X^2+y^2=z^2
x^2+96^2=100^2
x=sqrt(100^2-96^2)
x=28 so the distance from the base of the ladder and the base of the ladder is 28ft.
Hope this helps. Any questions please just ask. Thank you.
Answer:
A statistic is said to be unbiased if the mean of its sampling distribution is equal to the true value of the parameter being estimated.
Step-by-step explanation:
A parameter is a number that describes the population.
A statistic is a number that describes a sample.
A statistic used to estimate a parameter is unbiased if the mean of its sampling distribution is exactly equal to the true value of the parameter being estimated. For example, the mean of a sample is an unbiased estimate of the mean of the population from which the sample was drawn.
A statistic is biased if its expected value is not equal to the parameter.
A)y-intercept = 8 slope = up 4 right 4
b)y-intercept = -2 slope = down 2 right 3
Answer:
Step-by-step explanation:
<u>Factor x³ + 2x:</u>
1. <u>The common factor is x, then</u>:
- 2 + k = 0 ⇒ k = -2 (all the rest are divisible by x)
2. Factor x² + 2 is not linear therefore we discard it.
