Let X describes the sales
350.25+0.12x=800.5
Now solve for x
0.12x=800.5-350.25
0.12x=450.25
X=450.25÷0.12
X=3,752.08
the sales necessary for the salesperson to earn at least $800.50 in one week is 3,752.08
Answer:
The LCD in 1/30 + 1/24 is <u>90</u>.
Answer:
![d = \frac{78.24 -66.25}{\sqrt{\frac{7^2 +7^2}{2}}}= 1.713](https://tex.z-dn.net/?f=%20d%20%3D%20%5Cfrac%7B78.24%20-66.25%7D%7B%5Csqrt%7B%5Cfrac%7B7%5E2%20%2B7%5E2%7D%7B2%7D%7D%7D%3D%201.713)
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:
![d = \frac{\bar X_1 -\bar X_2}{\sqrt{\frac{s^2_1 +s^2_2}{2}}}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Cfrac%7B%5Cbar%20X_1%20-%5Cbar%20X_2%7D%7B%5Csqrt%7B%5Cfrac%7Bs%5E2_1%20%2Bs%5E2_2%7D%7B2%7D%7D%7D)
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:
![d = \frac{78.24 -66.25}{\sqrt{\frac{7^2 +7^2}{2}}}= 1.713](https://tex.z-dn.net/?f=%20d%20%3D%20%5Cfrac%7B78.24%20-66.25%7D%7B%5Csqrt%7B%5Cfrac%7B7%5E2%20%2B7%5E2%7D%7B2%7D%7D%7D%3D%201.713)
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.
Answer:
a
Step-by-step explanation:
Answer:
A. at least two congruent sides
Step-by-step explanation:
Since, we know that,
'An isosceles triangle is a triangle having two sides of equal length or at least two sides of equal length (special case is equilateral triangle)'.
Thus, from the options, we see that,
Options B, C and D are not correct.
<em>Since, congruent sides means that the lengths of the sides are equal.</em>
Thus, we get that,
'An isosceles triangle has at least two congruent sides'.
Hence, option A is correct.
