Required polynomial = x(x + 2)^3 = x(x^3 + 6x^2 + 12x + 8) = x^4 + 6x^3 + 12x^2 + 8x
Answer:
x = 21
Step-by-step explanation:
Sum of interior angles in a triangle = 180
x - 4 + 3x + 100 = 180
4x + 96 = 180
4x = 84
x = 21
Answer:
0.0125
Step-by-step explanation:
The P-value can be calculated by using excel function T.DIST.RT(2.968,6).
Right tail is used in the function because our alternative hypothesis has greater than sign (>) whereas 2.968 represent test statistic value and 6 represents degree of freedom. The resultant p-value from excel function is 0.0125.
Or if we use t- distribution right tail area table, we see that 6 for degree of freedom the value in table is there are two value 2.44691 and 3.14627 which corresponds to p=0.025 and p=0.01. As 2.44691 is smaller than 2.968 so we take p=0.01 against 3.14627. Thus, in this scenario p-value would be 0.01.
1 and 4
1² = 1 and 2² = 4 and 1 < 3 < 4
Answer:
B
Step-by-step explanation:
Hi,
2πr is the formula for circumference, you know your diameter is 4cm and radius is half of the diameter, so your radius is 2cm.
To find the circumference, you have to multiply 2 by 2 and pie. 2 x 2 is 4. So 4 times pie. B is your correct answer.
I hope this helps :)
