Applications of Probability Project: Zombie Apocalypse Adapted from "Are You Positive?" Learning Task in the Georgia Frameworks Zombies are on the loose! A group of researchers wants to be able to detect those who have contracted the zombie virus before they turn into zombies. Those who test positive will be quarantined for two weeks. If they show no signs of being a zombie, they will be freed. They have developed a simple test where they swab the person's ear (mouth would be too dangerous). They gathered 200 people of which 50 were known to be have the zombie virus. Of those who had the virus, 48 tested positive. Of those who did not have the virus, 135 tested negative 1. Based on the data presented above, do you think the test for zombieism is effective at detecting future zombies. Why or why not?

Answer:

$32.10  

Step-by-step explanation:

The amount to be accumulated in 15 years is the future value of the sinking fund, hence, using the future value formula below, we can determine the required weekly payment as appropriate:

Future value=weekly payment*(1+r)^n-1/r

Future value=$35,000

weekly payment is the unknown

r=weekly interest rate=4.25%/52=0.08173077% ( I use 8 decimal places in order to achieve accuracy)

n=number of weekly payments in 15 years=15*52=780

35000=weekly payment*(1+0.08173077% )^780-1/0.08173077%

35000=weekly payment*(1.89125311 -1)/0.000817308

35000=weekly payment*0.89125311 /0.000817308

weekly payment=35,000*0.000817308 /0.89125311

weekly payment=$32.10

the tenth number in the sequnce is 41.

Answer:

D) 5/2

Step-by-step explanation:

Scale factor = AB/DE = 35/14 = 5/2

The scale factor from ΔABC to Δ DEF is, 5 / 2

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

We have to given that;

The figure of ΔABC to Δ DEF is shown in image.

Now, We can formulate for the scale factor,

⇒ AB / DE

⇒ 35 /14

⇒ 5 / 2

Thus, The scale factor from ΔABC to Δ DEF is, 5 / 2

Answer:

the answer is 15 I'm positive

Answer:

The identity is proved below.

Step-by-step explanation:

The tangent of an angle [tex]\theta[/tex] is given by:

[tex]\tan{\theta} = \frac{\sin{\theta}}{\cos{\theta}}[/tex]

In this question, we are given the following trigonometric identity:

[tex]\frac{\sin{\theta}}{\sin{\theta}+\cos{\theta}} = \frac{\tan{\theta}}{1+\tan{\theta}}[/tex]

Applying the tangent

[tex]\frac{\sin{\theta}}{\sin{\theta}+\cos{\theta}} = \frac{\frac{\sin{\theta}}{\cos{\theta}}}{1+\frac{\sin{\theta}}{\cos{\theta}}}[/tex]

Now, we apply the least common multiple on the denominator. So

[tex]\frac{\sin{\theta}}{\sin{\theta}+\cos{\theta}} = \frac{\frac{\sin{\theta}}{\cos{\theta}}}{\frac{\cos{\theta}+\sin{\theta}}{\cos{\theta}}}[/tex]

SImplifying the cosine:

[tex]\frac{\sin{\theta}}{\sin{\theta}+\cos{\theta}} = \frac{\sin{\theta}}{\sin{\theta}+\cos{\theta}}[/tex]

Which means that the identity is proved.

Answer:

4.5km

Step-by-step explanation:

2cm=1km

9cm=xkm

so to get from 2 to 9 all you do is multiply by 4.5 so do this the km and you will get 4.5km :)

Answer:

There are 473 millimeters in 1 pint.

Step-by-step explanation:

946 ml in 1 quart.

2 pints in 1 quart

hence,

946 ml in 2 pints

hence in 1 pint we have 946/2 ml

i.e. 473 ml in 1 pint.

:)

Answer:

473 milliliters

Step-by-step explanation:

If there are 946 mL in a quart and there are 2 pints in a quart, divide 946 by 2 to find how many mL are in one pint.

Here's an equation you can set up to solve the problem.

— 946 = 2x

— 946 / 2 = 2x / 2

— 473 = x

So, if we let x stand for the amount of mL in a pint, then 473 = x means there are 473 mL in a pint.

Answer:

the slope of the line passing through (4, 4)  and (9, 1)   is:

Slope = -3/5

Step-by-step explanation:

Given the points on the graph

Here:

(x₁, y₁) = (4, 4)

(x₂, y₂) = (9, 1)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [1 - 4] / [9 - 4]

               = -3 / 5

Thus, the slope of the line passing through (4, 4)  and (9, 1)   is:

Slope = -3/5

False

Step-by-step explanation:

The number on top of the division house is called the numerator.

The quotient is the result of the numerator / denominator.

Answer:

the answer is D.

Step-by-step explanation:

Since the square: (3√15) is common in both of them, you only focus on 21 and 9. if you subtract 9 from 21, it will give you 12. so, just add (3√15) to 12, which will give you: 12^3sqrt15

Answer:

Step-by-step explanation:

Assume that the [tex]20[/tex] mile-per-gallon car consumed all that [tex]75[/tex] gallons of fuel. How far would the cars have travelled?

[tex]20 \times 75 = 1500\; \text{miles}[/tex].

This assumption overestimated the total mileage of the two cars by [tex]1500 - 1325 = 175\; \text{miles}[/tex]. Here's why: for every gallon that the second ([tex]15[/tex] mile-per-gallon) car consumed, this assumption would overestimate the total mileage by [tex]20 - 15 = 5\; \text{miles}[/tex]. Therefore, the overestimation of [tex]175\; \text{miles}[/tex] corresponds to:

[tex]\begin{aligned} & 175\; \text{miles overestimated} \\ & \times \left(\frac{1\; \text{gallon consumed by the second car}}{5\; \text{miles overestimated}}\right)\\ &= \frac{175}{5}\; \text{gallons consumed by the second car} \\ &= 35\; \text{gallons consumed by the second car}\end{aligned}[/tex].

Therefore, the second car consumed [tex]35\; \text{gallons}[/tex]. The first car would have consumed [tex]75 - 35 = 40\; \text{gallons}[/tex].

Verify the results: [tex]40 \times 20 + 35\times 15 = 1325\; \text{miles}[/tex].

Answer:

[tex]\frac{7}{31} = 0.2258 = 22.58\%[/tex] probability that a randomly selected student prefers hip hop music.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, we have that:

14 students prefer hip hop music

There are 18 + 8 + 20 + 14 = 62 students

So

[tex]p = \frac{14}{62} = \frac{7}{31}[/tex]

[tex]\frac{7}{31} = 0.2258 = 22.58\%[/tex] probability that a randomly selected student prefers hip hop music.
