Then they all will equal the same thing when you divide them.

Example: A = 5   B = 20  20 divided by 5 = 4 
 C = 28    D = 7       28 divided by 7 = 4

Mariana [72]
Hi!

To solve this, we need to know how much the earrings and necklace cost together, then we need to know if it's more or less than how much she has ($20)

So first, add the costs together.

     7 . 5 8
+ 1 3 . 3 6
---------------
   2 0 . 9 4

The necklace and earrings cost $20.94 which is more than $20. 

The answer is no, Doreen does not have enough money.

Hope this helps! :)

Solve for y. 3y-10=5<br><br> show how you got the answer
skad [1K]

Answer:

5

Step-by-step explanation:

3y - 10 = 5

Move the 10 over to the other side by addition since it's being subtracted

3y = 5 + 10

3y = 15

now divide by 3 to get the y by itself

y = 15/3

y = 5

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

P(A) = 0.5

P(B) = 0.5

P(C) = 0.15

P(D) = 0.7

P(E) = 0.15

We need to find the independent events.

When we consider,

P(A∩D) = P(Event A and Event D) = 0.35

and

P(A) × P(D) = 0.7 × 0.5 = 0.35

We get that

P(A∩D)= P(A) × P(D) = 0.35

All other options are not satisfying the conditions of "Independent events".

Hence, Option 'B' is correct.
