Answer:
5.17
Step-by-step explanation:
just at 10 pecent
Since 27 times 9 = 243
Therefore, there are 243 cookies in each case
Answer:
The correct option is;
After 64 seconds, ABOUT HALF of the brands of milk chocolate ARE LIKELY to melt, and NONE of the brands of dark chocolate ARE LIKELY to melt
Step-by-step explanation:
Here we have for the milk chocolate
Min = 29 s
Lower quartile Q₁ = 44 s
Median = 64 s
Upper quartile Q₂ = 93 s
Max = 129 s
For the dark chocolate
Min = 210 s
Lower quartile Q₁ = 237 s
Median = 259 s
Upper quartile Q₂ = 295 s
Max = 320 s
As seen from the values of the box plot, after the median time of 64 seconds which represents half of the test results of the milk chocolate about half of the brands of milk chocolate are likely to melt, while the dark brands only start to melt after 210 seconds.
Therefore the correct option is
After 64 seconds, ABOUT HALF of the brands of milk chocolate ARE LIKELY to melt, and NONE of the brands of dark chocolate ARE LIKELY to melt.
Keywords:
<em>Function, variable, total cost, percentage, jeans
</em>
For this case we have a function of the form
, where 
represents the total cost of buying a pair of jeans, considering that they are 20% below the regular price given by the variable x.
So, if the pair of jeans costs x, we look for 20% of x.
x -----------> 100%
? -----------> 20%
Where "?" represents 20% of x. So, we have:
Thus, 0.2x represents the reduction of the total cost of the pair of jeans
Then, the function that gives the total cost of the pair of jeans, with a reduction of 20% is:
Answer:
Option C
Answer:
x = 1, y = 4
Step-by-step explanation:
This is very simple
Since you have 2 equations with the same coefficient of x, just minus one equation from another:
x + 3y = 13
-
x + 2y = 9
1y = 4
Sub y = 4 into any of the 2 equation,
x + 3(4) = 13
x + 12 = 13
x = 13 - 12
= 1
