Answer:

A , B, D

Step-by-step explanation:

Use the Venn diagram to calculate conditional probabilities.

Circles D, E, and F overlap. Circle D contains 13, circle E contains 4, and circle F contains F. The overlap of D and E contains 6, the overlap of E and F contains 7, and the overlap of F and D contains 5. The overlap of all 3 circles contains 5. Number 3 is outside of the circles.

Which conditional probabilities are correct? Check all that apply.

A. P(D | F) = StartFraction 6 Over 34 EndFraction <-- correct

B. P(E | D) = StartFraction 7 Over 25 EndFraction <-- correct

P(D | E) = StartFraction 7 Over 25 EndFraction

D. P(F | E) = StartFraction 8 Over 18 EndFraction <-- correct

P(E | F) = StartFraction 13 Over 21 EndFraction

What is the slope??????

nikitadnepr [17]

Answer: The slope is 1/4.

Step-by-step explanation:

To find the slope, find two points on the line and find the difference in their y coordinates and divide it by the difference in their x coordinates .

(0,20) and (40,30)

Difference in y: 30 - 20 = 10

Difference in x: 40 - 0 = 40

Slope: 10/ 40 = 1/4

A repeated-measures study comparing two treatments with n = 4 participants produces md = 2 and ss = 75 for the difference scores

valentinak56 [21]

The estimated standard error for the sample mean difference is 2.5 .

According to the question

A repeated-measures study comparing two treatments

n = 4

MD(mean difference) = 2

SS (sum of square) = 75

Now,

error for the sample

Formula for standard error

$S^{2} = \frac{SS}{n-1}$

by substituting the value

$S^{2} = \frac{75}{4-1}$

$S^{2} = \frac{75}{3}$

S² = 25

S = 5 (s is never negative)

Standard error of the estimate for the sample mean difference

The standard error of the estimate is the estimation of the accuracy of any predictions.

The formula for standard error of the mean difference

standard error of the mean difference = $\frac{standard\\\ error}{\sqrt{n} }$

standard error of the mean difference = $\frac{5}{\sqrt{4} }$

standard error of the mean difference = 2.5

Hence, the estimated standard error for the sample mean difference is 2.5 .

Solve for x in the figure below

fredd [130]

Answer:

x = 35.4

Step-by-step explanation:

Sum of all interior angles in a triangle = 180°

Therefore:

(x + 2)° + (2x + 2)° + (2x - 1)° = 180°

x + 2 + 2x + 2 + 2x - 1 = 180

Collect like terms

x + 2x + 2x + 2 + 2 - 1 = 180

5x + 3 = 180

Subtract 3 from each side

5x + 3 - 3 = 180 - 3

5x = 177

Divide both sides by 5

5x/5 = 177/5

x = 35.4

is it always,sometimes, or never true that a scatter plot that shows a positive association suggest that the relationship is pro

quester [9]

When a scatter plot shows a positive association means that there is a linear correlation with a positive slope between the two variables. This correlation can be weaker or stronger (depending on the value of the correlation).
If there is a linear correlation between the two variables, the relation is then a direct proportionality (with slope positive or negative).

Hence, it is always true that <span>a scatter plot that shows a positive association suggests that the relationship is proportional.</span>
