The equivalent expression to 7^13/7^7 would be 7^6.

<h3>What are equivalent expressions?</h3>

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.

We have given an expression as  7^13/7^7

The equivalent expression;

\dfrac{7^{13}}{7^7} \\\\7^{13-7}\\\\7^6

Hence, The equivalent expression to 7^13/7^7 would be 7^6.

Marat540 [252]

Answer:

a. 0.75

b. 0.5526

c.  0.1974

Step-by-step explanation:

Probability is typically expressed as a fraction where the numerator is the number of desired outcomes and the denominator is the total number of outcomes. In this case the suitable parts is the desired outcome and the total shipment is the total parts:

\frac{suitable}{total}=\frac{15}{20}=\frac{3}{4}=0.75

The probability the both the first and second part are suitable:

\frac{15}{20}*\frac{14}{19}=\frac{210}{380}=0.5526

Since the probability of getting a suitable part the first time is 15/20, then there is one less suitable part and one less part overall to choose on the second time, or 14/19.

Lastly, the probability of choosing a suitable part the first time is again 15/20, but the second part not being suitable would be 5/19:

Triangle PQR has vertices at the following coordinates: P(0, 1), Q(3, 2), and R(5, -4). Determine whether or not triangle PQR is
ruslelena [56]
PQ =  \sqrt{(3-0)^2+(2-1)^2}= \sqrt{9+1}= \sqrt{10}    \\ QR= \sqrt{(5-3)^2+(-4-2)^2}= \sqrt{4+36}= \sqrt{40} \\PR= \sqrt{(5-0)^2+(-4-1)^2}= \sqrt{25+25}= \sqrt{50}

PR is the longest side.
The triangle will be right if
PQ² + QR² = PR²

PQ² + QR² = (√10)² + (√40)² = 10 + 40 = 50
PR² = (√50)² = 50
50=50  so, ΔPQR is <span>a right triangle.</span>

Calculate the area of the irregular polygon shown below:
olga nikolaevna [1]
26 Square Inches. 
If you find the area of the two missing fragments, which are 3 in. by 4 in., you can make the equation 2(3 x 4)= 24. Find the area of the whole 5 in. by 10 in. which is equal to 50 in. Subtract 24 from 50 and you get 26.
