Answer and explanation:

There's 3 one dollar bills

2 five dollar bills

and 2 ten dollar bills

and 1 twenty dollar bill

3+2+2+1=8

Part A: The probability of selecting 5 is 2/8 and the probability of selecting 10 is also 2/8 and both of them are the same, 1/4.

Part B: The probability of selecting a one dollar bill is 3/8 and the probability of selecting a twenty dollar bill is 1/8 because there are 3 one dollar bills in 8 bills and 1 twenty one dollar bill in 8 bills only.

Point P on the number line shows Lara's score after the first round of a quiz: A number line is shown from negative 8 to 0 to po
Luda [366]

Answer:

The correct group of answer is D) 3 + (−4) = −1, because −1 is 4 units to the left of 3

Step-by-step explanation:

Consider the provided information.

Point P on the number line shows Lara's score after the first round of a quiz:

Point P is shown on 3.

That means after the first round her total was 3.

In round two, she lost 4 points.

Therefore, she score −4 points in 2nd round

To find the total points at the end of round 2, we need to add -4 to 3.

3+(−4)=−1

Here −1 is 4 units to the left of 3.

Hence, the correct group of answer is D) 3 + (−4) = −1, because −1 is 4 units to the left of 3

The value of a certain car decreases by 16% each year. What is the 1⁄2-life of the car?
svet-max [94.6K]

Answer:

The half life of the car is 3.98 years.

Step-by-step explanation:

The value of the car after t years is given by the following equation:

V(t) = V(0)(1-r)^{t}

In which V(0) is the initial value and r is the constant decay rate, as a decimal.

The value of a certain car decreases by 16% each year.

This means that r = 0.16

So

V(t) = V(0)(1-r)^{t}

V(t) = V(0)(1-0.16)^{t}

V(t) = V(0)(0.84)^{t}

What is the 1⁄2-life of the car?

This is t for which V(t) = 0.5V(0). So

V(t) = V(0)(0.84)^{t}

0.5V(0) = V(0)(0.84)^{t}

(0.84)^{t} = 0.5

\log{(0.84)^{t}} = \log{0.5}

t\log{0.84} = \log{0.5}

t = \frac{\log{0.5}}{\log{0.84}}

t = 3.98

The half life of the car is 3.98 years.
