Answer:
42
Step-by-step explanation:
to find the sum, you need to add, so in this case, we're finding the sum of 8 and 6, so it would be
8+6=14
now, we have to times 14 by 3
14×3=42
so the answer is 42
Answer:
Between 21 years and 75 years
Step-by-step explanation:
Given that a real estate company is interested in the ages of home buyers. They examined the ages of thousands of home buyers and found that the mean age was 48 years old, with a standard deviation of 9 years.
X the ages of home buyers is N(48, 9)
a) 
Hence using Cheby chev inequality
b) 
c) Using normal distribution we have
d) z value is 2.97
Hence x lies between
Between 21 years and 75 years
Answer: 13/7
Step-by-step explanation: So you add a one on the bottom of the 5 then multiply it. 5X3=13 and 1X7= 7 then you get 13/7.
Answer:
a = 32
Step-by-step explanation:
This is a right triangle and the square value of hypotenuse is equal to sum of square value of other two side lengths
68^2 = 60^2 + a^2
4624 = 3600 + a^2
4624 - 3600 = a^2
1024 = a^2 find the root for both sides
32 = a
Answer:
y = 1/3x -2
Step-by-step explanation:
the equation for slope intercept form is y= mx + b.
m is the slope and b is where the line crosses the y-axis which is called the y-intercept.
to find the y-intercept plug in a coordinate on the line (6,0)
0 = 1/3(6) + b
then solve for b by first multiplying 1/3 by 6
0 = 2 + b
subtract 2 from both sides
-2 = b
and then you can plug b into the equation
y = 1/3x - 2
