Answer:
Yes
Step-by-step explanation:
Just trust
5.75a + 6.5c = 53.25
a + c = 9
c = 9 - a
5.75a + 58.5 - 6.5a = 53.25
5.25 = 0.75a
a = 7
7 + c = 9
c = 2

Answer:
3/2
Step-by-step explanation:
In order to find the slope with two points, you use this formula:
y2-y1 / x2 - x1.
y2 is 5 and y1 is -4. 5 - -4 = 9
x2 is 2 and x1 is -4. 2 - - 4 = 6
9/6 = 3/2.

Answer:
Step-by-step explanation:
Given that the weights for a population of North American raccoons have a bell-shaped frequency curve with a mean of about 12 pounds and a standard deviation of about 2.5 pounds
Since bell shaped is given we can assume that this follows a normal distribution symmetrical about the mean.
To find 95% two values we can use Z critical value for 95%
i.e. ±1.96
95% will lie between 12±1.96(2.5)
= 12±4.9
=(7.1, 16.9)
