Answer: 68 1/18
Step-by-step explanation:
Area of the large rectangle:
11 1/3 x 7 = 79 1/3
Area of tiled floor:
4 5/6 x 2 1/3 = 11 5/18
79 1/3 - 11 5/18 = 68 1/18
Answer:
68 1/18
Step-by-step explanation:
7 x 11 1/3 = 79 1/3
4 5/6 x 2 1/3 = 11 5/18
79 1/3 - 11 5/18 = 68 1/8
p+h= 43
4.5p+12h=276
9514 1404 393
Answer:
(p, h) = (32, 11)
Step-by-step explanation:
We can write an expression for p using the first equation, then substitute that into the second equation.
4.5(43-h) +12h = 276 . . . . substitute for p
193.5 +7.5h = 276 . . . . . . eliminate parentheses
7.5h = 82.5 . . . . . . . . . . . . subtract 193.5
h = 82.5/7.5 = 11 . . . . . . . . divide by the coefficient of h
p = 43 -11 = 32
The solution is (p, h) = (32, 11).
If 8 people invest each in a stamp collection and after a year the collection is worth $3,800, how much did each person lose? show work
This question is incomplete, the complete question is;
If 8 people invest $500 each in a stamp collection and after a year the collection is worth $3,800, how much did each person lose? show work
Answer:
Each person lost $25
Step-by-step explanation:
Given the data in the question;
Number people that invested = 8
Amount each invested = $500
worth after a year the collection = $3,800
Now, the amount each person lost will be;
[tex]Lost_{each-person[/tex] = Total loss / total number of persons
[tex]Lost_{each-person[/tex] = [ ( 500 × 8 ) - 3800 ] / 8
[tex]Lost_{each-person[/tex] = [ 4000 - 3800 ] / 8
[tex]Lost_{each-person[/tex] = 200 / 8
[tex]Lost_{each-person[/tex] = 25
Therefore, each person lost $25

Which set is a proper subset of the counting numbers?
{−1,0,1}
{5}
{0}
{1,2,3,…}
Answer:
{5}
Step-by-step explanation:
Set of counting numbers:
Set of numbers you count with, starting from 1. So
C = {1,2,3,4,5,....}
Proper subset of a set:
A proper subset of a set A is a subset B that is not equal to A, that is, all elements of B are in A but A has at least one element that is not in B.
In this question:
The set of counting numbers is C = {1,2,3,4,5,....}
Among the options, {-1,0,1} and {0} are not subsets of C, as they contain elements that are not in C, while {1,2,3,...} is not a proper subset, as it is equals to C. So the correct answer is {5}.

Step-by-step explanation:
The length, l, that a spring is stretched varies directly as the amount of force, F, applied to the end of the spring. When a force of 10 pounds is applied to a spring, it stretches 3 inches. How much will the same spring stretch if the force is increased to 15 pounds?
A.
8 inches
B.
7.5 inches
C.
4.5 inches
D.
2 inches
Answer:
C. 4.5 inches
Step-by-step explanation:
Given the following data;
Force, F = 10 pounds
Extension, e = 3 inches
First of all, we would determine the spring constant (k) using the following formula;
Force = spring constant * extension
10 = spring constant * 3
Spring constant = 10/3
Spring constant = 3.33 pounds per inches.
Next, we would find the extension of the spring when a force of 15 pounds is applied;
F = ke
15 = 3.33 * e
Extension, e = 15/3.33
Extension, e = 4.5 inches.

The sail of a boat is in the shape of a right triangle. Which expression shows the length, in meters, of the sail?
The sail of a boat is a right triangle with an acute angle at the tip equal to 50 degrees and the side of the sail which is the hypotenuse to the right triangle is 7 meters long.
7(tan 50°)
7(sin 50°)
tangent 50 degrees over 7
sine 50 degrees over 7
Answer:
The answer is 7(tan 50°)
Step-by-step explanation:
So first you need to find which formula you will be using to do this you need to find if you're talking about the hypotenuse, opposite, or adjacent.
The side that measures 7 meters would be the adjacent because its right next to the angle and its not the hypotenuse because its not the largest side
The side which we do not know the length to will be the opposite side because it is opposite from where the angle is.
There are 3 formulas:
sin A = Opposite side/Hypotenuse = BC/AB
cos A = Adjacent side/Hypotenuse = AC/AB
tan A = Opposite side/Adjacent side = BC/AC
There is one formula that has Opposite and Adjacent which is tangent so thats the formula you'll use
Next you plug in the values that you have so your formula will look like this:
Tan 50° = x/7
A will always be where you plug in the angle and then you plug in the information according to what side it is
Every time that x is the numerator you will just multiply both sides by the denominator which gives you:
7(tan 50°)
Which is your answer :))
Answer:
tangent 50 degrees over 7

Tanya is playing Pokemon Go, and searching for a Snorlax. The game is programmed such that pokemon are generated randomly, and there is a 5% chance that a Snorlax will appear. Tanya will search Mill Creek park until she captures 312 random pokemon. Consider the proportion in her sample that will be Snorlax. As we have learned, the sample proportion is a random quantity.
Required:
a. What type of random variable can we use to approximate the sample proportion?
b. What is the mean of the sample proportion?
c. What is the standard deviation of the sample proportion?
d. What is the approximate probability that more than 10% of her sample will be Snorlaxes?
Answer:
a) Approximately normal variable.
b) 0.05.
c) 0.0123
d) Approximately 0% probability that more than 10% of her sample will be Snorlaxes
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
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.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
5% chance that a Snorlax will appear. Tanya will search Mill Creek park until she captures 312 random pokemon.
This means that [tex]p = 0.05, n = 312[/tex]
a. What type of random variable can we use to approximate the sample proportion?
By the Central Limit Theorem, an approximately normal variable.
b. What is the mean of the sample proportion?
[tex]\mu = p = 0.05[/tex]
The mean is 0.05.
c. What is the standard deviation of the sample proportion?
[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.05*0.95}{312}} = 0.0123[/tex]
d. What is the approximate probability that more than 10% of her sample will be Snorlaxes?
This is 1 subtracted by the pvalue of Z when X = 0.1. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.1 - 0.05}{0.0123}[/tex]
[tex]Z = 4.05[/tex]
[tex]Z = 4.05[/tex] has a pvalue of approximately 1
1 - 1 = 0
Approximately 0% probability that more than 10% of her sample will be Snorlaxes
The equation of the regression line is Y = 76 + 2x. Which of the
following choices describes the slope?
We can see here that the choice that describes the slope is: D. None of the choices are correct.
What is slope?In mathematics, slope refers to the measure of the steepness or incline of a line. It quantifies how much a line rises or falls as it moves horizontally from one point to another. Slope is often denoted by the letter "m" and can be calculated using the formula:
slope (m) = (change in y-coordinates) / (change in x-coordinates)
Slope is a fundamental concept in algebra and geometry and has various applications. It helps in determining the direction, steepness, rate of change, and relationships between variables. Slope is used in analyzing lines, calculating rates, graphing linear equations, finding equations of lines, and solving many real-life problems involving lines and gradients.
