C is the only one that makes sense
Answer:
x = 7 and y = -2
Given:
x = 5y + 17 _____first equation
2x + 3y = 8 ____second equation
Steps:
2x + 3y = 8
<em>plug in x = 5y + 17 into second equation</em>
<em></em>
2(5y + 17)+3y = 8 [ open the brackets ]
10y + 34 + 3y = 8
10y + 3y = 8 - 34 [ collect and group terms ]
13y = -26 [ divide both sides by 13 ]
y = -2 [ final answer ]
solve for x:
x = 5y + 17
x = 5(-2) + 17
x = 7
The third decimal digit from the decimal point is thethousandths<span> digit. Read the whole set of three decimal digits as a number, and say “</span>thousandths<span>.” 0.825 has </span>8<span> tenths, 2 </span>hundredths<span>, and </span>5 thousandths<span>. While 0.825 is the sum of </span>8<span>/10, 2/100, and </span>5<span>/1000, it is also 825/1000 (825 </span>thousandths<span>).</span>
Using conditional probability, the equation that implies that a and b are independent events is P(B|A) = P(B).
<h3>What is Conditional Probability?</h3>
Conditional probability is the probability of one event happening, considering a previous event. The formula is:
In which:
- P(B|A) is the probability of event B happening, given that A happened.
- is the probability of both A and B happening.
- P(A) is the probability of A happening.
If A and B are independent events, we have that:
.
Then, at the conditional formula:
