The answer should be 1526.8yd³
Answer:
a) Mean, median, mode = 56.5
b) 
Step-by-step explanation:
Normally distributed data have the same value for the mean, median and mode. This value is the addition of the maximum value by the minimum, divided by 2.
Also, the standard deviation in a normally distributed sample can be approximated by the following formula:
So
a) Estimate the values of Mean, Median, and Mode.
Highest value = 98
Minimum value = 15
b) Estimate the value of the standard deviation of these data
Max = 98
Min = 15
So
Answer:
B.
Step-by-step explanation:
The function above the x-axis looks like a parabola, so it must have an x^2 term. It also has an open circle, so it must have a > symbol.
The function below the x-axis has a closed circle, so it must have a <= symbol. It is also a 3rd degree polynomial.
Answer: B.
Answer:
x=8
Step-by-step explanation:
Angles 1 and 5 are corresponding angles.
If angles 1 and 5 are congruent, then the lines are parallel.
This means the measurement of angle 1 needs to equal the measurement of angle 5.
This is the equation we must solve:
3x+10=4x+2
Subtract 3x on both sides:
10=1x+2
Subtract 2 on both sides:
8=1x
Use multiplicative identity property:
8=x
So if x=8, then the angles 1 and 5 which are corresponding are congruent.
If corresponding angles are congruent, then the lines are parallel.
4x + 3y = 19 multiply this by 4
5x - 4y = 47 multiply this by 3:-
16x + 12y = 76..............(1)
15x - 12y = 141............(2)
Add (1) + (2);-
31x = 217
x = 7
Now plug = 7 into the first equation:-
4(7) + 3y = 19
3y = 19 - 28 = -9
t = -3
Solution is x = 7, y = -3.
