Answer:236,520 hours
Step-by-step explanation:
You multiply the years(27) times the number of days in one year(365) which equals 9,855 and then you multiply that by the number of hours in a day(24) so it equals 236,520.

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)
3. Lonnie has a gift card worth $600 for a local entertainment store. Movies cost $20 each and newly released video games cost $50 each. In order to use the gift card, Lonnte must purchase
at least thirteen items. Which is a combination of movies and newly released video games that Lonnie could purchase using his gift card? (2 points)
6 movies and 4 video games
14 movie and 7 video games
O O O O
2 movies and 10 video games
8 movies and 6 video games
Answer:
8 movies and 6 video games
Step-by-step explanation:
Given
[tex]Gift\ Card = \$600[/tex]
[tex]Movies =\ $20[/tex]
[tex]Video\ Game = \$50[/tex]
[tex]Minimum\ Items = 13[/tex]
Required
Determine the items Lonnie can afford
To solve this question, we make use of trial by error method by taking the options one at a time:
Option 1: 6 movies and 4 video games
This option can not be considered because the number of items is not up to the minimum Lonnte must purchase.
Option 2: 14 movies and 7 video games
[tex]Cost = 14 * \$20 + 7 * \$50[/tex]
[tex]Cost = \$280 + \$350[/tex]
[tex]Cost = \$630[/tex]
This option can not be considered because the cost of purchase is greater than Lonnte's worth of Gift card.
Option 3: 2 movies and 10 video games
This option can not be considered because the number of items is not up to the minimum Lonnte must purchase.
Option 4: 8 movies and 6 video games
[tex]Cost = 8 * \$20 + 6 * \$50[/tex]
[tex]Cost = \$160 + \$300[/tex]
[tex]Cost = \$460[/tex]
Hence, the correct option is 8 movies and 6 video games

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".

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:

∑ 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).
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

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.

Step-by-step explanation:
Let be [tex]f(s,t) = \sqrt{s^{2}+t^{2}}[/tex], the range of a square root compehends the subset of positive real numbers plus zero. Likewise, the range of the square of any number has the same subset with all real set as domain. As square root encloses a sum of squares, the domain of the function is:

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.

1992.38
Step-by-step explanation:
The mean, or average, of a set of data points is found by adding all the values together and dividing by the number of values.
Sum:
1911.56 + 1956.69 + 1903.16 + 1958.82 + 1910.87 + 1983.14 + 2014.12 + 2023.86 + 2057.26 + 2034.21 + 2087.73 + 2067.14 = 23908.56
Divide:
There are 12 numbers, so divide 23908.56 by 12:
23908.56 / 12 = 1992.38
The average is thus 1992.38.

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
8r = -2
dividing 8 by -2
r = -2/8
simplifying -2/8
r = -1/4

In order to find the zeros of f(x)=x2−8x+12, Jessica needs to first factor the quadratic function. Which of the following is the factored form of the function?
If f(x) = 3^x
+ 10 x and g(x) = 5x - 3, find ( f - g )(x).
Subtract the functions to get that answer
(f - g)(x) = f(x) - g(x)
(f - g)(x) = [ f(x) ] - [ g(x) ]
(f - g)(x) = [ 3^x + 10x ] - [ 5x - 3 ]
(f - g)(x) = 3^x + 10x - 5x + 3
(f - g)(x) = 3^x + 5x + 3
Answer:
