Answer:
10.34% probability that you both pick chocolate
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, it is not important if you or your friends picks first. So we use the combinations formula to find the number of desired and total outcomes.
Combinations Formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Desired outcomes:
10 are filled with chocolate, and we want to pick 2. So
[tex]D = C_{10,2} = \frac{10!}{2!(10-2)!} = 45[/tex]
Total outcomes:
The box has 30 chocolates, and 2 are picked, so:
[tex]T = C_{30,2} = \frac{30!}{2!(30-2)!} = 435[/tex]
Probability:
[tex]P = \frac{D}{T} = \frac{45}{435} = 0.1034[/tex]
10.34% probability that you both pick chocolate

A cylindrical tube 9.5 cm high and 0.85 cm in diameter is used to collect blood samples. How many cubic decimeters (dmଷ ) of blood can it hold (V = πrଶh)?
Answer: 0.539 cubic decimeters of blood can be hold by the cylinder.
Step-by-step explanation:
Volume of cylinder= volume of blood it can hold = [tex]\pir^2h[/tex]
Given :
Height of cylinder (h) = 9.5 cm
Diameter of cylinder (d) = 0.85 cm
Thus radius of cylinder (r) = [tex]\frac{\text {Diameter of cylinder}}{2}=\frac{0.85cm}{2}=0.425cm[/tex]
Putting the values we get:
Volume of cylinder= volume of blood it can hold = [tex]3.14\times (0.425cm)^2\times 9.5cm=5.39cm^3=0.539dm^3[/tex] [tex] (1cm=0.1dm)
Thus 0.539 cubic decimeters of blood can be hold by the cylinder.

The measurements of 100 products from the assembly line show that 99% are correct. Is this percentage a parameter or a statistic and why
Answer:
The percentage is a statistic, because it is a mesure of the sample.
Step-by-step explanation:
The difference of statistic and parameter is given by:
Statistic is a measure of the sample.
Parameter is a measure of the population.
In this question, we have that:
The measurements of 100 products from the assembly line show that 99% are correct.
This is the percentage from a sample of 100 products, not from an entire population, so the percentage is a statistic.

The volume of a cube is related to the area of a face by the formula V = A^3/2What is the volume of a cube whose face has an area of 100 cm??
helppp!!
Answer:
[tex]\huge\boxed{1000 \ \text{cm}^3}[/tex]
Step-by-step explanation:
There are two ways we can solve this equation.
A) Using the formula providedThe formula provided states that the volume of a cube based on the area of one of it's faces will be [tex]a^{\frac{3}{2}}[/tex], a the area of one face. Since we know the area of one face, we can substitute that inside the equation.
[tex]100^{\frac{3}{2}}[/tex]
It's important to note that when we have a number to a fraction power, it's the same as taking the denominator root of the base to the numerator power.
So - [tex]100^{\frac{3}{2}}[/tex] becomes [tex]\sqrt{100^3}[/tex]
[tex]100^3=1000000[/tex] [tex]\sqrt{1000000}=1000[/tex]Therefore, the volume of this cube will be [tex]1000 \ \text{cm}^3[/tex]
B) Using prior knowledge about cubesWe can additionally use prior knowledge to find the volume of this cube.
We know that the area of a square will be [tex]s^2[/tex], where s is the length of a side. We also know the formula to find the volume of a cube from it's side length is [tex]s^3[/tex].
Since we know that one face is 100, we can make an equation - [tex]s^2=100[/tex]
[tex]\sqrt{s^2}=\sqrt{100}[/tex] [tex]s=10[/tex]Now that we know the value of s, we can plug it into the volume formula, [tex]s^3[/tex].
[tex]10^3[/tex] [tex]10 \cdot 10 \cdot 10[/tex] [tex]1000[/tex]So the volume is [tex]1000 \ \text{cm}^3[/tex].

Over what interval(s) is the function strictly linear? Look at the picture. Don't Answer If You Don't Know What The Answer Is Please. Will Mark Brainliest.
Answer:
The answer is given by option c.
Step-by-step explanation:
Linear function:
The graphic of a linear function is a straight line.
In this question:
We have a straight line for x between -2 and 0, so in this interval the function is linear.
For x between 0 and 2, the function is a curved line, so not linear in this interval.
We also have a straight line for x between 2 and 4, so in this interval the function is linear.
So it is linear in the following intervals: -2 < x < 0, 2 < x < 4, so the answer is given by option c.

Find the parametric equations for the line that is tangent to the given curve at the given parameter (3cost)i (t^4 -3sint)j
Answer:
Following are the solution to this question:
Step-by-step explanation:
Please find the complete question in the attached file.
In the given equation, when the point t=0
So,
[tex]\to r(0) = (3 \cos 0)i + (0^4 - 6 \sin 0)j + (2e^{3\times 0})k)[/tex]
[tex]= (3 \times 1)i + (0 - 0)j + (2e^{0})k)\\\\ = 3i + 0j + (2 \times 1)k)\\\\ = 3i + 0j + 2k \\[/tex]
The value of the coordinates are [tex]3, 0, 2[/tex] . so, the equation of the line is:
[tex]\to \frac{(x-3)}{3 \cos \ t} = \frac{(y-0)}{(t^{4}-6 \sin \ t)} = \frac{(z-2)}{2e^{3t}}=k[/tex]
Please help with A through D
Answer:
A. 6.466
B. 6
C. 5
D. 30 nominations
Step-by-step explanation:
A. The mean is all of the numbers added together, and divided by how many numbers there are, so take all of the numbers, which end up being added up to 97, and then divide by 15, because that´s how many numbers there are, you end up getting 6.46666 and you round it to 6.466
B. The median is when you take all of the numbers and put them into order, and then find the number in the exact middle of all of the numbers, so the numbers were 4 5 5 5 5 5 5 6 6 7 7 8 8 9 12, the middle number was 6
C. The mode is the number that appears the most, and that would be 5
D. The most reccuring number is 5, and if you take that and multiply it by how many times it is shown, 6, you get 30

Which decimal is equivalent to 19/50
how many miles would it be ??
help I need help pleaseee
Answer:
The perimeter of a rectangle is the sum of twice the length and twice the width. If the perimeter is at least 48 cm, then the minimum perimeter is 48 cm.
Let width = x
Let length = x + 4
Perimeter = 48
We can set an inequality for perimeter using the variables.
2x + 2(x + 4) ≥ 48
Solve for x.
2x + 2x + 8 ≥ 48
4x + 8 ≥ 48
4x ≥ 40
x ≥ 10
Substitute this value of x into the variable to get your width and length.
width = 10 cm
length = 14 cm

Can someone answer this and then teacher me how I can do more like this in the future?
Answer:
15²+40²=42.72
Step-by-step explanation:
In this particular problem, you can use pythagorean theorem. The pythagorean theorem consists of the formula a²+b²=c². This theorem is mostly used when solving for the hypotenuse in a right triangle.
In this problem,
a=15
b=40
c=? (this is the hypotenuse)
then, plug the numbers into the formula
a²+b²=c²
15²+40²=?
15²=225
40²=1600
1600+225=1825
or you could just punch the numbers in a calculator
then take the square root of 1825 to find your answer
√1825=42.72

A total of 937 people attended the play. Admission was $2.00 for adults and $0.75 for students. The total ticket sales amounted to $1,109. How many students and adults attended the school play? First complete the equations below, where A stands for Adults and S stands for Students. 2A + 0.755 = 1,109; A + S = 937 Now use the equations to find the number of students and adults. Students = [?]; Adults = [ ]
Answer:
612 students and 325 adults.
Step-by-step explanation:
To determine the number of adults and students who attended the event, knowing that in total there were 937 people who spent a total of $ 1,109 and that each student ticket is worth $ 0.75 while each adult ticket is worth $ 2, the following logical reasoning must be performed:
2 - 0.75 = 1.25
Therefore, the minimum that each ticket will be worth is $ 0.75, while there will be a surplus of money that will be divisible by 1.25, which is the amount of more that each adult paid on their ticket.
Therefore, since 0.75 x 937 equals 702.75, the total price surplus is 406.25 (1,109 - 702.75). Now, this number divided by 1.25 gives a total of 325, with which 325 adults attended the event. In turn, given that the total number of attendees was 937, the total number of students who attended the event is 612 (937 - 325).
