Verify this triangle is a right triangle: a = 12 b = 7 C = 15

Answer:

No

Step-by-step explanation:

Formula is a squared + b squared = c squared

12 times 12 = 144

7 times 7 = 49

144 + 49 = 193

so 15 times 15 should = 193

but 15 times 15 = 225

Answer:

This triangle is not a right triangle

Step-by-step explanation:

If it were a right triangle, then the pythagorean theorum would work

a^2 + b^2 = c^2

12^2 + 7^2 = 15^2

144 + 49 = 225

This is not true because 144+49=193, not 225

So this triangle is not a right triangle

Match the following items.
Novosadov [1.4K]

The Matchup are:

1. 1/3(24+15)=1/3•24+1/3•15 -  distributive property

2. 101+(29+417) = (101+29) + 417 -  associative property of addition.

3. (-14)+81 = 81 + (-14) - commutative property of addition.

4. -72 +0=-72 - additive identity.

5. 13/17•17/13=1 -multiplicative inverse.

<h3>What is a distributive property?</h3>

The distributive Property is one that connote the fact that if a factor is said to be multiplied by the sum or the addition of two terms, it is vital to multiply all of the two numbers by using the factor, and lastly carry out the addition operation.

Hence, The Matchup are:

1. 1/3(24+15)=1/3•24+1/3•15 -  distributive property

2. 101+(29+417) = (101+29) + 417 -  associative property of addition.

3. (-14)+81 = 81 + (-14) - commutative property of addition.

4. -72 +0=-72 - additive identity.

5. 13/17•17/13=1 -multiplicative inverse.

Determine if events A and B are mutually exclusive.
gladu [14]

Answer:

A) Not mutually exclusive

Step-by-step explanation:

Given

P(A) = \frac{1}{4}

P(B) = \frac{3}{5}

P(A\ or\ B) = \frac{7}{10}

Required

Determine if they are mutually exclusive or not

Mutually exclusive are defined by:

P(A\ or\ B) = P(A) + P(B)

So, we have:

P(A\ or\ B) = \frac{1}{4} + \frac{3}{5}

Take LCM

P(A\ or\ B) = \frac{5+12}{20}

P(A\ or\ B) = \frac{17}{20}

By comparing:

P(A\ or\ B) = \frac{17}{20} ---- Calculated

P(A\ or\ B) = \frac{7}{10} ---- Given

We can conclude that A and B are not mutually exclusive because:

\frac{17}{20} \ne \frac{7}{10}
