Total possible outcomes = 36
Total possible outcomes with sum equal to 4 = 3
{1, 3} {2, 2}, (3, 1}

P(sum equal to 4) = 3/36 = 1/12

If you throw it 1000 times,
Number of times expected to have a sum of 4 = 1/12 x 1000 = 83 times

Answer: About 83 times

Solve the proportional equation 3/r = 5/r+3
romanna [79]

Answer:

r=9/2 or 4.5

Step-by-step explanation:

First of all our goal is to get R by itself

by cross multiplying we get,

(r+3)*3=5r

by distributive property we get

3r+9=5r

substracting 3r from both sides we get

9=2r

by dividing by 2 in both sides we get

r=9/2 or 4.5

Can someone answer this question please answer it correctly if it’s corect I will mark you brainliest
nata0808 [166]

Answer:

2) The second option (the bag)

8) 36 desserts

9) HH, HT, TT, TH: 1/4

Step-by-step explanation:

2)

O -  Not certain, it is possible to choose a green marble

O - Certain, all the numbers in the bag are less than 100, so the one you choose must be less than 105

O - Not certain, the spinner will not always land on the 10th letter of the alphabet

O - Not certain, the sum of the number cubes will not always be 12, depending on the number you roll

8)

Size: Small cup, Large cup, Regular cone, Waffle cone

Flavors: Vanilla, Cookies & Cream, Mint Chocolate

Toppings: Fudge, Sprinkles, Caramel sauce

With a small cup:

Small cup, Vanilla, Fudge

Small cup, Vanilla, Sprinkles

Small cup, Vanilla, Caramel sauce

Small cup, Cookies & Cream, Fudge

Small cup, Cookies & Cream, Sprinkles

Small cup, Cookies & Cream, Caramel sauce

Small cup, Mint chocolate, Fudge

Small cup, Mint chocolate, Sprinkles

Small cup, Mint chocolate, Caramel sauce

There are 9 options with a small cup

There are 4 possibilities for types of cups

Multiply

4 * 9

36

9)

The question is asking what would the sample space be of flipping a coin 2 times. You will not always alternate (heads, tails, heads, tails) when flipping a coin. This means that all of the possibilities are HH, HT, TT, TH.

Chance of getting heads = 1/2

Chance of getting tails = 1/2

Chance of getting 2 heads (divide by 2) = 1/4

Chance of getting 2 tails = 1/4

HH, HT, TT, TH: 1/4

27 list the factor is this prime or composite
Pachacha [2.7K]

The factors of  27  are  1,  3,  9, and  27 .

A prime number has only two factors.  They are ' 1 ' and itself.
27  has four factors, so it's not prime.
