~Direct Variation When two variables are related in such a way that the ratio of their values always remains the same, the two variables are said to be in direct variation. In simpler terms, that means if A is always twice as much as B, then they directly vary. If a gallon of milk costs $3, and I buy 1 gallon, the total cost is $3.~

Answer:

Step-by-step explanation:

perpendicular (P) = 6

base (b) = 8

hypotenuse (h) =?

we know by using Pythagoras theorem,

h = $\sqrt{(p)^{2} + (b)^{2} } \\$

= $\sqrt{(6)^{2} + (8)^{2} } \\$

= 10

The probability distribution function for the discrete random variable where x is equal to the number of red lights drivers typi

Ivahew [28]

Using probability concepts, it is found that:

a) The missing value is 0.04.

b) The mean is of 0.37.

The distribution is given by:

$P(X = 0) = 0.76$

$P(X = 1) = 0.15$

$P(X = 2) = 0.05$

$P(X = 3) = x$

Item a:

The sum of <u>all the probabilities has to be 1</u>, that is:

$\sum_{i = 0}^{3} P(X = i) = 1$

Thus:

$0.76 + 0.15 + 0.05 + x = 1$

$0.96 + x = 1$

$x = 0.04$

The missing value is 0.04.

Item b:

The mean is given by the <u>sum of each outcome multiplied by it's probability</u>, thus:

$E(X) = 0(0.76) + 1(0.15) + 2(0.05) + 3(0.04) = 0.37$

The mean is of 0.37.

CAN ANYBODY HELP ME OUT

Answer:

Correct option is

b. If two sides and one included angle are equal in triangles PQS and PRS, then their corresponding sides are also equal.

Step-by-step explanation:

Here, we are given the line RQ, which is divided in two equal parts by a line PS which is perpendicular to RQ.

The foot S of PS is on the line RQ.

First of all, let us do a construction here.

Join the point R with P and P with Q.

Please refer to the attached image.

Now, let us consider the triangles PQS and PRS:

Side QS = RS (as given)

$\angle PSR = \angle PSQ = 90^\circ$

Side PS = PS (Common side in both the triangles)

Now, Two sides and the angle included between the two triangles are equal.

So by SAS congruence we can say that $\triangle PRS \cong \triangle PQS$

Therefore, the corresponding sides will also be equal.

RP = QP

RP is the distance between R and P.

QP is the distance between Q and P.

Hence, to prove that P is equidistant from R and Q, we have proved that:

b. If two sides and one included angle are equal in triangles PQS and PRS, then their corresponding sides are also equal.
