4x (2x-3) (x+2) would be your answer.
71% bec u would do 35-10 and get 25 then do 25\35 and get 71%
Answer:
P(X > 0.3) = 0.3897
Step-by-step explanation:
Normal probability distribution:
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.
Central limit theorem:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , the sample means with size n of at least 30 can be approximated to a normal distribution with mean and standard deviation
Applying the central limit theorem:
P( > 0.3)
This is 1 subtracted by the pvalue of Z when X = 0.3. So
By the Central Limit Theorem
has a pvalue of 0.6103
1 - 0.6103 = 0.3897
So
P(X > 0.3) = 0.3897
Answer:
48 square units
Step-by-step explanation:
Given that the sides of a triangle are 10,10 and 16.
The triangle with two equal is called and isosceles triangle.
The area of an isosceles triangle is = (b*h)/2
We have to calculate height now,
An isosceles triangle form two right triangles, each with hypothenous equal to 10.
Therfore, the base of one right triangle is 16/2 = 8
Using hypotheneous and base, we can calculate the height of the triangle
=> (10)^2 = h^2 + 8^2
=> 100 = h^2 + 64
=> h^2 = 100 - 64
=> h^2 = 36
=> sqrt(h^2) = sqrt(36)
=> h = 6
So the area is: (6*16)/2 = 48 square units
I think the answer is like a little over 6 minutes
