a = adult ticket price

s = student ticket price

7a + 2s = 87

---

4a + 6s = 74

4a = 74 - 6s

a = 74/4 - (6/4)s

a = 37/2 - (3/2)s

---

7a + 2s = 87

7(37/2 - (3/2)s) + 2s = 87

7(37/2) - 7(3/2)s + 2s = 87

(259/2) - (21/2)s + 2s = 87

(21/2)s - 2s = (259/2) - 87

(21/2)s - (4/2)s = 259/2 - 174/2

(17/2)s = 85/2

---

s = 85/2(2/17)

s = 85/17

Answer:

s = $5

a = $11

different animals have different fields of view. humans can generally see a 180° arc in front of them. horses can see 215° arc.

IgorLugansk [536]

Answer:

The area of the riders field of view is 987.5 square yards.

Step-by-step explanation:

The human has a 180° arc view. If the rider can see only 25 yards, the area of the riders field of view is a semi-circle (180° arc) of 25 yards of radius.

The semi-circle of 25 yards of radius has an area of:

$S=\dfrac{1}{2}\pi r^2=\dfrac{1}{2}\cdot3.16\cdot (25)^2=\dfrac{1}{2}\cdot3.16\cdot625=987.5$

The area of the riders field of view is 987.5 square yards.

Barbara claims that her horse can do simple addition problems. She showed her horse 8 different cards with simple addition probl

Nataliya [291]

Answer:

"Yes, the chances of getting 8 correct when guessing are very low"

Step-by-step explanation:

The point diagrams show us how likely is the occurrence of an event. When casting 8 coins there is a chance to get between 1 and 8 tails.

The dot plot tells us how many times 1, 2, 3, 4, 5, 6, 7 or 8 tails were obtained. When the number of trials increases, then the value with the most points in the diagram represents the number of queues most likely to be obtained, and the value with fewer points represents the least probable number of queues that can be obtained by casting 8 times a coin .

The dot plot for the experiment shows that it is very unlikely to get 8 queues when casting 8 coins. Of 53 times, this only happened once.

Just as it is unlikely to get 8 tails when throwing 8 coins, it is also unlikely that a horse guesses the 8 correct answers of the 8 simple sum problems. Then, the horse of barbara maybe did not guess the 8 answers.

Therefore the correct answer is option A:

"Yes, the chances of getting 8 correct when guessing are very low"
