Suppose that 1 month before the election a random sample of 500 registered voters are surveyed. From this sample 270 indicate th

Aleonysh [2.5K]

Answer:

[ 0.4964, 0.5836 ]

Step-by-step explanation:

Data provided in the question:

Total sample size = 500

person voting for smith = 270

thus,

P( person voting for smith ), p = $\frac{270}{500}$ = 0.54

Confidence level = 95%

now,

standard error, SE = $\sqrt{\frac{p(1-p)}{n}$

or

SE = $\sqrt{\frac{0.54(1-0.54)}{500}$

or

SE = 0.0223

now,

Confidence interval = p ± ( z × SE )

here,

z value for 95% confidence interval is 1.96

Confidence interval = [ 0.54 - ( 1.96 × 0.0223 ), 0.54 + ( 1.96 × 0.0223 ) ]

= [ 0.54 - 0.0436 , 0.54 + 0.0436 ]

= [ 0.4964, 0.5836 ]

Find the values of a through e that make these two relations inverses of each other. a = b = c = d = e = An image shows 2 tables

Sergio039 [100]

Answer:

a = -3.8

b = -2.6

c = 1.7

d = 4.4

e = 1.0

Step-by-step explanation:

In the figure attached, the tables are shown.

In an inverse relationship, any point (x,y) in one table is transformed to (y,x) in the other one. For example, in Table A coordinate (1, 2) is present, then in Table B (the inverse), coordinate (2, 1) must be present.

Help with 7 and 8 and explain

Tems11 [23]

Answer:

7. $44^{\circ}$

8.

Step-by-step explanation:

7. Using Cosine Rule

$a^2=c^2 +c^2+bcCos(a)$

=> $a^2=20^2+15^2-2*20*15Cos(68^o)$

$a^2=400.24$

$a=20.00$

=>Using Sine Rule

$20/Sin 68^o=15/sinB$

$ABC=44^o$
