Assume that the average healthy body temperature is 98.249 degrees and the standard deviation is 0.733 degrees. How many standar

Leno4ka [110]

The standard deviation is 1.43 below the mean

<h3>How to determine the number of standard deviation?</h3>

The given parameters are:

Mean = 98.249

Standard deviation = 0.733

x = 97.2

To calculate the number of standard deviation below the mean, we use

$x = \bar x - n\sigma$

So, we have:

$97.2 = 98.249 - n * 0.7333$

Evaluate the like terms

$-1.049 =- n * 0.7333$

Divide both sides by -0.733

n =1.43

Hence, the standard deviation is 1.43 below the mean

Tom, Mary and Bill are aged 10,12 and 15 years respectively. They share 259 euros in the same ratio as their ages. Find how much

tigry1 [53]

Answer:

70 , 84 , 105

Step-by-step explanation:

sum their ages , 10 + 12 + 15 = 37

divide the amount by this sum to find the value of one part of the ratio.

259 ÷ 37 = 7 ← value of 1 part of the ratio , then

10 parts = 10 × 7 = 70 euros ← Tom's share

12 parts = 12 × 7 = 84 euros ← Mary's share

15 parts = 15 × 7 = 105 euros ← Bill's share

A diver begins at sea level and dives down 200 feet. He ascends at a steady rate of 12 and one-third feet per minute for 4. 5 mi

dexar [7]

The diver's depth is 55.485 feet.

Option B represents the correct expression of the equation.

<h2>How do you express the given condition in an equation form?</h2>

Given that the total depth is 200 feet. the steady rate of the diver is 12 and one-third feet per minute. The total time taken by the diver is 4.5 minutes.

The above condition can be written in equation form is given below.

Total Depth = Steady Rate per Minute $\times$ Total Time

$200 = (12+\dfrac {1}{3}) \times 4.5$

$200 - ((12+\dfrac{1}{3}) \times 4.5) = 0$

Hence we can conclude that option B represents the correct form of the equation.

Transactions to a computer database are either new items or changes to previous items. the addition of an item can be completed

sashaice [31]

P(<100) = P((new or change) & <100) = P(new & <100) + P(change & <100)

... = P(<100 | new)*P(new) + P(<100 | change)*P(change)

... = 0.90*0.70 + 0.20*0.30

... = 0.63 + 0.06 = 0.69 . . . . probability of completing a transaction in < 100 ms
