Answer:

P'(C) = 0.98

Step-by-step explanation:

Given that,

P(C) = 0.02 (The probability of getting C)

We need to find the complement of P(C) i.e. P'(C).

We know that,

P(C)+P'(C)=1

P'(C) = 1-P(C)

= 1-0.02

= 0.98

So, the complement of P(C) is equal to 0.98.

Flying lessons on weekdays cost m dollars per hour. Flying lessons on weekends cost 1.2m dollars per hour. The expression 9m+3(1
lbvjy [14]

Answer:

The cost of lesson for 9 hours on weekdays and 3 hours on weekends

Step-by-step explanation:

Given

Weekdays = \$m /hour

Weekends = \$1.2m/hour

Required

What does 9m + 3(1.2m) represent

The expression can be split to:

9m and 3(1.2m)

<u>For 9m:</u>

From the question, we understand that:

m = 1\ hour

Multiply both sides by 9

9 * m = 1\ hour * 9

9 m = 9\ hours

This means that:

9m = the cost of lessons for 9 hours on weekdays

<u>For 3(1.2m):</u>

From the question, we understand that:

1.2m = 1 \ hour

Multiply both sides by 3

3 * 1.2m = 1 \ hour * 3

3(1.2m) = 3 \ hours

This means that:

3(1.2m) = the cost of lessons for 3 hours on weekends

Hence, the expression represents:

The cost of lesson for 9 hours on weekdays and 3 hours on weekends

VashaNatasha [74]


After Greg makes the pudding 1 time, it takes him f(1)=2(0.8) ^{1}=1.6 hours to make it.

After Greg makes the pudding 2 times, it takes him f(2)=2(0.8) ^{2}=1.28 hours to make it

After Greg makes the pudding 2 times, it takes him f(3)=2(0.8) ^{3}=1.024 hours to make it

so The function is f(x)=2(0.8) ^{x}

Answer: f of x equals 2 multiplied by 0.8 to the power of x
