The scatterplot shows the number of cars and trucks sold by 10 differentemployees at a car and truck dealership during a month.How many employees sold more trucks than cars?
Let's us tabulate the data that is on the scatterplot.
As you can see in the fourth column, "Sold More Trucks than Cars?", some rows say "Yes" and some say "No".
Let's take a look at Employee No.1. Employee No.1 sold 4 trucks and sold 2 cars. Therefore, employee no.1 was able to sell more trucks than cars and thus, the answer to the fourth column is "Yes."
The same is done for all the employees.
In the end, there are 6 employees who were able to sell more trucks than cars.

Given a pair of points on each line, use the slope formula to determine whether AB and CD are parallel. perpendicular, or neither. AB: A(-2,-5) and B(4.7) CD: C(0, 2) and D(8,-2)
Answer:
Perpendicular
Explanation:
Given the coordinates
A(-2,-5), B(4.7) C(0, 2) and D(8,-2), we are to determine whether AB is parallel, perpendicular to CD or neither
To do this, we need to find he slope of AB and CD first. Using the formula for calculating slope as shown;
m = y2-y1/x2-x1
For AB:
slope = 7-(-5)/4-(-2)
Slope = 7+5/4+2
Slope of AB = 12/6
Slope of AB = 2
For CD
Slope of CD = -2-2/8-0
Slope of CD = -4/8
Slope of CD = -1/2
Note that for AB to be perpendicular to CD, the product of their slope must be -1.
Given
mAB = 2
mCD = -1/2
Taking their product
mAB * mCD = 2 * -1/2
mAB * mCD = -1
Since the product is -1, hence AB is PERPENDICULAR to CD

What is the probability of spending between 3.5 and 4.3 days in recovery? []f. The 85th percentile for recovery times is []
Part B
What is the median recovery time?
Remember that
For a normal distribution, mean = median = mode
so
The median is 4 days
Part C
What is the Z-score for a patient that took 5.7 days to recover?
Remember that
z =(x - μ)/σ
where
μ=4 days
σ=1.6 days
X=5.7 days
substitute
z=(5.7-4)/1.6
z=1.0625
Part D
What is the probability of spending more than 4.5 days in recovery?
z =(x - μ)/σ
μ=4 days
σ=1.6 days
x=4.5 days
Find out z
z=(4.5-4)/1.6
z=0.3125
using a z-score table values
P(X>4.5)=0.3773
Part E
What is the probability of spending between 3.5 and 4.3 days in recovery?
For x=3.5 -------> z=(3.5-4)/1.6=-0.3125
For x=4.3 -----> z=(4.3-4)/1.6=0.1875
using a z-score table values
P(3.5 < X < 4.3)=0.1970
Part F
Remember that
If your score is in the 85th percentile, it means that 85% of the scores are below your score and 15% are above your score
using a z-score table values
the value of Z=1.036
Find out the value of x
1.036=(x-4)/1.6
solve for x
x=5.6576 days

x is case of almonds and y is case of walnuts.
Almonds are packaged 15 bags per case and walnuts are packaged 17 bags per case.
H-E-B orders no more than 200 bags of almonds and walnuts at a time.
So,

H-E-B pays $24 per case of almonds and $27 per case of walnuts, but will not order more than $300 total at any one time.
But keep in mind that : Almonds are packaged 15 bags per case and walnuts are packaged 17 bags per case.

3 What is the length of the missing leg? 15 m I meters
Answer
The length of the missing leg = 12 m
Explanation
The triangle presented is a right angled triangle because one of its angles is equal to 90 degrees.
The Pythagorean Theorem is used for right angled triangle, that is, triangles that have one of their angles equal to 90 degrees.
The side of the triangle that is directly opposite the right angle or 90 degrees is called the hypotenuse. It is normally the longest side of the right angle triangle.
The Pythagoras theorem thus states that the sum of the squares of each of the respective other sides of a right angled triangle is equal to the square of the hypotenuse. In mathematical terms, if the two other sides are a and b respectively,
a² + b² = (hyp)²
For this question,
Hypotenuse side = 15 m
a = 9 m
b = d = ?
a² + b² = (hyp)²
9² + d² = (15)²
81 + d² = 225
d² = 225 - 81
d² = 144
d = √144
d = 12 m
Hope this Helps!!!
Answer:
We'd use the pythagorean theorem to solve for the other leg's length. As the image suggests, we'd use the theorem,
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
If one leg is 9 , that's our a value.
If the hypotenuse is 15 , that's our c value.
Now we just have to find the b value.
Plugging in the variables,
[tex] {9}^{2} + {b}^{2} = {15}^{2} [/tex]
[tex] {9}^{2} = 81 \\ {15}^{2} = 225 \\ 81 + {b}^{2} = 225[/tex]
Subtract 81 from both sides.
[tex] {b}^{2} = 144[/tex]
Square root both sides.
[tex] \sqrt{ {b}^{2} } = b \: and \: \sqrt{144 = 12 } [/tex]
so b = 12
