Answer:
(A) 30x+90=300
(B) $7
Step-by-step explanation:
Let x be the roller skating rink's entrance fee for one student.
So, the entrance fee for 30 students=30x
As each student pays a $3 fee to rent skates
So, the fee for rent paid by 30 students= $3x30=$90
The total cost for the students to enter the rink and rent skates= 30x+90
As given that total fee to enter the rink and rent skates is $300.
Therefore, 30x+90=300
(A) The required equation is 30x+90=300.
(B) On solving the equation, we have
Hence, the roller skating rink's entrance fee is $7.
By the empirical rule, 95% of the distribution is within 2 standard deviations. Since the other 5% is split equally between the two tails of the distribution, the empirical rule says 2.5% will be below -2 standard deviations from the mean.
... 266 days - 2×(16 days) = 234 days
The shortest 2.5% of pregnancies last less than 234 days.
So, hmmm keeping in mind that, an absolute value expression is in effect a piece-wise function, let's find its "slopes", the negarive slope on the left-side and the positive slope on the right side, and let's use the vertex point as our first point
what is the slope of a line that passes through (2, -1) and (0,7)
now, what is the slope of a line that passes through (2, -1) and (4,7)
since an absolute value expression is just a piece-wise with a +/- versions, then we can just combine those two.
You just need to subtract out the three checks that didn't clear on her last statement.
