Answer:
X is a binomial random variable
Then the condition is met
Step-by-step explanation:
Sample size n₁ = 400
X represents the number of brand-name lightbulbs)
P(X) = 44/400
P(X) = 0,11
X is a binomial random variable it only could be either no defective or defective ( only two conditions or values).
To make use of the condition of approximation of binomial distribution to a normal distribution it is required that the products:
p*n = 0,11*400 = 44 and q = 1 - 0,11 q = 0,89
q*n = 0,89 * 400 = 356
both p*n q*n are greater than 5.
Then the condition is met
Answer:
BC=54, DE=27
Step-by-step explanation:
(7x-1)2=16x-10
x=4
7(4)-1=27
16(4)-10=54
Answer:
d = 8
Step-by-step explanation:
For:
(X1, Y1) = (-4, 5)
(X2, Y2) = (-12, 5)
Distance Equation Solution:
d=(−12−(−4))2+(5−5)2−−−−−−−−−−−−−−−−−−−−√
d=(−8)2+(0)2−−−−−−−−−−√
d=64+0−−−−−√
d=6–√4
d=8
Therefore, the distance between (-4,5), (-12,5) is 8.
It would be every 10 miles. Take the 8 uber charges and add the .75 x 10 giving you 15.50
uber 8 + (.75 x 10) = 8 + 7.50 = 15.50
Do the same with the taxi cost. 3 + (1.25 x 10) = 3 + 12.50 = 15.50
Answer:
-1
Step-by-step explanation:
-b+10b+2b+17=6
9b+2b+17=6
11b+17=6
11b=6-17
11b=-11
b=-1
