Answer:

4/10 (2/5)

Step-by-step explanation:

Add all the bows together and then add ur number to the fraction.

EX: 1 blue bow, 6 purple bows, 6, pink bows what is the possibility to get a blue bow?

Add them all together, and then the denominator would be 13. So, there is one bow which means 1 in a 13 chance you will get the blue bow.

The ratio of boys to girls at King Middle School is 3:2. What is the ratio of girls to all

NeX [460]

The answer is: " 2 :5 " ; or, write as: " 2/5 " .

________________________________________________________

The ratio of 'girls' to 'all students' is: "2: 5 " ; or, write as: " 2/5 ".

________________________________________________________

Explanation:

________________________________________________________

Given: The ratio of boys to girls is: " 3:2 " .

Problem: Find the ratio of "girls" to "all students:

________________________________________________________

Note: This ratio of "boys to girls", which is " 3 : 2 " ;

________________________________________________________

→ can be expressed as " 3x: 2x" ;

in which the total number of students is: " 3x + 2x " = 5x " .

→ The total number of students is represented as: " 5x " .

________________________________________________________

→ The ratio of "girls to boys" is: "2x : 3x" .

→ {that is; the "inverse" of the ratio of "boys to girls"} ;

→ {that is; the "inverse" of " 3x: 2x" } ; → which is: " 2x : 3x " .

________________________________________________________

The ratio of "girls" to "all students" is: "2x : 5x " ; or " 2x/5x " ;

→ Both "x" values cancel ; {since: " x/x = 1 "} ;

_________________________________________________________

→ and we have the answer: " 2 :5 " ; or, write as: " 2/5 " .

_________________________________________________________

The ratio of 'girls' to 'all students' is: " 2 :5 " ; or, write as: " 2/5 ".

Jada should have multiplied both sides of the equation by 108.

Step-by-step explanation:

-4/9=x/108

you must multiply both sides

108*-4/9 = x*108

Recent homebuyers from a local developer allege that 30% of the houses this developer constructs have some major defect that wil

umka21 [38]

Answer:

3.54% probability of observing at most two defective homes out of a random sample of 20

Step-by-step explanation:

For each house that this developer constructs, there are only two possible outcomes. Either there are some major defect that will require substantial repairs, or there is not. The probability of a house having some major defect that will require substantial repairs is independent of other houses. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

30% of the houses this developer constructs have some major defect that will require substantial repairs.

This means that $p = 0.3$

If the allegation is correct, what is the probability of observing at most two defective homes out of a random sample of 20

This is $P(X \leq 2)$ when n = 20. So

$P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)$

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{20,0}.(0.3)^{0}.(0.7)^{20} = 0.0008$

$P(X = 1) = C_{20,1}.(0.3)^{1}.(0.7)^{19} = 0.0068$

$P(X = 2) = C_{20,2}.(0.3)^{2}.(0.7)^{18} = 0.0278$

$P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0008 + 0.0068 + 0.0278 = 0.0354$

3.54% probability of observing at most two defective homes out of a random sample of 20
