Answer:

85

Step-by-step explanation:

The discount is original price times the percent off

The sale price is the original price minus the discount

original price - original price * 20 % = 68

Factor out the original price and change the percent to a decimal

original price ( 1 - .20) = 68

original price ( .80) = 68

Divide each side by .80

original price = 68/.80

original price = 85

Can ratios have decimals in them or do all the numbers have to be integers? E.g. is 7.8:1.3:6.5 a valid ratio?
nadezda [96]
What you have is a valid ratio in theory, but it might be easier to understand if it were simplified to integers:

78:13:65

It also depends on what your teacher is asking of you.

Name the intersection of plane ACG and plane BCG
Ira Lisetskai [31]
<u><em>Answer:</em></u>
CG

<u><em>Explanation:</em></u>
A plane is defined using three points.
The intersection between two planes is a line

<u>Now, we are given the planes:</u>
<span>ACG and BCG
</span>
By observing the names of the two planes, we can note that the two points C and G are common.
This means that line CG is present in both planes which means that the two planes intersect forming this line.

Hope this helps :)

A clinical psychologist wants to test whether experiencing childhood trauma affects one's self-efficacy in adulthood. He randoml
Verdich [7]

Answer:

Step-by-step explanation:

We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean

For the null hypothesis,

µ = 152.5

For the alternative hypothesis,

µ ≠ 152.5

This is a two tailed test.

Since no population standard deviation is given, the distribution is a student's t.

Since n = 231

Degrees of freedom, df = n - 1 = 231 - 1 = 230

t = (x - µ)/(s/√n)

Where

x = sample mean = 148.9

µ = population mean = 152.5

s = samples standard deviation = 27.4

t = (148.9 - 152.5)/(27.4/√231) = - 2

We would determine the p value using the t test calculator. It becomes

p = 0.047

Since alpha, 0.05 > thanthere sufficient evidence to conclude that the self-efficacy of adults who have experienced childhood trauma differs from that in the general population of individuals the p value, 0.047, then we would reject the null hypothesis. Therefore, At a 5% level of significance, there is sufficient evidence to conclude that the self-efficacy of adults who have experienced childhood trauma differs from that in the general population of individuals
