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]

A car's appreciation depends on the it's rarity and and popularity. Unfortunately, it usually takes time for a car to appreciate, at least 20 years, when people become nostalgic and are willing to pay more for a car which is usually considered a classic by that time.

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

How Many hurdles did Eli jump over?

Answer:

(6x+3)=120

6x=120-3

6x=117

x=117/6

x=19.5

(7x-19)=120

7x=120+19

7x=139

x=139/7

x=19.85

Answer:

2x^2 + 4x - 64

Step-by-step explanation:

it is telling us to add the functions together so we use this equation:

2x^2 + 7x - 5 + (-8^2) - 3x + 5

after combining like terms we get

2x^2 + 4x -8^2

and then lastly we square the -8 and get

2x^2 + 4x - 64

Step-by-step explanation:

A = ℓ × w

A = 8 × 4

A = 32 cm²

A = ½ × 5 × 12

A = 5 × 6

A = 30 cm²

Answer:

slope = undefined

Step-by-step explanation:

1. The formula to find a slope of a line given two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].

2. Since anything divided by 0 = undefined, the slope is undefined.

Answer:

Step-by-step explanation:

Hi there!

Given;

base (b) = 6.5 inches

height (h) = 8 inches

Now;

[tex]area= \frac{1}{2}*b*h[/tex]

[tex]area (a)=\frac{1}{2}*6.5*8[/tex]

area = 52/2

Therefore, the area of the triangle is 26 [tex]inches^{2}[/tex].

Hope it helps!

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).

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.
