Answer:
75
Step-by-step explanation:
Average needed to get grade C = 70
Average = Total Amount / No of Items.
No of items = 4
therefore Total needed = 70 x 4 = 280
current total score = 66.75 + 66 + 72.25 = 205
the fourth test minimum score = 280 - 205 = 75
<span>The probability that a person selected at random from the
general population is senior citizen who will get the flu this season is 0.14 x 0.18 = 0.0252</span>
They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
