Answer: No there isn't
Step-by-step explanation: What I did was I seen what 15/3 was and it = 5 so what you're supposed to do is, divide the top and bottom by each other to see if they're both all going to =5 or see what= the bottom number. If they don't all= the same number when you divide them, then there's no relationship
For example: 15/3=5 5/20=4, 7/25= 0.28, and 9/30= 0.3
They're all = to something different
D = 4n - 2
+2 +2
d + 2 = 4n
Divide both sides by 4
n = d + 2 / 4
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 =
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

Answer:
Please check explanations for answers
Step-by-step explanation:
a) The variable replacing y is g
The units are gallons
b) The variable replacing x is t
The units are minutes
c) We compare this with the general form of a straight line equation
g = 4t + 8
compared with y = mx + b
so we can see that b is 8 here
Putting the units , the intercept is 8 gallons
This means that at zero minute, or initially , the amount of gas in the truck’s tank is 8 gallons
In other words, the amount of gas in the tank of the truck before it started refueling in the gas station is 8 gallons
d) The slope is 4 gallons/minute
What the slope represents is the filling rate
It is simply the amount of gallons entering the gas tank per minute as the gas tank is refueling
Answer:
11 hours
Step-by-step explanation:
Let's set up a proportion so we can cross-multiply. We know that her rate is constant, so
Keeping units in helps to make sure that you have your fractions right-side-up. Now cross-multiply:
8x = 44*2
8x = 88
<u>x = 11 hours</u>
