If the probability of an event happening is 86/99, what are the odds against it happening?

1 answer:

3 0

P(Event Happening) + P(Event Not Happening) = 1

P(Event Not Happening) = 1 - P(Event Happening)

P(Event Not Happening) = 1 - 86/99

P(Event Not Happening) = 13/99

Determine which answer choice matches the dot plot you drew?

Vesnalui [34]

Answer:

Step-by-step explanation:

Given data are :

{1,2,2,2,2,4,4,5,6,6,8,8,8,10}

1 appears only once so there will be 1 point above number 1 in the dot plot.

Then choice B or C or D are possible choices.

2 appears 4 times so there will be 4 points above number 4 in the dot plot.

Then choice B or C or D are possible choices.

4 appears 2 times so there will be 2 points above number 2 in the dot plot.

Then choice C or D are possible choices.

5 appears once once so there will be 1 point above number 5 in the dot plot.

Only choice that satisfies those results is C.

Hence correct answer is C.

The area of a playground is 168 yd2. The width of the playground is 2 yd longer than its length. Find the length and width of th

77julia77 [94]

Answer:

Length = 12yards

Width = 14yards

Sum = 26yards

Step-by-step explanation:

Let assume the play ground is rectangular in form.

Area of a rectangle = length × width

Given area of the playground = 168yd²

If the width of the playground is 2yd longer than its length, then:

W = L+2

Substituting W = L+2 into the formula above we have:

A = L × (L+2)

A = L²+2L

168 = L²+2L

L²+2L-168 = 0

L²+14L-12L-168 = 0

L(L+14)-12(L+14) = 0

(L-12)(L+14) = 0

L-12 = 0 and L+14 =0

L = 12 and -14

Taking the positive length, L = 12yards

If Length = 12yards

W = L+2

W = 12+2

Width = 14yards

Sum of the length and width will be:

L+W= 12+14

= 26yards
