So sorry if it’s wrong, but I believe it is..
Answer:
Explanation:
The distance traveled by June, from A to D, is the sum of the distance from A to C plus the distance from C to D:
- Travel from A to D = Distance AC + Distance DC.
<u>1) Find the distance AC</u>
- Triangle ABC is a right triangle, from which you have to calculate the hypotenuse (AC), knowing angle A (50º), and its adjacent leg (217 m).
- AC = 217m / cos (50º) = 337.59m
<u>2) Find the distance DC</u>
First, you need to calculate the side BC which is a common side of both triangles ABC and DBC.
You can use Pythagora's or a trigonometric function (tangent or sine).
- tan (50º) = BC / 217 m ⇒ BC = 217 m × tan (50º) = 258.61 m
Now you can use Pythagora's theorem to find the distance DC, which is the hypotenuse of the triangle DBC:
- DC² = (170m)² + (258.62)² = 95,779.41m²
<u>3) Find the total distance traveled from A to D</u>
- Travel from A to D = Distance AC + Distance DC = 337.59m + 309.48m = 647.07 m ≈ 647m.
Answer:
IQR is 4, median is 58.
Step-by-step explanation:
Enter these values in a list, hit stat > calc > 1-var stats. That gives you the 5 number summary. To get IQR, subtract Q3 from Q1.
If 11 like basketball and 16 like hockey, you get a total of 27, but if 2 said both then you don't want to double count them, so a total of 25 students answered. If 25 total students answered but 2 liked both, then 23 only liked one.
The answer to (a) is 5 students did not like either sport
The answer to (b) is 23 students liked exactly one sport.
Answer:
how many 2/3's are "in 1" means how many times 2/3 can be divided into 1. Anything divided into 1 is the inverse of what's divided into 1. So there are 1/ (2/3)s. That's = 3/2. 3/2 is one and a half. If you add 2/3 and half of 2/3, you get 3/3, which is 1. So it's right.
