\qquad \qquad  \bf \huge\star \:  \:  \large{  \underline{Answer} }  \huge \:  \: \star

  • y - intercept = -3

\textsf{  \underline{\underline{Steps to solve the problem} }:}

Equation of straight line in point - slope form :

\qquad❖ \:  \sf \:y - y1 = m(x - x1)

( m = slope = 4, point (5 , 17) )

\qquad◈  \:  \:  \sf \: y - 17 = 4(x - 5)

\qquad◈  \:  \:  \sf \: y  - 17= 4x - 20

\qquad◈  \:  \:  \sf \: y = 4x - 20 + 17

\qquad◈  \:  \:  \sf \: y = 4x - 3

Now, it's the form of line in slope - intercept form, ( slope = coefficient of x = 4 and y - intercept = -3 )

\qquad \large \sf {Conclusion}  :

\qquad◈  \:  \:  \sf \: y \:  \: int =  - 3

Answer:

The probability that none of the LED light bulbs are​ defective is 0.7374.

Step-by-step explanation:

The complete question is:

What is the probability that none of the LED light bulbs are​ defective?

Solution:

Let the random variable <em>X</em> represent the number of defective LED light bulbs.

The probability of a LED light bulb being defective is, P (X) = <em>p</em> = 0.03.

A random sample of <em>n</em> = 10 LED light bulbs is selected.

The event of a specific LED light bulb being defective is independent of the other bulbs.

The random variable <em>X</em> thus follows a Binomial distribution with parameters <em>n</em> = 10 and <em>p</em> = 0.03.

The probability mass function of <em>X</em> is:

P(X=x)={10\choose x}(0.03)^{x}(1-0.03)^{10-x};\ x=0,1,2,3...

Compute the probability that none of the LED light bulbs are​ defective as follows:

P(X=0)={10\choose 0}(0.03)^{0}(1-0.03)^{10-0}

                =1\times 1\times 0.737424\\=0.737424\\\approx 0.7374

Thus, the probability that none of the LED light bulbs are​ defective is 0.7374.

When converting from inches to feet, the measurement in inches, m, of an object varies directly with its measurement in feet, f,
jonny [76]

Step-by-step explanation:

wow, how complicated can one phrase this ...

the point being :

1 ft = 12 in and vice versa (1 in = 1/12 ft)

so, any measurements given in feet but needed in inches need to be multiplied by 12.

and any measurements given in inches but needed in feet need to be divided by 12.

so,

3.5 ft = 3.5×12 = 7/2 × 12 = 7×6 = 42 in

27 in = 27/12 = 9/4 = 2 1/4 or 2.25 ft

What is the slope of the line shown below?
Thepotemich [5.8K]

Answer:

○ A. \frac{6}{5}

Step-by-step explanation:

Starting from the y-intercept of [0, 5], you do \frac{rise}{run}by either moving six blocks <em>south</em><em> </em>over five blocks <em>west</em><em> </em>or six blocks <em>north</em><em> </em>over four blocks <em>east</em><em> </em>[<em>west</em><em> </em>and <em>south</em><em> </em>are negatives].

I am joyous to assist you anytime.
