Answer:
A
Step-by-step explanation:
x=
−b±√b2−4ac
2a
x=
−(2)±√(2)2−4(2)(15)
2(2)
x=
−2±√−116
4
and there is really no solution
The answer is B. You will get that after multiplying 12.99 by 4, and then calculate the tax and add 2.50
Answer:
C. c = -4
Step-by-step explanation:
you must get c by itself. you have to divide both sides by 10. this gets rid of the 10c and keeps both sides equal
-40/10 = c
c = -4
Answer:
The data provide sufficient evidence that older people are more likely to be victimized.
Step-by-step explanation:
H 0 : P = 0.10
H 1 : P > 0.10 (Right tailed test)
n = 527, P = 0.1235
The test statistics
x = P - p / ![\sqrt{p*(1-p) / n}](https://tex.z-dn.net/?f=%5Csqrt%7Bp%2A%281-p%29%20%2F%20n%7D)
x = 0.1235 - 0.10 / ![\sqrt{0.10 * 0.90 / 527}](https://tex.z-dn.net/?f=%5Csqrt%7B0.10%20%2A%200.90%20%2F%20527%7D)
x = 0.0235 / ![\sqrt{0.09 / 527}](https://tex.z-dn.net/?f=%5Csqrt%7B0.09%20%2F%20527%7D)
x = 0.0235 / ![\sqrt{0.00017077798}](https://tex.z-dn.net/?f=%5Csqrt%7B0.00017077798%7D)
x = 0.0235 / 0.0130682049264618
x = 1.798257689731729
x = 1.798
P value = [1 - p(Z > 1.7980] (Right tailed test)
P value = 0.036089
The P - Value is very small, so <u>reject H0</u>
Conclusion: The data provide sufficient evidence that older people are more likely to be victimized.
Answer:
672
Step-by-step explanation:
Formula is length times width times height
14 x 8 = 112
112 x 6 = 672
