X and y intercepts. So x intercept is where y=0 and y intercept is where x=0. Also positive or negative meaning where y>0 (positive) and where y<0 (negative). Use these hints to do it. If you can’t then just let me know...

Any 5 <br>algebraic formulas
Ostrovityanka [42]

Answer:

a2 – b2 = (a – b)(a + b)

(a + b)2 = a2 + 2ab + b2

a2 + b2 = (a + b)2 – 2ab

(a – b)2 = a2 – 2ab + b2

(a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca

(a – b – c)2 = a2 + b2 + c2 – 2ab + 2bc – 2ca

(a + b)3 = a3 + 3a2b + 3ab2 + b3 ; (a + b)3 = a3 + b3 + 3ab(a + b)

(a – b)3 = a3 – 3a2b + 3ab2 – b3 = a3 – b3 – 3ab(a – b)

a3 – b3 = (a – b)(a2 + ab + b2)

a3 + b3 = (a + b)(a2 – ab + b2)

(a + b)4 = a4 + 4a3b + 6a2b2 + 4ab3 + b4

(a – b)4 = a4 – 4a3b + 6a2b2 – 4ab3 + b4

a4 – b4 = (a – b)(a + b)(a2 + b2)

a5 – b5 = (a – b)(a4 + a3b + a2b2 + ab3 + b4

Conduct a full hypothesis test and determine if the given claim is supported or not supported at the 0.05 significance level. A
monitta

Solution:-

- The population proportion, P = 0.03 ( 3 % )

- The sample proportion, p = 0.058 ( 5.8 % )]

- The sample size , n = 85.

- State the hypothesis:

                   Null hypothesis : P = 0.03 ( 3 % )

                   Alternate hypothesis : P ≥ 0.03 ( 3 % )

- The rejection region is defined by the significance level α:

                         significance α = 0.05

                         Z-critical = Z_α = Z_0.05

                         p-value = Z_0.05 = 1.645

- The Z-statistics:

                   Z = \frac{\sqrt{n}*(p - P ) }{\sqrt{P*(1-P)} }\\\\Z = \frac{\sqrt{85}*(0.058 - 0.03 ) }{\sqrt{0.03*(1-0.03)} }\\\\Z = 1.5132

- Compare against the rejection value ( p - value ):

                   Z-critical = 1.645

                   Z-test = 1.5132

                   Z-test  < Z-critical  ... ( Null not rejected )

- We fail to reject the Null hypothesis, there is not enough evidence to support the manager's claim that the production process is out of control. Hence, we can support that the production process is not out of control.

5, 6, 7 will these numbers create a right triangle<br> true or false
kobusy [5.1K]
So in order to tell if something makes a right triangle we would use the formula Pythagorean theorem.a^2+b^2=c^2 and it must be equal and the same if not then those sides cant be use to make a right triangle

5^2+6^2=7^2

25+36=49

61=49

No ! False
