Joyce works at Fortunato's Furniture. She is paid on commission. She receives 10% of her first $1,200 in sales and 15% of the balance of her sales. Last week she earned $950. What was the value of the furniture she sold? show your work.
The total value of the furniture sold by Joyce last week is A = $ 6,733.33
Given data ,
Let's call the value of the furniture Joyce sold "x".
She receives 10% commission on the first $1,200 of sales, which is $120:
Commission on first $1,200 = 0.1 * 1200 = 120
The remaining sales that she earns commission on is the difference between the total value of the furniture sold and the first $1,200:
Remaining sales = x - 1200
She earns 15% commission on the remaining sales, which is 0.15 times the remaining sales:
Commission on remaining sales = 0.15 * (x - 1200)
Her total earnings from commission last week was $950. So we can write an equation:
Commission on first $1,200 + Commission on remaining sales = $950
Substituting the expressions we found for the two commissions, we get:
120 + 0.15(x - 1200) = 950
120 + 0.15x - 180 = 950
On simplifying the equation , we get
0.15x - 60 = 950
0.15x = 1010
x = 6,733.33
Hence , the value of the furniture Joyce sold last week was $6,733.33

Two drivers, Alison and Kevin, are participating in a race. Beginning from a standing start, they each proceed with a constant acceleration. Alison covers the last one seventh 1 7 of the distance in 33 seconds, whereas Kevin covers the last one third 1 3 of the distance in 77 seconds. Who wins and by how much time?
Answer:
Step-by-step explanation:
Acceleration is the rate of change of velocity. When acceleration is high, it means that the velocity is not changing. Since they ran at a constant acceleration, it mean that their velocities didn't change throughout.
If Alison covers the last one seventh of the distance in 33 seconds, it means that the distance covered in 33 seconds is
1/7 = 0.14
Velocity = distance/time
Velocity of Alison = 0.14/33 = 0.004242
If Kevin covers the last one third of the distance in 77 seconds, it means that the distance covered in 77 seconds is
1/3 = 0.33
Velocity of kelvin = 0.33/77 = 0.004286 m/s
We can see that Kelvin has a greater speed. So kelvin had covered Alison's, distance, the time he would have spent is
Time = distance/velocity
Time = 0.14/0.004286 = 32.66
The time difference would have been 33 - 32.66 = 0.34 seconds
Kelvin won by 0.34 seconds

The length of ON for the intersecting secants is derived to be equal to 14
What is the intersecting secant theoremThe intersecting secant theorem, also known as the secant-secant theorem, states that when two secant lines intersect outside a circle, the product of the length of one secant segment and its external segment is equal to the product of the length of the other secant segment and its external segment.
MK × KL = MO × MN
note that KL = (ON - 3) so;
[13 + (ON - 3)] × 13 = (12 + ON) × 12
13(10 + ON) = 144 + 12ON
130 + 13ON = 144 + 12ON
13ON - 12ON = 144 - 130 {collect like terms}
ON = 14
Therefore, the length of ON for the intersecting secants is derived to be equal to 14

Putting y=(1–2x)/5 from eqn. (1)

or x^2– x - 6=0

1. Define the following: Odds ratio Relative risk 2. Describe how to calculate the Odds ratio and provde the formula. 3. Describe how to calculate the Relative Risk and provide the formula.
Answer and Explanation:
Odds ratio is the odds that an outcome would happen given a level of exposure in comparison to the occurrence of that outcome without exposure. Odds ratio is calculated by dividing odds of event occurring with exposure(the first group) by odds of event(usually disease) occurring without exposure. Odds is different from probability(denoted p/1-p). While probability is the number of favorable events divided by total number of events, odds is number of favorable events/number of unfavorable events.
Relative risk, also measuring relationship between exposure and outcome, is the ratio of the probability that an outcome would occur without exposure and probability that an outcome would occur with exposure.

formula for collinear vectors
Answer:
Condition of vectors collinearity 1. Two vectors a and b are collinear if there exists a number n such that
a = n · b
Condition of vectors collinearity 2. Two vectors are collinear if relations of their coordinates are equal.
N.B. Condition 2 is not valid if one of the components of the vector is zero.
Condition of vectors collinearity 3. Two vectors are collinear if their cross product is equal to the zero vector.
N.B. Condition 3 applies only to three-dimensional (spatial) problems.
The proof of the condition of collinearity 3
Let there are two collinear vectors a = {ax; ay; az} and b = {nax; nay; naz}. We find their cross product
a × b = i j k = i (aybz - azby) - j (axbz - azbx) + k (axby - aybx) =
ax ay az
bx by bz
= i (aynaz - aznay) - j (axnaz - aznax) + k (axnay - aynax) = 0i + 0j + 0k = 0

The steps which you would take to determine if these figures are similar include the following:

What is a dilation?In Mathematics and Geometry, a dilation is a type of transformation which typically transforms the dimension (size) or side lengths of a geometric object, without affecting its shape.
Therefore, the dimension or side lengths of the dilated geometric object would be stretched or compressed (shrunk) depending on the scale factor that is applied.
By critically observing the graph representing polygon ABCD, we can logically deduce that a sequence of transformations that would polygon ABCD (pre-image) onto polygon A"B"C"D" (image) is a dilation by a scale factor of 1/2 and a reflection of intermediate image.

The critical value, given the sample size of 5 and the confidence level of 99. 0 percent would be 16. 812.
How to find the critical value ?The critical values for the chi-squared (χ^2) distribution depend on the degree of freedom and the level of significance.
The degree of freedom for a chi-squared distribution typically equals the sample size minus 1 so the degrees of freedom here is:
