Answer:
- 3/5
Positive
Step-by-step explanation:
when plotting on a number line, you will start with the first term listed in the equation, in this case it is -3/5
then, if the next term is positive, you will move to the right (aka positive direction), but if the next term is negative then you will move to the left (aka negative direction)
in this question, the next term is positive, so you will move in the positive direction
Answer: 0.965
Step-by-step explanation:
Given : Water use in the summer is normally distributed with


Let X be the random variable that represents the quantity of water required on a particular day.
Z-score : 

Now, the probability that a day requires more water than is stored in city reservoirs is given by:-

We can see that on comparing the above value to the given P(X > 350)= 1 - P(Z < b) , we get the value of b is 0.965.

Answer: x4 + 4x3 + 10x2 is the correct option
Step-by-step explanation:
The standard form a a polynomial depends is written with respect to the highest power to which the variable or unknown of that polynomial is raised. The term which is raised to the highest power always begin the polynomial. This is followed by the other terms whose variables or unknowns has lower are raised to lower powers and it is in a descending order.
Looking at the polynomials given, the only one written in standard form is
x4 + 4x3 + 10x2
The powers of x are arranged in a descending order.
