Class A
mean = (2 + 4+ 6 + 14 + 22)/5 = 48/5 = 9.6
median = 6

class B
mean = (10 + 12+ 14 + 16 + 22)/5 = 74/5 = 14.8
median = 14

answer is Class B

higher mean and median

If i u have 110 dogs and the ratio of puppies is 2:3. How many puppies

navik [9.2K]

Question: You have 110 dogs (which is the total amount of dogs/pups) and the ratio of the puppies is 2:3. How many puppies are there?

Add 2 and 3 which adds to 5 (You need to combine all the "pie pieces")

Now, divide 110 by 5

$110$ ÷ $5=22$

Now multiply 2 and 22

$2*22=44$

Now multiply 3 and 22

$3*22=66$

The ratio is 44:66

Answer: There are 44 puppies

John wants to measure the width of a stream using the methods he has learned in geometry. He puts a stake in the ground opposite

otez555 [7]

John's method to determine the width of the stream uses the knowledge

that the tangent of 60° is approximately 1.7.

The proper sequence John would use to find the width of the stream are;

Step 1; John drives a stake opposite the tree to establish a line between two points

Step 2; John uses a compass to walk away from the stakes at a right angle

Step 3; On the path John walks until he finds a line of sight to the tree that equals 60 degrees

Step 4; John drives a second stake in the ground

Step 5; John measures the the distance between the two stakes

Step 6; John multiplies the distance between the two stakes by 1.7 to find the distance.

Reasons:

The steps that can be used to measure the width of the stream are;

Step 1: Drive a stake opposite the tree on the other side of the stream.

Step 2: With the aid of a compass, walk at right angles to the line formed by the stake and the tree.

Step 3; Keep walking along the previous path till a point is reached where the angle formed between the line of site to the tree and the walk path is 60°.

Step 4; At the point where the line of sight to the tree is 60°, a second stake is driven in the ground.

Step 5; Measure the distance between the stakes that are placed in the ground.

Step 6; Given that by trigonometry, the ratio of the width of the stream to the distance between the two stakes is tan(60°) ≈ 1.7, multiply the distance between the two stakes by 1.7 to find the width of the stream.

$\displaystyle tan(60^{\circ}) = \mathbf{\frac{Width \ of \ stream}{Distance \ between \ stakes}}$

The possible question options are;

John measures the the distance between the two stakes

John uses a compass to walk away from the stakes at a right angle

John multiplies the distance between the two stakes by 1.7 to find the distance

John drives a second stake in the ground

On the path John walks until he finds a line of sight to the tree that equals 60 degrees

John drives a stake opposite the tree to establish a line between two points.
