Answer:

Gabriel should use 2.4 kilograms of the compost.

Step-by-step explanation:

Here, the ratio of Compost : Potting Soil  = 2 : 8

Also, total weight of the mix = 12 kg

Let us assume the common factor in the ratio  = m

So, the amount of compost used in the mix = 2 x m = 2m

Also, the amount of Potting soil used in the mix = 8 x m = 8m

Weight of Compost + Weight of potting soil = 12 kg

⇒ 2m + 8 m = 12

or, 10 m = 12

⇒ m = 12/ 10 = 1.2   , or m = 1.2

So, now the weight of the compost used = 2 m = 2 x 1.2 = 2. 4 kg

And the weight of potting soil used = 8 m = 8 x 1.2  = 9 . 6 kg

Hence, Gabriel should use 2.4 kilograms of the compost.

Consider randomly selecting a student at a large university, and let A be the event that the selected student has a Visa card an
poizon [28]

Answer:

We have that B = 0.3.

So

0.3 = b + (A \cap B)

However, b is a probability, which means that it cannot be negative. So no, P(A ∩ B) cannot be 0.5. It can, at most, be 0.3.

Step-by-step explanation:

Event A:

Probability that a student has a Visa card.

Event B:

Probability that the student has a MasterCard.

We have that:

A = a + (A \cap B)

In which a is the probability that a student has a Visa card but not a MasterCard and A \cap B is the probability that a student has both these cards.

By the same logic, we have that:

B = b + (A \cap B)

In this problem, we have that:

A = 0.6, B = 0.3

(a) Could it be the case that P(A ∩ B) = 0.5?

We have that B = 0.3.

So

0.3 = b + (A \cap B)

However, b is a probability, which means that it cannot be negative. So no, P(A ∩ B) cannot be 0.5. It can, at most, be 0.3.

Question 10
Anna11 [10]

Answer:

6,000 dollars

Step-by-step explanation:

We first need to find out how much it would cost Danielle for a month if she chose the second option

200 + 40 = 240

240 x 30 = 7,200

Now that we know how much Danielle would pay if she chose the second option, now we need to find out how much she <em>saved</em>.

7,200 - 1,200 = 6,000

So Danielle saved 6,000 dollars by choosing the first option instead of the second one.
