Answer:
x = 1.5
Step-by-step explanation:
Since the axis of symmetry is between the 2 x intercepts, we can find it by finding the average of the x-coordinates of the 2 points.
(-7 + 10) / 2
3/2
= 1.5
So, the axis of symmetry is at x = 1.5
The answer is the 3rd one
Answer:
240
the always the + and the - = +
so positive plus minus equals positive
-2/1 is the slope
-5 is the y intercept
In the spinner there are eight numbers numbered from 1 to 8.
To solve this problem, we must remember that probability is:
Probability = number of successful events / number of total
events
a. P (even number). There are 4 even numbers, therefore the
probability is:
P (even number) = 4 / 8
P (even number) = ½ = 0.5 = 50%
The probability of getting an even number is 50%.
b. P (a number greater than
3). There are 5 numbers greater than 3, therefore the probability is:
P (number greater than 3) = 5
/ 8
P (number greater than 3) = 0.625
= 62.50%
The probability of getting a number greater than 3 is 50%.
c. P (an odd number). Similar
to the even number, there are 4 odd numbers. Therefore,
The probability of getting an odd number is 50%.
