Answer:

0.31% = 0.0031 in decimal form.

Step-by-step explanation:

Percent means 'per 100'. So, 0.31% means 0.31 per 100 or simply 0.31/100. If you divide 0.31 by 100, you'll get 0.0031 (a decimal number).

Which are the better statistics to use to compare the team scores? Team A's scores 58 60 62 64 66 68 70 72 74 76 78 80 82 84 86

Alenkasestr [34]

The better statistics that can be used to compare the scores of the two teams are: D. Median and IQR.

The diagram given shows two box plots representing the data of the two team's scores.

Box plots displays the 5-number summary, namely:

Minimum data value
Maximum data value
Median
First Quartile $(Q_1)$ , and
Third Quartile $(Q_3)$

The Interquartile Range (IQR) of the data can also be calculated by finding the difference between the First Quartile $(Q_1)$ , and the Third Quartile $(Q_3)$ .

The Interquartile Range (IQR) helps us to determine the variability of the data set.

The median that is gotten from the box pot measures the center tendency of the data.

Both median and IQR are better statistics that can be easily gotten from box plots to compare the team scores.

Therefore, the better statistics to use for comparing the scores of the teams are: D. Median and IQR.

Verify the identity. sine x times secant x equals tangent x To verify the identity, start with the more complicated side and tr

liraira [26]

<h2> $\sin x \times \sec x=\tan x,$ proved.</h2>

Step-by-step explanation:

To verify, the identity $\sin x \times \sec x=\tan x$ .

L.H.S. $=\sin x \times \sec x$

We know that,

$\sec A\cos A=1$

⇒ $\sec A=\dfrac{1}{\cos A}$

Now, L.H.S., becomes

$=\sin x \times \dfrac{1}{\cos x}$

$=\dfrac{\sin x}{\cos x}$

= $\tan x$

= R.H.S., verify.

Thus, $\sin x \times \sec x=\tan x,$ proved.

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
