A rhombus is quadrilateral where all 4 sides are of equal length. Thus


5x + 2 = 2x + 12

3x = 10

x = 10/3

substituting x into either expression, yields

56/3

therefore side AB = 56/3

It has been estimated that only about 30% of California residents have adequate earthquake supplies. Suppose you randomly survey
mote1985 [20]

Answer:

P(X\geq 8)=0.0043\\\\

It's more likely that  all of the residents surveyed will have adequate earthquake supplies since it has a probability of 98.02% which is very close to 100%.

Step-by-step explanation:

-This is a binomial probability problem with the function:

P(X=x)={n\choose x}p^x(1-p)^{n-x}

-Given p=0.3, n=11, the is calculated as:

P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X\geq 8)=P(X=8)+P(X=9)+P(X=10)+P(X=11)\\\\={11\choose 8}0.3^8(0.7)^3+{11\choose 9}0.3^9(0.7)^2+{11\choose 10}0.3^{10}(0.7)^1+{11\choose 11}0.3^{11}(0.7)^0\\\\=0.0037+0.0005+0.00005+0.000002\\\\=0.0043

Hence, the probability that at least 8 have adequate supplies 0.0043

#The probability that non has adequate supplies is calculated as;

P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X= 0)={11\choose 0}0.3^{0}(0.7)^{11}\\\\=0.0198

#The probability that all have adequate supplies is calculated as:

P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X= All)=1-{11\choose 0}0.3^{0}(0.7)^{11}\\\\=1-0.0198\\\\=0.9802

Hence, it's more likely that  all of the residents surveyed will have adequate earthquake supplies since P(All)>P(None)\ \ and that this probability is 0.9802 or 98.02% a figure close to 1
