Answer: Hello there!

First, i think that the equation given is 1.6x10^2

Now we need to find a number that is three hundred thousand bigger than this:

This is 300,000 times 1.6x10^2 or 300000*1.6x10^2 = (3x10^5)*(1.6x10^2) = (3*1.6)x10^(5 + 2) = 4.8x10^7

then the number 4.8x10^7 is three hundred thousand times larger than 1.6*102.

First solve the equation
so 163.2
then multiply by 3000
so 489600

iragen [17]

Answer: 8000

Step-by-step explanation:

From the question, we are informed that the expression 10³ × 2^w models the population of the bacteria after w weeks.

The number of bacteria that will be present in 3 weeks will then be:

= 10³ × 2^w

= 10³ × 2³

= 1000 × 8

= 8000 bacterias

Hatshy [7]

Answer:

The proportion of college students who work​ year-round is 58%.

Step-by-step explanation:

The claim made by the education researcher is that 58​% of college students work​ year-round.

A random sample of 400 college​ students, 232 say they work​ year-round.

To test the researcher's claim use a one-proportion <em>z</em>-test.

The hypothesis can be defined as follows:

<em>H</em>₀: The proportion of college students who work​ year-round is 58%, i.e. <em>p</em> = 0.58.

<em>Hₐ</em>: The proportion of college students who work​ year-round is 58%, i.e. <em>p</em> ≠ 0.58. C

Compute the sample proportion as follows:

 \hat p=\frac{232}{400}=0.58

Compute the test statistic value as follows:

 z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}=\frac{0.58-0.58}{\sqrt{\frac{0.58(1-0.58)}{400}}}=0

The test statistic value is 0.

Decision rule:

If the p-value of the test is less than the significance level then the null hypothesis will be rejected.

Compute the p-value for the two-tailed test as follows:

 p-value=2\times P(z

*Use a z-table for the probability.

The p-value of the test is 1.

The p-value of the test is very large when compared to the significance level.

The null hypothesis will not be rejected.

Thus, it can be concluded that the proportion of college students who work​ year-round is 58%.
