Slove 3 2/3 ÷ 1 1/4

Answers

Answer 1
Answer:

3 2/3 ÷ 1 1/4

Make the two mixed fractions into an improper fraction

Denominator times whole number. 3*3=9. Add 9 with the numerator. 9+2=11

1*4=4 . 4+1=5

11/3  ÷ 5/4

Flip over the second fraction only when dividing

11/3 *4/5

Multiply the numerator together. Multiply the denominator together.

11*4=44

3*5=15

44/15 or 2 14/15

Answer: 44/15 or 2 14/15
Answer 2
Answer:

Step-by-step explanation:

Change into improper fractions:

(11)/(3) / (5)/(4)

Change to a multiplication problem:

(11)/(3) * (4)/(5)

Simplify:

(44)/(15)

or

2 (14)/(15)

or 2.93333333333

Depends on how the question wants you to put it. You can put it as an improper fraction, a proper fraction, or as a decimal.

Hope this helped ; )

In a systematic review with a meta-analysis, researchers combine the results of each of the individual studies to create a larger sample size (and therefore greater power), then re-run the statistics to capture the true magnitude of the effect. The single-effect measure calculated and reported when the results from all the studies are combined is called what:______

Answers

The single-effect measure calculated and reported is called: Summary statistic

The summary statistic is use to derive a more centralized result ( measure of central tendency ) of a group of data contained in a data set. given that all the results of each individual studies are collected to create a larger sample.

The single-effect measure that will be calculated and reported when this larger sample size is re run to capture the true magnitude is termed the summary statistic of the individual studies.

Hence we can conclude that the single-effect measure calculated and reported is called summary statistic

QuestionAlice drove from the town of Everett to the town of Gage at an average speed of 45 miles per hour. If she
Grove for 40 minutes, how far did she travel? (1 hour = 60 minutes)

Answers

45 miles per hour is equal to 45 miles per 60 minutes. Let’s make it into a ratio, 45:60, and simplify it to 3:4 by dividing each by 15. Now, we can multiply the simplified ratio by 10 to get 30:40, which translates to 30 miles in 40 minutes.

Answer: 30 miles

Determine whether and are parallel, perpendicular, or neither. W(–4, 5), X(8, –1), Y(6, –2), Z(1, –7)

Answers

Answer: The question is that of Line WX and YZ are parallel or perpendicular, not WZ and XY unlike the other given answer.

THE ANSWER IS NEITHER

Step-by-step explanation:

See moc up i made. The two lines don't even intersect, I.E the answer is neither!

Answer:

You have not mentioned the joining points so I have joined the points WZ and XY and plotted in the graph. It seems that the lines WZ and XY are perpendicular.

Q 3.28: To create a confidence interval from a bootstrap distribution using percentiles, we keep the middle values and chop off a certain percent from each tail. Indicate what percent of values must be chopped off from each tail for a 97% confidence level. A : We keep the middle 97% of values by chopping off 1.5% from each tail. B : We keep the middle 1.5% of values by chopping off 97% from each tail. C : We keep the middle 3% of values by chopping off 97% from each tail. D : We keep the middle 3% of values by chopping off 1.5% from each tail. E : We keep the middle 97% of values by chopping off 3% from each tail.

Answers

Answer:

A : We keep the middle 97% of values by chopping off 1.5% from each tail.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = (1-0.97)/(2) = 0.015

This means that for a 97% confidence interval, 1.5% of each tail is removed, while the middle 97% of values are kept.

So the corect answer is:

A : We keep the middle 97% of values by chopping off 1.5% from each tail.

Write it in a standard form

Answers

we know that

To write a linear equation in standard form, move each variable term to the left side of the equation and simplify.Ax+By=C

so
Y=1/2x-5--------> (1/2)x-y=5
where
A=1/2
B=-1
C=5

the answer is
 (1/2)x-y=5
