Aging workers of the Neotropical termite, Neocapritermes taracua, develop blue crystal containing glands ("backpacks") on their backs, When they fight intruding termites and are hampered, these "blue" termites explode, and the glands spew a sticky liquid (Sobotnik et al. 2012). The following data are from an experiment that measured the toxicity of the blue substance. A single drop of the liquid extracted from blue termites was placed on individuals of a second termite species, Labiotermes labralis, and the number that were immobilized (dead or paralyzed) within 60 minutes was recorded. The frequency of this outcome was compared with a control treatment in which liquid from glands of "white" termites lacking the blue crystals was dropped instead.
Is the blue liquid toxic compared to liquid from white termites?
Liquid source Unharmed Immobilized
Blue workers 3 37
White workers 31 9
Answers
Answer:
Yes blue liquid is toxic
Step-by-step explanation:
H0: p1 = p2
H1: p1>p2
For blue
We calculate proportion as
37/40 = 0.925
For white
9/40 = 0.2250
To get p
(X1 + x2)/(n1 + n2)
= 0.5750
After calculating the z as statistic (please check attachment) I got 6.33
P value = 0.0000
We reject null hypothesis and say in conclusion that enough evidence exists for us to say blu liquid is toxic!

Use the personal tax per capita in a sentence explaining what this value means. 4 points
Answers
Answer:
Step-by-step explanation:
a. The personal tax collected for 2019 is $103.0 billion.
The tax in scientific notation = $1.03 x [tex]10^{11}[/tex]
b. The population in California is 39.50 million people.
The population in scientific notation = 3.95 x [tex]10^{7}[/tex]
c. Assuming that the whole population of people in Califonia are working i.e employed, the the Personal Tax Per Capita can be determined by;
Personal Tax Per Capita = [tex]\frac{income tax revenue}{taxable population}[/tex]
= [tex]\frac{103000000000}{39500000}[/tex]
= 2607.595
= 2.61 x [tex]10^{3}[/tex]
= 3.00 x [tex]10^{3}[/tex]
d. Therefore provided that the whole population of people in California for 2019 are employed, then each person pays an average of $2607.595 per annum in the year 2019.

D
or
It is shifted 2 units up and 2 units right.
Step-by-step explanation:
The graph of y = sec(x) is shifted 2 units up and 2 units right.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given graph is y = sec(x)
After transformation it is y = sec(x - 2) + 2
We need to find the transformation applied to y=secx to get y = sec(x - 2) + 2.
Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph.
y=f(x-a) is the same graph shifted 'a' units to the right. If 'a' is negative, then, the graph is shifted to the left.
y = f(x) - a is the same graph, but shifted 'a' units downwards. If 'a' is negative, then the graph will be shifted upwards.
In this case, our main function is y=sec(x). And the function y= sec(x-2)+2 is shifted two units to the right and 2 units upwards.
Hence, the graph of y = sec(x) is shifted 2 units up and 2 units right.

A researcher wanted to determine the prevalence of type 2 diabetes among persons living with HIV in Ojai, a small town in California. He developed a survey questionnaire and mailed to 600 residents of Ojai. The survey asked participants several questions including whether their doctor or health care professional ever told them that they had diabetes. All 600 residents completed the survey and the researcher considered their sample a random sample of the 2,500 total residents of 3 Ojai. The following data was compiled from the survey. The prevalence of diabetes in the sampled survey was 6%. The researcher wanted to compare the prevalence of diabetes by smoking status. In their survey, they found that among 230, who were smokers, 157 reported diabetes and among the remaining nonsmokers, 50 reported diabetes.

Given that:
There are 600 residents in the survey.
And results gathered identify that among 230 who were smokers, 157 are reported to have diabetes and among the remaining nonsmokers, 50 reported diabetes.
The objective is to construct a two by two table from the given data:

It is expected that 22,175 units will be sold at a price of $170 a unit. Maximum sales within the relevant range are 27,500 units.
Answers
Answer:
Giving the following information:
Units sold= 450,000
Total Sales= $12,150,000
Total variable cost= $6,925,500
Total fixed cost= $3,242,673
First, we need to calculate the unitary selling price and variable cost. Then, we calculate the contribution margin.
Selling price= 12,150,000/450,000= $27
Unitary variable cost= 6,925,500/450,000= $15.39
Contribution margin per unit= 27 - 15.39= $11.61
To calculate the contribution margin ratio, we need to use the following formula:
Contribution margin ratio= contribution margin/ selling price
Contribution margin ratio= 11.61/27
Contribution margin ratio= 0.43
To calculate the break-even point both in units and dollars, we need to use the following formulas:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 3,242,673 / 11.61= 279,300 units
Break-even point (dollars)= fixed costs/ contribution margin ratio
Break-even point (dollars)= 3,242,673/0.43= $7,541,100
Finally, we need to incorporate the desired profit to the break-even point formula:
Break-even point in units= (3,242,673 + 426,087) / 11.61
Break-even point in units= 316,000 units

7x - 12x - 5 = -45 + 15
How do I solve this please provide an explanation
Answers
Answer:
x = 5 (check steps below)
Step-by-step explanation:
first off lets combine like terms to make it simple so subtract 7x and 12x which comes out to be -5x and add -45 and 15 on the other side which equals -30 so we end up with
-5x -5 = -30
Now we add 5 onto the other side
-5x = -25
finally we divide by -5 on each side to have x by itself
x = 5
