20 marbles in all of which: 5 are blue, 5 are red, 5 are white and 5 are black
Drawing 2 marbles without replacing the 1st blue drawn
P(2 blue) = 5/20*4/19 = 20/380 = 1/19
Drawing 2 marbles with replacement of the first blue one
P(2 blue) = 5/20*5/20 = 25/400 = 1//16
1/16 > 1/19
Step-by-step explanation:
the constant is 6..............
If the two supplementary angles are two different lines, and if it's asking for the longer angle, which is 9x....
9x° = 180° ⇒ 20°
Answer:
36x^4y* y^5
Step-by-step explanation:
Given data
Width = 4x^3y ft
Length=9xy^5 ft
We know that the expression for the area is given as
Area= Length*Width
Area= 9xy^5*4x^3y
Area= 36x^4y* y^5
Answer:
0.3557 = 35.57% probability that one selected subcomponent is longer than 118 cm.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean
and standard deviation
, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Normally distributed with a mean of 116 cm and a standard deviation of 5.4 cm.
This means that 
Find the probability that one selected subcomponent is longer than 118 cm.
This is 1 subtracted by the pvalue of Z when X = 118. So



has a pvalue of 0.6443
1 - 0.6443 = 0.3557
0.3557 = 35.57% probability that one selected subcomponent is longer than 118 cm.
