What is the slope, m, of the line represented by the table below?
A. -4
B. -1/3
C. 1/3
D. 3

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.

Answer:

A. [tex]\frac{9}{5}[/tex]

Step-by-step explanation:

-[tex]\frac{1}{4}[/tex] ( -[tex]\frac{4}{5}[/tex] / [tex]\frac{2}{3}[/tex] ) 6

Note that when dividing fractions, you can flip one and multiply instead to gte the same answer.

-[tex]\frac{1}{4}[/tex]*6( -[tex]\frac{4}{5}[/tex] * [tex]\frac{3}{2}[/tex] )

[tex]\frac{-6}{4}[/tex] ( [tex]\frac{-4*3}{5*2}[/tex] )

[tex]\frac{-6}{4}[/tex] ( [tex]\frac{-12}{10}[/tex] )

[tex]\frac{-6*-12}{4*10}[/tex]

[tex]\frac{72}{40}[/tex]

Divide top and bottom by 8.

[tex]\frac{72/8}{40/8}[/tex]

[tex]\frac{9}{5}[/tex]

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].

Answer:

A

Step-by-step explanation:

290g+450g+670g = 1,410g

1g = 0.001kg

1410g = 1.41kg

Answer:

A.1.41

Step-by-step explanation: 290+450+670=1410 grams. One kilogram is 1000 grams so 1410 grams is 1.41 kilograms.

Answer:

216 is the area

hope this helps

have a good day :)

Step-by-step explanation:

Answer:

if it's area, then:

area = 216 cm²

Step-by-step explanation:

area = 1/2bh = 1/2(27)(16) = 216 cm²

Answer: A

Step-by-step explanation: The only one that’s not included in the pattern

Answer:

answer a.

Step-by-step explanation:

You can see that the shaded parts are moving counterclockwise (I think) so if you continue the pattern then you will get A.

Answer:

The People

Step-by-step explanation:

The first part of the preamble states, "We the People of the United States, in Order to form a more perfect Union..." The United States government was built by the people, for the people. It was important to the founding fathers that there could be a democracy where the people could hold the power of the government. So, they wrote this into the constitution and preamble.

Answer:

2x+ (x-1) = 8

Simplified

3x-1 =8

Step-by-step explanation:

y=x−1

2x+y=8

Take the first equation and everywhere you see y in the second equation substitute x-1

2x+ (x-1) = 8

You can simplify

2x+x-1 =8

3x-1 =8

If you want to solve

3x-1+1 =8+1

3x= 9

Divide by 3

3x/3 =9/3

x=1

Then solve for y

y = x-1

y = 3-1

y=2

Answer:

2(x+3)²+12=4

2x+6²+12=4

2x+36+12=4

2x=4-36-12

2x=-44

2x/2x=-44/2x

x=-22

Answer:

148.92 is the area of the triangle

hope this helps

have a good day :)

Step-by-step explanation:

Answer:

If it's area, then:

area = 148.92 in²

Step-by-step explanation:

area = 1/2(20.4)(14.6) = 148.92 in²

Answer:

i dont know but i need points lol

Step-by-step explanation:

1. Diameter= 14-2-2 = 10 feet

2. 11x 14 = 154

1/2 x 3.14 x 5^2 = 39.25

Area = 154-39.25 = 114.75 square feet

3. 114.75 x 1.50 = $172.13

Answer: 360000

Step-by-step explanation:yes because they want to reach to faster before the others to come and they have lot of feet that they can use

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

Answer:

3/16

Step-by-step explanation:

i took the test

Answer:The answer is C

Step-by-step explanation:because to slove from range you have subtract the highest number from  the lowest number from each team.Meaning ,that Team A range is 45 ,and Team B is 49 whice means that Team B is automatically the highest,so team B had more scores than team A.

Answer:

Solutions given;

Using cosine rule

b²=a²+c²-2*a*c*cos B°

b²=15²+8²-2*15*8*cos39

b²=102.48

b=[tex] \sqrt{102.48} [/tex]

b=10.12

b=10.1

Using sine rule

[tex] \frac{sin A}{BC} = \frac{sin B}{AC} =\frac{sin C}{AB} [/tex]

[tex] \frac{sin 29°}{15} =\frac{sin C}{8} [/tex]

Doing criss cross multiplication

Sin C=[tex] \frac{sin 29°}{15} ×8[/tex]

m<C=Sin -¹(0.29)

m<C=14.98

m<C=15°is a required answer.
