I will mark brainiestttttt answeerr
Answer:
The mean of the data is 3 inches, is false
Step-by-step explanation:
3, 3, 4, 4, and 6 inches.
To find the mean, add the numbers together and divide by the number of data points
( 3+3+4+4+6)/5 = 20/5 = 4
The median is the middle number
3, 3, 4, 4, and 6 inches.
The median is 4
The range is the largest number minus the smallest number

Q: The ratio of the numbers of Nick's marbles to Michael's is 3:5. Nick has 36 marbles. If Nick receives
another 9 marbles, what will be the new ratio of the number of Nick's marbles to Michael's?
Answer:
[tex]\frac{3}{4}[/tex]
Step-by-step explanation:
[tex]\frac{3}{5} = \frac{36}{x}[/tex]
3x = 36 x 5
3x = 180
x = 60
Michael has 60 marbles.
Nick recieves 9 more marbles so he has 36 + 9 = 45 marbles
The new ratio will be:
[tex]\frac{45}{60}[/tex] = [tex]\frac{3}{4}[/tex]

3.14*r^2= area
3.14*1.2^2=4.52
5.40*4.52=24.42
Answer:
Step-by-step explanation:
Remark
First find the area of the circular piece of fabric. Then deal with cost per square foot.
Area of the fabric
Area = pi * r^2
Area = 3.14 * 1.2^2
Area = 3.14 * 1.44
Area = 4.5216 square feet
Cost
1 square foot costs 5.40 dollars
4.5216 square feet costs x Cross multiply
x = 5.40 * 4.5216
Answerx = 24.42 dollars for the fabric bought.
A triangle is dilated by a scale factor of n = one-third. which statement is true regarding the dilation? it is a reduction because n > 1. it is a reduction because 0 < n < 1. it is an enlargement because n > 1. it is an enlargement because 0 > n > 1.
The second statement is true. It is a reduction because 0 < n < 1.
What is dilation?
Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.
Given: A triangle is dilated by a scale factor of n = 1/3. As n is less than 1 but greater than 0.
A dilation is a rigid transformation that forms an image that is the same shape as of the original figure but with a different size. A dilation transforms a figure by scalar factor 'n' about the center of dilation is a fixed point in the plane which never changes.
A dilation that forms a larger image is known as enlargement. A dilation that forms a smaller image is known as reduction.
• If n is greater than 1, then the image is an enlargement.
• If n is between 0 and 1, then the image is a reduction.
• If n is 1, the figure and then the image is exactly the same.
Hence the second statement is true. It is a reduction because 0 < n < 1.

B. 45
C. 100
D. 65
Answer:65
Step-by-step explanation:
Hi
It’s 65 bc 35+80= 115. And triangles are 180° so 115-180= 65.
Hope it helped
Answer:
65
Step-by-step explanation:
The value of 35 degrees can be translated from the opposite diagonal. Adding the 80 degrees and 35 degrees equals 115 degrees. Finally find the remainder 180-115= 65
You roll a die repeatedly, stopping when you roll a 1. Your score is the sum of values of all your rolls. What is the expected score
Using the binomial distribution, it is found that the expected score of the game is of 21.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The expected number of trials until q successes is:
[tex]E_s(X) = \frac{q}{p}[/tex]
In this problem, a die has a p = 1/6 probability of resulting in a 1, hence the expected number of trials is:
[tex]E_s(X) = \frac{1}{\frac{1}{6}} = 6[/tex]
In each trial, each outcome from 1 to 6 is equally as likely, hence the expected score of a single trial is given by:
[tex]E = \frac{1 + 6}{2} = 3.5[/tex]
Then, the expected score of the six trials is:
6 x 3.5 = 21.

Derek is hang gliding on a clear day at an altitude of a feet. His visibility, v, is 67.1 mi. Use the formula v = 1.225 to find the altitude at which Derek is hang gliding.
Step-by-step explanation:
since the equation is v = 1.225 × sqrt(a)
we can plug in the known values to find the altitude.
so:
(67.1/1.225)^2 = a
a = 3000
Base on the visibility formula v = 1.225√a, the altitude at which Dereck is hang gliding is 7.4 miles
How to find altitude using visibility formula?The visibility formula is given as follows:
v = 1.225√a
where
a = altitudev = visibilityTherefore,
v = 67.1 miles
v = 1.225√a
67.1 = 1.225√a
divide both sides by 1.225
√a = 67.1 / 1.225
√a = 54.7755102041
square both sides
√a² = √54.7755102041
a = 7.40104789878
a = 7.4 miles

Answer:
x = y = 64° , z = 20°
Step-by-step explanation:
x = y = [tex]\frac{180-52}{2}[/tex] = 64 °
m∠ADC = 52° + x
m∠ADC = 52° + 64° = 116°
z = 180° - 116° - 44° = 20 °
Mr. Jones sold two pipes at $1.20 each. Based on the cost, his profit one was 20% and his loss on the other was 20%. On the sale of the pipes, he:
(a) broke even,
(b) lost 4 cents,
(c) gained 4 cents,
(d) lost 10 cents,
(e) gained 10 cents
two pipes= $1.20
solution:Selling price of the first pipe = $1.20
Profit = 20%
Let’s try to find the cost price of the first pipe
CP = Selling price - Profit
CP = 1.20 - 20% of CP
CP = 1.20 - 0.20CP
CP + 0.20CP = 1.20
1.20CP = 1.20
CP = 1.20/1.20
CP = $ 1
Selling price of the Second pipe = $1.20
Loss = 20%
Let’s try to find the cost price of the second pipe
CP = Selling price + Loss
CP = 1.20 + 20% of CP
CP = 1.20 + 0.20CP
CP - 0.20CP = 1.20
0.80CP = 1.20
CP = 1.20/0.80
CP = $1.50
Therefore, total cost price of the two pipes
= $1.00 + $1.50
= $2.50
And total selling price of the two pipes
= $1.20 + $1.20
= $2.40
Loss = $2.50 – $2.40 = $0.10
Therefore, Mr. Jones loss 10 cents.

A waitress earned a 18% tip.What decimal is equivalent to 18%
0.18
Step-by-step explanation:Percentages and decimals are closely related. As a matter of fact, we don't need to use any actual math to solve this question because there is a shortcut.
Answer by Dividing
One way to solve the question is by dividing. Percentages are numbers that represent a portion of 100. So, to find the decimal form we can divide the percentage by 100.
18/100 = 0.18Shortcut
While dividing by 100 can work, there is an easier way to find the decimal form. Dividing by 100 will always be equivalent to moving the decimal point 2 digits to the left.
This means that 18.0 becomes 0.18 when using this shortcut.A closed cylinder has how many faces ?

What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, Tristan paid $37.70 for 5 books by his favorite author.
Each book would have cost $9 if he had purchased it online instead.
Total money paid to purchase books online = 5×9
= $45
Difference in cost = 45-37.70
= $7.3
Therefore, Tristan would have paid $7.3 more, if he had purchased the books online.

The function in vertex form is equivalent to [tex]\rm y = (x + 2/4)^2 + \frac{3}{4}[/tex].
What are quadratic equations?A quadratic equation is an equation of degree 2 in other words.Quadratic equations have the form ax² + bx + c = 0 and are second-degree algebraic expressions.
The standard quadratic function with vertex (h, k) is ;
[tex]\rm y = a(x - h)^2 + k[/tex]
The general quadratic equation is found as;
[tex]\rm y = ax^2 + bx + c[/tex]
The value of h is given as;
[tex]\rm h = \frac{-b}{2a}[/tex]
For the given equation in the problem;
[tex]\rm y = x^2 + x + 1[/tex]
The value of the k is found by;
[tex]\rm y =( \frac{-1}{2}) ^2 - \frac{1}{2} + 1 \\\\ y= \frac{1}{4} - \frac{1}{2}+ 1 \\\\ y= \frac{1}{4}- \frac{2}{4}+ \frac{4}{4}\\\\ y= \frac{3}{4}[/tex]
So the vertex is at [tex]\frac{-2}{4}[/tex] and [tex]\frac{1}{4}[/tex] then the vertex form is:
[tex]y = (x +\frac{2}{4} )^2 + \frac{3}{4}[/tex]
Hence the functions in vertex form are equivalent [tex]\rm y = (x + 2/4)^2 + \frac{3}{4}[/tex].
