What is the y intercept and slope hurry please
Answers
From the given graph , we see that it passes through the point (0,-1) .
Hence the y intercept is -1 .→ y intercept = -1
For finding slope , take another point as (1,3) . Now using the points (1,3) and (0,-1) we can find out the slope as ,
→ m = y2 - y1 / x2 - x1
Substituting the respective values,
→ m = 3 -(-1)/1-0
→ m = 3+1/1
→ m = 4/1
→ m = 4
Hence the slope of the line is 4 and its y intercept is -1 .
Parallelogram ABCD is a rhombus. Side BC= 5 cm and segment AO = 3.8 cm. what is the area of ABCD
Answers
The area of a shape is the amount of space it occupies
The area of the rhombus is 24.7 square inches
How to determine the area of the rhombusStart by calculating the length BO using the following Pythagoras theorem
[tex]BC^2 = AO^2 + BO^2[/tex]
So, we have:
[tex]5^2 = 3.8^2 + BO^2[/tex]
Evaluate the exponents
[tex]25 = 14.44 + BO^2[/tex]
Collect like terms
[tex]BO^2 = 25 - 14.44[/tex]
[tex]BO^2 = 10.56[/tex]
Take the square roots
[tex]BO = 3.25[/tex]
The area of the rhombus is then calculated as:
[tex]Area = \frac{2BO * 2AO}{2}[/tex]
This gives
[tex]Area = \frac{2 * 3.25 * 2 * 3.8}{2}[/tex]
[tex]Area = 24.7[/tex]
Hence, the area of the rhombus is 24.7 square inches

A box of candy weighs 340. 23 grams and costs $18. 99. If 1 gram is approximately 0. 03527 ounces, what is the unit price per ounce of the candy? a. $0. 53 b. $0. 67 c. $1. 58 d. $1. 97.
Answers
Unit price per ounce of the candy of 340.23 grams is $1.58
What is ounce and gram ?Ounce and gram are two different unit of mass and relation between them is 1 gram = 0.03527 ounces .
In the question it is given that weight of candy is 340.23 grams
And it costs $18.99
Now we can covert grams to ounces as
[tex]1 \text{gram}= \ 0.03527 \text{ounces}\\[/tex]
Hence
[tex]340.23 \text{gram}= \ 340.23\times 0.03527 \text{ounces}\\\\\\340.23 \text{gram}=11.99 \ \text{ounces}\\[/tex]
Now 11.99 ounces of candy cost $18.99
So 1 ounce of candy cost 18.99/11.99= $1.58
Unit price per ounce of the candy of 340.23 grams is $1.58

75% of what number is 15? make it so clear pls pls
Answers
20 is the answer.
Step-by-step explanation:
Take a look at the given question,
"75% of what number is 15"
Let's substitute this "what number" as "x"
[tex]75[/tex]%[tex] \times x = 15[/tex]
[tex]→x = \frac{15}{75 \: percent} [/tex]
[tex]→x = \frac{15}{ \frac{75}{100} } [/tex]
[tex]→x = \frac{15}{0.75} [/tex]
To make the denominator as positive for making calculations more easy, we get,
[tex]x = \frac{15 \times 100}{0.75 \times 100} [/tex]
[tex]→x = \frac{1500}{75} [/tex]
Now after doing the division, we get,
[tex]x = 20[/tex]
Hence, 75% of 20 is 15.

E. [tex]\frac{-y}{x^2}[/tex]
Answers
Answer:
A) [tex]\frac{d^2y}{dx^2}=\frac{2y}{x^2}[/tex]
Step-by-step explanation:
Use implicit differentiation to find dy/dx
[tex]x^2y^2=1\\\\\frac{d}{dx}(x^2y^2)=\frac{d}{dx}(1)\\ \\x^2(\frac{d}{dx}y^2)+(\frac{d}{dx}(x^2))y^2 =0\\\\2yx^2\frac{dy}{dx}+2xy^2=0\\\\2xy(x\frac{dy}{dx}+y)=0\\ \\x\frac{dy}{dx}+y=0\\ \\x\frac{dy}{dx}=-y\\ \\\frac{dy}{dx}=-\frac{y}{x}[/tex]
Determine d²y/dx² using dy/dx
[tex]\frac{dy}{dx}=\frac{-y}{x}\\ \\ \frac{d^2y}{dx^2}=\frac{(x)[\frac{d}{dx}(-y)]-(-y)[\frac{d}{dx}(x)] }{x^2}\\ \\ \frac{d^2y}{dx^2}=\frac{-x\frac{dy}{dx}+y}{x^2}\\ \\ \frac{d^2y}{dx^2}=\frac{-x(\frac{-y}{x})+y}{x^2}\\\\ \frac{d^2y}{dx^2}=\frac{-(-y)+y}{x^2}\\\\ \frac{d^2y}{dx^2}=\frac{y+y}{x^2}\\\\ \frac{d^2y}{dx^2}=\frac{2y}{x^2}[/tex]
Helpful tips
When doing implicit differentiation, make sure to treat "y" as a constant and write dy/dx next to the y-term because it's differentiated with respect to xThe product rule is [tex]\frac{d}{dx}[f(x)g(x)]=f(x)[\frac{d}{dx}g(x)]+[\frac{d}{dx}f(x)]g(x)[/tex]The quotient rule is [tex]\frac{d}{dx}[\frac{f(x)}{g(x)}]=\frac{f(x)[\frac{d}{dx}g(x)]-g(x)[\frac{d}{dx}f(x)]}{(g(x))^2}[/tex][tex]\frac{dy}{dx}[/tex] represents the first derivative of y with respect to x and [tex]\frac{d^2y}{dx^2}[/tex] represents the second derivative of y with respect to xLet me know if you have any more questions!

A student is about to take a true-false, 5-question quiz, with absolutely no knowledge of the subject. So, the student flips a coin to determine their response to each question. If you let the random variable X = "a number of correct answers on the quiz," what is the correct histogram?
Answers are from 1-4, and they are all in order.
Answers
Using the binomial distribution, considering the probability of each event, the correct histogram is the fourth one.
For each question, there are only two possible outcomes, either the student guesses the correct answer, or not. The probability of guessing the correct answer on a question is independent of any other question, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
There are questions, hence n = 5.They are true-false questions, that is, they have one correct option out of 2, hence p = 0.5.Then, the probabilities are as follows:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{5,0}.(0.5)^{0}.(0.5)^{5} = 0.03125[/tex]
[tex]P(X = 1) = C_{5,1}.(0.5)^{1}.(0.5)^{4} = 0.15625[/tex]
[tex]P(X = 2) = C_{5,2}.(0.5)^{2}.(0.5)^{3} = 0.3125[/tex]
[tex]P(X = 3) = C_{5,3}.(0.5)^{3}.(0.5)^{2} = 0.3125[/tex]
[tex]P(X = 4) = C_{5,4}.(0.5)^{4}.(0.5)^{1} = 0.15625[/tex]
[tex]P(X = 5) = C_{5,5}.(0.5)^{5}.(0.5)^{0} = 0.03125[/tex]
Hence the fourth histogram is correct.
