A 150 pound woman would receive 24grams of a certain medicine. How many grams should 120 pound woman receive?
shtirl [24]

Answer:

19.2 grams

Step-by-step explanation:

Assuming it is a straight proportion, then the givens are

w1 = 150 pounds

m1 = 24 grams

w2 = 120 pounds

m2 = x

m = medication amount.

w = weight

Equation

m1/w1 = m2/w2

Solution

24/150 = x / 120                  Multiply both sides by 120

24 * 120/150 = x 120 /120  

2880/150 = x                       Do the division

19.2 grams = x                      The amount the 120 pound woman should receive.

Calculate the product 45.67x32.58 rounded to the nearest penny
serg [7]

We assume the monetary amount is a number such that the hundredths place represents a penny. (It's not billions of dollars, for example.)

45.67×32.58 = 1,487.9286 ≈ 1,487.93

_____

Any calculator can give you the product. Most will round the number for you if you specify a 2 decimal digit display.

The thousandths digit of the product (8) is more than 4, so the hundredths digit (2) is increased by 1 (to 3) as the digits to its right are dropped.

Dmitry_Shevchenko [17]

Answer:

The critical value for the 95% confidence interval is z = 1.96.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha

So it is z with a pvalue of 1-0.025 = 0.975, so z = 1.96.

The critical value for the 95% confidence interval is z = 1.96.
