Answer:
The population mean (μ) = 26.
Step-by-step explanation:
a) Data and Calculations:
The population characteristics = 20 and 36
Total population of interest = 56 (20 + 36)
Number of groups in the population = 2
Therefore, the population mean (μ) = 56/2 = 28
b) Based on the parameters given in this example, the population mean equals the average of the group characteristic (attention span of individuals in minutes) or item of interest. The population mean is calculated by adding the values of the group characteristic and then dividing the result by the number of values.
Answer:
y=\sqrt{x+2}
Step-by-step explanation:
we know that
In this problem the rule of the transformation is
(x,y)-------> (x-2,y)
That means
The transformation is a translation 2 units to the left
therefore
\sqrt{x} --------> \sqrt{x+2}
the answer is
y=\sqrt{x+2}
1+ w2= d12
d12 + h2 = d22
(12+ w3) + h2 = d22
62+22+42=022
48=022
d2 = 148
d2 = V(16)(3)
d2 = 4v3
Use the Pythagorean theorem twice 1 time to find the diagonal one the bottom from the box. And then find the 2 diagonal using the one before which is diagonal 1 and find the height of the box. Hope this helps!
Answer:
x =
Step-by-step explanation:
Well first you have to isolate x so divide by 3/4 on both sides. when you divide a fraction by another fraction you multiply by the reciprical.(I think i spelled reciprical wrong, tell me if i did) Therefore you must multiply
1/7 by 4/3 giving you 4/21 which is equal to x.
