Answer:
![\frac{19}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B4%7D)
Step-by-step explanation:
Multiply the whole number by the denominator.
![4*4 = 16](https://tex.z-dn.net/?f=4%2A4%20%3D%2016)
Add the numerator (3) to 16.
![16 + 3 = 19](https://tex.z-dn.net/?f=16%20%2B%203%20%3D%2019)
19 will be our new numerator for the improper fraction. The original denominator (4) stays the same.
![4\frac{3}{4} = \frac{19}{4}](https://tex.z-dn.net/?f=4%5Cfrac%7B3%7D%7B4%7D%20%3D%20%5Cfrac%7B19%7D%7B4%7D)
Answer:
1/2n - 11 = -25
Hope this helps you! Have a good night!
Also, n = -28
1/2n - 11 = -25
1/2n - 11 + 11 = -25 + 11
1/2n = -14
1/2n / 1/2 = -14 / 1/2
n = -28
Check:
1/2(-28) - 11 = -25
-14 - 11 = -25
-25 = -25
Answer: 6
Explanation: The EXACT calculation would be 5.9215.. so the closest approximation would be
6, as it's only about .08 -ish away from 6.
Answer:
(2.1)
Step-by-step explanation:
assuming your period (.) is actually a comma in the U.S. it would be the coordinate (2,1) where x =2 and y =1.
The probability of randomly selecting an order that has at least 760
calories is 0.16
Step-by-step explanation:
The number of calories in an order of poutine at a certain fast food
restaurant is approximately normally distributed
1. The mean "μ" is 740 calories
2. The standard deviation "σ" is 20 calories
3. We need to find the probability of randomly selecting an order that
has at least 760 calories (x ≥ 760)
At first let us calculate z-score
∵ z = (x - μ)/σ
∵ x = 760 calories
∵ μ = 740 calories
∵ σ = 20 calories
∴ z = ![\frac{760-740}{20}=1](https://tex.z-dn.net/?f=%5Cfrac%7B760-740%7D%7B20%7D%3D1)
Use the normal distribution table of z (area to the left of z-score) to
find the corresponding area to z-score of 1
∵ The area corresponding of z = 1 is 0.84134
∵ We interested in x ≥ 760, we need the area to the right of z-score
∴ P(x ≥ 760) = 1 - 0.84134
∴ P(x ≥ 760) = 0.15866 ≅ 0.16
The probability of randomly selecting an order that has at least 760
calories is 0.16
