Spinning a 4-section spinner twice can be described as which type of event? a. it is an independent event. the outcome of the second spin is unaffected by the outcome of the first spin. b. it is a dependent event. the outcome of the second spin is affected by the outcome of the first spin. c. it is a simple event. spinning a spinner is a single event. d. it is an impossible event. a spinner cannot land in two sections.

The correct answer is:

A) It is an independent event. The outcome of the second spin is unaffected by the outcome of the first spin.

Explanation:

Simple events are events in which one experiment happens at a time and there is only one single outcome. Since we are spinning the spinner twice, this is not a simple event.

Dependent events are events in which the outcome of one affects the other. This is not the case here.

Independent events are events in which the outcome of one event does not affect the probability of the next event. The result of the first spin will not influence the result of the second spin, so these are independent events.

Step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
