If you would like to find the matching equation, you can do this using the following steps:
ax^2 + bx + c = 0
a = -2
b = 1
c = 3
-2x^2 + x + 3 = 0
The correct result would be a. 0 = <span>-2x^2 + x + 3.</span>
Answer:

The way I learned multiplication was with some sayings. "7 times 7 went out to dine, when they came back it was 49"
Answer:
D
Step-by-step explanation:
u can use Pythagorean theorem a2 + b2 =c2. c2 is the length of the hypotenuse. plug in 3 for a and 15 for b. 3 squared plus 15 squared equals c squared. 9+225= c2. 234=c2. answer is D. the square root of 234
Please consider the graph.
We have been given that graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic. We are asked to choose the weights, which are within 2 standard deviations of the mean.
We can see from our graph that mean of the weights is 9.5 and standard deviation in 0.5.
The data point that would be below two standard deviation is:
that is
.
The data point that would be above two standard deviation is:
that is
.
Now we need to check the data points that lie within 8.5 and 10.5.
Upon looking at our given choices, we can see that 8.9, 9.5 and 10.4 pounds lie within 2 standard deviation of the mean.
Therefore, 8.9 lbs, 9.5 lbs and 10.4 lbs are correct choices.
