Answer:

Step-by-step explanation:

According to the definition of the function each domain should have a uniqe range.

We have same domain of 4 with two different ranges 2 and 3.

It makes the relationship one-to-many, which can't be a function

Step-by-step explanation:

The rule is

A relation is said to be a function if every domain has an unique range

Here

f(4) has 2 values 2,3 hence it's not an function

The amount of square yards of fabric that Margo used to make each dress is; 1.5 sq. yds

We are told that;

Last year, she used 78 yd² to make 52 dresses

We are told that she used the same amount of square yards for each dress.

Thus, to find the  square yards of fabric that Margo used to make each dress, we just divide 52 by 78.

Square yards used for each fabric = 78/52 = 1.5 sq. yds

Answer:

$5.63

Step-by-step explanation:

We can form a ratio to solve this problem

12:3.75

18/12 = 1.5 times rate

1.5(12):1.5(3.75)

18:5.625, rounded to 5.63

Answer:

$5.63

Step-by-step explanation:

Divide the dollar over the apple.[tex]$3.75/12=0.3125[/tex] cent per apple. Now multiply it with 18 apples.

[tex]18 apples * 0.3125 cent = $5.625[/tex] rounding that up to cents so $5.63

First rewrite the equation in slope intercept form

slope intercept form: y = mx + b [ where m is slope and b is y-intercept ]

[tex]\rightarrow \sf 8y = -2x+32[/tex]

[tex]\rightarrow \sf y =\dfrac{ -2x+32}{ 8}[/tex]

[tex]\rightarrow \sf y =\dfrac{ -2x}{ 8} + \dfrac{32}{8}[/tex]

[tex]\rightarrow \sf y =\dfrac{ -1}{ 4}x + 4[/tex]

comparing with y = mx + b

x-intercept:          ( then y will be 0 )

[tex]\hookrightarrow \sf -2x + 32 = 0[/tex]

[tex]\hookrightarrow \sf -2x = -32[/tex]

Range for Arnold: 18; IQR: 12

Range for Jackson: 20; IQR: 13

Jackson's had the greatest spread.

Arnold's middle 50% had the least spread

Range = Maximum value - minimum value

Interquartile range (IQR) = Q3 - Q1

Range and IQR are both measures of variability. The larger the value, the more spread the data values in a data set are.

Range for Arnold's training times = 102 - 84 = 18

Range for Jackson's training times = 103 - 83 = 20

Therefore, Jackson's training times had the greatest spread.

Interquartile range for Arnold's training times = Q3 - Q1 = 99 - 87 = 12

Interquartile range for Jackson's training times = Q3 - Q1 = 100 - 87 = 13

Thus, Arnold's middle 50% of his training times had the least spread.

The range and interquartile range tells us that, Arnold's training times are more consistent than Jackson's.

Answer:

Step-by-step explanation:

In this question we have given with an equation that is 4 ( 5x - 2 ) = 2 ( 9x + 3 ). And we are asked to solve this equation that means we have to find the value of x.

Solution : -

[tex] \quad \longrightarrow \: 4 ( 5x - 2 ) = 2 ( 9x + 3 )[/tex]

Step 1 : Removing parenthesis :

[tex] \quad \longrightarrow \:20x - 8 = 18x + 6[/tex]

Step 2 : Adding 8 from both sides :

[tex] \quad \longrightarrow \:20x - \cancel{ 8 }+ \cancel{8} = 18x + 6 + 8[/tex]

On further calculations we get :

[tex] \quad \longrightarrow \:20x = 18x + 14[/tex]

Step 3 : Subtracting 18 from both sides :

[tex] \quad \longrightarrow \:20x - 18x = \cancel{18x }+ 14 - \cancel{18}[/tex]

On further calculations we get :

[tex] \quad \longrightarrow \:2x = 14[/tex]

Step 4 : Dividing with 2 on both sides :

[tex] \quad \longrightarrow \: \frac{ \cancel{ 2}x}{ \cancel{2}} = \cancel{\frac{14}{2} }[/tex]

On further calculations we get :

[tex] \quad \longrightarrow \: \blue{\boxed{ \frak{x = 7}}}[/tex]

Verifying : -

We are verifying our answer by substituting value of x in given equation. So ,

Therefore, our value for x is correct .

Answer:

[tex] \: [/tex]

Step-by-step explanation:

In the above question, we have to solve the equation and find the value of x. So,

[tex] \\ {\longrightarrow \pmb{\sf {\qquad 4(5x-2)=2(9x+3) }}} \\ \\ [/tex]

Using distributive property we get :

[tex] \\ {\longrightarrow \pmb{\sf {\qquad 20x-8=18x+6 }}} \\ \\ [/tex]

Adding (-18x) to both sides we get :

[tex]\\ {\longrightarrow \pmb{\sf {\qquad 20x-8 + ( - 18x)= \cancel{18x}+6 + \cancel{( - 18x) }}}} \\ \\ [/tex]

[tex] {\longrightarrow \pmb{\sf {\qquad 2x-8=6 }}} \\ \\ [/tex]

Now Adding 8 to both sides we get :

[tex]\\ {\longrightarrow \pmb{\sf {\qquad 2x-8 + 8=6 + 8 }}} \\ \\ [/tex]

[tex]{\longrightarrow \pmb{\sf {\qquad 2x=14 }}} \\ \\ [/tex]

Dividing both sides by 2 we get :

[tex] \\ {\longrightarrow \pmb{\sf {\qquad \frac{2x}{2} = \frac{14}{2} }}} \\ \\ [/tex]

[tex]{\longrightarrow \pmb{\frak {\qquad x=7 }}} \\ \\ [/tex]

Answer:

1/12 + 3/12 = 4/12 (or 1/3)

Step-by-step explanation:

we want to express

1/12 + 1/4 as 1/12 + something / 12

1/12 + 1/4 = 1/12 + something/12

we already have the 1/12 part, so we're left with

1/4 = something / 12

first, we can calculate (denominator we want) / (denominator we have) = 12/4 = 3

then, we want to multiply our current value (1/4) by our result of the multiplication divided by itself.

3/3 = 1

1/4 = 1/4 * 1 = 1/4 * 3/3 = 3/12

thus, our second value is 3/12

we then have 1/12 + 3/12

if we have the same denominators, we can simply add the numerators up

1/12 + 3/12 = (1+3)/12 = 4/12

Answer: -5.6

Answer: Angle 1 is 117.6⁰, the alternate angle to 1 is also 117.6⁰

X is 24.8

The Angle 2X + 12.8 = 62.4⁰, the alternate angle to it is also 62.4⁰

Step-by-step explanation: Angle (2X + 12.8 )forms 1180⁰ with Angle 1

180⁰- 117.6⁰ = 2X + 12.8

62.4⁰ = 2X + 12.8

Subtract 12.8 from both sides

49.6 = 2X

X is 24.8⁰

Answer:

Approximately normal

Mode: 4

Range:9

Step-by-step explanation:

The data is pretty evenly spread, the data isn’t pushed to the left or right giving the answer of approximately normal.

Mode: The number that occurs the most is the mode. This means that 4 would be the answer because it has the most dots.

Range: To find the range subtract the smallest number from the biggest number. In this case you would get 9-0 (this is because no data is recorded for 10) which equals 9.

Remark

Normally you would have to make sure that the bottoms of each fraction to be added would be the same. In this question, they are, so nothing further to getting the bottoms the same has to be done,

Solution

answer = 7 / 16 + 3 / 16

answer = (7 + 3) / 16

answer = 10/16        

Both top and bottom are even numbers so you can divide both top and bottom by at least 2.

10/2 = 5

16 / 2 = 8

So answer = 5/8
