Find "n" if the Standard Error of M is 4 and the population standard deviation is 16.

Mathematics

ZanzabumX [31]2 years ago
3 0

Answer:

n = 16

Step-by-step explanation:

Givem that :

Population Standard deviation , σ = 16

Sample size, n =

Standard Error, S. E = 4

To obtain the standard Error, S. E, we use the relation :

S.E = σ / √n

4 = 16 / √n

√n * 4 = 16

Divide both sides by 4

(√n * 4) / 4 = 16 / 4

√n = 4

Square both sides

n = 4²

n = 16

Hence, Sample size = 16

What is the equation of the line that passes through the point (6,14) and is parallel to the line with the following equation? y
Gekata [30.6K]

Answer:

y=\displaystyle-\frac{4}{3}x+22

Step-by-step explanation:

Hi there!

<u>What we need to know:</u>

  • Linear equations are typically organized in slope-intercept form: y=mx+b where <em>m</em> is the slope and <em>b</em> is the y-intercept
  • Parallel lines always have the same slope (<em>m</em>)

<u>Determine the slope (</u><em><u>m</u></em><u>):</u>

<u />y=\displaystyle-\frac{4}{3}x -1<u />

The slope of the given line is \displaystyle-\frac{4}{3}, since it is in the place of <em>m</em> in y=mx+b. Because parallel lines always have the same slope, the slope of a parallel line would also be \displaystyle-\frac{4}{3}. Plug this into y=mx+b:

y=\displaystyle-\frac{4}{3}x+b

<u>Determine the y-intercept (</u><em><u>b</u></em><u>):</u>

y=\displaystyle-\frac{4}{3}x+b

To find the y-intercept, plug in the given point (6,14) and solve for <em>b</em>:

14=\displaystyle-\frac{4}{3}(6)+b\\\\14=-8+b\\b=22

Therefore, the y-intercept of the line is 22. Plug this back into y=\displaystyle-\frac{4}{3}x+b:

y=\displaystyle-\frac{4}{3}x+22

I hope this helps!

Bob and Jimmy went to the gym to lift weights. Jimmy lifted twice as much as Bob. Together they lifted 51lbs. How much did each
Darina [25.2K]
I broke it all the way day half of 51 is 25 in a half and half of 25 is 12 in half so if Jimmy lifted twice as much he may have lifted 25 in a half and bob left 12
