Answer:

0.1667 = 16.67% probability that she/he has diabetes

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Living below the poverty level.

Event B: Having diabetes.

30% of the elderly people are living below poverty level.

This means that [tex]P(A) = 0.3[/tex]

5% of the elderly population falls into both of these categories.

This means that [tex]P(A \cap B) = 0.05[/tex]

If a randomly selected elderly person is living below the poverty level, what is the probability that she/he has diabetes

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.05}{0.3} = 0.1667[/tex]

0.1667 = 16.67% probability that she/he has diabetes

The ratio of the size of the dollhouse item to the doll house is 14 : 9.

Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).

First convert feet to inches

1 feet = 12 inches

12 x 6 = 72 inches

dollhouse item : doll house

112 : 72

The function g(x) is a discrete function. It is continuous between -7 to -2, -2 to 3, and 3 to 8. And the open circle at -7, -2, 3, and 8. And the jump of the g(x) is 4 units after every interval.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

Answer:

The p-value of the observed statistic is 0.15866

Step-by-step explanation:

The given parameters of the system are;

The standard deviation of the foam height, σ = 20 mm

The null hypothesis, H₀; μ = 175 mm

The alternative hypothesis, Hₐ; μ > 175 mm

The number of observations that make the sample, n = 4

The observed statistic, [tex]\overline x[/tex] = 185

The test statistic is given as follows;

[tex]Z=\dfrac{\bar{x}-\mu }{\dfrac{\sigma}{\sqrt{n}}}[/tex]

Therefore, we get;

[tex]Z=\dfrac{185-175 }{\dfrac{20}{\sqrt{4}}} = 1[/tex]

P(Z > 1) = 1 - P(Z < 1) = 1 - 0.84134 = 0.15866

The p-value of the observed statistic = 0.15866

Answer:

2 pounds are left.

Step-by-step explanation:

12 pounds divided into 6 parts (or sixths) = 2 pounds each. 5 of those 6ths were used, so 10 pounds used. 2 pounds are left.

Alternately, multiply 12 x 5 for your numerator = 60, divide by 5, your denominator, and get 10 pounds used.

Answer:

the answer is x=5

The division is given below.

The quotient is 125 and the remainder is 0.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

1875 ÷ 15

This can be written as,

 15 ) 1875 ( 125

        15    

          37    

          30

            75

            75

              0

Thus,

The quotient is 125 and the remainder is 0.
