Good evening ,
______
Answer:
(4c-d+0.2)² - 10c = 33
___________________
Step-by-step explanation:
(4c-d+0.2)^2-10c
c=3.1, d=4.6
(4(3.1) - 4.6 + 0.2)² - 10(3.1) = (12.4 - 4.6 + 0.2)² - 31 = (7.8 + 0.2)² -31 = 8² - 31 = 64-31 =33.

Answer:
b. Cubic
Exponential and logarithmic graphs are the similar, logarithmic graphs just reflect exponential graphs. Cubic root is like the one shown, just horizontal.
Answer:

For the interpretation we consider a value for d small is is between 0-0.2, medium if is between 0.2-0.8 and large if is higher than 0.8.
And on this case 1.713>0.8 so we have a large effect size
This value of d=1.713 are telling to us that the two groups differ by 1.713 standard deviation and we will have a significant difference between the two means.
Step-by-step explanation:
Previous concepts
The Effect size is a "quantitative measure of the magnitude of the experimenter effect. "
The Cohen's d effect size is given by the following formula:

Solution to the problem
And for this case we can assume:
the mean for females
the mean for males
represent the deviations for both groups
And if we replace we got:

<u>Answer</u>:
The female would pay $322.00 less for a policy of $25,000
<u>Step-by-step explanation:</u>
Since we have given that
Amount for policy = $25000
If she opt for 20 year life insurance at $2.90 per $1000.
so, her amount of premium becomes

=$72.50
If she opt for straight life insurance at $15.78 per $1000,
Then, her amount of premium becomes

= $394.50
Difference between them is given by
$394.50-$72.5 = $322.00
