The answer is 14 centimeters.

The midsegment of a trapezoid has length equal to the average of the two base lengths. Since the base lengths of this trapezoid are 11 and 17 centimeters, our midsegment has length (11+17)/2 = 14 centimeters.

Solution :

Given that , the base lengths of a trapezoid are 11 cm and 17 cm.

The base of a trapezoid means the two parallel sides of the trapezoid.

A trapezoid midsegment connects the mid point of the congruent sides of the trapezoid and is parallel to the base .

The length of the midsegment is the sum of the length of two bases divided by two.

length of trapezoid midsegment = $\frac{Sum\:of\:bases}{2}=\frac{17+11}{2}=14$

Hence, The length of midsegment of trapezoid is 14.

The odds of winning a rifle are 1:9 the probability of winning a carnival game is 0.15 does the raffle or the carnival game give

Lilit [14]

Answer:

Hence the carnival game gives you better chance of winning.

Step-by-step explanation:

Let the event of win be given by 1/10 in the game of rifle then the event of loose is given by 9/10

the

Odds in favor of a game are given by = P(Event)/ 1- P(Event)

Odds in favor of winning a rifle are given by = 1/10/ 1- 1/10

=1/10/9/10

=1/9

= 0.111

The probability of winning aa rifle game is 0.111

The probability of winning the carnival game is 0.15

Comparing the two probabilities 0.111:0.15

The probability of winning carnival game is greater than winning a rifle game

0.15>0.11

Hence the carnival game gives you better chance of winning.

The right answer is Option A: $x=\frac{rs-t}{2}$

Step-by-step explanation:

Given expression is;

$s=\frac{2x+t}{r}$

We will solve this expression for x, therefore,

Multiplying both sides by r

$r*s=\frac{2x+t}{r}*r\\rs=2x+t$

Subtracting t from both sides

$rs-t=2x+t-t\\rs-t=2x\\2x=rs-t$

Dividing both sides by 2

$\frac{2x}{2}=\frac{rs-t}{2}\\x=\frac{rs-t}{2}$

The right answer is Option A: $x=\frac{rs-t}{2}$
