I'll get you started:

mean = np = (500)(.56) = ?

standard deviation = √npq = √(500)(.56)(.44) = ?

Note: q = 1 - p

Finish the calculations.

To find z-score:

z = (x - mean)/sd

Note: x = 250

Once you have the z-score, look in a z-table using the score to find your probability. Remember that the question is asking "at least 250" when looking at the table.

Ariana just started a running plan where she runs 8 miles the first week and then

Alex

Answer: 12 miles

Step-by-step explanation:

Hi, to answer this question we have to write a growth equation.

Total miles = 8 (1 +0.05)^9 = 12.41 =12 miles

Where 8 is the initial miles she run, since is increasing each week by 5% we have to multiply it by 1+ percent increase rate in decimal form (1+0.05) to 9th power (number of weeks)

She will run 12 miles in 9 weeks.

What are the solutions of the equation f(x)=g(x) 0 1 2 3 4

Alex

Answer:

(1, 0 ) and (3, 6 )

Step-by-step explanation:

we are looking in the table for values of x that give both f(x) and g(x) the same value.

x = 1 → f(x) = g(x) = 0

x = 3 → f(x) = g(x) = 6

then the solutions to f(x) = g(x) are

(1, 0 ) and (3, 6 )
