Conditional Statement: if p then q The converse form of a conditional statement is when: O p and q are switched, and both negate
nordsb [41]
<h3>2 Answers: </h3>

B)  p and the q are switched

C) Neither p or q is negated

========================================================

Explanation:

The original conditional "if P, then Q" has P and Q swap places to form the converse. So the converse would be "if Q, then P". We don't negate P, and we don't negate Q either.

Here is the full list

  • Original = If P, then Q
  • Converse = If Q, then P
  • Inverse = If not P, then not Q
  • Contrapositive = If not Q, then not P

Side notes:

  • The original and contrapositive are equivalent in truth value.
  • The converse and inverse are equivalent in truth value.

Is it Exponential distribution? or Geometric distribution?
slava [35]
<span>I believe you use the exponential distribution to find the probability of success (say "p"). Then, you use the Geometric(p) distribution using the "p" you calculated from the exponential as your success probability. Also, in b), you use a negative binomial (which is really just a generalized geometric distribution).

</span><span>Part c) Find the probability to 2 decimal places that the first success occurs in an odd-numbered observation. That is, the first success occurs in the 1st or 3rd or 5th or 7th (and so on) observation.</span>

Find the width of a rectangle with perimeter 92 and length 19
lora16 [44]

Answer:

Step-by-step explanation:

perimeter = l + b + l + b    or 2(l + b)

92 = 19 + 19 + 2b

92 = 38 + 2b

2b = 92 - 38

2b = 54

b = 54 / 2

b = 27

breadth or width of the triangle =  27

length = 19

Use the Graph of the parabola to fill in the table
Andre45 [30]

Answer:

a) Upwards

b) x = -1

c) (-1,-9)

d) x intercepts; (2,0) and (-4,0)

y intercept is (0,-8)

Step-by-step explanation:

a) As we can see, the parabola faces upwards

b) To find the axis of symmetry equation, we look at the plot of the graph and see the point through the vertex of the parabola that exactly divides the parabola into two equal parts

The x-value that the line passes through here is the point x = -1 and that is the equation of the axis of symmetry

c) The vertex represents the lowest point of the circle here,

As we can see, this is the point through which the axis of symmetry passes through to make a symmetrical division of the parabola

We have the coordinates of this point as

(-1,-9)

d) The intercepts

The x-intercept are the two points in which the parabola crosses the x-axis

We have this point as 2 and -4

The x-intercepts are at the points (2,0) and (-4,0)

For the y-intercept; it is the y-coordinate of the point at which the parabola crosses the y-axis and this is the point (0,-8)

1) How is unit rate related to slope or rise over run?
quester [9]
The unit rate is a ratio of change in y and into the change on x. It can also be the rise to run or the slope.
