An IQ test is designed so that the mean is 100 and the standard deviation is 10 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with ​99% confidence that the sample mean is within 8 IQ points of the true mean. Assume that σ=10and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. The required sample size is

Answers

Answer:

sample size = 10

it is not practical because we can't draw a conclusion for a complete population based on the sample size of 10 people

Step-by-step explanation:

mean = 100

standard deviation = sigma = 10

confidence level = 99%

The z-score for 99% confidence level = z = 2.58

mean IQ is within 8 IQ points so:

error = E = 8

sample size = n (we don't know it)

Since the distribution is normal, we can use the formula of margin of error for z-distribution to calculate the missing sample size:

[tex]E = z * \frac{sigma}{\sqrt{n} } \\\sqrt{n} = z * \frac{sigma}{E} \\\\\sqrt{n} = 2.58*\frac{10}{8} \\\\\sqrt{n} = \frac{25.8}{8} \\\\n = (\frac{25.8}{8} )^{2}\\n = 10.4\\[/tex]

An elevator rises steadily up a skyscraper. After 4 s it is 33 m above the ground, 2 s later it is 47 m above the ground. Which equation models its position, y, with respect to time, x?

Answers

Answer:

The 2nd motion eqn.

S = ut + 1/2gt²

where, u is the initial speed of the elevator

S = position

and t = x

y = ux + 1/2gx²

y = 1/2gx² + ux

since the elevator started at 0 as initial speed(that is at rest)

y = 1/2gx² + 0

y = 1/2gx² is the eqn

What is the image of the point (7,4) after a rotation of 90° counterclockwise about
the origin?

Answers

Answer:

When rotating a point 90 degrees counterclockwise about the origin the point (7,4) becomes (-4,7).

Step-by-step explanation:

In other words, just switch x and y and make y negative.

The point will be inverted when (7,4) is rotated 90° counterclockwise i.e., the new point will be (4,7).

It is given that a point (7,4) is rotated 90° counterclockwise about origin.

We have to find the new point after rotation.

What do you mean by rotation counterclockwise ?

If something is moving counterclockwise that meant it is moving in the opposite direction to the direction in which the hands of a clock move.

As per the question ;

A point (7,4) is rotated of 90° counterclockwise about origin.

Let's assume (7,4) = (x , y)

If we rotate it 90°counterclockwise ; then the point will be inverted ; i.e.,

(x , y ) ⇒ ( y , x)

So ;

( 7 , 4 ) = ( 4 , 7 )

So ;

The new point will be ;

= ( 4 , 7 )

Thus , the point will be inverted when (7,4) is rotated 90° counterclockwise i.e., the new point will be (4,7).

PLEASE HELP

Answers

Answer:

We have been given that a salesperson works 40 hours per week at a job where he has two options for being paid. Option A is an hourly wage of $25. Option B is a commission rate of 8% on weekly sales.

First of all we will find amount earned by salesperson with option A.

The salespersons earns $1000 through option A.

Let x be the amount of weekly sales.  

8% of x should be equal to 1000 for salesman to earn the same amount with the two options.

     

Therefore, the salesman needs to make a weekly sales of $12,500 to earn the same amount with two options.We have been given that a salesperson works 40 hours per week at a job where he has two options for being paid.
