Your answer is 3/75 my friend, Hope i helped!!
Given:
Consider the sides of the triangle are 4x+10, 2x-5 and 18 (in feet).
Perimeter of this triangle is to be no more than 77 feet.
To find:
The inequality and solution of the inequality.
Solution:
Perimeter of a triangle is the sum of all side.
Perimeter of given triangle
Perimeter of this triangle is to be no more than 77 feet. It means perimeter must be less than or equal to 77.
Divide both sides by 6.
Therefore, the required inequality is and the solution is .
The mean is 60; and the standard deviation is 6; since the intervals are in amounts of 6.
Answer:
D. -1.75°C
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:
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:
Assume that the mean reading is 0degrees°C and the standard deviation of the readings is 1.00degrees°C. This means that .
Find the temperature reading that separates the bottom 4% from the others.
The bottom 4% if the 4th percentile.
This is the value of X when Z has a pvalue of 0.04. This is .
The correct answer is:
D. -1.75°C
Answer:
x= 2.5
Step-by-step explanation:
7x-5x = 2x
2x-2 = 3
3 + 2 = 5
2x=5
5/2 = 2.5
