Answer:

Each section below

Step-by-step explanation:

(a) Add all frequencies together = 200, then add 1 and divide by 2 = 100.5, lastly you need to add each frequency until you find the interval that contains the 100th and 101st height.

23+47 = 70

70+45 = 115 -> so the answer is 10<h<u><</u>13

(b) Step 1: find the midpoint of each interval (upper limit+lower limit then divide by 2)

(2+6)/2 = 4

(6+10)/2 = 8

(10+13)/2 = 11.5

(13+17)/2 = 15

(17+19)/2 = 18

(19+20)/2 = 19.5

Step 2: multiply the midpoint of each interval with it's frequency

4*23 = 92

8*47 = 376

11.5*45 = 517.5

15*38 = 570

18*32 = 576

19.5*15 = 292.5

Step 3: add all of the above and divide it by the total frequency

92+376+517.5+570+576+292.5 = 2424

2424/200 = 12.12 (this is your answer to part b)

Hope this helped :)

Find the value of x ?
enyata [817]

Answer:

Step-by-step explanation:

∠E = ∠G

∠D= ∠F because it’s a parallelogram ==> D=F=2x+12 and E=G=5x

5x+2x+12=180

7x=168

X=24

Solution 2:

2*5x+2*(2x+12)=360

10x+4x+24=360

14x=360-24=336

X=336/14

X=24

Choose the best answer that represents the property used to rewrite the expression.
Andre45 [30]

Answer:

The Quotient Property.

Step-by-step explanation:

Since all three logarithms have the same base (base-5), and you are subtracting 6 and 3, to solve this all you need to do is 6 / 3 because of the Quotient Property.

You aren't multiplying anything, so you wouldn't use the Product Property.

You are not messing around with powers, so you wouldn't use the Power Property.

And you aren't using addition or multiplication, so you wouldn't use the Commutative Property.

Hope this helps!

A rectangular garden has a walkway around it. The area of the garden is 6(6.5x + 2.5). The combined area of the garden and the w
Rasek [7]

According to the information given in the exercise, the following expression represents the area of the rectangular garden:

6\mleft(6.5x+2.5\mright)

And the following expression represents the combined area of the walkway around the rectangular garden and the area of the garden:

6.5\mleft(8x+6\mright)

You can identify that the word "combined" indicates that that expression was obtained by adding both areas.

Knowing the above, you can set up the following equation:

6(6.5x+2.5)+A=6.5(8x+6)

Where "A" is the area of the walkway around the rectangular garden.

Solving for "A", you get the following expression:

\begin{gathered} A=6.5(8x+6)-6(6.5x+2.5) \\ A=52x+39-39x-15 \\ A=13x+24 \end{gathered}

The answer is:

13x+24

Sonya has 140 beads. how many bags of 10 beads does she need so that she will have 200 beads in all
Vikentia [17]
If Sonya already has 140 beads, she needs 60 beads in order to have a total number of 200 beads. You have to find how many bags (that hold 10 beads) are needed to add up to 60.

140 + 10x = 200
10x = 60
x = 6

Sonya needs 6 bags
