Answer:
<h2>u = 9.7</h2>
Step-by-step explanation:
![Opposite =u\\Hypotenuse = 12\\Adjacent = 7\\Using\: Pythagoras \: Theorem\\Hypotenuse^2 = Opposite^2+Adjacent^2\\12^2= u^2+7^2\\144=u^2 +49\\144-49=u^2\\95=u^2\\\sqrt{95} =\sqrt{u^2} \\u = 9.74\\\\u = 9.7](https://tex.z-dn.net/?f=Opposite%20%3Du%5C%5CHypotenuse%20%3D%2012%5C%5CAdjacent%20%3D%207%5C%5CUsing%5C%3A%20Pythagoras%20%5C%3A%20Theorem%5C%5CHypotenuse%5E2%20%3D%20Opposite%5E2%2BAdjacent%5E2%5C%5C12%5E2%3D%20u%5E2%2B7%5E2%5C%5C144%3Du%5E2%20%2B49%5C%5C144-49%3Du%5E2%5C%5C95%3Du%5E2%5C%5C%5Csqrt%7B95%7D%20%3D%5Csqrt%7Bu%5E2%7D%20%5C%5Cu%20%3D%209.74%5C%5C%5C%5Cu%20%3D%209.7)
Answer: If P(x<a) = 0.6, then the value of a will be 0.25.
In this type of problem, it is safe to assume the normal distribution unless you are told something different.
In this probability, we have to find the z-score for a that gives a probability of 0.6. You will need a normal distribution chart to do this problem. Just find the probability that is closest to 0.6 and use that z-score.
4 quarts is equal to a single liter
Answer:
Step-by-step explanation:
Scott has 144 pieces of candy
25% is one 4th
144/4=36
he gives to his sister 36
the answer is b because the piggy bank originally contained $25 and the person adds $1.50 per day.. so: 25+1.5d
