49.5 is what percent of 30?
Answer:
165 %
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 30 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 30, so we can write it down as 100%=30.
4. We know, that x% equals 49.5 of the output value, so we can write it down as x%=49.5.
5. Now we have two simple equations:
1) 100%=30
2) x%=49.5
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=30/49.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 49.5 is what percent of 30
100%/x%=30/49.5
(100/x)*x=(30/49.5)*x - we multiply both sides of the equation by x
100=0.60606060606061*x - we divide both sides of the equation by (0.60606060606061) to get x
100/0.60606060606061=x
165=x
x=165
now we have:
49.5 is 165% of 30

A bag contains 5 balls: 3 blue, 1 red, and 1 yellow. You select a ball at random 4 times, replacing the ball after each selection. Calculate the theoretical probability of getting a blue ball exactly 3 times
Answer:
[tex] P(X=3)[/tex]
And replacing we got:
[tex]P(X=3)=(4C3)(0.3)^3 (1-0.3)^{4-3}=0.0756[/tex]
Step-by-step explanation:
Let X the random variable of interest "number of times that we select a blue ball", on this case we now that:
[tex]X \sim Binom(n=4, p=3/10)[/tex]
The probability is always the same since we replace the ball selected in each trial.
The probability mass function for the Binomial distribution is given as:
[tex]P(X)=(nCx)(p)^x (1-p)^{n-x}[/tex]
Where (nCx) means combinatory and it's given by this formula:
[tex]nCx=\frac{n!}{(n-x)! x!}[/tex]
And we want to find this probability:
[tex] P(X=3)[/tex]
And replacing we got:
[tex]P(X=3)=(4C3)(0.3)^3 (1-0.3)^{4-3}=0.0756[/tex]
A hat contains 5 balls. The balls are numbered 1, 2, 4, 7, and 8. One ball is randomly selected and not replaced, and then a second ball is selected. The numbers on the 2 balls are added together. A fair decision is to be made about which one of two restaurants to eat at, using the sum of the numbers on the balls.
The restaurant options are Joe's Place or Taco Towne.
Which description accurately explains how a fair decision can be made in this situation?
a) If the sum of the balls is a factor of 30, eat at Joe's Place. If the sum is not a factor of 30, eat at Taco Towne.
b) If the sum of the balls is less than 10, eat at Joe's Place. If the sum of the balls is 10 or more, eat at Taco Towne.
c) If the sum of the balls is even, eat at Joe's Place. If the sum of the balls is odd, eat at Taco Towne.
d) If the sum of the balls is a multiple of 3, eat at Joe's Place. If the sum is not a multiple of 3, eat at Taco Towne.
Answer:
a) If the sum of the balls is a factor of 30, eat at Joe's Place. If the sum is not a factor of 30, eat at Taco Towne.
Step-by-step explanation:
The sum table can be represented as :
1 2 4 7 8
1 X 3 5 8 9
2 3 X 6 9 10
4 5 6 X 11 12
7 8 9 11 X 15
8 9 10 12 15 X
The Probability sum is a factor of 30 = P(sum is 3, 5, 6, 10, 15)
= [tex]\dfrac{2}{20} +\dfrac{2}{20}+\dfrac{2}{20}+\dfrac{2}{20}+\dfrac{2}{20}[/tex]
= [tex]\dfrac{10}{20}[/tex]
= [tex]\dfrac{1}{2}[/tex]
The Probability sum less than 10 = P(sum is 3,5,8,9,6)
= [tex]\dfrac{2+2+2+4+2}{20}[/tex]
= [tex]\dfrac{3}{5}[/tex]
The probability sum is even = P( sum is 6,8,10, 12)
= [tex]\dfrac{2+2+2+2}{20}[/tex]
= [tex]\dfrac{8}{20}[/tex]
= [tex]\dfrac{2}{5}[/tex]
The probability sum is a multiple of 3 = P( sum is 3,6,9,12,15)
= [tex]\dfrac{12}{20}[/tex]
= [tex]\dfrac{3}{5}[/tex]
since the probability that is the sum of the ball is a factor of 30 is [tex]\dfrac{1}{2}[/tex] , Thus, the probability that the sum is not a factor of 30 will also be [tex]\dfrac{1}{2}[/tex] . Thus; the description that accurately explains how a fair decision can be made in this situation is option A.
a) If the sum of the balls is a factor of 30, eat at Joe's Place. If the sum is not a factor of 30, eat at Taco Towne.

First, you'd work out the centre value
It would be the opposite value to what is in the brackets
Thus, the centre value is (2, -4)
Plot this value on a graph
In order to find the radius, you must square root the 25
Thus, the radius would be 5
Plot some points with a radius of 5 from the centre and then draw the circle

Describe how to regroup to solve the subtraction problem below what is the difference 456-238
Answer:
218
Step-by-step explanation:
456 - 238 =
Borrow 1 from 5 so number is 4 4 16 - 238=
16-8 = 8 in ones' place
4 - 3 = 1 in tens' place
4 - 2 = 2 in hundreds' place
The difference between 456 and 238 is 218.
To regroup and solve the subtraction problem 456 - 238, you can follow these steps:
1. Begin by writing down the two numbers vertically, with the larger number (456) on top and the smaller number (238) below it:
456
- 238
2. Start by subtracting the ones (or units) column.
Since 6 is larger than 8, you need to regroup.
Borrow 1 ten from the tens column of 5. This will make the 5 in the tens column become 4, and you add the borrowed ten to the ones column. So, the subtraction becomes 16 - 8, which equals 8:
456
- 238
-------
8
3. Next, move to the tens column.
Subtract 4 (the regrouped value) from 5, which equals 1:
456
- 238
-------
1 8
4. Finally, subtract the hundreds column. Subtract 2 from 4, which equals 2:
456
- 238
-------
2 1 8
Therefore, the difference between 456 and 238 is 218.

Slips of paper are numbered 1 through 10. If one slip is drawn and replaced 40 times, how many times should the slip with number 10 appear?
Hey there!
We have 10 pieces of paper. The probability of drawing a 10 is 1/10. Therefore, if we were to draw ten times, the ten should probably be drawn once. If we multiplied our number of drawings by four (10*4=40), our outcome of seeing our slip with the ten should also quadruple and become four times. (1*4=4)

Television sizes are labeled by the measure of the diagonal. What size is the TV below?
Answer:
55 inches.
Step-by-step explanation:
So, in the question above we are given the following data or parameters or information which will assist us in solving this kind of question efficiently. Here are the information needed below;
(1). "Television sizes are labeled by the measure of the diagonal.''
(2). "47.5 inches up top and the side is 27 inches" which are the length and the breadth respectively. Therefore, we will make use of the formula below In solving this question;
Size of the Television = √[(Length of the Television)^2 × (breadth of the television)^2].
Hence, the size of the Television = √( 47.5)^2 + (27)^2. = 54.63744137494.
Approximately:
The Size of the Television = 55 inches.
Mercury is 36 million miles
way from the sun. Venus
672 million miles from
the sun what is the
difference in distance
Answer:
636 million miles.
Step-by-step explanation:
672 minus 36 is 636. (Because they're both in the millions, you can just subtract their face values).
Since they have the same term (million) we simply subtract 672 and 36, then add million to the answer. 636 million miles is the difference in distance.

Answer: x=-14
Step-by-step explanation:
If the line is perpendicular to the x-axis, that means it is parallel to the y-axis. All lines that are parallel to the y-axis have the form x=. Since we know the line passes through the x value of -14, that means the equation of the line is x=-14.

20 ft
82.8 ft.
31.4 ft.
51.4 ft
62.8 ft.
Step-by-step explanation:
Hello there, because you did not attached the photo or the information of the diameter of the circle, so I will solve this type of question under a general form
Let's assume d is the diameter of the circle
=> the perimeter of the circle is: dπ
=> the perimeter of the half arc of a circle
= 1/2 perimeter of the circle
= 1/2dπ
Hence, the perimeter of the stage shaped like a semi-circle:
= the perimeter of the half arc of a circle + the diameter
= 1/2dπ + d
= 3/2dπ
Just substitute d into the above expression, you will find out the answer.

7.987 ot the tenths place
Answer:
If your were rounding 7.987 to the tenths place, you would get 8.
To round to the tenths place, you are trying to make the number enda tthe tenths place.
You are rounding the 9 in the tenths place, so look at the hundredths place. Since 8 is larger than 5, round the 9 up to 10.
We can't write 7.10 because that is a different number, so add the 1 to the 7 to get 8.
The final answer would be 8.0 or just 8.
