Answer:
The amount of nuts is 16 kg and cereal mixture is 44 kg to obtain 60 kg of a mix that will sell for $1.40 per kg
Step-by-step explanation:
Let
x=nuts at $2.50 per kg
y=cereal at $1 per kg
x+y=60 kg (1)
2.50x+y=1.40(60) (2)
From (1)
x=60-y
Substitute x=60-y into (2)
2.50x+y=1.40(60)
2.50(60-y)+y=84
150-2.5y+y=84
-1.5y=84-150
-1.5y=-66
Divide both sides by -1.5
y=44 kg
Substitute y=44 into (1)
x+y=60
x+44=60
x=60-44
=16
x=16 kg
Answer:
4
Step-by-step explanation:
By having a clear glance at the picture , there are 4 acute angles. They are AMP , PMQ , BMQ & BMR
- 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
