Answer:

  • Always do your math with a pencil
  • Line your work up neatly, that way if you do make a mistake you can identify right away where the mistake was made.
  • Normally when you make a mistake you'll notice where the numbers stopped making sense.
  • Check your work by inputting your answer if it doesn't make sense then it is wrong

A flying squirrel's nest is 12 feet high in a tree. From its nest, the flying squirrel glides 13 feet to reach an acorn
siniylev [52]

Answer: the answer should be 5

if you draw a right triangle 12 would be the line that goes up (A) and 13 would be the slanted line (C) so that leaves the bottom line to be C.

hope this helps!

Step-by-step explanation:

A^{2} +B^{2} =C^{2} \\12^{2} +B^{2} =13^{2} \\144+B^{2} =169\\-144             -144\\\sqrt{B^{2} } =\sqrt{25} \\    B=5

A triangle has one side that measures x, and the other two sides each measure 4 inches less than x. The perimeter is 19 inches.
zalisa [80]
Perimeter of a triangle = all 3 sides added together

x + (x - 4) + (x - 4) = 19
3x - 8 = 19
3x = 19 + 8
3x = 27
x = 27/3
x = 9 <==

Kaiden deposited $6200 into a savings account for which interest is compounded weekly at a rate of 2.77%.
scoray [572]
A=p(1+i/m)^mn
A=6,200×(1+0.0277÷52)^(52×8)
A=7,737.59
Interest earned=7737.59-6200=1537.59

Suppose the claim size of an auto collision insurance, X, is uniformly distributed on the interval $1,000 to $10,000. What is th
timurjin [86]

Answer:

35.35%

Step-by-step explanation:

If there were no deductibles, the expected claim payment would be:

E(X) = \frac{10,000 +1,000}{2} \\E(X) =\$5,500

If the collision insurance claim is under $2,000, then the insurer would not pay anything, but if X > $2,000, then the insurer would pay X - $2,000. The new expected value is:

E_2(X)=\frac{2,000-1,000}{10,000-1,000} *0+\frac{10,000-2,000}{10,000-1,000}*\frac{(2,000-2,000)+(10,000-2,000)}{2} \\E_2(X)=\frac{8}{9}*\frac{0+8,000}{2}\\ E_2(X)=\$3,555.56

The percentage reduction on the claim payment is:

P=(1-\frac{E_2(X)}{E(X)})*100 \\P=(1-\frac{3,555.56}{5,500})*100\\P=35.35\%

There was a 35.35% reduction.
