Consider the 1-to10^19 scale on which the disk of the Milky Way Galaxy fits on a football field. On this scale, how far is it from the sun to the alpa centauri (real distance:4.4 light-years) How big is the sun itself on this scale? Compare the sun's size on this scale to the actual size of a typical atom (about 10^-10 m in diameter).

Answers


a = 2
b = 3.156

   (a + b)  =  (2) + (3.156)  =  5.156
just add if it were normal 2 + 3 = 5 and just out the .156

answer is 5.156

Choose a method the find the product 16x60

Answers

the product is 960 because 0x6=0,6×6=36 so 60 times 6 is 360 thenn you go to the bottom & bring down one zero under your first zero ,multiply 1 times the zero which equals 0 ofc & 6×1=6 so it'll be 360 + 600= 960
The answer is 960 because 16 times 60 is =960

How do i solve exterior angles on triangles (picture)

Answers

remember
the exterior angle=sum of the other 2 interior anlges

therfor
(one that is less pointy triangle)
2x+3x=135
5x=135
x=27
2*27=54
3*27=81
the interior angles are 54 and 81 and x=27


other pointier one with 3x-1 on it
12+3x-1=167
11+3x=167
minus 11
3x=156
divide 3
x=52
sub
3*52=156
156-1=155
missin angle is 155, x=52
attachment below (in degrees)
you recieve exterior angles by adding the degrees

A researcher is using a repeated-measures study to evaluate the difference between two treatments. If the difference between the treatments is consistent from one participant to another, then the data should produce ______. A. a small variance for the difference scores and a small standard error
B. a small variance for the difference scores and a large standard error
C. a large variance for the difference scores and a small standard error
D. a large variance for the difference scores and a large standard error

Answers

Answer:

A) a small variance for the difference scores and a small standard error

Step-by-step explanation:

Since the difference scores are obtained by subtracting one variable form another, if the difference scores are consistent between treatments, then the variance will be small. The higher the variance, the higher the standard error. So if the variance is small, then the standard error will also be small.

Answers

P(Boy) 

= Number of boys/Total number of people

= 7 / (7+3)

=7/10

=0.7

Answer:

7/10 (7 over 10) or 0.7

There are 7 boys and 3 girls, combined they equal to 10. So, the probability of picking a boy is very likely to be chosen because the probability is over 50% (70%).
