5 3-digit numbers that have three equal digits.
we need to apply the principle of inclusion-exclusion to account for the fact that some 3-digit numbers may be counted multiple times.
any 3-digit number that has three equal digits will be counted twice once as a 3-digit number with two equal digits and one different digit, and once as a 3-digit number with three equal digits.
There are 5 choices for the digit that is repeated, and 1 way to arrange the digits, so there are 5 3-digit numbers that have three equal digits.
Therefore, we need to subtract 5 from the total number of 3-digit numbers that have two equal digits and one different digit.
60 number are 3-digit numbers that have two equal digits and one different digit.
What is permutation and combination?Permutation and combination are ways to arrange values in a set. In permutation the order of arrangement matters, but in combination the order of arrangement does not matter.
The given digits are,
1, 2, 3, 4, 5.
Since, to find the 3 digits numbers which are written by using given digits, and have two equal digits and one different digit,
Here order of arrangement matters.
Use permutation formula,
From 5 digits, 3 are chosen,
Ways of arrangement = ⁵P₃
= 5! / (5-3)!
= 5! / 2!
= 5 x 4 x 3 x 2! / 2!
= 60
There are total 60 different ways, in which numbers can be arranged.

At Outfield Sports Shop, Brandon is deciding which set of equipment to buy. He usually only plays with standard baseballs, but he wants to get some plastic baseballs to use when playing with his younger cousins. The store offers a starter set with 2 plastic balls and 5 standard balls, and a deluxe set with 4 plastic balls and 10 standard balls. Do the starter set and deluxe set have the same ratio of plastic baseballs to standard baseballs?
no links please
Answer:
Yes.
Step-by-step explanation: The Starter Set's ratio is 2:5 and the Deluxe set's ratio is 4:10. . You need to multiply the numerator and the denominator of the Starter Set by 2 and you will see that the ratio 2:5 is equivalent to ratio 4:10.
Two dams, when opened, release water at different rates. The following functions represent the amounts of water the dams release over t minutes:
Dam A
f(t) = 5t – 7t – 1
Dam B
g(t) = 3t 2 + 4t + 9
Which function represents the difference in the amounts of water released, h(t) = f(t) – g(t)?
h(t) = 3t 2 – 5t + 11t + 10
h(t) = 2t 2 – 11t – 10
h(t) = 5t – 3t 2 – 3t + 8

Answer:
If you use the area formula it should be really simple.
Step-by-step explanation:
Have you been taught base x height?
Answer:
To find the area, you use a specific formula for the shape.
For the squares and rectangles, multiply the length by the width.
For a triangle do base times height divided by 2.
I would suggest asking your teacher for help with the formula.

Using the box plot you drew for the following data set, describe how the data is dispersed: 22, 35, 18, 30, 37, 20, 40, 18, 38, 38, 23, 19, 27, 31, 34.
Answer:
The data is negatively skewed.
Step-by-step explanation:
When the median line is closer to the right side of the box plot, the data is negatively skewed. Another way to know is if the mean is less than the median; it looks like the median on your box plot is 30, and I calculated the mean of the data set to be 28.7.

A temperature of F degrees Fahrenheit is 5/9(F–32) degrees Celsius. According to weather records, the highest temperature ever recorded on the continent of Africa was 131 degrees Fahrenheit, in the country of Tunisia.
What was the highest temperature in degrees Celsius?
Answer:
131°F is 55°C!
Step-by-step explanation:
subtract 32 from 131, then multiply by .5556 (5/9)
131 - 32 = 99
99 × 5/9 = 55

[tex]\frac{3}{4}[/tex] t = -9 what does t equal?
Answer:
t=-12
Step-by-step explanation:
3/4(t)=-9
divide by 3/4 on both sides, and when you divide by a fraction, you actually multiply the reciprocal of the fraction instead of trying to somehow divide.
Soooooo... the reciprocal of 3/4 is 4/3, right?
t= -9 * 4/3
t=-12

Let me explain it in an understanding matter
To find average we need to add the 2 numbers then divide by the amount of numbers there is which is 2.
So the first step is to add 2 3/5 and 87 1/10
The answer to that is 89 7/10
Lastly we need to divide 89 7/10 by 2
The answer to that is 44 17/20
So your answer should be 44 17/20

Angle PQR and angle TQV are vertical angles. The measures of the two angles have a sum of 100o. Write and solve an equation to find x, the measures of angle TQV.
Answer:
I'm not certain what the sum is, so I will teach you how to solve.
Step-by-step explanation:
As the question states, angle PQR and TQV are vertical angles, so they have to be the same measure. Just divide the sum by 2 and you get the answer.
If there were more context, I would totally edit my answer!

The formula for the area of a circle is A=π×r^2.
Step 1: Find r, or the radius, which is half the diameter. In this case, it is 8.95.
Step 2: Square the radius that you get. In this case, the answer is 80.1025.
Step 3: Multiply the past number by π on your calculator. Some teachers allow 3.14 but be certain that your teacher allows it. In this case, π×80.1025=251.649425534
Step 4: You've got your answer! Hope this helps!
