1 yard=36 inches 1 foot=12 inches and 1/3 yard 1 inch= 1/36 yard and 1/12 foot
Answer:
Step-by-step explanation:
The two x intercepts are
x - 7 = 0
x = 7
x + 3= 0
x = - 3
The y intercept is just - 7 * 3 = - 21
To prove this more formally
f(x) = (x - 7)(x + 3)
f(x) = x^2 - 7x + 3x - 21
f(x) = x^2 - 4x - 21
Answer:
0.57142
Step-by-step explanation:
A normal random variable with mean and standard deviation both equal to 10 degrees Celsius. What is the probability that the temperature at a randomly chosen time will be less than or equal to 59 degrees Fahrenheit?
We are told that the Mean and Standard deviation = 10°C
We convert to Fahrenheit
(10°C × 9/5) + 32 = 50°F
Hence, we solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 59 °F
μ is the population mean = 50 °F
σ is the population standard deviation = 50 °F
z = 59 - 50/50
z = 0.18
Probability value from Z-Table:
P(x ≤59) = 0.57142
The probability that the temperature at a randomly chosen time will be less than or equal to 59 degrees Fahrenheit
is 0.57142
