Alma need to use 6 cups of blue paint and 4 cups of red paint with the 2 cups of white paint.
Here, Alma makes 5 cups of her favorite shade of purple paint by mixing
3 cups of blue paint,
1 1/2 cups of red paint,
and 1/2 a cup of white paint.
Alma has 2 cups of white paint.
The ratio of blue to the white paint is:
3 : (1/2)
so, for 2 cups of white paint,
3 : (1/2) = x : 2
x = 6 cups of blue paint
The ratio of red to the white paint is,
3: (1 1/2)
3 : (3/2)
So, for 2 cups of white paint,
3 : (3/2) = y : 2
y = 4 cups of red paint

If diameter EF bisects BC, what is the angle of intersection?
Answer:
The angle of the intersection is 90 degrees
Step-by-step explanation:
How I know this is because EF is the diameter, which means that arc EF is equal to 180 degrees. Because we know this that means when it is spilt into two parts, the arc and angle measure has to be 90 degrees.
Another way to do this is to remember that a circle is 360 degrees and the circle is split into 4 parts. So all you have to do is divide 360/4 to get 90. Your answer.

Sophia wishes to retire at age 65
with $1,600,000
in her retirement account. When she turns 28
, she decides to begin depositing money into an account with an APR of 9%
compounded monthly. What is the monthly deposit that Sophia must make in order to reach her goal? Round your answer to the nearest cent, if necessary
Answer:
To determine the monthly deposit that Sophia must make in order to reach her retirement goal, we can use the formula for the future value of an annuity:
FV = P * ((1 + r/n)^(nt) - 1) / (r/n)
where:
FV = future value of the annuity (which is Sophia's retirement goal of $1,600,000)
P = monthly deposit
r = annual interest rate (which is 9%)
n = number of times interest is compounded per year (which is 12 for monthly compounding)
t = number of years until retirement (which is 65 - 28 = 37)
Substituting the given values, we get:
1600000 = P * ((1 + 0.09/12)^(12*37) - 1) / (0.09/12)
Simplifying and solving for P, we get:
P = 1600000 * (0.09/12) / ((1 + 0.09/12)^(12*37) - 1)
P ≈ $524.79
Therefore, Sophia must make a monthly deposit of approximately $524.79 in order to reach her retirement goal of $1,600,000.

4x-4=12-4x
4x+4xd=12+4
8x=16
x=2
Answer:
x=2
Step-by-step explanation:
Step 1: Distribute
To solve this problem, the first step is distributing the four and the 2.
[tex]4(x-1)=2(6-2x)\\\\4x-4=12-4x[/tex]
So this is our simplified problem.
Step 2: Solve for x
Step 2a: Add 4x to both sides:
(This is because we do not have two variables in the equation, making it easier to solve.
[tex]4x+4x-4=12-4x+4x\\\\8x-4=12+0\\\\8x-4=12[/tex]
Step 2b: Add 4 to both sides:
(We do this to leave the variable on one side and the constant on the other. )
[tex]8x-4+4=12+4\\\\8x+0=16\\\\8x=16[/tex]
Step 2c: Divide both sides by 8:
(The reason why we do this is to isolate the variable without any coefficient in front.)
[tex]\frac{8x}{8} =\frac{16}{8} \\\\x=2[/tex]
Suppose X~N(12,2). The empirical rule stated that about 68% of the x values lie within one stands deviation of the mean. Between what x Values does 68% of the data lie?
Answer:
Suppose X ~ N(12,2) represents a normal distribution with mean 12 and standard deviation 2. According to the empirical rule, about 68% of the x values lie within one standard deviation of the mean .
We can calculate the endpoints of the interval that represents one standard deviation from the mean as follows:
Lower endpoint: 12 - 2 = 10
Upper endpoint: 12 + 2 = 14
Therefore, about 68% of the x values lie between 10 and 14 1.

The solution to the inequality f(x²-2) < f(7x-8) over D₁ = (-∞, 2) is:
-∞ < x < 1 or 1 < x < 6 or 6 < x < 2
Solving Inequality in a given domainGiven the inequality,
f(x²-2) < f(7x-8) over D₁ = (-∞, 2)
We need to find the values of x that satisfy this inequality.
Since we know that f is increasing over its domain, we can compare the values inside the function to determine the values of x that satisfy the inequality.
First, we can find the values of x that make the expressions inside the function equal:
x² - 2 = 7x - 8
Simplifying, we get:
x² - 7x + 6 = 0
Factoring, we get:
(x - 6)(x - 1) = 0
So the values of x that make the expressions inside the function equal are x = 6 and x = 1.
We can use these values to divide the domain (-∞, 2) into three intervals:
-∞ < x < 1, 1 < x < 6, and 6 < x < 2.
We can choose a test point in each interval and evaluate
f(x² - 2) and f(7x - 8) at that point. If f(x² - 2) < f(7x - 8) for that test point, then the inequality holds for that interval. Otherwise, it does not.
Let's choose -1, 3, and 7 as our test points.
When x = -1, we have:
f((-1)² - 2) = f(-1) < f(7(-1) - 8) = f(-15)
Since f is increasing, we know that f(-1) < f(-15), so the inequality holds for -∞ < x < 1.
When x = 3, we have:
f((3)² - 2) = f(7) < f(7(3) - 8) = f(13)
Since f is increasing, we know that f(7) < f(13), so the inequality holds for 1 < x < 6.
When x = 7, we have:
f((7)² - 2) = f(47) < f(7(7) - 8) = f(41)
Since f is increasing, we know that f(47) < f(41), so the inequality holds for 6 < x < 2.
Therefore, the solution to the inequality f(x²-2) < f(7x-8) over D₁ = (-∞, 2) is:
-∞ < x < 1 or 1 < x < 6 or 6 < x < 2

A bag has 6 blue cubes, 3 red cubes, and 3 green cubes. If you draw a cube and replace it in the bag 120 times, which of the following amounts would you expect to pull?
The expected values are 60 blues, 30 reds and 30 greens
Which amount would you expect to pull?From the question, we have the following parameters that can be used in our computation:
6 blue cubes, 3 red cubes, and 3 green cubes
This means that we have the following proportions
Blue = 6/(6 + 3 + 3) = 1/2
Red = 3/(6 + 3 + 3) = 1/4
Green = 3/(6 + 3 + 3) = 1/4
If you draw a cube and replace it in the bag 120 times, we have
Blue = 1/2 * 120 = 60
Red = 1/4 * 120 = 30
Green = 1/4 * 120 = 30
Hence, the expected values are 60 blues, 30 reds and 30 greens

A researcher started tracking the number of mice in the lab.
Which of the following equations models how many mice there will be in the lab after 10 months?
Select one:
m(10) = 3 + 2(10)
m(10) = 2(3)^10
m(10) - 3(10)^2
m(10) = 3(2)^10
The correct equation that models how many mice there will be in the lab after 10 months is m(10) = 3 × 2^10.
We have,
From the given data, we can see that the number of mice is being multiplied by 2 every month.
That means the growth is exponential.
We can use the formula for exponential growth:
[tex]m(t) = a \timesr^t[/tex]
where m(t) is the total number of mice after t months, a is the initial number of mice (when t = 0), and r is the common ratio
From the given data, we can see that when t = 0, there are 3 mice.
So, a = 3.
Also, we can see that the common ratio is 2 (i.e., the number of mice is being multiplied by 2 every month).
Now,
The equation that models how many mice there will be in the lab after 10 months is:
m(10) = 3 × 2^10
Simplifying this equation gives:
m(10) = 3 × 1024
m(10) = 3072
Therefore,
The correct equation that models how many mice there will be in the lab after 10 months is m(10) = 3 × 2^10.

Jolene invests her savings in two bank accounts, one paying 6 percent and the other paying 10 percent simple interest per year. She puts twice as much in the lower-yielding account because it is less risky. Her annual interest is 8602 dollars. How much did she invest at each rate?
The amount she invested at each rate of interest for the simple interest are $39,100 and $78,200.
Given that,
Jolene invests her savings in two bank accounts.
Rate of interest for one account = 6% per year
Rate of interest for the other account = 10% per year
Let x be the principal amount invested in the account yielding 10% interest.
Interest amount = 0.1x
Principal amount in the account of 6% interest = 2x
Interest amount = 0.06 × 2x = 0.12x
Annual interest = $8602
0.1x + 0.12x = 8602
0.22x = 8602
x = $39,100
Amount invested for 10% interest account = $39,100
Amount invested for 6% interest account = 2 × $39,100 = $78,200
Hence the amount invested are $39,100 and $78,200.

How to find the missing length of the triangle?The Law of Cosines is defined as a numerical formula that expresses the relationship between the side lengths and points of any triangle. It usually expresses that the square of any particular side of a triangle is equal to the number of squares of the other different sides short two times the result of those sides and the cosine of the point between them.
Numerically, the Law of Cosines can be expressed as:
c² = a² + b² - 2abcos(C),
where c is the length of the side inverse to the point C, and an and b are the lengths of the other different sides.
Thus, the distance here is expressed as:
