Answer: 9.73 lb each chair
Step-by-step explanation:
You substract the weight of the table alone from the full weight:
235.68 - 157.84=77.84
Then you divide 77.84 by 8 chairs and you obtain the weight of each individual chair
77.84/8= 9.73 the weight of each individual chair
Answer:
D
Step-by-step explanation:
D is the only graph where the shaded region is on 6 and less.
The 25th percentile corresponds to z ≈ -0.67.
The 90th percentile corresponds to z ≈ 1.28.
So, you can write two equations in μ and σ as here:
.. μ -0.67σ = 10
.. μ +1.28σ = 20
The solution is
.. μ ≈ 13.45
.. σ ≈ 5.11
