You pick a card at random, put it back, and then pick another card at random.
2 3 4 5
What is the probability of picking a number greater than 3 and then picking a 5?
Answers
Answer:
12.5%
Step-by-step explanation:
out of the 4 cards only two are >3 (4 and 5)
so 2/4 on the first choice (simplified to 1/2)
picking a 5 is 1/4 since there is only one 5
since they are happening at the same time multiply the two probabilities
1/2*1/4
=1/8
=0.125
=12.5%

You are given a triangle with side lengths of 6, 9, and 12. Is the triangle a right triangle? How do you know?
Answers
Answer:
No, it's not
Step-by-step explanation:
You choose the longest side which is 12 and apply the theory of phitagors
The longest side which is the hypotenuse in a right triangle = square root the square sum for each side
So to be a right triangle it should be
\( \sqrt{ {9}^{2} + {6}^{2} } = 10.8 \: \: that \: doesnt \: equal \: 12\)
So it's not a right triangle.
Look at the famous right triangle whose side are 5(hypotenuse), 4, 3
\( \sqrt{ {4}^{2} + {3}^{2} } = 5\)
So it's a right triangle
Right triangle lengths can be checked by the Pythagorean theorem.
This states that a^2+b^2=c^2
a and b are the shorter side lengths, and they form the right angle. c is the hypotenuse, and is the longest length.
Input the values to check if the equation checks out:
6^2+9^2=12^2
36+81=144
117≠144
No, it is not a right triangle. Hope this helps!

Madison has a bag that contains strawberry chews, lemon chews, and lime chews. She performs an experiment. Madison randomly removes a chew from the bag, records the result, and returns the chew to the bag. Madison performs the experiment 26 times. The results are shown below: A strawberry chew was selected 10 times. A lemon chew was selected 14 times. A lime chew was selected 2 times. Based on these results, express the probability that the next chew Madison removes from the bag will be a flavor other than lemon as a percent to the nearest whole number.
Answers
Answer: 46% possibility
the value of probability of the next chew Madison removes from the bag being a flavor other than lime is,
⇒ 12/13.
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one
Now, the probability of the next chew being a flavor other than lime,
Here, The total number of chews used in the experiment is:
10 (strawberry) + 14 (lemon) + 2 (lime) = 26
Since, Madison returns the chew to the bag after each experiment, the total number of chews in the bag remains the same.
Therefore, the probability of selecting a flavor other than lime on the next experiment is:
= (10 strawberry chews + 14 lemon chews) / 26 chews
= 24/26
= 12/13
Therefore, the probability of the next chew Madison removes from the bag being a flavor other than lime is 12/13.

Answer:
\(Accept = 69.44\%\)
\(Reject = 11\)
Step-by-step explanation:
Given
See attachment for dataset
Solving (a): Percentage to accept
The percentage to accept are flea collars that range between 14mg to 16mg (inclusive)
From the attachment, we have:
\(Total = 36\)
\(n(14mg-16mg) =25\) --- Number of 14mg to 16mg
So, the percentage to accept is:
\(Accept = \frac{n(14mg-16mg)}{Total} * 100\%\)
\(Accept = \frac{25}{36} * 100\%\)
\(Accept = 0.6944 * 100\%\)
\(Accept = 69.44\%\)
Solving (b): Collars to reject
In (a), we have:
\(n(14mg-16mg) =25\)
The number to reject is then calculated by subtracting the collars to accept from the total (this is called complement rule)
So, we have:
\(Reject = Total - n(14mg - 16mg)\)
\(Reject = 36 - 25\)
\(Reject = 11\)
11 will be rejected

A notebook is 3/10 off the original price. How could this be written as a decimal? What percentage is the discount?
Answers
Answer:
A decimal: 0.3 A percentage: 30%
Step-by-step explanation:
To calculate the decimal:
3/10=0.3
Three divided by 10 is 0.
After writing the zero put a little dot beside it.
Then you add a little zero to three to make it 30
Then it becomes 30 divided by 10 and the answer is three so the decimal is 0.3
To calculate the percentage:
You can use the decimal. So we say 0.3 multiplied by 100 because a percentage is out of 100.
The answer is 30%

3x + 45-45 = 90 -45
3x = 45
Divide both sides by 3
3x/3 = 45/3
x = 15
#20 supplementary
2x + 3x + 25 = 180
5x + 25 = 180
5x + 25 - 25 = 180 -25
5x = 155
Divide both sides by 5
5x/5 = 155/5
x = 31
#15 - vertical
4x - 25 = 75
4x - 25 + 25 = 75 + 25
4x = 100
Divide both sides by 4

x = 25

In 56 years, Kevin will be 9 times as old as he is now

Answers
Answer:
correct answer is 7 years
Step-by-step explanation:
A+56=9(A)
56+9A
A=7
he will be 7 years old he is pretty old
Answer:
Kevin is 7 years old right now.
Step-by-step explanation:
Let x be Kevin's age right now, that's what we're trying to find.
In 56 years, he'll be 9 times older than he is now, so we can say:
x + 56 = 9x
Now we can get the x values on the right side of the equation so that:
56 = 8x
Now solve for x and you have his current age which is 7.
