The person whose purple paint will be bluer is Skylar.
Whose purple paint will be bluer?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.
In this case, Hassan mixes 1 cup of blue paint and 3 cups of red paint. The percentage for blue paint will be:
= 1 / (1 + 3) × 100
= 1/4 × 100
= 25%
Skylar mixes 5 cups of blue paint and 3 cups of red paint. The percentage for blue will be:
= 5 / (5 + 3) × 100
= 5/8 × 100
= 62.5%
Skylar has bluer paint.

Nikola likes to play horseshoes, where players try to score a ringer by throwing a horseshoe so it lands around a post. A player gets 2 attempts each round. Let R represent the number of ringers that Nikola scores in a round. Here's the probability distribution of R along with summary statistics. R=# of ringers 0 1 2 P(R) 0.75 0.20 0.05 Mean: HR=0.3 Standard deviation: OR 0.56 Nikola gets 3 points for each ringer that he scores. Let X represent the number of points that Nikola gets from ringers in a round. What are the mean and standard deviation of X?
The mean and standard deviation of X are 0.9 and 1.68 points.
Since Nikola gets 3 points for each ringer which he scores, then total points he gets from ringers could be determined by multiplying the number of ringers by 3.
So, X = R * 3 = 3R
Where:
R = numbers of ringers
X = total points Nikola gets from ringers
Given:
Mean : μR = 0.3
Standard deviation : σR = 0.56
Thus, multiplying by 3 will effects the mean as follows:
μX = 3 (μR)
= 3 (0.3)
= 0.9
And, multiplying by 3 also will effects the standard deviation as follows:
σX = 3 (σR)
≈ 3 (0.56)
≈ 1.68
Hence, the mean of X is 0.9 and and the standard deviation of X is 1.68.

Construct a geometric mean between a and c.
Geometric mean will be a line segment with length x such that x² = a × c.
What is Geometric Mean?Geometric mean of two line segments p and q is a line x such that it satisfies the formula x² = a × b or x/a = b/x.
To construct geometric mean, first simply draw a line segment and mark a point P anywhere on this line.
Mark the length of the line segment 'a' from the point P and mark the endpoint of 'a' as A. Now, in the same line, from the point P, mark the length of the given line 'c' and mark its endpoint as C.
Now, draw a perpendicular bisector of the resulting line PC. Then we get the midpoint of PC. Let this point be O.
Draw a semicircle with center O and the endpoints P and C.
Now draw a vertical perpendicular line from the point A until it cuts the semicircle. Let N be the point where this line touches the semicircle.
Now join P with N.
The line PN will be the geometric mean x such that a × c = x².
Hence the line segment PN is the geometric mean with length x.

Answer:
-2.5 ≤ x ≤ 0.6-0.75 < x < 0.5Step-by-step explanation:
You want the solutions to the following inequalities by any convenient method:
x(10x +19) ≤ 15(x +2)² > (3x +1)²ComparisonWe choose to rewrite these inequalities to be comparisons to zero. This is because our graphing calculator easily identifies the x-intercepts of a graph. We can look a the graph to tell where the function is above or below the x-axis.
f(x) = x(10x +19) -15; f(x) ≤ 0g(x) = (x +2)² -(3x +1)²; g(x) > 0GraphThe attached graph shows the solutions to be ...
f(x) ≤ 0 for -2.5 ≤ x ≤ 0.6g(x) > 0 for -0.75 < x < 0.5The values obtained for the first equation will be x ≤ 3/5 and x ≤ -5/2 and the values obtained for the second equation will be x < 1/2 and x < -3/4.
What is inequality?Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values. Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.
As per the given inequalities in the question,
1.
x(10x + 19) ≤ 15
Firstly, simplify it to the simpler form,
10x² + 19x - 15 ≤ 0
Solve the quadratic equation,
D = b² - 4ac
= 19² - 4(10)(-15).
D = 961
Now, use the formula,
(-b±√D)/2a
√D = √961 = 31
(-19 ± 31)/2(10)
So, the roots are:
1.
(-19 + 31)/20 = 12/20 = 3/5
Or, x ≤ 3/5
2.
(-19 - 31)/20 = -50/20 = -5/2
Or, x ≤ -5/2
2.
(x + 2)² > (3x + 1)²
Simplify the equation first.
x² + 4x + 4 > 9x² + 6x + 1
x² - 9x² + 4x - 6x + 4 - 1 > 0
-8x² - 2x + 3 >
8x² + 2x - 3 < 0
Now, find the roots for the equation,
D = b² - 4ac
D = 4 + 96
D = 100
Now, use the formula,
(-b ± √D)/2a
(-2 ± 10)/16
So, the roots are:
1. (-2 + 10)/16 = 1/2
Or, x < 1/2
2. (-2 - 10)/16 = -12/16 = -3/4
Or, x < -3/4

Time to think about your New Year's Resolution for the new year. Nora decided she needed more
exercise. She decided that starting with the first full week in 2023, she will do a 45-minute workout
four times a week ( four days during every seven-day week.) This means she will exercise four of the
days during the week of Jan, 1 through Jan. 7 and will do the same during the week from Jan. 8
through Jan. 14, etc. If Nora sticks to her resolution, what is the first possible date on which she will
complete 25 hours of exercise for the year?
The first possible date on which she will complete 25 hours of exercise for the year is on March 1.
How to calculate date?In general, dates can refer to a specific day on the calendar, such as January 1 or December 31. Dates can also refer to a specific point in time, such as a specific hour, minute, or second. In some cases, dates can also refer to a specific period of time, such as a year, month, or week.
Since Nora plans to do a 45-minute workout four times a week,
she will exercise for a total of 4 * 45 minutes = 180 minutes per week.
This means that each week, she will exercise for a total of 180 / 60 = 3 hours.
To complete 25 hours of exercise for the year,
Nora will need to exercise for a total of 25 / 3 = 8.3 weeks.
The first possible date on which she will complete 25 hours of exercise is therefore 8.3 weeks after Jan 1,

Solve for x in the equation x2-14x+31-63-
Ox=-16 or x = 2
O x=-7±3-√√7
Ox=-2 or x = 16
Ox=7±3√√√7
Answer:Value of x are 16 and -2
Step-by-step explanation:
Solve for x in the equation:
Subtract 63 from both sides we have;
To factor this equation as:
⇒
Take (x-16) common we have;
⇒
By zero product property we have;
x-16 = 0 or x+2 = 0
⇒x = 16 or x = -2
Therefore, the value of x are: 16 and -2
The value of x in the equation are x = -2 or x = 16.
What are Quadratic Equations?Quadratic equations are polynomial equations of second degree.
The general form of a quadratic equation is ax² + b x + c = 0.
Given is a quadratic equation,
x² - 14x + 31 = 63
We have to find the value of x.
x² - 14x + 31 - 63 = 0
x² - 14x - 32 = 0
Using the quadratic formula,
x = [14 ± [tex]\sqrt{(-14)^2-(4*1*-32)}[/tex]] / 2
= (14 ± √324) / 2
= (14 ± 18) / 2
x = 14 + 18 / 2 or x = 14 - 18 / 2
x = 16 or x = -2
Hence the value of x are x = 16 or x = -2.

are 4 people and 9 different assignments. Each person should receive one
assignment. Assignments for different people should be different. How many ways
are there to do it?
The ways to assign for different people is 126 ways
How to determine the ways of selection?From the question, we have
Total number of questions, n = 9
Numbers to people, r = 4
The number of ways of selection could be drawn is calculated using the following combination formula
Total = ⁿCᵣ
Where
n = 9 and r = 4
Substitute the known values in the above equation
Total = 9C4
Apply the combination formula
ⁿCᵣ = n!/(n - r)!r!
So, we have
Total = 9!/5!4!
Evaluate
Total = 126
Hence, the number of ways is 126

classify the following random variable according to whether it is discrete or continuous. the number of goals scored in a hockey game
The number of goals scored in a hockey game is a discrete random variable.
A discrete random variable has a countable number of different possible values, such as 0,1,2,3,4, etc. Usually, but not always, discrete random variables are counted. If a random variable has a limited range of possible values, it is discrete.
The number of children in a household, the Friday night movie attendance, the number of patients at a doctor's office, and the number of faulty light bulbs in a box of ten are a few examples of discrete random variables. A discrete random variable's probability distribution is a table of the probabilities connected to each of its potential values.
