Of the 12 available months, 
of them end in the letter "r" (Sep, Oct, Nov, Dec). The sample space consists of all 12 possible choices of 1 month, but the only outcome we care about is any 1 of these 4 being selected. The probability of choosing any one of these is 
. How you describe the probability is up to interpretation, but probably a good convention to use is to say that an event is "unlikely" to happen if that event has a probability less than 0.5 of occurring.
Answer:
Percentage of heads = 42 %
Net loss = $16
Step-by-step explanation:
Given:
Total number of tosses = 100
Number of heads come = 42
Number of tails come = 58
Find:
Percentage of heads
Net loss
Computation:
Percentage of heads = Number of heads come / Total number of tosses
Percentage of heads = 42 / 100
Percentage of heads = 42 %
Net loss = 58(1) - 42(1)
Net loss = $16
The formula for Circumference is C= πd (with C being Circumference and D being diameter). You would substitute the information into the equation, to find the diameter. After, finding the diameter divide it by 2 to find the radius. When you find the value of the radius, substitute it into the equation (v=4/3πr^3). Volume equals 4 divided by 3, times pi, times the radius cubes (to the power of 3).
Answer:
x = 58°
Step-by-step explanation:
Fact 1) Recall the fact that angles in a triangle add to 180°
Fact 2) Recall the fact that angles on a straight line add to 180°
The first angle we can work out is BAC using fact 2
114 + ? = 180
? = ( 180 - 114 )
? = 66
∠ BAC = 66
Now that we have angle BAC we can utilise the fact angles in a triangle add to 180°, so we can set this equation up
x + 66° + 56° = 180°
x + 122° = 180°
x = ( 180 - 122 )
x = 58°
Answer:
4√10
Step-by-step explanation:
√(8) √(20)
= √(8 x 20)
= √(160)
= √(16 x 10)
= √(16) x √(10)
= 4 x √10
= 4√10
