Y=-1/20(x+3)^2
Your could always tell by which way the curve is pointing and if pointing down it’s a negative it’s pointing up it’s a positive
Hope that helped
Answer:
x >= 0 & y<0
x >= 0 means that x is non-negative
y<0 means that y is negative
Answer:
.3
Step-by-step explanation:
The probability distribution in the second row simply shows the probabilities for each number in the first row.
To find the probability that x is between -5 and 5, you can add the probabilities -5 < x < 5.
P(-5) = 0.15
P(0) = 0.05
P(5) = 0.1
0.15 + 0.05 + 0.1 = 0.3
Answer:
In ∆ABC, AD is perpendicular while BC and BE are perpendicular to AC.
Step-by-step explanation:
Answer:
a) Median: 9
b) Range: 5
c) Mode: 7
Explanation:
The median is the number in the middle.
First, you put the numbers in order: 7, 7, 7, 8, 10, 11, 12, 12
The middle of this is 8 and 10, so you plus them and divide by to 2, then it gives 9, so the median is 9.
To find the range, you minus the highest number and the lowest number, 12-7=5.
Mode is the most occurring and repetitive number, in this case, 7, because it is written 3 times.
