False , Combining a coin toss and a roll of a die makes a simple event.

In statistics, what does a probability mean?

The probability serves as a gauge for how likely an event is to occur. It gauges how likely an event is.
P(E) = Number of Favorable Outcomes/Number of Total Outcomes is the formula for probability.
Mathematics' study of random events is known as probability, and there are four primary types of probability: axiomatic, classical, empirical, and subjective.
Since probability is the same as possibility, you could say that it is the likelihood that a specific event will occur.

False , Combining a coin toss and a roll of a die makes a simple event.

A true statement is "For data at the interval level, you CAN calculate meaningful differences between data entries."

The circumference of the ellipse approximate. Which equation is the result of solving the formula of the circumference for b?

Serhud [2]

Answer:

$b = \sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}}$

Step-by-step explanation:

Given - The circumference of the ellipse approximated by $C = 2\pi \sqrt{\frac{a^{2} + b^{2} }{2} }$ where 2a and 2b are the lengths of 2 the axes of the ellipse.

To find - Which equation is the result of solving the formula of the circumference for b ?

Solution -

$C = 2\pi \sqrt{\frac{a^{2} + b^{2} }{2} }\\\frac{C}{2\pi } = \sqrt{\frac{a^{2} + b^{2} }{2} }$

Squaring Both sides, we get

$[\frac{C}{2\pi }]^{2} = [\sqrt{\frac{a^{2} + b^{2} }{2} }]^{2} \\\frac{C^{2} }{(2\pi)^{2} } = {\frac{a^{2} + b^{2} }{2} }\\2\frac{C^{2} }{4(\pi)^{2} } = {{a^{2} + b^{2} }$

$\frac{C^{2} }{2(\pi )^{2} } = a^{2} + b^{2} \\\frac{C^{2} }{2(\pi )^{2} } - a^{2} = b^{2} \\\sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}} = b$

∴ we get

$b = \sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}}$

Z - 1,092.8 = 1,200 A. z = 2,292.8 B. z= 2,193.8 C. z= 2,291.2

OleMash [197]

Answer:

A. z = 2292.8 is your answer

Step-by-step explanation:

Isolate the variable (z). Note the equal sign, what you do to one side, you do to the other. Add 1092.8 to both sides

z - 1092.8 (+1092.8) = 1200 (+1092.8)

z = 1200 + 1092.8

z = 2292.8

A. z = 2292.8 is your answer

May someone help me with this?

elena-14-01-66 [18.8K]

I am putting this into rows. Ex: row one has 0. row two has blank and seven.

1: 0

2: 9 7

3: - 9 6

4: 1 3

5: - 1 2

6: 1

So the answer on top would be 8 1 r 1.
