The correct answer is below:

Answer:

Step 1, all the exponents are increased by 4

Step-by-step explanation:

The first incorrect step occurred in Step 1, where all the exponents were increased by 4.

This is mathematically incorrect due to exponential rules. When distributing exponents inside parentheses, we have to multiply the existing exponents inside the parentheses by the exponent outside the parentheses.

For example, (x²)³ is not x²⁺³, but rather, x⁽²⁾⁽³⁾.

We multiply the exponents instead of adding them together.

Therefore, the correct Step 1 should multiply all the variables' exponents by 4.

Steps 2 and 3 are correct since we do add the exponents when multiplying exponents with the same base, and we do subtract exponents with the same base when dividing.

Step-by-step explanation:

The volume of the prism is 160 m³ and the correct equation is V = 8 × 4 × 5.

A linear equation for the given case can be written by assuming any variable as the unknown quantity. Then, as per the given data the required operations are done and it is equated to some value.

The length, width and height of the rectangular prism are given as 8m, 4m and 5m respectively.

Since, the volume of the prism is given as the product of its length, width and sides.

For the given prism the volume can be obtained as,

V = 8 × 4 × 5

⇒ V = 160 m³

Hence, the correct equation is given as  V = 8 × 4 × 5.

Answer:

P = 0.001625

yes, it did

Step-by-step explanation:

given data

affective ones = 2%

spark plugs = 8000

defective = 13

to find out

experimental probability that the next sparkplug will be defective and Did the mannufacturer reach its goal

solution

we know that there are 13 are defective out of 8000

so P = 13 ÷ 8000

P = 0.001625

so  that P( the next sparkplug will be defective) is = 0.001625

and

yes, we mannufacturer to reach goal

because 0.001625 < .02

So, the goal is reached as the experimental probability is less than 2%

Answer:

y = 3x + b

Step-by-step explanation:

The slope of y=mx+3 that passes through (-3,4) is found like this:

1. Substitute the y and x values in (4 = m*(-3) + 3).

2. Simplify by subtracting 3 from each side (1 = m*(-3)).

3. Simplify by dividing each side by -3 (-1/3 = m).

Since the slope of perpendicular lines are negative reciprocals, the slope of the perpendicular line is 3.  The y-intercept can be anything and it will still be perpendicular.

Answer:

34.06°

Step-by-step explanation:

25 is the length of the hypotenuse side and 14 is the length of the opposite side.

Therefore, you will need to use sine to work out the missing angle.

sinx = opp / hyp

sinx = 14 / 25

x = sin ^ -1 (14 / 25)

= 34.06°

Answer:

*The amount the customer paid, in dollars, for the chocolate in the bag is 9x.

*The total weight of the bag of chocolate and almonds is x + y.

*The cost per pound of the almonds is $11.

Step-by-step explanation:

A customer paid 9x + 11y dollars for a bag that contains x pounds of chocolate and y pounds of almonds.

From the above questions, we know that:

The weight of Chocolate = x pounds

The weight of Almonds = y pounds

The cost per Chocolate = $9

The cost per Almonds = $11

Therefore, the three statements that are true are:

* The amount the customer paid, in dollars, for the chocolate in the bag is 9x.

* The total weight of the bag of chocolate and almonds is x + y.

*The cost per pound of the almonds is $11.

A function shows the relationship between at least two variables. There are several ways to represent a function; some of them are:

Tables

The following table shows the relationship between two variables x and y

[tex]\left[\begin{array}{cccccc}x&1&2&3&4&5\\y&2&4&6&8&10\end{array}\right][/tex]

Equations

Notice that the y values of the above table are twice the corresponding x-values.

So, the equation can be represented as:

[tex]y = 2x[/tex]

Graphs

See attachment for the graph of [tex]y = 2x[/tex]

Verbal

As stated above, the value of y is twice the value of x.

The above statement is a verbal representation of a function

Hence, a function can be represented with a table, graph, equation and verbally.

Step-by-step explanation:

cost of food booths = 16 * (100 + 9d) = 1600 + 144d

cost of game booths = 23 * (95 + 5d) = 2185 + 115d

total = 1600 + 2185 + 144d + 115d = 3785 + 259d

Step-by-step explanation:

Answer:

y = 8/6x + 10/3

Step-by-step explanation:

You find the slope (m) first which is

Change of y over change of x

(6) - (-2)   over   (2)- (-4)

8/6 = m

Then you plug it into the equation y = mx + b

y = (8/6)x + b

Now you pick any of the set of points to plug in for x and y to solve for b

(6) = (8/6)(2) + b

6 = 8/3 + b

b = 10/3

Then plug into the equation for just m and b to get the equation of the line that passes thru both sets of points.

y = 8/6x + 10/3
