Answer:
The answer is $0.63 per pound of rice.
Step-by-step explanation:
5 ÷ 8 = 0.625
Convert 0.625 to hundredths place
0.625 = 0.63 = $0.63
The probability that x is between 420 and 460 is 0.25778
The sum of independent normally distributed random variables is normally distributed with mean equal to the sum of the individual means and variance equal to the sum of the individual variances.
so, the mean would be,
μ = 100 + 150 + 200
μ = 450
and standard deviation would be,
σ = 15+ 20 + 25
σ = 60
We need to find the probability that x is between 420 and 460.
P(420 < x < 460)
= P( 420 - μ < x - μ < 460 - μ)
= P((420 - μ)/σ < (x - μ)/σ < (460 - μ)/σ)
= P((420 - 450)/60 < Z < (460 - 450)/60)
= P (-1/2 < Z < 1/6)
= P(-0.5<x<0.167)
= 0.25778
Therefore, the probability is P(420 < x < 460) = 0.25778

Answer:
Just flip it 180 degrees
Step-by-step explanation:
Absolute value of the integers is the distance between zero and the number when represented on the number line. Absolute value is always positive, no matter the integer is negative or positive.
131 and -131 are two integers with place value 131.
Because if we see the distance between 0 and 131, the place value is 131 and similarly the distance between 0 and -131 is also 131.
