With the $10 gift card, Jose can buy at most 8 songs
x(the number of songs) less than or equal to 8
volume of a cone = (1/3)*pi*r^2*h
180 = pi(r^2)h
180/pi(r*2) = h
The answer is on the paper
Answer:
the probability is 0.02 (2%)
Step-by-step explanation:
defining the event S= the message is spam , then the probability is
P(S) = probability that a randomly selected message comes from account #1 * probability that the message is spam given that the message is from account #1 + probability that a randomly selected message comes from account #2 * probability that the message is spam given that the message is from account #2 + probability that a randomly selected message comes from account #3 * probability that the message is spam given that the message is from account #3 = 0.6 * 0.01 + 0.3 * 0.03 + 0.1 * 0.05 = 0.02 (2%)
thus the probability is 0.02 (2%)
Answer:
<h2>x = 4</h2>
Step-by-step explanation:
ΔLMN and ΔPMQ are similar. Therefore thw sides are in proportion:
We have:
LM = 3 + 9 = 12
PM = 9
NM = x + 12
QM = 12
Substitute:
<em>cross multiply</em>
<em>divide both sides by 9</em>
<em>subtract 12 from both sides</em>
