son4ous [18]

Answer:

The statement is true about whether A and B are independent eventa is fourth option:

A and B are not independent events because P(A/B)=0.375 and P(A)=0.25

Step-by-step explanation:

Let A be the event that the person rides the bus to school, then:

P(A)=75/300

P(A)=0.25

Let B be the event that the person has 3 or more siblings, then:

P(B)=24/300

P(B)=0.25

P(A/B)=9/24

P(A/B)=0.375

Like P(A/B)=0.375 is different to P(A)=0.25 the events are not independent

Answer. Fourth option:

A and B are not independent events because P(A/B)=0.375 and P(A)=0.25

(3x+4)^3=2197 solve this equation

Burka [1]

(3x + 4)³ = 2197

Taking the cube root in this case is easier, although we can do it the extended way which is complicated.

$\sqrt[3]{(3x+4)^3}$ = $\sqrt[3]{2197}$
3x + 4 = 13

Now solve normally.

subtract 4
3x + 4 = 13
-4 -4

3x = 9
Divide by 3 to isolate 3

$\frac{3x}{3} = \frac{9}{3}$
3 and 3 cancels out

x = 3
