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.
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

Evaluate the expression z2 - 6 if z = 4 The solution is:
Answer:
4 x 2 - 6

Step-by-step explanation:
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.
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.

There are 110 sixth-grade students in a Florida
middle school. 40% of the students enjoy playing
video games on the weekends. Using the percent
as a rate per 100, how many students enjoy
playing video games?
Answer:
44 students play video games
Step-by-step explanation:
110*0.40 = 44
i hope this helps! have a wonderful rest of ur day :)
Answer:
40/100
Step-by-step explanation:
40% of 110 is 44 so we make this a fraction 44/110 and then simplify to get 2/5 and after that we know that 2/5 is also 40/100, meaning 40 out of 100 students like video games.
What is the y intercept and slope hurry please
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 .

75% of what number is 15? make it so clear pls pls
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.
Find [tex]\frac{d^2y}{dx^2}[/tex] if [tex]x^2y^2=1[/tex]

B. 0
C. [tex]\frac{y}{x}[/tex]
D. [tex]\frac{-y}{x}[/tex]
E. [tex]\frac{-y}{x^2}[/tex]
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!

5% of the people came from Scotland.
30% of the people came from Wales.
How many more people came from Wales than from Scotland?
Answer:
75
Step-by-step explanation:
0.3*300=90
0.05*300=15
90-15=75
Answer:
ok so we want to find out 30% of 300 is
so first lets turn it into its decmil form by multiplying by 0.01 so
30*0.01=0.3
then lets multiply that by 300 so
300*0.3=90
90 people were from whales
15 people from scotland

A farmer owns a total of 8 4/5 acres of land. The land is separated into 4
equally sized sections. How many acres are in each section?
Explanation:
The mixed number 8 & 4/5 consists of the whole part 8 and the fractional part 4/5.
Divide the whole part 8 into 4 equal pieces
8/4 = 2
This means 2 is part of the final answer.
Also, divide the 4/5 into 4 equal pieces as well. This is the same as multiplying by 1/4
(1/4)*(4/5) = 1/5
Overall, the size of each section is 2 & 1/5 acres

What is the slope of the line that passes through (-4,2) and (6,-8)
Answer:
y = x + -2
Step-by-step explanation:
I know you're probably asleep but here's the answer. And I'm 14 years old, so I might be young and undereducated.
(-4,2) and (6,-8)
-8-2 = -10
6 -(-4) = 10 (-10/10 = -1)
-8 = 6(-1) + b
-8 = -6 + b
-2 = b
