Answer:
1/21
Step-by-step explanation:
The baker makes 84 loaves of bread,
Out of the 84 bread, 4 of them got burn.
Fraction that the loaves does the burn will be expressed in 4/84 = 1/21.
Answer:
2x + 1y =< 300
x + y =>150 units
y <= 2x
Step-by-step explanation:
Let x and y be the numbers of corndogs and shakes that will be sold.
<u>1.</u> The total cost of making these items is given by the sum of:
(x)(RM2) + (y)(RM1)
A total of RM300 is allocated for the cost of these items, so:
2x + 1y =< 300 [Units are RM)
<u>2.</u> Sales are expected to exceed 150 units, in total. This means:
x + y =>150 units
<u>3.</u> Sales for the shakes is less than 2 times that of the corndogs:
y <= 2x
Answer:
D. There is no association because the distribution of genre preferences is the same among the grade groups
Explanation:
Based on this graph, we can conclude that there is no association between grade and genre preference, because the distribution of genre preferences is the same among the grade groups
.
We can see that the 9th and 11th graders have a slightly higher preference for fiction than the 10th and 12th graders. However, this difference is barely noticeable and doesn't affect the conclusion. Most students from every grade prefer fiction to nonfiction, so we can conclude that the genre preference is the same among the grade groups
.
As it is emphasized above, the area (A) of a square is the square of its sides (l),
A = l²
The area of the square should be 120 ft². Substituting this to the equation,
120 ft² = l²
Solving will give us an answer of l being approximately equal to 10.95 ft.
2n² + n + 1
<u>Explanation:</u>
The sequence is 4, 11, 22, 37
Difference between: 7, 11, 15
The first differences are 7, 11, 15, and the second differences are 4.
Since half of 4 is 2, then the first term will be 2n^2.
Subtracting 2n² from the sequence gives 2, 3, 4, 5 which has nth term n + 1.
Therefore the final answer is 2n² + n + 1
