Given P(A)=0.3P(A)=0.3, P(B)=0.63P(B)=0.63 and P(B|A)=0.79P(B∣A)=0.79, find the value of P(A\text{ and }B)P(A and B), rounding to the nearest thousandth, if necessary.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

468

step-by-step explanation:

y -5 = (-1/4)(x + 8)

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
