Answer:
that is true
Step-by-step explanation:
i think it's help
Answer:
1/3 = 0.3333 = 33.33% experimental probability of rolling a 9.
Step-by-step explanation:
The experimental probability is given by the number of desired outcomes divided by the number of total outcomes, after a number of experiments is made.
In this question:
Cube rolled 78 times.
9 appeared 26 times
26/78 = 1/3 = 0.3333 = 33.33% experimental probability of rolling a 9.
Problem One
This is a right angle triangle. If it is not, then there is no way to do the problem. the right angle is across from the 19.
Formula
a^2 + b^2 = c^2
Givens
a = 17
c = 19
Sub and solve
17^2 + b^2 = 19^2
289 + b^2 = 361 Subtract 289 from both sides.
b^2 = 361 - 289
b^2 = 72 Take the square root of both sides.
b = sqrt(72) Factor 72
b = sqrt(6 * 6 * 2) Take 6 outside the root sign.
b = 6*sqrt(2)
This is one possible answer b = 6*sqrt(2)
The other is a decimal b = 6 * 1.414 = 8.485
Problem 2
Remark
If you are just counting units then the answer is 11 (miles). If you want an answer that goes the way a bird would fly directly to it then the problem will look like this.
Givens
Points (4,3) and (10,8)
Formula
d = sqrt( (y2 - y1)^2 + (x2 - x1)^2 )
y2 = 8
y1 = 3
x2 = 10
x1 = 4
Sub and solve
d = sqrt( (8 - 3)^2 + (10 - 4)^2 )
d = sqrt( 5^2 + 6^2)
d = sqrt(25 + 36)
d = sqrt(61) Answer
That's one answer
The other is the d = 7.8102 If you have choices show them please.

We are asked to find how many terms are in .
- A term is a thing that's added or subtracted.
So let's compute the number of terms in this expression.
The first term is .
Is anything added or subtracted from 10y²?
Sure! is subtracted from 10y².
Also, 8 is added to -3y.
Thus, this expression has 3 terms.
Hope it helps you out! :D
