Answer:
Step-by-step explanation:
Let x be the normal body temperature
X is N(99, sigma)
Sample mean x bar = 98.2 and s = 0.63
Margin of error = Z critical * 0.63 = 1.95 *0.63 = 1.2285
It is safe since 1.5 <1.96 critical value of z at 95%
Answer:
4/5 or 0.8
Step-by-step explanation:
Rise/Run
Y2-y1/x2-x1
Answer:
A & A
Step-by-step explanation:
18)the graph of the function is stretched by half, thus it compresses toward the x axis. while the +4 in the root is moved 4 to left.
19) set equations equal to each other and solve for x and y one at a time
23/100×$640=147.2 is the answer
Answer:
