Answer:

(A) 24 and 66

Step-by-step explanation

Complementary angles add up to 90 degrees

Supplementary angles add up to 180 degrees

(A) 24 + 60 = 90

These 2 angles sum to 90, so therefore they are complementary

(B) 56 + 124 = 180

These 2 angles sum to 180, so they are supplementary, not complementary

(C) 34 + 66 = 100; 34 + 56 = 90

While 34 and 56 sum to 90 degrees, 34 and 66 sum to 100, so this answer does not satisfy the question

(D) 56 + 124 = 180; 66 + 114 = 180

Both of these angle pairs are supplementary, so they do not satisfy the answer to the question

What is the value of x rounded to nearest tenth
Ivahew [28]

Answer:

6.5 cm

Step-by-step explanation:

Here, <em>the tangent line squared is equal to the secant line times the secant line outside the circle</em>.

That is <em>20.2² = 14.7 * (14.7 + 2x)</em> --> it is 2x because the secant goes through <em>the whole circle</em>.

Simplify: <em>408.04 = 216.09 + 29.4x</em>

Subtract: <em>191.95 = 29.4x</em>

Divide: <em>x = 6.528911565</em> ≈ 6.5 cm

Rationalize the denominator of square root of negative 49 over open parentheses 7 minus 2 i close parentheses minus open parenth
navik [9.2K]

The answer is the option d, which is: d) \frac{-77+21i}{130}

The explanation for this problem is shown below:

1. Smplify the denominator and rewrite the numerator in this form:

\frac{7i}{7-2i-4-9i} \\\frac{7i}{3-11i}

2. Multiply the denominator and the numerator by the conjugated (3+11i) and simplify the expression, as following:

\frac{7i(3+11i)}{(3-11i)(3+11i)} \\ \frac{21i+77i^{2}}{121+9}  \\ \frac{-77+21i}{130}

3. As you can see, you obtain the expression shown in the option mentioned above.

Two studies were done on the same set of data, where study I was a one-sided test and study II was a two-sided test. The p-value
mixer [17]

Answer:

0.060

Step-by-step explanation:

In a two tailed test the probability of occurrence is the total area under the critical range of values on both the sides of the curve (negative side and positive side)

Thus, the probability values for a two tailed test as compared to a one tailed test is given by the under given relation -

p-value = P(Z< -\frac{\alpha }{2} )+P(Z >\frac{\alpha}{2})\

Here P\frac{\alpha}{2} = 0.030

Substituting the given value in above equation, we get -

probability values for a two tailed test

=0.030 + 0.030\\= 0.060
