A Sociology student investigated the association between a country's Literacy Rate and Life Expectancy, and then drew the conclusions listed below. Explain why each statement is incorrect. (Assume that all the calculations were done properly.)
a) The $$R^2$$ of 64% means that the Literacy Rate determines 64% of the Life Expectancy for a country.
b) The slope of the line shows that an increase of 5% in Literacy Rate will produce a 2-year improvement in Life Expectancy.

Answers

Solution :

The term 'literacy rate' provides the ability of a person who is from a definite age group can read or write.

a). [tex]$R^2$[/tex] does not determine the rate at which the variable explains another, but it explains the amount the amount of variability in one of the variables as explained by the other variable.

b). The slope given provides an expected improvement but it cannot guarantee the improvement. The value may be less or it could be more also.

The regression model provides the prediction and not the actual values.

Express 315 as a percentage of 420​

Answers

Step 1: Multiply the number being expressed to 100
315: 420 • 100 = 75

Step 2: Multiply the expresser to 100
(315 • 100): 420 = 31500

Step 3: Divide the result by the number being expressed
31500/420 = 75

What is the surface area of this triangular prism?

Answers

11 ft I guess not sure tho

The surface area of this triangular prism is,

Surface area = 228 ft²

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

Dimensions of the triangular prism are,

6.5 ft

6 ft-

11 ft

5 ft

Now, We know that;

The formula that is used to calculate the surface area of a triangular prism is,

Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area)

Hence, We get;

The surface area of this triangular prism is,

Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area)

Surface area = (5 + 6.5 + 6.5) × 11 + (5 × 6)

                    = 198 + 30

                    = 228 ft²

Thus, The surface area of this triangular prism is,

Surface area = 228 ft²

Kyle and Jorge play for a major league baseball team.
• Kyle has hit x number of home runs this season.
• Jorge has hit 4 times the number of Kyle's home runs.
Together they have hit 45 home runs.
How many home rns has Kyle hit?

Answers

Answer:
15
Explanation

The number of home runs hit by Kyle is 9.

Number of home runs by Kyle =x

So, the number of home runs by Jorge = 4x

What is the sum of x and 4x?

The sum of x and 4x is 5x.

According to the question, together they have hit 45 home runs.

This means, x+4x=45

5x=45

x=9

So, the number of home runs by Kyle =9

the number of home runs by Jorge =36

Hence, the number of home runs hit by Kyle is 9.

A math teacher at George Washington Middle School asked boys in the 6th and 7th grades to report their shoe size. She used the results to create these histograms

Which conclusion best supported by the histograms?
A as boys get older, shoe sizes become more normally distributed with fewer large outliers.
B As boys get older, shoe size range, defined by the minimum and maximum, decreases
C As boys get older, shoe sizes increase and the distribution remains relatively unchanged.
D As boys get older, shoe size distribution becomes more spread with more large outliers

Answers

Answer:

As boys gets older, shoe sizes becomes more normally distributed with fewer large outliers.

Step-by-step explanation:

A visual analysi ls of the histogram distribution provided, we can observe that size distribution of 6 graders is positively skewed (right tailed) as outliers seems more to the right(large sizes). However, the second graph is balanced with a normal or symmetric distribution representing older age (7th graders). Hence, we can conclude that as the boys gets older, they attain normality in terms of their shoe sizes. And the outliers which are characterized by the first histogram having vanished or reduced.

I can't give u the answer but I can give u how to find the part of the triangle.

Area of a triangle is Base × High ÷2

You want to start by finding the area of each individual section. Start with the rectangle, you would do Length x Width (LxW) so 4x12 = 48. Then you find the area of the triangle. The formula for this is h b/2 so b (base) divided by 2 and then you multiply that by h (height). In this equation that would be 5/2=2.5 x (3+4)= 2.5 x 7 = 17.5. The last thing to do is find the area of the half circle. You start with the area of a circle formula which is (pi)r^2 (I don’t have a pi symbole so I’m just writing pi) pi =3.14 and r (radius). In the equation we have 4 ft. That would be the diameter. To get the radius we just need to divide the diameter, which in this case is 4, by 2. (4/2) were left with 2. Then we just plug in our numbers and we have pi2^2. (3.14x2)^2 =12.566. This is the area of the whole circle but since we only have half a circle, we divid it by two. So we have 6.283. Now we just add all the areas we got together for the full area of the shape. 17.5 + 48 + 6.283 = 71.783.

What is the value of k?

Answers

9514 1404 393

Answer:

  k = 10

Step-by-step explanation:

The useful shortcut* here is that the external angle is equal to the sum of the remote internal angles.

  115° = (4k+5)° +(6k+10)°

  100° = 10k° . . . . . . collect terms, subtract 15°

  k = 10 . . . . . . . . . . divide by 10°

_____

* I call it a shortcut because you can get there from the relations ...

the sum of angles in a triangle is 180°a linear pair has a sum of 180°

If we call the internal angles X, Y, and Z, then we have ...

  X + Y + Z = 180° . . .  triangle sum relation

  Y + 115° = 180° . . . . . linear pair relation

Equating the expressions for 180° gives ...

  X + Y + Z = Y + 115°

  X + Z = 115° . . . . . . . . . subtract Y from both sides

❀ Here, We are given relation from A to B [ Suppose ] & We have to identify whether they are function or not from the relation A to B.

{ ( 1 , 1 ) , (2 , 2 ) , ( 3 , 3 ) , (4 , 4 ) , ( 5 , 5 )}

⇢ This is a function from A to B because every element of Set A has unique image in set B.

⇢ This is not a function because two of the elements of Set A ( 1 & 4 ) are associated to elements -1 , 1 & 2 , -2 respectively of Set B

{ ( 2 , 1 ) , (2 , 2 ) , (2 , 3 ) , (2 , 4 ) , (2 , 5 )

♨ Q. What is function ? How can we identify whether the given relation is a function ?

⟶Function is a special type of relation. Function is the refinement of relation. In a relation from A to B , every element of Set A has only one ( distinct ) image in B. In other words , if no two different ordered pairs have the same first component , then it is a function.
