Answer:
= 2.78% probability it will land on both 2 sides.
Step-by-step explanation:
For each trial, there are only two possible outcomes. Either it lands on 2, or it does not. The probability of the spinner landing on two in a trial is independent of any other trial, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
One of the six sides is 2:
This means that
If the spinner is spun two times, what is the probability it will land on both 2 sides?
This is P(X = 2) when n = 2. So
= 2.78% probability it will land on both 2 sides.
Answer:
A: The line will shift vertically up by 125°.
Step-by-step explanation:
So, the experiment starts with the metal at -100° then the start temperature changes to (positive) 25°. All you have to do is calculate how far away -100 is from 25. To calculate this, add 100 (for -100°) and 25 (for 25°) which equals 125. On the chart the line will shift vertically up

Answer:
The equation is:
y= -2x + 3
Step-by-step explanation:
There are two ways to solve this:
You could do very long algebra but you could also just plug in your information and make life easy for yourself.
Start of by plugging in your slope into the equation. (due to y=mx+b, m= slope=-2)
y= -2x + _
Then plug in the co-ordinates give.
(1) = -2(1) + z
Then solve for z
1 = -2 +z
+2 +2
z= 3
Then plug all your information in to get
y= -2x +3
Answer:
224 feet^3
Step-by-step explanation:
Cube -> Volume = 4×7×7 = 196 feet^3
Prism -> Volume = 2×7×2 = 28 feet^3
196+28=224
Answer:
Eric earnings equals $7
Step-by-step explanation:
Let amount earned by Robert = $10
Amount earned by Eric = $x
Robert earnings = 2x - 4
2x - 4 = 10
2x = 10 + 4
2x = 14
Divide both sides by 2
x = 14 / 2
= 7
x = 7
Eric earns $x which is equal to $7
Eric earnings equals $7
