A bag contains 1 red marble, 2 blue marbles, 3 yellow marbles, and 4 black marbles. A marble is randomly chosen from the bag, returned, and then another marble is chosen. What is the probablility that both marbles are blue?
Answer:
The probability that both marbles are blue is 1/25------------------------------------
Number of marbles:
Red = 1, blue = 2, yellow = 3, black = 4Total number:
1 + 2 + 3 + 4 = 10Probability of getting a blue marble:
P(blue) = number of blue / total numberP(blue) = 2/10 = 1/5Since the second marble is selected with replacement, the probability of the second blue marble is same, so the probability of two blue marbles is:
P(blue, blue) = 1/5*1/5 = 1/25[tex] \sf \: Probability _{(Blue)}=2/10×2/10 \\ \\ \sf Probability _{(Blue)}= \frac{1}{25} [/tex]

Answer:
23
Step-by-step explanation:
First of all we find the total number of students:
4+6+2+2+3+4+6+3=30
Then we find the amount of freshmen’s
4+3=7
Now we find the Fraction which represents the freshmen to all ratio:
[tex]\frac{7}{30}[/tex]
which is equal to:
0.2333...
Which can be converted into a percentage by multiplying it by 100
0.2333...×100=23.333...
Which is rounded down as the third digit, the 3, gets rounded down
so the answer is 23

tan( 4/3 + 12/5 )= what
Answer:
[tex]tan\frac{56}{15}[/tex]
Step-by-step explanation:
We are given the trigonometrical equation of tan( 4/3 + 12/5) and are asked to find the answer.
To solve this, keep in mind that even though this has tan, the process of adding fractions is no different from the original format.
First, find the LCM of 3 and 5, this would be 15. Multiply the numbers to get to 15 (3 and 5) by both denominators and numerators.
[tex]\frac{4*5}{3*5} + \frac{12*3}{5*3}[/tex]
[tex]\frac{20}{15}+\frac{36}{15}[/tex]
[tex]\frac{56}{15}[/tex]
Our answer would be [tex]tan\frac{56}{15}[/tex]
Answer:
tan(56/15)
Step-by-step explanation:
tan( 4/3 + 12/5 ) =
tan( 20/15 + 36/15) =
tan( 56/15 )
Find the perimeter of the shape
Answer:
54ft
Step-by-step explanation:
15- 8 = 7ft
12-5 = 7ft
7+7+12+15+5+8 = 54 ft
Answer:
15+12+8+7+7+5=54
Step-by-step explanation:
54
why 54?
there are two missing distances
so we see the two heights
12-5=7
and now the two lengths
15-8=7
now we got the missing lengths, and we add them
15+12+8+7+7+5=54
54 is the answer

14. A square has a perimeter of 36 units. One vertex of the square is located at (3,5) on the coordinate grid, What could be the x- and y-coordinates of another vertex of the square?
Answer:
For a square of side length L, the perimeter is:
P = 4*L
Then if the perimeter of our square is 36 units, we have:
36 units = 4*L
(36 units)/4 = L = 9 units.
Now we know that one vertex of the square is located at (3, 5)
Then another vertex of the square can be at:
A distance of 9 units of this point (such that these vertices are connected by one side of the square)
Some examples can be:
(3 + 9, 5) = (12, 5)
or
(3, 5 + 9) = (3, 14)
These are the simpler options, there are a lot of other possible points that can be another vertes (we can have a circle of radius 9 units centered in the point (3, 5), all these points can be another vertex of the square).
We also can have a vertex that is connected by the diagonal, this point can be:
(3 + 9, 5 + 9) = (12, 14)
or
(3 - 9, 5 - 9) = (-6, -4)
Again, there are a lot of other possible points that can be this vertex (A circle of radius √2*9 units centered in the point (3, 5)).

If enrollment in a class went from 30 people last term to 25 people this term, what is the percent decrease? Round to the nearest percent.
====================================================
Explanation:
The change in value is 30-25 = 5, so the amount has dropped by 5
Divide this change over the original amount to get 5/30 = 0.1667 approximately. This converts to 16.67% roughly, and that rounds to 17%
----------------
Here's a way to do it using a formula
A = old value = 30
B = new value = 25
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (25-30)/30 ] * 100%
C = -0.1667 * 100%
C = -16.67%
C = -17%
The negative percent change means we have a percent decrease. The class size went down by about 17%.

What is the difference between solving an equation and solving an inequality
Note that solving an equation involves finding the value(s) of the variable(s) that make the equation true. For example, solving the equation 2x + 3 = 7 would give the solution x = 2.
On the other hand, solving an inequality involves finding the set of all values of the variable(s) that make the inequality true. For example, solving the inequality 2x + 3 > 7 would give the solution x > 1.
What is inequality in Math?An inequality in mathematics is a relationship that makes a non-equal comparison between two integers or other mathematical expressions. It is most commonly used to compare the sizes of two numbers on a number line.
In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign.

the inaugural attendance of an annual film festival is 20,000. The attendance y increases by 5% each year
1. about how many people will attend the festival in the fifth year?
Answer:
24,241 people
Step-by-step explanation:
To determine the attendance at the festival in the fifth year, we need to calculate the cumulative increase in attendance over five years.
1st year: 20,000
2nd year: 20,000 * 1.05 = 21,000 (5% increase from the first year)
3rd year: 21,000 * 1.05 = 22,050 (5% increase from the second year)
4th year: 22,050 * 1.05 = 23,127.50 (5% increase from the third year)
5th year: 23,127.50 * 1.05 = 24,241.38 (5% increase from the fourth year)
So, in the fifth year the festival will be attended by approximately 24,241 people.

3 1/7 x [3 1/3 x (2/3+1/6) -1 5/18] ÷2 3/7 =?
Step-by-step explanation:
3 1/7 × [3 1/3 × (2/3 + 1/6) - 1 5/18] ÷ 2 3/7
well, first we have to bring everything to true fractions.
then we need to bring all fractions we need to add or subtract to the same denominators.
and then we simply calculate.
3 1/7 = (3×7 + 1)/7 = 22/7
3 1/3 = (3×3 + 1)/3 = 10/3
1 5/18 = (1×18 + 5)/18 = 23/18
2 3/7 = (2×7 + 3)/7 = 17/7
22/7 × [10/3 × (2/3 + 1/6) - 23/18] ÷ 17/7
to be able to add 2/3 and 1/6 we need to bring the to the same denominator, with its simply 6.
2/3 + 1/6 = 2/2 × 2/3 + 1/6 = 4/6 + 1/6 = 5/6
22/7 × [10/3 × 5/6 - 23/18] ÷ 17/7
22/7 × [50/18 - 23/18] ÷ 17/7
22/7 × 27/18 ÷ 17/7
22/7 × 27/18 × 7/17
22/17 × 27/18 = 22/17 × 3/2 = 66/34 = 33/17
so, the result is 33/17 = 1 16/17

On solving the provided question, we can say that - by formula of simple interest we have SI = [tex]2200 X 2 X 4/100 = > 17600/100 = > 176[/tex]
what is interest ?Multiplying the principal by the interest rate, time, and other factors yields simple interest. Simple return equals principle times interest times hours is the marketed formula. It is easiest to compute interest using this formula. A percentage of the principle balance is how interest is most commonly computed. For instance, he will only pay his portion of the 100% interest if he borrows $100 from a buddy and promises to pay it back with 5% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and when you lend money, you must charge interest. Most of the time, interest is expressed as a yearly percentage of the loan amount. The interest rate on the loan is known as this percentage.

principal, p = 2200
rate, r = 2%
time, t = 4 rs,
