Answer:

10^4 or 10,000

Step-by-step explanation:

The ratio of pig mass to mouse mass is ...

(2×10^2 kg)/(2×10^-2 kg) = (2/2)×10^(2-(-2)) = 10^4 = 10,000

A pig has about 10^4 times the mass of a mouse.

A rectangle has an area of 112 square units. If its width was half as long and its length was 8 times as long, what would be its new area?

Answers

Area (rectangle)=lenght x width
lenght=x
width=y
xy=112 u²

Then
(y/2)(8x)=4xy
Therefore:
xy=112 u² then 4xy=4(112 u²)=448 u²

answer: the new area would be 448 u²

Answers

1) set up a problem
you know you want to get an avg of 94 but how do you do avg in the first place. you add up the numbers then divde by the total number of numbers used lol

so $(92.5+x)/(2)=94$
92.5 is the avg number for the last 3 tests
"x" is the 4th test score which we want to find out
"2" is the total number of numbers being added together

so now lets get x to one side

92.5+ x=94*2 (multiply 2 to both sides)
92.5+x=188
x=188-92.5 (subtract 92.5 from both sides)
x= 95.5 this is the score she need to make to avg 94%

2) you can draw a tree diagram. for example Flower1 branches off into 3 diff greens and then each of those greens branch off into 2 for with or with babies breath.

or you can simple multiply 4*3*2. you can do this because all choices are included with no restriction

your total number of options is 24

Priya is playing a game where she earns online badges for scoring higher than the mean score on a level. After the tenth level, she scores 3,540 points, which is 2 standard deviations above the mean score of 3,110 points.What is the standard deviation of scores for the tenth level?

a.)215
b.)311
c.)354
d.)430

Answers

If score of 3,540 points is 2 standard deviations above the mean score of 3,110, then:
3,110 + 2 s= 3,540
2 s = 3,540 - 3,110 = 430
s = 430 : 2
s = 215
Answer: A) The standard deviation is 215.

The standard deviation of scores for the tenthlevel is 215 and is denoted as option A.

What is Standard deviation?

This is defined as the measure of the amount of variation or dispersion of a set of values.

We were told that score of 3,540 points is 2 standard deviations above the mean score of 3,110 therefore,

3,110 + 2 s= 3,540

2 s = 3,540 - 3,110

2s = 430

s = 430/2

s = 215
