For the rectangle: l x w = Area
l = 18
w = 18
18 x 18 = 324
If 16m is for dash line
1/2bh
1/2(16)(16)
4(16) = 64
1/2bh
1/2(8)16
8(8) = 64
324 + 64 + 64 = 452
Your area should be 452m²
hope this helps

Answer:
D) Neither X nor Y can be well approximated by a normal random variable.
Step-by-step explanation:
X = number of males (out of the 20) who are colorblind.
Y = number of females (out of the 40) who are colorblind.
Z = total number of colorblind individuals in the sample (males and females together).
The condition to use the normal approximation is that np > 5 and nq > 5
For X:
n = 20, p = 8% = 0.08,
q = 1 - 0.08 = 0.92
np = 20 * 0.08
np = 1.6 ( np < 5)
np = 20 * 0.92
np = 18.4 ( nq > 5)
For Y:
n = 40, p = 1% = 0.01,
q = 1 - 0.01 = 0.99
np = 40 * 0.01
np = 0.4 ( np < 5)
np = 40 * 0.99
np = 39.6 ( nq > 5)
For both X and Y, np < 5 and nq > 5. Since both np and nq are not greater than 5, both samples cannot be approximated by a normal distribution.
Answer:
Step-by-step explanation:
A mixed fraction of the form 
can be converted into an improper fraction by writing it in the form 
. By applying this formula , we can see that 
. As numerator is greater than the denominator , we can see that the answer is greater than one and thus it is an improper fraction.
