25-(√16-1)·(3-9)² what is the answer?
Answers
Answer:
-155
Step-by-step explanation:
25-(√16-1)·(3-9)²
25 - (1 * 6 - 1)(3 - 9)^2
(1 * 6 -1)(3 - 9)^2 = 6^2 * 5
25 - 6^2 * 5
5 * 6^2 = 180
25 - 180
= -155
The answer to the given expression 25-(√16-1)·(3-9)² will be -83.
What is an expression?A mixture of variables,n umbers, addition, subtraction, multiplication, and division are called expressions.
A mathematical expression serves as proof that two mathematical expressions are equal.
A statement expressing the equality of two mathematical expressions is known as an equation.
Given,
25-(√16-1)·(3-9)²
Since √16 = 4
⇒ 25-(4-1)·(3-9)²
⇒ 25 - 3(-6)²
⇒ 25 - 3 ×36
⇒ -83
Hence, the answer to the given expression 25-(√16-1)·(3-9)² will be -83.

A person makes an overseas phone call. The telephone company charges 65 cents for the first minute and then 75 cents for each minute thereafter. Because it's an overseas phone call, there is also a 55 cent service charge. If the phone call cost $ 19.20 , how many minutes did this person talk?
Answers
Answer:
25 minutes.
Step-by-step explanation:
A person makes an overseas call.
The telephone company charges 65 cents for the first minute.
Then 75 cents for each minute thereafter.
There is a 55 cent service charge.
1 dollar = 100 cents
65 cents = $0.65
75 cents = $0.75
55 cents = $0.55
For a phone call that cost $19.20 ;
Subtracting the service charge and the first minute charge from overall cost we get;
$19.20 - $0.55 - $0.65 = $18
For every additional minute there is a charge of $0.75
How many minutes make $18 ;
Cross multiplying this gives;
[tex]\frac{18}{0.75} * 1[/tex] = 24 minutes.
So the call lasted 24 minutes + 1 minute = 25 minutes.

"When comparing the means of two independent samples, the population standard deviations will almost always be"
Answers
Answer: Check this answer!
Step-by-step explanation:
The comparison of two independent population means is very common and provides a way to test the hypothesis that the two groups differ from each other. Is the night shift less productive than the day shift, are the rates of return from fixed asset investments different from those from common stock investments, and so on? An observed difference between two sample means depends on both the means and the sample standard deviations. Very different means can occur by chance if there is great variation among the individual samples. The test statistic will have to account for this fact. The test comparing two independent population means with unknown and possibly unequal population standard deviations is called the Aspin-Welch t-test.
In simple terms, The population standard deviation is a parameter, which is a fixed value calculated from every individual in the population. A sample standard deviation is a statistic. This means that it is calculated from only some of the individuals in a population. Since the sample standard deviation depends upon the sample, it has greater variability. Thus the standard deviation of the sample is greater than that of the population
Because: reason:
Since the sample standard deviation depends upon the sample, it has greater variability. Thus the standard deviation of the sample is greater than that of the population.

List the smallest three values in the set below. {x | x ∈ N and 20 < x}
Answers
Answer:
21, 22 and 23Step-by-step explanation:
Given the set A = {x | x ∈ N and 20 < x} , from the set it can be seen that the element of the set are natural numbers where 20< x.
If 20< x
reciprocating both sides will change the sense of the inequality
1/20>1/x
cross multiply
x > 20
This means that the values of x are values grater than 20.
The smallest three values will be the smallest three natural numbers greater than 20 and they are 21, 22 and 23. Note that natural numbers are whole numbers.

A random sample of 16 students selected from the student body of a large university had an average age of 25 years and a standard deviation of 2 years. We want to determine if the average age of all the students at the university is significantly more than 24. Assume the distribution of the population of ages is normal. The p-value is between
Answers
Answer:
The P-value is between 2.5% and 5% from the t-table.
Step-by-step explanation:
We are given that a random sample of 16 students selected from the student body of a large university had an average age of 25 years and a standard deviation of 2 years.
Let [tex]\mu[/tex] = true average age of all the students at the university.
So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu \leq[/tex] 24 years {means that the average age of all the students at the university is less than or equal to 24}
Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] > 24 years {means that the average age of all the students at the university is significantly more than 24}
The test statistics that will be used here is One-sample t-test statistics because we don't know about the population standard deviation;
T.S. = [tex]\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }[/tex] ~ [tex]t_n_-_1[/tex]
where, [tex]\bar X[/tex] = sample average age = 25 years
s = sample standard deviation = 2 years
n = sample of students = 16
So, the test statistics = [tex]\frac{25-24}{\frac{2}{\sqrt{16} } }[/tex] ~ [tex]t_1_5[/tex]
= 2
The value of t-test statistics is 2.
Also, the P-value of test-statistics is given by;
P-value = P( [tex]t_1_5[/tex] > 2) = 0.034 {from the t-table}
The P-value is between 2.5% and 5% from the t-table.

It takes Three hours for a highway worker to mow the grass on a stretch of highway. It takes 6 hours for a different highway worker to mow the grass on the same stretch of highway. How many hours will it take for the two highway workers to mow the grass together on this stretch of highway?
Answers
Answer:
Step-by-step explanation:
4.5
The required time that two highway workers to mow the grass together on this stretch of highway is 2 hours,
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Rate of doing for highway workers A = 1 / 3
Rate of doing for highway workers B = 1 / 6
Now total rate,
= 1 / 3 + 1 / 6
= 2 + 1 / 6
= 3 / 6
= 1 / 2
Now,
it takes for the two highway workers to mow the grass together on this stretch of highway,
Time = 1 / 1 / 2
Time = 1 * 2 / 1
Time = 2 hours,
Thus, the required time that two highway workers to mow the grass together on this stretch of highway is 2 hours,

Answer:
x minus y: when it says "minus", it means substracting, so x - y.
The product of two numbers: If we call one x and the other y, the product of them is the same as multiplying them, so xy.
The product of two numbers is six: If we call one x and the other y, the product of them is the same as multiplying them and we know the result of doing so is 6, so xy = 6
Six less than a number is y: So if we substract x to a number, the result is y, so 6 - x = y
x substracted by y: this means we substract x from y, which is the same than y minus x, so y - x
y divided by x: this means y is being divided by x, so y/x
The sum of two numbers is six: That means we sum x and y, and the result is 6, so x + y = 6
x divided by y: This means x is being divided by y, so x/y
The sum of x and y: this means both numbers are summing, so x + y
Six times a number equals y: This means 6 per a number (let it be x) is equal to y, so 6x = y
