<span>Current
employee = 40 340
A year ago a company has 40 340 – 24% employee.
Simply subtract 24% of 40 340 from 40 340 to get the number of employees last
year
=> 24% = .24
=> 40 340 x 0.24
=> 9681.6
Now, let’s subtract this 24% from the total number of employees in the current
=> 40 340 – 9 681.6 or 9682
=> 30 658.4 or 30 658
The number of employee last year before it increased 24%</span>
Answer:
There is insufficient evidence to support the claim.
Step-by-step explanation:
What we need to do is calculate the z factor and see whether or not we can refute the manufacturer's claim.
We have to:
z = (p - pm) / [pm * (1-pm) / n] ^ (1/2)
where p is the probability of the random sample, 13% or 0.13 and pm the probability per microwave maker, that is, 10% or 0.1. n sample size which is 57.
When replacing, we are left with:
z = (0.13 - 0.1) / [0.1 * (1-0.1) / 57] ^ (1/2)
z = 0.75
This value corresponds in the normal distribution to 0.7734 (attached image), this value is very large to refute the above, it must give a value less than 0.05 to be able to be refutable.
Therefore there is insufficient evidence to support the claim.
Answer:
When x = 12, y = 4.
Step-by-step explanation:
If
y
∝
x
we can write that
y
=
k
⋅
x
where k is a constant of proportionality.
Using the values given:

k
⇒
k
=

The answer in here will be True beacuse the standard form of an equation means the right side of the equation should be 0, and everything on the left side.It is also true <span> while the elimination technique works for the addition and subtraction of equations, which is the case in here. Hope this works for you</span>
Answer:
cos210=cos(180+30)=−cos30=−√32 . sin210=sin(180+30)=−sin30=−12 . 3(cos210+isin210) =3(−√32)+3i(−12). −(32)√3−(32)i. My favourite way of seeing that sin30=12 and cos30=√32 is ...
