<u><em>Answer:</em></u>

-23.4 at 9:00 a.m.

<u><em>Step-by-step explanation:</em></u>

Make a ratio with the given numbers: -13, 5.

I believe the "common number" for the ratio of 1 a.m. would be:

2.6<u> : </u>1 times 9 = 23.4<u> </u><u>:</u><u> </u>9

A study of the use of social media asked a sample of 488 American adults under the age of 40 and a sample of 421 American adults
mr_godi [17]

Answer:

The correct option is (c).

Step-by-step explanation:

The assumptions of a two-sample <em>t</em>-test are:

  • Independent samples
  • Normality
  • Equal variances

It is provided that the sample of selected for American adults under the age of 40 is of size, <em>n</em>₁ = 488 and the sample of selected for American adults aged 40 or over is of size, <em>n</em>₂ = 421.

As the sample size is quite large the according to the Central limit theorem the sampling distribution of the sample mean would follow a Normal distribution.

And even if the sample was selected by dialing of various telephone numbers, the sample is not biased since the size of the sample is too large.

So, the sample can be considered as a simple random sample.

Thus, the conditions for two-sample t inference are satisfied.

The correct option is (c).

Compare the functions shown below:<br><br> Which function has the greatest maximum y-value?
solmaris [256]
Answer: It's a tie between f(x) and h(x). Both have the same max of y = 3

The highest point shown on the graph of f(x) is at (x,y) = (pi,3). The y value here is y = 3.

For h(x), the max occurs when cosine is at its largest: when cos(x) = 1. 
So,
h(x) = 2*cos(x)+1
turns into
h(x) = 2*1+1
h(x) = 2+1
h(x) = 3
showing that h(x) maxes out at y = 3 as well

--------------------------------

Note: g(x) has all of its y values smaller than 0, so there's no way it can have a max y value larger than y = 3. See the attached image to see what this graph would look like if you plotted the 7 points. A parabola seems to form. Note how point D = (-3, -2) is the highest point for g(x). So the max for g(x) is y = -2

romanna [79]

Answer:

78

Step-by-step explanation:

for the right side we can just do 14*2 since there are two people per seat and 14 rows

14 *2 is 28

for the left side we just do 14*3 since there are three people per seat and 14 rows

14*3 is 42

Then we have to add the 8 students that can fit in the very back seat

42 + 28 + 8

28 + 8 is 36

42 + 36 = 78
