Answer:
a) 99.97%
b) 65%
Step-by-step explanation:
• 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.
• 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.
• 99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.
Mean of 98.35°F and a standard deviation of 0.64°F.
a. What is the approximate percentage of healthy adults with body temperatures within 3 standard deviations of the mean, or between 96.43°F and 100.27°F?
μ - 3σ
98.35 - 3(0.64)
= 96.43°F
μ + 3σ.
98.35 + 3(0.64)
= 100.27°F
The approximate percentage of healthy adults with body temperatures is 99.97%
b. What is the approximate percentage of healthy adults with body temperatures between 97 .71°F and 98.99°F?
within 1 standard deviation from the mean - that means between μ - σ and μ + σ.
μ - σ
98.35 - (0.64)
= 97.71°F
μ + σ.
98.35 + (0.64)
= 98.99°F
Therefore, the approximate percentage of healthy adults with body temperatures between 97.71°F and 98.99°F is 65%
This is a quadratic equation, which is also a polynomial. Polynomials all have the domain (-infinity, +infinity).
As for the range: You can see from the graph that the smallest y-value is -2. Thus, the range is [-2, infinity).
Answer:
C. 72 sorry if its wrong
Step-by-step explanation:
trapezoid formula : A= 1/2h(B+b)
plug in:
A= 1/2×6(10+14)
A= 3(24)
A= 72
<span>-3(2m-1)-n
First we multiply -3 to the first term of the expression
---------- > ( -3*2m + (-3)*(-1) ) - n
</span>---------- > ( -6m + 3 ) - n<span>
-----------> -6m -n + 3
Then, we divide and multiply by -6, (the expression remains the same)
</span>
---- > (-6/-6)* (-6m -n + 3)<span>
---- > -6*[m + (n/6) - 1/2]
</span>
The answer is -6*[m + (n/6) - 1/2]
75% because each section is 25%, so if you add 25 from each section, you get 75%
