Two coins are flipped. Draw a sample space diagram showing all possible outcomes

1 answer:

7 0

H = Heads, T = tails
1st Coin 2nd Coin Final Outcome, ÷ 4 possible outcomes
H (H,H) 1/4, or 25%
H
T (H,T) 1/4, or 25%

H (T,H) 1/4, or 25%
T
T (T,T) 1/4, or 25%

If order does not matter:
T,T: 25%
TH or HT: 50%
HH: 25%

What is the median to -4 -6 0 -1 -1 -0

elena-14-01-66 [18.8K]

Answer:

-0.5 is the answer

Step-by-step explanation:

ARRANGING THE VALUE IN ASCENDING ORDER

-6,-4,-0,-1,-1,0

N=6(counting the above numbers of ascending order)

Position of median=(N+1/2)th items

=(6+1/2)th items

=(7/2)th items

=(3.5)th items

IF THE ANSWER IS IN POINT YOU SHOULD FIND THE AVERAGE,

3.5th itemsis the average of 3rd and 4th items

Median=-0+(-1)/2

=-0-1/2

=-1/2

=-0.5

Hope it us helpful for you

Miguel has 48 coins.of the 48 coins 5/8 are dimes.how many of the coins are dimes

Ivahew [28]

A simple way you could solve this is by drawing a tape graph.
Draw a long rectangular box.
Cut the box into 8 pieces, seeing as how 5/8 of the coins are dimes.
We have to take 48 and divide it by 8, we get 6, so now we know how many dimes are evenly split into each piece.
Now color in 5 pieces of the tape.
This represents the 5 in 5/8.
Now to find the number of coins, simply multiply 5 by 6, you get the answer of 30.
I hope this helps, if you are confused with any part of my explanation, ask and I will clarify.

Answer:

Option B 1 : 3

Step-by-step explanation:

Volume formulas & definitions:

To solve this problem, we must remember the formulas for volume of each shape:

$V_{cylinder}=\pi r^2h\\V_{cone}=\frac{1}{3} \pi r^2 h$ where r represents the radius of the circular part of the shape, and h represents the height of the shape (the plural of height is "heights", and the plural of radius is "radii")

So, when the question states that the shapes "have congruent heights and radii" it means that the height of both objects is the same, and the radius of both objects is the same.

Ratios

To find the ratio of the volume of the cone to the volume of the cylinder, we must setup the ratio. Ratios can be setup as a fraction where the first quantity is the numerator (top of fraction), and the second quantity is the denominator (bottom of the fraction):

$\dfrac{V_{cone}}{V_{cylinder}}=\dfrac{\frac{1}{3} \pi r^2 h} {\pi r^2 h}$

Since the pi, the "r", and the "h" are the same in both the numerator and denominator (and since there is only multiplication & division in the fraction) these common factors can cancel, and reduce the fraction to the following:

$\dfrac{V_{cone}}{V_{cylinder}}=\dfrac{\frac{1}{3}} {1}$

Any number divided by 1 doesn't change, so one-third divided by 1 is still one-third.

$\dfrac{V_{cone}}{V_{cylinder}}=\frac{1}{3}$

Other representations of ratios

Lastly, we must remember that a ratio an also be written with a colon symbol, where the numerator is written first, and the denominator is written second.

So, the ratio of the volume of the cone to the volume of the cylinder is:

1 : 3
