You use the tan/cos/sin rules

So we know that the hypotenuse=46.8, opposite=44

We can use sin (negative) to find it

sin^-1=opp/hyp
sin^-1=44/66.8
=70 degrees

Hope this helps!! :)

Which ordered pair in the form (x,y) is a solution of this equation? 7x-5=1

leva [86]

ANSWER

B. (-2,-3)

EXPLANATION

The given equation is

$7x - 5y = 1$

We want determine which of the ordered pairs is a solution to the given equation.

For point A(-3,-2)

$7( - 3) - 5( - 2) = 1$

$- 21 + 7 = 1$

This statement is false.

For option B(-2,-3)

We have

$7( - 2) - 5( - 3) = 1$

$- 14 + 15 = 1$

For option C(0,4)

We have

$7(0) - 5(4)=1$

$0 - 20=1$

For option D(4,0)

We have

$7(4) - 5(0)=1$

$28 - 0=1$

This statement is false.

Nadya [2.5K]

Answer:

Test statistic =1.30

Step-by-step explanation:

Given that you are testing the claim that the proportion of men who own cats is significantly different than the proportion of women who own cats.

Men Women Difference

Sample size n 60 120

Proportion p_1, p_2 0.45 0.35 0.10

60 120 180

0.45 0.35 0.383333333

27 42 69

p = 0.3833

Std error for proportion difference = $\bar p (1-\bar p)(\frac{1}{n_1}+\frac{1}{n_2})\\=0.3833(0.6167)(\frac{1}{60}+\frac{1}{120})\\=0.0769$

Test statistic = $\frac{p_1-p_2}{\bar p (1-\bar p)(\frac{1}{n_1}+\frac{1}{n_2}) }$

= $1.3008$

=1.30
