Answer:
New Digit = 315,864
Step-by-step explanation:
Given:
Digit - 135,864
Value of digit 3 = 30,000
Find:
New Digit, Value of 3 is 10 times greater
Computation:
Value of 3 is 10 times greater = (30,000) = 300,000
New Digit = 315,864
Answer:
a) The expected number of questions that are answered correctly by both A and B = 11 (7 + 4).
b) The Variance of the number of questions that are answered correctly by either A or B = 2.25.
Step-by-step explanation:
Number of questions in the examination = 10
Probability of A's answer being correct = 0.7
Probability of B's answer being correct = 0.4
The expected number of questions that are answered correctly by both A and B:
Probability of Expected
Correct Answer Value Variance
A 0.7 7 (0.7 * 10) 2.25
B 0.4 4 (0.4 * 10) 2.25
Total expected value = 11
Mean = 5.5 2.25
In Step 1, she used the Distributive Property incorrectly. She should have distributed the 3 to the 2. The equation should have been
3x + 6 + 1 = 24.
Answer:
Landry will have $5039.58
Step-by-step explanation:
compound interest formula: amount = p(1 + \frac{r}{n})^{nt}
p= principal ($2,300)
r= interest rate as a decimal (4% = 0.04)
n= number of times the principal is compounded per year (annually = once per year so 1 time per year)
t= time in years (20 years)
new equation: amount = 2300(1+\frac{0.04}{1} )^{1*20}
That equation equals $2,739.58 which you add to the principal.
$2,739.58 + $2,300 = $5039.58
hope this helps :) the equations aren't showing up right :(
