Answer:

Yes, Amanda has enough materials to make the concrete mix.

Step-by-step explanation:

Total units = 1+3+5

= 9

9 units = 630kg

1 unit = 630kg ÷ 9

= 70kg (Less than 80kg of cement, more than enough)

3 units = 3 × 70kg

= 210kg (Less than 215kg of sand, more than enough sand)

5 units = 5 × 70kg

= 350kg (Less than 370kg of gravel, more than enough gravel)

2x=45-3xs simplify?

Lelu [443]

2x=45-3xs

1. Add 3xs to both sides

2x+3xs=45

2. Factor out the common term X

X(2+3s)=45

3. Divide both sides by 2+3s

X= 45/2+3s

A random variable x takes four possible values, 0, 2, a, and b, where a and b are unknown numbers. if pr[x = 0] = 0.2, pr[x=2] =

Alexus [3.1K]

$\displaystyle\sum_{x\in\{0,2,a,b\}}\mathbb P(X=x)=1$
$\mathbb P(X=0)+\mathbb P(X=2)+\mathbb P(X=a)+\mathbb P(X=b)=1$
$0.2+0.4+0.3+\mathbb P(X=b)=1$
$\implies\mathbb P(X=b)=0.1$

$\mathbb E(X)=\displaystyle\sum_{x\in\{0,2,a,b\}}x\mathbb P(X=x)=2.8$
$0\mathbb P(X=0)+2\mathbb P(X=2)+a\mathbb P(X=a)+b\mathbb P(X=b)=2.8$
$0.8+0.3a+0.1b=2.8$
$0.3a+0.1b=2$

$a+b=6\implies0.3a+0.1b=0.2a+0.1(6)=2$
$0.2a+0.6=2\implies0.2a=1.4\implies a=7$
