The correct option is (B) 77 percent.

Based on data in the table, in 77 percent of colonies with colony collapse disorder were the honeybees infected by all four pathogens.

<h3>What does colony collapse disorder do to bees?</h3>

The adult bees' ability to navigate appears to be affected by the colony collapse disorder. In search of pollen, they depart the hive and never come back. The hive typically contains honey and pollen, as well as signs of recent brood raising. The queen and a few other surviving bees may occasionally stay in the brood nest.

According to the table, all four viruses were present in 77 percent of the honeybee colonies suffering from colony collapse disorder.

Answer:

a) For this case we can use the following R code to construct the qq plot

> data<-c(28.8, 24.4, 30.1, 25.6, 26.4, 23.9, 22.1, 22.5, 27.6, 28.1, 20.8, 27.7, 24.4, 25.1, 24.6, 26.3, 28.2, 22.2, 26.3, 24.4)

# The above line is in order to store the data in a vector

> qqnorm(data, pch = 1, frame = FALSE)

# The line above is in order to calculate the quantiles from the data assumin Normal distribution

> qqline(data, col = "steelblue", lwd = 2)

# The line above is in order to put a line for the theoretical dsitribution

The result is on the figure attached.

b) For this case as we can see on the figure attached the calculated quantiles are not far from the theorical quantiles given byt the straaigth blue line so then we can conclude that the distribution seems to be normal.

Step-by-step explanation:

For this case we have the following data:

28.8, 24.4, 30.1, 25.6, 26.4, 23.9, 22.1, 22.5, 27.6, 28.1, 20.8, 27.7, 24.4, 25.1, 24.6, 26.3, 28.2, 22.2, 26.3, 24.4

The quantile-quantile or q-q plot is a graphical procedure in order to check the validity of a distributional assumption for a data set. We just need to calculate "the theoretically expected value for each data point based on the distribution in question".

If the values are asusted to the assumed distribution, we will see that "the points on the q-q plot will fall approximately on a straight line"

For this case our distribution assumed is normal.

Part a

For this case we can use the following R code to construct the qq plot

> data<-c(28.8, 24.4, 30.1, 25.6, 26.4, 23.9, 22.1, 22.5, 27.6, 28.1, 20.8, 27.7, 24.4, 25.1, 24.6, 26.3, 28.2, 22.2, 26.3, 24.4)

# The above line is in order to store the data in a vector

> qqnorm(data, pch = 1, frame = FALSE)

# The line above is in order to calculate the quantiles from the data assuming Normal distribution (0,1)

> qqline(data, col = "steelblue", lwd = 2)

# The line above is in order to put a line for the theoretical distribution

The result is on the figure attached.

Part b

For this case as we can see on the figure attached the calculated quantiles are not far from the theorical quantiles given byt the straaigth blue line so then we can conclude that the distribution seems to be normal.

What statement makes the open sentence 3x+9=24 true? A. X=3 B. X=5 C.X=11 D.X=15

tatyana61 [14]

The answer would be B) x=5 because 3 times 5 = 15 then add 9 to get 24.

Create a proportion using the form %/100 = is/of to represent the following word problem. 15 is 1 1/2% of what number?

Tema [17]

Let the required number be x, then to create a proportion using the form
$\frac{\%}{100} = \frac{is}{of}$

Thus, let 15 be $1 \frac{1}{2} \%$ of x, then
$\frac{1 \frac{1}{2}}{100} = \frac{15}{x} \\ \\ \frac{ \frac{3}{2} }{100} =\frac{15}{x} \\ \\ \frac{3}{2}x=1,500 \\ \\ x= \frac{1,500\times2}{3} =1,000$

Therefore, 15 is <span> $1 \frac{1}{2} \%$ of</span> 1,000
