What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
A garden store purchased a lawn mower and marked it up 160% from the original cost of $82.67.
So, the Marked up amount
= 160 % of 82.67
= $132. 272
and, then 10% discount
= 10% of 132.272
= 13.2272
so, the discount price = 82.67 - 13.2272 = $69.4428

A quality control expert at a drink bottling factory took a random sample of bottles from a batch and measured
the amount of liquid in each bottle in the sample. The amounts in the sample had a mean of 503 mL and a
standard deviation of 5 mL. They want to test if this is convincing evidence that the mean amount for bottles in
this batch is different than the target value of 500 mL.
Let u be the mean amount of liquid in each bottle in the batch.
Which of the following is an appropriate set of hypotheses for their significance test?
Answer: A
Step-by-step explanation:
The correct hypothesis is Option A.
What are hypotheses in mathematics?A hypothesis is a supposition or suggested explanation for a phenomenon or issue. It is a preliminary claim that has to be examined and confirmed by logic, experimentation, or other means. A hypothesis can be used to steer the development of a theory or to make predictions about events that will happen in the future.
The appropriate set of hypotheses for this significance test is:
μ = 500 mL (null hypothesis) - The mean amount of liquid in each bottle in the batch is equal to the target value of 500 mL.
μ ≠ 500 mL (alternative hypothesis) - The mean amount of liquid in each bottle in the batch differs from the target value of 500 mL.
This is done in order to determine whether there is proof that the average volume of the bottles in this batch differs from the desired value of 500 mL.
The alternative hypothesis suggests that the mean quantity is different from the null hypothesis assumption that it is equal to 500 mL. The test will evaluate whether there is enough support for the alternative hypothesis to be accepted instead of the null hypothesis.

The weight of oranges growing in an orchard is normally distributed with a mean weight of 7 oz. and a standard deviation of 1.5 oz. Using the empirical rule, determine what interval would represent weights of the middle 99.7% of all oranges from this orchard.
please help
Answer:
2 to 11 ounces would be the interval.
Step-by-step explanation:
Add 3 standard deviations above and below the mean to get the range in which 99.7% of the data in a normal distribution will fall
6.5 + 4.5 = 11
6.5 - 4.5 = 2.
Hope this helped!
The interval that would represent the weights of the middle [tex]99.7\%[/tex] of all oranges from this orchard is between [tex]2.5[/tex] and [tex]11.5[/tex] such that weight and standard deviation are [tex]7\;\text{oz.}[/tex] and [tex]1.5\;\text{oz.}[/tex] respectively.
Empirical RuleThe empirical rule formula states that [tex]68\%,95\%[/tex] and [tex]99.7\%[/tex] of all the data can be represented in the interval of [tex]1, 2[/tex] and [tex]3[/tex] standard deviation of the mean respectively.
How to use the empirical rule formula to determine the interval?Mean weight [tex]=7\;\text{oz.}[/tex]
Standard deviation [tex]=5\;\text{oz.}[/tex]
According to the empirical rule, [tex]99.7\%[/tex] of values lie within [tex]3[/tex] standard deviations of the mean.
So, we have to add and subtract [tex]1.5[/tex] three times in mean weight to obtain the required interval.
[tex]\Rightarrow7-4.5 < 7 < 7+4.5\\\Rightarrow2.5 < 7 < 11.5[/tex]
Thus, the interval that would represent the weights of the middle [tex]99.7\%[/tex] of all oranges from this orchard is between [tex]2.5[/tex] and [tex]11.5[/tex].

Is there a pattern behind prime numbers?
Answer:
There is a rule on how we find prime numbers.
Step-by-step explanation:
A clear rule determines exactly what makes a prime: it's a whole number that can't be exactly divided by anything except 1 and itself. But there's no discernible pattern in the occurrence of the primes.That's because, after the number 5, there are only four possibilities — 1, 3, 7, and 9 — for prime last digits

a bank loaned out $19000, part of it at the rate of 7% per year and the rest at 15% per year. if the interest received in one year totaled $2000, how much was loaned at 7%? How much of the $19000 did the bank loan out at 7%?
Answer:
10625
Step-by-step explanation:
Let x= the amount loaned at 7%
which means that the amount loaned at 15% is 19000-x (or the rest of the money)
we can write the following equation
x*.07+(19000-x)(.15)=2000
solve for x
.07x+2850-.15x=2000
-.08x= -850
x=10625
