kipiarov [429]

Answer:

Based on this report, you can conclude that a total of ___11__ individuals participated in the research study .

Step-by-step explanation:

Given that a research report describing the results from a repeated-measures study states:

The data show no significant difference between the two treatments, t(10) = 1.65, p > .05.

Since t(10) is given, we can conclude that degrees of freedo is 10

Hence sample size is 10+1 =11

Based on this report, you can conclude that a total of ___11__ individuals participated in the research study .

Amiraneli [1.4K]

Answer

$35

Step-by-step explanation:

3lbs is 15 so get the price of 1 lb by dividing 15 by 3 which is 5. then multiply 5 by how many lbs you want. in this case 5 time 7 is 35

A sector of a circle has a central angle to 10° and arc length 28 pi units what is the radius of the circle

Dennis_Churaev [7]

Answer:

Radius = 504units

Step-by-step explanation:

Angle = 10°

Length of arc = 28π units

L = ∅/360 × 2πr

28π = 10/360 × 2πr

28π = 1/36 × 2πr

2πr = 28π × 36

π cancelled off.......

2r = 28 × 36

r = (28 × 36)/2

r = 28 × 18

r = 504units

Note that WXYZ has vertices W(-1, 2), X(-5, 7), y(-1, -2), and Z (3, -7).

svp [43]

a. Slope of WZ = -2.25; Slope of WX = 5

b. WZ = √97; WX = √41

c. WXYZ is not a <em>rectangle, rhombus, nor a square</em>. We can conclude that: <em>D. WXYZ is none of these</em>.

<h3>Slope of a Segment</h3>

Slope = change in y/change in x

Given:

W(-1, 2), X(-5, 7), Y(-1, -2), and Z (3, -7)

a. Slope of WZ and slope of WX:

Slope of WZ = (-7 - 2)/(3 -(-1)) = -2.25

Slope of WX = (7 - 2)/(-1 -(-1)) = 5

b. Use distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$ , to find WZ and WX:

$WZ = \sqrt{(3 - (-1))^2 + (-7 - 2)^2}\\\\\mathbf{WZ = \sqrt{97} }$

$WX = \sqrt{(-5 -(-1))^2 + (7 - 2)^2}\\\\\mathbf{WX = \sqrt{41} }$

c. The quadrilateral WXYZ have adjacent sides that are not perpendicular to each other and have different slopes and different lengths, so therefore, WXYZ is not a rectangle, rhombus, nor a square. We can conclude that: <em>D. WXYZ is none of these</em>.
