A bin contains red balls and purple balls. A ball is selected at random and then placed back in the bin. The results are recorded after 10 trials, 50 trials, and 200 trials. The results are recorded in the table.Outcome| Number of trials
| 1050_200
Red | 5_36_152
Purple | 5_14_48

Based on the table, how many times can you expect that a purple ball will be selected in 400 tries?

Answers

Answer 1

Answer: In total, we have 5+14+48=67 purple balls in 10+50+200=260 trials, so based on our data, purple balls appear with probability 67/260=0.258, so we expect .258*400=103 purple balls to appear in the larger sample.

Answer 2

Solve the equation 4x^2-17x-15=0

Answers

$4x^2-17x-15=0\n 4x^2-20x+3x-15=0\n 4x(x-5)+3(x-5)=0\n (4x+3)(x-5)=0\n x=-(3)/(4) \vee x=5$

4x^2 - 17x - 15 = 0
(4x + 3)(x-5)
4x + 3 = 0
4x = -3
x = -3/4

Carol Byrd gets a student rate of $30.00 a month. There is a $250 deductible; but no coinsurance payment. She recently received treatment for a covered condition. The bill was $2,300.00. Carol's insurance company provided payment of 80% of the bill less the deductible. What was the company's payment? ________

What was Carol's total cost (ignoring the monthly premium)? ____________

Answers

Bill = $2,300
Deductible = $250
$2,300 - $250 = 2050
Take 80% of $2,050
80*2050 = $1640
Now $2050 - $1640
Coral = $410.

Hope this helps :)

Answer: The company's payment was $1640,

and Carol's total cost was $410.

Step-by-step explanation:

since we have given that

Bill amount = $2300

Amount of deductible = $250

Remaining amount is given by

$\$2300-\$250\n\n=\$2050$

Since Carol's insurance company provided paid 80% of the bill less the deductible.

So, the company's payment is given by

$(80)/(100)* 2050\n\n=0.8* 2050\n\n=\$1640$

And Carol's total cost after the payment of company is given by

$\$2050-\$1640=\$410$

Hence, the company's payment was $1640,

and Carol's total cost was $410.
