Find the value of each variable help fast

Leviafan [203]

Answer:

$a=10\sqrt{3}\ units$ , $b=5\sqrt{3}\ units$ , $c=15\ units$ , $d=5\ units$

Step-by-step explanation:

see the attached figure with letters to better understand the problem

step 1

Find the value of b

In the right triangle BCD

$sin(60\°)=\frac{b}{10}$

$b=sin(60\°)(10)$

Remember that

$sin(60\°)=\frac{\sqrt{3}}{2}$

$b=\frac{\sqrt{3}}{2}(10)$

$b=5\sqrt{3}\ units$

step 2

Find the value of d

In the right triangle BCD

$cos(60\°)=\frac{d}{10}$

$d=cos(60\°)(10)$

Remember that

$cos(60\°)=\frac{1}{2}$

$d=\frac{1}{2}(10)$

$d=5\ units$

step 3

Find the value of a

In the right triangle ABD

$sin(30\°)=\frac{b}{a}$

$a=\frac{b}{sin(30\°)}$

Remember that

$sin(30\°)=\frac{1}{2}$

$b=5\sqrt{3}\ units$

$a=\frac{5\sqrt{3}}{(1/2)}$

$a=10\sqrt{3}\ units$

step 4

Find the value of c

In the right triangle ABD

$cos(30\°)=\frac{c}{a}$

$c=(a)cos(30\°)$

Remember that

$cos(30\°)=\frac{\sqrt{3}}{2}$

$a=10\sqrt{3}\ units$

substitute

$c=(10\sqrt{3})\frac{\sqrt{3}}{2}$

$c=15\ units$

therefore

$a=10\sqrt{3}\ units$

$b=5\sqrt{3}\ units$

$c=15\ units$

$d=5\ units$

Julli [10]

Answer:

A) 0.335; B) 0.343; C) 0.599

Step-by-step explanation:

For part A,

To find the probability that the user has more than one infection per year, we can either add together the probabilities for 2, 3, 4 and 5; or we can add together the probabilities for 0 and 1 and subtract them from 1:

1-(P(X = 0)+P(X = 1))

= 1-(0.343+0.322) = 1-0.665 = 0.335

For part B,

The probability that the user has no infections per year is P(X = 0); this is 0.343.

For part C,

The probability that the user has between 1 and 3 infections (inclusive) per year is

P(1 ≤ X ≤ 3) = 0.322+0.201+0.076 = 0.599

I think 45 because if you look at the top of the other 45 the graphs look the same lengths except this one stretches out so 45°
