Answer:
So we can simplify this to
36+4x=-1
We can subtract by 64 on both sides. 4x = -37. Therefore the answer to this is
x = -37/4 = -9.25.
So the answer for x is -16.25. If you were trying to do a quadratic equation then sorry because you worded it wrong, and I solved properly.

Answer:

Step-by-step explanation:
The speed of the Elvira is 6.545 miles per hour. Then the speed of the Altheia will be 0.545 miles per hour.
<h3>What is speed?</h3>
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
Let the speed of the Elvira be x. Then the speed of the Altheia will be (x - 6).
Let the distance between the coffee shop and Elvira's house be d.
Then the distance between the coffee shop and Altheia's house will be (3.6 - d).
Then we have
x = d / 0.5 ...1
(x - 6) = (3.6 - d) / 0.6 ...2
In solving the equations 1 and 2, we have
x = 6.545 and d = 3.2725 miles
Then the speed of the Elvira is 6.545 miles per hour. Then the speed of the Altheia will be 0.545 miles per hour.

Answer:
Step-by-step explanation:
We are given the following in the question:
x: −4 −3 −2 −1 0
P(X=x): 0.2 0.3 0.1 0.2 0.2
We have to evaluate
Since it is a discrete probability distribution as
We can evaluate the probability as:
Thus, 0.4 is the require probability.
