Find the length of side x in simplest radical form with rational denominator.
DaniilM [7]

Answer:

sqrt(20)

Step-by-step explanation:

The two perpendicular side lengths are equal, so using Pythagoras theorem:

x = sqrt( sqrt(10)^2 + sqrt(10)^2 )

x = sqrt(10 + 10)

x = sqrt(20)

Suppose that the current measurements in a strip of wire are assumed to follow a normal distribution with a mean of 10 millimete
KiRa [710]

Answer: the probability that a measurement exceeds 13 milliamperes is 0.067

Step-by-step explanation:

Suppose that the current measurements in a strip of wire are assumed to follow a normal distribution, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = current measurements in a strip.

µ = mean current

σ = standard deviation

From the information given,

µ = 10

σ = 2

We want to find the probability that a measurement exceeds 13 milliamperes. It is expressed as

P(x > 13) = 1 - P(x ≤ 13)

For x = 13,

z = (13 - 10)/2 = 1.5

Looking at the normal distribution table, the probability corresponding to the z score is 0.933

P(x > 13) = 1 - 0.933 = 0.067

Can somebody help me with this
kipiarov [429]

Answer:

The answer to your question is letter A. \frac{5}{13}

Step-by-step explanation:

Cosine is the trigonometric function that the adjacent side and the hypotenuse.

Formula

                         cos x = \frac{adjacent side}{hypotenuse}

For x:

Adjacent side = 5

Hypotenuse = 13

Substitution

                       cos x = \frac{5}{13}
