A circle has a circumference of 6. It has an arc of length 1.
Viktor [21]

Answer:

<h3>60°</h3>

Step-by-step explanation:

Given that:

  • Circumference (C) = 6 units
  • Arc length (A) = 1 unit

<u>Find the central angle (</u><u>θ</u><u>)</u>

Arc is some part of circumference; thus,

the equation of arc length =

A = θ/360 × C

θ/360 = A/C

θ = (360×A)/C

θ = (360×1)/6

θ = 360 ÷ 6

<h3>θ = 60° ✅</h3>

Central angle = 60°

If f and g are differentiable functions for all real values of x such that f(1) = 4, g(1) = 3, f '(3) = −5, f '(1) = −4, g '(1)
belka [17]

Answer:

h'(1)=0

Step-by-step explanation:

We use the definition of the derivative of a quotient:

If h(x)=\frac{f(x)}{g(x)}, then:

h'(x)=\frac{f'(x)*g(x)-f(x)*g'(x)}{(g(x))^2}

Since in our case we want the derivative of h(x) at the point x = 1, which is indicated by: h'(1), we need to evaluate the previous expression at x = 1, that is:

h'(1)=\frac{f'(1)*g(1)-f(1)*g'(1)}{(g(1))^2}

which, by replacing with the given numerical values:

f(1) =4\\g(1)=3\\f'(1)=-4\\g'(1)=-3

becomes:

h'(1)=\frac{f'(1)*g(1)-f(1)*g'(1)}{(g(1))^2}=\\=\frac{-4*3-4*(-3)}{(3)^2}=\frac{-12+12}{9} =\frac{0}{9} =0

If a set of sample measurements has a mean of 100, a normal distribution, a standard deviation of 2, and control limits of 94 an
weeeeeb [17]

Answer: 99.73%

Step-by-step explanation:

Given : Mean : \mu=100

Standard deviation : \sigma=2

Let X be the random variable that represents the data values.

Formula for Z-score :  z=\dfrac{X-\mu}{\sigma}

For x=94, we have

z=\dfrac{94-100}{2}=-3

For x=106, we have

z=\dfrac{106-100}{2}=3

The probability that the samples are between 94 and 106:-

P(-3

Hence, the percent of the samples are expected to be between 94 and 106 = 99.73%
