Today, Austin's age
is 1/4 of Stephanie's
age. In 4 years,
Austin's age will be
2/5 of Stephanie's age.
How old is Stephanie
today?
Answers
Answer: Steph is 16 today
Step-by-step explanation:
Austin age today = x
Austin in 4 years = x+4
Steph age today = 4x (because Austin is 1/4 her age today)
Steph age in 4 years is 4x + 4
In 4 years Austin's age is 2/5 of Steph's, so:
2/5 (x+4) = 4x + 4
Now solve for x!
x+4 = (8/5)x + 8/5
12/5 = (3/5)x
Therefore Austin is 4 years old today (x=4) and...
Steph age today = 4x = 4x4 = 16

Find the component form of the vector that translates (3, − 2) to ′(− 1, 4)
Answers
The vector that translates P to P' is (-4 , 6)
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x).
The points are given;
[tex]{P = (3, -2)}\\{P' = (-1, 4)}[/tex]
The translation rule is calculated as:
{(x,y) = P' - P}
So, we have:
{(x,y) =(− 1, 4) - (3, − 2)}
Combine the terms;
{(x,y) = (-1 -3 , 4 + 2)}
{(x,y) = (-4 , 6)}
Express as vectors;
(x, y) = (-4 , 6)
Hence, the vector that translates P to P' is (-4 , 6)

Answers
The probability that 72% or more of the women in the sample have been on a diet is, 0.1736.
What is probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.
As given a sample survey interviews an SRS of 209 college women. suppose that 69% of all college women have been on a diet within the last 12 months.
p = 0.69
1 - p = 0.31
n = 209
μp = p = 0.69
σp = √(p(1-p))/n = √(0.69*0.31)/209 = 0.03199
= 1 - p(p < 0.72)
= 1 - p((p - μp) / σp < (0.72 - 0.69) / 0.03199)
= 1 - p(z < 0.94)
= 1 - 0.8264

Answers
Answer:
1. 30 years old
2. 7 years old
3. 5 hours
Step-by-step explanation:
We can solve all of these problems using algebraic equations.
1. In this question, we will use variable x to represent the age of Mrs. Olsen's daughter.
In 10 years, x - 20 = 2x. That means that in 10 years, Mrs. Olsen will be 40 years old. That means she is 30 right now.
2. In this question, we will use variable x to represent the age of Alyssa.
If, in 30 years, their total age is 88, their current total is 28. Tyler is 3 times as old as Alyssa, so Tyler is 21 and Alyssa is 7.
3. Ryan leaves home at 50 mph. That means, in an hour Ryan will be 50 miles away from home. At that point, Jacob leaves home at a speed of 60 mph, so the gap between them closes by 10 miles each hour. That means that Jacob will take 5 hours to catch up, counting from when he left (how far is this workplace jeez?!?!?!?).
We could also represent this with a graph.
Hour 1: R = 50, J = 0 (Jacob leaves after this hour so it doesn't count for the answer)
Hour 2: R = 100, J = 60
Hour 3: R = 150, J = 120
Hour 4: R = 200, J = 180
Hour 5: R = 250, J = 240
Hour 6: R = 300, J = 300
Which of the following is NOT a solution to -4x + 9 > -3
A: -3
B: -1
C: 3
D:5
Answers
Answer:
D
Step-by-step explanation:
-4x + 9 ≥ -3 Subtract 9 from both sides
-4x ≥ -12 Divide both sides by -4. When you divide both sides by a negative number, you must flip the inequality sign.
x ≤ 3
D: 5 is not a solution.
Answer:
D) 5
Step-by-step explanation:
To solve this problem, we must first isolate the variable and simplify the inequality. Isolating the variable means having the variable on one side of an equation or inequality without any other terms?
How do you isolate a variable?
Here's an example.
x+3=18
What can we do to have x on its own side of the equation? Currently, 3 is also with it. If we subtract 3 on both sides, we are leaving the equation with the same answer.
x + 3 - 3= 18 - 3
Combine like terms.
x = 21
That's how you solve for an equation.
Next, an example with division.
3x = 21
How do we solve for x this? Well, we know that 3x = 3 times x. So, to solve for x, we remove the 3. Since its 3 times x, lets divide by 3 on both sides.
[tex]\frac{3x}{3} =\frac{21} {3}[/tex]
Simplify:
3x/3 means 3 times x divided by 3. 3/3 = 1
1x = 21/3
21/3 = 7
x = 7
Now lets get to the problem.
[tex]-4x + 9 \geq -3[/tex]
The first step is to subtract by 9 on both sides so we can work our way to isolating the variable and solving the problem.
[tex]-4x + 9 -9\geq -3 - 9[/tex]
Simplify.
[tex]-4x \geq -12[/tex][tex]-4x \geq -12[/tex]
Now heres the tricky part. To solve for an equation, we must remove -4 from x, or -4 times x. In an equality, which states that:
A [tex]\geq , \leq , > , or < B[/tex]
If you divide or multiply both sides by a negative number, which means the number is less than 0, you must flip the sign!
When you multiply/divide by a negative number or both sides in an equality:
[tex]\leq[/tex] [tex]\geq[/tex]
[tex]\geq[/tex] [tex]\leq[/tex]
> <
< >
So, we currently have:
[tex]-4x \geq -12[/tex]
Divide by -4 on both sides.
[tex]\frac{-4x}{-4} \geq \frac{-12}{-4}[/tex]
Simplify. (Use the rule which states that a negative number multiplied or divided by another negative number equates to a positive number).
[tex]x \geq 3[/tex]
Flip the sign (This is a crucial step!)
[tex]x \leq 3[/tex]
Now, [tex]x \leq 3[/tex] means any number equal to or lower than 3 satisfies the conditions of the inequality.
Is -3 lower than or equal to 3?
Yes; Lower
Is -1 lower than or equal to 3?
Yes;
Is 3 lower than or equal to 3?
Yes; Equal
Is 5 lower than or equal to 3?
No; Greater

Jacob reduced the size of a painting to a width of 3. 2 inches. What would be the new height if the painting was originally 42. 88 inches in width and 33. 5 inches tall?.
Answers
The new height of painting by Jacob will be 2.5 inches.
The ratio and proportion will be used to relate the original and reduced dimensions of painting. The original width and height = 42.88/33.5. Let us assume the new height be x. So, new width and height = 3.2/x. Equating these two fractions -
42.88/33.5 = 3.2/x
Rewriting the equation according to x
x = (3.2 × 33.5) ÷ 42.88
Performing multiplication in numerator
x = 107.2 ÷ 42.88
Performing division on Right Hand Side of the equation
x = 2.5
Thus, the new height will be 2.5 inches.

The value of all the missing angles is in the measure of m∠1 = 88°, m∠2 = 42°, and m∠3 = 113°.
We know that,
Sum of all angles of triangle = 180°.
Therefore, m∠3 + 42° + 25° = 180°.
m∠3 = 180° - 67°
m∠3 = 113°
Vertical angles: Vertical angles are the angles that are opposite to each other when two lines cross.
We know that,
Vertical or opposite angles have equal measures.
So, 42° and m∠2 are vertical or opposite angles.
Therefore, the value of m∠2 = 42°.
Similarly, for m∠3, We know that,
Sum of all angles of triangle = 180°.
∴ ∠1 + ∠2 + 50° = 180°.
=> ∠1 + 42° + 50° = 180°

5,10,20 Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form.
Answers
The given sequence is geometric sequence not arithmetic.
What is arithmetic sequence?An arithmetic sequence is a sequence in which the difference between every two consecutive terms is constant
What is the geometric sequence?A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value. It is found by taking any term in the sequence and dividing it by its preceding term.
Difference between arithmetic and geometric sequence:
An arithmetic sequence has a constant difference between each consecutive pair of terms
while
A geometric sequence has a constant ratio between each pair of consecutive terms.
Here, we have a sequence 5,10,20.
So a₁ = 5, a₂ = 10, a₃ = 20
Difference = a₃- a₂ = 20 - 0 = 10
a₂ - a₁ = 10 - 5 = 5
Since the difference is not constant, therefore the given sequence is not arithmetic.
Now ratio a₃/a₂ = 20/10 =2 and a₂/a₁ = 10/5 =2 which is same which shows the sequence is geometric.
Therefore, the sequence is geometric sequence.

The solutions to the expression x³ + 87 = 7x² + x are given as follows:
–3, 5 + 2i, 5 – 2i.
How to obtain the solutions to the equation?The equation is defined as follows:
x³ + 87 = 7x² + x.
In standard format, it is given by:
x³ - 7x² - x + 87 = 0.
It has one negative solution, hence from the options it is:
x = -3.
The verification is:
(-3)³ - 7(3)² - (-3) + 87 = 0.
Considering the linear factor (x + 3), the function can be written as follows:
x³ - 7x² - x + 87 = (x + 3)(ax² + bx + c).
As the product of a linear function and a quadratic function results in a cubic function.
Expanding the right side of the equality, we have that:
ax³ + (b + 3a)x² + (3b + c)x + 3c = x³ - 7x² - x + 87.
Hence the coefficients of the quadratic equation are given as follows:
a = 1.b + 3a = -7 -> b = -10.c = 87/3 = 29.Hence the equation is:
x² - 10x + 29 = 0.
And the solutions, using a quadratic equation calculator, are given as follows:
x = 5 + 2i.x = 5 - 2i.Which means that the third option is correct.
