Answer:

13.5

Step-by-step explanation:  

Given: Patrick’s drawing uses a scale of 1 inch = 10 meters. Squidward made another scale drawing of the hotel with a scale of 2 cm = 40 meters.  

To find: How tall is the hotel on Squidward’s drawing?  

Formula: Height of the building = y × tan x + measurer's height  

Solution: The height of the building is calculated by using the formula. y = distance of the measurer from the building. x = the angle measured from the clinometer.

Answer:

10 m building in Patrick's drawing would be of  0.5 cm

Step-by-step explanation:

Scale of Patrick's drawing is

1 inch = 10 meters

or 2.54 cm = 10 meters

1 cm = 3.94 m

In case of  Squidward the scale is 2 cm = 40 meters or

1 cm = 20 meters

So a 10 m building in Patrick's drawing would be of

0.5 cm

Here is a simple probability model for multiple-choice tests. Suppose that each student has probability p of correctly answering
Alla [95]

Answer:

a) The probability that Jodi scores 78% or lower on a 100-question test is 4%.

b) The probability that Jodi scores 78% or lower on a 250-question test is 0.023%.

Step-by-step explanation:

a) To approximate this distribution we have to calculate the mean and the standard distribution.

The mean is the proportion p=0.85.

The standard deviation can be calculates as:

\sigma=\sqrt{\frac{p(1-p)}{n} }= \sqrt{\frac{0.85*(1-0.85)}{100} }=0.04

To calculate the probability that Jodi scores 78% or less on a 100-question test, we first calculate the z-value:

z=\frac{p-p_0}{\sigma} =\frac{0.78-0.85}{0.04} =-1.75

The probability for this value of z is

P(x

The probability that Jodi scores 78% or lower on a 100-question test is 4%.

b) In this case, the number of questions is 250, so the standard deviation needs to be calculated again:

\sigma=\sqrt{\frac{p(1-p)}{n} }= \sqrt{\frac{0.85*(1-0.85)}{250} }=0.02

To calculate the probability that Jodi scores 78% or less on a 250-question test, we first calculate the z-value:

z=\frac{p-p_0}{\sigma} =\frac{0.78-0.85}{0.02} =-3.5

The probability for this value of z is

P(x

The probability that Jodi scores 78% or lower on a 250-question test is 0.023%.

Solve problem A and B please!!
Nana76 [90]

Answer:

a. Isosceles + Acute

b. Scalene + Right

Step-by-step explanation:

a. The side markers show that 2 sides are equivalent in length, making it isosceles. The angles are all noticeably under 90 degrees, resulting in it being acute.

b. There are no side markers whatsoever, making it scalene. There is a right angle marker, resulting in the triangle being right.
