In this question i can only help with the 2nd part!

Part B:

Mean:

65 + 67 + 66 + 70 + 72 + 68 + 69 / 7

477 / 7

= 68.142 = 68

Median:

65, 66, 67, 68, 69, 70, 72

Median = 68

Mode:

There is no mode

Range:

65, 66, 67, 68, 69, 70, 72

72 - 65 = 7

A train travels 25 miles in 20 minutes. What is the train speed in miles per hour?

kenny6666 [7]

60 min = 1 hour

1st we need to know how many times 20 goes in 60 so we will divide.

60 ÷ 20 = 3

Now we will multiply to find the trains speed in miles per hour.

3 × 25 = 75

SO, the train travels 75 miles per hour.

Hope I helped ya!!

−3(2+4k)+7(2k−1) eqivalent expression

Alex17521 [72]

Answer:

$\large\boxed{-3(2+4k)+7(2k-1)=2k-13}$

Step-by-step explanation:

$-3(2+4k)+7(2k-1)\qquad\text{use the distributive property}\ a(b+c)=ab+ac\\\\=(-3)(2)+(-3)(4k)+(7)(2k)+(7)(-1)\\\\=-6-12k+14k-7\qquad\text{combine like terms}\\\\=(-12k+14k)+(-6-7)\\\\=2k-13$
