Answer:
For 1,000 bricks, the amount charged will be the same
Step-by-step explanation:
Let the number of bricks for which they charge the same amount be $x
Thus;
The total cost from the first company will
be;
250 + 0.2(x) = 250 + 0.2x
The second will charge;
400 + 0.05(x) = 400 + 0.05x
Since the amount charged will be equal at x bricks, we need to equate both;
400 + 0.05x = 250 + 0.2x
400-250 = 0.2x-0.05x
150 = 0.15x
x = 150/0.15
x = 1,000
The answer would be $25.22 the way to do this would be to divide 7.76 by 4 and then you would multiply that answer by 13 so it would be the 4th answer
Answer:
Less than
Step-by-step explanation:
Although it wasn't an option, it is less than. In order to accurately compare then, you have to get the least common denominator. Using the least common multiple (2), you multiply 5/8 by 2 and end up with 10/16. Now 10 is less than 11, so the option is neither of those. 5/8 is less than 11/16.
Answer:
x = 5
Step-by-step explanation:
x + 14 = 19
x + 14 - 14 = 19 - 14
x = 5
Answer:
The probability that a person with the marker develops cancer is 0.0725.
Step-by-step explanation:
Let's denote the events as follows:
<em>A</em> = a person has cancer
<em>B</em> = a person carries the marker.
<u>Given:</u>
P (A) = 0.03
P (B) = 0.12
P (B|A) = 0.29
The conditional probability of an event <em>X</em> provided that another event <em>Y</em> has already occurred is:

Use the conditional probability formula to compute the probability that a person with the marker develops cancer.

Thus, the probability that a person with the marker develops cancer is 0.0725.
