Answer: 1.2
Step-by-step explanation:
Let x be a random data value that follows a normal distribution.
The formula to find the z-value :-
, where is the population mean and is the standard deviation.
Given : A data value has a Z-value equal to 1.2.
Then, we have
Hence, the data value is 1.2 standard deviations from the mean.
Answer:
35 cm
Step-by-step explanation:
Perimeter is the sum of all edges of the given figure.
Given: the perimeter of the base of the regular triangular pyramid is P = 16.5 cm and the perimeter of a lateral face is 18.5 cm.
To find: sum of all edges of this pyramid
Solution:
sum of all edges of this pyramid = perimeter of the base of the regular triangular pyramid + perimeter of a lateral face = 16.5 + 18.5 =35 cm
Step-by-step explanation:
slope of line r= (13-4)÷(2-10)
=9/-8
slope of line s = 8/9
D. SSS congruence theorem
Step-by-step explanation:
<u><em>I got SSS since AB and CD are equal and BC and DA are equal plus + the fact that AC=AC shows that it is the SSS congruence theorem</em></u>
