Answer:
About 95% of households have an income over $54,550
Step-by-step explanation:
95% is a probability of around 0.95
So we start by calculating the z-score with a probability of 0.95
We can use the standard normal distribution table for this
the z-score is -1.645
Mathematically;
z-score = (x-mean)/SD
-1.645 = (x-71,000)/10,000
10,000 * -1.645 = x-71,000
-16450 = x - 71000
x = 71,000 - 16450
x = 54,550

For parties of six or more, a restaurant adds a 20% gratuity (or tip). Ifa
dinner bill for a large party comes to $148.25, find the total dinner bill with
tip.
Answer:
$247.37
Step-by-step explanation:
The total dinner bill with a tip for the large party is $177.90.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
For example 4×2 = 8
The gratuity for a large party is 20% of the bill, so we can calculate the gratuity by multiplying the bill by 0.2.
Gratuity = bill x 0.2
Gratuity = 148.25 x 0.2
Apply the multiplication operation, and we get
Gratuity = 29.65
To find the total bill, we add the gratuity to the original bill.
Total bill = bill + gratuity
Total bill = 148.25 + 29.65
Apply the addition operation, and we get
Total bill = $177.90
Hence, the total dinner bill with a tip for the large party is $177.90.

Sandi buys 5 fewer packages of pencils than p packages of pens. Pencils costs $2.25 per package and pens costs $3 per package. What does the expression 3p + 2.25(p - 5) represent?
Answer:
3p + 2.25(p - 5) represents the total cost of the pens and pencils that Sandi bought.
Step-by-step explanation:
p = number of packages of pens
p - 5 = number of packages of pencils
3p = cost of p packages of pens
2.25(p - 5) = cost of p - 5 packages of pencils
3p + 2.25(p - 5) represents the total cost of the pens and pencils that Sandi bought.
We are to determine what the expression 3p + 2.25(p - 5) represent.
let
packages of pens = p
packages of pencils = p - 5
cost of p - 5 packages of pencil = $2.25
cost of p packages of pen = $3
Total cost of pencil and pen = (p)3 + (p - 5)2.25
= 3p + 2.25(p - 5)
The expression 3p + 2.25(p - 5) represent total cost of pen and pencils sandi bought

Susan has a collection of 48 nickles and dimes. If the number of nickles is three times the number of dimes, how many nickles and how many dimes dose she have?
Answer:
12 dimes and 36 nickels
Step-by-step explanation:
Let number of dimes be x. Since the number of nickles is three times the number of dimes, the number of nickels is 3x. There are a total of 48 coins, so number of nickels + number of dimes = 3x + x = 4x = 48 -> x =12. So she has 12 dimes and 3(12) = 36 nickels.

A data set can have more than one median? True False
Answer:
False
Step-by-step explanation:
The given statement "A data set can have more than one median" is False.
What are mean and median?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
Median; It represents the middle value of the given data when arranged in a particular order.
Mode; It is that number that appears most frequently in the given set of data.
Given the statement as; A data set can have more than one median.
If the value changed is not the middle value (if number of observations are odd) or is not changing the average of two mid values (if number of observations are even), then the median won't change as it does not care about the value of the data unless its about the mid value of the sorted data or average of mid values.
Since the median and mean can only have one value for a given data set. The mode can have more than one value
The given statement is False.
