a snapshot is taken at a busy intersection and analysed. it shows that 16 people are in personl vehicles, 56 people are in buses,and 24 are walking. what fraction ( in lowest terms) of the people are in vehicles?

Answers

Answer 1

Answer:

Answer:

3/4, or three quarters of people are on vehicles.

Step-by-step explanation:

solution 1:find the number of vehicles

personal vehicles and buses are both vehicles so we add the number, 16 and 56 to get a total of 72 people on vehicles. the total number of people there is 16+56+24 and this is 96. now we express this as a fraction and get 72/96. we simplify by dividing 24 from both top and bottom to get 3/4.

solution 2:find the number of people walking and subtract.

24 are walking out of the 96. this means 1/4 people are walking and the rest are on vehicles. 1- 1/4 is 3/4, so 3/4 people are on vehicles.

The area of a circle is 615.44 in2. What is the diameter of the circle? Use 3.14 for π.

Answers

The diameter of the circle is 28 inches.

Given:
Area of a circle = 615.44 in²

Area of a circle is computed by multiplying pi and the radius raised to the 2nd power.

A = π r²
615.44 in² = 3.14 * r²
615.44 in² / 3.14 = r²
196 = r²
√196 = √r²
14 in = r

Diameter is twice its radius. So, d = 2r; d = 2 * 14 ; d = 28 inches

Answer:

The diameter= 28in

What is the theoretical probability of a coin landing tails up?

Answers

Answer:

The probability that a fair coin lands tail up is 1/2, which is equal to 0.5.

Step-by-step explanation:

There are two possible outcomes when a coin is flipped (saving for the case when the coin lands on its side.)

The coin lands head-up;
The coin lands tail-up.

If the coin is fair, the two outcomes should be equally likely. In that case, apply the following formula:

$\begin{aligned}&\text{Probability that the coin lands tail-up}\n =&\frac{\text{Number of outcomes that the coin lands tail-up}}{\text{Total Number of equally-likely possible outcomes}}\n=&(1)/(2) \n=& 0.5 \end{aligned}$ .

Credit for the phrasing of this probability formula goes to the Khan Academy article "Probability: the basics".

Mikasi and Julie are determining which size sports drink is the better buy per ounce: a 16-ounce bottle for $1.95 or a 36 ounce bottle for $3.05. Who is correct? Explain.Mikas: 16-oz bottle: 12.2¢ per ounce
36-oz bottle: 8.5¢ per ounce

Julie: 16-oz bottle : 8.2¢ per ounce
36-oz bottle: 11.8¢ per ounce

Answers

The answer is
Mikas: 16-oz bottle: 12.2¢ per ounce
36-oz bottle: 8.5¢ per ounce

To calculate price per ounce, we will use the proportion:
16 ounces : $1.95 = 1 ounce : x
Crossing the products:
x = $1.95 × 1 ounce ÷ 16 ounces
x = $0.122 = 12.2¢
So, 16-oz bottle is 12.2¢ per ounce.

Similarly:
36 ounces : $3.05 = 1 ounce : x
Crossing the products:
x = $3.05 × 1 ounce ÷ 36 ounces
x = 0.085 = 8.5¢
So, 36-oz bottle is 8.5¢ per ounce.

It can be concluded that Mikas was correct.
