What are scale drawings? can you give an example?

Mathematics

Alecsey [184]3 years ago

Scale Drawings are drawings that are used to show the true size of something.
Scale drawings are most commonly used in maps, or in large scale drawings. These show the scale of something. It may show that 1cm is equivalent to 1km, which would allow someone to measure the map to see how far the distance it. It also allows a map to be made smaller, and less detailed- making it often easier to read.
Hope this helps :)

What is 10 = 0.860(7) + 3.302
Vesnalui [34]

Hey there!

0.860(17) + 3.302 = 10

= 0.86(17) + 3.302

= 14.62 + 3.302

= 17.922


Thus, your answer is: FALSE because

17.922 ≠ 10


Good luck on your assignment & enjoy your day!

About 1/4 of all adults in the United States have type O+ blood. If three randomly selected adults donate blood, find the probab
valina [46]

Answer:

a) 0.0156

b) 0.4219

c) 0.1406

Step-by-step explanation:

We are given the following information:

We treat adult having type O+ blood as a success.

P(Adult have type O+ blood) = 0.25

Then the number of adults follows a binomial distribution, where

P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 3

a) All three are type O+

P(x =3)\\= \binom{3}{3}(0.25)^3(1-0.25)^0\\= 0.0156

b) None of them is type O+

P(x =0)\\= \binom{3}{0}(0.25)^0(1-0.25)^3\\= 0.4219

c) Two out of the three are type O

P(x =2)\\= \binom{3}{2}(0.25)^2(1-0.25)^1\\= 0.1406

Elana is programming a video game. She needs to simulate the power up that the player gets when they reach a certain level. The
zvonat [6]

Answer:

You have to define when the power should be pushed up using the 'For' statement and let an impulse be sent to the CPU to increase power by 15%

Step-by-step explanation:

We use certain functions in writing computer programs.

For the 'For' statement ; we can define conditions. First Elana would define at what point does she want the player power to get the best power.

For example if she defines that when the player has played for 2hours return an integer 1 for instance.

This value returned will now send a pulse to the CPU to increase its power to 15%.

If the player plays for further 1hour she can define the count to be 10 and so send another pulse to the CPU to increase the processing power by additional 15%
