I WILL GIVE BRAINLESIT PLEASE I NEED HELP!!! 5a. When paying for a restaurant order, a customer spent $20.00 for a $17.00 meal. What percent was the tip? Round to the nearest tenth. 5b. When paying for a restaurant order, a customer's total for food was $30.00. What is a 18% tip for that total?
Answer:
5a. Tip was 17.65%
5b. Total was $35.4
Step-by-step explanation:
5a.
Create the following equation:
17 + 17x = 20
17x = 3
x = 3/17
5b.
Find 18% of 30.
30 x 0.18 = 5.4
Add 5.4 to 30.
30 + 5.4 = 35.4

268 = n = 0.268
n=
What is the value of n
Answer:
Simplifying
268 + n = 0.268
Solving
268 + n = 0.268
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-268' to each side of the equation.
268 + -268 + n = 0.268 + -268
Combine like terms: 268 + -268 = 0
0 + n = 0.268 + -268
n = 0.268 + -268
Combine like terms: 0.268 + -268 = -267.732
n = -267.732
Simplifying
n = -267.732

$297.41
$193.13
$560.59
$211.12
Answer:
$297.41
Step-by-step explanation:
Given that:
Amount = 9270
Derferred period = 6 months = 0.5 yr
Rate = 17.95% = 0.1795
Amount = 9270(1 + 0.1795)^0.5
Amount = 9270(1.1795)^0.5
Amount = 10067.663
PV = 10067.663
Number of months, n = 48
Monthly amount to be paid :
rp = rate per period = 0.1795/12 = 0.0149583
(rp * PV) / 1 - (1 + rp)^-n
(0.0149583 * 10067.663) / 1 - (1 + 0.0149583)^-48
150.5951234529 / 0.5096723
= 295.47441

Use the following information for the question. Male players at the high school, college and professional ranks use a regulation basketball that weighs 22.0 ounces with a standard deviation of 1.0 ounce. Assume that the weights of basketballs are approximately normally distributed. Roughly what percentage of regulation basketballs weigh more than 23.1 ounces
Answer:
13.567%
Step-by-step explanation:
We solve the above question, using z score formula
z = (x-μ)/σ, where
x is the raw score = 23.1 ounces
μ is the population mean = 22.0 ounces
σ is the population standard deviation = 1.0 ounce
More than = Greater than with the sign = >
Hence, for x > 23.1 ounces
z = 23.1 - 22.0/1.0
= 1.1
Probability value from Z-Table:
P(x<23.1) = 0.86433
P(x>23.1) = 1 - P(x<23.1)
P(x>23.1) = 1 - 0.86433
P(x>23.1) = 0.13567
Converting to percentage
= 0.13567 × 100
= 13.567%
Therefore, the percentage of regulation basketballs that weigh more than 23.1 ounces is 13.567%

Step-by-step explanation:
On their most recent 8-mile training run, Pepe averaged a speed of
I of a mile in 4.5 minutes, while Paula averaged of a mile in 7.5
minutes.
How many minutes did it take the faster runner to finish the 8 mile
run?
Answer:
36 minutes
Step-by-step explanation:
Given that:
The length of run = 8 miles
Average speed of Pepe = 4.5 minutes per minute
Average speed of Paula = 7.5 minutes per minute
To find:
Minutes taken by the faster runner to finish the 8 mile run?
Solution:
First of all, let us have a look at the relation between Time and Speed.
[tex]Speed = \dfrac{Distance}{Time}[/tex]
If the distance is a constant, then
[tex]Speed \propto \dfrac{1}{Time}[/tex]
i.e. Speed is inversely proportional to time.
That means faster runner will take smaller amount of time.
So, faster runner is Pepe who is taking lesser time.
Time taken to complete 1 mile = 4.5 minutes
Time taken to complete 8 miles = 4.5 [tex]\times[/tex] 8 minutes = 36 minutes
So, the faster runner i.e. Pepe takes 36 minutes.
Which function is the inverse of f(x) = -5x -4?
Answer:
f^-1(x) = (x + 4) / -5
Step-by-step explanation:
f(x) = -5x - 4 Substitute f(x) with y
y = -5x - 4 Switch the x and y variables
x = -5y - 4 Solve it down
x + 4 = -5y
y = (x + 4)/ -5
f^-1(x) = (x + 4) / -5 <----- This is the answer

Step-by-step explanation:
A researcher reports survey results by stating that the standard error of the mean is 25 the population standard deviation is 400. Use z-table.
a. How large was the sample used in this survey?
b. What is the probability that the point estimate was within ±15 of the population mean?
Answer:
a) A sample of 256 was used in this survey.
b) 45.14% probability that the point estimate was within ±15 of the population mean
Step-by-step explanation:
This question is solved using the normal probability distribution and the central limit theorem.
Normal probability distribution
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
a. How large was the sample used in this survey?
We have that [tex]s = 25, \sigma = 400[/tex]. We want to find n, so:
[tex]s = \frac{\sigma}{\sqrt{n}}[/tex]
[tex]25 = \frac{400}{\sqrt{n}}[/tex]
[tex]25\sqrt{n} = 400[/tex]
[tex]\sqrt{n} = \frac{400}{25}[/tex]
[tex]\sqrt{n} = 16[/tex]
[tex](\sqrt{n})^2 = 16^2[tex]
[tex]n = 256[/tex]
A sample of 256 was used in this survey.
b. What is the probability that the point estimate was within ±15 of the population mean?
15 is the bounds with want, 25 is the standard error. So
Z = 15/25 = 0.6 has a pvalue of 0.7257
Z = -15/25 = -0.6 has a pvalue of 0.2743
0.7257 - 0.2743 = 0.4514
45.14% probability that the point estimate was within ±15 of the population mean
