Suppose Lin labels the books at a constant speed of s books per minute. There can be several equations written that represent the relationship between her labeling speed and the number of minutes it would take her to finish labeling. Complete the equation below: m = _________ where m is the number of minutes and s is the speed in books per minute.

Answers

Answer:

[tex]S = \frac{b}{m}[/tex]

Step-by-step explanation:

Given

[tex]Speed = s[/tex]

Required

Determine the expression for s

The speed is calculated as:

[tex]Speed = \frac{Number\ of\ books}{Time}[/tex]

Substitute S for speed

[tex]S= \frac{Number\ of\ books}{Time}[/tex]

Let the number of books be b and the time be m.

The expression becomes

[tex]S = \frac{b}{m}[/tex]

Hence, the expression for the scenario is:

[tex]S = \frac{b}{m}[/tex]

Standardized tests for certain subjects, given to high school students, are scored on a scale of 1 to 5. Let X represent the score on a randomly selected exam. The distribution of scores for one subject’s standardized test is given in the table.

A 2-column table with 5 rows. Column 1 is labeled score with entries 1, 2, 3, 4, 5. Column 2 is labeled probability with entries 0.18, 0.20, 0.26, 0.21, 0.15.

What is the mean of the distribution?

2.5
2.95
3
3.5

Answers

Answer:

The center for the distribution of scores appears to be higher for subject B than for subject A.

The mean of the distribution when X represent the score on a randomly selected exam so here the mean be like 2.95.

Calculation of the mean:

Since

Column 1 is labeled score with entries 1, 2, 3, 4, 5.

Column 2 is labeled probability with entries 0.18, 0.20, 0.26, 0.21, 0.15.

So it be like

= (0.18) (1) + (0.20) (2) + (0.26) (3) + (0.21) (4) + (0.15) (5)

= 0.18 + 0.40 + 0.78 + 0.84 + 0.75

= 2.95

Hence, the third option is correct.

Write the slope-intercept form of the equation of the line through the given points: (-2,13) and (4,1)

Answers

Answer: y = -2x + 9

Step-by-step explanation:

Points through which the line passes through are: (-2,13) and (4,1)

The slop intercept form will be in terms of:

y = mx + c

Find m first which is the slope:

= (Y₂ - Y₁) / (X₂ - X₁)

= (1 - 13) / (4 - (-2))

= -12 / 6

= -2

Using a point on the line and the slope, calculate c which is the y intercept:

Using point (-2,13) :

y = mx + c

13 = -2 * -2 + c

13 = 4 + c

c = 13 - 4

c = 9

Slope intercept form of line is therefore:

y = -2x + 9

He lay on his armour-like back, and if he lifted his head a little he could see his brown belly, slightly domed and divided by arches into stiff sections. The bedding was hardly able to cover it and seemed ready to slide off any moment. His many legs, pitifully thin compared with the size of the rest of him, waved about helplessly as he looked.(2)"What's happened to me?" he thought. It wasn't a dream. His room, a proper human room although a little too small, lay peacefully between its four familiar walls. A collection of textile samples lay spread out on the table -Samsa was a travelling salesman - and above it there hung a picture that he had recently cut out of an illustrated magazine and housed in a nice, gilded frame. It showed a lady fitted out with a fur hat and fur boa who sat upright, raising a heavy fur muff that covered the whole of her lower arm towards the viewer.(3)Gregor then turned to look out the window at the dull weather. Drops of rain could be heard hitting the pane, which made him feel quite sad. "How about if I sleep a little bit longer and forget all this nonsense", he thought, but that was something he was unable to do because he was used to sleeping on his right, and in his present state couldn't get into that position. However hard he threw himself onto his right, he always rolled back to where he was. He must have tried it a hundred times, shut his eyes so that he wouldn't have to look at the floundering legs, and only stopped when he began to feel a mild, dull pain there that he had never felt before.The above selection describes a scene that should be terrifying.
