If a varies directly as b, and a = 28 when b = 7, find b when a = 5.

Reika [66]

Answer: Option B.

$b=\frac{5}{4}$

Step-by-step explanation:

If a varies directly with b then when a increases b it also increases by a factor k.

Then we can write that

$a = kb$

We know that when a = 28 then b = 7. So

$28 = k * 7$

$k=\frac{28}{7}$

$k=4$

Therefore the equation of proportionality is:

$a=4b$

So when $a=5$ then:

$5=4b\\\\b=\frac{5}{4}$

Answer:

(a)117000 (b)1/117000 (c)116999/117000

Step-by-step explanation:

(a)There are 26 letters, hence 26 options for the first character

There are 9 options for the second character, because, you can place 1,2,3,4,5,6,7,8,or 9.

For the third character you can have 10 options, since, you can 1 through 9 and 0.

The 4th one has 10 options too since the same terminology is used for the 3rd digit as the 4th one.

For the last digit, You have 5 options,0, 2, 4, 6, and 8.

Hence, the answer is 26*9*10*10*5 = 117000

(b)There is only 1 correct code, so the chance of getting it right is 1/117000.

(c)There are 117000-1 ways oh getting it wrong, so 116999/117000.

Answer: 0.1677

Step-by-step explanation: Two events are said to be independent if the probability that one event occurs does not affect the probability of the other event

occurring, i.e in coin tossing the event of getting a head does not affect the event of getting a tail. Given two

events, A and B that are independent, probability they all occur is given by:

P(A) x P(B)

There are 3 Vice presidents hence the probability of a vice president not being invited = 1 -1/5 = 0.8

The event of inviting the vice presidents are independent, hence :

P(A vice president has not been invited for the last 8 Lakers home games) =

0.8^8 = 0.1677

Hence P(this could be due to chance) =

0.1677
