 ⬅️ BACK NUMBER

ANSWER: 4x + 15 ☑️

Good luck on your assignment and enjoy your day!

Find the area of circle o if DCBO is a rectangle and DB measure 10 units
Dmitrij [34]

Answer:

100\pi

Step-by-step explanation:

Step 1: Identity the radius.

Since O is the center of the circle, and C and E lie on the circumference, OC and OE are the radii of the circle and thus,

OC=OE.

Step 2: Consider the rectangle.

All diagonals in a rectangle are congruent so this means

DB= OC ( OC is also a diagonal).

Thus, OC= 10 units.

Step 3: Analyze

So this means OE is also 10 units as well.

Since we know the length of the radius, Use the area of circle,

\pi {r}^{2}

\pi( {10}^{2} ) = 100\pi

So the area of a circle is 100 pi.

Data were collected from a typing class with 45 students. The class had an average of 56 words per minute (WPM) with a standard
STALIN [3.7K]

Answer:

Standard deviation gets smaller

Step-by-step explanation:

No. of students = 45

The class had an average of 56 words per minute (WPM) with a standard deviation of 7 WPM.

Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}\\56=\frac{Sum}{45}\\56 \times 45=Sum\\2520=Sum

The teacher realized that the data from one student who typed 55 WPM was not entered.

So, new sum = 2520+55

New sum =2575

So, new mean =\frac{2575}{45}

New mean =57.22

Standard deviation is the measure of distance between observation and mean

So, if number gets closer to mean , Standard deviation gets smaller . if the numbers get bigger , Standard deviation gets bigger.

Since 55 is closer to 57.22

So, Standard deviation gets smaller
