The times to process orders at the service counter of a pharmacy are exponentially distributed with mean 1 0 minutes. If 100 cus

g100num [7]

Answer:

Therefore, the probability that at least half of them need to wait more than 10 minutes is 0.0031.

Step-by-step explanation:

The formula for the probability of an exponential distribution is:

P(x < b) = 1 - e^(b/3)

Using the complement rule, we can determine the probability of a customer having to wait more than 10 minutes, by:

p = P(x > 10)

= 1 - P(x < 10)

= 1 - (1 - e^(-10/10) )

= e⁻¹

= 0.3679

The z-score is the difference in sample size and the population mean, divided by the standard deviation:

z = (p' - p) / √[p(1 - p) / n]

= (0.5 - 0.3679) / √[0.3679(1 - 0.3679) / 100)]

= 2.7393

Therefore, using the probability table, you find that the corresponding probability is:

P(p' ≥ 0.5) = P(z > 2.7393)

P(p' ≥ 0.5) = 0.0031

Therefore, the probability that at least half of them need to wait more than 10 minutes is 0.0031.

A triangular pyramid has a base with an area of 43 cm squared and lateral faces with bases of 10 cm and heights of 8.6 cm. What

Jet001 [13]

Answer:

The total surface area of triangular pyramid is 172 cm squared

Step-by-step explanation:

Triangular pyramid:

Number of faces 4.
Number of vertices of a triangular pyramid is 6.
The volume is $\frac13 AH$ . A= area of the pyramid's base and H= height of the pyramid.

The surface area of triangular pyramid B+L. B= area of base, L= area of lateral surface.

Given that, the area of the base is 43 cm squared. Lateral faces with bases of 10 cm and heights 8.6 cm.

The 3 sides of the triangular pyramid is triangle in shape.

The area of triangle is $\frac12 \times base \times height$ .

The lateral surface area of the triangular pyramid is

$=3(\frac12 \times base \times height)$

$=3(\frac12\times 10\times8.6)$ cm squared

=129 cm squared

The total surface area of triangular pyramid is

=Area of the base + lateral surface area

=(43+129) cm squared

=172 cm squared

At the farmer's market, there is a scale that measures the weight of fruit and vegetables. The needle is 16 cm long, and it rota

Eddi Din [679]

It may help to draw a picture as you start planning this problem and draw a circle, showing a circle which represents the scale needle's range of motion 360 degrees around. The needle length will then be the radius of that circle.

We know that the needle rotated 68 degrees and are trying to find the distance it traveled in cm. To find out how far the needle traveled, we need to find the arc length - in this case, the distance between the needle's starting point and where it ended up after the oranges were placed on the scale on the circle.

There is a formula you can easily use to find the arc length
arc length = 2* $\pi$ *r ( $\frac{c}{360}$ )

We need to input the radius, r into this formula, as well as the central angle measure c, which in this case is 68 degrees.

2 $\pi$ (16) ( $\frac{68}{360}$ )

If you multiply the above formula components all together using a calculator, you will get ~18.99. (When rounded to the second decimal place.)

So, the answer is around 19 cm. (Your answer may vary depending on how your teacher usually wants you to round answers.)
