Answer:
The 95 percent confidence interval for the mean of the population from which the study subjects may be presumed to have been drawn is (19.1269, 32.6730).
Step-by-step explanation:

9 25 625
10 20 400
∑ 259 ∑ 7515
Mean= X`= ∑x/n= 259/10= 25.9
Variance = s²= 1/n-1[∑X²- (∑x)²/n]
= 1/0[7515- (259)²/10]= 1/9[7515- 6708.1]
= 806.9/9=89.655= 89.66
Standard Deviation= √89.655= 9.4687
Hence
The value of t with significance level alpha= 0.05 and 9 degrees of freedom is t(0.025,9)= 2.262
The 95 % Confidence interval is given by
x`±t(∝,n-1) s/√n
So Putting the values
25.9± 2.262( 9.4687/√10)
= 25.9 ±2.262 (2.9943)
= 25.9 ± 6.7730
= 25.9 +6.7730=32.6730
25.9 -6.7730= 19.1269
= 19.1269, 32.6730
The 95 percent confidence interval for the mean of the population from which the study subjects may be presumed to have been drawn is (19.1269, 32.6730).
Determine how many terms should be used to estimate the sum of the entire series with an error of less than 0.001.
Answer: 9
Step-by-step explanation:
Tₙ ₊ ₁ < 0.001
1 / ( (n+1) 3 +1 ) < 0.001
(n+1)3 + 1 > 1000
(n+1)3 > 999
n+1 > 9.9966
n = 8.9966 => n = 9
I should take n = 9 to be sure that the error is less than 0.001.

A tree is 4 1/2 feet tall. It is expected to grow 1 3/4 feet per year. At this growth rate, how many years will it take for the tree to have a height greater then 40 feet?
Answer:
21 years
Step-by-step explanation:
Given
[tex]Initial\ Height = 4\frac{1}{2}[/tex]
[tex]Final\ Height = 40[/tex]
[tex]Difference = 1\frac{3}{4}[/tex]
Required
Determine the years it'll take to grow to the final height
This question depicts arithmetic progression and will be solved using
[tex]T_n = a + (n - 1)d[/tex]
Where
[tex]T_n = 40[/tex]
[tex]a = 4\frac{1}{2}[/tex]
[tex]d = 1\frac{3}{4}[/tex]
Substitute these values in the given formula;
[tex]40 = 4\frac{1}{2} + (n - 1)1\frac{3}{4}[/tex]
Convert all fractions to decimal
[tex]40 = 4.5 + (n - 1) * 1.75[/tex]
Open Brackets
[tex]40 = 4.5 + 1.75n - 1.75[/tex]
Collect Like Terms
[tex]1.75n = 40 - 4.5 + 1.75[/tex]
[tex]1.75n = 37.25[/tex]
Divide both sides by 1.75
[tex]n = \frac{37.25}{1.75}[/tex]
[tex]n = 21.2857142857[/tex]
[tex]n = 21[/tex] (Approximated)
The number of years it will take for the tree to have a height greater than 40 feet is 23 years
Given:
Height of the tree = 4 1/2 feet
Growth rate per year = 1 3/4 feet
Expected growth rate = 40 feet
Expected Number of years = y
The inequality:
4 1/2 + 1 3/4y > 40
Subtract 4 1/2 from both sides
1 3/4y > 40 - 4 1/2
7/4y > 40 - 9/2
7/4y > (80-9)/ 2
7/4y > 79/2
divide both sides by 7/4
y > 79/2 ÷ 7/4
y > 79/2 × 4/7
y > (79×4) ) (2×7)
y > (316) / 14
y > 22.57142857142857
Approximately,
y > 23 years
Therefore, number of years it will take for the tree to have a height greater than 40 feet is 23 years

What is subtraction on number line?Subtraction on a number line helps to subtract smaller numbers very easily. While subtracting numbers on a number line, we need to jump (move) towards the left-hand side of a number line. We always start with the minuend and move towards the left according to the number given as the subtrahend. 'Minuend' is the number from which we subtract and 'subtrahend' is the number which is subtracted.
According to the given question.
We have an expression -8 -3
For evaluating the given expression on number line Michael have to follow some following steps:
Step1: Michael have to locate -8 on the number line.
Step2: Michael have to move towards the left hand side of the number line according to the number given in the subtrahend. In the given expression the subtrahend is 3, so we will move 3 units left. And at -11 he have to stop.
So, -11 will be the answer of the even expression.
Hence, the step which complete evaluate Michael expression is "Michael could rewrite the expression as negative 8 + negative 3 and move 3 spaces to the left".

What is the center of the circle that has a diameter whose endpoints are (9, 7) and (-3, -5)?
Answer:
(3, 1)
Step-by-step explanation:
Midpoint of the diameter is the center
Since endpoints are (9, 7) and (-3, -5)
Midpoint will be:
((9 - 3)/2, (7-5)/2) = (3, 1)So the center is (3, 1)
Answer:
(3, 1)
Step-by-step explanation:
Midpoint of the diameter is the center
Since endpoints are (9, 7) and (-3, -5)
Midpoint will be:
((9 - 3)/2, (7-5)/2) = (3, 1)
or 3/1, 2/2 = (3,1)
So the center is (3, 1)

A study was conducted on the relationship between speeds of cars and gas mileage. The correlation coefficient was 0.45. Later, the researchers found the speedometers read 5 mph too high. Researchers recomputed the coefficient. The new value will be:
Answer:
0.45
Step-by-step explanation:
The correlation coefficient is used to measure the relationship between how two variables change. In this question, the two variables are cars speed and gas mileage. Since the speedometers were wrong as they were 5 mph too high in a constant manner, then the correlation between how changes in speed affect gas mileage will not be changed.
For example, if we are measuring how an increase of 15 mph decreased gas mileage, we are looking at the change in speed and it is the same if we start with 75 mph and then increase speed to 90 mph, or if we start with 45 mph and then increase to 60 mph. The change in speed for both cases will remain unchanged at 10 mph.
Now, since we have seen that the change in speed remains unchanged and since correlation coefficient is a measure of the relationship between how two variables change, then the new value of the correlation coefficient will remain the same as 0.45.
1000 coins are tossed find the probability of getting exactly 500 heads.
Answer:
probability of getting exactly 500 heads= 1
Step-by-step explanation:
If a coin is tossed, the probability of obtaining a head = 0.5
If a coin is tossed, the probability of obtaining a tail= 1- probability of obtaining a head
If a coin is tossed, the probability of obtaining a tail=1-0.5
If a coin is tossed, the probability of obtaining a tail=0.5
So if 1000 coin are tossed, the probability of getting exay 500 heads which is already the half of 1000 is 1

hope this helped you( ꈍᴗꈍ)
Answer:
r = -1/4
Step-by-step explanation:
5r = -3(r + 3) +7
multiplying -3 with r + 3
5r = -3r - 9 +7
taking -3r on the other side of equality sign
5r + 3r = -9 + 7

If the patient is less than 70 years old, the loading dose is 80 Howell Units2 per kilogram of DM. One Howell Unit is equivalent to 0.0020 mg of pure heparin. 2. Calculate how many mg of pure heparin is in 80 Howell Units. Do not worry about the kilograms of DM yet. 00.1600mg The loading dose, in mg of heparin for a 5-year-old with a total body weight of 40 lbs., with 10% bodyfat (that is, 90% of that 40 lbs. is lean body mass). You may also be interested to know that 1 kg = 2.20 lbs. Think about the steps you need to go through to find the correct dose. Remember, first you need to find the dosing mass....
Answer:
1) 0.16 mg of pure heparin is in 80 Howell units
2) the loading dose, in mg of heparin for the 5-year-old boy is 2.618 mg
Step-by-step explanation:
Given that;
if a patient is less than 70 years of age then loading dose is 80 Howell units square per Kg of DM,
One Howell unit is equivalent to 0.0020 mg of pure heparin
1)
how many mg of pure heparin is in 80 Howell units.
that will be;
80 × 0.0020 = 0.16 mg
therefore 0.16 mg of pure heparin is in 80 Howell units
2)
First we find the dosing mass
so dosing mass = body weight of the 5year old boy × 90%
from the question his total body weight of 40 lbs and 1 kg = 2.20 lbs
so
dosing mass = 40lbs × 1kg/2.20lbs × 90/100
dosing mass(kg) = 16.37 kg
Now to calculate the Loading dose we say;
Loading dose = dosing mass × heparin required per kg
Loading dose = 16.36 kg × 0.16 mg heparin per 1kg
loading dose = 2.618 mg heparin
therefore the loading dose, in mg of heparin for the 5-year-old boy is 2.618 mg
