Put these numbers in order from least to greatest 12%, -1/2, 0, -0.22, 0.56
uysha [10]

Answer: -1/2, -0.22, 0, 12%, 0.56

Step-by-step explanation:

-1/2 is equal to -0.50, making it the number with the least value.

-0.22 is closer to 0 than -0.50, meaning it is greater then -0.50 and less than 0.

0 is between the negative and positive numbers, giving it the spot that it has.

12% is equivalent to 0.12, meaning it is more than 0, and less than 0.56, which is the greatest number.

0.56 has more value than any other number in the problem, meaning it goes last in the order.

Find the mean and the median of this data set: 8, 6, 6, 3, 72, 7, 4, 2
icang [17]

Answer:

median: 6  ;  mean: 13.5

Step-by-step explanation:

The median is where you line up the numbers from least to greatest and add the 2 that are left since it was an even number and you get 6. The mean is where you add all 8 numbers and divide by 8, since that is how many numbers there are.

Doc Brown’s DeLorean has three crucial systems that are required for a successful trip: combustion engine, time circuits, and fl
Nesterboy [21]

Step-by-step explanation:

The total probability that the DeLorean makes the trip is:

P = P(engine) × P(at least 1 time circuit) × P(at least 2 capacitors)

P = P(engine) × (1 − P(0 time circuits)) × P(at least 2 capacitors)

P = 0.94 × (1 − ₄C₀ 0.75⁰ 0.25⁴) × (₃C₂ 0.8² 0.2¹ + ₃C₃ 0.8³ 0.2⁰)

P = 0.94 × (1 − 0.25⁴) × (0.384 + 0.512)

P = 0.83895

The reliability of the DeLorean is approximately 83.9%.

5. Henry hit 3 more than half as many home runs as Jack hit last season. Henry hit a total of 8 home runs. a. Make Sense and Per
Evgesh-ka [11]

Answer:

a.  3+\frac{x}{2} =8

b.  x = 10

Step-by-step explanation:

a.  The number of home runs hit by Jack last season = x

It is given that Henry hit 3 more than half as many home runs as Jack hit.

Half of the runs hit by Jack = \frac{x}{2}

3 more than half the runs =  3+\frac{x}{2}

So, the number of home runs hit by Henry =  3+\frac{x}{2}

But, it is given that Henry hit a total of 8 runs.

Therefore,  3+\frac{x}{2} =8

b.   3+\frac{x}{2} =8

Subtract 3 from both sides.

\frac{x}{2} =8-3

= 5

x = 5 × 2

= 10

Hence, Jack hit 10 runs in the last season.
