1 mg = 1,000 mcg → 1 mcg = 0.001 mg
0.075 mcg = 0.075 · 0.001 mg = 0.000075 mg
<h3>Answer: 0.075 mcg = 0.000075 mg</h3>
Answer:
Value of x = 400
Step-by-step explanation:
Joint variation states that describes a situation where a variable depends on two (or more) other variables, and varies directly with some of them.
Given: x varies directly with y and z.
i.e
and ![x \propto z](https://tex.z-dn.net/?f=x%20%5Cpropto%20z)
then we have the joint variation as;
......[1] where k is the constant variation.
Substitute the value of x =1200 when y =20 and z = 30 to solve for k;
![1200 = k (20)(30)](https://tex.z-dn.net/?f=1200%20%3D%20k%20%2820%29%2830%29)
Simplify:
![1200 = 600k](https://tex.z-dn.net/?f=1200%20%3D%20600k)
Divide both sides by 600 we get;
![k = 2](https://tex.z-dn.net/?f=k%20%3D%202)
Now, substitute k =2 , y =10 and z = 20 to find x;
Using [1] we have;
![x = 2 \times (10)(20) = 2 \times 200](https://tex.z-dn.net/?f=x%20%3D%202%20%5Ctimes%20%2810%29%2820%29%20%3D%202%20%5Ctimes%20200)
Therefore, the value of x is, 400
Answer:
Step-by-step explanation:
3=7k
Meaning k = 3/7
7=m/2
Meaning m = 7*2 = 14
Therefore mk = 3/7*14 = 6
Answer:
Based on given data, we can say with 95% confidence that the female employees at this company average between $110 less and $10 less per week than the male employees.
Step-by-step explanation:
Sample 1 for female
Sample 2 for male
Confidence = 90%
Difference in mean weekly salary of all female employees and the mean weekly salary of all male employees = µ₁- µ₂
So based on above given data, we can say with 95% confidence that the female employees at this company average between $110 less and $10 less per week than the male employees.
