15 sandwiches
3 tomatoes= 5 sandwiches.
So if there's 9, that makes 3 groups of 3 tomatoes which would make 3x5 or 5+5+5 ;-;
15.
For this question, you can simply multiply the two numbers together to get your answer, which is four. This can also be figured out just by listing the possibilities.
*The first shirt with the first pair of pants
*The first shirt with the second pants
*the second shirt with the first pants
*the second shirt with the second pants
The answer is 4 different outfits
X + y = -10
-3x -y = 2
We'll try with x as a small number and y with a big number to try and balance it out.
-3 - 7 = 10
9 - 7 = 2
X = -3
Y = -7
Hope this helps! :)
Answer: Option A. 1.5
Mean shoe size of the students in a math class: µ=7.5
Standard deviation: σ
Most of the shoe sizes (x) fall within 1 standard deviation:
µ-1σ<x< µ+1σ
µ-σ<x< µ+σ
<span>or between a size 6 and a size 9:
</span>6<x<9
Comparing µ-σ<x< µ+σ with6<x<9:
µ-σ=6 or µ+σ=9
Replacing µ=7.5 above:
7.5-σ=6 or 7.5+σ=9
Solving for σ:
7.5-σ-7.5=6-7.5 or 7.5+σ-7.5=9-7.5
-σ=-1.5 or σ=1.5
σ=1.5 or σ=1.5
Then σ=1.5

Step-by-step explanation:
It is usually convenient to choose small exponents when graphing an exponential function. You can get a reasonable idea of the shape of the curve using x-values with a magnitude of 3 or less.
The exponential term 2^x has a horizontal asymptote of y=0 for large negative values of x. Adding 3 to that term shifts the horizontal asymptote up to y=3. Of course, everything else is shifted up the same amount.
You know that ...
2^-1 = 1/2
2^0 = 1
2^1 = 2
2^2 = 4
Adding 3 to these values will give you points on the graph for x=-1 to 2.
