Consider the sequence whose first five terms are shown. -59 ,-67 ,-65 ,-53 ,-31 ,... The first term is ____ To calculate the second term, add _____ To calculate each additional term, increase the amount added by _____ (the _____ are blanks)
Step-by-step explanation:
The sequence is as follows :
-59 ,-67 ,-65 ,-53 ,-31 ,...
The first term = -59
The second term = -67
Common difference = second term - first term
[tex]=-67-(-59)\\\\=-8[/tex]
To calculate the second term add (-8).
To calculate each additional term, increase the amount added by -8.

A bag contains 70 pencils out of which 15 are green and 30 are blue. How many pencils of other colour are in the bag. A pencil is selected from a bag at random .What is the probability that it is blue?
Answer:
a) There are 25 pencils of other colour in the bag.
b) P(Blue) = 3/7
Step-by-step explanation:
A bag contains 70 pencils out of which 15 are green and 30 are blue.
a) How many pencils of other colour are in the bag?
This is calculated as:
70 - (15 + 30)
= 70 - 45
= 25 pencils
Hence, there are 25 pencils of other colour in the bag.
b) A pencil is selected from a bag at random .What is the probability that it is blue?
P(Blue) = Number of Blue pencils/Total number of Pencils
P(Blue) = 30/70
P(Blue) = 3/7

15 points and BRAINLIEST Alyssa invested $500 into an account. The value of the account after t years can be found using the function r(t) = 500(1.068). What is the percent annual rate of change
in the value of the account?
Answer:
annual rate: r = 0.068
Step-by-step explanation:
The formula is r(t) = P(1+r)^t
Since the time is already in years we just have to solve for the rate
1 + r = 1.068
r = 0.068
The rate of change in the value of account is 0.068
What is rate of change?
'Rate of change is used to mathematically describe the percentage change in value over a defined period of time.'
According to the given problem,
Annual rate:
r = 0.068
The formula is r(t) = [tex]P( 1 + r )^{t}[/tex]
Therefore, solving for the rate
⇒ 1 + r = 1.068
⇒ r = 0.068

Alex paid $6 for renting a movie for 3 days. Which graph shows the relationship between the costs of renting a movie for different days? (3 points) a A graph is shown with title Movie Rentals. The horizontal axis label is Days, and the vertical axis label is Cost of Rental in dollars. Points are plotted on the ordered pairs 1, 1, and 2, 2, and 3, 3. b A graph is shown with title Movie Rentals. The horizontal axis label is Days, and the vertical axis label is Cost of rental in dollars. Points are plotted on the ordered pairs 1, 3 and 2, 5, and 3, 7. c A graph is shown with title Movie Rentals. The horizontal axis label is Days, and the vertical axis label is Cost of rental in dollars. Points are plotted on the ordered pairs 1, 2 and 2, 4, and 3, 6 d A graph is shown with title Movie Rentals. The horizontal axis label is Days, and the vertical axis label is Cost of Rental in dollars. Points are plotted on the ordered pairs 2, 1 and 4, 2, and 6, 3.
Answer:
This is clearly a linear relationship. If Alex rented the movie for 0 days, he'd owe nothing. If he paid $6 for a 3-day rental, the slope of this line would be m = rise / run = $6/(3 days) = $2/day, which is positive.

A cell phone provider will allow you to buy a phone over time. They require a $50 initial payment and then charge $25 per month. If this situation were represented by a function, what would be the slope?
Answer:
25
Step-by-step explanation:
Given that:
Initial payment done for buying the phone = $50
Charges per month for the phone = $25 per month
To find:
The equation to represent the situation and its slope.
Solution:
First of all, let us assume that [tex]m[/tex] represents the number of months for which monthly is to be made.
Charges paid for one month = $25
Charges paid for [tex]m[/tex] months = $25[tex]m[/tex]
Total cost of the phone = Initial payment + Charges paid for [tex]m[/tex] months
[tex]C = 25m + 50[/tex]
It is a linear equation between two variables [tex]C[/tex] and [tex]m[/tex].
This equation can be compared with slope intercept form of a line.
Slope intercept form of a line is represented by:
[tex]y=Mx+c[/tex]
[tex]M[/tex] is the slope.
On Comparing, we get:
[tex]y = C, M = 25, x = m, c = 50[/tex]
Therefore, the slope is 25.
Which object is moving faster?
Answer:

Write an equation of the line through the point (-10, 0) with slope of -1/2
Answer:
y = 1/2x + 5
Step-by-step explanation:
We can use point slope form since we are given a point and the slope
y -y1 = m( x-x1)
where ( x1,y1) is a point and m is the slope
y -0 = 1/2 (x- -10)
y = 1/2( x+10)
y = 1/2x + 5

Answer:
cos(20°)
Step-by-step explanation:
The angle difference formula for cosine is ...
cos(α -β) = cos(α)cos(β) +sin(α)sin(β)
If we let α = 50° and β = 30° then this matches the given expression:
cos(50° -30°) = cos(50°)cos(30°) +sin(50°)sin(30°) = cos(20°)

In a certain school district, students from grade 6 through grade 12
last one? Honestly i have no idea haha sorry :( I’m kinda insecure you know what bye! :) merry Christmas
Options A, B and C are the correct answers.
Given that, the bar chart shows the relative frequencies of students from grades 6 to 12 who participate in the community service activity.
How do you find relative frequency?Relative frequency can be defined as the number of times an event occurs divided by the total number of events occurring in a given scenario.
Relative Frequency = Subgroup frequency/ Total frequency.
Relative Frequency = f/ n.
From the given bar chart we can see that
The maximum number of participating students was in grade 9.The number of participating students in grade 6 was equal to the number of participating students in grade 7.The relative frequency of all participating students in grades 6 and 7 combined was 0.60.Therefore, options A, B and C are the correct answers.
