ad-work [718]

Answer:

5 kmph

Step-by-step explanation:

Given: Greg swam 4 kilometers against the current.

Greg swam 16 kilometers with the current.

Rate of the current was 3kmph.

Lets assume the speed of greg swimming with no current be "x".

∴ Speed of swimming against current= $(x-3)\ kmph$

Speed of swimming with current= $(x+3)\ kmph$

As given, it took same amount of time to swim both with current and against current.

∴ Forming an equation to find the value of x, which is speed of greg swimming with no current.

We know, $Time= \frac{Distance}{Speed}$

⇒ $\frac{4}{(x-3)} = \frac{16}{(x+3)}$

Multiplying both side by (x+3) and (x-3)

⇒ $4\times (x+3)= 16\times (x-3)$

Using distributive property of multiplication.

⇒ $4x+12= 16x-48$

Subtracting both side by 4x and adding by 48.

⇒ $60= 12x$

Dividing both side by 12

⇒ $x= \frac{60}{12} = 5\ kmph$

Hence, Greg can swim at the rate of 5kmph with no current.

The data represents the body mass index? (bmi) values for 20 females. construct a frequency distribution beginning with a lower

Reil [10]

Given the data below <span>representing the body mass index (bmi) values for 20 females.
17.7   33.5 26.9 22.7    22.2 29.9 23.6    18.3    27.7 23.4 19.2 25.9 22.9 37.7 31.6    28.1 44.9 31.6 25.2 23.9

From the data above, we construct a frequency distribution beginning with a lower class limit of 15.0 and use a class width of 6.0 as follows:

Class iinterval: 15.0 - 21.0   21.0 - 27.0   27.0 - 33.0   33.0 - 39.0   39.0 - 45.0
Frequency:    3    9    5 2    1

From the frequency table, it can be seen that the frequencies started low, increased to a point and then decrease. It can also be seen that the highest frequency of the data is not at the center of the distribution, so the distribution is not symetric.

Therefore, the frequency distribution does not appear to be roughly a normal distribution, because, "although the frequency start low, increase to some maximum, then decrease, the distribution is not symmetric."</span>
