(a) Find the linear equation that relates the temperature t and the number of chirps per minute n.
If the equation is linear, then the equation should have the form of t = mn + b
m = (80 - 70) / (168 - 120) = 5/24
t = 5/24n + b
70 = 5/24(120) + b
b = 45
t = 5/24 n + 45
<span>(b) If the crickets are chirping at 138 chirps per minute, estimate the temperature. (Round your answer to the nearest degree.)
</span><span>t = 5/24 n + 45
</span><span>t = 5/24 (138) + 45 = 74 </span>°F
Answer:
1224 cm^3
Step-by-step explanation:
volume = bottom area x height
102x12=1224
Answer: It is (383,000)

Step-by-step explanation:
The mean can be found by adding the two numbers and dividing by 2
let the second number be y
(x + y)/2 = 1/2x + 1
solve for y
multiply each side by 2
x + y = 2(1/2x + 1)
distribute
x + y = x + 2
subtract x on both sides
y = 2
ANSWER: the second number is 2
