What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
A hospital has three independent fire alarm systems, with reliabilities of 0.95, 0.97, and 0.99.
This means,
The probability that one alarm will give a warning = 0.95
The probability that one alarm will give a warning = 0.97
The probability that one alarm will give a warning = 0.99
Combining each of them we get,
0.95 + 0.97 + 0.99 = 2.91
Divide by 3.
= 2.91 / 3
= 0.97
This means,
The probability that a warning would be given is 0.97.
Thus,
The probability that a warning would be given is 0.97.

On a winter day in Alaska, the temperature at noon was -0.6°C. From noon to 3:00, the temperature increased by 1.2°C. From 3:00 to 6:00, it dropped 0.4°C, and from 6:00 to 9:00, it decreased by 0.6°C. What expression shows the temperature in °C at 9:00 p.m.?
At 9:00 p.m, the temperature would be equal to -0.4°C
How are Kelvin, Celsius, and Fahrenheit related?We have got an equation that can relate these three units of measurement of temperature, as given below:
[tex]\dfrac{C}{5} = \dfrac{F - 32}{9} = \dfrac{K - 273}{5}[/tex]
where C represents the measurement of a fixed temperature in celsius, F represents the measurement of that same intensity temperature in fahrenheit, and K represents the measurement of equally intense temperature in kelvin.
We are given that
On a winter day in Alaska, the temperature at noon = -0.6°C.
Then From noon to 3:00, the temperature increased by 1.2°C. From 3:00 to 6:00, it dropped 0.4°C, and from 6:00 to 9:00, it decreased by 0.6°C.
-0.4

The ratio of the height to the width of a packaging label is 5 to 19. If the height of the label is 2 inches, what is its width? HINT: Set up and solve as a proportion and find x.
Answer:
7.6 inches
Step-by-step explanation:
The ratio of the height to the width of a packaging label is 5 to 19, that is,
h/w = 5/19 [1]
If the height of the label is 2 inches, and its width is unknown (x), that is,
h/w = 2 in/x [2]
We can set up a proportion with [1] and [2],
5/19 = 2 in/x
We use the cross product property of proportions.
5 × x = 19 × 2 in
x = 19 × 2 in/ 5 = 7.6 in
The width is 7.6 inches.

Dots sells T-shirts ($2) and shorts ($3). In April, total sales were $576. People bought 3 times as many T-shirts as shorts.
How many T-shirts and shorts did Dots sell?
Final answer:
Dots sold 192 T-shirts and 64 shorts in April. We found this by setting up a system of equations with the given information and solving for the number of T-shirts (T) and shorts (S) sold.
Explanation:
To solve the problem of how many T-shirts and shorts Dots sold, we use a system of equations. Let's denote the number of T-shirts as T and the number of shorts as S. Given that T-shirts cost $2 each and shorts cost $3 each, and the total sales were $576, we can write our equations as follows:
2T + 3S = $576
We are also told that the store sold 3 times as many T-shirts as shorts, which gives us the second equation:
T = 3S
Substituting the second equation into the first, we get:
2(3S) + 3S = $576
6S + 3S = $576
9S = $576
Now, dividing both sides by 9 to isolate S, we get:
S = $576 / 9
S = 64
Since T is three times S:
T = 3 × 64
T = 192
Therefore, Dots sold 192 T-shirts and 64 shorts in April.

What is the median of 26, 30, 24, 32, 32, 31, 27, and 29? 32 29 30 29.5?
To find the median, sort the numbers in ascending order and average the two middle values. The median of the given numbers is 29.5.
To find the median of the numbers 26, 30, 24, 32, 32, 31, 27, and 29, follow these steps:
First, arrange the numbers in ascending order: 24, 26, 27, 29, 30, 31, 32, 32.Since there are 8 numbers (an even number), the median will be the average of the 4th and 5th numbers in this sorted list.The 4th number is 29 and the 5th number is 30.The median is therefore (29 + 30) / 2 = 29.5.Thus, the median of the given set of numbers is 29.5.

Find the absolute extrema of the function \(f(x)= xe^{- x^2/18}\) on the interval \([-2,4]\).
Use logarithmic differentiation to find the derivative of the function. y = (x3 + 2)2(x4 + 4)4
The derivative of y = (x³ + 2)²(x⁴ + 4)⁴ using logarithmic differentiation is;
y' = {[6x²In(x³ + 2)]/(x³ + 2)} + {[16x³In(x⁴ + 4)⁴]/(x⁴ + 4)} × [(x³ + 2)²(x⁴ + 4)⁴]
We are given the function;
y = (x³ + 2)²(x⁴ + 4)⁴
We want to find the derivative using logarithmic differentiation;
Step 1; Take the natural log of both sides;
In y = In[(x³ + 2)²(x⁴ + 4)⁴]
Step 2;
Using log of a product property on this, we have;
In y = In(x³ + 2)² + In(x⁴ + 4)⁴
Step 3; We will now differentiate both sides with chain rule to get;.
y'/y = [6x²In(x³ + 2)]/(x³ + 2) + [16x³In(x⁴ + 4)⁴]/(x⁴ + 4)
Step 4; Using multiplication property of equality, multiply both sides by y to get;
y' = {[6x²In(x³ + 2)]/(x³ + 2) + [16x³In(x⁴ + 4)⁴]/(x⁴ + 4)} × y
Step 5; Plug in the value of y = (x³ + 2)²(x⁴ + 4)⁴ to get;
y' = {[6x²In(x³ + 2)]/(x³ + 2)} + {[16x³In(x⁴ + 4)⁴]/(x⁴ + 4)} × [(x³ + 2)²(x⁴ + 4)⁴]

if s(x)=x-7 and t(x)=4x^2-x+3 , which expression is equivalent to (t*s)(x)
Answer:
The answer is [tex]4x^3-29x^2+10x-21[/tex]
Step-by-step explanation:
In order to determine the answer, we have to know what it means (t*s)(x).
When we need to multiply two functions, where y(x) and z(x) are the functions, we can describe the process with the notation (y*z) (x). This notation means that the function y(x) is being multiplying by the function z(x).
So, in this case, we have two functions:
[tex]s(x)=x-7\\t(x)=4x^2-x+3[/tex]
Multiplying both functions (t*s) (x):
[tex](t*s)(x)=t(x)*s(x)\\(4x^2-x+3)(x-7)\\4x^3-28x^2-x^2+7x+3x-21\\4x^3-29x^2+10x-21[/tex]
Finally, the expression is:

a pail holds 4 4/1 gallons of water.How much is this in cups
To convert gallons to cups, multiple conversion factors can be used. Assuming a typo in '4 4/1 gallons' and correcting it to '4 gallons,' the conversion shows that there are 16 cups in a gallon. Thus, 4 gallons of water is equivalent to 64 cups.
Explanation:To convert gallons to cups, you can use conversion factors that relate these two units of volume. First, we need to correct the expression given for the volume of water in the pail. It seems there is a typo because '4 4/1 gallons' isn't a proper number. Assuming it's intended to be '4 gallons,' we can proceed with the conversion.
Since 1 gallon is equivalent to 4 quarts and 1 quart is equivalent to 2 pints, and 1 pint is equivalent to 2 cups, we can create a chain of multiplications to convert from gallons to cups.
1 gallon = 4 quarts1 quart = 2 pints1 pint = 2 cupsMultiplying these together gives us:
1 gallon = 4 x 2 x 2 = 16 cups
Therefore, to find out how many cups are in 4 gallons:
4 gal x 16 cups/gal = 64 cups
So, 4 gallons of water is equivalent to 64 cups.
Final answer:
To convert 4 gallons to cups using the provided conversion factors, multiply the gallons by 4 to get quarts, then multiply by 2 to get pints, and again multiply by 2 to get cups, resulting in a total of 64 cups.
Explanation:
The student's question involves converting a quantity of gallons into cups, which is a Mathematics problem specifically dealing with units of volume conversion. The amount given, 4 4/1 gallons, seems to be a typo, but assuming the intention was to convert 4 gallons into cups, we can use the given conversion factors:
1 gallon = 4 quarts1 quart = 2 pints1 pint = 2 cupsTo find out how many cups are in 4 gallons, we follow these steps:
Multiply the number of gallons by 4 to convert gallons to quarts.Since 1 gallon is equal to 4 quarts, 4 gallons is equal to 4 x 4 quarts, which is 16 quarts.Since 1 quart is equal to 2 pints, we can then convert quarts to pints by multiplying the number of quarts by 2.16 quarts is equal to 16 x 2 pints, which is 32 pints.Finally, since 1 pint is equal to 2 cups, to convert pints to cups, multiply the number of pints by 2.32 pints is equal to 32 x 2 cups, which equals 64 cups.Therefore, 4 gallons is equivalent to 64 cups.
