Answer:
<u>A slope of 0.5.</u>
Step-by-step explanation:
Each coin toss has a 50% probability of being heads. Therefor, the histogram plot should have a slope of 0.5. To illustrate, graph the predicted probabilities of at least two sets of coin tosses, such as 6 and 16. The probable number of heads would be 3 and 8. Plot those two points and draw the line. <u>The slope of that line will be 0.5.</u>
See the attachment. I graphed more than two points, since it was easy. But you really only need two if you know it is a straight line function. Graph a third just to be certain.
Answer:
Cost of 1 goggles = $20
Cost of 1 mask = 15
Step-by-step explanation:
Given:
Cost of 2 goggles and 1 mask = $55
Cost of 1 goggles and 2 mask = $50
Find:
Cost of each goggles and mask
Computation:
Assume;
Cost of 1 goggles = a
Cost of 1 mask = b
So,
2a + b = 55.....EQ1
a + 2b = 50.......EQ2
EQ1 x 2
4a + 2b = 110 ......EQ3
EQ3 - EQ2
3a = 60
a = 20
Cost of 1 goggles = $20
a + 2a = 50
20 + 2b = 50
2b = 30
b = 15
Cost of 1 mask = 15
.
First let's just combine the shelves to make it easier. 99 + 99 = 198.
We can simply divide 198 by 11/16 to get the answer. First let's convert 11/16 to a decimal.
11 divided by 16 is 0.6875
So 198 divided by 0.6875 is 288.
288 novels can fit on both the shelves.
