A Survivorship Life Insurance Plan insures how many people under one plan?
More than three
One
Three

A single survivorship life insurance policy can provide coverage for up to two persons.
What is meant by Life Insurance Plan?A contract between an insurance policy holder and an insurer or assurer in which the insurer agrees to pay a specified beneficiary a certain amount of money upon the death of an insured person is known as life insurance (or life assurance, particularly in the Commonwealth of Nations) (often the policyholder). Other occurrences, such critical illness or terminal disease, may also result in payment, depending on the contract. Usually, a premium is paid by the policyholder, either on a regular basis or all at once. Other costs, such burial costs, can be covered by the benefits.
Consequently, a single survivorship life insurance policy might provide coverage for two persons. These policies, which are also known as second-to-die joint life insurance, only provide a death benefit following the passing of both policyholders.

Jaylen and Ryan are saving up for holiday gifts for their families. Jaylen has $340 in his savings account and earns an additional $15 per week from doing chores. Ryan has $220 in her savings account and earns $25 per week from doing chores. How many weeks will it take to save up the same amount of money?
Jaylen and Ryan will have same amount of money after 12 weeks .
Let the no of weeks after which both of them will have equal amount be x
therefore, after x weeks the amount of money in
Jaylen's account = 340 + 15x
Ryan's account = 220+ 25x
Now, since these amount is equal
therefore,
340 + 15x = 220+ 25x
on solving this equation we get ,
=>340 - 220 = 25 x - 15x
=> 120 =10x
=> x = 12
First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable).
Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.

The image point of (9,3) after the transformation r x-axis is (-9, -3 ).
How does transformation of a function happens?The transformation of a function may involve any change.
Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
Since we know that Horizontal shift (also called phase shift):
Left shift by c units:
y=f(x+c) (same output, but c units earlier)
Therefore, Under a counterclockwise
a point (x, y ) → (- x, - y ) , thus
(9, 3 )→ (-9, -3 )
Therefore, the image point of (9,3) after the transformation r x-axis is (-9, -3 ).

For the three-part question that follows, provide your answer to each question in the given workspace. Identify each part with a coordinating response. Be sure to clearly label each part of your response as Part A, Part B, and Part C.
A bag contains three blue marbles, five red marbles, and four green marbles.
Part A: What is the probability of selecting three marbles where one is blue and two are green?
Part B: What is the probability of selecting one blue marble and then selecting three red marbles?
Part C: In your own words, write a short paragraph that explains your work for Parts A and B.
The probabilities for the given problem is calculated as 0.081 and 0.06 respectively.
What is probability?Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.
The probability of any event always lie in the close interval of 0 and 1 [0,1].
The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.
Given that,
There are 3 blue marbles, 5 red marbles and 4 green marbles.
Then, the total number of marbles is 12.
The given problem can be solved as follows,
Part A:
The probability of getting 1 blue and 2 green marbles is,
P( 1 blue and 2 green) = (³C₁ × ⁴C₂)/¹²C₃
= ( 3 × 6)/ 220
= 9/110
= 0.081
Part B:
The probability of selecting one blue marble = 3/12 = 1/4
After one blue marble is selected, the remaining number of marbles is 11.
Thus, probability of selecting 3 red marbles is,
⁵C₃/¹¹C₃
= 10/165
= 0.06
Part C:
In the Part A the probability is calculated by taking the ratio of total number of ways of selecting 3 marbles and the number of ways of selecting 1 blue and 2 green marbles.
And, in Part B the number of ways is calculated from the remaining number of marbles after one blue marble is chosen.
Hence, the probabilities for the given parts in the question are 0.081 and 0.06 respectively.

The value of x when f(x) of 8 according to the graph is; 4.
How to calculate value of x?In order to determine a point's coordinates in a coordinate system, you must do the opposite. Start at the point and move in a vertical line in either an upwards or downwards direction to the x-axis. Here is the x-coordinate for you. Next, repeat the process while following a horizontal line to determine the y-coordinate.
According to the graph;
To determine the value of x when f(x) = 8.
We must plot a line of the equation; y = 8.
This y = 8 line produces a horizontal line.
The point at which the horizontal line, y = 8 intersects the given graph has an x coordinate.

What is the equation of a line that is parallel to 3x + 4y = 15 and passes through the point (8, - 2)?
Enter your answer in slope-intercept form (y=mx+b) in the box.
Step-by-step explanation:
in the slope- intercept form
y = mx + b
m is the slope, b is the y-intercept (the y-value when x = 0).
a parallel line must have the same slope, but a different y- intercept.
as you can see, the slope is always the factor of x, when we have a "y = ..." form.
so, coming from
3x + 4y = 15
4y = -3x + 15
y = (-3/4)x + 15/4
the slope is therefore -3/4.
b we get by using the given point coordinates in the equation :
-2 = (-3/4)×8 + b = -24/4 + b
b = -2 + 24/4 = -2 + 6 = 4
so, the full equation is
y = (-3/4)x + 4
