Researchers would like to test if the mean bone mineral density is different for the three different groups. Conduct an ANOVA te
laiz [17]

Answer:

<em>H</em>₀: <em>μ₁ = μ₂= μ₃</em>

<em>Hₐ: </em>At least one of the means is different.

Step-by-step explanation:

Analysis of variance or ANOVA test is used to determine whether the means of different groups are similar or not.

The hypothesis of an ANOVA test for <em>n</em> homogeneous groups is:

H_{0}: \mu_{1}= \mu_{2}= \mu_{3}...= \mu_{n}\\H_{a}: At\ least\ one\ of\ the\ means\ is\ different

In this case the researcher is testing whether the mean bone mineral density is different for the three different groups.

The hypothesis for this test can be defined as follows:

<em>H</em>₀: The mean bone mineral density is not different for the three different groups, i.e. <em>μ₁ = μ₂= μ₃</em>

<em>Hₐ: </em>The mean bone mineral density is different for the three different groups, i.e. at least one of the means is different.

A coordinate plane with a line passing through (0, negative 3), (2, 0), and (4, 3). Which equation represents the graphed functi
Talja [164]

Answer:

y=\frac{3}{2}x-3

Step-by-step explanation:

we have the points

(0,-3),(2,0) and (4,3)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we take

(0,-3),(2,0)

substitute the values in the formula

m=\frac{0+3}{2-0}

m=\frac{3}{2}

step 2

Find the equation of the line in slope intercept form

y=mx+b

we have

m=\frac{3}{2}

b=-3 -----> the point (0,-3) is the y-intercept

substitute

y=\frac{3}{2}x-3

The graph in the attached figure

Please help I really need to pass this exam<br> If line GF is a midsegment of triangle CDE, find CD.
olga55 [171]
CF = FG = GC because it is equilateral triangle

So
3x + 0.8 = 2x + 3

3x–2x = 3 – 0.8

X = 2.2

Putting this value to DE

IT IS ALSO A EQUILATERAL TRIANGLE

SO
5x + 4 = 5× 2.2 +4 =

11+4 = 15

All side will be 15 of triangle CD = DC = CE = 15
