Answer:

a) 11/20

b) 0.55

Step-by-step explanation:

1. A fraction represents a part of a whole. The fraction of the animals that are cows is 44/80 because out of 80 animals, there are 44 that are cows. 44 is a part of that whole.

  • Now, to simplify 44/80, let's find the common factors between them:
  • 44: 1, 2, 4, 11, 22, 44
  • 80: 1, 2, 4, 8, 10, 20, 40 80
  • Since the GCF is 4, we divide the numerator and denominator by it
  • \frac{44/4}{80/4} = \frac{11}{20}
  • Therefore, the fraction of the animals that are cows in simplified form is 11/20.

2. To find 11/20 as a decimal, we just have to divide 11 by 20 because the numerator represent the dividend, and the 20 represents the divisor.

  • 11 ÷ 20
  • 0.55
  • Therefore, as a decimal, the fraction 11/20 is 0.55.

Answer:

11/20 and 0.55

Step-by-step explanation:

44 of the 80 animals are cows. A fraction to represent this is 44/80. To simplify this, you can divide the numerator and denominator by 4 to get 11/20. if you want to put it as a decimal multiply both the numerator and denominator by 5 to get 55/100 or 0.55

Andrei [34K]

Answer:

The probability that the town has 30 or fewer residents with the illness = 0.00052.

Step-by-step explanation:

So, we have the following set of data or information or parameters given from the question above and they are; the number of people living in that particular society/community/town = 74,000 residents and the proportion of people that the diseases affected = .000215.

The first step to do is to determine the expected number of people with disease. Thus, the expected number of people with disease = 74,000 × .000215 = 15.91.

Hence, the probability that the town has 30 or fewer residents with the illness = 1.23 × 10^-7 × 15.91^30/ 2.65253 × 10^-32 = 0.00052.

Note the formula used in the calculating the probability that the town has 30 or fewer residents with the illness =  e^-λ × λ^x/ x!

Answer:

Option A.

Step-by-step explanation:

According to this survey results :

Students : 80 like viking and 20 like patriot.

Teachers : 5 like viking and 15 like patriot.

In Option B it is given that patriot is more popular in students while viking is more popular in teachers which is not correct.

In option c patriot is equally popular in students and teachers, which is also not correct. because patriot is popular in 20% of students but 80% in teachers, which is not correct.

In option d there is no difference between students and teachers, this statement is also not correct because there is lots of differences in their choices.

In Option A it is said that viking is more popular in students but patriot is more popular in teachers. this is correct.

Make ‘w’ the subject.
Romashka-Z-Leto [24]

Answer:

w = (cv +dy) / (cb - ad)

Step-by-step explanation:

Multiply through by c

aw + y = c(bw + v) / d                Multiply by d

d(aw + y) = c(bw + v)                  Remove the brackets

daw + dy = cbw + cv                  Subtract dy from both sides.

daw +dy - dy = cbw + cv -dy

daw = cbw + cv - dy                   Subtract cbw from both sides

daw - cbw = cbw - cbw + cv - dy

daw - cbw = cv -  dy                  Isolate W on the left.

w(da - cb) =  cv - dy                   Divide by cb - ad on both sides.

w = (cv - dy) / (ad - bc)                Answer
