Let E be the event that a randomly chosen person exercises. Let D be the event that a randomly chosen person is on a diet. Ident

Sunny_sXe [5.5K]

Answer:

d) P(D|E)

Step-by-step explanation:

E = person exercises

D = person on a diet

Given the expression :

Of all the people who exercise, the probability that a randomly chosen person is on a diet.

This simply refers to a conditional probability whereby the subset from which the probability that a randomly chosen person is on diet is to be calculated is the subset of those who exercise.

In statistical parlance, the statement is expressed as ; the probability of A given B = P(A|B)

In this scenario, we say; the probability that a randomly chosen person is on a diet Given that the person exercise ; P(D|E)

Hence, the answer is D.

Find the first four terms of the sequence given by the following. aₙ=43-3(n-1) n=1,2,3. . .

Serggg [28]

Given :-

The general term of a sequence is given by aₙ=43-3(n-1) .

To Find :-

The first four terms of the sequence.

Solution :-

The given expression is $/$

→ aₙ=43-3(n-1)

where n > 0

Finding the first term :

Substituting n = 1 , we have ,

→ T1 = 43 - 3(1-1)

→ T1 = 43 - 3*0

→ T1 = 43 - 0 = 43

Finding the second term :

Substituting n = 2 , we have,

→ T2 = 43 -3(2-1)

→ T2 = 43 -3*1

→ T2 = 43 -3 = 40

Finding the third term :

Substituting n = 3 , we have,

→ T3 = 43 -3(3-1)

→ T3 = 43 -3*2

→ T3 = 43 -6 = 37

Finding the fourth term :

→ T4 = 43 -3(4-1)

→ T4 = 43 -3*3

→ T4 = 43-9 = 34

Hence the first four terms of the sequence are 43 , 40 , 37 and 34 .

I hope this helps . Let me know if you need further clarification .

A table is on sale for $289, which is 32% less than the regular price.

prohojiy [21]

Answer:

$R = \$903.125$

Step-by-step explanation:

Given

$Selling\ Price = \$289$

$Rate = 32\%$

Required

Determine the regular price (R)

From the question, we understand that:

$R * 32\% = \$289$

So, we have:

$R * 0.32 = \$289$

$R = \frac{\$289}{0.32}$

$R = \$903.125$

Hence, the regular price is $903.125
