9514 1404 393

Answer:

1367 people

Step-by-step explanation:

The wording "a rate proportional to the number" indicates the function is exponential. The growth factor is 1200/1000 = 1.2 in 7 days, so the exponential function can be written ...

i(t) = 1000(1.2^(t/7))

After 12 days, the number infected is modeled as ...

i(12) = 1000(1.2^(12/7)) ≈ 1367

About 1367 people are infected 12 days after discovery.

Which expression is equivalent to 24 Superscript one-third?

Ivahew [28]

Answer:

See explanation

Step-by-step explanation:

The given expression is: $(24)^{\frac{1}{3}}$

Recall that 24=3*8

$\implies(24)^{\frac{1}{3}}=(8*3)^{\frac{1}{3}}$

Recall again that:

$(a*b)^n=a^n*b^n$

$\implies (8*3)^{\frac{1}{3}}=(8)^{\frac{1}{3}}*(3)^{\frac{1}{3}}$

$\implies (8*3)^{\frac{1}{3}}=(2^3)^{\frac{1}{3}}*(3)^{\frac{1}{3}}$

$\implies (8*3)^{\frac{1}{3}}=2^{3*\frac{1}{3}}*(3)^{\frac{1}{3}}$

$\implies (8*3)^{\frac{1}{3}}=2*(3)^{\frac{1}{3}}$

We rewrite in radical form to obtain

$\implies (8*3)^{\frac{1}{3}}=2\sqrt[3]{3}$

Determine whether the events are independent (I) or dependent (D). Place your answer in the blank provided. 1. Ramiro draws a ma

Stels [109]

Answer:

Independent events

Step-by-step explanation:

Given that:

Ramiro draws a marble from a jar without replacement and then flips a coin

Let $E_1$ be the event that Ramiro draws a marble without replacement and;

Let $E_2$ be the event of flipping a coin.

Let's have an analogy so that we can better understand the concept of independent and dependent events.

Consider a random experiment in which a marble is drawn from a jar without replacement and a fair coin is flipped together.

The event $E_1$ does not in any way affect the event $E_2$ of a head or a tail showing up in a flip of a coin.

Therefore, we say that $E_1$ and $E_2$ are independent events.

Suppose the event $E_1$ affects or influence the event $E_2$ , then we can say they are dependent events.
