In baseball batting averages are expressed as decimal numbers if the player has had 8 hits out of 20 a bats what is his batting average and what percentage of the time does the player get a hit

Answers

Answer 1

Answer: To find the batting average divide the number of hits by the number of at bats.
Batting average = 8 / 20 = 0.400, which equals 40% of the time they get a hit.

How do I simplify 3³×3⁴÷3²

From the exponent's formula, the simplified form of the given question $3^(2) * 3^(4) / 3^(2)$ is 243.

What is the exponent's formula?

Exponents formulas help solve exponents represented by $\rm x^(n)$ multiplying by itself n times. here, x is called the base and n is the exponent or power. $\rm x^(n)$ is read as x raised to the power of n.

The formula required

$\rm a^(x) * a^(y) = a^(x+y)$

$\rm a^(x) / a^(y) = a^(x-y)$

So, by applying the above exponent's formulas

$3^(3) * 3^(4) / 3^(2)\n= 3^(3+4) / 3^(2)\n= 3^(7) / 3^(2)\n= 3^(7-2) \n= 3^(5) \n= 243$

Hence, the simplified form of the given question $3^(2) * 3^(4) / 3^(2)$ is 243.

Answer:

The answer to your question is:

1x² - 6x + 8 - 9 / (x³ - 5x² + 2x -1)

Step-by-step explanation:

Divide x³ - 5x² + 2x -1 by x + 1

1 -5 +2 -1 -1

-1 +6 -8

1 -6 +8 -9

1x² - 6x + 8 - 9 / (x³ - 5x² + 2x -1)

PLSSSSSSSSSSS HEEEEEELP????The mean of a set of normally distributed data is 600 with a standard deviation of 20. What percent of the data is between 580 and 620?

Answers

Answer:

The percentage of the data between 580 and 620 is 68.26 %

Step-by-step explanation:

Given,

Mean, $\mu$ = 600,

Standard deviation, $\sigma$ = 20,

Using the equation,

$z-score=(x-\mu)/(\sigma)$

Z-score for the data 580 = $(580-600)/(20)$

$=(-20)/(20)$

$=-1$

While, the z-score for the data 620 = $(620-600)/(20)$

$=(20)/(20)$

$=1$

Using normal distribution table,

P(580 < z) = 0.1587

Also, P(620 > z) = 0.8413

Hence, the percent of the data is between 580 and 620 = P(620 > z) - P(580 < z)

= 0.8413 - 0.1587

= 0.6826

= 68.26 %

z = (X-Mean)/SD
z1 = (580-600)/20 = - 1
z2 = (620-600)/20 = + 1
According to the Empirical Rule 68-95-99.7
Mean +/- 1*SD covers 68% of the values
Therefore, required percent is 68%

A car drives 12 miles north, turns, and then drives 8 miles east. How far is the car from its starting point? a. Use the Pythagorean theorem to find the length of the missing side. Be sure to indicate which root represents the answer and write the answer in simplest radical form.
b. Use a calculator to change the answer to decimal form. Round the answer to the nearest tenth. Using this decimal number, write a sentence to explain the meaning of the answer in this situation.

Answers

a. Using the pythagorean theorem : c = √(a² + b²)
Let: a = 12; b = 8

Substituting the values:
c = √(12² + 8²)
c = √(144 + 64)
c = √(208)
c = √(16)(13)
c = +-4√13

The positive root indicates the answer. The car is 4√13 miles from the starting point.

b. Using a calculator to simplify c = +-4√13 in decimal form would yield:
c = 14.42 miles.

The car is now 14.42 miles away from the starting point.
