Answer:
The length in centimeters of the Panama Canal on Ana’s map is 16.4 cm
Step-by-step explanation:
we are given that
Ana drew a map of the Panama Canal. In the scale Ana used for the map, 4 centimeters represents 20 kilometers
so,
20 km =4 cm
now, we can find 1 km
we can divide both sides by 20
now, we can multiply both sides by 82
now, we can simplify it
we get
82 km =16.4 cm
So,
The length in centimeters of the Panama Canal on Ana’s map is 16.4 cm
Given:
value of the test statistic is t20 = 1.95
corresponding p-value of 0.0653 at the 5% significance level
No, I can't conclude that the correlation coefficient differs from zero because the p-value, which is 0.0653 exceeds 0.05.
The correlation coefficient differs from zero when the p-value is less than 0.05.
Answer:
13.68 miles per gallon
Step-by-step explanation:
Varies inversely
mpg * speed = constant
A vehicle gets 16 miles per gallon at 53 mph
53 * 16 = 848
How many miles per gallon will it get at 62 mph?
mpg * 62 = 848
Divide both sides by 62
mpg = 848/62 = 13.6774193548
rounded
13.68 mpg
4x+6=6x-12
-4x -4x
+12 +12
18=2x
9=x
