Answer: No it's less than 1/2. 4/8 would be equal to 1/2
Step-by-step explanation:
That'd be y = 70* (1-.00043)^t, where the rate of decrease is really 0.43% and t denotes the # of weeks.
This simplifies to y = 70*(0.00057)^t.
Notice how 1/2 and 3/8 are positive numbers. We add two positive numbers meaning that the result should be larger. However 2/5 = 0.4 is not larger than 1/2 = 0.5
So something went wrong with the adding. It turns out that the error is when the person added the numbers in the denominators (2 and 8 to get 10). This is not allowed. The denominators must be the same and stay the same in order for the fractions to be added.
For example: 1/7 + 2/7 = (1+2)/7 = 3/7
The 7s in the denominator do not change
Therefore the answer is choice B) Not true because 2/5 < 1/2
Expand (x - 5)^2
(x - 5)^2 = (x - 5)(x - 5)
Multiply all the terms in the first parenthesis to all the terms in the 2nd:
x * x = x^2
x * -5 = -5x
-5 * x = -5x
-5 * -5 = 25
So we have:
x^2 - 5x - 5x + 25
Combine like terms:
x^2 - 10x + 25
Plug it back in:
y = (x - 5)^2 - 2
y = x^2 - 10x + 25 - 2
Combine like terms:
y = x^2 - 10x + 23
Answer:
A. The data are continuous because the data can take on any value in an interval.
Step-by-step explanation:
A continuous data is any data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous data.
Hence, the exact heights of different elephants represents a continuous data because the data can take on any value in an interval.
On the other hand, a discrete data is any data set in which the number of possible values are either finite or countable. Thus, a discrete data can only take on specific values. For example, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
