we know that

in the right triangle JKL

$sin(38\°)=cos(52\°)$

Because

$(38\°)$ and $(52\°)$ are complementary angles

$38\°+52\°=90\°$

therefore

<u>the answer is</u>

$cos(52\°)$

Answer:

3/10

Step-by-step explanation:

There are 10 students

5 of them voted either Los Angeles or New York

That means ignore (screw) the other 5 people

If 2/10 students chose Los Angeles,

that is 2/5 because the others didn't choose those cities that are part of the equation (nobody asked about the other people)

So if 5 people chose two groups of cities, and two people chose one city, that meant 3 chose the other

3/10 (remember its out of all of them) Students Voted for New York

Hope this helps :)

There is difference in the scores of males and females

Step-by-step explanation:

Given that a professor teaches a certain section of material using a lot of examples with sports and cars to illustrate. He is concerned that this may have biased his instruction to favor male students

Since simple variances are unequal, we can do t test for comparison of two means with unequal variances

$H_0 : \bar x =\bar y\\H_a : \bar x \neq \bar y$

Group Group One Group Two

Mean 84.00 78.00

SD 4.00 8.00

SEM 1.26 2.53

N 10 10

The mean of Group One minus Group Two equals 6.00

95% confidence interval of this difference: From 0.06 to 11.94

t = 2.1213

df = 18

standard error of difference = 2.828

The two-tailed P value equals 0.0480

Since p <0.05 we reject null hypothesis

There is difference in the scores of males and females
