Answer:
The probability that the actual event is less than 6.5 inches is 0.9999.
Step-by-step explanation:
We are given that you have determined that for this gage you have a standard error of 30%.
For a precipitation event of 5 inches, we have to find the probability that the actual event is less than 6.5 inches.
The z-score probability distribution for the normal distribution is given by;
Z = ~ N(0,1)
where, = mean precipitation event = 5 inches
standard error = = 0.30
Now, the probability that the actual event is less than 6.5 inches is given by = P(X < 6.5 inches)
P(X < 6.5 inches) = P( < ) = P(Z < 5) = 0.9999
The above probability is calculated by looking at the value of x = 5 but in the z table the last value of x is given as 4.40 so we take the area of that value only which has an area of 0.9999.
4 1/10 then 1/4 then -4 then -4 3/4 hope that helps
Answer:
2.92
Step-by-step explanation:
Normal price
4 * 6.98 =27.92
Sale price
2 for 12.50 means 4 at 2* 12.50
2*12.50 = 25
Subtract
27.92-25=2.92
He saved 2.92
The 0 in the number 402 is in the ten place. The number after it is 2. 2 is less than 5.
402 rounded to the nearest ten is 400
The 4 in the number 402 is in the hundreds place. The number after it is 0. 0 is less than 5.
402 rounded to the nearest hundred is 400
