Answer:

9. obtuse isosceles

10. equiangular equilateral

For 10., it is also acute equilateral, but if you can pick only one answer, go with the answer above which is more descriptive.

Step-by-step explanation:

Two sides are congruent. The third side is not congruent to the other two.

According to sides: isosceles triangle.

One angle is obtuse.

According to angles: obtuse triangle

10.

All sides are congruent.

According to side: equilateral triangle.

All angles are congruent, and each angle measures 60 deg. All angles are acute.

According to angles: equiangular triangle

According to angles: acute triangle.

Question 3. The true statements are:
4g2 – g = g2(4 – g) ⇒ should be: 4g² - g = g(4g - 1)
9g3 + 12 = 3(3g3 + 4) ⇒ should be: 9g³ + 12 = 3(3g³ + 4) TRUE
24g4 + 18g2 = 6g2(4g2 + 3g) ⇒ should be: 24g⁴ + 18g² = 6g²(4g² + 3)
35g5 – 25g2 = 5g2(7g3 – 5) ⇒ should be: 35g⁵ - 25g² = 5g²(7g³ - 5) TRUE

Scores of an IQ test have a bell-shaped distribution with a mean of 100 and a standard deviation of 17. What percentage of people has an in score between 83 and 117

Answers

To find the percentage of people with an IQ score between 83 and 117, we need to find the area under the bell-shaped curve between these two scores.

First, we need to standardize the scores by subtracting the mean from each score and dividing by the standard deviation.

For a score of 83:

Standardized score = (83 - 100) / 17 = -1

For a score of 117:Standardized score = (117 - 100) / 17 = 1

Now, we can find the area under the curve between these standardized scores using a standard normal distribution table or calculator.

Using a standard normal distribution table, we can find the area for a standardized score of -1 as 0.1587. This represents the percentage of people below a score of 83.

Similarly, the area for a standardized score of 1 is 0.8413, representing the percentage of people below a score of 117.

To find the area between these two scores, we subtract the area below 83 from the area below 117:

0.8413 - 0.1587 = 0.6826

So approximately 68.26% of people have an IQ score between 83 and 117.

The body of a person who weighs 50 kilograms contains around 2 × 10^2 grams of sodium chloride. How much sodium chloride is contained in the bodies of 1.8 × 10^3 people who each weigh 50 kilograms? Represent the answer in scientific notation.

Answers

we can solve this problem by the rule of three.
1 person------------------2*10² g of sodium chloride.
1.8*10³ people---------- x

x=(1.8*10³ people * 2*10² gr of sodium chloride) / 1 person=3.6*10⁵ g of sodium chloride.

answer: 3.6*10⁵ g of sodium chloride.

Answer:

Answer: 3.6*10⁵ g of sodium chloride.
