Why do we divide by 4

1 answer:

5 0

This kind of question would actually be very dependable. So, let's suppose that we would have a number as 16. We would then have to divide this number by 4, mainly because we would want to find how many 4's would go into the number 16. But this would actually be an example. So, whatever math problem you may have, just remember this technique, how many numbers would go into that specific number.

Step-by-step explanation:

Since PT = 2PM and AR = 2AD,

The midsegment MD must be the average of PA and TR:

Therefore we have

2(20x + 4) = 10 + (34x + 16)

=> 40x + 8 = 34x + 26

=> 6x = 18

=> x = 3

Hence length of MD

= 40(3) + 8 = 128.

The seasonal output of a new experimental strain of pepper plants was carefully weighed. The mean weight per plant is 15.0 pound

Answer:

There are 118 plants that weight between 13 and 16 pounds

Step-by-step explanation:

For any normal random variable X with mean μ and standard deviation σ : X ~ Normal(μ, σ)

This can be translated into standard normal units by :

$Z = \frac{(X - \mu)}{\sigma}$

Let X be the weight of the plant

X ~ Normal( 15 , 1.75 )

To find : P( 13 < X < 16 )

$= P(\frac{( 13 - 15 )}{1.75} < Z < \frac{( 16 - 15 )}{1.75})$

= P( -1.142857 < Z < 0.5714286 )

= P( Z < 0.5714286 ) - P( Z < -1.142857 )

= 0.7161454 - 0.1265490

= 0.5895965

So, the probability that any one of the plants weights between 13 and 16 pounds is 0.5895965

Hence, The expected number of plants out of 200 that will weight between 13 and 16 = 0.5895965 × 200

= 117.9193

Therefore, There are 118 plants that weight between 13 and 16 pounds.
