PLEASE HELP!!!!!! I need help on this problem

Thepotemich [5.8K]

Answer:

185 minutes.

Step-by-step explanation:

It is possible to model an equation for this, such that

$0.10x + 14.80 = 0.08x + 18.50$

where x represents the number of minutes.

Then, you solve for x:

$0.10x + 14.80 = 0.08x + 18.50 \\ 0.02x = 3.70 \\ x = \frac{3.70}{ 0.02} \\ x = 185$

A student wants to estimate the mean score of all college students for a particular exam. First use the range rule of thumb to m

Wewaii [24]

Answer:

See explanation below

Step-by-step explanation:

range = 2200 - 300 = 1900

To find standard deviation, we have:

standard deviation = range/4 = $\frac{1900}{4}$ = 475

The range rule of thumb estimate for the standard deviation is 475

Given:

Standard deviation, $\sigma$ = 475

Margin of Error, ME = 100

$\alpha$ = 1 - 0.90 = 0.10

Za/2 = Z0.05 = 1.64

Find sample size, n:

n ≥ $[Z_\alpha_/_2 * (\frac{\sigma}{ME})]^2$

n ≥ $[1.64 * (\frac{475}{100})]^2$

n ≥ 60.68

≈ 61

Minimun sample size,n = 61

Pls help i neeed to get my grade up badly

amm1812

Step-by-step explanation:

12 - 1/2r = ( 13 - 3/2r ) - ( 1 - r )

r - 13/6 = ( 7r - 3/2 ) - ( 2/3 + 6r )

13r + 20 = ( 6r + 7 ) + ( 13 + 7r )

-12 + r = ( -8 - r ) + ( 2r - 4 )
