Answer:
C
Step-by-step explanation:
We need to use the distributive property to expand this.
The property is:
a(b+c) = ab + ac
So, the part " -3(2b+1) " will becomes:
-3(2b+1) = (-3)(2b) + (-3)(1) = -6b - 3
So, the problem becomes:
-2b -3(2b+1) = -2b -6b -3
Now, we add like terms:
-2b - 6b - 3
(-2-6)b - 3
-8b - 3
This is the correct answer, answer choice C
Use the next formula to find the margin or error:
z is the critical value (For a 95% confidence level the z-score is 1.95998)
σ is the standard deviation
n is the sample size
<h2>Then the margin of error is: 6.6639</h2>
Answer:
y = x.
Step-by-step explanation:
From the graph we see that the line passes through the origin (0, 0) and the point (8,8), so the slope is (8-0) / (8-0) = 1.
The y intercept is at (0.0).
y =- mx + c is the slope intercept form so m = 1 and c = 0 and the answer is
y = 1x + 0
y = x.
The square root of 9 is 3
The total cost of transactions for Belinda is $899.
<u>Solution:</u>
Given that, Belinda used an online broker who charged a flat fee of $8.99 per transaction.
Belinda bought 100 shares of of BMN Inc, stock at \$12.85 a share,
We have to find what was the total cost of the transaction?
Now, we know that, transaction cost per transaction = $8.99
And, number of transactions = 100 shares.
Then, total cost of transaction = cost per transaction x number of transactions = 100 x 8.99 = $899
Hence, the total cost of transactions is $899
