Answer:

45 mins

Step-by-step explanation:

Estimated time it would take to visit with each client = fraction of time required for one client x 60 minutes

3/4 x 60 = 45 minutes

time it would take to visit with 7 clients = 7 x 45 minutes = 5hours 25 mins

Suppose that blood chloride concentration (mmol/L) has a normal distribution with mean 104 and standard deviation 5
Stels [109]

Answer:

a) 0

b) 0.579 is the probability that chloride concentration is less than 105.

c) 0.32 is the probability that chloride concentration differs from the mean by more than 1 standard deviation.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 104

Standard Deviation, σ = 5

We are given that the distribution of blood chloride concentration is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

a) Since normal distribution s a continuous distribution, the probability for a particular value is zero. Therefore,

P(x =105) = 0

b) P(chloride concentration is less than 105)

P(x < 105) = P(z < \displaystyle\frac{105-104}{5}) = P(z < 0.2)

Calculating the value from the standard normal table we have,

P(z

c) P(chloride concentration differs from the mean by more than 1 standard deviation)

Since it is a normal distribution, the Empirical rule shows that 68% falls within the first standard deviation, 95% within the first two standard deviations, and 99.7% within the first three standard deviations.

= 1 - P(chloride concentration within the mean by 1 standard deviation)

= 1 - 0.68 = 0.32

Round your answer to the nearest hundredth LA
m_a_m_a [10]

Answer:

Step-by-step explanation:

Since this is a right triangle, we will use a right triangle trig identity to solve our problem. The side opposite the reference angle A is given as 5, and the side adjacent to the reference angle is given as 7. The trig ratio that uses the sides opposite and adjacent is the tangent ratio:

tanA=\frac{5}{7}

Hit the 2nd button on your calculator then the tan button which displays:

tan^{-1}(

Enter 5/7 after that open parenthesis and hit = to get that

A = 35.54°

Four of the angle of a Pentagon are 70°,90°,100° and 145°. What is the side of a fifth angle?​
dezoksy [38]

Answer: 135°

Step-by-step explanation:

The sum of the angles in a pentagon is equal to 540°, and the sum of the first four angles is 405°.

70 + 90 + 100 + 145 = 405

540 - 405 = 135
