Given that Sara put 7 boxes in her closet.
So number of boxes = 7
Then it says that each box is for holding a different type of seashell. So far, there are 0 shells in each box.
So the number of seashell in 1 box = 0
We need to find about how many shells does Sara have.
To find that we will just multiply (number of boxes) by (number of seashell in 1 box). Which is given by 7 times 0.
we know that product of a number and 0 is always 0.
Hence final answer is 0 seashell.
We can use the distribution method for both sides:
9 (x+2) = 5 - 2( x - 1 )
9x + 18 = 5 -2x + 2
Move like terms to one side and combine:
9x + 2x = 5+2-18.
11x = -11
x = -1.
Answer:
D. 16 inches by 8 inches
Step-by-step explanation:
We have been given an image of two rectangles and we are asked to find the dimensions of the enlarged rectangle.
Since we have been given that the original rectangle is enlarged b a scale factor of 4, so to find the dimensions of enlarged rectangle we will multiply the dimensions of original rectangle by 4.
Therefore, the dimensions of enlarged rectangle are 16 inches by 8 inches and option D is the correct choice.
Each truck weighs five tons.
1st truck: n
2nd truck: n + 2
3rd truck: n + 4
4th truck: n + 6
n + n + 2 + n + 4 + n + 6 = 32
4n + 12 = 32
- 12 - 12
--------------------
4n = 20

Answer:
Step-by-step explanation:
Given that in a study of a weight loss program, 4 subjects lost an average of 48 lbs.
It is found that there is about a 32% chance of getting such results with a diet that has no effect.
The results do not appear to have statistical significance. The reasons are
1) Sample size of 4 is very small not even meeting the bare minimum
2) Sample of 4 cannot be taken to represent the population
3) Whether bias was there in the selection of sample is not known.
4) Std deviation is not considered which is very important while concluding results.
