nvm maybe the last one lol
Answer:
126
Step-by-step explanation:
Total number of birds already observed: 59 + 68 + 12 + 1 = 140
Number of blue jays observed: 59
Fraction of blue jays: 59/140
Number of blue jays expected in 300 birds:
59/140 * 300 = 126
Answer: 126
Answer:
Option D) 5.4%
Step-by-step explanation:
we know that
$75.74 ----> represent the 100%
so
using proportion
Find the percentage that the amount of the customer's water bill increase
Let
x -----> the percentage that increase
$75.74/100%=($79.86-$75.74)/x
$75.74/100%=($4.12)/x
x=100*4.12/75.74
x=5.4%
Although the points do not sit exactly on integer coordinates, we can round their coordinates and say that
Now, remember that the first coordinate represents the number of events, and the second coordinate represents the number of stamps. So, if we want the number of events to be four times the number of stamps, we need a point whose first coordinate is four times the second.
This is the case for point C, because its first coordinate is about 20, and its second coordinate is about 5, and 20 is four times 5.
To determine the slope, you can use the following formula:
(y2-y1)/(x2-x1)
