Answer:

The answer for this question would be 85 and 17/20 or /20

Step-by-step explanation:

You must first find the LCD of these terms (everything that is separated by the addition signs).

The LCD is 20 because:

2 x 10 = 20

5 x 4 = 20

4 x 5=20

and there is no number lower than 20 that all of these numbers share in their multiplication table.

Now you must multiply every term by the number you used to make its denominator 20. Since 2 x 10 = 20, the new term would be:

60 10/20

Since 5 x 4 = 20, the new term would be:

4 12/20

Since 4 x 5 = 20, the new term would be:

20 15/20

Now we put all the whole numbers and numerators together to get:

60 + 4 + 20 = 84 - whole numbers

10 + 12 + 15 = 37 - numerators

84 37/20 = 85 17/20 or 1717/20

Determine whether the random variable is discrete or continuous. In each case, state the possible values of the random variable

yan [13]

Answer:

a) C. The random variable is discrete. The possible values are xequals0, 1, 2,....

b) B. The random variable is continuous. The possible values are x greater than or equals 0.

Step-by-step explanation:

Discrete variables are countable in a finite amount of time. Continuous variables can be infinitely many. They rather assume values in a range.

(a) Is the number of hits to a Web site in a day discrete or continuous?

C. The random variable is discrete. The possible values are x equals 0, 1, 2,....

(b) Is the weight of a Upper T dash bone steak discrete or continuous?

B. The random variable is continuous. The possible values are x greater than or equals 0.

Is line 1 (1,5) (3,-2) and like 2 (-3,2) (4,0) perpendicular of parallel?

Lera25 [3.4K]

Slope Formula: $\frac{y_2-y_1}{x_2-x_1}$

So remember that perpendicular lines have slopes that are negative reciprocals to each other and parallel lines have the same slope. To find out if they are either parallel or perpendicular, plug the pair of points into the slope formula to find their slopes:

$\textsf{Line 1}\\\\\frac{5-(-2)}{1-3}=-\frac{7}{2}\\\\\textsf{Line 2}\\\\\frac{0-2}{4-(-3)}=-\frac{2}{7}$

Since these slopes aren't the same nor are they negative reciprocals to each other, the lines are neither parallel nor perpendicular.
