Answer: 
Step-by-step explanation:
You con solve the system of equation with the Substitution method, as following:
- Substitute the second equation into the first equation.
- Solve for x:
- Substitute the value of x obtained above into the second equation to find the value of the variable y. Therefore, you obtain:

The answer is 0.50.
P(4<=X<=8)=P(x=4)+ P(x=5)+ P(x=6)+ P(x=7)+ P(x=8)= 0.05+ 0.15+0.15+0.15 +0 = 0.50
Notice that in 8 the line touches the x axis so it’s corresponding probability is 0.
Answer:Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Sara drove 18 miles per gallon of gas.
72 miles ÷ 4 gallons of gas = 18 miles per gallon of gas
Answer: 15.7 (1 decimal place)
Step-by-step explanation:
The formula for the circumference of a circle is d(diameter) x π(pi).
The diameter of this is 5 so you would do 5xπ=15.7 (1 decimal place)
