The above statement is inferential in its approach.
Step-by-step explanation:
Inferential results are deferred results meaning results are deduced from the above assumptions or survey.
As per the results of the survey, 7.7% of adults in the country owning a digital camera and are in process to replace their camera in the coming 12 months.
This means that the survey formed the basis of the above-made deduction that of all the 7.7% adult who owns a camera is planning to replace it. Hence the statement is inferential in its approach.
Answer:
Step-by-step explanation:
Is this the entire question? Some of it makes no sense without a diagram or something.
To get rid of A you actually have to solve the equation.
7h – 5(3h – 8) = –72 Remove the brackets
7h - 15h + 40 = - 72 Combine the like terms
- 8h + 40 = - 72 Subtract 40 from both sides
- 8h = -112 Divide by -8
h = 14
Well the depth is a whole number so A is true.
We don't know anything about time. But the answer is positive.
C is false because B is true.
We don't know exactly what the depth of the well is.
I would pick A, but you need the entire question.
Answer:
315
Step-by-step explanation:
45/60 = 3/4
3/4 * 420 = 315
Answer:
YES
Step-by-step explanation:
4(Z-3)=16
4Z-12=16
+12 +12
4Z=28
Z=7
Volume of first oil = A, volume of second oil = B, volume of mixture = M
A = ?, B = 4l, M = A + B
40%A + 25%B = 30%M
40%A + 25%4l = 30%(A+4l)
<span>40%A + 25%4l = 30%A + 30%4l
40A + 100l = 30A + 120l
40A - 30 A = 120l - 100l
10A = 20l
A = 2l

Answer: 2 litres of 40% oil dressing.
Also note: That's an approximation, because the volumes are not strictly additive. For example: mixing 50ml pure ethanol with 50ml water will give you about 95ml of mixture. To get an accurate answer, you'd have to measure the volume of the final mixture and then divide your total oil content by that<span>.</span>
