GaryK [48]

Answer:

v = 9

Step-by-step explanation:

Since the triangles are similar then corresponding angles are congruent

∠B and ∠Q are corresponding angles, hence

6v - 5 = 5v + 4 ( subtract 5v from both sides )

v - 5 = 4 ( add 5 to both sides )

v = 9

Annual starting salaries for college graduates with degrees in business administration are generally expected to be between $30,

saveliy_v [14]

Answer:

The value is $n =1351$

Step-by-step explanation:

From the question we are told that

The standard deviation is $\sigma = \$3750$

The margin of error is $E = \$ 200$

From the question we are told the confidence level is 95% , hence the level of significance is

$\alpha = (100 - 95 ) \%$

=> $\alpha = 0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the sample size is mathematically represented as

$n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2$

=> $n = [1.96 * 3750 }{200} ] ^2$

=> $n =1351$

From the pythagorean theorem the square lenght of hypotenuse is equal to sum of square lenght of base and side

(6.5)^2 = x^2 + (2.5)

42.25 = x^2 + 6.25 subtract 6.25 from both sides

36 = x^2 and x = 6
