a survey was taken of children between the ages 7 and 12. let A be the event that the person rides the bus to school, and let B

galben [10]

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

Midpoint rule with given value

jeyben [28]

9514 1404 393

Answer:

M₅ = 1.6570

Step-by-step explanation:

The basic idea is to find the function values at x ∈ {1.1, 1.3, 1.5, 1.7, 1.9}, add those values, and multiply the result by 1/5. Those x-values are the midpoints of intervals 0.2 units wide, between x = 1 and x = 2. The width 0.2 is the total interval width (2-1=1) divided by n = 5.

The calculation and results are shown in the attachment. Rounded to 4 decimal places, the integral is ...

M₅ = 1.6570

The actual integral is about 1.6574, so this is pretty close.
