Answer:
A. [tex] y = \frac{1}{4}x + 2 [/tex].
Step-by-step explanation:
Equation of a line in slope-intercept form, is given as [tex] y = mx + b [/tex].
Given a slope (m) of ¼, and y-intercept (b) of 2, we can get the equation if the line by substituting m = ¼, and b = 2 into [tex] y = mx + b [/tex].
Thus, the equation of the line would be:

An investment has probabilities 0.15, 0.34, 0.44, 0.67, 0.2 and 0.15 of giving returns equal to 50%,
39%, -4%, 20%, -25%, and 42%. What are the expected returns and the standard deviations of
returns?
Answers
The expected returns is 33.7% and the standard deviations of returns is 38.73%.
What is standard deviation?In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.
Now given probabilities are,
probabilities P = 0.15, 0.34, 0.44, 0.67, 0.2 and 0.15
Given returns on the probabilities,
returns r = 50%, 39%, -4%, 20%, -25%, and 42%
So, Expected rate of returns = ∑Pr
⇒ Expected rate of returns = 0.15(50) + 0.34(39) + 0.44(-4) + 0.67(20) + 0.2(-25) + 0.15(42)
⇒ Expected rate of returns = 7.5 + 13.26 - 1.76 + 13.4 - 5 + 6.3
⇒ Expected rate of returns = 33.7%
Now standard deviation S is,
Square root of the difference squared between each value and the mean, multiplied by the probability.
S = √{0.15(50 - 33.7)² + 0.34(39 - 33.7)² + 0.44(-4 - 33.7)² + 0.67(20 - 33.7)² + 0.2(-25 - 33.7)² + 0.15(42 - 33.7)²}
⇒ S = √{0.15(16.3)² + 0.34(5.3)² + 0.44(-37.7)² + 0.67( - 13.7)² + 0.2(-58.7)² + 0.15(8.3)²}
⇒ S = √{0.15(265.69)+ 0.34(28.09) + 0.44(1421.29) + 0.67( - 187.69) + 0.2(3445.69)²\ + 0.15(68.89)}
⇒ S = √{39.85 + 9.55 + 625.36 + 125.75 + 689.13 + 10.33}
⇒ S = √{1499.97}
⇒ S = 38.73%
Thus, the expected returns is 33.7% and the standard deviations of returns is 38.73%.

The first three terms of an arithmetic sequence are as follows 9,4,-1 find the next two terms
Answers
The following two terms of an arithmetic progression are -6 and -11.
What is an arithmetic sequence?
An arithmetic sequence is defined as a progression of numbers such that the difference between successive terms is consistent. It is also called Arithmetic Progression. The formula for tthe last term of an AP is given as: an = a + (n-1)d, here, a is the first term, n is the number of terms and d is the difference between two successive terms.
Finding the two terms of an arithmetic sequence
The first three terms of an arithmetic sequence are given by:
a1 = 9
a2 = 4
a3 = -1
Now, we want to calculate a4 and a5
Using the formula for calculating the next term of an arithmetic progression, we get,
a4 = a + (n-1)d, where n = 4 and d = 5
a4 = 9 + (4-1)(-5)
a4 = 9 - 15
a4 = -6
Further, a5 = a + (n-1)d, where n = 5 and d = 5
a5 = 9 + (5-1)(-5)
a5 = 9 - 20
a5 = -11
Hence, the next two terms of an AP are -6 and -11.

Hope this helps!!
The equation that could be used to determine x is [tex]\frac{11+x}{53+x} \leq 0.300[/tex].
What is inequality?Inequality is a relation that makes a non-equal comparison between two expressions.
Batting average of William = 11/53
Desired batting average = 0.300
Suppose the number of more hits in a row to have desired batting average =x
Number of hits now =11+x
Number of bats now =53+x
It is given that the batting average should be a minimum of 0.300.
This means [tex]\frac{11+x}{53+x} \leq 0.300[/tex]
Therefore, the equation that could be used to determine x is [tex]\frac{11+x}{53+x} \leq 0.300[/tex].

The store is selling lemons at $0.66 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy enough lemons to make three 9-inch lemon pies,each requiring half a cup of lemon juice?
Answers
Answer:
$7.92
Step-by-step explanation:
1 lemon = 2 tbsp = $0.66
1 pie = 1/2 cup
So take 3 x 1/2 = 1 1/2 cups. Now we know that we need 1 1/2 cups of lemon juice. So convert 1 1/2 cups into tbsp and you get 24 tbsp. Now since 1 lemon is equal to 2 tbsp divide the 24 tbsp by 2 and you get 12. This 12 represents the amount of lemons you need to buy. Since 1 lemon is $0.66 take that and multiply it by the amount of lemons you need (12x0.66) now you get $7.92.
You need $7.92 to but 12 lemons to make three 9 inch lemon pies.

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
1 cup of lemon juice requires around 16 tablespoons of of juice.
1 lemon = 2 tbsp = $0.66
1 pie = 1/2 cup
number of cups = 3 x 1/2 = 1 1/2 cups.
Now we know that we need 1 1/2 cups of lemon juice. convert 1 1/2 cups into tablespoons and you get 24 tablespoons .
Now since 1 lemon is equal to 2 tbsp divide the 24 tbsp by 2
number of tablespoons = 24/2 = 12.
This represents the amount of lemons you need to buy.
Since 1 lemon is $0.66 take that and multiply it by the amount of lemons number of lemons = (12x0.66) = $7.92.
WE need $7.92 to but 12 lemons to make three 9 inch lemon pies.

Answers
Answer:
12%
Step-by-step explanation:
Add each number of students in the graph together. 1 + 6 + 2 + 3 = 12, so it's 12%.
Percentage of students who responded to the survey is 48 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
The total number of students in the survey = 25 students
The number of students who played Violin = 1 student
The number of students who played Piano = 6 students
The number of students who played Guitar = 2 students
The number of students who played Drums = 3 students
So ,
Total number of students who played instruments =
Number of students who played Violin + Number of students who played Piano + Number of students who played Guitar + Number of students who played Drums
Total number of students who played instruments = ( 1 + 6 + 2 + 3 )
= 12 students
Now ,
Percentage of students who played the instruments = Percentage of students who responded to the survey
And ,
Percentage of students who responded to the survey =
( Total number of students who played instruments / Total number of students in the survey ) x 100
Percentage of students who responded to the survey = ( 12 / 25 ) x 100
= 12 x 4
= 48 %
Therefore , percentage of students who responded to the survey = 48 %
Hence , percentage of students who responded to the survey is 48 %
