Answer:
The probability of getting exactly two tails = 1/4
All the values greater than 1/4
or 3/4
Step-by-step explanation:
In a flip of a coin the probability of getting a tail is 1/2. If this is denoted by p =1/2 then q= 1-p= 1-1/2= 1/2
and if we have number of trials n=2
Then the binomial distribution can be applied.
(p+q)ⁿ =(p+q)² = 2c0p⁰q2 + 2c1p¹q¹ + 2c2p²q⁰
We wish to find probability of flipping exactly two coins given by 2c2p²q⁰
= 2c2 (1/2)²(1/2)⁰
= 1/4
So the probability of getting exactly two tails = 1/4
The probability greater than 1/4 can be all the values from 2/4, 3/4 ------1
or it can be found by
1- 1/4 = 3/4
as the total probability is always equal to 1
A circle with a radius of 4 inches has a diameter that is 3x+5 inches long. What is the value of x?
Answer:
x=1
Step-by-step explanation:
The radius of a circle is half of the diameter.
Because we know this, we can multiply the radius by 2 to equal the diameter:
4*2=3x+5
Then we solve for x:
8=3x+5
3=3x
x=1

A local ice cream shop wants to see if they should promote a new swizzleberry swirl or creamsicle flavored drink. In order to determine which one to promote, they took a sample of 80 patrons and asked them to choose which they preferred. The one that is significantly preferred over the other (at a .05 level of significance) will be promoted. It is expected that an equal number of patrons will choose each flavor. Based on the observed frequencies given below, what is the decision for this test
A soda can is made out of aluminum. It is 12
centimeters tall and has a diameter of 7.5
centimeters. How many cubic units of soda
would be needed to fill the can?
(Use 3.14 as PI)
Answer:
529.875 [tex]cm^3[/tex]
I don't know if they want it rounded or not, but rounded it would be 529.88 or 529.9
Step-by-step explanation:
Find the volume of the can (cylinder):
h = 12 cm
d = 7.5 cm
r = 1/2d = 3.75 cm
[tex]V=\pi r^2h\\\\= (3.14)(3.75)^2(12)\\\\= 529.875[/tex]

Hello, can you please help me solve for the y intercept?
Answer:
The y-intercept is when the X is 0 And the y is whatever number it is. So in order to do that we need to find the pattern first and to do that we need to find the slope.
The slope here is 2/ 2 or 1.
So you add 1 to each side to find the next ordered pairs.
-5, -7
-4, -6
-3, -5
-2, -4
-1, -3
0, -2
So the y-intercept is -2.
