Answer:
Step-by-step explanation:
Given that reading on thermometer is N (0,1)
7% of the thermometers are rejected because they have readings that are too low, but all other thermometers are acceptable
This implies that we have to find out the 7th percentile.
i.e. Z score = -1.475
Hence the temperature for cutoff is below -1.475 degrees.
the temperature reading corresponding to the given information.=-1.475 deg
To find the ratio, you just need to divide the two function and solve it. The calculation would be:
<span>F(t)=Q0(1+r)^t
F(0.11)/F(0.01) = 1.09/1.06
</span>Q0(1+r)^0.11 / Q0(1+r)^0.01 = 1.0291
(1+r)^(0.11-0.01) = <span>1.0291</span>
(1+r)^0.10 = 1.0291
(1+r)^0.10*10 = 1.0283 ^10
(1+r )= 1.3325
r = 0.323
Answer:
C!!!!!
Step-by-step explanation:
because common sense
Mean = (<span>59.29 + 75.79 + 84.40 + 93.21 + 96.54 + 103.59 + 105.79 + 102.18)/8
Mean = 720.79/8
Mean </span> = 90.09875
Mean ≈ 90.10 to 2 decimal places.
Without tax, it would be $127.50. 150*0.15=22.5, and 150-22.5=127.5.
