Answer:

(a)Yellow=10

Green=38

Relative Frequency of Blue =0.32

Relative Frequency of Red =0.2

Relative Frequency of Green =0.38

(b)50 Red balls

Step-by-step explanation:

In 100 trials, the following were recorded.

Frequency of Blue Balls = 32

Frequency of Red Balls = 20

Relative Frequency of Yellow Balls =0.1

Now, Relative Frequency =Number of Outcome of an Event ÷ Total Number of Trials in the Experiment

Total Number of Trials =100

Therefore:

Therefore, Number of Outcomes of Green balls=100-(32+20+10)

=100-62

Number of Outcomes of Green balls=38

(b)If the Number of Trials is Increased to 250

Expected Outcome of Red Balls =Relative Frequency of Red Balls X 250

She should expect 50 red balls.

The half-life of Radium-226 is 1590 years. If a sample contains 200 mg, how many mg will remain after 1000 years?
adell [148]

Answer: 129.33 g

Step-by-step explanation:

$$Let $p=A \cdot e^{n t}$ \\$(p=$ present amount, $A=$ initial amount, $n=$ decay rate, $t=$ time)

\begin{aligned}&\Rightarrow \text { Given } p=\frac{A}{2} \ a t  \ t=1590 \\&\Rightarrow \frac{1}{2}=e^{1590n} \Rightarrow n=\frac{\ln (1 / 2)}{1590}=-0.00043594162\end{aligned}

$$If $A=200 \mathrm{mg}$ and $t=1000$ then,$$\begin{aligned}P &=200 e^{\left(\frac{\ln \left(1/2\right)}{1590}\right) \cdot 1000} \text \\\\&=129.33 \text { grams}\end{aligned}$$

Help please!!!!!!!!!!!!! Explain if possible
iris [78.8K]
Answer is C.
For every option, sub in the value and find the answer that matches the equation!

Example for option A, F(x) = x + 4 and G(x) = x²
G(F(x)) = G(x + 4) ーー> sub in the value of F(x)
Let's take the subbed in value, (x + 4) as x, and this x will be the x for G(x).

∴ Since G(x) is x²
G(x + 4) = (x + 4)² ーー> remember (x + 4) is represented as x.
= x² + 16
∴ You know that the answer is not A, do this for all options and you'll find the answer, C!

Solve each pair of simultaneous equations by substitution method
WARRIOR [948]

Answer:

x = 1       y = -4

Step-by-step explanation:

- Plug the value of y into the other equation.

x + 3y = -11

x + 3(-4x) = -11

x - 12x = -11

-11x = -11

x = 1

- Now substitute the value of x into any equation.

y = -4x

y = -4(1)

y = -4
