Answer:
17.5
Step-by-step explanation:
The ratio of "pure drug" to liquid is 35:150
Therefore to evaluate for 75 mls we get the ratio 75/2150 or simply 1/2
we can then multiply 35 by the ratio 1/2
35/2=17.5
State the answer
In 75 mls there are 17.5 grams of pure drug
Answer:
I only have number 2 but it's C
Step-by-step explanation:
You have to multiply 18.25 3 times since volume of cube is length * width * height
Answer:
a)= 2
b) 6.324
c) P= 0.1217
Step-by-step explanation:
a) The mean of the sampling distribution of X`1- X`2 denoted by ux`-x` = u1-u2 is equal to the difference between population means i.e = 2 ( given in the question)
b) The standard deviation of the sampling distribution of X`1- X`2 ( standard error of X`1- X`2) denoted by σ_X`1- X`2 is given by
σ_X`1- X`2 = √σ²/n1 +σ²/n2
Var ( X`1- X`2) = Var X`1 + Var X`2 = σ²/n1 +σ²/n2
so
σ_X`1- X`2 =√20 +20 = 6.324
if the populations are normal the sampling distribution X`1- X`2 , regardless of sample sizes , will be normal with mean u1-u2 and variance σ²/n1 +σ²/n2.
Where as Z is normally distributed with mean zero and unit variance.
If we take X`1- X`2= 0 and u1-u2= 2 and standard deviation of the sampling distribution = 6.324 then
Z= 0-2/ 6.342= -0.31625
P(-0.31625<z<0)= 0.1217
The probability would be 0.1217
Answer:
A)
Step-by-step explanation:Quadratics
Answer:
it could be and to show his number two because it's running all those numbers up over and over again by percentage is that the end is going to give you a big number
Step-by-step explanation:
on the beginning is adding 200 + 50 we should give you 250 then is a 200 more so it was equals to 450 but then he asked you per week you get 50 extra so is basically 50 x 6 cylinder 6 weeks and I will give you a promise off $300 $300 + 450 equals to 750 each week is 10% so is basically equals to 50 so 50 + 50 + 50 + 50 or the easiest way is 50 * 6 I would go with answer to like I said because it's showing like a little of of a conversation was not given in any Solution on a specific number and that's the most closest one to like the whole problem
