Julie bought a shirt for $35.00, a purse for $27.00 and a belt for $13.00. When the cashier rang up her total, she discovered everything was on sale for 30% off. What was Julie's total with the sale price?
Answer: 52.5
Step-by-step explanation:
35 dollars 30% off is $24.5, 27 dollars 30% off is $18.90, and 13 dollars 30% off is $9.10 so all together it equals 52.5.
When discordant pairs exceed concordant pairs in a P-Q relationship, Kendall's tau reports a(n) ________ association between the variables under study.a. positive.
b. weak.
c. negative.
d. strong.
e. inverse.
Answer:
a. positive.
Step-by-step explanation:
Matching and discordant pairs are used to describe the relationship between pairs of observations. To calculate matched and discordant pairs, data is treated as ordinal values. Therefore these are suitable for your application. The number of concordant and discordant pairs is used in Kendall's tau calculations, whose purpose is to determine the relationship among two ordinal variables.
If the direction of the classifications is the same, the pairs are concordant.
A pair of observations is discordant, suppose the subject being with an increased value on one variable is lower on the other.
SO; When discordant pairs exceed concordant pairs in a P-Q relationship, Kendall's tau reports a(n) positive association between the variables under study.

Simplify the expression 10a-7b+11+8b-b-12
Answer:
10a-16b+23
Step-by-step explanation:
First, you see what terms are alike. Then you add those like terms. For example with this expression, you add 7b+b+8b, resulting in 16b. If you are confused by the single b variable standing alone, there is basically a 1 in front of it, so you add it as 1b. 11 and 12 are like terms, for they don't have any variables attached to them. 10a stands alone because no other terms have an a variable. The simplified expression is 10a-16b+23.
Your welcome <3
The simplified value of the expression 10a - 7b + 11 + 8b - b - 12 is 1a - 1.
Given Expression:
10a-7b+11+8b-b-12
To simplify expression, first solve the like terms as
10a-7b+11+8b-b-12
= 10a -7b + 8b - b - 12 + 11
Now, -7b + 8b - b = -7b + 7b = 0
and, -12 + 11 = -1
Substituting the simplified value in 10a-7b+11+8b-b-12 gives
= 10a + 0 - 1
= 10a - 1

Given: △ABD cong △CBD. Find each value. (#6)
Answer: m<C= 31
Step-by-step explanation:
To find m<C: Since the triangles are equal, we know that (4x+10) is equal to 90. Then when you put them equal to each other and solve for x you get X=20. Then all you have to do is plug that x value (20) into the equation for the angle of C (x+11). Then you get that C=31 degrees.

Michaela solved a system of linear equations that had no solution. One of the equations was x + y = 5. The other equation had a y-intercept of −2. What was the other equation?
Answer:
We have a system of equations with no solutions.
One of the equations is:
x + y = 5.
Isolating y in one side of the equation, we get:
y = 5 - x
And the other equation has an y-intercept of -2, the equation can be written as:
y = a*x - 2.
Then the system will be:
y = -1*x + 5
y = a*x - 2
The solution of a system of equations is a point where the graphs of both functions intersect.
Then if both of these lines are parallel, the lines will never intersect, then the second equation must be parallel to the first one.
And two lines are parallel if they have the same slope.
Then the other equation will be:
y = -x - 2

y-2=-1/5(x+3) is the point-slope form of the equation below that represents the line that passes through the points (-3, 2) and (2, 1).
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given two points are (-3, 2) and (2, 1)
m=1-2/2+3
=-1/5
So slope is -1/5.
Now let us find the point slope form
y-y₁=m(x-x₁)
y-2=-1/5(x+3)
Hence, y-2=-1/5(x+3) is the point-slope form of the equation below that represents the line that passes through the points (-3, 2) and (2, 1).

How do you do 20 / 4/5
Answer:
25
Step-by-step explanation:
you can write this equation as 20 ÷ [tex]\frac{4}{5}[/tex]
so change the division sign to multiplication by flipping the divisor ( [tex]\frac{4}{5}[/tex] )
this means you now have 20 x [tex]\frac{5}{4}[/tex]
so you can simplify 20 and 4, this makes the 4 into a 1 and the 20 into a 5
you now have 5 x [tex]\frac{5}{1}[/tex]
this is the same thing as 5 x 5
multiply it, and you can see that the answer is 25

Show how you found the slope and Y-intercept
Answer:
i. y=2x
ii. y=x+6
iii. y=-2x-6
iiii. y=-4x+3
iiiii. y=4x-3
Step-by-step explanation:
You can find the slope of the line by putting y2-y1/x2-x1
All you have to do is choose 2 points. Y2 is the second number y and x2 is the second number x. Y1 is the first number y and X1 is the first number X. To find y-intercept you look on the table and see where X is 0 and Y is any number that is the y-int. For example 5 there is no X=0 on the table so you put it in the point slope formula which is y-y1=m(x-x1) where you use the points from the slope. You multiply m to x and m to x1 where you will end up with y-y1=mx+mx1 then you add the y1 to mx1 where you will get the y intercept

Maria and Sarah were in charge of selling tickets to the class play. Maria sold 91
tickets and Sarah sold 70 tickets. What is the ratio of the number of tickets Maria sold
to the total number of tickets sold?
Answer:
Maria sold 56.5% of the total quantity of tickets sold.
Step-by-step explanation:
Given that between Maria and Sarah they both sold 161 tickets (91 + 70), and that of those 161 Maria sold 91 while Sarah sold 70, to determine the percentage of tickets that Maria sold over the total amount, the following crossed multiplication must be performed:
161 = 100
91 = X
((91 x 100) / 161) = X
9,100 / 161 = X
56.5 = X
Therefore, Maria sold 56.5% of the tickets sold.
If a fair coin is tossed 9 times, what is the probability, to the nearest thousandth, of
getting exactly 4 tails?
Answer:
=0.444

total outcome 9
4 into decimal = 0.444( to the nearest thousandths- 3dp)
9
The probability is 24.609%
What is probability?The mathematical subject of probability deals with the outcomes of random events. The term "probability" refers to the possibility or chance of an outcome. It clarifies the likelihood of a particular occurrence. We use phrases like "It will probably rain today," "he will probably pass the test," "there is very little chance of getting a storm tonight," and "most probably the price of onion will go high again" all the time.
Given a coin is tossed 9 times, and to find the probability of exact four heads,
the probability for condition given by binomial probability ⁿCₓ[(p)ˣ(q)ⁿ⁻ˣ]
where p is probability of tail = 1/2 (favorable outcome)
q is probability of head = 1/2: (1 - p)
n = total outcome = 9
x = 4
ⁿCₓ[(p)ⁿ(q)ⁿ⁻ˣ] = ⁹C₄[(1/2)⁴(1/2)⁵]
= [tex]\frac{9!}{4!(9 - 4)!}[/tex] [1/16 x 1/32]
= [tex]\frac{9 x 8 x7 x 6 x 5!}{4! x 5!}[/tex](512)
126/512 = 0.24609
= 24.609%
Hence the probability, to the nearest thousandth is 24.609%.

Answer: B) Linear; it can be written as y = -3x-6
We subtract 6 from both sides to go from the original equation to -3x-6 = y
Then we flip both sides to end up with y = -3x-6
This is in slope intercept form y = mx+b with m = -3 as the slope and b = -6 as the y intercept.
