The Royal Fruit Company produces two types of fruit drinks. The first type is 65% pure fruit juice, and the second type is 100% pure fruit juice. The company is attempting to produce a fruit drink that contains 70% pure fruit juice. How many pints of each of the two existing types of drink must be used to make 140 pints of a mixture that is 70% pure fruit juice?
The fruit drink which contains 70 % fruit juice will have 120 pints of 65 % pure fruit juice and 20 pints of 100% pure fruit juice.
Given that:-
Two types of juice are 65 % fruit juice and 100 % pure fruit juice.
The company is attempting to produce a fruit drink that contains 70% pure fruit juice.
We have to find the amount of each of 65% pure fruit juice and 100 % pure fruit juice which contains 70 % fruit juice with 140 pints of total juice.
Let the amount of 65 % pure fruit juice be x pints and,
The amount of 100 % pure fruit juice be y pints
We know that,
x + y = 140 ...(1)
Also,
Using weighted mean, we can write,
(65x + 100y)/(x + y) = 70
65x + 100y = 70x + 70y
5x = 30y
x = 6y
Putting x = 6y in (1), we get
6y + y = 140
7y = 140
y =140/7
y = 20 pints
x = 6y = 6*20 = 120 pints

The mean of the sampling distribution of proportion is 0.15
The probability the sample proportion will be within 0.04 of the population proportion is 0.9182
The probability the sample proportion that will be within 0.02 of the population proportion is 0.6157
P(Smokers) in Australia= 15/100=0.15
Sample, n =240
Part a, The mean of the sampling distribution of proportion:
μ₂ = P(Smokers)
= 0.15
The mean of the sampling distribution of proportion is 0.15
The standard deviation of the sampling distribution of proportion is,
δ [tex]=\sqrt{p\frac{(1-p)}{n} }[/tex]
[tex]=\sqrt{0.15\frac{(1-0.15)}{240} }[/tex]
[tex]=0.0230[/tex]
The standard deviation of the sampling distribution of proportion is 0.0230
Part b, The probability the sample proportion will be within +/-0.04 of the population proportion:
To find this, we first, compute the z score then find probability based on standard normal table.
For 0.15-0.04, p=0.11 and converts to:
[tex]z=\frac{p-u_{p} }{standard deviation} \\[/tex]
[tex]=\frac{0.11-0.15}{0.0230}[/tex]
= -1.74
For 0.15+0.04, p=0.19, and converts to:
[tex]z=\frac{0.19-0.15}{0.0230}[/tex]
= 1.74
From the standard normal distribution table, the associated probability for z values and subtracts the probability is,
[tex]=p(-1.74\leq z\leq 1.74)[/tex]
[tex]=0.9591-0.0409[/tex]
[tex]=0.9182[/tex]
Hence, the probability the sample proportion will be within 0.04 of the population proportion is 0.9182
Part c, the probability the sample proportion will be within 0.02 of the population proportion:
First, compute the z score then find probability based on standard normal table.
For 0.15-0.02, p=0.13, and converts to:
[tex]=\frac{0.13-0.15}{0.0230}[/tex]
=-0.87
For 0.15+0.02, p=0.17, this converts to:
[tex]=\frac{0.17-0.15}{0.0230}[/tex]
=0.87
From the standard normal distribution table, the associated probability for z values and subtracts the probability is,
[tex]=p(-0.87\leq z\leq 0.87)[/tex]
[tex]=0.8079-0.1922[/tex]

3 In an election, a good candidate may lose because 40% of voters do not cast their votes due
to various reasons. Form an equation and draw the graph with data. From the graph, find:
(i) The total number of voters, if 720 voters cast their votes.
The total number of voters is 1200, and out of that 720 voters cast their votes.
Let's take total voters = V
The percentage of voters do not cast their votes due to various reasons is 40%.
Therefore, Voters did not cast their votes = (40÷100)V = 0.4V
As 0.4V voters did not cast their votes. To calculate the total number of voters who cast votes, divide (total) by (non-casted-voters):
Voters casted their votes = V - 0.4V = 0.6V
0.6V = 720
=> V = 1200
The total number of voters is 1200 if 720 voters cast their votes.

The height of a ball in feet can be found by the function h(t)=-16t^2+80t+5 where t is the elapsed time in seconds. Find the time or times that the ball is 34 feet high to the nearest tenth of a second
The times that the ball is 34 feet high to the nearest tenth of a second is equal to 4.61 and 0.39 seconds.
How to calculate the times?In order to determine the time or times for this ball at a height of 34 feet, we would simply substitute the value of the height into the function h(t) as follows;
h(t) = -16t² + 80t + 5
34 = -16t² + 80t + 5
Re-arranging the equation, we have:
16t² - 80t + 34 - 5 = 0
16t² - 80t + 29 = 0
Next, we would solve the quadratic equation by using the quadratic formula:
[tex]x = \frac{-b\; \pm \;\sqrt{b^2 - 4ac}}{2a}\\\\x = \frac{-(-80)\; \pm \;\sqrt{-80^2 - 4(16)(29)}}{2(16)}\\\\x = \frac{80\; \pm \;\sqrt{6400 - 1856}}{32}\\\\x = \frac{80\; \pm \;\sqrt{4544}}{32}[/tex]
x = (80 ± 8√71)/32

A % is a number that has neither established units of measurement nor dimensions.
The percentage can be calculated by taking the value and dividing it by the total value, then multiplying the result by 100. using the formula (Value/Total Value) × 100% to calculate percentages.
Let the total number of students be x.
Now 91% of this students is equal to 819.
Now using the properties of percentages we can write:
91% of x = 819
or, x = 900
Number of students who did not take French = 900 - 819 = 81
Hence using percentages we can say that 9% or 81 students did not take French.

which small digit represent M so that the number 2m234 and is divisible by 3
Answer:
m = 1
Step-by-step explanation:
A number is divisible by 3 if the sum of the digits is a multiple of 3
the given number is 2m234 and we are asked to find the smallest m
Adding up known digits gives 2 + 2 + 3 + 4 = 11
The next multiple of 3 is 12
So 11 + m = 12
m = 1
The other possibilities are
m = 4, m = 7
Lily is behind on her homework. The ritualistic teacher assigned exactly 5 homework assignments every day for the past 9 learning days. Here is the amount of homework assignments Lily has been able to get done each night (if she didn’t finish some of the 5 assignments from the night before, she would start work on them the next day): 3, 6, 2, 4, 3, 7, 1, 3, 2. If Lily doesn’t finish all her assignments, she won’t be able to go on a fun field trip next month. Lily can’t do more than 10 assignments in one night. There is one more homework night, with 5 more assignments. Can Lily still make it to the field trip?
Answer:
she cannot go on the field trip.
Step-by-step explanation:
Day 1 = 5, done = 3, remaining = 2.
Day 2 = 2 + 5, done = 6, remaining = 1
Day 3 = 1 + 5, done = 2, remaining = 4
Day 4 = 4 + 5, done = 4, remaining = 5
Day 5 = 5 + 5, done = 3, remaining = 2 + 5
Day 6 = 2 + 5 + 5, done = 7, remaining = 5
Day 7 = 5 + 5, done = 1, remaining = 4 + 5
Day 8 = 4 + 5 + 5, done = 3, remaining = 1 + 5 + 5
Day 9 = 1+ 5+ 5+ 5, done = 2, remaining = 4+5+5
Day 10 = 4+5+5+5, done = 10(maximum assignment done assumed), remaining = 4 + 5
At the end of day 10, she had 9 remaining assignments, so she cannot go on the field trip.

workers are helping shingle the
roof.
Each relationship should be matched with the correct description as follows:
Direct variation: the amount of time it takes to drive some place depends on the distance.Joint variation: the volume of a can depends on its radius and on its height.Indirect variation: the time it takes to shingle a roof depends on how many workers are helping shingle the roof.What is direct variation?Direct variation can be defined as a type of proportional relationship in which a variable is directly proportional to another variable.
What is an indirect variation?An indirect variation can be defined as a type of proportional relationship in which a variable is inversely proportional to another variable. This ultimately implies that, an indirect variation represents two variables that are inversely proportional to each other.
In conclusion, a joint variation describes a situation in which a variable depends on two other variables which share a directly proportional relationship.
