Answer: 8/145

Step-by-step explanation: Rewriting the table

Positive and Negative stand for the result of the test

Yes and No stand for having the disease

Positive | Negative | Total

<u>Yes </u><u> | 137 | 8 | 145</u>

<u>No </u><u> | 16 | 139 | 155</u>

<u>Total</u><u> | 153 | 147 | 300</u>

probability of getting someone who tests negative, given that he or she had the disease.

P(Negative | Yes) = <u>P(Negative ∩ Yes)</u> = <u> 8 </u>

P(Yes) 145

The combined age of three relatives is 120 years. James is three times the age of Dan, and Paul is two times the sum of the ages

d1i1m1o1n [39]

Answer:

Step-by-step explanation:

From the problem statement, we can create the following equation:

$J + P + D = 120$

where $J$ is the age of James, $P$ is the age of Paul, and $D$ is the age of Dan.

From the first part of the second sentence, we can set up the following equation:

$J = 3D$

From the last part of the second sentence, we can set up the following equation:

$P = 2(J + D)$

We can substitute the second equation into the last one to get the following:

$P = 2(3D + D)$

$P = 2(4D)$

$P = 8D$

We can then substitute the last two equations in the first to solve for $D$ :

$3D + 8D + D = 120$

$12D = 120$

$D = 10$

Plugging this into the other two equations will give us the remaining ages:

$P = 8D$

$P = 8(10)$

$P = 80$

$J = 3D$

$J = 3(10)$

$J = 30$

Out of a class of 150 students, two-fifths opted for German classes and one-third opted for Italian classes. The remaining opted

Yuliya22 [10]

Fraction of students that opted for French = $\frac{4}{15}$

The total number of students = 150

Fraction of students that opted for German = $\frac{2}{5}$

Fraction of students that opted for Italian = $\frac{1}{3}$

Fraction of students that opted for French = 1 - Fraction of students that opted for German - Fraction of students that opted for Italian

Fraction of students that opted for French = $1-\frac{2}{5} - \frac{1}{3}$

Fraction of students that opted for French = $\frac{15-6-5}{15}$

Fraction of students that opted for French = $\frac{4}{15}$

Quadratic factored form

bearhunter [10]

Quadratic functions can be written in three forms. The parameters and are the roots of the function (the x-intercepts of the graph ). Converting a quadratic function to factored form is called factoring. ... The parameter is the y-intercept, while the parameter is the slope of the tangent at 0.

Alguien me podria ayudar a resolverlos con su procedimiento

Scilla [17]

Answer:

Step-by-step explanation:

f(x) = 2x² + x - 3

f'(x) = 4x + 1

f'(x) = 4(-1) + 1 = -3 slope

f(x) = 2(-1)² + (-1) - 3 = -2

(-1, -2)

-2 = -3(-1) + B

B = -5 y intercept

y = -3x - 5

f(x) = 1/x² = x⁻²

f'(x) = -2x⁻³

f'(-2) = -2(-2)⁻³ = -2/-8 = 1/4 slope

y = 1/4x + B

1/4 = 1/4(-2) + B

B = 3/4

y = 1/4x + 3/4
