in 1900 in the United States there were 40 death from diphtheria for every 100,000 people. How many diphtheria deaths would be expected in 1900 in a town of 40,000?

Answers

Answer: Diphtheria once was a major cause of illness and death among children. The United States recorded 206,000 cases of diphtheria in 1921, resulting in 15,520 deaths. Diphtheria death rates range from about 20% for those under age five and over age 40, to 5-10% for those aged 5-40 years. Death rates were likely higher before the 20th century. Diphtheria was the third leading cause of death in children in England and Wales in the 1930s.

Since the introduction of effective immunization, starting in the 1920s, diphtheria rates have dropped dramatically in the United States and other countries that vaccinate widely. Between 2004 and 2008, no cases of diphtheria were recorded in the United States. However, the disease continues to play a role globally. "In 2007, (4,190 cases) of diphtheria were reported, which is likely an underestimate of the actual number of cases."

Determine the equation of the perpendicular bisector JK whose endpoints are J(-4,9) and K(6,1). Show all your work below. (Use of the grid is optional.)​

Answers

Answer:

[tex]y=\frac{5}{4}x+\frac{15}{4}[/tex]

Step-by-step explanation:

Coordinates of segment with endpoints J and K are,

J(-4, 9) and K(6, 1)

Midpoint of the segment JK = [tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

                                               = [tex](\frac{-4+6}{2},\frac{9+1}{2})[/tex]

                                               = (1, 5)

Slope of JK, [tex](m_1)=\frac{y_2-y_1}{x_2-x_1}[/tex]

                             = [tex]\frac{9-1}{-4-6}[/tex]

                             = [tex]-\frac{4}{5}[/tex]

Let the equation of perpendicular bisector passing through [tex](x_1,y_1)[/tex] and slope [tex]m_2[/tex] is,

[tex]y-y_1=m_2(x - x_1)[/tex]

By the property of perpendicular lines,

[tex]m_1\times m_2=-1[/tex]

[tex]-\frac{4}{5}\times m_2=-1[/tex]

[tex]m_2=\frac{5}{4}[/tex]

Therefore, equation of the line passing through midpoint (1, 5) and slope = [tex]\frac{5}{4}[/tex] will be,

[tex]y-5=\frac{5}{4}(x-1)[/tex]

[tex]y=\frac{5}{4}x-\frac{5}{4}+5[/tex]

[tex]y=\frac{5}{4}x+\frac{15}{4}[/tex]

A distribution of values is normal with a mean of 114.5 and a standard deviation of 23.
Find P47, which is the score separating the bottom 47% from the top 53%.
P47 =
Enter your answer as a number accurate to 1 decimal place. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.

Answers

Answer:

The score separating the bottom 47% from the top 53% is 112.8

Step-by-step explanation:

Let X denote the random variable whose values are normal with a mean of 114.5 and a standard deviation of 23.

Compute the 47th percentile as follows:

[tex]P(X<x)=0.47\\\\P(\frac{X-\mu}{\sigma}<\frac{x-114.5}{23})=0.47\\\\P(Z<z)=0.47[/tex]

The corresponding z-value is,

z = -0.075

*Use the z-table.

Compute the value of x as follows:

[tex]\frac{x-114.5}{23}=-0.075\\\\x=114.5-(0.075\times 23)\\\\x=112.775\\\\x\approx 112.8[/tex]

Thus, the score separating the bottom 47% from the top 53% is 112.8

Answer:

  ∠B = 53°

  ∠C = 127°

  ∠D = 127°

Step-by-step explanation:

The trapezoid is isosceles, as indicated by the hash marks on sides AD and BC. This means it is symmetrical about the vertical center-line. Angles on the right will have the same measures as the symmetrical angles on the left.

So, you know immediately that ∠B = ∠A = 53°.

Because AB ║ DC, ∠A and ∠D are supplementary. That is, ...

  ∠D = ∠C = 180° -53°

  ∠D = ∠C = 127°

Answers

Answer:

I believe the answer would be 240

Step-by-step explanation:

If you divide 60 by 3 you will get 20 which is how much one sweatshirt will cost. Then you multiply 12 by 20 than you should get 240 which might be the answer. I hope that this is helpful and that you get it right.

Answer:

Step-by-step explanation:

3 shirts cost $60

Take 3x4=12

Take $60x4= 240

There you have your answer.

You can also:

60÷3= 20

Each shirt cost $20
