What is the probability that if a coin lands on heads and the number cube shows 5
Answer:
Not sure
Step-by-step explanation:
Well I’m just guessing these numbers but…
For the coin it is one minus the probability of the coin landing on tails minus the tiny probability of the coin landing on its edge and balancing there. So something like (1 - 0.499 999 5 - 0.000 001), or 0.499 995; call it as near 0.5 as makes no difference.
For the number cube it is one minus the probability of the cube landing on one, three or five minus the tiny probability of the coin landing on an edge or the even tinier probability of it landing on a corner and balancing there. So something like (1 - 3 * 0.166 666 - 12 * 0.000 000 36 - 8 * 0.000 000 08) , or 0.499 998; call it as near 0.5 as makes no difference.
So the joint probability is the first probability times the second. So 0.5 * 0.5 which is 0.25 for all intents and purposes

Answer:
y = 5
Step-by-step explanation:
The equation for a line is y = mx + b, with m representing slope and b representing y-intercept.
This yields an equation y = 0x + 5, or just y = 5 when simplifying.

Write the standard form equation of each circle.
Center: (-11, -8) Radius: 4
Center: (-6, -15) Radius: square root of 5
Answer:
(x+11)^2 + (y+8)^2 = 4^2/16
(x+6)^2 + (y+15)^2 = 5
Step-by-step explanation:
the standard equation of a circle is
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
in the first equation -11 is h and -8 is k
so (x+11)^2 because when you subtract a negative the double negative creates a positive and that’s the same for (y+8)^2
so (x+11)^2 + (y+8)^2 = 4^2 or 16
in the second equations -6 is h and -15 is k
and the double negative is also effective in this equation so (x+6)^2 and (y+15)^2 therefore, (x+6)^2 + (y+15)^2 = 5 (the square root of 5 squared is just 5)
hope this helps :)

What is the area of the polygon?
Answer:
The answer is 34 m^2
Step-by-step explanation:
Well, we can divide the Polygon into pieces and solve the area for each piece.
There will be a rectangle and a trapezoid.
Area of Rectangle: Area = Length * Width
Area = Length * Width
Area = 6 m * 3 m = 18 m^2
Area of a Trapezoid: Area = [tex]\frac{h*(b1+b2)}{2}[/tex]
[tex]A=\frac{h*(b1+b2)}{2}\\A=\frac{4*(6+2)}{2}\\A=\frac{4*8}{2} \\A=\frac{32}{2} \\A=16 m^2[/tex]
Total Area = 16 m^2 + 18 m^2 = 34 m^2

Answer:
27, 5, 2
Step-by-step explanation:
This is really simple lol.
a. Simple Math terms
43 subtracted by 16 equals 27.
Let's do 46-16 which equals 30.
Subtract 3 from 30.
43-16=27.
a. Mathematical
43-16 = . . .
13 - 6 = 7
Subtract the 1 from 4.
3 - 1 = 2
43-16=27.
b. Simple Math terms
67-14=53
7-4 = 3
6-1=5
c. Simple Math terms
6-4=2
There are seven cows in a pasture and five of those cows are red. What
fraction of the cows are red?
Answer:
5/7
Step-by-step explanation:
Since we have 7 cows in total our denominator would be 7 for now. 5 of the cows are red, so 5/7. Since we can't simplify 5/7 that is our final answer.

A researcher decides to split scores on an exam into quartiles. She determines that a score of 64 is at the 25th percentile, a score of 74 is at the 50th percentile, and a score of 80 is at the 75th percentile. What is the interquartile range (IQR) for these data
Answer: IQR = 16
Step-by-step explanation:
The given data is 25 th percentile is 64, 50th percentile is 74 and 75 th percentile is 80.
percentage : 25 50 75
score : 64 74 80
Median:- The median is obtained by first arranging the data in ascending or descending order and applying the following rule.
If the number of observations is odd, then the median is observation
term
If the number of observations is even, then the median is observation and observations.
given n=3, middle term is '74'
In this given data the median is (M) = 74
Interquartile range IQR = median of upper half-median of lower half
= 80-64
= 16
IQR = 16
