Answer:

B. \text{cos}(52^{\circ}).

Step-by-step explanation:

We have been given a right triangle. We are asked to complete our given statement.

\text{sin}(38^{\circ}) equals ___.

We will use identity \text{sin}(x)=\text{cos}(90-x) to solve our given problem.

\text{sin}(38^{\circ})=\text{cos}(90^{\circ}-38^{\circ})

\text{sin}(38^{\circ})=\text{cos}(52^{\circ})

Therefore, \text{sin}(38^{\circ}) equals \text{cos}(52^{\circ}).

How do I compare decimal numbers
Neporo4naja [7]
When comparing decimals, start in the tenths place. The decimal with the biggest value there is greater. If they are the same, move to the hundredths place and compare these values. If the values are still the same keep moving to the right until you find one that is greater or until you find that they are equal.

Criterion: Identify IV, DV, and hypotheses and evaluate the null hypothesis for an independent samples t test. Data: Use the inf
Papessa [141]

The table is missing in the question. The table is provided here :

Group 1        Group 2

 34.86            64.14      mean

 21.99            20.46      standard deviation

  7                    7                n

Solution :

a). The IV or independent variable = Group 1

    The DV or the dependent variable = Group 2

b).

  $H_0: \mu_1 = \mu_2$

  $H_a:\mu_1 < \mu_2$

  Therefore,   $t = \frac{\bar x_1 - \bar x_2}{\sqrt{\frac{s_1^2}{n_1}+\frac{S_2^2}{n_2}}}$

$t = \frac{34.86 - 64.14}{\sqrt{\frac{21.99^2}{7}+\frac{20.46^2}{7}}}$

t = -2.579143

Now,   $df = min(n_1 - 1, n_2 - 1)$

           df = 7 - 1

               = 6

Therefore the value of p :

  $=T.DIST(-2.579143,6,TRUE)$

 = 0.020908803

The p value is 0.0209

$p< 0.05$

So we reject the null hypothesis and conclude that $\mu_1 < \mu_2$
