Work out the difference in minutes between 2 hour 35 minutes and 1 3/4 hours
Answer: The difference in minutes between 2 hours 35 minutes and 1 3/4 hours is 30 minutes.
Step-by-step explanation:
To find the difference in minutes between 2 hours 35 minutes and 1 3/4 hours, we can first convert 1 3/4 hours to minutes.
There are 60 minutes in 1 hour, so 1 3/4 hours is equal to 1 + 3/4 = 1 3/4 hours = 1.75 hours.
Since there are 60 minutes in 1 hour, 1.75 hours is equal to 1.75 * 60 = 105 minutes.
Then, we can subtract 105 minutes from 2 hours 35 minutes to find the difference in minutes:
2 hours 35 minutes - 105 minutes = 135 minutes - 105 minutes = 30 minutes
So, the difference in minutes between 2 hours 35 minutes and 1 3/4 hours is 30 minutes.

The probabilities, using the Poisson distribution, are given as follows:
11. A shark attack next year: 0.038.
12. More than one shark attack next year: 0.001.
13. At least one shark attack in the next 100 years: 0.982.
What is the Poisson distribution?In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following equation:
[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
The parameters are:
x is the number of successes that we want to find the probability of.e = 2.71828 is the Euler number[tex]\mu[/tex] is the mean in the given interval or range of values of the input parameter.Considering that there have been 8 attacks in 200 years, the mean for n years is given as follows:
[tex]\mu = \frac{8n}{200}[/tex]
Hence the probability of one shark attack in the next year(n = 1, mean = 0.04) is given as follows:
[tex]P(X = 1) = \frac{e^{-0.04}(0.04)^{1}}{(1)!} = 0.038[/tex]
The probability of more than one shark attack is obtained as follows:
P(X > 1) = 1 - P(X ≤ 1)
In which:
P(X ≤ 1) = P(X = 0) + P(X = 1).
Then:
P(X = 0) = e^(-0.04) = 0.961.P(X = 1) = 0.038.Thus:
P(X > 1) = 1 - (0.961 + 0.038) = 0.001.
For 100 years, the mean is of:
100 x 8/200 = 4.
Thus the probability of at least one attack is of:
P(X > 0) = 1 - e^(-4) = 0.982.

Christa purchased ten bottles of shampoo in each of three different sizes: 312 ounces; 612 ounces; and 812 ounces. She used the expression (10×312)+(10×612)+(10×812) to show the total amount of shampoo purchased in ounces. Which expression is equivalent to the one Christa used?
Answer:
(10 * 312) + (10 * 612) + (10 * 812)
Step-by-step explanation:
To find the total amount of shampoo that Christa purchased in ounces, we can use the expression (10 * 312) + (10 * 612) + (10 * 812), which is equivalent to the expression that Christa used. This expression is also equivalent to 3120 + 6120 + 8120, which can be simplified to 3120 + 6120 + 8120 = 3120 + 6150 + 8100 = 9280 + 6150 = 15,430. Therefore, the expression (10 * 312) + (10 * 612) + (10 * 812) is equivalent to 15,430.

The value of c in the interval (-4 , -3) is -√12 such that f'(c) = 0 as
f'(-√12) = 0, so c = -√12.
Given, the function below satisfies Rolle's Theorem on the specified interval.
we have to find the value of c in the interval (-4 , -3) such that
f'(c) = 0.
the function given is,
f(x) = x + 12/x
First we have to find the derivative of the given function f(x).
f(x) = x + 12/x
f'(x) = 1 - 12/x²
Now, equating the derivative with 0 we get
f'(x) = 0
1 - 12/x² = 0
1 = 12/x²
x² = 12
x² - 12 = 0
(x + √12)(x - √12) = 0
x = √12 or x = -√12

The correct equation is t = 5 seconds.
What is equation ?
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.
Let me mention first that there is an error in the statement that the gravitational pull of the Earth is 16 ft/s^2. It is in fact 32 ft/s^2, and the actual equation uses half of the acceleration multiplied by the square of the variable time, so it gives as final expression :
y(t) = -16t² + 0t + 400
and we want to find the value/s for "t" that make this equation equal zero (when it reaches the ground and the object just touches the ground. This makes the equation we want to solve:
0 = -16t² + 0t + 400
16t² + 0t - 400 = 0
which solving for "t" becomes:
16t² - 400 = 0
16t² = 400
t² = 25
t = √25
t = ± 5
So we adopt the positive answer (positive time) since the negative value has no physical meaning for this problem.
That is: t = 5 seconds

The term Normal Distribution is defined as a continuous probability distribution where the values lie in a symmetrical fashion mostly situated around mean .
it is given that ,probability(p) of landing marble on ground is 25% = 0.25
game is played for 30 rounds (n) = 30 ; q = 1 - 0.25 = 0.75 .

a television camera is positioned 4,000 ft from the base of a rocket launching pad. the angle of elevation of the camera has to change at the correct rate in order to keep the rocket in sight. also, the mechanism for focusing the camera has to take into account the increasing distance from the camera to the rising rocket. let's assume the rocket rises vertically and its speed is 900 ft/s when it has risen 3,000 ft. (Round your answers to three decimal places.) (a) How fast is the distance from the television camera to the rocket changing at that moment? 480 ft/s (b) If the television camera is always kept aimed at the rocket, how fast is the camera's angle of elevation changing at that same moment? 0.002 rad/s
For the given height and distance the answer of the following questions are:
a. Change in distance between the camera to the rocket at that moment is equal to 540ft/sec.
b. Change in the angle of elevation is equal to 0.144rad/sec.
As given in the question,
Let 'α' be the angle of elevation
'h' be the height of the rocket
'x' be the distance between the camera and the rising rocket.
a. Relation between x , h, and 4000 ft during launching pad is given by Pythagoras theorem:
x² = h² + 4000²
Differentiate with respect to time 't' we get,
2xdx/dt = 2hdh/dt + 0 __(1)
When h = 3000ft
x² = 3000² + 4000²
⇒x = 5000ft
dh/dt = 900ft/s
Substitute all values in (1) we get,
2(5000)dx/dt= 2(3000)(900)
⇒dx/dt = 5,400,000/ 10,000
⇒dx/dt = 540ft/sec.
b. tanα = h/4000 __(2)
when h = 3000ft
tanα = 3/4
⇒α = 0.6435
Differentiate (2) with respect to t we get,
sec²α dα/dt = (1/4000) dh/dt
⇒sec²(0.6435) dα/dt = (1/4000)(900)
⇒dα/dt = (0.225)/ 1.5625
⇒dα/dt = 0.144 rad/ sec.
Therefore, for the given height and distance the answer of the following questions are:
a. Change in distance between the camera to the rocket at that moment is equal to 540ft/sec.
b. Change in the angle of elevation is equal to 0.144rad/sec.

7 the area of the rhombus
The area of a rhombus is --336[tex]in^{2}[/tex]
A rhombus is a type of parallelogram where all the sides are equal in length. opposite sides of a rhombus are parallel to each other and opposite angles are equal.
The diagonals of a rhombus bisect each other at the right angle.
side of a rhombus (x) is - 25inone diagonal of a rhombus(a) is - 14inlet, another diagonal of a rhombus is -b in
another diagonal of a rhombus, b = [tex]\sqrt{4x^{2} -a^{2} }[/tex]
= [tex]\sqrt{4*25^{2} - 14^{2} }[/tex]
=[tex]\sqrt{4*625 - 196}[/tex]
=[tex]\sqrt{2500 - 196}[/tex]
= [tex]\sqrt{2304}[/tex]
= 48 in
Area of the rhombus (A) = [tex]\frac{a * b }{2}[/tex]
= [tex]\frac{14 * 48 }{2}[/tex] [tex]in^{2}[/tex]
= 7 * 48 [tex]in^{2}[/tex]
= 336 [tex]in^{2}[/tex]
The area of a rhombus is --336[tex]in^{2}[/tex]

The length of a rectangle is 5cm longer than its width. If the perimeter of the rectangle is 74cm , find its length and width.
Answer:
The width of the rectangle is 32cm and the length is 37cm.
Step-by-step explanation:
Let's call the width of the rectangle "w" and the length of the rectangle "l".We know that the perimeter of the rectangle is equal to 2 times the sum of the length and the width, or 2(w+l) = 74.We also know that the length is 5cm longer than the width, so we can set up the equation l = w + 5.We can substitute this expression for l in our first equation to get 2(w + (w + 5)) = 74.Combining like terms, we get 2w + 10 = 74.Dividing both sides by 2, we get w = 32.We can now use this value to find the length of the rectangle.Thus, the width of the rectangle is 32cm and the length is 37cm.david and amy start at the same point and begin biking in different directions. david is biking west at a speed of 17 miles per hour. amy is biking south at a speed of 15 miles per hour. after how many hours will they be exactly 23 miles apart? round your answer to two decimal places.
The Time taken for David and Amy to be exactly 23 miles apart is 1.014 Hours.
Let [tex]t[/tex] be the time taken to reach 23 miles apart from a single point.
David and Amy start at same point and move towards different directions, making them move at perpendicular to each other.
According to Pythagoras theorem, and distance = Speed x time.
[tex](17t)^2 + (15t)^2 = 23^2[/tex]
[tex]289t^2 + 225t^2 = 529[/tex]
[tex]\therefore 514t^2 = 529[/tex]
[tex]t^2 = \frac{529}{514}[/tex]
[tex]t^2 = 1.029[/tex]
[tex]\therefore t = \sqrt{1.029} = 1.014 \text{ hours}[/tex]
