Answer:
Option A. a loss of 93.98 points
Step-by-step explanation:
To solve this question we will calculate the difference (change)in closing amount of Dow Jones on stock market that took place on day to day basis.
From 01/27 to 01/28
Change = 13881.93 - 13895.98 = (-14.05)
From 01/28 to 01/29
Change = 13954.40 - 13881.93 = (+72.42)
From 01/29 to 01/30
Change = 13860.42 - 13954.40 = (-93.98)
Here we can see that change from 01/29 to 01/30 is maximum and it is (-93.98).
Therefore answer will be Option A. a loss of 93.98 points.
To isolate b, add a and subtract c to the entire equation:
D - a + c = -b
Muliply b by -1 to eliminate the negative:
-D + a - c = b
Probability would been equal to 0.9841 if we randomly select 20 bottles it fills.
<h3>What is Probability ?</h3>
The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of the positive results for the experiment with 'n' outcomes can also be represented by the symbol x. The probability of an event can be calculated using the following formula.
Probability(Event) = Positive Results/Total Results = x/n
Given,
n = 20
p = 0.05
Thia information gives information about binomial distribution with parameter n = 20 , p = 0.05
Let X be the number of bottles have caps that she not properly applied
X∝ B( n=20 , p= 0.05)
The p.m.f of X is
P( X=0)= (
) ( 0.05)ˣ (1 - 0.05)²⁰ ⁻ˣ
; x = 0 , 1, 2.......20
0 < p < 1
q= 1 - p
= 0 ; otherwise
P {x ≤ 3} = P { X = 0 } + P{ x= 1 } + P { x= 2 } + P { x= 3}
P( X=0)= (
) ( 0.05)⁰ (1 - 0.05)²⁰ ⁻⁰ = 0.3585
P( X = 1)= 0.3774
P( X= 2) = 0.1887
P( X= 3) = 0.0596
= 0.3585+ 0.3774 + 0.1887+ 0.0596
= 0.9841

Answer: No
Step-by-step explanation:

its exponents are;
a=1
b=2
-------------------------------------------

its exponents are;
a=2
b=1
------------------------------------------
For them to be like terms, a = 1 and b = 2 or viceversa in both of them.
