Answer:
She must make a score of 42 in the final exam to obtain an average of 80.
Step-by-step explanation:
Hi there!
Let x be the score of the final exam, the equation will be as follows (remember that the score of the final counts double):
(82 + 79 + 75 + 2x)/4 = 80
Let´s solve the equation for x multiplying each side of the equation be 4:
82 + 79 +75 + 2x = 320
Substract 82, 79 and 75 to both sides of the equation:
2x = 320 - 82 - 79 -75
2x = 84
x = 84/2
x = 42
She must make a score of 42 in the final exam to obtain an average of 80.
Have a nice day!
It would be eleven plus ten times the 3 roman numeral y=mx+b
1) Sample space of the spinner={Green, Blue, Purple, Yellow, Red}=5
2) Sample space of the cards={Red, Yellow, Blue, Pink }=4
1) P(spinner stops at purple) = 1/5
2) P(pink card selected) = 1/4
1) AND 2) are conditional probabilities:
P(spinner stops at purple ∩ pink card selected ) = (1/5)(1/4) = 1/20 =0.05
