Answer: Choice A

Ahmed started 6 floors above ground level, then he went down 8 floors

The +6 or simply 6, is positive, so he's on the 6th floor to start. Then adding on -8, which is the same as subtracting 8, moves him down 8 floors.

6 + (-8) = 6 - 8 = -2 indicates he's 2 floors below ground level, so he's in basement level 2 (perhaps some kind of parking garage).

PLZZ HELP!! WILL MARK BRAINLIEST PLZZ!!!
grandymaker [24]

Answer:

see below

Step-by-step explanation:  7  1  16   33

  y  = x²   translated t the point (3, 2)         y = 0 when x = 0

  y =  (x - 3)²    moves the function three units to the right     y = 0 when x = -3

  y  = (x-3)² + 2  moves the function up 2 units      y = 2 when x = -3

  y = (x-3)² + 2

  y = x² - 6x + 9 + 2

  y = x² - 6x +11

graph the equations x²,  (x-3)² + 2,  and x² - 6x + 11   to verify (I did)

As part of his semester project, a BYU-Idaho Introductory Statistics student calculates a 95% confidence interval for the true p
lyudmila [28]

Answer:

a. There's a 95% chance that the true proportion is in the confidence interval.

Step-by-step explanation:

When we want to estimate a property of a population (a population's parameter), without surveying the population, we use samples.

Then, with the information of the samples we can calculate the statistics and infere properties about a population. This inferences obviously came with some uncertainty, depending on the properties of the sample and specially the sample size.

When we talk about confidence intervals, we use the statistic of the sample (in this case, the mean) to estimate a range of values it is expected to find the true mean of the population. The width of this interval depends on the sample standard deviation and the sample size.

The value of the confidence interval (95%, 99%, etc) represent the probabilty that the true mean is within this interval.
