Answer:
The equation a + d(n-1)
Step-by-step explanation:
Where a is the first number in the sequence, d is the common difference and n is the position of a certain number in the series, e.g
1, 2, 3, 4, 5: a = 1, d = 1 (because 2-1=1, 3-2=1, 4-3=1, etc) and n = 1,2,3...
2, 4, 6, 8, 10: a = 2, d = 2 (because 4-2=2, 6-4=2, etc) and n = 1,2,3,4,5...
So for the second sequence, we could try to get the value of n in n = 6 as follows:
a + d(n-1) where a = 2, n = 6 and d = 2
Thus, 2 + 2(6-1) = 2 + 2(5) = 2 + 10 = 12
So the sixth number in the series would be 12

An apartment has two closets. Closet #1 is 4 feet long and 5 feet deep; Closet #2 is 6 feet long and 3 feet deep. Both closets are 8 feet tall. Which closet is larger?
Answer:
Closet #1.
Step-by-step explanation:
Closet #1 is 4x5x8, right? so, 4x5=20, and 20x8=160 feet. Closet #2 is 6x3x8, and 6x3 is 18. That's already less than 20 even before we multiply by 8. So, the answer to your question is Closet #1.
Answer:
Answer: The first closet is larger.
Step-by-step explanation:
Closet #1
V = l × w × h
V = 4 ft. × 5 ft. × 8 ft.
V = 160 cu. ft.
Closet #2
V = l × w × h
V = 6 ft. × 3 ft. × 8 ft.
V = 144 cu. ft.
Compare the size of the closets
160 cu. ft. > 144 cu. ft.
Answer: The first closet is larger.

Answer:
1. N, 2. S, 3. S, 4. S, 5. N*
Step-by-step explanation:
By "similar," I'm assuming you mean the same thing as "like" terms. Those are exactly the same (same variables and same exponents) but could have different coefficients (the number in front).
1. N variables are not the same
2. S variables are the same, exponents are the same
3. S same variables; same exponents (x^3 y^2 is the same as y^2 x^3)
4. S
5. N first term has z^2 in it; the second does not

suppose the probability you will get an A in this class is .25 and the probability you will get a B is .50. What is the probability your grade will be above a C?
Answer:
75% chance
Step-by-step explanation:
Probability always adds to 1.00
Letter grades are always in the form A, B, C, D...
The grades above a C are A, which is a 25% chance and B, which has a 50% chance. Adding these up we get a 75% chance.
#LearnWithBrainly
The probability of getting a grade above a C is 0.75, or 75%.
We have,
To calculate the probability of getting a grade above a C, you need to add the probabilities of getting an A or a B.
Given:
Probability of getting an A (P(A)) = 0.25
Probability of getting a B (P(B)) = 0.50
A grade above a C includes grades of A and B.
Therefore, the probability of getting a grade above a C (P(above C)) is:
P(above C) = P(A) + P(B)
P(above C) = 0.25 + 0.50
P(above C) = 0.75
Thus,
The probability of getting a grade above a C is 0.75, or 75%.

The middle of the upper half of a set of organized data is called the upper quarter.
How is called the middle of the upper half?We can divide the organized data in two halfs or in 4 quartiles (the interquartile range), where each quartile contains 25% of the data.
Such that each of the two halfs would be divided into two quartiles.
The middle of the upper half (where the third quartile ends and the fourth starts) is called the upper quarter.

Which of the following is the best first step to convert the following equation to slope
intercept form?
2-4y =-12
Answer: y=7/2 in decimal form 3.500
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2-4*y-(-12)=0
Pull out like factors :
14 - 4y = -2 • (2y - 7)
Solve : 2y-7 = 0
Add 7 to both sides of the equation :
2y = 7
Divide both sides of the equation by 2:
y = 7/2 = 3.500

-2b+2(b-10)=2(10+5b)
Answer:
b= -4
Step-by-step explanation:
On both sides of the equation has distributive property. We need to solve that first. Let's start with the left side of the equation.
*Positive multiplied by a negative equals a negative
-2b+2(b-10)= 2(10+5b)
-2b+2b-20= 2(10+5b)
-20= 2(10+5b)
Now let's solve the right side of the equation
-20= 20+10b
-20 -20
-40 = 10b
-40/10 = 10b/10
b= -4

Step-by-step explanation:
a) Tangent equals sine divided by cosine. Therefore:
tan(-t) = sin(-t) / cos(-t)
b) Using the fact that sin(-t) = -sin(t) and cos(-t) = cos(t):
tan(-t) = -sin(t) / cos(t)
tan(-t) = -tan(t)
c) A function is symmetric about the origin if f(-x) = -f(x) (in other words, if it's an odd function). Therefore, y = tan(t) is symmetric about the origin.
