Answer: 169 times
Step-by-step explanation:
Circumference : 64inches
Distance: 300 yards
We know that 1 yard is 36 inches.
300yd*36 = 10800inches
10800/64 = 168.75 but rounding up makes it 169 times.
Answer:
20
Step-by-step explanation:
It is 20 because 0.75 is on the map and its actualy distance is 15 so 15/0.75 is 20
Con un sistema de ecuaciones, tiene-se que:
- Cada pera cuesta $1.
- Cada manzana cuesta $3.
--------------
- Usando la información dada en el texto, se construye un<em> sistema de ecuaciones</em> para encontrar el precio de cada pera e de cada manzana.
- Yo diré que el precio de cada manzana es x y de cada pera es de y.
--------------
- <u>La compra de 6 manzanas y 8 peras cuesta $26</u>, lo que significa que una de las ecuaciones es:
- <u>Cada manzana cuesta lo triple de cada pera</u>, lo que significa que la outra ecuacione es:
--------------
Aplicando esta relacion en la primera ecuación, se encontra el precio de cada pera.
Cada pera cuesta $1.
--------------
Para cada manzana:
Cada manzana cuesta $3.

The expected values of the binomial distribution are given as follows:
1. 214.
2. 21.
3. 31.
<h3>What is the binomial probability distribution?</h3>
It is the <u>probability of exactly x successes on n repeated trials, with p probability</u> of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
For item 1, the parameters are:
p = 3/7, n = 500.
Hence the expected value is:
E(X) = np = 500 x 3/7 = 1500/7 = 214.
For item 2, the parameters are:
p = 0.083, n = 250.
Hence the expected value is:
E(X) = np = 250 x 0.083 = 21.
For item 3, the parameters are:
p = 1/13, n = 400.
Hence the expected value is:
E(X) = np = 400 x 1/13 = 31.
