James mixes 7 cups of water with 2 scoops of lemonade mix. Charlie needs
to create a much larger batch of lemonade, so he mixes 25 cups of water with
10 scoops of mix.
Whose lemonade is stronger? Explain your reasoning,
The correct answer is Charlie's lemonade
Explanation:
The quantity of lemon vs sugar depends on the ratio each boy used. In the case of James, the ratio of water to the lemonade mix was 7:2. This means he 2 added scoops of lemonade for every 7 cups of water. On the other hand, the ratio of Charlie was 25: 10, which can be simplified as 5: 2 by dividing both numbers by a common divisor (5). This shows, Charlie's lemonade is stronger because he added the same lemonade mix in a lower amount of water, which would make the lemonade have a stronger flavor.
Jim and Lou compare two numbers. Jim thinks eight-hundredths is ten times larger than eight thousandths. Lou thinks eight-thousandths is ten times larger than eight hundredths. Who is correct?
Jim or Lou
Answer:
Lou is correct
Step-by-step explanation:
Let's analyze each statement.
First statement says:
"Jim thinks eight - hundredths is ten times larger than eight - thousandths.
What he is saying is that ten times of eight thousandths is lesser than eight - hundredths.
Now, expressing this in numbers gives:
800/8000 = 10
By inspection, we can see that 800/8000 is equal to 1/10 and not 10 that is given.
Thus, the statement is not correct.
Second statement says;
Lou thinks eight - thousandths is ten times larger than eight hundredths.
What he is saying is that ten times of eight hundredths is smaller than eight thousandths. Expressing this in numbers gives;
8,000/800 = 10
By inspection, 8000/800 gives 10 which corresponds to what is given.
Thus, the statement is correct.
Thus, Lou is correct.

A. )75,000 + 4,800n = 80,000 + 3,900n
B.)75,000n + 4,800 = 80,000n + 3,900
C)75,000n + 4,800n = 80,000n + 3,900n
D)75,000n + 4,800 = 80,000 + 3,900n
Answer:
Step-by-step explanation:
C
The required expression that represents the number of years it will take Catherine to earn the same salary as Lola is 75,000n + 4,800n = 80,000n + 3,900n. option C is correct.
Given that,
Catherine earns a yearly salary of $75,000. Lola earns a yearly salary of $80,000. Catherine will receive a salary increase of $4,800 per year, and Lola will receive a salary increase of $3,900 per year.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Let the number of years be n
Catherine's income after n year = 75000 + 4800n

2.A production process manufactures items with weights that are normally distributed with mean 10 pounds and standard deviation 0.1. An item is considered to be defective if its weight is less than 9.8 pounds or greater than 10.2 pounds. Suppose that these items are currently produced in batches of 1000 units. a.Find the probability that at most 5% of the items in a given batch will be defective b.Find the probability that at least 85% of these items in a given batch will be acceptable.
Answer:
Step-by-step explanation:
Given that:
population mean = 10
standard deviation = 0.1
sample mean = 9.8 < x > 10.2
The z score can be computed as:
[tex]z = \dfrac{\bar x - \mu}{\sigma}[/tex]
if x > 10.2
[tex]z = \dfrac{10.2- 10}{0.1}[/tex]
[tex]z = \dfrac{0.2}{0.1}[/tex]
z = 2
If x < 9.8
[tex]z = \dfrac{9.8- 10}{0.1}[/tex]
[tex]z = \dfrac{-0.2}{0.1}[/tex]
z = -2
The p-value = P (z ≤ 2) + P (z ≥ 2)
The p-value = P (z ≤ 2) + ( 1 - P (z ≥ 2)
p-value = 0.022750 +(1 - 0.97725)
p-value = 0.022750 + 0.022750
p-value = 0.0455
Therefore; the probability of defectives = 4.55%
the probability of acceptable = 1 - the probability of defectives
the probability of acceptable = 1 - 0.0455
the probability of acceptable = 0.9545
the probability of acceptable = 95.45%
4.55% are defective or 95.45% is acceptable.
sampling distribution of proportions:
sample size n=1000
p = 0.0455
The z - score for this distribution at most 5% of the items is;
[tex]z = \dfrac{0.05 - 0.0455}{\sqrt{\dfrac{0.0455\times 0.9545}{1000}}}[/tex]
[tex]z = \dfrac{0.0045}{\sqrt{\dfrac{0.04342975}{1000}}}[/tex]
[tex]z = \dfrac{0.0045}{\sqrt{4.342975 \times 10^{-5}}}[/tex]
z = 0.6828
The p-value = P(z ≤ 0.6828)
From the z tables
p-value = 0.7526
Thus, the probability that at most 5% of the items in a given batch will be defective = 0.7526
The z - score for this distribution for at least 85% of the items is;
[tex]z = \dfrac{0.85 - 0.9545}{\sqrt{\dfrac{0.0455\times 0.9545}{1000}}}[/tex]
[tex]z = \dfrac{-0.1045}{\sqrt{\dfrac{0.04342975}{1000}}}[/tex]
z = −15.86
p-value = P(z ≥ -15.86)
p-value = 1 - P(z < -15.86)
p-value = 1 - 0
p-value = 1
Thus, the probability that at least 85% of these items in a given batch will be acceptable = 1
a. 0.7526
b. 1
Given that:
[tex]\sigma = 0.1\\\mu = 10\\[/tex]
It is given that item is acceptable if 9.8 < X < 10.2
Calculating standard variate value for :
1. x = 9.8:
[tex]z = \dfrac{x - \mu}{\sigma}\\[/tex]
z = -2
2. x= 10.2
[tex]z = \dfrac{x - \mu}{\sigma}\\[/tex]
z = 2
Now we can convert P( 9.8 < X < 10.2) to P(-2 < Z < 2).
Calculating
P(-2 < Z < 2) = P(Z <2) - P(Z < - 2)
= 0.9772 - 0.0227 (refer these values from z score table)
= 0.9545
Thus, the probability that an item from that population if randomly selected, it has 0.9545 probability to be acceptable.
And thus probability of an item to be defective is 1 - 0.9545 = 0.0455.
The batch size is 1000 unit.
The probability that at most 5% items are defective is calculated by z scores:
[tex]z = \dfrac{0.05-0.045}{\sqrt[2]{\dfrac{0.0455\times 0.9545}{1000}}}[/tex]
or
z = 0.6828
P( at most 5% defective) = [tex]P(Z \leq 0.6828)[/tex]
= 0.7526 ( from z score table).
[tex]z = \dfrac{0.85-0.9545}{\sqrt[2]{\dfrac{0.0455\times 0.9545}{1000}}}[/tex]
or
z = -15.8
and thus
P( at least 85% acceptable ) = P(Z >= -15.8) = 1- P(Z < -15.8)
P( at least 85% acceptable ) = 1 - 0 = 1
The z score tables give p values.

Answer:
100Step-by-step explanation:
Let the number we are looking for be x. If Jack divided 1,826.5 by the number to get a quotient of 18.265, to get the number we will solve the equation;
1,826.5/x = 18.265
Cross multiply
1826.5 = 18.265x
Divide both sides by 18.265
18.265x = 1826.5
18.265x/18.625 = 1826.5/18.625
x = 100
Hence Jack divide 1,826.5 by 100 to get a quotient of 18.265
Here, we are required to find the number Jack divide 1,826.5 by to get a quotient of 18,265?
The number is 100
First, it is important to form an expression from the data given;
Let the no. which Jack divided 1,826.5 by be x.
The result of the division yields a quotient of 18.265.
From the statements above;
1,826.5/x = 18.265
Therefore, 1826.5 = 18.265x.
Therefore, x = 1826.5/18.265 = 100.
Therefore,
the number which Jack divided 1,826.5 by to get a quotient of 18.265 is x = 100.

What is Modulus Function?
Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.
It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.
The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:
If x is positive, then f(x) = x
If x = 0, then f(x) = 0
If x < 0, then f(x) = -x
Given data ,
Let the equation be represented as A
Now , the value of A is
| x + 5 | = -9 be equation (1)
On simplifying the equation , we get
The modulus function always returns a positive value
So , when x = 4
Substitute the value of x = 4 in the equation , we get
| 4 + 5 | = -9
| 9 | = -9
And , 9 ≠ -9
Therefore , the equation is False
Hence , the solution is false and the modulus function returns a positive value

Pls ANSWER FAST!!
Answer:
28°Step-by-step explanation:
Find the attachment in the diagram. According to the diagram, the sum of angle on the straight line AOB is 180°. Also the < AOD is equal to <COB (oppositely directed angle)
From the diagram;
m∠COE+m∠EOF+m∠FOB = <COB
Given
m<AOD = 152
m∠COE = 3x
m∠EOF = x
m∠FOB = x+ 12
Since < AOD = < COB, the expression above becomes;
m∠COE+m∠EOF+m∠FOB = m<AOD
Next is to substitute the given parameters into the formula above to get x;
3x+x+x+12 = 152
5x+12 = 152
subtract 12 from both sides of the equation
5x+12-12 = 152-12
5x = 140
divide both sides by 5;
5x/5 = 140/5
x = 28°
