Answer 1

Answer:

9 x 7 = 63

6.8 x 10 = 68 divided by 2 = 34

13 + 15 = 28, 28 x 6 = 168 divided by 2 = 84

The Trapezoid.

21.6 divided by 3 = 7.2 I THINK (remember I don't really know if this is the way you learned because i dont think i've learned this)

(I split it into 2 triangles)

2 + 2 = 4

4 x 4 = 16 divided by 2 = 8

4 x 3.2 = 12.8 divided by 2 = 6.4

8 + 6.4 = 14.4

B is your answer

Answer:

3/16

Step-by-step explanation:

The radii of the three circles appear to be in the ratios ...

5 : 10 : 20 = 1 : 2 : 4

Then the areas of the circles will be in the ratios that are the square of these:

1 : 4 : 16

The shaded area is the area of the middle-sized circle, less the area of the smaller circle, so is 4-1 = 3 "ratio units". The ratio of that area to the area of the largest circle is the probability of randomly choosing a point in the shaded area:

p(shaded) = 3/16

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

75 is the answer

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.

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.

Given:

[tex]sinh(f(x))=1+x^2[/tex]

To find:

The value of f'(x).

Solution:

Formulae used:

[tex]\dfrac{d}{dx}sinh(x)=cosh(x)[/tex]

[tex]\dfrac{d}{dx}x^n=nx^{n-1}[/tex]

[tex]\dfrac{d}{dx}C=0[/tex]

Chain rule:

[tex]\dfrac{d}{dx}[f(g(x))]=f'(g(x))g'(x)[/tex]

Where C is an arbitrary constant.

We have,

[tex]sinh(f(x))=1+x^2[/tex]

Differentiate with respect to x.

[tex]cosh(f(x))f'(x)=0+2x[/tex]

[tex]f'(x)=\dfrac{2x}{cosh(f(x))}[/tex]

Therefore, the required values is [tex]f'(x)=\dfrac{2x}{cosh(f(x))}[/tex].

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.
