The correct answer is 37 ⁹/16
I did the math, and wrote the expression as: (1 ¼)² + 6². but still getting it wrong.....
also should I always convert a mixed number before using it's exponent???
Answer:
see explanation
Step-by-step explanation:
The sum of the areas of the 2 rooms is
(1 [tex]\frac{1}{4}[/tex] )² + 6² ← change the mixed number to an improper fraction
= ([tex]\frac{5}{4}[/tex] )² + 6²

x is a normally distributed variable with mean μ = 17 and standard deviation σ = 3 find:
a) P(x >21)
b) P(x < 15)
c) P(16 < x < 25)
Answer:
a)0.09176
b)0.22065
c)0.62551
Step-by-step explanation:
a) p(x>21) = p(z> (21-17)/3)=p(z>1.333) = 1-.90824= 0.09176 (subtracting from one because we are looking at the right side of the graph from the Z-table)
b)p(x<15) = p(z< (15-17)/3)=p(z<-.6667) = 0.22065
c)p(16 < x < 25)= (z(16-17)/3 < p < z(25-17)/3)= z(-.333) < p < z(2.667)=.99621 -.37070 = 0.62551
Write an equation for the description . The length of a rectangle is twice its width . The perimeter of the rectangle is 122 feet.
Answer:
122 = 2(2w +w)
Step-by-step explanation:
If we let w represent the width of the rectangle, then 2w is the length of it. The perimeter is twice the sum of length and width.
P = 2(L+W)
122 = 2(2w +w) . . . . an equation for the description

Your laptop died and you need a new one for work NOW! The one you need will cost $500. You do not have the cash in your checking account, so you decide to borrow the money from your savings account. You have $9,000 in your savings account gaining 3% interest per year. If you don't replace the $500 in the savings account, how long will it take before the balance again reaches $9,000?
Answer:
2 years
Step-by-step explanation:
If you have $9000 in the saving account, and you take $500, you are left with:
$9000 - $500 = $8500
in one year you will have 3% more of the 8500 which is:
8500/100*3 = $255
so in one year the number on your savings account is:
8500 + 255 = $8755
and by the next year you will have 3% more of the 8755 which is:
8755/100*3 = $262.65
so in two years the number on your savings account is:
8755 + 262.65 = $9017.65
which is a little bit more than the $9000.
so it will take 2 years until the calance again reaches $9000

Xavier climbs 9 feet up into an apple tree. What integer represents the direction and how far he will climb to get back down to the ground? What does the integer 0 represent in this situation?
Answer:
He started climbing 9 feet up into the tree, so we can assume that the initial position is 9ft above the ground.
Then if he wants to get back into the ground, he must "descend" or climb down 9 ft again.
Then the integer is -9 (because he is climbing down now).
In this case, the 0 represents that he does not move.
So the integer 0 is related to: +0ft or -0ft
This means that he climbs up 0ft or down -0ft, which is the same as not moving at all.

g Researchers studied 208 infants whose brains were temporarily deprived of oxygen due to complications at birth. When researchers detected oxygen deprivation, they randomly assigned babies to either usual care or to a whole-body cooling group. The goal was to see whether reducing body temperature for three days after birth increased the rate of survival without brain damage. What is the response variable
Answer:
The rate of survival without brain damage
Step-by-step explanation:
The response variable (or dependent variable) is the variable that is measured and which depends on other variables. In this experiment, the researchers are investigating the impact of reducing body temperature on rate of survival without brain damage. The variable that they were 'measuring' was the rate of survival without brain damage, which depended on the variable of reducing body temperature, therefore the response variable here is the 'rate of survival without brain damage.'

A.28,700
B. 0.000287
C. 2,870
D. 287,000
The general form of the number is 28,700. The correct option is A.
What is a standard form?Any value between 1.0 and 10.0 that can be expressed as a decimal number and multiplied by a power of 10 is referred to as being in standard form.
The given number is 2.87 x 10⁴. The general form of the number can be written as:-
2.87 x 10⁴ = 2.87 x 10000
2.87 x 10⁴ = 28700
Multiply 2.87 by 10000 we will get the general form 28700 for the number.
Therefore, the general form of the number is 28,700. The correct option is A.
