On the number line, the distance between negative 11 and positive 7 is <em>18 units</em>.

Choice A: The absolute value of (-11 - 7) = absolute value of (-18) = 18.

Choice C: The absolute value of [ 7 - (-11) ] = absolute value of (7+11) = 18.

'A' and 'C' are both the same number, and it's the correct answer to the question.

A school administrator asks each student if they participate in a sport and if they participate in a club. The results are shown

Aleks [24]

Probabilities are used to represent the possibilities of events.

The probability that a student participates in a club given that he participates in sports is 0.6561

The required probability is represented as; P(Club | Sport)

And it is calculated using:

$P(Club | Sport) = \frac{n(Club\ n\ Sport)}{n(Sport)}$

From the table, we have:

$n(Club\ n\ Sport) = 620$

$n(Sport) = 945$

So, the equation becomes

$P(Club | Sport) = \frac{620}{945}$

$P(Club | Sport) = 0.6561$

Hence, (d) 06561 is correct.

Answer:

The pulse rate is 84.54bpm

Step-by-step explanation:

Given

$\^{} y = 17.8 + 0.940x$

Required

Find $\^{}y$ when $x = 71$

Substitute 71 for x in: $\^{} y = 17.8 + 0.940x$

$\^{} y = 17.8 + 0.940 * 71$

$\^{} y = 17.8 + 66.74$

$\^{} y = 84.54$

<em>The pulse rate is 84.54bpm</em>
