A bag contains 12 pieces of candy, all the same size. Four of the candies are lemon flavored. Which approach would be best to find the probability of randomly drawing a lemon-flavored piece of candy? A. subjective approach B. classical approach C. relative frequency approach

Answers

Answer 1

Answer:

Answer: Relative frequency approach

Step-by-step explanation:

In relative frequency of an event is defined as the number of times that the event occurs during experimental trials, divided by the total number of trials conducted in the given event.

That is if there are total 9 boys in which 4 are from Us.

Then the probability of choosing a boy of Us= Number of boys from US/ total number of boys= 4/9

In our question, we have total pieces of candy= 12

In which lemon-flavored piece of candy = 4

the probability of randomly drawing a lemon-flavored piece of candy= 4/12

= lemon-flavored piece of candy/ total pieces of candy

Thus, we are using relative frequency approach for finding the probability.

Therefore, Option C is correct.

Answer 2

Answer:

Classical approach.

I just took the test.

The area of the mojave desert is 25,000 square miles. A scale drawing of the mojave desert has an area of 10 square inches. What is the scale of the map? i need a middle explanation because if not then my teacher will think i cheated and give me an f and my parents will not allow me to fail so could i please get a 7th grade explanation?

Answers

The scale of the map will be: 50 miles = 1 inch or 50 : 1

Explanation

Actual area of the Mojave desert is 25,000 square miles and the scale drawing has an area of 10 square inches.

Suppose, the scale of the map is: $x$ miles = 1 inch

So, 1 square inches = $x^2$ square miles

and 10 square inches = $10x^2$ square miles

So, the equation will be .....

$10x^2=25000\n \n x^2= 2500\n \n x=√(2500)=50$

Thus, the scale of the map will be: 50 miles = 1 inch or 50 : 1

The graph of g(x) contains the point (7,12). What point must be on the graph of the function f(x) if g(x) = 2f(x-3)+4? How do you solve for this?

Answers

first take out 2 as a factor
g(x) = 2[f(x-3)+2]

f(x-3) means a shift of +3 in the x direction
+2 means a shift of +2 in the y direction
2[f] means a stretch of scale factor 2 in the y direction

so (7+3, 2(12+2)) -> (10,28)

Write the equation of each line in the indicated form 1. Standard form. Slope=8/3;(-2,0)

2. Point-slope form (-5,6) and(3,-10)

Answers

1. standard form is y=mx+b so I will use point slope to start
y-0=8/3(x+2), y=(8/3)x+(16/3)
2.Must solve for slope first, (y2-y1)/(x2-x1), -10--5/3-6= -5/-3= 5/3
so slope is 5/3, point slope is y-y1=m(x-x1), y-6=5/3(x+5)

What multiplies to 378 and adds to -51

Answers

Your answer would be -9 & -42.

Here's why ...
(-9)*(-42) A negative times a negative equals a positive (378).
Now, -9-42=-51 & you add these because you have two negatives.

Hope this makes sense & helps you ! (:
