Answer:
The first graph. (an upside down U)
Step-by-step explanation:
The leading coefficient of a polynomial determines the direction of the graph's end behavior.
A positive leading coefficient has the end behavior point up when an even degree and point opposite directions when an odd degree with the left down and the right up.
A negative leading coefficient has the end behavior point down when an even degree and point opposite directions when an odd degree with the left up and the right down.
This graph has two evens. Because its negative, only one is possible - the first graph.
The other two graphs are odd with both starting down on the left and point up on the right which is a positive leading coefficient. These are not possible graphs.
The first graph is the solution.
In math, prime factorization is defined as the <span>finding of the </span>prime<span> numbers that multiply together to make a particular number. A prime number is a number that is only divisible by itself and one. In this case, the correct prime factorization of 28/98 is </span><span>(2x2x7)/(2x7x7), and when you reduce the fraction to its lowest term, you will get 2/7. Hope this answer helps.</span>
Answer: the slope of this line is 2/3
Step-by-step explanation:
If you use rise/run, you will find that rise=2 and run=3, so the slope 2/3.
Answer:
0.3745
Step-by-step explanation:
Data
mean (
): 80
standard deviation (
): 4
Normal distribution table is in figure attached
.
Z = (85 - 80)/4 = 1.25
Area below curve = 0.3944
Z = (82 - 80)/4 = 0.5
Area below curve = 0.0199
Proportion of exam scores between 82 and 85?
0.3944 - 0.0199 = 0.3745
Answer:
144
