Answer:

k = 6

Step-by-step explanation:

Since the figures are similar, we can use ratios to solve

4 28

----- = -------

k 42

Using cross products

4 * 42 = 28k

Divide each side by 28

4*42/28 = 28k/28

6 = k

Answer: k = 6mm

Step-by-step explanation:

The shapes are similar, which means that each side on the triangle is proportionally similar to its corresponding side on the other triangle.

We can use proportions to solve for k:

$\frac{4}{28} = \frac{k}{42}$

4 and k are proportionally similar and 28 and 42 are proportionally similar.

You can then cross-multiply to get this:

28k = 168

k = 6

The missing side is 6 mm long.

A dish has 212 bacteria in it. The population of the bacteria will grow ata rate of 80% every 2 days. How many bacteria will be

mr_godi [17]

If they are growing 80% for every twodays, it would be 40% for every one day.

Bacteria after 9 days = 212 * 9 * 40 / 100
= 763.2
To round up, the population of bacteria after 9 days would be 763, with a growth rate of 80% for every two days.

As an aid to the establishment of personnel requirements, the director of a hospital wishes to estimate the mean number of peopl

erma4kov [3.2K]

Answer: 24.9793

Step-by-step explanation:

Given : The director randomly selects 64 different 24-hour periods and determines the number of admissions for each.

For this sample, he calculated a mean $\overlien{x}=396$ and a standard deviation of 100.

The 95% confidence interval results in an interval of $396 \pm 24.9793$

We know that the confidence interval for population mean is given by :_

$\overlien{x}\pm E$ , where E is the margin of error.

By comparing this to the given interval , we find that the margin of error = 24.9793

Can someone help me? And no, I don’t just want the answer. I literally need to know how to do it pls

elena-s [515]

Answer:

Step-by-step explanation:

The angle b is a right angle which is divided into 2. So, each angle would measure 45 degree. (90 / 2 = 45)

tan 45 = 1

\AD\ = 100 - 64 = 36

to find x , remember SOCAHTOA

tan would be used because we have the vale of the opposite angle and we want to find the value of the adjacent angle

Tan 45 = opposite / adjacent

1 = 36/x

x = 36
