Suppose that lithium calculator battery with a charge of 3 volts, actually has a voltage with uniform distribution between 2.93
Dmitrij [34]

Answer:

b. E(X) = 3.015, STDEV(X)= 0.049, P (X ≤ 2.98) = 0.2941

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The mean of the uniform probability distribution is:

M = \frac{a + b}{2}

The standard deviation of the uniform distribution is:

S = \sqrt{\frac{(b-a)^{2}}{12}}

The probability that we find a value X lower than x is given by the following formula.

P(X \leq x) = \frac{x - a}{b-a}

Uniform distribution between 2.93 and 3.1 volts

This means that a = 2.93, b = 3.1. So

Mean:

M = \frac{2.93 + 3.1}{2} = 3.015

Standard deviation:

S = \sqrt{\frac{(3.1 - 2.93)^{2}}{12}} = 0.049

What is the probability that a battery has a voltage less than 2.98?

P(X \leq 2.98) = \frac{2.98 - 2.93}{3.1 - 2.93} = 0.2941

So the correct answer is:

b. E(X) = 3.015, STDEV(X)= 0.049, P (X ≤ 2.98) = 0.2941

A construction company showed that the strength, y, of concrete, measured
Vilka [71]

Answer:

  a) y-intercept = 17; initial design strength percentage

  b) slope = 2.8; increase in that percentage each day

  c) 29.6 days to 100% design strength

Step-by-step explanation:

a, b) The equation is in the form called "slope-intercept form."

  y = mx + b

where the slope is m, and the y-intercept is b.

Your equation has a slope of 2.8 and a y-intercept of 17.

The y-intercept is the percentage of design strength reached 0 days after the concrete is poured. The strength of the concrete when poured is 17% of its design strength.

The slope is the percentage of design strength added each day after the concrete is poured. The concrete increases its strength by 2.8% of its design strength each day after it is poured.

__

c) To find when 100% of design strength is reached, we need to solve for x:

  100 = 2.8x +17

  83 = 2.8x

  83/2.8 = x ≈ 29.6

The concrete will reach 100 percent of its design strength in about 30 days.

N.6 Properties of parallelograms
PolarNik [594]

Answer:

J=63

Step-by-step explanation:

3b+27=2b+57

subtract 27 from both sides

3b=2b+30

subtract 2b from both sides

b=30

K+J=180

substitute the value of b into K

2(30)+57+J=180

117+J=180

subtract 117 from both sides

J=63
