Answer:
Step-by-step explanation:
x-2(4x-3)=30
x-8x+6=30
-7x=30-6
-7x=24
x=-24/7 maybe it is a mistake in the statement of the problem
Answer:
You can’t solve but you can simplify to
3x^3-10x+1
Step-by-step explanation:
Answer:
first blank: c(x) = 45x + 14
second blank: 7
Step-by-step explanation:
explanation for second blank:
set up the equation equal to 329:
45x + 14 = 329
subtract 14 from both sides:
45x = 315
divide by 45 to leave x alone:
x = 7

P(J / R) = P (J and R) / P(R)
<span>0.8 = P (J and R) / 0.6 </span>
<span>P (J and R) = 0.6 * 0.8 = 0.48 [Probability John practicing and it is raining] </span>
<span>P(J / NR) = P (J and NR) / P(NR) </span>
<span>0.4 = P (J and NR) / (1 - 0.6) = P (J and NR) / 0.4 </span>
<span>P (J and NR) = 0.4 * 0.4 = 0.16 [Probability John practicing and it is not raining] </span>
<span>Hence; </span>
<span>Propability of John practicing regardless of weather condition is </span>
<span>P(John Practicing) = 0.48 + 0.16 = 0.64</span>
