I think it's 8 b/c 24 minutes divided by 3 miles is 8 minutes per mile.
Answer:
17000 batteries
Step-by-step explanation:
Three years and one month is equivalent to the mean minus one standard deviation.
Three years and seven months is equivalent to the mean plus one standard deviation.
For a normal distribution, we know that 68% of population is between mean ± 1 sd, then can be expected that 25000*68% = 17000 of batteries last between three years and one month and three years and seven months
Answer:
b=41
Step-by-step explanation:
180=19v-41+(180-(20v+39))+17v
v=5
180=19v-41+b+17v
180=19(5)-41+b+17(5)
b=41

Hello
let's assume that we are looking for x >=0
![4x^2=100 \dfrac{4x^2}{4}=x^2=\dfrac{100}{4}=25\\\sqrt{x^2}=25\\ |x| = 5 x = 5 \ or \ x=-5](https://tex.z-dn.net/?f=4x%5E2%3D100%20%3C%3D%3E%20%5Cdfrac%7B4x%5E2%7D%7B4%7D%3Dx%5E2%3D%5Cdfrac%7B100%7D%7B4%7D%3D25%5C%5C%3C%3D%3E%5Csqrt%7Bx%5E2%7D%3D25%5C%5C%3C%3D%3E%20%7Cx%7C%20%3D%205%20%3C%3D%3E%20x%20%3D%205%20%5C%20or%20%5C%20x%3D-5)
Let's assume that we are looking for x>=0
so the correct answer is 5
Answer:
√160 or 12.65 or 4√10
