The probability that a student uses the Internet, given that he or she is in eighth grade is 8/13 or 0.66

<u>Step-by-step explanation:</u>

<u>From the table shown:</u>

The students in the eighth grade = 13
The eighth grade students using internet = 8

P(student uses the Internet in eighth grade) = P(eighth grade students using internet) / P(total students in the eighth grade)

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $1790 and his st

stiv31 [10]

Answer:

20.7%

Step-by-step explanation:

Amount of stock increased in Company A = 20% of 1790

= 0.20 * 1790 = $ 358

Investor's stock in company A this year = 1790 + 358 = $ 2148

Amount of stock increased in Company B = 22% of 1000

= 0.22 * 1000= $ 220

Investor's stock in company B this year = 1000 + 220 = $ 1220

Total amount in investor's stock account = 2148 + 1220 = $ 3368

Increased amount = 3368 - 2790 = $ 578

Increase percentage = $\frac{578}{2790}*100$ = 20.71

= 20.7%
