[tex]a_n=-2-5n[/tex]
Step-by-step explanation:
Arithmetic Sequences
The arithmetic sequences are those where any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
[tex]a_n=a_1+(n-1)r[/tex]
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
We are given the sequence
-7 -12 -17 -22 -27 ...
The first term of this sequence is a1=-7. We can calculate the common difference by subtracting two consecutive terms:
r = -12 - (-7) = -12 + 7 = -5
The nth term is:
[tex]a_n=-7+(n-1)(-5)[/tex]
Multiplying:
[tex]a_n=-7-5n+5[/tex]
Simplifying:
[tex]\boxed{a_n=-2-5n}[/tex]
Suppose that 32% of people have a dog, 28% of people have a cat, and 23% of people own both.
What is the probability that someone owns a dog or a cat?
Answer:
37%
Step-by-step explanation:
Use the general addition rule for any two events:
(32 + 28) - 23
60 - 23
= 37
So, the probability that someone has a dog or cat is 37%
Answer:
37%
Step-by-step explanation:
32 + 28 = 60
60 - 23 = 37

Answer:
The 6x6 cube is 1/4 the area of the 12x12 cube.
100%=$1,636,364 (Rounded to the dollar)
Step-by-step explanation:
6x6=36
12x12=144
36/144=1/4
_____________________
20%=?
25%=?
Remainder (55%=$900,000) so:
100%=$900,000/.55
100%=$1,636,364

Myka bought a shirt that was originally priced at $40 and on sale for $34. What was the percent discount?
Lori needs more than 250 signatures to run for the position of class president for her middle school. She already has 75 signatures and believes that she can get 25 more signatures each day. She wants to figure out how many days, d, she should collect the signatures she needs. Which inequality and solution for d correctly represent Lori’s situation?
Answer:
75 + 25d > 250
d > 7
Step-by-step explanation:
Number of signatures needed : > 250
Amount of signatures ready = 75
Exoected number of signatures per day = 25
Number of days, d, needed signatures will be collected ;
Number of ready signatures + (expected number of signatures per day * number of days) > number of signatures needed
Mathematically,
75 + 25d > 250
25d > 250 - 75
25d > 175
d > 175 / 25
d > 7

Is the same as:
___· ___ = -48
A positive number multiplied by a negative number has a negative product.
P * N = N
Two positive numbers and two negative numbers have a positive product.
P * P = P
N * N = P
6 and -8 and -6 and 8 would be the correct answers. Again, a positive and a negative number will have a negative product.
6 * -8 = -48
-6 * 8 = -48

I used a calculator
Ben is n years old.
Chloe is twice as old as Ben.
Dan is five years younger than Ben.
The total of Ben’s age, Chloe’s age and Dan’s age is T years.
(a) Find a formula for T in terms of n.
Answer:
T = 4x - 5
Step-by-step explanation:
Let x = Ben's age
2x = Chloe's age
x - 5 = Dan's age
Combine all the terms and simplify to form an equation.
T = 2x + x + x -5
T = 4x - 5

Someone help will give you 5star and brainliest
Answer:
We know that if
y ∝ x²
∴ y = k · x²
Now
y = 8 , x = 4
From above y = k · x²
⇒ 8 = k · 4²
∴ k = 1/2
Again ....
x = 5 , y = ?
y = k·x²
y = 1/2 × 5²
= 25/2 = 12.5
