Answer:

No

If the fraction is an improper fraction, the product would be higher

if the numerator of the fraction is smaller than the denominator, the product would be lower

2 x 3/4 = 3/2 = 1 1/2

2 x 4/3 = 8/3 = 2 2/3

Step-by-step explanation:

an improper fraction is a fraction in which the numerator is greater than the denominator

The numerator is the number above. While the denominator is the number below

an example of a fraction = \frac{4}{5}  

4 is the numerator while 5 is the denominator

In 15 diffret days 15/4 inches of rain fell in April month if every day rained 1/4 of a inch .

How to find the rain fell in 15 diffret days ?

We know that rain in every day is 1/4 of a inch

So for 15 days

1/4+1/4+1/4+......15times\\=15/4

So in 15 diffret days in April rain fell is 15/4 inches.

Answer:

The answer to your question is h = 125.85 ft = 126 ft

Step-by-step explanation:

Process

1.- Determine two equations to solve the problem

    tan 14 = \frac{h}{x}                     (1)

    tan 47 = \frac{h}{x - 386}           (2)

    from (1)                           h = xtan14

    substitute in (2)             tan 47 = \frac{xtan14}{x - 386}

    solve for x                     tan47(x - 386) = xtan14

                                          1.07x - 413.9 = 0.25x

                                          1.07x - 0.25x = 413.9

                                           0.82x = 413.9

                                           x = 413.9/0.82

                                           x = 504.76 ft

2.- Calculate h

                                          h = 504.76 tan 14

                                          h = 125.85 ft = 126 ft

4) Dan Ariely and colleagues have conducted some extremely interesting studies on cheating (see, for example Mazar, Amir, &
lianna [129]

I've attached the complete question.

Answer:

Only participant 1 is not cheating while the rest are cheating.

Because only participant 1 has a z-score that falls within the 95% confidence interval.

Step-by-step explanation:

We are given;

Mean; μ = 3.3

Standard deviation; s = 1

Participant 1: X = 4

Participant 2: X = 6

Participant 3: X = 7

Participant 4: X = 0

Z - score for participant 1:

z = (x - μ)/s

z = (4 - 3.3)/1

z = 0.7

Z-score for participant 2;

z = (6 - 3.3)/1

z = 2.7

Z-score for participant 3;

z = (7 - 3.3)/1

z = 3.7

Z-score for participant 4;

z = (0 - 3.3)/1

z = -3.3

Now from tables, the z-score value for confidence interval of 95% is between -1.96 and 1.96

Now, from all the participants z-score only participant 1 has a z-score that falls within the 95% confidence interval.

Thus, only participant 1 is not cheating while the rest are cheating.
