7. market research shows that 30% of consumers are likely to purchase an electronic tablet for younger children under age 10. however, only 2% of consumers are likely to buy a laptop for children under age 10. on the other hand, for children ages 10 - 17, 50% of consumers are likely to buy a tablet and 40% are likely to buy a laptop. if a family has a five-year-old son and a 13-year-old daughter, what is the probability of both children receiving a tablet?

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
