It is common to leave a 10% tip when the service was just mediocre. At one such occasion, a patron left a 10% tip on a $23.45 bill.
What is the tip amount?
What is the total bill?
Answer: $2.3
Step-by-step explanation: well you need to find 10% of 23.45, so multiply .1 by 23.45.
[tex]23.45 \times 10\%[/tex]
[tex] = 23.45 \times 0.1[/tex]
[tex] = 2.345[/tex]
[tex] = 2.35[/tex]Answer:$2.35 is the tip amount
What is the total bill?Solution:[tex]23.45 + 2.345[/tex]
[tex] = 25.795[/tex]
[tex] = 25.80[/tex]
Answer:$25.80 is the total bill

Step-by-step explanation:
Describe all the x-values at a distance of 25 or less from the number 12. Enter your answer in interval notation.
Answer: [-13, 37]
======================================================
Explanation:
The smallest x value possible is 12-25 = -13
The largest x value possible is 12+25 = 37
It might help to draw out a number line to see this.
x is between -13 and 37, including both endpoints. We can write [tex]-13 \le x \le 37[/tex]
This converts to the interval notation [-13, 37] which is the answer.
The use of square brackets is to indicate "include this endpoint".

the product of two number is 42.they are two consecutive numbers. the two numbers are both less than 10. what is the answer?
Answer:
6 and 7
Step-by-step explanation:
You first want to find the factors of 42. They are:
1,2,3,6,7,14,21,42
The factor pairs are:
1 & 422&213&146&7The only factor pair with consecutive numbers is 6 and 7. They are both less than 10 as well, so 6 and 7 works.

Twenty-percent (20%) of Americans have no health insurance. Randomly sample n = 15 Americans. Let X denote the number in the sample with no health insurance. What is the probability that 3 of them have insurance?
Answer:
0% probability that 3 of them have insurance
Step-by-step explanation:
For each American, there are only two possible outcomes. Either they have insurance, or they do not. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Twenty-percent (20%) of Americans have no health insurance.
This means that 80% have insurance, so [tex]p = 0.8[/tex]
Randomly sample n = 15 Americans.
This means that [tex]n = 15[/tex]
What is the probability that 3 of them have insurance?
This is [tex]P(X = 3)[/tex]
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{15,3}.(0.8)^{3}.(0.2)^{12} = 0[/tex]
0% probability that 3 of them have insurance

You owe $300 on your credit card. For every month that you fail to make a payment, your balance increases by 1%. Find a formula for the balance B owed after t months with no payment.
Answer:
[tex]B(t) = 300(1.01)^{t}[/tex]
Step-by-step explanation:
The balance owed after t months can be given by an exponential function in the following format:
[tex]B(t) = B(0)(1+r)^{t}[/tex]
In which B(0) is the initial balance owed and r is the growth rate, as a decimal.
You owe $300 on your credit card. For every month that you fail to make a payment, your balance increases by 1%.
This means, respectively, that [tex]B(0) = 300, r = 0.01[/tex]
So
[tex]B(t) = 300(1+0.01)^{t}[/tex]
[tex]B(t) = 300(1.01)^{t}[/tex]
Perry has already taken 8 pages of notes on his own, and he will take 1 page during each
hour of class. After attending 33 hours of class, how many total pages of notes will Perry
have in his notebook?
Answer:
41 pages of notes
Step-by-step explanation:
Since he took 1 page of notes for each hour, and attended 33 hours of class, this will add 33 pages of notes to his notebook.
To find the total, add 8 to this, because he already had 8 pages on his own.
33 + 8
= 41
So, he will have 41 pages of notes in his notebook
Answer:
He will have 41 pages of notes in his notebook.
Step-by-step explanation:
(33*1)+8
30*1=30
3*1=3
30+3=33

The change is a decrease by ~13.6%
Step-by-step explanation:
Formula:
[First Value – Second Value] ÷ [(First Value + Second Value) ÷ 2] × 100
48 - 84 ÷ 48 + 84 ÷ 2 × 100
-36 ÷ 132 ÷ 2 × 100
-0.2727272727272727 ÷ 2 × 100
-0.1363636363636364 × 100
-13.63636363636364

Step-by-step explanation:
The length of a rectangle is 3 yd longer than its width.
If the perimeter of the rectangle is 66 yd, find its length and width.
length = 3 + w (width)
perimeter: 66
2(3 + w + w) = 66
6 + 2w + 2w = 66
6 + 4w = 66
4w = 60
w = 15
length = 15 + 3 = 18
final answer:
length = 15 yards
width = 18 yards

Step-by-step explanation:
20. Jorge conducted a survey by asking 120 students whether they use a pencil to take notes. Of the students surveyed, 90 responded favorably. Which margin of error matches each confidence level for this situation?
1. 90% =
2. 99% =
3. 95%=
options- 0.102, 0.338, 0.216, 0.077, 0.256, 0.065
Answer:
Margin of error for 90% C.I: 0.065
Margin of error for 99% C.I: 0.091
Margin of error for 95% C.I: 0.077
Step-by-step explanation:
In this question, for each student, there are only two possible outcomes. Either they use a pencil to take notes, or they do not. Students are independent of each other. So we use the binomial probability distribution to solve this question.
Binomial confidence interval:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
For this problem, we have that:
120 students, so [tex]n = 120[/tex]
90 responded favorably, so [tex]p = \frac{90}{120} = 0.75[/tex]
Margin of error for 90% CI:
Here [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}} = 1.645\sqrt{\frac{0.75*0.25}{120} = 0.065[/tex]
Margin of error for 99% CI:
Here [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.325[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}} = 2.325\sqrt{\frac{0.75*0.25}{120} = 0.091[/tex]
Margin of error for 95% CI:
Here [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}} = 1.96\sqrt{\frac{0.75*0.25}{120} = 0.077[/tex]
Answer: Margin of error for 99% CI: z=2.575 . input that into the equation and it give you .1017
