Step-by-step explanation:
-1/2 - 4
= -9/2 or -4.5
Given:
length of rectangle = 4 units
Height of rectangle = 2x + 6 units
To find:
Not given, so I will find area and perimeter of rectangle. If you want the length of the diagonal of the rectangle, please ask me.
Steps:
Perimeter of rectangle = 2(L + B)
= 2( 4 + 2x + 6 )
= 2( 10 + 2x )
= 2 * 10 + 2 * 2x
= 20 + 4x units
Area of rectangle = L * B
= 4 * (2x + 6)
= 4 * 2x + 4 * 6
= 8x + 24 units²
Therefore, the perimeter of the rectangle is 20 + 4x units, and the area of the rectangle is 8x + 24 units².

Answer:
The probability that a student pick from this group at random either has blue or brown eyes is
P = 40/65 = 0.6154
P = 61.54%
Corrected question;
In a group of 65 students 10 have brown eyes and 30 have blue eyes. Find the Probability that a student pick from this group at random either has blue or brown eyes
Step-by-step explanation:
Given;
Total number of students = 65
Number of students with either blue or brown eyes;
= 10+30 = 40
The probability that a student pick from this group at random either has blue or brown eyes is
P = 40/65 = 0.6154
P = 61.54%
Answer:
The probability that in any given year there will be fewer than 10 percent erroneous returns is P(x≤0.1)=0.264.
Step-by-step explanation:
For a beta distribution with α = 2 and β = 9, we need to use a calculator to compute the probabilities.
The probability that in any given year there will be fewer than 10 percent erroneous returns is P(x≤0.1)=0.264.
