Alice is deciding where to go on her next trip. She is reviewing some information packets. She has packets advertising European trips numbered 1,2,3, packets advertising African trips numbered 1,2,3,4,5,6, and packets advertising South American trips numbered 1,2. If a single packet is picked at random, what is the probability that the packet is advertising a South American trip AND has an odd number?
Provide the final answer as a fraction.
Answers
Answer:
1/11
There are a total of 3+6+2=11 packets. Of these, there is 1 card that is advertising a South American trip and has an odd number, so the answer is 1/11.

The equation y = 0.7x represents the distance Henry hikes in miles over time in hours. The graph represents the rate that Clark hikes. Determine which hiker is faster. Complete the explanation.
Answers
Answer:
Henry’s unit rate is 0.7 miles per hour. Clark’s unit rate is 1.5 miles per hour . So, Ckark is faster.
Step-by-step explanation:
Distance covered by Henry is represented by y = 0.7x, where x = time (hrs), and y = distance (miles).
Distance covered in 1 hour by Henry would be:
y = 0.7(1) = 0.7 miles per hour
Distance covered by Clark in 1 hour = 1.5 miles per hour
Ckark covers more miles per hour than Henry covers in one hour, therefore, Ckark is faster.
Hope this helped!

Suppose a life insurance company sells a $230,000 one-year term life insurance policy to a 24-year-old female for $200. The probability that the female survives the year is 0.999569. Compute and interpret the expected value of this policy to the insurance company. The expected value is $ (Round to two decimal places as needed
Answers
Suppose a life insurance company sells a $150,000 one-year term life insurance policy to a 23-year-old female for $260 the expected value of this policy to the insurance company will be:$198.35
Expected value=(260×0.999589)-(150,000-$260)×(1-0.999589)
Expected value=259.89314-149,740×0.000411
Expected value=$198.35
Interpretation of the Expected value:
Based on the above calculation the insurance company is expect to make an average profit of $198.35 on every 23-year-old female it insured for 1 year.
Inconclusion Suppose a life insurance company sells a $150,000 one-year term life insurance policy to a 23-year-old female for $260 the expected value of this policy to the insurance company will be:$198.35

Step-by-step explanation:
This is true, because you have to convert the fraction (3/5) into the same denominator as (8/15).
3/5 = 9/15
9/15 is greater than 8/15 so, 8/15 is less than 9/15

(7b-2)
(3b+2)°
Answers
Answer:
b = 10
Step-by-step explanation:
"7b - 2" is supplementary to "3b + 2"
7b - 2 + 3b + 2 = 180
7b + 3b - 2 + 2 = 180
10b + 0 = 180
10b/10 - 180/10
b = 18

21. Explain why the exponents cannot be added in the product 123. 113.
Why the exponents cannot be added in the product 12 to the power of 2 • 11 to the power of 3
Answers
9514 1404 393
Answer:
the bases are different
Step-by-step explanation:
It is useful to remember that an exponent signifies repeated multiplication:
12² = 12×12 . . . . 2 factors of 12
11³ = 11×11×11 . . . 3 factors of 11
In the product ...
12² × 11³ = 12×12×11×11×11
there are no factors that are repeated 2+3=5 times. It makes no sense to add any exponents in this product.

Find the Minimum value of C=4x+3y subject to the following constraints
Answers
Answer:
So: C = 4x + 3y > 12,5 × 4 + 1,5 × 3 = 50 + 4,5 = 54,5
Conclusion: C > 54,5
9514 1404 393
Answer:
C = 6 is the minimum
Step-by-step explanation:
2-variable constraint problems are often easy to solve graphically. The overlap of each of the solution regions defines a "feasible region." The vertices of that region will be candidates for the (x, y) values that satisfy the objective function.
The three constraints define a feasible region with four vertices:
(0, 2)(0, 4)(5, 3)(3, 0)The most likely candidates for minimizing C are (0, 2) and (3, 0). The corresponding values of C are ...
(0, 2): C = 4·0 +3·2 = 6
(3, 0): C = 4·3 +3·0 = 12
The minimum value of C is 6 at (x, y) = (0, 2).
_____
Additional comment
The line representing the objective function will be closest to the origin when the objective function is minimized. Once we can see the slope of it on the graph, we can determine the feasible region boundary point that will place the line closest to the origin.
