Lynna [10]3 years ago
6 0

Answer:

  1.  7.1 cm

  2.  10.9 cm

Step-by-step explanation:

1. You know the legs of a right triangle must be shorter than the hypotenuse. The only answer choice shorter than 8 cm is 7.1 cm.

__

2. By the Law of Sines, ...

  AB/AC = sin(ACB)/sin(B)

  AB = AC·sin(72°)/sin(38°) = 1.545·AC

The approximate value of AC from problem 1 is sufficient to get you close to the answer.

  AB ≈ 7.1×1.545 ≈ 10.9 . . . cm

Rewriting standard form to slope intercept
algol [13]

If you're asking how, here's an example

A standard form equation is when it is set up.

Ax + By = C.

6x + 2y = 4.

A slope-intercept form equation is when it is set up y=mx+b.

Y = - 3x + 2.

4y = -8x + 16 then divide all by 4.

y = -2x + 4 slope form.

Find the difference.<br><br> (4−5y)−2(3.5y−8)
MAVERICK [17]

Answer:

-12y + 20

Step-by-step explanation:

First, you simplify each term:

apply the distributive property:

4 - 5y - 2 (3.5y) - 2 x -8

Multiply 3.5 by -2:

4 - 5y - 2 (3.5y) - 2 x -8

Multiply -2 by -8:

4 - 5y - 7y +16

Next, we simplify by adding terms:

Add 4 + 16:

-5y - 7y + 20

Subtract 7y from 5y:

-12y + 20

Hence the simplified form is -12y + 20

To estimate the difference we need four averages for the categorized groups i.e., control group before change, control group aft
nataly862011 [7]

Answer:

b. False

Step-by-step explanation:

In a research study, when a researcher wants to find the impact of a new treatment, then the researcher randomly divides the the study participants into two groups. The groups are :

-- control group

-- treatment group

The control group is a group that is used to establish the cause-and-effect relationship by making the effect of an independent variable isolate. It receives no treatment or some standard treatment for the which the effect is already known.

The treatment group receives the treatment for which the effect the researcher is interested in.

Thus the averages of the four categorized groups are not required for estimating the difference.

Therefore, the answer is FALSE.
