Answer:

x = 4 $\sqrt{2}$

Step-by-step explanation:

note the exact value of tan60° = $\sqrt{3}$

Since the triangle is right use the tangent ratio to find x

tan60° = $\frac{opposite}{adjacent}$ = $\frac{4\sqrt{6} }{x}$

multiply both sides by x

x × $\sqrt{3}$ = 4 $\sqrt{6}$

divide both sides by $\sqrt{3}$

x = $\frac{4\sqrt{6} }{\sqrt{3} }$ = 4 × $\sqrt{\frac{6}{3} }$ = 4 $\sqrt{2}$

Novosadov [1.4K]

Using binomial distrubution,
p=0.30
$P(X=x) = C(n,x)p^x (1-p)^{n-x}$
where
$C(n,x)=\frac{n!}{x!(n-x)!}$

(1) exactly x=5 customers out of n=6 make purchase
$P(X=x)=C(n,x)p^x (1-p)^{n-x}$
$P(X=5)=C(6,5)(0.3)^5 (0.7)^{6-5}$
$=6*0.00243*0.7$
$=0.10206$

(2) at least three customers make a purchase
$P(X\ge 3)=\sum_{i=3}^{6}C(6,i)(0.3)^i (1-0.3)^{6-i}$
=0.185220+0.059535+0.010206+0.000729=0.255690
(3) Two or less customers make purchase
Similarly, using binomial distribution
$P(X\le2)=\sum_{i=3}^{6}C(6,i)(0.3)^i(1-0.3)^{6-i}$
=0.117649+0.302526+0.324135
=0.744310

In fact, we do not need to use the binomial distribution to find the answer.
From results in (2), we have
P(X<=2)=1-P(X>=3)=1-0.255690=0.744310

(4) At least one customer makes a purchase
Use the same formulas above for P(X>=1)
Here we will just use
P(X>=1)
= 1- P(X<1)
= 1-P(X=0)
$1-P(X=0)=1-C(6,0)(0.3)^0 (1-0.3)^{6-0}$
=1-0.117649
=0.882351

natali 33 [55]

The percent of the area covered by the first sea is covered by the second is approximately 51.43%. To solve this, you simply divide the area of the first sea (70 million) by the area of the second (36 million). This looks like this: 36000000/70000000. To simplify, you use the ratio 36/70, which will get you the same answer.

Need help asap, need to find x, y, z

Zarrin [17]

Step-by-step explanation:

( 8x - 7 ) + (3x -11 ) = 180 internal angle between 2 parallel lines

so x = 18

2Y + 23 = 4Y + 8 Alternate angle between 2 parallel lines

so y = 15/2

2y + 23 + 3 sq(z) -5 = 180 supplementary angle

Sub y = 15/2 into the above equation

sq(z) = sqr(152/3)

The grid lines will help you find an exact solution (assuming the two lines actually cross at a grid intersection point). However, the two lines may intersect somewhere off the grid lines which is when an estimation will be the next best thing.
