Answer:
-1.
Step-by-step explanation:
The graph decreases by 5 for every year, so it has a perfect linear dependence of |1|. The graph is also negative, so the correlation coefficient has to be negative.
Here we're dividing a fraction (5/8) by another fraction. We could obtain the same result by inverting the divisor (2/5) and then multiplying (5/8) by (5/2).
The product is 25/16.
Thus, 2/5 divides into 5/8 25/16 times, or 1 9/16 times.
Answer:
x = 5
Step-by-step explanation:
According to the Pythagorean theorem a²+b²=c²
In this case its:
x² + 12² = 13²
169 - 144 = x²
x² = 25
x = 5
40.75 - 7.05= 33.7
33.7 / 2 = 16.85
16.85 ft. should be on each side of the 7.05 ft. bench
