Answer:

A- Fiona’s,

B- $6

B- Heidi’s

Step-by-step explanation:

Here, the equation that represents the value of Fiona’s coin, in dollars, x years later is,

f(x) = 3x + 12

Initially, x = 0,

Thus, the value of the coin when Fiona bought,

f(0) = 3(0) + 12 = $ 12,

Also, the graph represents the value of Heidi’s coin, in dollars, x years later.

By the graph, if x = 0 ( initially ),

y = 6

That is, when Heidi bought the coin its value is $ 6,

Also, 12 - 6 = 6

Hence, when they bought their coins, Fiona’s was worth $6 more than Heidi’s coin.

A patient needs a total dose of 50 grams of albumin. The pharmacy has 50 m
garik1379 [7]

Answer:

4,000 bottles.

Step-by-step explanation:

Given that the patient needs a total dose of 50 grams of albumin, and the pharmacy has bottles of 50 milligrams with 25% albumin, to determine how many bottles the patient should purchase the following calculation must be performed:

1 g = 1000 mg

50 g = 50,000 mg

50 x 0.25 = 12.5

50,000 / 12.5 = X

4,000 = X

Therefore, the patient must purchase 4,000 bottles to obtain the required dosage.

If you flip 2 coins, what is the probability of getting exactly 2 heads
Ahat [919]

Answer:

This states that the probability of the occurrence of two independent events is the product of their individual probabilities. The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25.

Step-by-step explanation:

The probability of getting 2 heads with 2 coins can be broken into 2 steps:

The first coin must show Heads AND

the second coin must show Heads.

p(h,h)= P(H) <----- and means multiply

P(H) x P(H)= 1/2 x 1/2 =1/4
