A bag contains 30 cookies: 6 vanilla, 12 chocolate, and 12 oatmeal. What is the probability that an oatmeal is randomly selected?
A) 1/4

B) 1/5

C) 1/6

D) 2/5

Answers

Option: (D). The Probability that an oatmeal is randomly selected is 2/5.

What is Probability?

Probability is Possibility. Probability deals with" an occurrence of an Random event. It values varies from 0 to 1".

According to the question,

Number of vanilla = 6

Number of chocolate = 12

Number of Oatmeal = 12

Formula for Probability of an event to occur P(E) = [tex]\frac{Number of favourable event}{Total Number of an event}[/tex]T.

Total number of an Outcomes = 30

P(E) = [tex]\frac{12}{30}[/tex]

The probability of selecting an oatmeal cookie from a bag of 30 cookies (6 vanilla, 12 chocolate, and 12 oatmeal) is 2/5, which is answer choice D.

The student's question involves calculating the probability of selecting an oatmeal cookie from a bag containing multiple types of cookies. The total number of cookies is 30, comprising 6 vanilla, 12 chocolate, and 12 oatmeal cookies. To find the probability of selecting an oatmeal cookie, we use the formula:

Probability (selecting an oatmeal cookie) = Number of oatmeal cookies / Total number of cookies.

This gives us:

Probability (selecting an oatmeal cookie) = 12 / 30 = 2 / 5

So, the probability that an oatmeal cookie is randomly selected is 2/5, which corresponds to answer choice D.

Trent is fishing from a pier. ●The tip of his fishing rod is 53 ¾ feet above the surface of the water. ●The hook on the end of the fishing line is directly below the tip of the fishing rod 12 ⅔ feet below the surface of the water. Trent estimates that the distance between the tip of his fishing rod and the hook is less than 65 feet. Is Trent’s estimate reasonable? Explain your answer. HELP Please

Answers

I would say yes and no because estimations aren't exact, they're close to the correct value. Trent's estimation is correct since 53+12=65, if we were looking for the exact distance, Trent would be wrong because there are fractions too, so the exact value would be 66 (5/12) or 65 (17/12).

Expand the polynomial:

Expand the following:

o decorate his bedroom, Mike spent $41.64 on new bedding, $36.84 on paint, and $72.49 on accessories. About how much did he spend to decorate his bedroom?

Answers

He spent 150.97 hope this helps :) have a good day

Answer:

Mike spent $150 on his decorations.

Step-by-step explanation:

In order to find the amount of money Mike spent on his decorations you must add all the costs together.

$41.64 + $36.84= $78.48

$78.48 + $72.49= $150.97

Then you round 150.97 to 151, which is also close to 150.

in a first aid kit the ratio of large bandages to small bandages is 5 to 2. Based on this ratio, how many large bandages are in the kit if there are total of 60 bandages?

Answers

The best way to answer this question is to set up the first sentence as a ratio of large bandages to total bandages. You would write 5 large bandages to 7 total bandages to 7 total bandages.  Then you would make this equivalent to x number of large bandages to 60 total.  It would look like this 5:7 = x:60.  You could use cross products to multiply 60 by 5 to get 300.  7 times x also should equal 300.  Unfortunately, this example will not leave us with a whole number of bandages, but 300/7 is a repeating decimal or a mixed number (42 6/7 large bandages).

By separating between whole numbers and fractions, we will see that the sum is equal to 2 + 11/12.

How to add mixed numbers?

Here we want to perform the sum:

We separate between whole and fractions, so we get:

(3 - 2 + 1) + (1/3 - 1/4 + 5/6)

The left part is easy: 3 - 2 + 1 = 2

The right part needs to find a common denominator, we will use 12.

1/3 - 1/4 + 5/6 = 4/12 - 3/12 + 10/12 = 11/12

Then the sum is:

find two consecutive odd integers such that 36 more than the lesser is three times the greater

Answers

Two consecutive odd integers means there's a difference of 2 between the numbers. More than the lesser is adding to the lower integer (x). The greater is the larger integer (x+2). "Is" means equals. Times means multiply.

x= first integer
x+2= second integer

x + 36= 3(x + 2)
multiply 3 by everything in parentheses
x + 36= 3x + 6
subtract x from both sides
36= 2x + 6
subtract 6 from both sides
30= 2x
divide both sides by 2
15= x

x= 15 first consecutive odd integer

x+2= second consecutive odd integer
15+2= 17

ANSWER: 15, 17

Hope this helps! :)

Final answer:

To find two consecutive odd integers such that 36 more than the lesser is three times the greater, set up an equation and solve for the variable x. The two consecutive odd integers are 15 and 17.

Explanation:

To find two consecutive odd integers such that 36 more than the lesser is three times the greater, we can set up an equation:

x + 36 = 3(x + 2)

Simplifying this equation, we get:

x + 36 = 3x + 6

Subtracting x from both sides, we get:

36 = 2x + 6

Subtracting 6 from both sides, we get:

30 = 2x

Dividing both sides by 2, we get:

15 = x

Therefore, the two consecutive odd integers are 15 and 17.

Suppose the population of a town is 15,200 and is growing 2% each year. Write an equation to model the population growth.

For this case, what you need to know is that to model this problem, you must use equations of the potential type:
 y = A * (b) ^ t
 Where:
 A: initial population.
 b: growth rate.
 t: time.
 Substituting values we have:
 y = 15200 * (1.02) ^ t

 y = 15200 * (1.02) ^ 10
 y = 18529

A 43


B 0


C 11


D 21

Answers

the answer wolud be 43                                                                                   good luck

Answer:

option: A is correct.

Step-by-step explanation:

We are asked to find the average number of pizzas sold in one night if no coupons are issued.

i.e. we have to find the value of y such that x=0 i.e. no coupon was issued.

We are given a equation which represents the linear model for this data:

y = 3.4x + 43

where y denotes the average number of pizza sold and x denotes the number of coupons issued.

Hence when x=0 we have value of y from the above linear equation as:

y=3.4×0+43=0+43=43

i.e. y=43.

Hence, average number of pizzas sold in one night if no coupons are issued are 43.

Step-by-step explanation:

To write f(x) = 2x^2 – 44x + 185, factor out from the first two terms.

Next, form a perfect square tri nomial keeping the value of the function equivalent: f(x) = 2(x^2 – 22x + 121) + 185 – 242

To get vertex form we factor x^2 -22x+121

product is 121 and sum is -22

-11*-11= 121 and sum -11+(-11)= -22

x^2 -22x+121

(x-11)(x-11)

f(x) = 2(x^2 – 22x + 121) + 185 – 242

f(x) = 2(x-11)(x-11)+ 185 – 242

f(x) = 2(x-11)^2 - 57
