A purchaser of electric relays buys from two suppliers, A and B. Supplier A supplies two of every three relays used by the compa
Reptile [31]

Answer: Our required probability is 0.3162.

Step-by-step explanation:

Since we have given that

n = 60

Probability of success = \dfrac{2}{3}

Probability that at most 39 of these relays come from supplier A would be

P(X\leq 39)=binomcdf(60,\dfrac{2}{3},39)=0.3162

Hence, our required probability is 0.3162.

Pamela drove her car 99 kilometers and used 9 liters of fuel. She wants to know how many kilometers (k) she can drive with 12 li
masya89 [10]

Answer:

132 kilometers

Step-by-step explanation:

Given: Pamela drove her car 99 kilometers and used 9 liters of fuel.

To find: Number of kilometers Pamela drove in 12 liters of fuel.

Solution:

It is given that Pamela drove her car 99 kilometers and used 9 liters of fuel. Also the relationship between kilometers and fuel is proportional.

So, let us assume that she can travel x kilometers in 12 liters of fuel.

By proportionality we have,

99:9 :: x:12

\frac{99}{9} =\frac{x}{12}

11=\frac{x}{12}

x=12\times11

x=132

Hence, she can travel 132 kilometers in 12 liters of petrol.
