Hey there! I'll only explain you how to solve it and you'll have to find the answer yourself so you learn! <3 Anyhow, To simplify a complex fraction here are the steps.
(1) Convert mixed numbers to improper fractions.
(2) Reduce all fractions when possible.
(3) Find the least common denominator (LCD) of all fractions appearing within the complex fraction.
(4) Multiply both the numerator and the denominator of the complex fraction by the LCD.
(5) When possible reduce, simplify and convert to mixed numbers, any final fraction results.
Hope this helps! <3

Hello there.
Question: <span>The diameter of a circle is 19 inches. Using the formula C ≈ 3d, what is the approximate circumference of the circle?
Answer: The formula is stating that the circumference is approximately equal to 3 times the diameter.
If the diameter is 19 in then to figure out the approximate value of the circumference you need to multiply it by 3.
19 x 3 = 57.
The circumference is approximately 57 in.
Hope This Helps You!
Good Luck Studying ^-^</span>
Using the Empirical Rule, it is found that the standard deviation of the sample is of:
C. 4
By the <em>Empirical Rule</em>, 95% of the measures are within 2 standard deviations of the mean, that is, between 2 standard deviations below the mean and 2 standard deviations above the mean.
95% of people's heights are <u>between 168 and 184 centimeters</u>, hence, there are 4 standard deviations between 168 and 184 centimeters. Then:
![4s = 184 - 168](https://tex.z-dn.net/?f=4s%20%3D%20184%20-%20168)
![4s = 16](https://tex.z-dn.net/?f=4s%20%3D%2016)
![s = \frac{16}{4}](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B16%7D%7B4%7D)
![s = 4](https://tex.z-dn.net/?f=s%20%3D%204)
Hence, option C is correct.

Answer:
a) P(2) = 0.2646
b) P(x > 2) = 0.5334
c) P( 2 <= x < = 5) = 0.7694
Step-by-step explanation:
n = 10
p = 0.27
q = 0.73
x = 10
P(x=0) = (10 C 0 )(0.27^0)(0.73^(10-0)) = 0.043
P(x=1) = (10 C 1 )(0.27^1)(0.73^(10-1)) = 0.159
P(x=2) = 0.2646
P(x=3) = 0.2609
P(x=4) = 0.1689
P(x=5) = 0.075
P(x=6) = 0.0231
P(x=7) = 0.0049
P(x=8) = 0.000677
P(x=9) = 0.0000557
P(x=10) =0.00000206
a) P(2) = 0.2646
b) P(x > 2) = P(3) + P(4) + P(5) + ... + P(10) = 0.5334
c) P( 2 <= x < = 5) = P(2) + P(3) + P(4) + P(5) = 0.7694
