Choosing a green jelly bean.
Spinning a number less than 2 on a spinner.
Choosing a spade out of a standard deck of cards.
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
Probability of choosing a green jelly bean = number of green jelly bean / total number of beans
2/8 x 100 = 25%
Probability of spinning a number less than 2 on a spinner = number that is less than 2 / total number of sections
1/4 x 100 = 25%
Probability of choosing a choosing a spade= number of spade / total cards in the deck
13/54 x 100 = 25%

The three options that have a probability of 25 percent are:
- Choosing a green jelly bean
- Spinning a number less than 2 on a spinner
- Choosing a spade from a standard deck of cards
The probability of an event occurring is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. A probability of 25 percent corresponds to a ratio of 1 out of 4 (since 25% is one-fourth of 100%). Let's analyze the options:
1. Choosing a green jelly bean: There are 2 green jelly beans out of a total of 2 + 1 + 5 = 8 jelly beans. The probability is 2/8, which simplifies to 1/4 or 25%. This option has a probability of 25%.
2. Rolling a number less than 3 on a six-sided die: There are 2 favorable outcomes (1 and 2) out of 6 possible outcomes (1 through 6). The probability is 2/6, which simplifies to 1/3 or approximately 33.33%. This option does not have a probability of 25%.
3. Spinning a number less than 2 on a spinner: There is 1 favorable outcome (1) out of 4 possible outcomes (1 through 4). The probability is 1/4 or 25%. This option has a probability of 25%.
4. Choosing an Oregon state quarter: There are 3 Oregon state quarters out of a total of 4 + 3 + 6 + 3 = 16 state quarters. The probability is 3/16, which is not equal to 25%.
5. Choosing a spade from a standard deck of cards: There are 13 spades out of a total of 13 + 13 + 13 + 13 = 52 cards. The probability is 13/52, which simplifies to 1/4 or 25%. This option has a probability of 25%.

Using continuity concepts, it is found that the function is left-continuous at x = 1.
-------------------------------
A function f(x) is said to be continuous at x = a if:
-------------------------------
The piece-wise definition of the function is:
We have to check the continuity at the points in which the definitions change, that is, x = 0 and x = 1.
-------------------------------
At x = 0:
Since the limits are equal, and also equal to the definition at the point, the function is continuous at x = 0.
-------------------------------
At x = 1:
To the right, the limit is different, thus, the function is only left continuous at x = 1.
A similar problem is given at brainly.com/question/21447009
Answer:
the function is continuous from the left at x=1 and continuous from the right at x=0
Step-by-step explanation:
a function is continuous from the right , when
when x→a⁺ lim f(x)=f(a)
and from the left when
when x→a⁻ lim f(x)=f(a)
then since the functions presented are continuous , we have to look for discontinuities only when the functions change
for x=0
when x→0⁺ lim f(x)=lim e^x = e^0 = 1
when x→0⁻ lim f(x)=lim (x+4) = (0+4) = 4
then since f(0) = e^0=1 , the function is continuous from the right at x=0
for x=1
when x→1⁺ lim f(x)=lim (8-x) = (8-0) = 8
when x→1⁻ lim f(x)=lim e^x = e^1 = e
then since f(1) = e^1=e , the function is continuous from the left at x=1

Answer:
Part 1= Pi * R Squared
Part 2: 50.27
Part 3: 78.54
Part 4: 28.27
Step-by-step explanation:
Part 1: Memorize the formula
Part 2: 8 feet diameter = Pi * 4 squared. 8 feet is the diameter so the radius is 4. 4 squared is 16. 16 * pi = approximately 50.27, but is 50.24 if 3.14 is used as pi.
Part 3: Pi * 5 squared since 10 is diameter. 25 * pi which is close to 78.54, but is 78.5 is 3.14 is used for pi.
Part 4: I subtracted Part 3 from Part 2.
Answer:
Th best thing would be 35% off or the blue coupon
Step-by-step explanation:
Well we can solve the orange coupon first which would be 540.37 for the final price
the blue coupon is 35 percent off or we can just multiply 815.37 by 0.65 becuase since its “off” you would only have to pay 65 percent of the item which is why I’m multiplying by 0.65. You would end up with something like 529 something which is less than 540.37
The blue coupon would be best
Also why not use both of them?
_ pounds of sugar candies
=OWO=
Answer: 9 pounds of chocolate and 6 pounds of sugar candies
Let's define the variables:
C = pounds of chocolate candies used.
S = pounds of sugar candies used.
We know that he wants to make a total of 15lb, then:
C + S = 15
We also want that the price per pound to be equal to 5$.
This means that the price of the 15 pounds will be the same as the price of the un-mixed candies.
C*$7.00 + $2.00*S = $5.00*15
Then we have a system of equations:
C + S = 15
C*$7.00 + $2.00*S = $5.00*15
To solve this system, we need to start by isolating one of the variables, i will isolate C in the first equation:
C = 15 - S
now we can replace that in the other equation:
(15 - S)*$7.00 + $2.00*S = $5.00*15
Now we can solve this for S.
$105 - $5.00*S = $75
$105 - $75 = $5.00*S
$30 = $5.00*S
$30/$5 = S = 6
Then there are 6 pounds of sugar candy, and we can use the equation:
C + S = 15
C + 6 = 15
C = 15 - 6 = 9
There are 9 pounds of chocolate candy in the mix.
Step-by-step explanation:
To find the pounds of chocolate and sugar candies the owner should use, set up and solve equations based on the given information.
Let's assume that the owner uses x pounds of chocolate candies and y pounds of sugar candies.
According to the problem, the total weight of the candies should be 15 pounds.
So, we can set up the equation:
The owner wants to sell the candies for $5.00 per pound. We can set up another equation to represent the total value of the candies:
Now we can solve these equations to find the values of x and y.
By solving the equations, we find that x = 9 and y = 6.
Therefore, the owner should use 9 pounds of chocolate candies and 6 pounds of sugar candies.
