Step-by-step explanation:
2.7 + 3.5 is not greater than 9.8.
Answer:
Helene is right
Step-by-step explanation:
Mathematically, the expected values is defined as the sum of all the possible outcomes that an event can have times the probality of the respective outcome:
x = ∑ p *i,
where x is the expected value, i represents every outcome that can occur, and p is the probability of said outcome.
Now, for the case of a dice, the expected value would be:
x = 1 *
+ 2 *
+ 3 *
+ 4 *
+ 5*
+ 6 *
,
as every outcome has the same chance of happenning. Solving we get that:
x=
*(1 +2 +3 +4+5+6) =
* 21 = 3.5
Helene is right.
Using the picture:
Between (-3, -4) and (5, -4) is:
The difference is in the x units: 5 - (-3) = 5 + 3 = 8
Between (5, 2) and (5, -4) is:
The difference is in the y units: 2 - (-4) = 2 + 4 = 6
We know the shape is a right angled triangle:
By applying Pythagoras' Theorem:
let the hypotenuse be x:
x² = 6² + 8²
x² = 36 + 64
x² = 100
Take square root of both sides
√x² = √100
x = 10
Distance between the 2 points = 10 units.
Option D.
Answer: 24
Step-by-step explanation:
<u>Evaluate (y+z)2 when y=−3 and z=15.</u>
(-3 + 15)*2 = 12 * 2 = 24
