Answer:
65.827% of the apples have diameter between 3.5 and 4.3 inches.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by
After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X.
So, to find the proportion of apples with diameter between 3.5 and 4.3 inches, we subtract the pvalue of the zscore of X = 4.3 by the pvalue of the zscore of X = 3.5.
The diameters of apples from a certain farm follow normal distribution with mean 4 inches and standard deviation 0.4 inch. So , .
For X = 4.3
Z = 0.75 has a pvalue of 0.77337
For X = 3.5
Z = -1.20 has a pvalue of 0.1151
Subtracting
65.827% of the apples have diameter between 3.5 and 4.3 inches.
Answer:
1.246
Step-by-step explanation:
12+1234 = 1.246
3 decimal places to the left.
Hope it helps. Let me know.
Answer: 4
Step-by-step explanation: so multiply 3 by 10. Then subtract 10 from both sides so you should be left with 20=5r and then you divide both sides by 5 to equal 4
Answer:
9√2
Step-by-step explanation:
a^2+b^2=c^2
a^2+b^2=18^2
a^2+b^2=324
324 ÷ 2 = 162
162 + 162 = 324 (on a 45 45 90 right triangle)
81 and 2 are factors of 162
square root of 162
√162 = √81 * 2 = 9√2
