- Zeros of a Quadratic Function
- Reading a Cartesian Graph
Step-by-step explanation:
We are looking for the zeros of f(x). The blue quadratic is the graph of f(x). Zeros mean the coordinates when the graph crosses the x-axis. Therefore, our correct answer is the last choice.
Answer:
If it is multiple answers then it would be the last one or the second one. If not, I would just choose the 2nd one
Step-by-step explanation:
If you meant integer, then the correct answer is 1,395. An integer is a whole number, which means that the first integer place is the ones place. Since the number is 1,395, it is a whole number, so the digit in the tenths place, to the right of the ones place, is 0. Since 0 is less than one, we keep the ones place the same, so 1,395 remains 1,395.
Hope this helps!
The distance covered by the hiker if he traveled a horizontal distance of 120 ft at and angle of 6° will be given by:
cos θ=adjacent/hypotenuse
let the hypotenuse be h, adjacent =120 ft, θ=6°, thus plugging in the values we shall have:
cos 6=120/h
h=120/cos 6
h=120.661 ft
Answer: 120.661 ft
Answer:
Normal distribution table
Step-by-step explanation:
We need to define all the variables that are presented to us in the problem, like this:
Data point in question = xi = 36000
The mean = μ = 32000
The standar variation = s = 3000
calculate the z-score for the left bound
x = 36000:
where μ = 32000, s = 3000, n = 1. (There is only one
teacher in the sample.)
z-score for 36000 is calculated thusly:
It is necessary to look in the normalized table for this value, and look in the area on the left that for 1.33 the result is 0.9082
<em>So our probability is 0.9082 that he or she makes more than $36000</em>
