Answer:
For red you have a 1/5% chance for pink you have a 2/4% chance also know as 50% chance
Step-by-step explanation:
Given the total number of students are 180, the mean of data is 88g, and standard deviation is 1g.
A normal curve is a bell-shaped curve with symmetry about the mean and it spreads uniformly on both sides (left side and right side) of the mean.
The empirical rule is also called "68-95-99.7" rule. It says that :-
A) 68% of the data values fall between 1 standard deviation about mean (34% on left side and 34% on right side),
B) 95% of the data values fall between 2 standard deviations about mean (47.5% on left side and 47.5% on right side), and
C) 99.7% of the data values fall between 3 standard deviations about mean (49.85% on left side and 49.85% on right side).
According to distribution of normal curve and "68-95-99.7" empirical rule, we can say 49.85% of data values are above the mean within 3 standard deviations.
So it means 49.85% of total students report readings more than 88g.
Number of students reporting readings more than 88g = 49.85% of 180 = 0.4985 × 180 = 89.73
Hence, approximately 89 students report readings more than mean value.
Answer:
15/4.
Step-by-step explanation:
4th term = a1 r^3
= 30(1/2)^3
= 30/8
= 15/4.
5- 12 centimeters is equal to 0.12 m:
the last one is true
6-
the second one is true
Answer:
Step-by-step explanation:
take angle U as reference angle
using sine rule
sin U=opposite /hypotenuse
sin U=42/42
sin U=1
sin 90=1
therefore angle U=90 degree
