Answer:
The answer is stratified.
Step-by-step explanation:
The probability is 0.9671.
The z-score for this is given by
z = (x - μ)/(σ/√n)
z = (38000-37500)/(1561/(√33)) = 1.84.
Using a z-table (http://www.z-table.com) we see that the area under the curve to the left of, less than, this is 0.9671.
It’s D, y = 4.
have a good day :)
Answer:
Step-by-step explanation:
so i cant actually see the picture on my school chromebook, but if only one x matches up to one y, then yes. multiple x's can go to a single y
Pretty simple, really - all you have to do us divide 509 by 14 before you're left with an answer of <span>36.35. Now, the number '36' is closer to 0 than 100, so we'll round down instead of up, therefore the number of floors to the building is 36! </span>
