Write out the five number summary for each data set.
I'll do problem 1 to get you started
First sort the values from smallest to largest and you should end up with this set
{1, 6, 7, 11, 13, 16, 18, 21, 22, 23}
The smallest value is 1 and the largest value is 23, so the min and max are 1 and 23 in that order.
We have ten values in this set. The middle-most number is going to be between the 10/2 = 5th slot and the 6th slot. The numbers 13 and 16 are in the fifth and sixth slots respectively. Average those values to get (13+16)/2 = 29/2 = 14.5
The median is 14.5 which is another name for the second quartile (Q2).
Now split the data set into two halves
L = lower half of values smaller than the median
U = upper half of values larger than the median
In this case,
L = {1, 6, 7, 11, 13}
U = {16, 18, 21, 22, 23}
sets L and U have five items each
Find the median of set L and U to get 7 and 21 respectively. These medians of L and U represent the values of Q1 and Q3 in that order.
Q1 = first quartile = 7
Q3 = third quartile = 21
===================================================
Answer:
The five number summary for problem 1 is
Minimum = 1Q1 = 7Q2 = 14.5 (this is the median)Q3 = 21Maximum = 23Can someone help, please

4. Write an equation of the line with slope 2/3 that goes through the point (-2,5).
Uring lunch hour at a local restaurant, 90% of the customers order a meat entrée and 10% order a vegetarian entrée. Of the customers who order a meat entrée, 80% order a drink. Of the customers who order a vegetarian entrée, 40% order a drink. What is the percent of customers who order a drink with their entrée?
Answer:
Total percent of customers who order a drink with their entrée = 76%
Step-by-step explanation:
Let
Total customers = 100%
customers who order a meat entrée = 90%
customers who order a vegetarian entrée = 10%
Of the customers who order a meat entrée, 80% order a drink
% of customers who order a meat entrée and drink = 80% of 90%
= (80/100 * 90/100) * 100
= (0.8 * 0.9) * 100
= 0.72 * 100
= 72%
% of customers who order a meat entrée and drink = 72%
Of the customers who order a vegetarian entrée, 40% order a drink.
% of customers who order a vegetarian entrée and drink = 40% of 10%
= (40/100 * 10/100) * 100
= (0.4 * 0.1) * 100
= 0.04 * 100
= 4%
% of customers who order a vegetarian entrée and drink = 4%
What is the percent of customers who order a drink with their entrée?
Total percent of customers who order a drink with their entrée = % of customers who order a meat entrée and drink + % of customers who order a vegetarian entrée and drink
= 72% + 4%
= 76%
Total percent of customers who order a drink with their entrée = 76%
If $9x^2 - 16x + k$ is a perfect square trinomial, find $k$.
The answer to the above statement is: $k$ has a perfect square trinomial value of 16.
To determine the value of $k$ such that $9x^2 - 16x + k$ is a perfect square trinomial, we can follow these steps:
Identify the form of a perfect square trinomial. A perfect square trinomial can be written in the form $(ax + b)^2$, where $a$ and $b$ are constants.
Examine the $9x2 - 16x + k$ trinomial in comparison to the perfect square trinomial form. We need to match the quadratic term and the linear term.
The quadratic term in the perfect square trinomial is $(ax)^2 = a^2x^2$, which corresponds to $9x^2$ in our trinomial.
The linear term in the perfect square trinomial is $2abx$, which corresponds to $-16x$ in our trinomial.
By comparing the terms, we can set up the following equation: $2abx = -16x$. This implies that $2ab = -16$.
Solve for $a$ and $b$ using the equation $2ab = -16$.
Let's consider possible factor pairs of $-16$: $(1, -16)$, $(2, -8)$, and $(4, -4)$.
We need to find a pair $(a, b)$ such that $2ab = -16$. Checking the options, we find that $(a, b) = (2, -4)$ satisfies the condition since $2(2)(-4) = -16$.
To determine the value of $k$, substitute the values of $a$ and $b$ into the perfect square trinomial form.
The perfect square trinomial form is $(ax + b)^2 = (2x - 4)^2 = 4x^2 - 16x + 16$.
We can see that $k = 16$ by comparing the derived form to the supplied trinomial $9x2 - 16x + k$.
As a result, $k$ has a Perfect Square Trinomial value of 16.

Mr. avola is deciding which of these packages of cheese to buy (package 1: SLICED cheese 12oz for 3 dollars) (package 2: BLOCK of cheese 1.5lbs for 5.52 dollars) which package cost less per ounce?
Answer:
Package 2
Step-by-step explanation:
Mr. avola is deciding which of these packages of cheese to buy
For Package 1
Package 1: SLICED cheese 12oz for 3 dollars
12oz = 3 dollars
1 oz = x
Cross Multiply
12 oz × x = 3 × 1 oz
x = 3 × 1 oz/12 oz
x = 0.25 dollars
Hence, Package 1 cost 0.25 dollars per ounce
For Package 2
Package 2: BLOCK of cheese 1.5lbs for 5.52 dollars.
We convert Ibs to oz
1 Ibs = 16 oz
1.5 Ibs = x
x = 1.5Ibs × 16 oz/1 Ibs
x = 24 oz
Hence:
24oz = 5.52 dollars
1 oz = x
Cross Multiply
24 oz × x = 5.52 × 1 oz
x = 5.52 × 1 oz/24oz
x = 0.23 dollars
Package 2 cost 0.23 dollars per ounce
Therefore, the package that cost less per ounce is Package 2

x=28
Step-by-step explanation:
4(x-5)=92
4x-20=92
add 20 to both sides
4x=112
divide 4 on both sides
x=28
Answer:
The value of x is 28
Step-by-step explanation:
4(x - 5) = 92
4x - 20 = 92
4x = 92 + 20
4x = 112
x = 112 ÷ 4
x = 28

the thomas family had an opportunity to by 50 acres of land for $800 per acre. in the past the price of land had risen 3% per year. how long will it be before the land is worth $1000 per acre? explained
Given:
Initial value = $800 per acre
Growth rate = 3% per year
To find:
How long will it be before the land is worth $1000 per acre.
Solution:
The exponential growth model is:
[tex]y=a(1+r)^t[/tex]
Where, y is the new value, a is the initial value, r is the growth rate in decimal and t is the number of years.
Putting [tex]y=1000, a=800, r=0.03[/tex], we get
[tex]1000=800(1+0.03)^t[/tex]
[tex]\dfrac{1000}{800}=(1.03)^t[/tex]
[tex]1.25=(1.03)^t[/tex]
Taking log both sides, we get
[tex]\log 1.25=\log (1.03)^t[/tex]
[tex]0.09691=t\log (1.03)[/tex]
[tex]0.09691=0.012837t[/tex]
Isolating the variable t, we get
[tex]\dfrac{0.09691}{0.012837}=t[/tex]
[tex]7.54927=t[/tex]
[tex]t\approx 7.55[/tex]
Therefore, the land is worth $1000 per acre after 7.55 years.
