Seeing your method 1 answer, it seems like you forgot that 42 dollars is for 6 guests, not just 1. The unit rate is the rate per guest, and if we divide 42 by 6, we get 7dollars/1person as our unit rate. Since 7 dollars is our unit rate, we can multiply that by 72 to get 504 dollars, therefore making 500$ per night more cost effective.
Another way to do this is to do 42*72, as you did, but then dividing the final product by 6 due to that 42*72 is for 72*6=432 guests (we get the 6 since the unit rate is 7$ per person and 42/7=6). Doing that, we get 3024/6=504, which is still greater than 500
Answer:
The proportion of scores reported as 1600 is 0.0032
Step-by-step explanation:
Let X be the score for 1 random person in SAT combining maths and reading. X has distribution approximately N(μ = 1011,σ = 216).
In order to make computations, we standarize X to obtain a random variable W with distribution approximately N(0,1)
The values of the cummulative distribution function of the standard Normal random variable, lets denote it 
are tabulated, you can find those values in the attached file. Now, we are ready to compute the probability of X being bigger than 1600
Hence, the proportion of scores reported as 1600 is 0.0032.
Answer:
$7.90 per pound
Step-by-step explanation:
11.85/3 = half pound = $3.95
3.95x2 = 7.9 = 1 pound
The y intercept is what the y value is when x is 0.
Set X to 0 and solve:
-2/9(0) + 1/3
0 + 1/3 = 1/3
The y-intercept is 1/3
Answer:
4/3
Step-by-step explanation:
y^2-y^1/x^2-x^1
plug in your numbers
8-4/4-1
simplify
4/3 is your slope
