Answer:
Let Lance represented by L and Nick represented by N
As per the statement:
Lance has three times as many pencils as Nick
⇒
.....[1]
It is also given that:
They have 84 pencils together.
⇒
.....[2]
Substitute the equation [1] into [2] we have;

⇒
Divide both sides by 4 we have;
N = 21
Substitute this in [1] we have;
L = 3(21) = 63
Therefore, Lance has 63 pencils and Nick has 21 pencils
Answer:
60
Step-by-step explanation:
Answer:
The answer is -9
Step-by-step explanation:
First we have to find the value for g(8) so that we can plug its solution into f(x).
So...
(8) + 5
1 + 5
6
So now we plug in 6 into f(x) since 6 was our solution to g(x)
3 - 2(6)
3 - 12
-9
Answer:
1. The mean hemoglobin level in men is not equal to the mean hemoglobin level in women and
2. There is more hemoglobin in the average man than in the woman
Step-by-step explanation:
The confidence interval is from
-1.76 g/dl < μ₁ - μ₂ < -1.62 g/dl
Here we note that the range in the confidence interval for the difference between the two means lie in the negative part of the number line which is indicative of that μ₁ - μ₂ ≠ 0 or μ₁ ≠ μ₂
That is the statistic of the confidence interval implies that the mean hemoglobin level in men is not equal to the mean hemoglobin level in women and
That there is more hemoglobin in the average man than in the woman.
