The table displays the distribution of blood types A, B, AB, and O to the presence of the Rh factor that is either present (Pos.

) or absent (Neg.). A 6-column table has 3 rows. The first column has entries negative, positive, total. The second column is labeled A with entries .07, .33, .40. The third column is labeled B with entries .02, .09, .11. The fourth column is labeled AB with entries .01, .03, .04. The fifth column is labeled O with entries .08, .37, .45. The sixth column is labeled Total with entries .18, .82, 1.0. Use the information in the two-way table to complete the statement. The probability that a person has a positive Rh factor given that he/she has type O blood is percent. There is a greater probability for a person to have a than a person to have a positive Rh factor given type O blood

The lines in the graph of part A don't intersect at two whole numbers on the coordinate grid. Estimate the values of the solutio
mariarad [96]

Answer:

The solution lies at approximately (4.25,6.5).

Step-by-step explanation:

The estimate is pretty close for both equations. For the first equation, the estimate results in a value that is only 0.2125 units away from the constant. For the second equation, the estimate results in a value that is only 0.25 units away from the constant.

The number of days that homes stay on the market before they sell in Houston is bell-shaped with a mean equal to 56 days. Furthe
antoniya [11.8K]

Answer:

D. 8

Step-by-step explanation:

We have been given that the number of days that homes stay on the market before they sell in Houston is bell-shaped with a mean equal to 56 days. Further, 95 percent of all homes are on the market between 40 and 72 days.

As per empirical rule 95% of the data on bell curve lies between 2 standard deviations of mean.

So we can set an equation as:

72-56=2\sigma or

40-56=-2\sigma

16=2\sigma

\frac{16}{2}=\frac{2\sigma}{2}

8=\sigma

40-56=-2\sigma

-16=-2\sigma

\frac{-16}{-2}=\frac{-2\sigma}{-2}

8=\sigma

Therefore, the standard deviation for our given data is 8 and option D is the correct choice.

Does anyone know what f(x)=-5x-1 when f(-7) i need help with this please.
vodomira [7]

Answer:

f(-7) = 34

Step-by-step explanation:

If f(x) = -5x - 1, then . . .

f(x) = -5x - 1

f(-7) = -5(-7) - 1

       = 35 - 1

       = 34

. . . because in f(-7), the (-7) is the x-value you're supposed to use to find the value of the function.
