Answer:

A. <u>P = 1.7% (rounding to the next tenth) </u>

B. <u>P = 33.3% (rounding to the next tenth) </u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of red cards = 20

Number of blue cards = 20

Number of green cards = 20

Total number of cards = 60

2. A. What is the probability that a randomly selected card will be Green 1?

Let's recall that the formula of the probability is:

P = Number of favorable outcomes/Total number of possible outcomes

Replacing with the value we have:

P = 1/60 = 0.017

<u>P = 1.7% (rounding to the next tenth) </u>

B. What is the probability that a randomly selected card will be red?

P = Number of favorable outcomes/Total number of possible outcomes

Replacing with the value we have:

P = 20/60 = 0.333

<u>P = 33.3% (rounding to the next tenth)</u>

Let $x$ be the amount of the 30% alloy and $y$ the amount of the 60% alloy the metalworker will use. However much is used, the final alloy will have a mass of

$x+y=100$

kilograms. For each kg of the 30% alloy used, 0.3 kg is copper; similary, each kg of the 60% alloy contributes 0.6 kg, so that

$0.3x+0.6y=0.54(x+y)=54$

Now,

$x+y=100\implies y=100-x$

$\implies0.3x+0.6(100-x)=54$

$\implies60-0.3x=54$

$\implies0.3x=6$

$\implies x=20$

$\implies y=100-20=80$

Cos(0)=square root 3/3, sin 0<0. what is the value of sin0

abruzzese [7]

Answer:

sin θ = $\frac{\sqrt{6} }{3}$

Step-by-step explanation:

Given that,

cos θ = $\frac{\sqrt{3} }{3}$

From the trigonometric functions,

cos θ = $\frac{adjacent}{hypotenus}$

⇒ adjacent = $\sqrt{3}$ , and the hypotenuse = 3

Let the opposite side be represented by x, applying the Pythagoras theorem we have;

$/hyp/^{2}$ = $/adj/^{2}$ + $/opp/^{2}$

$/3/^{2}$ = $(\sqrt{3} )^{2}$ + $x^{2}$

9 = 3 + $x^{2}$

$x^{2}$ = 9 - 3

= 6

x = $\sqrt{6}$

Thus, opposite side = $\sqrt{6}$

So that,

sin θ = $\frac{opposite}{hypotenuse}$

= $\frac{\sqrt{6} }{3}$

Therefore,

sin θ = $\frac{\sqrt{6} }{3}$

Analyze the set below and complete the instructions that follow.

IrinaVladis [17]

Answer:

C

Step-by-step explanation:

Given: the set is defined as $C=\left \{ x|x$

To find: Set builder form of the complement of the set C.

Solution:

A set is a well-defined collection of objects. Set-builder form is used to denote the elements of the set. This form can also be used to express sets using an interval or an equation.

Complement of set A refers to elements not in A.

For $C=\left \{ x|x$ ,

$C^c=\left \{ x|x\geq -42 \right \}$

Option C is correct.
