Answer:
17.3 cigarettes represent the 35th percentile
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What number of cigarettes would represent the 35th percentile?
This is the value of X when Z has a pvalue of 0.35. So it is X when Z = -0.385.
So
17.3 cigarettes represent the 35th percentile
Answer:
Solution,
x+12+8x-2=180° (Linear pair)
or, 9x+10=180°
or, x+10=180/9
or, x=20-10
x=10
The length of MT
=8x-2
=8×10-2
=80-2
=78

Answer:
26.13 ft²
Step-by-step explanation:
The total area is twice the area of the right triangles plus half the area of a circle of radius 3 ft.
Semicircle area = (1/2)(πr²)
semicircle area = (1/2)(3.14)(3 ft)² = 14.13 ft²
The area of the two right triangles is ...
total triangular area = (3 ft)(4 ft) = 12 ft²
Then the area of the figure is ...
figure area = semicircle area + total triangular area
= 14.13 ft² + 12 ft² = 26.13 ft²
4 x 4 x 4 x 4 x 4
I think that’s the answer
B. 5
the minimum is where the end of the left tail is. the first quartile is where the beginning of the box is, the mid is in the middle of the box, the 3rd quartile is at the end of the box and the maximum is the end of the right tail.
