If the mean time between unscheduled maintenance of LCD displays in a hospital's CT scan facility is 4,000. The probability of unscheduled maintenance in exactly 5,000 hours is:.7135.

Using this formula to the probability of unscheduled maintenance in exactly 5,000 hours

P ( X < 5000) = 1 - e^(-λx)

Where:

e = exponent

-λ = Operating hour

x = Number of hours

Let plug in the formula

P ( X < 5000) = 1 - e^(-(1/4000) × 5000)

P ( X < 5000) = 1- e^-1.25

P ( X < 5000)  = 1 - .2865

P ( X < 5000)  = .7135

Therefore the probability is .7135.

Using the Time-Distance Formula, it will take Adbi 2 hours.

We can use the time-distance formula to find how long it will take for Abdi to catch up with Bashir. The time-distance formula is distance = speed x time.

Let t be the time in hours that it takes for Abdi to catch up with Bashir.

We know that the distance Abdi has covered is 4 miles more than Bashir, and the relative speed between the two runners is 8mph - 6mph = 2mph.

So we can write the equation:

4 = (8 - 6) * t

Solving for t, we get t = 4/2 = 2 hours.

So it will take Abdi 2 hours to catch up with Bashir.

The velocity after 3 second is -118 ft/sec and the velocity after falling 108 feet is -87.6 ft/sec.

(a)

For the given position function

[tex]s(t)=-16t^2+v_0.t+s_0[/tex]

The ball is dropped from top of the building of height 220 ft, therefore

[tex]s_0=220ft[/tex]

Also, the initial velocity of the ball is −22 feet per second, thus.

[tex]v_0=22\frac{ft}{s}[/tex]

We will differentiate the position function to find the velocity function and then calculate velocity at (a) t=3sec and (b) after failing 108 ft.

Differentiate Position function to acquire the velocity function v(t).

[tex]s(t)=-16t^2+v_0.t+s_0\\\\s'(t)=-32t+v_0[/tex]

Now substitute t=3s,

v(3) = -32(3) + (-22)

v(3)= -118 ft/sec

b)

To find the velocity of ball after falling 108 ft, first we need to find the time at which ball is dropped 108 ft. and then find velocity at that time using velocity function.

let s(t)=108 ft, then using position function, we can write

[tex]s(t)=-16.t^2+v_0t+s_0\\\\108=-16t^2+(-22)t+220\\\\-16t^2-22t+112=0[/tex]

After solving the quadratic equation, we get

t= -3.42 and 2.05

Since time always positive,

therefore t=2.05 sec.

v (2.05) = -32(2.05)-22

v (2.05) = -87.6 ft/sec

By the distance formula, [tex]f(a)=\sqrt{a^2+(a^2+3)^2}[/tex].

Clearly, [tex]f(a)[/tex] is minimized when the radicand is minimized.

Clearly, the radicand is always increasing, so the minimum is achieved at the left endpoint of the maximal domain of [tex]f(a)[/tex], which is [tex]a=0[/tex].

So, the coordinates are [tex](0,-2)[/tex].

The point on the curve y = -x^2 - 2 that is closest to the point (0, 1) will be (0, -2)

From the information, we want to know the point on the curve y = -x^2 - 2 that is closest to the point (0, 1).

Let the coordinates of the desired point be illustrated as (a - a² - 2).

The distance of the point from (0, 1) is depicted as f(a).

When the radicand is minimized, f(a) is minimized.

In this case, the minimum will be achieved at the left endpoint of the maximal domain of f(a) which is a = 0.

While the new helmets decrease the probability of injury resulting from a scooter accident, but they also incentivize individuals to ride more recklessly, which could increase the number of scooter collisions and therefore injuries to renters.

The reason for the above statement is based on the concept of risk compensation. When the perceived risk of an activity is reduced, individuals may engage in more risky behavior. For example, if individuals believe that wearing a helmet makes them safer while riding a scooter, they may feel less concerned about the potential consequences of riding recklessly, leading to an increase in the number of accidents. On the other hand, the helmet does decrease the probability of injury in the event of a crash, but an increase in the number of crashes could lead to an overall increase in the number of injuries, offsetting the protective effect of the helmets. Therefore, the net impact of the new helmets on the number of scooter injuries is unclear, and further study is needed to determine their overall effect.

Answer:

-1

Step-by-step explanation:

Add 2 to both sides of the equation: -7 + 2 = 5x - 2 + 2. This gives you -5 = 5x.

Divide both sides of the equation by 5: -5/5 = 5x/5. This gives you -1 = x.

So the solution to the equation is x = -1.

Alternatively, you can also use inverse operations to solve the equation by isolating x to one side.

Add 2 to both sides of the equation: -7 + 2 = 5x - 2 + 2. This gives you -5 = 5x

Divide both sides of the equation by 5: -5/5 = 5x/5. This gives you -1 = x

So the solution to the equation is x = -1.

The quadrilaterals in a and b have the missing values of x as 85° and 57° respectively and can be best described as a scalene quadrilateral.

A scalene quadrilateral is a four-sided polygon in which all four sides have different lengths and all four angles have different measures. This is also known as an asymmetric quadrilateral.

we shall evaluate for the missing values of x as follows:

x + 109° + 96° + 70° = 360° {sum of interior angles of a quadrilateral}

x + 275° = 360°

x = 360° - 275° {subtract 275° from both sides}

x = 85°

x + 85° + 94° + (180° - 58°) = 360° {sum of interior angles of a quadrilateral}

x + 301 = 360°

x = 360° - 303° {subtract 303° from both sides}

x = 57°

Therefore, the missing values of x for quadrilaterals in a and b are 85° and 57° respectively, and can be best described as a scalene quadrilateral.

Answer: The total bill including tax and gratitude is $35.20

And each one of the 5 friends paid $10 for the bill.

So the total amount paid is $10*5 = $50

If each person paid $10 and the total bill was $35.20

then the change will be $50-$35.20 = $14.80

And since they split the bill equally then each one of them will get back $14.80/5 = $2.96

So each person will get back $2.96

Step-by-step explanation:

To solve the system of equations using elimination, we can follow these steps:

Multiply the first equation by 4, and the second equation by 2:

20x + 8y = 12

8x - 16y = 24

Add the two equations together:

20x + 8y = 12

8x - 16y = 24

28x - 8y = 36

Solve for x by dividing both sides of the equation by 28:

x = 36/28 = 9/7

Substitute the value of x back into one of the original equations:

5x + 2y = 3

5(9/7) + 2y = 3

45/7 + 2y = 3

2y = -42/7

Solve for y by dividing both sides by 2:

y = -21/7

So the solution of the system of equations is (x,y) = (9/7, -21/7)

It is also worth noting that we could have also multiplied the first equation by -2 and the second equation by 5 and added them together, this will also lead us to the same solution.

The slope of the line is (4-(-4))/(7-1) = 8/6 = 4/3.

The y-intercept is -4.

So the equation of the line is y = (4/3)x - 4.

We know that the area of triangle BCD is 15 square units. To find the possible coordinates of point D, we can use the formula for the area of a triangle (A = (1/2)bh). Since we know the area and the base, we can find the height of the triangle and use that to find the possible coordinates of point D.

The equation of the line is y = (4/3)x - 4. We can use this equation to find the y-coordinate of point D.

y = (4/3)x - 4

15 = (1/2)(x)((4/3)x - 4)

By solving the equation above, we can find the possible x coordinate of point D, which are (-2, -4/3) and (12, 4). Therefore, the possible coordinates of point D are (-2, -4/3) and (12, 4).
