Answer:
![-4x^{4} + x^{2} + 6](https://tex.z-dn.net/?f=-4x%5E%7B4%7D%20%2B%20x%5E%7B2%7D%20%2B%206)
Step-by-step explanation:
![(-4x^{4} + 6x^{2} + 3) - (5x^{2} - 3) = -4x^{4} + 6x^{2} + 3 - 5x^{2} + 3 = -4x^{4} + 6x^{2} - 5x^{2} + 3 + 3 = -4x^{4} + x^{2} + 6](https://tex.z-dn.net/?f=%28-4x%5E%7B4%7D%20%2B%206x%5E%7B2%7D%20%2B%203%29%20-%20%285x%5E%7B2%7D%20-%203%29%20%3D%20-4x%5E%7B4%7D%20%2B%206x%5E%7B2%7D%20%2B%203%20-%205x%5E%7B2%7D%20%2B%203%20%3D%20-4x%5E%7B4%7D%20%2B%206x%5E%7B2%7D%20-%205x%5E%7B2%7D%20%2B%203%20%2B%203%20%3D%20%20-4x%5E%7B4%7D%20%2B%20x%5E%7B2%7D%20%2B%206)
Answer:
a^x/y=1 x: 0
Step-by-step explanation: w.k.t, a^0=1( any variable raised to 0 is 1)
so, here the exponent is x/y which should have been 0 so that answer was 1.
Answer:
Step-by-step explanation:
- x² = 4² + (√34)²
- x² = 16 + 34
- x² = 50
- x = √50
- x = 5√2
9 x 8= 72, so the answer would be:
72
Answer:
CV for statistics exam = 15%
CV for calculus exam = 19%
Since the CV for calculus exam is higher, it has a greater spread relative to the mean than the statistics exam.
Step-by-step explanation:
To find coefficient variation we use the formula:
CV = (SD/mean) * 100
CV for the statistics exam:
where; SD= 5
mean= 75
CV = ( 5/75) *100
= 0.15 or 15%
CV for calculus exam
SD = 11
Mean= 58
CV= (11 /58) * 100
= 0.19 or 19%
