Answer:

Answer:

33.14\°

Step-by-step explanation:

Let

Y ----> field of vision that Yash's camera would need

we know that

Applying the law of sines

\frac{sin(Y)}{25}=\frac{sin(41\°)}{30}

Solve for sin(Y)

sin(Y)=\frac{sin(41\°)}{30}(25)

Y=sin^{-1}[\frac{sin(41\°)}{30}(25)]

Y=33.14\°

How far away from home was she ?
Vlad [161]
Approx. 5 miles I would say give or take the 1/2 mile shortcut by taking a straight path back to the house. I don't know if you need an exact distance but I hope this helps.

In ΔNOP, OP = 7, PN = 13, and NO = 19. Which statement about the angles of ΔNOP must be true?
zmey [24]

The angles must be acute and all the measured angles must be different.

<h3>What is a triangle?</h3>

This a shape with 3 sides and angke

If in ΔNOP, OP = 7, PN = 13, and NO = 19, then the measure of the angles must be different as well;

Hence the statement that must be true about the angles is that the angles must be acute and all the measured angles must be different. The given triangle must also be a scalene triangle

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
