The answer is a

Step-by-step explanation:

Using point (0,0) and (3,-9)

Slope of the line = -9-0/3-0 = -9/3 = -3

Equation of the line using point (0,0)

Need help ASAP!!!!!
svetlana [45]

Answer:

cos 45 degree = A/H

cos 45 degree =  2 square root 2 / x

x = 2 square root 2 / cos 45 degree

x = 4

Sin 45 degree = O/H

Sin 45 degree = y/ 4

4 x Sin 45 degree = y

y = 2.83

or

we could use tan

tan 45 degree = O/A

tan 45 degree = y / 2 square root 2

2 square root 2 x tan 45 degree = y

y = 2.83

i hope this would elp a little bit.

Doss [256]
Female:                                     Male:
60                                              35
96                                             109
26                                              31
n₁=no. of entries=3                    n₂=no. of entries=3
s₁=sample standard                   s₂=sample standard 
      deviation=35.005                       deviation=43.924
x₁=sample mean=60.666           x₂=sample mean=58.333

Here s and x are calculated from calculator.
Now,
for significance level
1-α=90%
1-α=0.9
α=0.1
α/2=0.05

As population variances are unknown for both Male and female so the best suitable formula is

    (x₁ - x₂) ± tα/2,v₁ * \sqrt{ \frac{s_1^2 }{n_1} + \frac{s_2^2}{n_2} }
   ........1

where v(degree of fredom)=(s₁²/n₁+s₂²/n₂)² / ((s₁²/n₁)²/n₁-1)+(s₂²/n₂)²/n₂-1))
    by putting values 
           v=3.81026
From Statistics table,
      See the t table at α/2=0.05  and v=3.81026
use interpolation as v value is not in the table,
      3.81026-3/4-3 = x-3.182/2.776-3.182
                          x= 2.853
by putting values in eq. 1 we get
  
(60.666-58.333) ± (2.853)*\sqrt{ \frac{35.005^2 }{3} + \frac{43.924^2}{3} }      

  2.333 ± 92.516 is the correct answer.
