The 68 - 95 - 99.7 rule, gives the basis to solve this question.
It says that for a normal distribution 95% of the results are between the mean minus 2 standard deviations and the mean plus 2 standard deviations.
Here:
mean = 64.5 inches,
standard deviaton = 2.5 inches
mean - 2 standard deviations = 64.5 inches - 5 inches = 59.5 inches
mean + 2 standard deviations = 64.5 inches + 5 inches = 69.5 inches
Then, the answer is that 95% of women range approximately between 59.5 inches and 69.5 inches.
Answer:
31
Step-by-step explanation:
50 x .62= 31
(games played) x the percentage won.
You could muliply 50 by 62% if your calculator has the % symbol if not you have to turn it into a decimal. To go from percent to decimal just take your percentage and move the decimal to the left twice. 62% = .62
√(1/121) = √1 / √121 = 1 / 11 = <em>11⁻¹</em>

(3t^2 + 2 + (-2)) + (t^2 + 3t - 4) - (4 + (-5))
Apply the distributive property to remove parentheses.
3t^2 + 2 - 2 + t^2 + 3t - 4 - 4 + 5
Combine like terms.
<h3>4t^2 + 3t - 3 is the simplified form of the given expression.</h3>
