Determine the probability (as a decimal rounded to the nearest hundredth) of a normal random variable with a mean of three and a

mrs_skeptik [129]

Answer:

Step-by-step explanation:

On a normal distribution table with z scores of 0 as the mean and the standard deviations going to the right and to the left, 1.9 on the normal curve where 3 is the mean falls at -.275 on the normal curve where 0 is the mean. I used the normal distribution z table for negative values to get that .39165 lies to the left of -.275, which means that 1 - .39165 of the data lies to the right.

The probability that the value is greater than 1.9 is .60835, or as a percentage, 60.835%.

The difference of two numbers is always less than the sum of those two numbers

densk [106]

<h3>Answer: False</h3>

Here's a counter example to prove the statement to be incorrect

first number = 1

second number = -2

sum = 1 + (-2) = -1

difference = 1 - (-2) = 1 + 2 = 3

We see that the difference (3) is not smaller than the sum (-1)

Answer:

"Spin the spinner 5 times with 4 equal segments. One of the segment represents vanilla on either the spinner as well as three parts reflect certain flavors" would be the right answer.

Step-by-step explanation:

The actual probability of the given scenario will be:

⇒ $(1-\frac{1}{4})^5$

⇒ $(1-0.25)^5$

⇒ $(0.75)^5$

On solving the power, we get

⇒ $(0.237304)$

Now on multiplying the above value in 100, we get

⇒ $23.73$ %

Approximately 23.73% chance vanilla was not chosen by either of the five. So that the above is the right answer.

Answer:

$6^{15}$

Step-by-step explanation:

An outcome is a possible result of an event. Sample space is the set of all possible outcomes.

An event is a subset of the sample space.

Let B, W denotes blue-collar, white-collar respectively.

Let R, D and I denotes republican, democrat, or independent respectively.

Number of members of an adult soccer team = 15 members

To find:Number of outcomes

Sample space:

$S=\left \{ \left ( (x_1,y_1),(x_2,y_2),...,(x_{15},y_{15}) \right )|x_i\varepsilon \left \{ B,W \right \} \,,\,y_i\varepsilon \left \{ R, D, I \right \}\right \}$

So. n(S) = $\left ( 2\times 3 \right )^{15}=6^{15}$
