Answer:
2
Step-by-step explanation:
y = 0 at the point where the function intersects x-axis. Thus, yiou have to put
2x2 + x - 10 = 0
and solve the equation. It is better to factor the quadratic expression, which gives us
2x2 + x - 10 = (2x+5)(x-2) = 0
We have 2x +5 = 0 and x-2 = 0. Thus, the intercepts are x = -5/2 = - 2.5 and x = 2.

The average IQ test score would be 100.
What is a normal distribution?
A probability distribution that is symmetric about the mean or average is the normal distribution, sometimes referred to as the Gaussian distribution. It demonstrates that data that are close to the average value occur more frequently than data that are far from the mean. The normal distribution appears as a "bell curve" on a graph.
Average IQ Score
A score of 100 is regarded as the average IQ on various tests. The majority of results (68%) are within one standard deviation of the mean (that is, between 85 and 115). This indicates that the average result is within plus or minus 15 points for almost 70% of test takers.

Answer:
15 units = h
Step-by-step explanation:
formula to find the volume is:
V = (l·w·h) ÷ 3
675 = (9)(15)h ÷ 3
675 = 135h ÷ 3
multiply each side by 3 to get:
2025 = 135h
2025/135 = h
15 = h
First of all, the angle bisector, angle ray and angle line are all lines. Please refer to the picture attached. All of these lines are joined at one point called vertex which is at point O. The angle bisector is the line that divides the total angle into half. In this case, that would be line OB. The angle ray and line are the two legs of the angle, which are line OA and line OC, respectively.
