Answer:
To provide a baseline for judging the survival rates of infants who received whole-body cooling
Step-by-step explanation:
In this case, the purpose of the experiment is to see whether reducing body temperature for three days after birth increased the rate of survival without brain damage.
Then, the proposed method (whole-body cooling) has to be contrasted with the baseline, in this case, the "usual care". If we want to know if this proposed method is statistically better, we have to compare with these baseline with random sampling out of the same population.
If it is not compared to nothing or to a new method, it wouldn't be possible to conclude if the method is better or not than the usual care.
The following list gives the number of public libraries in each of 11 cities. 7, 11, 8, 7, 8, 7, 8, 11, 8, 10, 7 Find the modes
AlladinOne [14]
Answer:
The mode are: 7, 8
Step-by-step explanation:
Given
Required
Determine the mode
We start by arranging the given data in ascending order
The ordered data are:
From the above data.
7 has a frequency of 4
8 has a frequency of 4
10 has a frequency of 1
11 has a frequency of 2
The data with the highest frequency is the mode.
We can see that 7 and 8 both have frequencies of 4
<em>Hence, the mode are: 7, 8</em>
Partitive and Quotitive Division. An important distinction in division is between situations that call for a partitive (also called fair share or sharing) model of division, and those that call for a quotitive (also called subtraction or measurement) model of division.
Answer:
37 ft
Step-by-step explanation:
The ladder forms a right triangle as it elan's against the wall of the boat house.
Thus, the length of the ladder can be determined using Pythagorean theorem.
c² = a² + b²
c = length of ladder
a = 35 ft
b = 12 ft
Plug in the values
c² = 35² + 12²
c² = 1,225 + 144
c² = 1,369
c = √1,369
c = 37
Therefore, to reach the roof of the boathouse, the length of the ladder = 37 ft
Answer:
x>-2
Step-by-step explanation:
3(x + 4) > 4 - X
Distribute
3x+12> 4-x
Add x to each side
3x+12+x > 4-x+x
4x+12 > 4
Subtract 12 from each side
4x+12-12>4-12
4x> -8
Divide each side by 4
4x/4 > -8/4
x>-2
