Simon must maintain an average grade of 80% or better in his math class to be eligible to play sports. His math grades so far are: 80%, 84%, 76%, 77%. At this point, his grades make him ineligible to play. What is the lowest he score on his next grade to bring his average score up to an 80%. Part A: Write an inequality to represent the average of the five grades as greater than or equal to 80%. Part B: Use the inequality from Part A to prove what his lowest score could be on the 5th test.

(a)

(b)83%

Step-by-step explanation:

His math grades so far are: 80%, 84%, 76%, 77%.

Let the lowest score required to bring his average score up to an 80% =x

(A)Average of the five scores

=

=

If the average of the five grades as greater than or equal to 80%.

Then:

(b) To find what his lowest score should be, we solve the inequality derived in part A.

Cross Multiplying

The lowest score he requires is 83%.

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
