Which equation can be used to calculate the surface area of the triangular prism net show below?
slava [35]

The equation  that can be used to calculate the surface area of the triangular prism net shown below is mathematically given as

SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)  

<h3>Which equation can be used to calculate the surface area of the triangular prism net shown?</h3>

Generally, The region or area that is occupied by the surface of any particular item is referred to as that object's surface area.

In conclusion, the equation surface area of the triangular prism will be one that accommodates all parameters

SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)  

SA = (1/2)(5)(12) + (1/2)(5)(12) + (5)(2) + (12)(2) + (13)(2)

1. The mayor of a town has proposed a plan for the construction of an adjoining bridge. A political study took a sample of 800 v
Free_Kalibri [48]

Answer:

See step by step explanation

Step-by-step explanation:

Sample size   n  =  800

p₁  =  71 %      p₁ = 0,71     and  q₁ = 0,29

Claim from political strategy wants evaluation to see if that sample implies that residents who favor the construction are more than 68 %

Then  

p₀   =  68%      p₀ = 0,68

Sample size  800 big enough to use the approximation of binomial distribution to normal distribution

1) Hypothesis Test

Null Hypothesis                                  H₀          p₁  =  p₀

Alternative Hypothesis                      Hₐ          p₁  >  p₀

2)Test Statistics  z (s)

z(s)   =  (  p₁  -  p₀ ) / √p₁*q₁/n

z(s)   =  0,03 / √0,71*0,29/800

z(s)   =  0,03 /  0,016

z(s)  =  1,875

3) In the problem statement the expression " more than " has to be formulated in the alternative hypothesis and indicates that the test is one tail test to the right

4)  z(s)  =  1.875  from  z-Table we get  p-value  = 0,030

Now significance level is α  = 0,02

Therefore  p-value > 0.02

Then that value corresponds to the acceptance region for H₀.

We don´t have enough evidence to support the strategist´s claim

5) The level of significance is α = 0,02

6) If now we change  α to be equal to 0,01   α = 0,01

p-value > 0,01 and still we have to accept H₀

7) We accept H₀  we are not able to support strategist´s claim
