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 answer is y=x+2
Step-by-step explanation:
The row of numbers beside the x each are represented by x in the equation. The equation must be true for all numbers. You must look at each number and find the pattern.
1+2= 3
2+2=4
3+2=5
each x value fits the pattern of being equal to the y value below it when adding two.

Step-by-step explanation:
Answer:
a) 
b) 86.5 years
Step-by-step explanation:
All values are rounded to 2 decimal places
a) We can find line by using y =mx+b
Therefore the line of best fit is 
b) We can do this by using the formula of the best fit line to estimate the life expectancy of someone born in 2005
Therefore the estimated life expectancy of someone born in 2005 is 86.5 years
PS. Please give brainliest answer this was a lot of working out
Answer:
15
Step-by-step explanation:
This is a Pythagorean theorem problem. You must do a^2+b^2=c^2
9^2+12^2=225
then, we must find the square root of 225 which is 15.
