Answer:
the single decimal multiplier is 0.7826
Step-by-step explanation:
The computation of the single decimal multiplier is given below:
Given that
It is reduced by 14% that followed by 9% decrease
So according to this, the following calculation is required
= (1 - 0.14) × (1 - 0.09)
= 0.86 × 0.91
= 0.7826
Hence, the single decimal multiplier is 0.7826
First, find the mean. You'll need it to compute the variance.
The variance of the sample is then computed with the formula
The standard deviation is the square root of the variance, so
Answer:
Step-by-step explanation:
We have to find out which two events are disjoint.
Two events are disjoint if both cannot happen simultaneously or Probability of both occurring is strictly 0.
a) Choose a student at random from a statistics class. Event A is that the student is a junior. Event B is that the student is a senior.
These are disjoint because a student cannot be a senior and junior both.
b) Choose a student at random from a statistics class. Event A is that the student is a psychology major. Event B is that the student is a statistics major.
Disjoint because same student cannot have psychology as well as statistics as major
c. Choose a student at random from a statistics class. Event A is that the student is at least 5'8" tall. Event B is that the student weighs at least 160 pounds.
These cannot be disjoint because there are chances for some students to be taller than 5 feet 8 inches and also having weight more than 160 lbs.
25 degrees since all triangles add up to 180 56 and 99 together make 155 and subtract 180 by 155 and you get 25
Answer:
x=0
Step-by-step explanation:
in the quadratic formula to only have one solution
for 
so we have
if we insert in the formula we have
since a≠0
