Lance has three times as many pencils as Nick, and they have 84 pencils together. How many pencils does each of them have?
STALIN [3.7K]

Answer:

Let Lance represented by L and Nick represented by N

As per the statement:

Lance has three times as many pencils as Nick

⇒L = 3N         .....[1]

It is also given that:

They have 84 pencils together.

⇒L+N = 84               .....[2]

Substitute the equation [1] into [2] we have;

3N+N = 84

⇒4N = 84

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

If f(x)=3-2x and g(x)=1/x+5, what is the value of (f/g)(8)?
dalvyx [7]

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...

\frac{1}{8}(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

Large samples of women and men are​ obtained, and the hemoglobin level is measured in each subject. here is the​ 95% confidence
Daniel [21]

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.
