Why do you think we need to convert normal distribution to standard normal distribution?

Answers

Answer 1

Answer:

The standard score (more commonly referred to as a z-score) is a very useful statistic because it (a) allows us to calculate the probability of a score occurring within our normal distribution and (b) enables us to compare two scores that are from different normal distributions

The angles of a triangle are (x - 5), (x + 15)°
and (2x + 10). Given that the sum of the
angles of a triangle is 180°, calculate the size
of each angle.

Answers

Answer:

35°, 55°, 90°

Step-by-step explanation:

Since all the angles of a triangle equal 180, add them all together and set them equal to 180.

(x-5)+(x+15)+(2x+10)=180

Now solve for each angle.

(40-5)

=35°

(40+15)

=55°

(2(40)+10)

=90°

Now check your work.

35°+55°+90°

=180°

A survey found that 68% of students do their homework before 10:00 P.M. Predict how many students out of 1,095 do their homework before 10:00 P.M.

Answers

Answer:

744.6 or if you round it 745

Step-by-step explanation:

Step 1: Divide 1095 by 100

In this case, the number that we are "comparing" to 100 is 1095, so we must first normalize the number by dividing it by 100. The operation we have to solve is this:

1095/100= 1095÷100= 10.95

Step 2: Multiply 10.95 by 68 to get the solution

Now that we have our normalized number, 10.95, we just have to multiply it by 68 to get our final answer. The forumla for this is obviously quite simple:

10.95×68= 744.6

One angle of an isosceles triangle measures 70°. Which other angles could be in that isosceles triangle?

Answers

Answer:

Step-by-step explanation:

The total of all 3 angles in every triangle equals 180 degrees. An isosceles triangle has two side lengths equal and two angle degrees equal.

So you either have two angles with each having 70 degrees and the third angle is 40 degrees,

70 + 70 + 40=180

One angle of 70 degrees and two angles that are 55 degrees each.

70 + 55 +55 =180

Answer:

Step-by-step explanation:The total of all 3 angles in every triangle equals 180 degrees. An isosceles triangle has two side lengths equal and two angle degrees equal.

I believe x is 8

In a triangle, its midsegment is (2x + 8) units long and its parallel side is (5x - 9) units long. How long is the midsegment?

Answers

Answer:

The midsegment is 58 units long.

Step-by-step explanation:

Midsegment Theorem:

It states that the length of the midsegment is half the length of the parallel side.

In this question:

Midsegment: 2x + 8

Parallel side: 5x - 9

Parallel side is double the midsegment. So, we use this to find x:

[tex]5x - 9 = 2(2x + 8)[/tex]

[tex]5x - 9 = 4x + 16[/tex]

[tex]x = 25[/tex]

Midsegment:

[tex]2x + 8 = 2(25) + 8 = 50 + 8 = 58[/tex]

The midsegment is 58 units long.

Actually Welcome to the Concept of the ratio and percentages.

let's be the total kalguksu soup quantity be x

hence, 60% of x = 24 cups, so we get as

===> 60/100 * x = 24

=> 0.6*x = 24

hence, x ==> 24/0.6

=====> x = 40 cups

hence the answer is 40 cups are in total kalguksu soup.

Read the passage.A Flag with 50 StarsThe first American flag to have red and white stripes and white stars on a blue field was flown in 1776, shortly after the United States declared its independence from Great Britain. Legend has it that a Philadelphia seamstress named Betsy Ross was hired by George Washington himself to create this flag. There is no evidence that this legend is true, and no one knows for certain who made the first flag, which had 13 stars and 13 stripes. However, we know for a fact that the first flag to have 50 starsthe one we have todaywas designed by a high school student. In 1958, Bob Heft was a 17-year-old student at Lancaster High School in Ohio. At that time, the United States had only 48 states but was on the verge of accepting two more: Alaska and Hawaii. The U.S. flag at the time had six neat rows of eight stars each. What would be the best way to add two more stars while keeping the arrangement neat and orderly? This was the question that Bobs history teacher posed to the class. The teacher gave the students an assignment: design a flag with 50 stars. Bob spent hours in the attic of his house, cutting up a 48-star flag and rearranging the stars until they fit just right. He was pleased with his solution to the problem, but his teacher found it less than perfect and gave him a B minus. Outraged, Bob told his teacher that he was going to send his design to his member of Congress, Walter Moeller. His teacher replied that if Bobs design was accepted as the new flag, he would be more than happy to change the grade to an A. A year later, Bob had graduated and was working as a draftsman when he received a call at work. He never would have imagined a call from President Eisenhowerbut that's who it was! Now that Alaska and Hawaii had been admitted as states, Congressman Moeller had succeeded in having Bob's design chosen as the new U.S. flag. Bob Heft was invited to Washington, D.C., for a ceremony during which his design was officially adopted as the new flag of the United States.Read the excerpt from A Flag with 50 Stars. Now that Alaska and Hawaii had been admitted as states, Congressman Moeller had succeeded in having Bob's design chosen as the new U.S. flag.How do these sentences contribute to the text?They imply that the people of Alaska and Hawaii prefer Bob's design over other options.They show it takes several years for the U.S. government to approve a new flag design. They develop the idea that Bob's design is exceptional, despite what his teacher thought.They develop the idea that, without Congressman Moeller, there would not be a new U.S flag. 1.
