If two chords of a circle are congruent, then their intercepted arcs are congruent
7x-39 = 87
7x = 87 + 39
7x = 126
x = 126/7
x = 18
Answer:
The probability of getting someone who is age 18-22 or does not smoke is 0.854 ....
Step-by-step explanation:
Through the given statements we have to find the probability of getting someone who is age 18-22 or does not smoke.
Age 18-22 has 177 people. 48 of whom smoke.
People who does not smoke =(177-48) + (146-31) +(81-28)
People who does not smoke=129+115+53 = 297
People with age (18-22) who does not smoke = 129
P(18-22 or does not smoke) = (177+297-129)/(177+146+81)
P(18-22 or does not smoke) = 345/404
P(18-22 or does not smoke) = 0.854
Thus the probability of getting someone who is age 18-22 or does not smoke is 0.854 ....
If the original price tag of the video game is $128, to get its discounted price at 15%, that means what Leiff paid for was (100-15) = 85% of the original price.
So, the price of the video game then becomes
(0.85 x 128) = $108.80.
Since Leiff has to pay an additional 5.3% of the new price, that's (100 + 5.3) = 105.3% of the new price which is
(1.053 x 108.8) = $114.57
Adding the shipping fee for the videogame,
114.57 + 4.75 = $119.32
Thus, the total price is <span>$119.32</span>
Answer:
all real numbers except 2 and 4
Step-by-step explanation:
The exceptions in the domain are the values that make the denominator zero. For a denominator of x² -6x +8 = (x -4)(x -2), the values that make it zero are x=4 and x=2.
The domain is all real numbers except 2 and 4.
