Answer:

94 - 82 = 12

Step-by-step explanation:

Ok! Let's try and understand tye concept.

In a box and whisker plot, every vertical line in the box has a unique meaning. There are usually five vertical lines.

1st : LOWEST VALUE

2nd : LOWER QUARTILE

3rd: MEDIAN-

The Middle line is the MEDIAN. What it means is, the exact point where the vertical line intersects with the calibrated horizontal line, that point indicates the MEDIAN

4th: UPPER QUARTILE

5th : HIGHEST VALUE.

THE RANGE is calculated by subtracting the lowest value from the highest value.

That is: from the whisker point on the question-

HIGHEST VALUE = 94

LOWEST VALUE = 82

RANGE = 94 - 82 = 12

Determine the surface area of the cylinder below.

Dahasolnce [82]

Answer:

9π m²

Step-by-step explanation:

We will need calculate the area of the top, the base and sides.

Area of the top=πr²

Area of the base=πr²

Area of the side: 2πrh

Surface area of a cylinder: area of the top + area of the base +area of the side

Surface area of a cylinder=πr²+πr²+2πrh=2πr²+2πrh=2πr(r+h)

Data:

r=1.5 m

h=1.5 m

Surface area of this cylinder=2π(1.5m)(1.5 m+1.5 m)=3π m*(3 m)=9π m².

The patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.3 days and a standard de

inna [77]

Answer:

The probability of spending between 4 and 7 days in recovery

P(4≤x≤7) = 0.5445

Step-by-step explanation:

Step(i):-

Given mean of the Population μ = 5.3 days

Given standard deviation of the population 'σ' = 2 days

Let 'X' be the random variable in normal distribution

Let x₁ = 4

$Z_{1} = \frac{x_{1}-mean }{S.D} = \frac{4-5.3}{2} = -0.65$

Let x₂ = 7

$Z_{2} = \frac{x_{2}-mean }{S.D} = \frac{7-5.3}{2} = 0.85$

Step(ii):-

The probability of spending between 4 and 7 days in recovery

P(4≤x≤7) = P(-0.65≤Z≤0.85)

= P(Z≤0.85) - P(Z≤-0.65)

= 0.5 + A( 0.85) - ( 0.5 - A(-0.65)

= 0.5 + A( 0.85) - 0.5 +A(0.65) ( ∵A(-0.65) = A(0.65)

= A(0.85) + A(0.65)

= 0.3023 + 0.2422

= 0.5445

Final answer:-

The probability of spending between 4 and 7 days in recovery

P(4≤x≤7) = 0.5445
