1 answer:

7 0

First you multiply 6(x) then you multiple 6(8)

Your equation should now look like this: 6x-48=72

Subtract 48 from both sides

Your equation should now look like 6x=120

Divide by 6

Answer:

$\frac{c-a}{2}$

Step-by-step explanation:

given $\frac{a}{2x-c}$ = - 1 ( cross- multiply )

- (2x - c ) = a ( distribute left side )

- 2x + c = a ( subtract c from both sides )

- 2x = a - c ( multiply both sides by - 1 )

2x = c - a ( divide both sides by 2 )

x = $\frac{c-a}{2}$

A teacher has found that the probability that a student studies for a test is 0.610.61, and the probability that a student gets

Ann [662]

Answer with step-by-step explanation:

Let

A=Student studies for a test

B=Student gets good grade on a test

The probability that a student studies for a test=P(A)=0.61

The probability that a student gets a good grade on a test=P(B)=0.79

The probability that both occur= $P(A\cap B)=0.56$

a.We have to find the events are independent

We know that if two events A and B are independent then

$P(A)\cdot P(B)=P(A\cap B)$

$P(A)\cdot P(B)=0.61\times 0.79=0.4819$

$P(A\cap B)\neq P(A)\cdot P(B)$

Hence, given events are not independent.

b.We have to find $P(B/A)$

$P(B/A)=\frac{P(A\cap B)}{P(A)}$

$P(B/A)=\frac{0.56}{0.61}=0.92$

c. We have to find $P(A/B)$

$P(A/B)=\frac{P(A\cap B}{P(B)}$

$P(A/B)=\frac{0.56}{0.79}=0.71$
