Topic - Arithmetic Progression ( AP )Given - a general term for a sequence.To find - the 150th term of the given sequenceso let's start ~
General term , [tex] A_{n} [/tex] = 3n + 10
let's consider certain values of n to get some information with us which will help us solve the problem further !
let's first consider , n = 1 ! then ,
[tex]3n + 10 = 3(1) + 10 \\ \dashrightarrow \: 13[/tex]
now , let's consider n = 2
[tex]3n + 10 = 3(2) + 10 = 6 + 10 \\ \dashrightarrow \: 16[/tex]
then , let's consider n = 3
[tex]3n + 10 = 3(3) + 10 = 9 + 10 \\ \dashrightarrow \: 19[/tex]
hence ,
now we've with us an AP which is as follows -
[tex]13 \: , \: 16 \: , \: 19 \: ......[/tex]
from this Arithmetic Progression ,
we can know that
a = first term = 13
d = common difference = 16 - 13 = 19 - 16 = 3
now ,
[tex]A _{n} = a + (n - 1)d \\ \implies \: A _{150} = 13 + (149)(3) \\ \implies \: A _{150} = 13 + 447 \\ \pink{\implies \: A _{150} = 460}[/tex]

Step-by-step explanation:
Jim's currect age is x.
In 16 years, JIm will be x + 16.
In 4 years, Jim will be x + 4.
x + 16 = 3x
-2x = -16
x = 8
x + 4 = 8 + 4 = 12

Given P(A) = 0.51, P(B) = 0.79, and P(A or B) = 0.66, are events A and B mutually exclusive?
Answer: No, the events are not mutually exclusive
Work Shown:
P(A and B) = P(A) + P(B) - P(A or B)
P(A and B) = 0.51 + 0.79 - 0.66
P(A and B) = 0.64
Since the result is not zero, this means the events are not mutually exclusive.
Mutually exclusive events are ones that cannot happen at the same time. Example: getting a "2" and a "3" on the same roll of a number cube.

Any equation that starts with y =7x
Parallel lines have the same gradient.
(No options to choose from)
Hope this helps!
Any Equation start with y = 7x + c is parallel to given equation.
What is Parallel lines?To determine whether or not two lines are parallel, the formula for parallel lines is used. When we have the slopes of two lines that we want to compare, we can use the parallel line formula. The parallel lines' distances never change.
Given Equation
y = 7x + 5
and line k
line k is parallel to equation y = 7x + 5
for parallel lines
The formula for determining whether two lines are parallel is as follows for any two lines with the equations y = m₁ x + c₁ and y = m₂x + c₂:
where m₁ and m₂ are the slopes of the two lines. m₁ = m₂.
given equation y = 7x + 5,
here m₁ = 7 and c₁ = 5
the line which is parallel to equation should be
y = 7x + c
where m₂ = m₁ = 7 and c₂ = c
Hence equation y = 7x +c is parallel to given equation.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of people who voted for the comedy film be = A
Now , the equation will be
The total number of people = 280 people
The percentage of people who voted for the best comedy film = 65 %
So , number of people who voted for the comedy film A = percentage of people who voted for the best comedy film x total number of people
Substituting the values in the equation , we get
Number of people who voted for the comedy film A = ( 65 / 100 ) x 280
On simplifying the equation , we get
Number of people who voted for the comedy film A = 0.65 x 280
Number of people who voted for the comedy film A = 182 people
Therefore , the value of A is 182 people
Hence , the number of people is 182 people

For each value of y, determine whether it is a solution to -2y+75-5.
Is it a solution?
Answer:
• No
• Yes
• Yes
• No
Step-by-step explanation:
To determine if the 4 given values of y are solutions to the inequality, start by solving the inequality. Solving an inequality is just like that of an equation, except that the direction of the sign changes when the inequality is divided by a negative number.
-2y +7≤ -5
Subtract 7 on both sides:
-2y≤ -5 -7
-2y≤ -12
Divide by -2 on both sides:
y≥ 6
This means that the solution can be 6 or greater than 6.
-10 and 3 are smaller than 6 and are not a solutions, while 7 and 6 satisfies the inequality and are therefore solutions.
_______
Alternatively, we can also substitute each value of y into the inequality and check if the value is less than or equal to -5.
Here's an example to check if -10 is a solution.
-2y +7≤ -5
When y= -10,
-2y +7
= -2(-10) +7
= 20 +7
= 27
Since 27 is greater than 5, it is not a solution to the inequality.

nearest tenth.
In your answer, give the volume of the cone rounded to the nearest tenth, and then
explain how you calculated it. (Note: type out all of your work AND type out your
explanation for FULL credit.)
Answer:
39.5 in^3
Step-by-step explanation:
lol someone had the same question
The formula for a cone is (pi)(r^2)(h/3)
Since we have to use 3.14 for pi, we plug 3.14 in for pi:
(3.14)(r^2)(h/3)
The radius is 2 and the height is 8, so we plug in those numbers:
(3.14)(2^2)(8/3)
Simplify:
(3.14)(4)(2.666...)
Multiply:
(12.56)(2.666...) -> 39.49333...
Finally, we round 39.49333... to the tenths place:
39.5

Find the slope-intercept equation
Please help me
Answer:
[tex]y = -\frac{1}{3}x + 5[/tex]
Step-by-step explanation:
To being, slope intercept form is the infamous y = mx + b form. In which, m is equal to the slope and b is equal to the y-intercept. (1) To solve this, begin by finding two points of the line. One easy point to find is when x = 0 as it intersects with the y-axis. Two points are: (0,5) and (-3,6). (2) Next, use the slope formula to solve for the slope. The slope formula is [tex]\frac{y2-y1}{x2-x1}[/tex]. Plug in the y and x values; [tex]\frac{6-5}{-3-0}[/tex]. Simpliify the fraction; [tex]\frac{1}{-3}[/tex] --> [tex]-\frac{1}{3}[/tex]. Therefore -1/3 is our slope. (3) To solve for b, the y-intercept, set up the slope-intercept equation with the newfound slope (y = -1/3x + b) and plug in a point for the y and x values. Doing this will isolate the b so you can solve for it.
6 = -1/3(-3) + b
6 = 1 + b
-1 -1
5 = b
Therefore the y-intercept (b) is 5. (4) The final step is to combine the information into the slope-intercept form; y = -1/3x + 5. Good luck!
