Answer: u.(v+w) = -20
Step-by-step explanation:
Given;
u = -i+j
v = 10i-2j
w = -8j
v+w = 10i-2j +(-8j)
v+w = 10i-10j
u .(v+w) = (-i+j).(10i-10j)
= -1×10 + 1 ×-10
= -10-10
u.(v+w) = -20
Answer:
5/13 (irreducible)
Step-by-step explanation:
1/3=2/6=3/9=4/12 are all thirds of the total.
Answer:
Standard deviation = 7.76
Step-by-step explanation:
The formula for determining standard deviation when dealing with population proportion is expressed as
Standard deviation = √npq
Where
n represents the number of samples from the population.
p represents the probability of success.
q represents the probability of failure.
From the information given,
n = 500 policyholders
p = 14% = 14/100 = 0.14
q = 1 - 0.14 = 0.86
Standard deviation = √500 × 0.14 × 0.86 = 7.76
Answer:
Answer A : 235.16
Step-by-step explanation:
Notice that in the original number (43.92), the 3 is located in the column of the units. So we are looking for a number that contains a 3 in ten times as much, that is a number that contains a 3 in the column of the tenths.
From the four given choices, the only one with a 3 in the column of the tenths is the one in answer A: 235.16
