That would be A :D It would be A because you would do keep change flip. You would keep 5/6, change the division sign to multiplication, then flip the 5/16 to 16/5 (the reciprocal)

Two cross roads ,each width 10m cut at right angle through the centre of a rectangular park of length 700m and breadth 300m and

Dafna11 [192]

Answer:

Step-by-step explanation:

Area of one road = 700 x 10

7000 sq m

area of another road

= 300 x 10 = 3000sq m

Total area of road

= 7000 + 3000 - 10 x 10

= 9900 sq m

Area of park

= 700 x 300

= 210000 sq m

less area of road

= 210000 - 9900

= 200100 sq m

= 200100 / 10000 hectare

= 20.01 hectare.

The length of time needed to complete a certain test is normally distributed with mean 46 minutes and standard deviation 6 minut

madam [21]

Answer:

0.0668 or 6.68%

Step-by-step explanation:

Mean time (μ)= 46 minutes

Standard deviation (σ) = 6 minutes

The z-score for any given time X is determined by:

$z=\frac{X-\mu}{\sigma}$

For X = 37:

$z=\frac{37-46}{6}\\ z=-1.5$

A z-score of -1.5 corresponds to the 6.68th percentile of a normal distribution. The probability that it will take less than 37 minutes to complete the test is

$P(X\leq 37) = 0.0668=6.68\%$

The probability is 0.0668 or 6.68%
