A hospital needs 80 liters of a 12% solution of disinfectant. This solution is to be prepared from a 33% solution and a 5% solution. How many liters of each should be mixed to obtain this 12% solution? There are different ways to solve this problem, but using a system of equations is the simplest way
Answer: 20 L of 33% solution and 60 L of 5% solution should be mixed
Step-by-step explanation:
0.33x + 0.05(80-x) = 0.12*80
0.33x + 4-0.05x = 9.6
0.33x - 0.05x = 9.6-4
0.28x = 5.6
x = 5.6/0.28
x = 20 L of 33% solution should be used
80-20 = 60 L of 5% solution should be used
Proof:
0.33*20 + 0.05*60 = 0.12*80
6.6 + 3 = 9.6
9.6 = 9.6

Answer:
y = x/2
Step-by-step explanation:
y = -x has a negative slope so cross this one out.
y = 2x has a steeper slope that would be above the black line so cross this one out
y = 0.001x has a slope that acends very slowly so cross this one out.
y = x/2 is the best match.
Some terminology:
⇒what is the slope
⇒ is the steepness of the line
⇒calculated by dividing the rise over the run
⇒ rise is the change in the y-direction
⇒ run is the change in the x-direction
⇒look at the diagram I attached
⇒ how to find the slope in a linear equation
⇒look to the coefficient of the 'x' variable
⇒ that is the slope
Ex. For the line y = x, the slope is 1
⇒A line with a positive slope rises from left to right while a line with a negative slope falls from left to right.
Ex. y=x has a positive slope and thus is rising
We want to find the equation that could represent the blue line
⇒ let's look into each equation and see whether they work or not
First case: [tex]y = -x[/tex]
⇒The equation given has the line falling, when the graph in the
equation is rising
⇒ not the answer
Second case: [tex]y=2x[/tex]
⇒ the equation given has the line that has a bigger slope than the
the equation shown, which has a smaller slope than y = x
⇒ not the answer
Third case: [tex]y=\frac{1}{2}x[/tex]
⇒ the equation given fits the requirement of having a rising slope that
is smaller than y = x
⇒ is a possible answer
Fourth case: [tex]y = 0.001x[/tex]
⇒ the equation given has a slope that is almost horizontal when the
line shown in the graph doesn't
⇒ not the answer
Thus after examing all the choices:
⇒ Answer: [tex]y=\frac{1}{2}x[/tex]

Verify the property p × q = q × p of the rational numbers using p =5/28 and q=49/35
The commutative property of multiplication is verified for the case when p =5/28 and q=49/35 because we get p × q = 0.25 = q × p
What is the difference between verification and proof?Proof usually is generalized, ie, it applies for all possible cases of the given condition, or a large set of cases. But vertification is a check for single special case.
For this case, we've to verify that p × q = q × p when p =5/28 and q=49/35
For p =5/28 and q=49/35 we get:
[tex]p \times q = \dfrac{5}{28} \times \dfrac{49}{35} = \dfrac{5 \times 49}{28 \times 35}\\\\\\p \times q = \dfrac{245}{980} = 0.25[/tex]
Also, we get:
[tex]p \times q =\dfrac{49}{35} \times \dfrac{5}{28} = \dfrac{49 \times 5}{35 \times 28}\\\\\\p \times q = \dfrac{245}{980} = 0.25[/tex]
Thus, we get: p × q = 0.25 = q × p
Hence, verified.
Thus, the commutative property of multiplication is verified for the case when p =5/28 and q=49/35 because we get p × q = 0.25 = q × p

Netflix is considering a new romcom (romantic comedy) series. Before making a final decision, the producers design an experiment to estimate the proportion of viewers who would watch the series. A random sample of 1,040 viewers was selected and asked to watch the first two episodes. After viewing the episodes, 650 viewers indicated they would watch the new series. (Use t Distribution Table & z Distribution Table. ) (Round your answers to 3 decimal places. )
Required:
a. Estimate the value of the population proportion of people who would watch the new series.
b. Develop a 99% confidence interval for the population proportion of people who would watch the new series.
Using the z-distribution, as we are working with a proportion, it is found that:
a) The population proportion is of 0.625.
b) The interval is (0.586, 0.664).
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.In this problem, we have a 99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.
The sample size and the population proportion are given, respectively, by:
[tex]n = 1040, \pi = \frac{650}{1040} = 0.625[/tex]
Hence, the bounds of the interval are given by:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.625 - 2.575\sqrt{\frac{0.625(0.375)}{1040}} = 0.586[/tex]
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.625 + 2.575\sqrt{\frac{0.625(0.375)}{1040}} = 0.664[/tex]

A sheet of plywood costs $10. 75. Production is down which causes the price to rise 25%. What is the new price?
Answer:
The answer should be somewhere around 13.4375
Step-by-step explanation:
Since the price is 10.75 and it wants you to add 25% or a quarter to it. You can divide 10.75 by 4, which is 2.6875 and add it. You will get 13.4375.

how do you round 81.59 to the nearest whole number?
Answer:
The number (81.59) will round to 82.
Step-by-step explanation:
First, let us understand what the question means by "whole numbers".
What are whole numbers?Whole numbers are such integers that are positive. (Except 0, which is a non-positive and non-negative integer).
Whole numbers: 0, 1, 2, 3, 4, 5, 6....
If the number before the decimal is smaller than 50, then the number will round down. If the number before the decimal is greater than or equal to 50, then the number will round up.
We can see that 81.59 is between two integers (81 and 82). Therefore, 81.59 can either round down to 81 or round up to 82.
Since the number after the decimal (81.59) is greater than 50, the number rounds up to 82. Therefore, the number (81.59) will round to 82.

Step-by-step explanation:
The arc length is just a fraction of the circumference of the circle which we know is represented by the equation L=2πr.
The radius is given ad 6. So the circumference is:
2*π*6=12π
Now, since the angle of the arc is 90°, this is 1/4 of the circle.
This means that the arc length of this section will be 1/4th of the total circumference which is:
12π/4=3π
At a restaurant, 42 people had breakfast on Saturday morning.
1/7• of the people ate eggs only.
2/3 • of the people ate both pancakes and eggs.
• The remaining people ate pancakes only.
Which fraction represents the number of people who ate pancakes only?
Answer:
17/21
Step-by-step explanation:
The amount of people that ate eggs only are:
42* 1/7 = 6
The amount of people that ate both pancakes and eggs are:
42 * 2/3 = 28
That means 34 people ate pancakes only.
The fraction that represents this is 34/42 = 17/21

Using the binomial distribution, it is found that there is a 0.25 = 25% probability of getting exactly 3 tails.
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:
A fair coin is equally as likely to result in heards or in tails, hence p = 0.5.The coin is tossed 4 times, hence n = 4.The probability of getting 3 tails is P(X = 3), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{4,3}.(0.5)^{3}.(0.5)^{1} = 0.25[/tex]
0.25 = 25% probability of getting exactly 3 tails.

the third angle?
A 30°

C, 60 degrees
Step-by-step explanation:
Right Triangle, with a 30 degree angle:
Given degrees:
90 (Right Triangle)
30
90+30 = 120
180-120 = 60
180 Degrees total in a triangle, you simply subtract the measure you have to fidn the third one.
Answer:
The measure of the third angle is 60°.
Step-by-step explanation:
We are given a right triangle that has a 90 degree and two other angles that are unknown.
Since one known angle is 90° and another angle given is 30° then the third angle must be 60°. All triangles must add up to 180°.
180° - 90° - 30° = 60°.

C) The greatest common factor of 13 and 21 is 3.
Write down the factors of 13 and 21.
⇒ Factors of 13: 1 and 13
⇒ Factors of 21: 1, 3, 7, 21
We can see here that the GCF is "1" as it is the greatest factor of 13 and 21.
Hence, option C is incorrect.
D) The greatest common factor of 14 and 21 is 3.
Write down the factors of 14 and 21.
