Answer:
[tex]P(Not\ 3) = \frac{5}{6}[/tex]
Step-by-step explanation:
Given
[tex]S = \{1,2,3,4,5,6\}[/tex] --- sample space
Required
P(not 3)
First, we list out all outcomes that are not 3.
We have:
[tex]Not\ 3 = \{1,2,4,5,6\}[/tex] --- 5 possible outcomes
[tex]S = \{1,2,3,4,5,6\}[/tex] ---- 6 total outcomes
So, P(Not 3) is calculated as:
[tex]P(Not\ 3) = \frac{n(Not\ 3)}{n(S)}[/tex]
[tex]P(Not\ 3) = \frac{5}{6}[/tex]
Answer: 5/6

Admission to the carnival is $10 plus $2 per ride. John spent $38 on admission and
rides. Write and solve an equation to find how many rides John went on.
Answer:
he went on 14 rides.
Step-by-step explanation:
take your total, 38, subtract that by 10 (because you have to pay the admission fee) and you have 28 dollars spent on rides. each ride costs 2 dollars so divide 28 by 2 and you get 14.

x = 44
A 88
B 48
C 44
Find the value of x
Answer:
x=135
Step-by-step explanation:
The two angles are supplementary, meaning they both add up to 180°.
So to find the value of one angle, simply subtract 50 from 180.
180-50=130
So now we know that 130 is equal to the expression.
x-5=130
Add 5 to both sides.
x=135

6 friends are selling crafts at a show. They each need to pay $7.20 to cover the table rental. They each sell 3 items. If every item is the same price, and the 6 friends make a total of $25.20, what was the sale price of each item?
Answer:
$1.00
Step-by-step explanation:
The sales price of the items sold by the 6 friends given the total amount made is $1.40.
What is the sales price?In order to determine the sales price, divide the total amount made by the total amount of the items sold
Sales price = $25.20 / (6 x 3) = $1.40

The Eagle Ridge Contractors Association claims the average price of a home in their subdivision is $125,150 with a standard deviation of $7,350. A sample of 36 homes for sale in this subdivision had an average selling price of $123,550. The Eagle Ridge Home Owners Association is interested in knowing if the costs of homes for sale in this subdivision are actually lower than claimed? Compute the test value.
Answer:
The test value is z = -1.31.
Step-by-step explanation:
The Eagle Ridge Contractors Association claims the average price of a home in their subdivision is $125,150.
This means that the null hypothesis is that the mean is this value, that is:
[tex]H_0: \mu = 125150[/tex]
The Eagle Ridge Home Owners Association is interested in knowing if the costs of homes for sale in this subdivision are actually lower than claimed.
This means that at the alternate hypotehsis we test that the mean is lower than that value, that is:
[tex]H_a: \mu < 125150[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
125150 is tested at the null hypothesis:
This means that [tex]\mu = 125150[/tex]
Standard deviation of $7,350.
This means that [tex]\sigma = 7350[/tex]
A sample of 36 homes for sale in this subdivision had an average selling price of $123,550.
This means that [tex]n = 36, X = 123550[/tex]
Compute the test value.
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{123550 - 125150}{\frac{7350}{\sqrt{36}}}[/tex]
[tex]z = -1.31[/tex]
The test value is z = -1.31.

Jolie manages an annual film festival in her town. Every year, one movie from every genre is chosen as a finalist to win best film. The following double bar graph represents the votes each film received by adults and children. Answer the following questions based on the data in this bar graph.
⦁ What percentage of children voted for the Action movie? Show your work. Round to the nearest percent if needed.
⦁ Which movie received 20% of the total votes? Show your work.
Answer:
• 25%
• Drama movie
Step-by-step explanation:
• Total number of children
= 16 +12 +18 +20 +14
= 80
Percentage of children that voted for action movie
[tex] = \frac{no. \: of \: children \: that \: voted \: for \: action \: movie}{total \: number \: of \: children} \times 100\%[/tex]
[tex] = \frac{20}{80} \times 100\%[/tex]
[tex] =\textbf{25\%}[/tex]
------------------------------------------------------------
• Total number of votes
= 30 +32 +36 +36 +26
= 160
20% of total votes
= 20% ×160
= 32 votes
Since Drama movie received 32 votes, it received 20% of the total votes.

Ling and her family ordered takeout that cost $50. Ling paid 4% sales tax and left a 10% tip
Answer:
$47
Step-by-step explanation:
Given data
Cost= $50
Tax= 4%
Tip= 10%
Let us find the amount of the Tax
=4/100*50
=0.04*50
=$2
Let us find the amount of the Tip
=10/100*50
=0.1*50
=$5
Hence the total amount is
=50+2-5
=52-5
=$47

what is the measure of angle KIT?
Answer:
80°
Step-by-step explanation:
In rhombus, opposite angles are equal. i.e <KET = <KIT
Triangle KET is isoceles, which means both parts of angle E are equal.
Angle E = 40 + 40
Angle E = 80
If angle E is 80 than Angle I is also 80.
find the area of a circle if its circumference is 10 pi
Answer:
25π
Step-by-step explanation:
pi's symbol is π, which will be used sometimes to make it easier later
The circumference is equal to diameter multiplied by pi. (Diameter is the length across the circle, radius the center of the circle to an edge point aka. half the diameter, and circumference is the edge length aka. perimeter of the circle.)
We can then remove the pi off the 10, as the diameter multiplied by pi is the circumference, so the diameter is 10.
Half of 10 is 5, the radius.
The formula for area of a circle is radius squared times pi, remember easily by π r ^2
We can plug in the radius into the formula to get
π 5 ^2
And finish it by solving the square root to get
π 25
25π

The r-value of the given data is 0.374.
What is a correlation coefficient?The correlation coefficient, denoted as r, is a statistical measure that describes the strength and direction of the linear relationship between two variables.
It ranges between -1 and +1, where -1 indicates a perfect negative correlation (inverse relationship), +1 indicates a perfect positive correlation (direct relationship), and 0 indicates no correlation between the variables.
We have,
First, we need to find the correlation coefficient (r) of the given data.
We can use the following formula to do this:
r = [n∑(xy) - (∑x)(∑y)] / [√{n∑x² - (∑x)²} √{n∑y² - (∑y)²}]
where n is the number of data points, x, and y are the respective variables, and ∑ denotes the sum of the values.
Using the given data, we can calculate the values as follows:
n = 5
∑x = 39
∑y = 53
∑(xy) = 442
∑x^2 = 483
∑y^2 = 1249
Substituting these values into the formula, we get:
r = [5(442) - (39)(53)] / [√{5(483) - (39)^2} √{5(1249) - (53)²}]
r = [2210 - 2067] / [√(2415) √(5660)]
r = 143 / (61.898 75.245)
r = 0.374 (rounded to three decimal places)
Therefore,
The r-value of the given data is 0.374.

through: (3,0), parallel to y = 2/3x+1
Answer:
y = 2/3x - 2
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is y = 2/3x + 1. Its slope is 2/3. A line parallel to this one will also have a slope of 2/3.
Plug this value (2/3) into your standard point-slope equation of y = mx + b.
y = 2/3x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (3, 0). Plug in the x and y values into the x and y of the standard equation.
0 = 2/3(3) + b
To find b, multiply the slope and the input of x (3)
0 = 2 + b
Now, subtract 2 from both sides to isolate b.
-2 = b
Plug this into your standard equation.
y = 2/3x - 2
This equation is parallel to your given equation (y = 2/3x + 1) and contains point (3, 0)
Hope this helps!
