Answer:
6 cups of sugar
Step-by-step explanation:
3/4x2=1.5
1.5x4=6
area / 2 will give you your answer. so if 10.5x12 is 126 then the correct answer is 63
Answer: 0.9984224
Step-by-step explanation:
Let p is the proportion of cell phone owners who used their phone to text.
Given : The probability of cell phone owners who used their cell phone to send or receive text messages was : p= 0.80
sample size : n= 1000
Then, the the probability that
was between 0.76 and 0.84 will be :-
![P(0.76](https://tex.z-dn.net/?f=P%280.76%3Cp%3C0.84%29%3DP%28%5Cdfrac%7B0.76-0.80%7D%7B%5Csqrt%7B%5Cdfrac%7B0.80%280.20%29%7D%7B1000%7D%7D%7D%3C%5Cdfrac%7B%5Chat%7Bp%7D-p%7D%7B%5Csqrt%7B%5Cdfrac%7Bp%281-p%29%7D%7Bn%7D%7D%7D%3C%20%5Cdfrac%7B0.84-0.80%7D%7B%5Csqrt%7B%5Cdfrac%7B0.80%280.20%29%7D%7B1000%7D%7D%7D%20%29%5C%5C%5C%5C%3DP%28-3.16%3Cz%3C%203.16%29%3D1-2P%28z%3E3.16%29%5C%20%5C%20%5B%5Cbecause%20P%28-z%3CZ%3Cz%29%3D1-2P%28Z%3E%7Cz%7C%29%5D%5C%5C%5C%5C%3D1-2%280.0007888%29%3D0.9984224)
Hence, the required probability = 0.9984224
