Answer:

4 lemons per pitcher basically by looking at the graph you can determine each pitcher increased by a steady pattern of 4 lemons per pitcher.

Example: 2x=8, x=4, 2(4)=8, 8=8 true, the x and y value is cannot be 0 for this equation since no workers means no lemons. If I subtract back by -4 the graph would look like: 1 4, 0 0. Proving this. Also another example I can do is 3x=12, divide 3 by both side x=4, plug them in, 12=12 which is true. Keep in mind X means Pitcher so 4 is correct.

Oh yea less compilcated way is to just look a graph I did all those step to prove to you. Good luck!

Answer:

1365

Step-by-step explanation:

The number of ways in which you can choose r items as a set from n available items is given by n choose k which can be represented as
Here n = 15, r = 4

C(n, r)

C(n,r) = C(15,4)

The formula is

[tex]C(n,r) = \binom{n}{r} = \dfrac{n!}{( r! (n - r)! )}[/tex]

where ! represents factorial of a number

n! = n x (n-1) x (n-2) x.......x 3 x 2 x 1

So
[tex]C(15,4) = = \dfrac{15!}{( 4! (15 - 4)! )}\\\\ = \dfrac{15!}{4! \times 11! }\\\\\\= 1365[/tex]

Answer: 1365 combinations

Step-by-step explanation:

What you're looking for if the order doesn't matter is the number of combinations.

You can use this formula for it:

[tex]\frac{n!}{r!(n-r)!} \\[/tex]

Where n is the number of objects there are and r is the number of objects you take out.

We'll be using the variables:

n = 15

r = 4

Plug them in and solve:

[tex]\\\frac{15!}{4!(15-4)!} \\\\= \frac{15!}{4!* 11!} \\\\= \frac{1307674368000}{24 * 39916800} \\\\= \frac{1307674368000}{958003200} \\= 1365[/tex]

If the two angles are supplementary then the value of x is 33°.

Two angles that sum to a straight angle or 180° are called supplementary angles.

If the two given angles are supplementary then we can create a linear equation in x of the form:

m∠1+m∠2=180°

Substituting the values we get:

3x°+(x+48)°=180°

or, 4x°+48°=180°

or, 4x°=180°-48°

or,4x°=132°

or, x°=33°

Hence the value of x is 33°.

The slope of the line is 1/2.

The slope is a measure of the steepness of a line, or a section of a line, connecting two points.

Slope tells you how steep a line is, or how much y increases as x increases. The slope is constant (the same) anywhere on the line.

For example, for the equation y = 3x – 7, the slope is 3, and the y-intercept is (0, −7).

Given:

x=-5,0,4,8,13 and y=-7,3,11,19,29

To find the slope

m= (0-(-5))/(3-(-7))

m=0+5/ 3+7

m=5/10

m= 1/2

Hence, the slope is 1/2.

Answer: 1328

4*7^3 - 7*7 + 5 = 1328

The correct option is B) Collect variables terms on one side because there is one value for the variable.

The given equation in this case is,

18 = 2(4+x)

By using the Distributive property on the right side,

18 = 8 + 2x

After subtracting 8 from both sides ( Isolating variable x )

18 - 8 = 8 + 2x - 8

Compile similar terms,

10 = 2x

By dividing both sides by two ( Isolating variable x )

x = 5

After simplifying the algebraic expression 9 { 9 b - [ 2 - 3 ( 9 b - 5 ) ] }, we get the result as 324 b - 153.

We are given the algebraic expression:

9 { 9 b - [ 2 - 3 ( 9 b - 5 ) ] }

We need to simplify the expression.

For this, we will use the BODMAS rule.

B - Brackets

O - Of

D - Division

M - Multiplication

A - Addition

S - Subtraction

So, simplifying the expression, we get that:

9 { 9 b - [ 2 - 3 ( 9 b - 5 ) ] }

= 9 { 9 b - [ 2 - 27 b + 15 ] }

= 9 { 9 b - 2 + 27 b - 15 }

= 9 { 9 b - 2 + 27 b - 15 }

= 81 b - 18 + 243 b - 135

= 324 b - 153

Therefore, after simplifying the algebraic expression 9 { 9 b - [ 2 - 3 ( 9 b - 5 ) ] }, we get the result as 324 b - 153.

The height of the tree in the mural should be 22.5 feet.To determine the height of the tree in the mural, we can set up a proportion using the given information:

Devon's height in the mural: 4.5 feet

Devon's actual height: 6 feet

Tree's height in the mural: Unknown (let's denote it as x)

Tree's actual height: 30 feet

The proportion can be set up as follows:

(Devon's height in the mural) / (Devon's actual height) = (Tree's height in the mural) / (Tree's actual height)

(4.5 feet) / (6 feet) = x / (30 feet)

Now, let's solve for x by cross-multiplying:

4.5 feet * 30 feet = 6 feet * x

135 feet = 6x

Now, divide both sides of the equation by 6 to find x:

x = 135 feet / 6

x = 22.5 feet

So, the height of the tree in the mural should be 22.5 feet.

The slope of the line parallel to the line  –x + 3y = 6 is a 1/3 option (A) 1/3 is correct.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that:

The equation of the line:

–x + 3y = 6

Write the equation in standard form:

y = x/3 + 6/3

y = x/3 + 2

m = 1/3

The slope of the line parallel to the line  –x + 3y = 6

The probability that she selects all 4 blue disks is 0.0317.

The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

Now, according to the question;

There is a total of 4 blue disks.

There is a total of 3 yellow disks.

The formula for selecting the combination of 4 blue disks are

Probability = (combination for 4 blue)/ Total combination for 9.

The combination is given by the relation;

ⁿCₓ = n!/{x!(n-x)!}

All sets that √7 belong to irrational numbers

The number √7 is a number inside a square root. Also, note that the number 7 is a whole number, but not a perfect square. Therefore, by our rule, we have that √7 belongs to the set of real numbers and to the set of irrational numbers.

In mathematics, the irrational numbers (from in- prefix assimilated to ir- (negative prefix, privative) + rational) are all the important numbers that are not rational numbers.

That is, irrational numbers can't be expressed as the ratio of two integers. When the ratio of lengths of two line segments is a real number,  the road segments are also described as being incommensurable, meaning that they share no "measure" in common, that is,  there's no length ("the measure"),  regardless of how short,  that would be used to express the lengths of both of the two given segments as integer multiples of itself.

Among irrational numbers are the ratio π of a circle's circumference to its diameter, Euler's number e, the golden ratio φ,  and therefore the square root of two. In fact, all square roots of natural numbers,  aside from perfect squares, are irrational.

Like all real numbers, irrational numbers are often expressed in positional notation, notably as decimal numbers.  within the case of irrational numbers, the decimal expansion doesn't terminate, nor end with a repeating sequence.  

for instance, the decimal representation of π starts with 3.14159, but no finite number of digits can represent π exactly, nor does it repeat.

Conversely, a decimal expansion that terminates or repeats must be a  real number. These are provable properties of rational numbers and positional number systems and aren't used as definitions in mathematics.

Given; A certain group of test subjects had pulse rates with a mean of 78.9 beats per minutes.

Standard deviation of 11.7 beats per minute.

Range Rule of Thumb:

Standard deviation = Range/4.

Range = 4×SD.

           = 4×11.7

           = 46.8

The "usual" range for this situation is,

78.9-2(11.7) to 78.9+2(11.7) = 55.5 to 102.3

Significantly low will be less than 55.5

Sig high will be greater than 102.3

Pulse rate - Mean = 92.3 - 78.9 = 13.4                              

This value below mean

Then check 2×Standard deviation = 2×11.7= 23.4                              

This value is also below the mean value.

Significantly low values are 55.5 beats per minute or lower.

Significantly high values are 102.3 beats per minute or higher.
