How do i wright an algebraic expression from a word problem. Such as "The product of a number w and 737

1 answer:

4 0

The 'product' of two numbers lets you know that you'll be multiplying them. So the product of a number w and 737 is w x 737. That can be rewritten as 737w.

What is the value of 14 – 2 • 3 + 42? someone help me understand

xxMikexx [17]

Based on PEMDAS, in this expression, we need to do multiplication first, which is 2 times 3, which is 6. Now, the expression is 14-6+42. 14-6 is 8, and 8+42 is 50, so the answer is 50.

Hope this helps!

A rain barrel is full of water and used to water the garden. The rain barrel loses water at the rate 2.5 gallons of water per mi

Answer: y - 37.5 = 2.5 ( x - 7)

Explanation:

1) The point-slope form is has this form:

y - y1 = m (x - x1)

Where m is the slope or rate of change and x1, y1 are the coordinates of the point.

2) you are told that the the rate of change of water (m) is 2.5

m = 2.5

3) The point is given by that after 7 min the rain barrel contains 37.5 gallons. This is:

x1 = 7
y1 = 37.5

4) Replace those value in the point-slope model:

y - 37.5 = 2.5 ( x - 7)

That is the point-slope model or equation.

Many consumer groups feel that the U.S. Food and Drug Administration (FDA) drug approval process is too easy and, as a result, t

Zigmanuir [339]

Answer:

If we reject the null hypothesis based on the evidence, then our conclusion should be Option c.

If we do not reject the null hypothesis based on the evidence, then our conclusion should be Option a.

Step-by-step explanation:

We are given that the FDA wants to set up a hypothesis test to show that the new drug is safe before approving it by assuming it to be unsafe.

So, Null hypothesis, $H_0$ = New drug is unsafe

Alternate Hypothesis, $H_1$ = New drug is safe

Now, if we reject the null hypothesis based on the evidence, then our conclusion should be that :

There is sufficient evidence to believe that the new drug is safe because rejecting null hypothesis means that alternate hypothesis is accepted with required evidence.

And If we do not reject the null hypothesis based on the evidence, then our conclusion should be that :

There is insufficient evidence to believe that the new drug is safe because not rejecting null hypothesis means that we are not ready with enough evidence to assume that new drug is safe.
