3 and 1/3=3+1/3
3 and 3/4=3+3/4

add them
3+1/3+3+3/4=3+3+1/3+3/4=6+1/3+3/4
to add fractions, make denomenators the same

1/3 times 4/4=4/12
3/4 times 3/3=9/12
1/3+3/4=4/12+9/12=13/12=1 and 1/12
6+1/3+3/4=6+1+1/12=7+1/12
7 and 1/12 is 1/12 more than 7

beat her goal by 1/12 mile

Which of the following statements is true in a one-way ANOVA? a. The critical value of the test will be a value obtained from th
Musya8 [376]

Answer:

d) All of the above

Step-by-step explanation:

A one way analysis of variance (ANOVA) test, is used to test whether there's a significant difference in the mean of 2 or more population or datasets (minimum of 3 in most cases).

In a one way ANOVA the critical value of the test will be a value obtained from the F-distribution.

In a one way ANOVA, if the null hypothesis is rejected, it may still be possible that two or more of the population means are equal.

This one way test is an omnibus test, it only let us know 2 or more group means are statistically different without being specific. Since we mah have 3 or more groups, using post hoc analysis to check, it may still be possible it may still be possible that two or more of the population means are equal.

The degrees of freedom associated with the sum of squares for treatments is equal to one less than the number of populations.

Let's say we are comparing the means of k population. The degree of freedom would be = k - 1

The correct option here is (d).

All of the above

If two angles are supplementary and one angle measures 47°, what is the measure of the other angle? 43° 133° 53° 47°
Rama09 [41]

Answer:

x = 133

Step-by-step explanation:

Supplementary angles add to 180 degrees. Call the unknown angle x

47 +x = 180

Subtract 47 from each side

47-47+x =180-47

x = 133
