<span>the correct equation is
- 4j² + 3j - 28 =0
ax² + bx + c,
a = -4, b=3 c =- 28.
The discriminent D = b² - 4.a.cD = 3² - 4(-4)(-28)D = -439
If D ≥ 0 there are either 2 roots or one double if = 0)if D< 0, there are no real roots (but 2 imaginary roots)Since D < 0, then there is no real roots
The answer there is no real roots</span>
Answer:
B
Step-by-step explanation:
- A 95% confidence level interval will have 0.52 (lower interval) & 0.68 (upper interval) which means that that if 90 individuals root for North HS then p value is 0.6 which will fall in the 95% confidence interval range.
- For the option B the p value will also be same as in case A hence B is true as an alternative hypothesis.
- We can calculate P value
Confidence Interval = p ± z
Answer:
x=--2 and x=1/2
Step-by-step explanation:
this is the answer in simple form
Answer:
idk
Step-by-step explanation:
Answer:
2x+2y=x+5
(move the x next to the 2y)
= 2x+2y-x=5
(the x is negative because i moved it)
(collect the like terms)
= x+2y=5
(so the answer is...)
x+2y=5
