Answer:
Slope intercept form: y= -x-2
Slope: -1
Y-intercept: -2
Step-by-step explanation:
To find slope, use the equation:
(y₂ - y₁)/(x₂ - x₁) = slope
Let:
(8,8) = (x₂, y₂)
(5,5) = (x₁, y₁)
Plug numbers into corresponding areas.
(8 - 5)/(8-5) = 3/3
3/3 = 1
The slope of the line is 1, or 1/1 (rise 1, run 1)
hope this helps
Probabilities are used to determine the chances of an event
The probability of event B is 0.62
The probabilities are given as:
To calculate the probability of event B, we make use of the following formula
So, we have:
Collect like terms
Hence, the probability of event B is 0.62

Answer:The value of the z-score tells you how many standard deviations you are away from the mean. ... A positive z-score indicates the raw score is higher than the mean average. For example, if a z-score is equal to +1, it is 1 standard deviation above the mean. A negative z-score reveals the raw score is below the mean average.

Answer:
149 inches squared
Step-by-step explanation:
top rectangle: 25 * 7 = 175
second rectangle: 8 * (25 - 17) = 8^2 = 64
triangle in bottom right: 1/2 * (13 - 8) * (15 - 11) = 10
175 + 64 + 10 = 149 sq in
hopefully got this right!
