Well, its a given more or less when referred to the measure of an Arc, it's usually meant the CENTRAL ANGLE made by that arc in this case, 148 is the CENTRAL ANGLE, so if BCD is 148 and BC is 105, then CD is the rest of the 148. 148 for the central angle, if we use up 105 for BC, how much is left over for CD?
Answer:
w+12 = l
so
(w +(w + 12) )2= p
Step-by-step explanation:
Answer: (x−3)(x+7)
=(x+−3)(x+7)
=(x)(x)+(x)(7)+(−3)(x)+(−3)(7)
=x^2+7x−3x−21
=x^2+4x−21
Answer: the value us 2.064
Step-by-step explanation:
To determine the t value, we would need the t distribution table. Since degree of freedom is known as 24, we would determine alpha/2
A 95% confidence level is 95/100 = 0.95
1 - alpha = 0.95
alpha = 1 - 0.95
alpha = 0.05
alpha/2 = 0.05/2 = 0.025
this is the area to the left. The area to the right 1 - 0.025 = 0.975
alpha/2 = 0.975
Looking at the t distribution table, the t value is
2.064
