Hello from MrBillDoesMath!

Answer:

A number is divisible by 2 if the number is even (e.g. 2. 52, 96, etc.)

Odd numbers, such as 3, 17, 27 are NOT divisible by two.

The sum of the speeds two trains is 717.6 miles per hour. If the speed of the first train is 6.4 mph faster than that of the sec

damaskus [11]

Train 1 = x + 6.4

Train 2 = x

(x) + (x + 6.4) = 717.6

2x + 6.4 = 717.6

2x = 711.2

x = 355.6

Train 1 = 355.6 + 6.4 = 362 mph

Train 2 = 355.6 mph

Hope this helps!! :)

1... -14 6(3k + 5)----------------------------------------------------------------------------------------------

Lelu [443]

Answer:

-5/3, or in decimal form, -1.666.

Step-by-step explanation:

a. -146 (3k+5) --- distribute the -146 to "3k" and "+5."

b. -438k - 730 = 0 --- get the variable k to one side of the equation.

c. -438k=730 --- divide by -438 on both sides.

d. the answer you get is 730/-438, which, in simpler terms, is -5/3, or -1.666.

Answer: 1.460

Step-by-step explanation:

Given : Researchers report that on average freshman who live on campus gain 15 pounds during their first year in college.

Let $\mu$ represents the population mean .

Then, the set of hypothesis will be:-

$H_0: \mu=15$

$H_a:\mu\neq15$

We assume that this is normal distribution.

Sample size : n = 10, which is a small sample (n<30) ,s o we use t-test.

Sample mean : $\overliene{x}=16.2\ lbs$

Standard deviation : $\sigma=2.6$

The test statistic for population mean for small sample is given by :-

$t=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

$t=\dfrac{16.2-15}{\dfrac{2.6}{\sqrt{10}}}=1.45951276623\approx1.460$

Hence , the value of test statistic = 1.460
