Hello.

1. The outcome would be 1/7 beacuse there are 7 days in a week and there is only one day.

2. 0.14285714 and 1/7

3. The answer is neither likley or unlikley.
Its not impossble becasue there is a good chance that could happen.
It wouldnt be likley beacase a 1 to 7 ratio is pretty small when there is 6 more oprtions.
And not unlikley or likley becasue there is a good chance it could happen so the answer would be unlikley.

Have a good day.

If Body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.20°F anda standard deviation of 0.93°F.

lisov135 [29]

Step 1

Given; If Body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.20°F and a standard deviation of 0.93°F.

Using the empirical rule, what is the approximate percentage of healthy adults with body temperatures between 96.34°F and 100.06°F?

Step 2

$P(96.34The empirical rule states that 95% of the data fall within two standard deviations of the mean. Thus, 95% of healthy individuals have body temperatures between 96.34F and 100.06F.Answer;[tex]95\text{\%}$

the hoop rotates through qan angle of 3/2 pie radian in 1 second how many revolutions does the hoop make in 1 minute

timofeeve [1]

A revolution is a full go-around the circle, namely a 2π angle, as opposed to pie, but yours sounds more delicious.

so, we know it does 3/2 π in 1 second, how many π does it do in 60 seconds(1 minute) ?

$\bf \begin{array}{ccll}
radians&seconds\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{3\pi }{2}&1\\\\
r&60
\end{array}\implies \cfrac{\frac{3\pi }{2}}{r}=\cfrac{1}{60}\implies \cfrac{\frac{3\pi }{2}}{\frac{r}{1}}=\cfrac{1}{60}$

$\bf \cfrac{3\pi }{2}\cdot \cfrac{1}{r}=\cfrac{1}{60}\implies \cfrac{3\pi }{2r}=\cfrac{1}{60}\implies \cfrac{3\pi \cdot 60}{2}=r\implies 90\pi =r\\\\
-------------------------------\\\\
\textit{how many times }2\pi \textit{ goes into }90\pi ?\qquad \cfrac{90\pi }{2\pi }\implies 45$

6) Find the surface area of the rectangular prism.

ANEK [815]

Answer:

Step-by-step explanation:

To find the surface area of a rectangular prism, measure the length, width, and height of the prism. Find the area of the top and bottom faces by multiplying the length and width of the prism. Then, calculate the area of the left and right faces by multiplying the width and height.
