Tell whether each pair of angle measurements are complementary, supplementary or neither.  36°,24°  18°,72°  96°,84°
Serggg [28]

Given:

The pairs of angles are:

36°,24°

18°,72°

96°,84°

To find:

Whether each pair of angle measurements are complementary, supplementary or neither.

Solution:

Two angles are complementary if there sum is 90 degrees.

Two angles are supplementary if there sum is 180 degrees.

For 36° and 24°,

36^\circ+24^\circ =60^\circ

So, this pair is neither complementary not supplementary.

For 18° and 72°,

18^\circ+72^\circ =90^\circ

So, this pair is complementary.

For 96° and 84°,

96^\circ+84^\circ =180^\circ

So, this pair is supplementary.

horsena [70]

Answer: 8\sqrt{6}

Step-by-step explanation:

\frac{2^4\sqrt{3}}{\sqrt{2}}

2^{\frac{7}{2}}\sqrt{3}

2^{\frac{7}{2}}=2^{3+\frac{1}{2}}

2^3\cdot \:2^{\frac{1}{2}}=

2^3\sqrt{2}

= 2^3\sqrt{2}\sqrt{3}=

2^3\sqrt{2\cdot \:3}

=2^3\sqrt{6}

2^3=8

Answer- 8\sqrt{6}

15c² - 5c. Factorise completely ​
KATRIN_1 [288]

Looking at the problem, what we must do to complete this question is to completely factor the expression that was provided.  The expression that was provided is 15c^2 - 5c.

The first step that we must do is to take a look at the expression and see what the two pieces of the expression have in common.  We can see that both 15c^2 and -5c have the number 5 and the variable c associated with them so we can factor out those two.

<u>Factor out 5c</u>

  • 15c^2 - 5c
  • 5c(\frac{15c^2}{5c}) - 5c(\frac{5c}{5c})
  • 5c(3c) - 5c(1)
  • 5c(3c - 1)

Now we have completely factored out the expression that was provided in the problem statement and we came to final answer of 5c(3c - 1).

Answer:

Hello a value is missing in your question below is the value

samples of n = 10

answer : 24.63 <  μ  < 25.370

Step-by-step explanation:

Given :

Sample size = n = 10

Z∝/2 = Z0.0256 = 1.95

next calculate for margin of error

E = Z∝/2 * ( 0.6 /  / \sqrt{10} )

   = 0.370

therefore at  94.87% confidence interval the estimated population mean is

x - 0.370 < μ <  x + 0.370

25 - 0.370 < μ < 25 + 0.370

24.63 <  μ  < 25.370
