Answer:
your profit is Double the price that you bought the kits
Step-by-step explanation:
x= cost of kit
you buy it x/2
x/2 + 4.5 .... (1)
x + x/2 +4.5 .... (2)
let x = 40
40/2 + 4.5 = 24.5
40 + 40/2 + 4.5 = 64.5
64.5 - 24.5 = 40
so
you buy it in x/2 = 40/2 = 20
and sell it in x = 40
40/20 = 2
your profit is Double the price that you bought the kits
The profit is Double the price that you bought the kits.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We have been given that the cost of the kits on sale for 50% of the original price, plus a shipping fee of $4.50 per kit.
Let x be the cost of kit.
Therefore,
x/2 + 4.5 .... (1)
x + x/2 +4.5 .... (2)
let x = 40
40/2 + 4.5 = 24.5
40 + 40/2 + 4.5 = 64.5
64.5 - 24.5 = 40
Therefore, buy it in x/2 = 40/2 = 20
and sell it in x = 40
40/20 = 2
Hence, the profit is Double the price that you bought the kits.

Question 6 The mineral content of a particular brand of supplement pills is normally distributed with mean 490 mg and variance of 400. What is the probability that a randomly selected pill contains at least 500 mg of minerals
Answer:
0.3085 = 30.85% probability that a randomly selected pill contains at least 500 mg of minerals
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean 490 mg and variance of 400.
This means that [tex]\mu = 490, \sigma = \sqrt{400} = 20[/tex]
What is the probability that a randomly selected pill contains at least 500 mg of minerals?
This is 1 subtracted by the p-value of Z when X = 500. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{500 - 490}{20}[/tex]
[tex]Z = 0.5[/tex]
[tex]Z = 0.5[/tex] has a p-value of 0.6915.
1 - 0.6915 = 0.3085
0.3085 = 30.85% probability that a randomly selected pill contains at least 500 mg of minerals
The probability is 0.3085.
Let X=the amount of minerals.
We have to find P(X≥500).
Mean = 490.
Standard deviation = [tex]\sqrt{400}=20[/tex].
z score of 500 is = [tex]\frac{500-490}{20 } =0.5[/tex].
So, P(X≥500) = P(z≥0.5) = 1 - P(z<0.5) = 1-0.6915=0.3085.

What is the value of this expression? 6 (24 ÷ 3) - 2
Answer:
46
Step-by-step explanation:
Follow the order of operations
The value of the expression 6(24 ÷ 3) - 2 is 46.
How to solve the expressionTo evaluate the expression 6(24 ÷ 3) - 2, we follow the order of operations, which is commonly referred to as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).
First, we simplify the expression inside the parentheses:
24 ÷ 3 = 8
Now we substitute the result back into the original expression:
6(8) - 2
Next, we perform the multiplication:
6 * 8 = 48
Finally, we perform the subtraction:
48 - 2 = 46
Therefore, the value of the expression 6(24 ÷ 3) - 2 is 46.

Rishan is building a number 3091 using Place-value blocks. There are no thousands block. How many hundreds blocks can he use instead?
Given:
The number is 3091.
To find:
The number of hundreds blocks if there are no thousands block.
Solution:
The given number is 3091.
It can be written as:
[tex]3091=3000+0+90+1[/tex]
[tex]3091=3\times 1000+0\times 100+9\times 10+1\times 1[/tex]
[tex]3091=3\ Thousands+0\ Hundreds+90\ Tens+1\ Ones[/tex]
There are no thousands block. So,
[tex]3000=30\times 100[/tex]
[tex]3000=30\ Hundreds[/tex]
Therefore, the number of hundreds blocks in 3091 is 30.

y ≈ 61
Step-by-step explanation:
Using the Sine rule in the triangle
[tex]\frac{y}{sin117}[/tex] = [tex]\frac{21}{sin18}[/tex] ( cross- multiply )
y × sin18° = 21 × sin117° ( divide both sides by sin18° )

4. Given point A (3, 8) and point B (-5, 1). Find the following:
a.) The coordinates of the midpoint of segment AB. Write your answer in this form: (x, y) (7 points)
b.) Using the distance formula, find the length of segment AB. Round to the nearest hundredth. (7 points)
c.) Find the slope of segment AB. (if your answer is a fraction, use the "/" symbol) (7 points)
Answer:
a) (-1,4.5)
b)10.63 units
c)7/8
Step-by-step explanation:
a) To find this, we use the midpoint formula
(x,y) = (x1 + x2)/2 , (y1 + y2)/2
(x1,y1) = (3,8)
(x2,y2) = (-5,1)
(x,y) = (3 -5)/2 , (8 + 1)/2 = (-1, 4.5)
b) To calculate the distance D between two points, we use the formula;
D = √(x2-x1)^2 + (y2-y1)^2
D = √(-5-3)^2 + (1-8)^2
D = √(-8)^2 + (-7)^2
D = √64 + 49
D = √113
D = 10.63 units
C) We use the slope formula here
m = (y2-y1)/(x2-x1)
m = (1-8)/(-5-3) = -7/-8 = 7/8
What type of quadrilateral has the vertices A(3 , 6), B(3 , 3), C(6 , 3),and D(6 , 6)
Answer:
It is a square.
Step-by-step explanation:Background:
With this, lets find the distance between each of the shape's points, in order to find which shape it is.
Here's the distance formula, its a bit overkill for what you're doing right now, but it may help you with questions later on.
d=√(x2−x1)2+(y2−y1)2
Process:
So with this, compare the distance between each of the points. With Point A, it is (3, 6) with Point B it is (3,3). The change between these two points is down 3.
Next, with Point B (3,3) and Point C (6,3). The change between these two points is right 3.
Then, with Point C (6,3) and Point D (6,6). The change between these two points is up 3.
Last, with Point D (6,6) and Point A (3,6). The change between these two points is left 3.
Reasoning:
From this, we can see that all of the distance lengths are 3 units and that each of them create 90 degree angle turns*.
*You can find this by noting that the total amount of a rotation is 360 degrees, so when you change walking from up to the right, you are turning 90 degrees to do so.
Answer:
With this information in mind, it can be named a square given the definition of square:
"A regular quadrilateral, which means that it has four equal sides and four equal angles."

Step-by-step explanation:
The degree of a polynomial is its highest exponent value: in this case, thats just two!
Answer:
degree 2
Step-by-step explanation:
The degree of a polynomial is determined by the largest value of the exponent attached to the variable.
f(x) = 2x² - 5x + 6 ← has the term 2x² with exponent 2 ( largest ), then
