Zero is neutral since it right between being positive or negative. So always.
Answer:
Dimensions are 20 X 44 feet
Step-by-step explanation:
First we need to build two equations:
For area X times Y = 880
For Perimeter 2x + 2y = 128
Now we need to solve one so we can substitute it into the other:
2x + 2y = 128 becomes
2x = 128 - 2y and then
x = 64 - y We will substitute this into the are equation
(64 - y)y = 880
64y - 
= 880
-
factor out the negative
-(
Factor:
-(y - 20)(y - 44) = 0
y-20 = 0 and y - 44 = 0
y = 20 and y = 44
Plugging these in two both of our formulas works
20 X 44 = 880 for area
2(20) + 2 (44) = 128 for perimeter
Answer:
The 2000 CDC growth charts were developed using a reference population of infants. A pediatrician looks up one of the charts and finds that the 10th percentile for weights of baby boys at 3-1/2 months is 10.9 pounds. This means that *** about 10%*** of the 3-1/2-month-old baby boys in the reference population weigh 10.9 pounds or less, and ***about 90%*** of these baby boys weigh 10.9 pounds or more.
Step-by-step explanation:
Percentiles indicate the position or standing of a value as compared to the general set of values in the same sample space. They indicate the values below which a certain percentage of the data in a data set is found.
The nth percentile of a set of data is the value at which n percent of the data is below it.
Like in this example, the 10th percentile is the value (or score) below which 10% of the observations may be found. Similarly, 90% of the observations are found above the 20th percentile.
Answer: 25x + 75
Step-by-step explanation:
The 25 is the monthly fee, x stands for the number of months and the 75 is the set fee
Answer:
Length SD is greater than length DM.
Step-by-step explanation:
We know that the measure of the opposite angle and a side are related, so by determining which angle is bigger, we can discover which side is longer.
Angle SUD is greater than angle MUD. Angle SUD is the opposite angle to SD, and angle MUD is the opposite angle to DM. Therefore, SD is greater than DM.
