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.'
Hope this helped!
It takes Mrs. Rice 4 hours to drive the 240 miles to visit her sister in Plano.
Calculate the rate to the nearest whole mile per hour for Mrs. Rice's drive.
Given:
Time = 4 hours
Distance = 240 miles
To find:
The speed or the rate mile per hour for Mrs. Rice's drive.
Solution:
We know that,
[tex]Speed =\dfrac{Distance}{Time}[/tex]
On substituting the given values, we get
[tex]Speed =\dfrac{240}{4}[/tex]
[tex]Speed =60[/tex]
Therefore, the speed or rate is 60 mile per hour for Mrs. Rice's drive.
After 8 points are added to each score in a sample, the mean is found to be M= 40. What was the value for the original mean
Answer:
The value for the original mean = 32
Step-by-step explanation:
Here, we want to calculate the original value of the mean.
Let the number of samples be n
Mathematically;
mean = Total value/n
Now, we added 8 to each of values; total value added = 8 * n = 8n
Now, for the new mean of 40; we have
(Total value + 8n)/n = 40
Total value + 8n = 40n
Total value = 40n -8n
Total value = 32n
kindly recall from the beginning of the solution;
mean = Total value/n
mean = 32n/n
mean = 32
So the original value of the mean is 32

write the product of a number and 21 as an algebraic expression
Answer:
21n=
n-number and since its a number (n) and 21 you would put 21n
Answer:
[tex]\boxed {\tt 21n}[/tex]
Step-by-step explanation:
We want to write the product of a number and 21 as an algebraic expression. Let's define "a number" as the variable n.
We know that "product" means multiplication. The product of a number, n, and 21 is equal to multiplying n and 21.
[tex]n*21[/tex]
21 and n can be flipped due to the commutative property of multiplication.
[tex]21*n[/tex]
[tex]21n[/tex]
The product of a number and 21 is 21n.

A serving of small frozen casserole is 1/3 of the pan. If you eat 1/4 of the pan, what fraction of a serving have you eaten
Answer:
If the portion of frozen casserole occupies 1/3 of the pan, it can be affirmed that it occupies 0.333 of it. Thus, if someone eats 1/4 of the pan, it could be stated that they are eating 0.25 of it.
Therefore, to determine the fraction of the portion that has been eaten, the following calculation must be performed:
33 = 100
25 = X
(25 x 100) / 33 = X
2500/33 = X
75.75 = X
25/33 = X
Therefore, the fraction of the serving that was eaten is 25/33, or 76% of the serving.

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.
A rectangular table is two times as long as it is wide. If the area is 50 ft2, find the length and the width of the table.
Answer:
length = 10ft
breadth = 5ft
Step-by-step explanation:
Given,
Let breadth be x.
According to the question,
length = 2x
Area = 50ft^2
we know that,
Area of rectangle ( A) = l × b
or, x × 2x = 50 ft^2
or, 2x^2 = 50ft^2
or, x^2 = 50ft^2/2
or, x^2 = 25ft^2
or, x = 5 ft
Now,
2x = 2×5ft =10ft
Therefore, length is 10ft and breadth is 5ft.

13/15 × 1 1/39 multiplying/dividing fractions help me
Before multiplying two fractions together, always try to cross-cancel.
So in this problem, the 13 and 39 cross-cancel to 1 and 3.
So we have 1/15 × 11/3 which is 11/45.
Remember, multiply across the numerators and denominators.
6. Identify the recursive formula for the sequence 3, –15, 75, –375, . . .
Answer:
first option
Step-by-step explanation:
There is a common ratio r between consecutive terms in the sequence, that is
r = - 15 ÷ 3 = 75 ÷ - 15 = - 375 ÷ 75 = - 5
The recursive formula allows a term in the sequence to be found by multiplying the previous term by r , thus
f(n) = - 5f(n - 1) if n > 1
with f(1) = 3 ← first term
Answer:
D . f(n)=f(1)=3
f(n)= -5f(n-1)if n >1

A spinner with 6 equally sized slices is shown below. (2 slices are yellow, 1 is blue, and 3 are red.) The dial is spun and stops on a slice at random. What is the probability that the dial stops on a yellow slice?
Answer:
1/3
Step-by-step explanation:
We have 6 slices
2 are yellow
P ( yellow) = number of yellow / total
= 2/6
= 1/3
Answer:. 1/3 probability that it stops on yellow.
Step-by-step explanation:
There are 6 possible outcomes. 2 are the incidents that you are looking for.
Make a ratio 2:6 or a fraction 2/6
Then simplify or reduce the fraction. 2/6 = 1/3
what is −4(−5x+2)−3x−5= -30
Answer:
x = -1
Step-by-step explanation:
Step 1: Write equation
-4(-5x + 2) - 3x - 5 = -30
Step 2: Solve for x
Distribute -4: 20x - 8 - 3x - 5 = -30
Combine like terms: 17x - 13 = -30
Add 13 on both sides: 17x = -17
Divide both sides by 17: x = -1
Answer:
x = -1
Step-by-step explanation:
invere operation
−4(−5x+2)−3x−5= -30
20x - 8 -3x - 5 = -30
17x -13 = -30
17x = -17
x = -1

When using Newton's Method to find the root of a linear function f(x) = ax + b, a 70, how many iterations of the method are required to find the root at r = R?1 4 2 There is no fixed number. It depends on the intial guess xo.
Answer:
It depends on the initial guess Xo
Step-by-step explanation:
The number of iterations required to find the root at r = R depends on the initial guess Xo, this is because when using Newton's method for finding roots, you will need to pick an initial guess and this will be followed by an iterative process which would converge to a solution. The number of roots before the converging will take place depends on the initial guess Xo made

. What is the total number of digits
printed, if a book containing 150
pages is to be numbered from 1 to
150?
Solution :-
Total number of pages in the book = 150
Total number of one digit numbers = From 1 to 9
= 1*9
9 digits
Total number of two digit numbers = From 10 to 99
= 2*90
= 180 digits
Total number of three digit numbers = From 100 to 150
= 3*51
= 153 digits
Total number of digits printed in the book containing 150 pages
= Total number of one digit numbers + Total number of two digit numbers +
Total number of two digit numbers
= 9 + 180 + 153
= 342 Digits
Hence, total 342 digits are printed in the book which has 150 pages.

Answer:
Angle 1: 34°
Angle 2: 146°
Angle 3: 146°
Angle 4: 34°
Angle 5: 34°
Angle 6: 146°
Angle 7: 146°
Angle 8: 34°
Step-by-step explanation:
Angle 1: because angle 1 and 5 are corresponding, we know that angle 1 is 34°.
Angle 2: because a line is 180°, we can set angle 1 and 2 equal to 180° ( 34+x+15=180) which when solved, x = 131. but you need to plug it back into the equation of angle 2 to find out how many degrees it is. ( 131+15=146 ) So angle 2 is 146°
Angle 3: angles 2 and 3 are vertical angles, so angle 3 is 146°
Angle 4: angles 1 and 4 are vertical, so angle 4 is 146°
Angle 5: is given
Angle 6: angles 2 and 6 are corresponding so they are equal, angle 6 is 146°
Angle 7: angles 6 and 7 are vertical so angle 7 is 146°
Angle 8: angles 5 and 8 are vertical of each other so they are equal, angle 8 is 34°
