PLS HURRY
Aneli [31]

Given:

The table of values.

Hours (h)        Dollars (d)

     1                       42

     2                      84

     3                     126

     4                     168

     5                       ?

To find:

The correct statements about the table.

Solution:

From the given table it is clear that,

1\times 42=42

2\times 42=84

3\times 42=126

4\times 42=168

This pattern can be defined as

h\times 42=d

Multiply h by 42 to get d. So, option A is correct.

Using this pattern, we get

5\times 42=210

The missing value in the last row is 210. So, option D is correct.

From the given table it is clear that the rate of change is $42 per hour because dollar is increasing by 42 in every hour.

A real-world situation that is represented in the table is “Richard is a video game designer and earns $42 per hour.”

Therefore, the option E is correct.

Evolutionary theories often emphasize that humans have adapted to their physical environment. One such theory hypothesizes that
timama [110]

Answer:

Step-by-step explanation:

Given that evolution theory hypothesizes that people should spontaneously follow a​ 24-hour cycle of sleeping and wakingdash–even if they are not exposed to the usual pattern of sunlight.

Sample size n = 8

df = 8- 1=7

Since population std deviation is not known, and sample size is small we can use only t test

H-0: x bar = 24\\H_a: x bar \neq 24

(two tailed test at 5% level of significance)

sd 3.142857143

 

se 1.111167799

Test statistic = Mean diff/se = 1.595

p = 0.1546

since p >0.05, accept null hypothesis.

There is no evidence to prove that the steady cycle is different from 24 hours.
