Answer:

r = 4.5%

Step-by-step explanation:

Formula:

I = Prt

r = I/(Pt)

Given:

I = 662.29

P = 4205

t = 3.5

Work:

r = I/(Pt)

r = 662.29/(4205 * 3.5)

r = 662.29/14717.5

r = 0.045

r = 4.5%

The probability of both children receiving a tablet is 15%.

We have given that

Age of Children P(Tablet) P(Laptop)

Less than 10    0.3   0.02

10-17     0.5    0.4

<h3>What is the probability?</h3>

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Probability of both children receiving a tablet is

0.3*0.5 = 0.15 = 15%

Therefore, the probability of both children receiving a tablet is 15%

Therefore option b is correct.

Step-by-step explanation:

"End behavior" generally refers to the behavior as the independent variable (x) gets large in the positive or negative directions. Here, the curve for large magnitude x flattens out and approaches 1. So, we say ...

he graph represents the function f(x) = x2 + 3x + 2. If g(x) is the reflection of f(x) across the x-axis, g(x) = . (Write the fu
kifflom [539]

if g(x) is the reflection of f(x) across the x-axis that would mean g(x)= - f(x)

so that would mean you have to change all the signs of f(x) to negative

Ans: g(x)= - x^2 - 3x - 2
