Answer:
third choice : Let 2a + 1 be one odd number, and let 2b + 1 be the other odd number. (2a + 1) + (2b + 1) = 2a + 2b + 2 = 2(a + b + 1). Because 2(a + b + 1) is evenly divisible by 2, it is an even number.
You’re welcome ;)
Answer:
you would add 6 ounces of water to 9 ounces of mix
Step-by-step explanation:
to find the ratio of water to pancake mix, divide 4/4 and 6/4 to find the unit ratio of water to each 1 ounce of mix.
6/4 = 0.66...
0.66... ounces of water is used per 1 ounce of mix.
0.66... * 9 = 6
this means that 9 ounces of mix would use 6 ounces of water.
Answer:
I think the answer would be $466.24.
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
It's a vertical line, parallel to the y-axis, crossing the x-axis at the point x=22.
No matter what number you choose for 'y', you'll always find that x=22 there.
