Answer:
about 254.40
Step-by-step explanation:
Put the value where x is and do the arithmetic. (Any scientific or graphing calculator can do this for you.)
f(6) = 325(0.96^6) ≈ 254.40
Answer:
52 miles per hour
Step-by-step explanation:
The speed of the car can be found by dividing the distance by the time. THe distance is 117 miles and the time is 2 1/4 hours or 2.25 hours.
Answer:
The data in statistics is generally supposed to deviate or vary from the mean. Standard deviations of 1, 2, and 3 are commonly used to calculate variability according to the empirical norm. In a normal distribution, we estimate 68 percent, 95 percent, and 98 percent of the data to be within 1, 2, and 3 standard deviations of the mean, respectively. This implies that the given percentage of data will lie within an interval of less than or greater than the standard deviation. If the values within a given standard deviation from the mean are standardized, the z value will always be equal to or less than the given standard deviation.
We should look at a program that aims to help people get out of poverty by using the standard deviation principle. The aim of the program is to provide free seeds to poor people who have been suffering from low yields due to the use of local seeds. If we use the definition of one standard deviation of the mean, or 2 and 3, we will favor the majority of people, but we will leave the poorest people in society behind.
Let's use PEMDAS for this expression (parentheses, exponent, multiplication/division, addition/subtraction) Even though subtraction is first, you would multiply first because multiplication is before subtraction So multiply -(1/4) and (4/9) and you get -(1/9). Now add (2/3) and you get a final answer of (5/9)
