Answer:
Joanne might have utilized a rounded figure at a specific decimal point instead of the precise value. When validating her solution with a rounded figure, the outcome may not align precisely. The values, 12.34 and 12.33, are very similar, allowing Joanne to conclude that she correctly solved the multistep equation.
Step-by-step explanation:
Facts
The rule of 72 provides a rough estimate for how long it takes for an investment to double, solely based on the interest rate. Therefore, the initial deposit does not influence this estimate. Each of the three accounts will take an equal time to double.
As long as all accounts are opened on the same day with identical interest rates and compounding periods, they will double simultaneously, whether calculated via the rule of 72 or through precise timing.
Answer:
The provided radical equation has no solution.
x = 225/16 is not a valid solution.
Step-by-step explanation:
The given equation is
Add 3 to both sides of the equation
Squaring both sides
Divide both sides by 16
Check by substituting the value of x back into the original equation to confirm the extraneous solution.
Since -18 is not equal to 12, thus the value of x fails to satisfy the equation.
Consequently, x = 225/16 is an extraneous solution.
Step-by-step explanation:
75,88,90,96,98,100
minimum = 75
Q1 = 88.....this indicates the start of the box
Q2 (the median) = (90 + 96) / 2 = 186/2 = 93....this signifies the line within the box
Q3 = 98....this indicates the end of the box
maximum = 100
