To help divide a group into 4 teams, the teacher brought out a bag with equal numbers of 4 different colored popsicle sticks (green, yellow, blue, and red). With 28 students randomly picking a stick, what is the probability that the first stick drawn will be green? A. 0.250 B. 0.571 C. 0.036 D. 0.143
Answers
Ω = 24 ( 4*7 = 28 stick)
set of events favorable A
A = 7 ( sticks of green is 7)
Probability P
P(A) = A/Ω = 7/28 = 1/4 = 0,25
Answer A

Answer:
Volume of the cylinder (V) is given by:
where
r is the radius of the cylinder
h is the height of the cylinder.
As per the statement:
34 m on top and 27 m down on the right.
⇒Diameter(d) = 34 m and Height(h) = 27 m
We know:
Diameter = 2(radius)
⇒
Divide both sides by 2 we have;
m
Substitute these given values in [1] we have;
⇒
Simplify:
V = 24,501.42 cubic m.
Therefore, volume of the cylinder is, 24,501.42 cubic m.
The required volume of the cylinder is 24501.4 cubic meters
Use the concept of the cylinder defined as:
In mathematics, a cylinder is a three-dimensional solid that maintains, at a given distance, two parallel bases connected by a curving surface.
These bases often have a circular form (like a circle), and a line segment known as the axis connects the centers of the two bases.
Given that,
Height of cylinder 'h' = 27m
Diameter = 34 m
Since radius = diameter/2
Therefore, Radius 'r' = 17 m
We know that,
The volume of a cylinder,
V = πr²h
Put the values in this formula we get,
V = 17²(27)π
V = 24501.42 m³ [since π = 3.14]
Hence,
The volume of the cylinder is 24501.4 cubic meters.

Answer:
m=-16
Step-by-step explanation:
To solve the equation, we want to find out what m is. In order to do this, we have to get m by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.
-35=m-19
19 is being subtract from m (-19). The opposite of subtraction is addition. Add 19 to both sides (+19) The -19 and +19 equal 0, and therefore cancel each other out.
-35+19=m-19+19
-35+19=m
-16=m
Let's check our solution. Plug -16 back in for m in the original equation.
-35=m-19
-35=-16-19
-35=-35
Both sides of the equation are the same, so we know that m is equal to -16.
1 . What is the mean of the data set?
Answers
average= total number/number of objects or numbers
so the answer is 393, 399, 402,402,407, 410, 424, 425, 428 all added together then divided by 9
if we use a calculator to add them up we get 3690
then divide by 9
3690/9=410
410 is the mean
in the firs row there is 39 | 3 9 which means there are items 393 and 399,
to calculate sum i may write 393 + 399, or 3 + 9 + 39*2*10 which i find easier to calculate
sum = 3 + 9 + 2 + 2 + 7 + 0 + 4 + 5 + 8 + (2*39 + 3*40 + 1*41 + 3*42)*10 = 40 + (78+120+41+126)*10 = 40 + 3650 = 3690
mean = sum / number of items = 3690 / 9 = 410
