Hi there, I believe the answer is 20. Because, each corner is 4 chairs plus every two feet, equals 20. Hope this helps!

Variable: Temperature
saul85 [17]
  • The 20th percentile represent the temperature value which is less than or equal to the 20% of the temperature values in the distribution.
  • The 20th percentile temperature is 36.5°C which is Mr. Whitney's temperature.
  • The mean temperature value in °Fahrenheit is 98.249°F
  • The standard deviation value of temperature in °F is 32.734°F

The 20th percentile represents the score at which less than or equal to 20% of the scores in a distribution may be found. This is the score at which less than or equal to 20% of the temperature values in the distribution may be found.

Mr. Whitney's temperature :

20th percentile ;

20% of (n)

Where n = count of temperature values = 130

20% × 130 = 26th term

The 26th falls in 36.5 temperature value.

The mean temperature reading in degree Fahrenheit :

°F = (9/5)°C + 32

Mean in °C = 36.805

°F = (9/5) × 36.805 + 32

°F = 66.249 + 32

= 98.249°F

The standard deviation of temperature reading in degree Fahrenheit :

°F = (9/5)°C + 32

Standard deviation in °C = 0.408

°F = (9/5) × 0.408 + 32

°F = 0.7344 + 32

= 32.7344°F

In the continental United States,the ratio of states that border an ocean is 7:9 .How many of the states border an ocean?
Delvig [45]
So, there are 48 states, let's divide them into 16 groups  (because 7+9=16)


48/16=3

so that means there are 16 groups of 3 states.

and those groups are in a ratio of 7:9, seven to 9 groups.

I assume that the 7 refers to the states that border an ocean, then the number of states will be 7*3=21

Solve for z a(t+z)=45z+67
ladessa [460]
Solve for z a(t+z)=45z+67
1. Expand
at+az=45z+67

2. Subtract at from both sides
az=45z+67-at

3. Subtract 45z from both sides
az-45z=67-at

4. Factor out the common term z
z(a-45)=67-at

5. Divide both sides by a - 45
z= \frac{67-at}{ya-45}

Answer: 
z= \frac{67-at}{a-45}

A lightbulb manufacturer ships large consignments of lightbulbs to big industrial users. When the production process is function
Mashutka [201]

Answer:

a) P[ Pf | Ptd ]  = 0,428

b) P[ Pf | Nd ]  = 0,692

Step-by-step explanation:

We will call:

Pf  Probability of functioning correctly    60 %   or 0.6

Pfn  Probability of malfunctioning   40 %  or  0,4

PNd Probability of nondefective bulb

D₁  Probability of defective bulb when the process is correctly working

D₂  Probability of defective bulb when the process is in malfunction condition

Ptd Total probability of defective bulbs

Then applying theorem´s Bayes  have

P [ A | B ]  =  P(A) * P [ B | A ] / P(B)

a) Probabilty of the process is functioning correctly given that we pick up a defective bulb

The total probability of defective bulbs is equal to, probabilty of defective bulbs when the process is Ok, plus probability of defective bulbs when the process  is in malfunctioning condition, therefore

Ptd  = (0,6)*(0,25) + (0,40)*(0,50) = 0,15 * 0,20 = 0,35

P[ Pf | Ptd ]  =  Pf * P [ Pd | Pf ] / Ptd    =  0,6 * 0,25 / 0,35

P[ Pf | Ptd ]  = 0,428

b)  P [ Pf | Nd ]

P[ Pf | Nd ]  =  Pf *  P [Nd | Pf ] / PNd

PNd  = 1 - Ptd    =  1 - 0,35   =  0,65

P[ Pf | Nd ]  = 0,6 * 0,75 / 0,65   =  0,692

P[ Pf | Nd ]  = 0,692
