Answer:

10. $23.75^{o}$

8. $34.76^{o}$

Step-by-step explanation:

10. each step is 36, so i added it twice to get 72.

then add 16 twice = 32

this gives us two sides to our triangle.

We can now use tan since we know opp and adj

tan 32/72 = .44

arctan = 23.75

8. since we again know the opposite and adjacent sides to the angle e are trying to find we can use tan again.

tan 12.5/18 = .694

arctan= 34.76

Political parties rely heavily upon polling to measure their support in the electorate. In a country with four major political p

liberstina [14]

Answer:

a) The claim is not plausible

b) claim is plausible and the type of bias here is response bias

Step-by-step explanation:

Given data:

Number of political parties = 4

coffee party got the support of 435 out of 1183 randomly selected voters in a poll conducted.

A) Construct and interpret a 98% confidence interval to estimate the proportion of voters who support the coffee party

H0 ( null hypothesis ) : p = 0.42

Ha ( alternate hypothesis ) : p ≠ 0.42

z value for 98% confidence interval = 2.326

using 98% confidence interval the value of p = ( 0.3668, 0.3686 )

hence the claim is not plausible

B) Determine the type of bias

Assume the actual number of people = 1200

and 17 people did not respond

hence number of people who responded = 1200 - 17 = 1183

Therefore the claim by the manager is plausible because 17 people did not respond and the type of bias here is response bias

attached below is a detailed solution of the problem of the A part

Solve log_x(1/32)=-5

leva [86]

Remember

$log_a(b)=c$ translates to $a^c=b$

so
$log_x(\frac{1}{32})=-5$ translates to $x^{-5}=\frac{1}{32}$
remember, if a^b=c^b when b=b, then a=c
and x^-m=1/(x^m)

hmm
$x^{-5}=\frac{1}{32}$
$\frac{1}{x^5}=\frac{1}{32}$
32=x⁵
5th root both sides
2=x
x=2

What do I do on this model?

Fiesta28 [93]

Answer:

In the model, you can see that it is split up into four parts. It also shows that the whole model is 2/3. So, an equation you could write is $\frac{2}{3} / 4\\$
