The additional rats will live in this building one year from now is 3.41 x 10^5.
What is the additional number of rats?Standard form is used in expressing large numbers in smaller numbers. In order to write a number in standard form, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
(6.2 x 10^3) x ( 5.5 x 10^1) = 34.10 x 10^4

Which of the following choices is the standard deviation of the sample shown
here?
18, 19, 20, 21, 22
A. 2
B. 12.5
C. 20
D. 2.5
E. square root of 2
Answers
Answer: E. square root of 2
We can write that in shorthand as sqrt(2)
sqrt(2) = 1.41421 approximately
======================================================
Explanation:
Step 1)
Add up the values to get 18+19+20+21+22 = 100
Divide by n = 5, since there are 5 items in the list. So 100/n = 100/5 = 20
The sample mean is xbar = 20
--------------
Step 2)
Subtract the mean from each data value
18 - xbar = 18 - 20 = -219 - xbar = 19 - 20 = -120 - xbar = 20 - 20 = 021 - xbar = 21 - 20 = 122 - xbar = 22 - 20 = 2The results we get are: -2, -1, 0, 1, 2
---------------
Step 3)
Square the results from the previous step
(-2)^2 = 4(-1)^2 = 1(0)^2 = 0(1)^2 = 1(2)^2 = 4The results here are: 4, 1, 0, 1, 4
---------------
Step 4)
Add up those squares from the previous step: 4+1+0+1+4 = 10
Now divide by n = 5 to get 10/n = 10/5 = 2
The result 2 represents the population variance. Applying the square root to the population variance leads to the population standard deviation. So we end up with the final answer of sqrt(2). The answer is choice E.
sqrt(2) = 1.41421 approximately
---------------
Note: if you want the sample standard deviation, then you divide by n-1 = 5-1 = 4, but the other steps are the same as before.

What is the size of the blue angle, and what do we call an angle with these measurements?
Answers
Answers:
The blue angle is 135 degrees
The angle is obtuse
==========================================
Explanation:
Along the inner ring of values, the left arrow points at 135 (the midpoint of 130 and 140). Therefore, the blue angle is 135 degrees. Or you could note that starting at 130, and counting 5 spaces, will get you to 135. You could start at 140, and count down 5 spaces to get to the same spot.
Another way you can get the answer is to note that the blue arrow on the left is pointing at 45 along the top ring of numbers. This adds to 90 to get 90+45 = 135
Either way, you should get to 135 degrees as the angle value.
-------------
The angle is obtuse because the angle is larger than 90 degrees. It's wider or larger than a right angle.

The most Brendan can afford to pay per year in mortgage payments is $10,500, and his credit score is currently 544. According to the following table for a $150,000 mortgage, by how many points would he need to improve his credit score in order to take a mortgage for $150,000? FICO Interest Monthly Score Rate Payment 720-850 700-719 675-699 620-674 560-619 500-559 5.59% 5.71% 6.25% 7.40% 8.53% 9.29% $860 $872 $924 $1039 $1157 $1238 O A. 16 points B. 156 points C. 76 points D. 131 points
Answers
Answer:
B. 156
Step-by-step explanation:
Brendan would need to improve his credit score by 75 points to qualify for a $150,000 mortgage with a monthly payment of $875 or less.
We have,
To determine Brendan's interest rate and monthly payment for a $150,000 mortgage, we need to find which range his FICO score falls in.
From the table, we see that his score of 544 falls in the range of 500-559, which corresponds to an interest rate of 9.29% and a monthly payment of $1238.
Next, we can use the mortgage payment of $10,500 per year to determine the maximum monthly payment Brendan can afford.
i.e
$10,500 per year / 12 months
= $875 per month
Since this amount is less than the monthly payment for the 500-559 FICO score range, Brendan would need to improve his credit score to qualify for a $150,000 mortgage.
To determine how many points he needs to improve, we can look at the next lowest interest rate and payment in the table, which corresponds to a FICO score range of 560-619.
The monthly payment for this range is $1157, which is below Brendan's maximum payment of $875.
So, he needs to improve his credit score to fall into this range.
To determine how many points he needs to improve,
we can subtract the minimum FICO score in the 560-619 range (560) from his current FICO score (544), and then add that difference to the maximum FICO score in the 560-619 range (619).
i.e
(619 - 560) + (560 - 544)
= 59 + 16
= 75
Therefore,
Brendan would need to improve his credit score by 75 points to qualify for a $150,000 mortgage with a monthly payment of $875 or less.

C) Is a parallelogram with the diagonals that intersect but does not form 90 degree
D) Is a parallelogram with diagonals that are congruent and perpendicular
Answers
Answer:
Is a parallelogram with congruent diag............ option is best describing better
The statement which best describes the diagonals of a rhombus is B. Is a parallelogram with diagonals that bisects a pair of opposite angles and the diagonals are perpendicular.
What is Rhombus?A rhombus is a two dimensional shape which consists of four equal sides with opposite side being parallel and opposite angles being equal.
So, rhombus is a parallelogram with all sides being equal.
The diagonals of a rhombus are not of equal length, so they are not congruent.
Also, the two diagonals of a rhombus cuts each other in to two equal halves and the intersecting angle is 90 degrees.
This means that the diagonals of a rhombus are perpendicular bisectors of each other.
Also, the diagonals bisect the pair of opposite angles through which the line passes.
Hence the correct option is B. Is a parallelogram with diagonals that bisects a pair of opposite angles and the diagonals are perpendicular.

Ninas car exponentially depreciate at a rate of 8% per year. If Nina bought the car when it was 6 years old for 12,045 , what was the original price
Answers
Answer: $19,864.60
Step-by-step explanation:
The future value formula could have been used to find the price in the 6th year. As we now know the price, the formula can now be used to find the original price.
Price at 6th year = Original price * ( 1 + rate) ^ number of years
12,045 = Og * ( 1 - 8%) ⁶
12,045 = Og * 0.606355001344
Og = 12,045 / 0.606355001344
Og = $19,864.60
Rate is subtracted because price was reducing.
