A)
i) C(n)=42n
ii)C(n,x)=15n+0.25x

b)She plans to drive a total of 600 Km, therefore: x=600
Budget: C(n)=42n
Deluxe: C(n,x)=15n +0.25(600)=15n+150

Cost of Budget< Cost of Deluxe
42n<15n+150
42n-15n<150
27n<150
n<150/27
n<5.5 ⇒n<5

Answer: The maximum number of days would be 5 days.

A jar of 50 sour ball candies contains only 3 flavors. If there are 18 orange, 12 lemon, and 20 cherry sour balls, what is the p

Alla [95]

Option B. 12/ 125 is the answer.

Explanation

Total umber of sour ball candies = 50

Number of lemon candies = 12

Hence the probability to get a lemon candy is = 12/50

Number of cherry sour balls = 20

So, the probability to get a cherry sour ball = 20/50

So, to get the joint probability for a random selection to either get a lemon or cherry candy, we will multiply both the probabilities.

$\frac{12}{50}*\frac{20}{50}$

= $\frac{12}{125}$

If the total area of a dartboard 30 000 mm² and the area of the target is 700 mm²
The probability of obtaining a target can be written as:
P = 700 mm² / 30 000 mm²
P = 0.0233
P = 2.3%
Therefore the correct answer is option B.
This, assuming the shooter has no experience and rolls the dart randomly within the dartboard area.

The expression -320+15y represents a submarine that began at a depth of 15 feet below sea level and ascended at a rate of feet p

alex41 [277]

Step-by-step explanation:

Given an expression that represents a submarine that began at a depth of 15 feet below sea level and ascended at a rate of feet per minute is as follows :

-320+15y

We need to find the depth of submarine after 15 minutes.

Put y = 15 in the above expression.

-320+15y = -320+15(15)

= -320 + 225

= -95

Hence, the submarine is below sea level at 95 feet.
