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

3) Substitute 7 for x to get the answer.

Answers

Answer:

Samantha will earn $1,150 on the 7th day.

Step-by-step explanation:

Linear Modeling

It consists of finding the equation of a line that represents the data provided in a specific situation.

Tina's (or Samantha's) earnings are $550, x, $750,... where x is an unknown amount for the second day of her new restaurant.

The earnings continue to increase at the same rate until the 7th day. We must find the earnings for that last day.

The linear model can be found in several ways. We'll use the slope-point form of the line, finding first the slope and then the y-intercept.

The equation of the line in slope-intercept form is:

y=mx+b

Being m the slope and b the y-intercept.

1) Find the slope

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (1,550) and (3,750), thus:

[tex]\displaystyle m=\frac{750-550}{3-1}=100[/tex]

2) Get the equation of the line

Substituting into the equation of the line, we get:

y=100x+b

Select the point (1,550), substitute into the above equation, and solve for b:

550=100(1)+b

Solving:

b=450

Thus we complete the equation of the linear model:

y=100x+450

3) Substitute 7 for x

y=100(7)+450

y=1,150

Samantha will earn $1,150 on the 7th day.

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."

A fair coin is continually flipped until heads appears for the 10th time. Let X denote the number of tails that occur. Compute the probability mass function and the expected value of X.

Answers

Answer:

P (X = i) = (i + 9 _ 9) (1/2)^(i + 10)

Step-by-step explanation:

Range of X = {0, 1, 2, 3......10}

P (X = i) = P (NB (10, ½) i = 10)

P (X = i) = (i + 9 _ 9) (1/2)^10 (1/2)^(1+10-10)

P (X = i) = (i + 9 _ 9) (1/2)^10 (1/2)^1

P (X = i) = (i + 9 _ 9) (1/2)^(i + 10)

Patuxet once stood on the exact site where the Pilgrims built Plymouth. In 1605, fifteen years before the Pilgrims came, Squanto went to England with a friendly English explorer named John Weymouth. He had many adventures and learned to speak English. Squanto came back to New England with Captain Weymouth. Later Squanto was captured by a British slaver who raided the village and sold Squanto to the Spanish in the Caribbean Islands. A Spanish Franciscan priest befriended Squanto and helped him to get to Spain and later on a ship to England. Squanto then found Captain Weymouth, who paid his way back to his homeland. In England Squanto met Samoset of the Wabanake (Wab-NAH-key) Tribe, who had also left his native home with an English explorer. They both returned together to Patuxet in 1620. When they arrived, the village was deserted13 and there were skeletons everywhere. Everyone in the village had died from an illness the English slavers had left behind. Squanto and Samoset went to stay with a neighboring village of Wampanoags.One year later, in the spring, Squanto and Samoset were hunting along the beach near Patuxet. They were startled to see people from England in their deserted village. For several days, they stayed nearby observing the newcomers. Finally they decided to approach them. Samoset walked into the village and said Welcome, Squanto soon joined him. The Pilgrims were very surprised to meet two Indians who spoke English.
