Step-by-step explanation:
Next term is - 51
Use formula Tn=a+(n-1)d
a=the first term of the sequence which is - 15
d=the difference between the terms which is - 9
Substitute
Tn=-15+(n-1)(-9)
Tn=-15+9-9n
Tn=-9n-6
From this you will be able to generate all the terms in the pattern
If they say determine the 50th term just substitute 50 by n
Tn=-9(50)-6
Tn=-450-6
Tn=-456

Answer:
60
Step-by-step explanation:
hello there!
If you didn't know an exterior angle of a triangle is equal to the sum of its opposite interior angles
to be more specific ∠5=∠4+∠3
we are given ∠5 and ∠4 and we need to find ∠3
So we plug in what we have and solve for ∠3
130 = 70 + ∠3
subtract 70 from each side
130 - 70 = 60
we're left with ∠3 = 60

Do you know to use the formulas?
What is the difference between arithmetic and geometric?
Do you know how to find the average rate of change?
What is sigma notation? What are the parts?
What does it mean for a graph to be discrete? Continuous?
Answer:
down here. I dont expect you to copy paste
Step-by-step explanation:
Arithmetic sequence: An arithmetic sequence is a sequence where each term increases by adding/subtracting some constant k.
Arithmetic series : An arithmetic series is the sum of a sequence in which each term is computed from the previous one by adding (or subtracting) a constant
Difference: A sequence is defined as an arrangement of numbers in a particular order. On the other hand, a series is defined as the sum of the elements of a sequence.
How to use them : maybe
Geometric Sequence : A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.
Geometric series : In mathematics, a geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms.
Difference: A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.In mathematics, a geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms.
How to use: maybe
Arithmetic and geometric difference: The main difference between arithmetic and geometric sequence is that arithmetic sequence is a sequence where the difference between two consecutive terms is constant while a geometric sequence is a sequence where the ratio between two consecutive terms is constant.
Average rate of change : To find the average rate of change, we divide the change in the output value by the change in the input value.
Sigma notation :Often mathematical formulae require the addition of many variables Summation or sigma notation is a convenient and simple form of shorthand used to give a concise expression for a sum of the values of a variable.
Graph: A continuous function allows the x-values to be ANY points in the interval, including fractions, decimals, and irrational values. A discrete function allows the x-values to be only certain points in the interval, usually only integers or whole numbers.

Veronikas five test scores are 59 80 95 and 93 if the outlier of 59 is removed what is the mean absolute deviation of the remaining four test scores?
Complete Question
Veronikas four test scores are 59, 80, 95, 88 and 93 if the outlier of 59 is removed what is the mean absolute deviation of the remaining four test scores?
Answer:
5
Step-by-step explanation:
We have the four test scores
80, 95, 88 and 93
Step 1
We find the mean of the 4 test scores
= 80 + 95 + 88 + 93/4
= 356 / 4
89
Step 2
The formula for Mean Absolute Deviation =
Summation( x - Mean)/n
Hence,
|(80 - 89 )+( 95 - 89) + (88 - 89) + (93 - 89)|/5
= 9 + 6 +1 + 4/4
= 20/4
= 5

Which trend line properly describes the data relationship in the scatterplot?
Answer:
The correct answer is B :)))
Step-by-step explanation:
2021
Definition - Trend line is referred to as a line of the best fit, which lines that are used to represent the behavior of a set of data to determine if in a certain pattern. Thus, A trend line is an analytical tool used most often in conjunction with a scatter plot to see if there is a relationship between two variables.
The main purposes of a trend line are:Predicting unknown or future data points are: This graph is shown to temperatures for ten days. Also, we can be attempting to predict the temperature on the 11th day based on behalf of this graph, then we can estimate would be 70.5 degrees. It also mentions a graph below. Then, If a set of points exhibits a positive trend, Then Determine a negative trend or no trend at all. Looking at the red trend lines in the examples which are mentioned below with sets of data.

Lisa purchased almonds for $3.00 per pound and she spent $24.90. How many pounds of almonds did she purchase? The price went up to $3.50 a pound and lisa only had 25.00 how many pounds of almonds can she buy and whats her chance?
Answer:
1. Lisa purchased almonds for $3.00 and spent $24.90.
The quantity of almonds bought is therefore:
= Total amount spent / Cost per pound
= 24.90 / 3
= 8.3 pounds
2. If the price goes up to $3.50 per pound and the maximum Lisa can spend is $25, the number of pounds she can get is:
= Maximum amount for almonds / Price per almonds
= 25 / 3.5
= 7.14 pounds

Find the area of the figure and choose the appropriate result.
1 m
3.5 m
8 m
Answer:
Area if figure = 22 m²
Step-by-step explanation:
Given:
Length of rectangle = 8 m
Width of rectangle = 1 m
Base of triangle = 8 m
Height of triangle = 3.5 m
Find:
Area if figure
Computation:
Area if figure = Area of rectangle + Area of triangle
Area if figure = [l x b] + [(1/2)(b)(h)]
Area if figure = [8 x 1] + [(1/2)(8)(3.5)]
Area if figure = 8 + 14
Area if figure = 22 m²
The population of Dawn land is changing exponentially. This change is modeled by the function f(x) = 60,000(1.01)x . Interpret the function to describe how the population changes. Explain how you know.
Answer:
The function has an initial population size of 60,000 which increase at a rate of 1%
Step-by-step explanation:
Given the expression :
f(x) = 60,000(1.01)^x
Since 1.01 > 1 (exponential
The general form of an Exponential growth function.
y = p(1 + r)^x
p = 60000 = initial population
1 + r = 1.01 ; where r = growth rate
r = 1.01 - 1 ; r = 0.01 =
r = 0.01 * 100% = 1% growth rate
