Answer:
The first choice
Step-by-step explanation:
It says that its decreasing so the slope is negative.
It also starts of with 565 so that's the y intercept
In a box-and-whisker plot the median is shown with a line inside the box.
The box is placed on the top of a numbered line, then you can read the value correspondant to the line that indicates the median.
In this case one of the boxes has a value less than 65 and that is the answer. It is the option c, from the answer choices, which shows a median of 60.
2 because it is the only number smaller than 5
Answer:
If both pens are the same color, it means that they are either black and black or red and red.If without replacement,pr. of first black and second black is
8/11 and 7/10.Also, the pr of the first red and sencond red pen= 3/11 and 2/10.
Therefore pr. of bb or rr
(8/11×7/10)+(3/11×2/10)
56/110+6/110 =31/50
9514 1404 393
Answer:
$7.14
Step-by-step explanation:
Let p, d, q represent the numbers of pennies, dimes, and quarters in the collection, respectively.
p + d + q = 45 . . . . . . . . there are 45 coins in the collection
2p +5 = q . . . . . . . . . . . . 5 more than twice the number of pennies
p + 4 = d . . . . . . . . . . . . . 4 more than the number of pennies
Substituting the last two equations into the first gives ...
p +(p +4) +(2p +5) = 45
4p = 36 . . . . . . . . . . . . . subtract 9
p = 9 . . . . . . . . . . . divide by 4
d = 9 +4 = 13
q = 2(9) +5 = 23
The value of the collection is ...
23(0.25) +13(0.10) +9(0.01) = 5.75 +1.30 +0.09 = 7.14
The coin collection is worth $7.14.
