Answer: The man has 10$.
Step-by-step explanation:
We start with the number 60. He sells the goat for 70 dollars, and makes a 10 dollar profit. Then, he buys it for 80$, leaving him with 0. But then he sells it for 90$, making another profit of 10$.
Answer:
About 300 of every 1,000 cars assembled should have one or more defects
Step-by-step explanation:
From the sample of 100 cars, we can estimate the total number of defective cars, using a rule of three.
In this question:
For each 100 cars, 30 defective.
How many defective for 1000?
100 cars - 30 defective
1000 cars - x defective
Simplifying by 100
About 300 of every 1,000 cars assembled should have one or more defects
Answer:
b = - 21
Step-by-step explanation:
calculate m using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 4, - 5) and (x₂, y₂ ) = (- 6, 3)
m = 
= 
= - 4
y = - 4x + b ← is the partial equation
to find b substitute either of the 2 given points into the partial equation
using (- 4, - 5 ), then
- 5 = 16 + b ⇒ b = - 5 - 16 = - 21
The number of integers from 100 to 900 that can be written in base ten without using the digit 7 is 648.
From 100 to 999, all integers are three (3) digit numbers and available digits are (0, 1, 2, 3, 4, 5, 6, 7, 8, 9).
It implies that the total number of digits is 9. The next thing to do will be to arrange the 9 digits in three (3) places in such a way that repetition is allowed.
In the first place;
- the number of ways the number can be positioned since it can't be zero and seven = 8.
Hence, the first chance is 8 out of 10 chance.
In the second and third place;
∴
The number of integers from 100 to 900 that can be written in base ten without using the digit 7 is:
= 8 × 9 × 9
= 648
Therefore, the number of integers from 100 to 900 that can be written in base ten without using the digit 7 is 648.

0.083 as a percentage would be 8.3% with a horizontal bar on top of the three. This is to indicate that it is repeating. To find percentage when you have a decimal, multiply a decimal by 100. If it is a fraction, divide the numerator by the denominator and you get a decimal. Then multiply it by 100 to get the percent.
