The probability that the flashlight will be either blue or black is,
⇒ 20/30
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.
We have to given that;
A box contains 18 blue flashlights, 3 red flashlights, 7 silver flashlights, and 2 black flashlights.
Hence, Total number of flashlights are,
⇒ 18 + 3 + 7 + 2
⇒ 30
So, the probability that the flashlight will be blue is,
⇒ 18 / 30
And, the probability that the flashlight will be black is,
⇒ 2 / 30
Hence, the probability that the flashlight will be either blue or black is,
⇒ 18/30 + 2/30
⇒ 20/30

The probability of flashlight to be black or blue is 2/3. To find the probability of selecting a blue or black flashlight from a box, add the number of blue and black flashlights, then divide by the total number of flashlights.
We first find the total number of blue and black flashlights, which is 18 (blue) + 2 (black) = 20.
Then, we divide this by the total number of flashlights in the box (18 + 3 + 7 + 2 = 30) to get the probability.
The probability of choosing a blue or black flashlight is 20/30 = 2/3 = 0.67.

What is the y-intercept of the parabola, y=25/4x^2+10x?
Answer:
0
Step-by-step explanation:
To get the y-intercept ,all you have to do is to substitute x by 0 in the equation y=25/4x²+10x and find the value of y .
y = 25/4(0)²+10(0)
= 0 + 0

Algebraic fractions cannot be reduced.
True
False
Final answer:
Algebraic fractions can be reduced by finding the greatest common factor (GCF) and simplifying the fraction to its lowest terms.
Explanation:
False. Algebraic fractions can be reduced. To reduce an algebraic fraction, you need to find the greatest common factor (GCF) of the numerator and denominator, and then divide both the numerator and denominator by the GCF. This simplifies the fraction to its lowest terms. For example, if you have the fraction (2x + 4)/(6x + 12), the GCF of the numerator and denominator is 2, so you can simplify the fraction to (x + 2)/(3x + 6).

Find an explicit formula for the geometric sequence 120, 60, 30, 15, ...
Final answer:
The explicit formula for the geometric sequence 120, 60, 30, 15, ... is an n = 120 times [tex](0.5)^{n-1}[/tex], where an is the nth term of the sequence.
Explanation:
The sequence given, 120, 60, 30, 15,..., is an example of a geometric sequence where each term is obtained by multiplying the previous one by a constant called the common ratio. For this sequence, the first term a is 120, and the common ratio r is 0.5 since each term is half the preceding one.
An explicit formula for a geometric sequence can be expressed as:
an = a times [tex]r^{n-1}[/tex]
Where a is the first term, r is the common ratio, and n is the term number. Applying this to the given sequence, the explicit formula is:
an = 120 times [tex](0.5)^{n-1}[/tex]
This formula represents the nth term of the sequence, showing how each term can be calculated directly from its position in the sequence.

A family of 20 purchased tickets to the county fair. Tickets for adults cost $8 while tickets for children cost $4. If the total cost of tickets were $100, how many family members were adults and children? Explain how you solved the problem
Answer:
There are 5 adults and 15 children in the family.
Step-by-step explanation:
Given
Number of people in the family = 20
Cost of adults tickets = $8
Cost of children tickets = $4
Total ticket sold = $100
Required
How many adults and children are in the family.
Let C represent children and A represent adults.
If there are 20 members of the family, then.
A + C = 20
Also, if adult tickets is sold for $8 and children tickets is sold for $4 and the total cost of tickets were $100, then we have
8A + 4C = 100.
Now, we have two equations to be solved simultaneously.
A + C = 20 --- (1)
8A + 4C = 100 ---- (2)
Make C the subject of formula in (1)
C = 20 - A.
Substituton 20 - A for C in (2)
8A + 4(20 - A) = 100
8A + 80 - 4A = 100
Collect like terms
8A - 4A = 100 - 80
4A = 20
Multiply both sides by ¼
¼ * 4A = ¼ * 20
A = 5
Recall that C = 20 - A
So,
C ,= 20 - 5
C = 15.
Hence, there are 5 adults and 15 children in the family.
The Question was solved by getting an expression to represent the amount of tickets that were sold and another expression for the total number of people in the family.
The two expressions gave us a simultaneous equation and the equations were solved simultaneously.

Jessie is considering a purchase of a $135,000 home at 5.5%. Under this rate,
her mortgage payment would be $766.51. If she purchases a point, her new
mortgage payment is $755.96. How many months would it take her to break-
even on the points purchase?
A. 244 months
B. 186 months
C. 128 months
D. 134 months
Answer: 128 months
Step-by-step explanation:
Final answer:
Jessie will break even on the point purchase for her mortgage in approximately 128 months, as a point costs 1% of the $135,000 home, and the monthly mortgage payment falls by $10.55 after purchasing the point.
Explanation:
The student is asking how many months it will take Jessie to break even on the purchase of a point for her mortgage. A point typically costs 1% of the loan amount, and in return, the lender reduces the interest rate on the mortgage. In this case, the monthly payment is reduced from $766.51 to $755.96, a monthly savings of $10.55 ($766.51 - $755.96).
To calculate the break-even point in months, divide the cost of the point by the monthly savings. If a point costs 1% of the $135,000 home, then the cost is $1,350 ($135,000 * 0.01). The number of months to break even is therefore $1,350 / $10.55, which equals approximately 128 months.
Therefore, the correct answer would be:
C. 128 months

what is the measurement of each angle?
Answer:
87°, 68°, and 25°
Step-by-step explanation:
All the angles in a triangle will equal to 180° so with knowing this you can create the equation...
(7x-11)° + (2x-3)° + (5x-2)° = 180°
(14x-16)° = 180°
14x = 180° + 16°
14x = 196°
x = 14°
Knowing x you can substitute this value into each angle.
7(14)-11 = 87°
5(14)-2 = 68°
2(14)-3 = 25°
To confirm that these are the right answers you can add all these angles to see if they equal to 180°.
87° + 68° + 25° = 180°
Answer:
7x -11 = 87 degree
5x-2 = 68 degree
2x-3 = 25 degree
When you turn this triangle into a parallelogram, we remember the opposite angles add up to 180 so we label top or bottom corner angle label it x/2 in this diagram as 7x is higher we label this one x/2 instead to make a parallelogram make sense to the triangles, being the ratio angles of each 4 corners.
We then know that that triangle within other angles at the bottom are smaller as they share another angle where top missing quadrilateral angle shares the left bottom supplementary angles as 2 opposite ends on a parallelogram add up to 180 degree.
We do the sums and call x 14 start with the top angle first
7x -11 = 7(14) -11 = 98-11 = 87 degree
5x-2 = 5(14)-2 = 68 degree
2x-3 = 2 (14) -3 = 25 degree
If you do this again for different measures and find the bottom angle is higher then you just redo your workings as bottom first is higher and find why with x.
To show your ways of reasoning that all x = 14 etc.
x= 14

The given sine value of 2/1 is not possible as the sine of an angle cannot exceed 1 or be less than -1. It seems there's an error in your question and incomplete information prevents a comprehensive answer.
Explanation:Given that the sin 8 = 2/1, it's important to note that in a range of -1 and 1, the sine of an angle cannot be greater than 1 or less than -1. Therefore, there's an error in your original question. Also, the second part of your question seems to be cut off (gº C. 1 IN NI).

Kyle is a basketball player. His bottle was full at the beginning of the game. At the end of the first quarter, he drank 5/7 of the bottle. A coach filled up his bottle for him during the second quarter. At the end of second quarter, he drank some more water and left only 2/5 of water in the bottle. How much water did he drink during the first half of the game?
Final answer:
Kyle drank a total of 39/35 liter of water during the first half of the game.
Explanation:
To find the amount of water Kyle drank during the first half of the game, we need to calculate the difference between the initial amount of water and the amount left at the end of the second quarter.
Let's assume Kyle's bottle initially held 1 liter of water.
At the end of the first quarter, he drank 5/7 of the bottle or (5/7) * 1 = 5/7 liter of water.
After the coach filled up his bottle during the second quarter, the bottle was full again.
At the end of the second quarter, he drank some more water and left only 2/5 of water in the bottle, which is (2/5) * 1 = 2/5 liter of water.
Therefore, Kyle drank a total of 5/7 + 2/5 = 25/35 + 14/35 = 39/35 liter of water during the first half of the game.
