Mathematics

Answer:

9

Step-by-step explanation:

If the sine of an angle is equal to the cosine of an angle, that means that the sides adjacent and opposite to that angle are equal. One triangle that has two equal sides is an isosceles triangle. We can set this triangle to be a 45-45-90 degree triangle, which means that the angle would be 45.

Now, we have to find the value of

4\tan^2(45)

and

5\tan(45)

The tangent of 45 is 1, so 1 squared times 4 is 4.

We have 4\tan^2(45) = 4.

Again, the tangent of 45 is 1, and 1 times 5 is 5.

We have 5\tan(45) = 5

5 + 4 = 9

Which hypotheses are being tested by the chi-square test? The distribution of gender is different for the three different goals.
Karo-lina-s [1.5K]

Answer:

The null hypothesis is that the most important goal and gender are independent, and the alternative is that they are dependent.

Step-by-step explanation:

Chi Square test is used to test relationship between categorical (nominal) variables of a population. Eg : Testing men & women  for any attribute, lets say empathy

  • Null Hypothesis states that there is no relationship between  the attribute & categorical variable, they are independent.
  • Alternate Hypothesis states that there is relationship between the attribute & categorical variable, they are dependent.

Eg : Null hypothesis states that there is no difference of empathy level in men & women. Alternate Hypothesis states that there is difference of empathy level in men & women.
