Answer:

1 + i

Step-by-step explanation:

Given that A is a 3 * 3 singular matrix

one of its eigenvalue ( λ1 ) = 1 - i

Given that the determinant of a singular matrix is = 0

therefore the second eigen value ( λ2 ) = 1 + i

1 - i + 1 + i  = 0

F = 9/5C + 32

F = 9/5(40) + 32
F = 72 + 32
F = 105

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
