Answer:
38.40% probability that it would take between 2.5 and 3.5 hours to construct a soapbox derby car.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. 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, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Find the probability that it would take between 2.5 and 3.5 hours to construct a soapbox derby car.
This is the pvalue of Z when X = 3.5 subtracted by the pvalue of Z when X = 2.5
X = 3.5
has a pvalue of 0.6915
X = 2.5
has a pvalue of 0.3075
0.6915 - 0.3075 = 0.3840
38.40% probability that it would take between 2.5 and 3.5 hours to construct a soapbox derby car.
Remember that (a-b)(a+b)=a²-b²
and (imaginary number)²=real
so if we have a+bi, then a-bi is the conguate because (a+bi)(a-bi)=a²+b²
if the complex number is a+bi the conjucate is a-bi
You should find the area under the curve. Which will give you multiple shapes. That are 3 triangles and one rectangle. Then use the Rule of the area of the triangle which is 1/2 × base × height then lastly. When you find the area for each shape you then find the sum of all the distance to give you the full area under the curve.
