Answer:
y = - 6x - 57
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - 6, thus
y = - 6x + c ← is the partial equation
To find c substitute (- 9, - 3) into the partial equation
- 3 = 54 + c ⇒ c = - 3 - 54 = - 57
y = - 6x - 57 ← equation of line
Answer: No es posible (It is not possible)
Step-by-step explanation:
The question in english is as follows:
Is it possible to draw 9 line segments so that each segment crosses exactly 1 of the other segments?
A necessary condition for two lines to intersect is that they must be in the same plane (they must be coplanar), being their intersection a single point.
Now, if we want several lines to intersect only once, we need to have an <u>even number</u> of line segments. However, this is not the case because <u>9 is odd.
</u>
Therefore, it is not possible.
Answer:
9
Step-by-step explanation:
The first operation is what inside the braces
1-first comes the multiple and the division
2- then the + and the -
1- (25-36)+5(8-4)
2- (25-36) + 5×4
3- (-11) + 20 =9
3x + (x-2) =10
4x-2=10
4x=12
x=3
y=3-2=1
Answer is D
Answer:
So then we will expect 9.98 packages between 2-4 rookie cards in the sample of 10
Step-by-step explanation:
Let X the random variable that represent the number of rookie cards of a population, and for this case we know the distribution for X is given by:
Where 
and 
We select a sample size of n = 10 variety packs and we want to find this probability:
We can use the z score formula given by:
If we apply this formula to our probability we got this:
We can find the z score for 2 and 4 and we got:
So we can find the probability with this difference
And using the normal standard distirbution or excel we got:
So then we will expect 9.98 packages between 2-4 rookie cards in the sample of 10
