The slant height of a square pyramid is 10 feet.

Step-by-step explanation:

Since we have given that

Surface area of square pyramid = 189 square feet

Length of side of square = 7 feet

Area of base will be given by

$Side\times Side=Side^2=7^2=49\ ft^2$

Let 'l' be the slant height of the square pyramid.

As we know that "Formula for surface area of square pyramid" is given by

$\text{Surface area}=\text{Area of base}+\frac{1}{2}\times \text{Perimeter of square}\times l\\\\189=7^2+\frac{1}{2}\times 4\times 7\times l\\\\189=49+14l\\\\189-49=14l\\\\140=14l\\\\\frac{140}{14}=l\\\\10\ feet=l$

Hence, the slant height of a square pyramid is 10 feet.

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.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
