If two angles are complimentary then their sum would equal to 90 degree.
i.e., x + 3x + 30 = 90
4x = 90 - 30
x = 60 / 4
x = 15

In short, Your Answer would be Option A

Hope this helps!

Answer:

The value of x is 15 .

Option (A) is correct.

Step-by-step explanation:

As given

∠1 and ∠2 are complementary.

i.e the sum of ∠1 and ∠2 is 90° .

Thus

∠1 + ∠2 = 90°

x° + (3x+30)° = 90°

x + 3x + 30 = 90

4x = 90-30

4x = 60

x = \frac{60}{4}

x = 15

Therefore the value of x is 15 .

Option (A) is correct.

Which value of a in the exponential function below would cause the function to shrink? f(x) = a(three-halves) Superscript x Four
Natalka [10]

Answer:

Four-fifths

Step-by-step explanation:

As we know that

By multiplying the function by a constant, we may expand or shrink the function in the y-direction.

Now we have

y=a(b^{x})

if a> 1  > the function would enlarge

if 0< a < 1 > the function would shrinks

Now

For case A

a = \frac{4}{5}

0 < (\frac{4}{5} )< 1 ....... > the function would shrinks

For case B

a = \frac{5}{4}

(\frac{5}{4} )>1 .......> the function would enlarge

For case C

a = \frac{3}{2}

(\frac{3}{2} )>1 .........> the function would enlarge

For case D

a = \frac{7}{4}

(\frac{7}{4} )>1 .........> the function would enlarge

Therefore the second option is correct

What method of assigning probabilities to a simple event uses relative frequencies?
Alex Ar [27]

The empirical method is the right answer.

Empirical probability is calculated by dividing the number of times an event was seen in your data by the entire sample size. An event's relative frequency is strongly connected to an empirical probability, also known as an experimental probability.

Empirical probability bases its estimation of the likelihood that a specific result will recur on the number of instances of that outcome within a sample set. In short, the empirical method uses relative frequencies to determine probabilities.

Here's another question with an answer similar to this about empirical method:
