<h2>Answer:</h2>

              The value is:

                      -4

<h2>Step-by-step explanation:</h2>

We are asked to find the value of the ceiling function: \left \lceil -4.6 \right \rceil

As we know that the ceiling function always occupy the higher value in integers.

i.e. the ceiling function act as follows:

it takes value 0 when   -1< x≤0

                       1 when  0 < x ≤ 1

                       2 when  1 < x ≤2

and so on.

As we know that:

            -4.6 lie between -5 and -4.

            Hence, we have:

            \left \lceil -4.6 \right \rceil=-4

Answer:  -4

Step-by-step explanation:

The ceiling function (also known as the least integer function) is written as

f(x) = [x]

It gives the smallest integer greater than or equal to x .

For example : [5.6]=6

or [-1.9]= -1   [∵- 1 > -1.9 ]

To find : The value of [-4.6]

Clearly ,  [-4.6] is written in ceiling function notation.

Then,  [-4.6]  = smallest integer greater than or equal to -4.6

= -4              [∵ -4>-4.6]

Hence, the value of [-4.6] = -4

Find the value of x<br><br>60 <br>58<br>64<br>62​
monitta

Answer:

64

Step-by-step explanation:

The interior angle of a circle has the theorem divide in 2 the sum of the arcs on the circle.

The circle has arcs 42 and 86.

The interior angle is 42 + 86 = 128.

128/2 = 64

Write an equation in slope intercept form for the graph below
labwork [276]

Answer:

y = 10x

Step-by-step explanation:

Finding the slope (m) of the line the following points in the line, (0, 0) and (2, 20):

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{20 - 0}{2 - 0} = \frac{20}{2} = 10

y-intercept (b) is 0. The line intercepts the y-axis at 0. Thus, b = 0.

Substitute m = 10 and b = 0 in y = mx + b

The equation in slope-intercept form for the graph would be:

✅y = 1x + 0

y = 10x

Suppose that X has an exponential distribution with mean equal to 10. Determine the following: a. P(X &gt; 10) b. P(X &gt; 20) c
GrogVix [38]

Answer:

(a) The value of P (X > 10) is 0.3679.

(b) The value of P (X > 20) is 0.1353.

(c) The value of P (X < 30) is 0.9502.

(d) The value of x is 30.

Step-by-step explanation:

The probability density function of an exponential distribution is:

f(x)=\lambda e^{-\lambda x};\ x>0, \lambda>0

The value of E (X) is 10.

The parameter λ is:

\lambda=\frac{1}{E(X)}=\frac{1}{10}=0.10

(a)

Compute the value of P (X > 10) as follows:

P(X>10)=\int\limits^{\infty}_{10} {0.10 e^{-0.10 x}} \, dx \\=0.10\int\limits^{\infty}_{10} { e^{-0.10 x}} \, dx\\=0.10|\frac{e^{-0.10 x}}{-0.10} |^{\infty}_{10}\\=|e^{-0.10 x} |^{\infty}_{10}\\=e^{-0.10\times10}\\=0.3679

Thus, the value of P (X > 10) is 0.3679.

(b)

Compute the value of P (X > 20) as follows:

P(X>20)=\int\limits^{\infty}_{20} {0.10 e^{-0.10 x}} \, dx \\=0.10\int\limits^{\infty}_{20} { e^{-0.10 x}} \, dx\\=0.10|\frac{e^{-0.10 x}}{-0.10} |^{\infty}_{20}\\=|e^{-0.10 x} |^{\infty}_{20}\\=e^{-0.10\times20}\\=0.1353

Thus, the value of P (X > 20) is 0.1353.

(c)

Compute the value of P (X < 30) as follows:

P(X

Thus, the value of P (X < 30) is 0.9502.

(d)

It is given that, P (X < x) = 0.95.

Compute the value of <em>x</em> as follows:

P(X

Take natural log on both sides.

ln(e^{-0.10x})=ln(0.05)\\-0.10x=-2.996\\x=\frac{2.996}{0.10}\\ =29.96\\\approx30

Thus, the value of x is 30.
