Answer:

B. 3.6 x 10^3

Step-by-step explanation:

(1.2 x 10^-2) x (3 x 10^5)

When we multiply terms with powers , we multiply the factors out front and add the exponents

a * 10^b  * c* 10^d = ac * 10^(b+d)

(1.2 x 10^-2) x (3 x 10^5)   = (1.2* 3) * 10^(-2+5)

                                         = 3.6 * 10 ^3

Weight of a rock: In a geology course, students are learning to use a balance scale to accurately weigh rocks. One student plans
vladimir2022 [97]

Answer:

We are 95% confident that the true weight of the rock is between 25.2 g and 29.1 g.

Step-by-step explanation:

Hello!

A geology student weighted a rock 5 times and estimated the average weight using a 95% CI [25.2; 29.1]gr

The confidence interval is used to estimate the value of the population mean, it gives you a range of values for it.

The 95% level of confidence of the interval indicates that if you were to construct 100 confidence intervals to estimate the population mean, you'd expect 95 of them to include the true value of the parameter.

So with a 95% confidence level, you'd expect the true average weight of the rock to be included in the interval  [25.2; 29.1]gr

I hope this helps!

The yard care staff can mow 45 lawns in a 10-hour work day. Each of the 9 workers can mow the same number of lawns per hour. How
kompoz [17]

If it takes 10 hours for 9 workers to mow 45 lawns, dividing the 45 lawns by 9 we see that in 10 hours one worker can mow 5 lawns. This means that in one hour, a single worker can mow 5/10=1/2 of a lawn

Can someone plz help me
Vanyuwa [196]

Answer:

C

Step-by-step explanation:

Notice how the angles look the same, but if we look at the base of our second house, it's value is triple that of the first house. Therefore, we can infer that the other values must be triple the size, as well. Thus, multiplying our values of the first house, we get answer C!

Hope this helped!
