  • 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

Point P partitions the directed segment from A to B into a 1:3 ratio. Q partitions the directed segment from B to A into a 1:3 r
olga2289 [7]

Answer:

c)No, P is the distance from A to B, and Q is the distance from B to A.

Step-by-step explanation:

Point P partitions the directed segment from A to B into a 1:3 ratio.

Ratio is 1:3

So AP is 1  and PB is 3

Q partitions the directed segment from B to A into a 1:3 ratio.

Ratio is 1:3

So BQ is 1  and QA is 3.

That is AQ= 3  and BQ= 1

The ratio of Q and P varies

AP =1  and AQ=3

So P  and Q  are not at the same point.

Because P is the distance from A  to B  and Q is the distance from B to A

Jarvis works in a garage £6 an hour. If he works on Saturday, he is paid time and a quarter. If he works on Sunday, he is paid t
ruslelena [56]

Answer: He is paid $90 last weekend.

Step-by-step explanation:

Since we have given that

Amount he earns per hour = $6

If he works on Saturday, he is paid time and a quarter .

Amount would be

6\times 1.25=\$7.5

If he works on Sunday, he is paid time and a half.

Amount would be

6\times 1.5=\$9

Number of hours he worked on Saturday = 6 hours

Number of hours he worked on Sunday = 5 hours

So, Total amount he is paid last weekend altogether is given by

6\times 7.5+5\times 9\\\\=\$90

Hence, he is paid $90 last weekend.
