Q and R are independent events. If P(Q)= 1/8 and P(R)=2/5 find P(Q and R).

1 answer:

3 0

Answer: 1/20
To find P(Q and R), you have to multiply P(Q) by P(R) to get the probability that both events will occur. P(Q) = 1/8, and P(R) = 2/5, so when multiplied together, you get 2/40. This simplifies to 1/20, meaning P(Q and R) = 1/20.

PLEASE HELP FAST!!!

grigory [225]

Answer:

x = 9

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

$\frac{x-1}{6}$ = $\frac{16}{12}$ ( cross- multiply )

12(x - 1) = 96 ( divide both sides by 12 )

x - 1 - 8 ( add 1 to both sides )

x = 9

Solve this step by step

Kaylis [27]

Step-by-step explanation:

the formula to calculate a circumference is

$x \times \pi$

(consider x as the diameter)

so I'll be noting the circumference as C alongside the circle's ranking

$ca = 6 \times 22 \div 7 \\ = 44 \div 7$

$cb = 7 \times 22 \div 7 \\ = 154 \div 7 \\ = 22$

$cc \: = 4 \times 22 \div 7 \\ = 88 \div 7$

hope I helped

What is the value of y in the equation 4(5y –8 –2) = 185 –15?

Rina8888 [55]

In an equation the Left hand side must equal the right hand side 4(5y-8-2)=185-15 20y-32-8=170 20y=170+32+8 20y=210 Therefore y=10,5 When you substitute the 10,5 and solve it on the left and side it's equal to 170 which is the answer on the right hand side
