Answer:
Part A). 25 feet
Part B). 16.25 feet
Step-by-step explanation:
Part A). By applying Pythagoras theorem in ΔABC,
AC² = AB² + BC²
AC² = (24)² + 7²
AC² = 576 + 49
AC = √625
= 25 feet
Part B). By applying Pythagoras theorem in ΔABC,
AC² = AB² + BC²
(25)² = (19)² + x²
625 = 361 + x²
x² = 625 - 361
x = √264
x = 16.25 feet
16 for the first one
25.2 for the second one
48 times every 90 secnds for the 3rd one
12 for the 4th one
18 for the 5th one
.57 for the last one
The correlation calculation only works well for relationships that follow a straight line.
Therefore in this case, the trend is not linear.So there is no correlation.
c. There is almost no relationship between x and y.<span />
Answer:
2.5%
Step-by-step explanation:
% = (faulty batteries / total batteries) x 100
= (3/120) x 100
= 0.025 x 100
= 2.5
