Answer:
Step-by-step explanation:
Let x be the number of students,
Y be profits, Rate per student is $550, initial investment is 25000
From the expression , denotes the constant value.
The initial investment is our constant value.
, Initial investment is the expenses hence
Therefore, our equation will be:-
I got y=x but I’m not sure if that’s correct
Answer: B 68
Step-by-step explanation:
x is a raw score to be standardized;
μ is the mean of the population;
σ is the standard deviation of the population.
Therefore the mean is zero. Seventy is -1z, or -1 standard deviation.
Step 2: 34.13% of the cases fall between -1 standard deviation and the mean. Thus there is a 34.13% chance that the score will fall between 70 and 75. This, of course, assumes a normal curve.
Step 3: An 80 is +1z or +1 standard deviation assuming a normal curve.
Step 4: Thirty four percent of the cases fall between +1 standard deviation and the mean. Thus there is a 34.13% chance that the score will fall between 75 and 80. This, of course, assumes a normal curve.
Step 5: Score between +1z and -1z, or +1 and -1 standard deviation account for 68.26% of the cases.
According to the Alternate Exterior Theorem, alternate exterior angles are congruent. So:
3x = 4x - 24
x = 24
But, this question is not over. This question is asking for angle RST, not x.
3(24) = 72
Hope this helped!
