The crafter should sell the item for $1.44 to make a 20% profit

The amount of profit to be made is 20%

100% + 20%

= 120%

= 120/100

= 1.2

The amount the item can be sold can be calculated as follows

1.20 × 1.2

= 1.44

Hence the item will be sold for $1.44 to make a profit of 20%

Explanation:

The steps to construct an inscribed square are:

0. Draw the diameter of the circle

1. Place the compass on the point where the circle and diameter intersect

2. Swing an arc the length of the radius from the point on the circle

3. Repeat 2 and 3 for the other intersection point

4. Draw a line through the intersections of the arcs from the previous steps

5. Draw lines between the points on the circle

The step from the options that's not here is swing two arcs above and below the diameter

Answer:

Swing two arcs above and below the diameter

Finally we obtain that the given expression is equal to 6.

The value of the estimated standard error for the following set of D scores 4, 8, 4, 4 is 1.

The standard deviation of a statistic's sample distribution, or an approximation of that standard deviation, is the statistic's standard error. The term "standard error of the mean" is used when referring to a statistic that is the sample mean.

Consider the following set of D scores,

4, 8, 4, 4

We will calculate ∑D and ∑D² to find the SS for the D scores.

Therefore,

∑D = 4 + 8 + 4 + 4

∑D = 20

∑D² = 4² + 8² + 4² + 4²

∑D² = 16 + 64 + 16 + 16

∑D² = 112

Now, the formula for the standard score is given as:

[tex]SS=\sum D^2- \frac{(\sum)^2}{n}[/tex]

SS = 112 - [ (20)² /4 ]

SS = 112 - 100

SS = 12

Now,

[tex]S_{D}=\sqrt{\frac{SS}{n-1} }[/tex]

[tex]S_{D}=\sqrt{\frac{12}{4-1} }[/tex]

[tex]S_{D}=\sqrt{4}\\ S_{D}=2[/tex]

[tex]S_{\overline D}=\frac{S_{D}}{\sqrt{n} }[/tex]

[tex]S_{\overline D}=\frac{2}{\sqrt{4} }[/tex]

[tex]S_{\overline D}=\frac{2}{2}=1[/tex]

Hence, the standard error of the set of D scores is 1.

Times the two whole number by five, add the result to top number, divide by denominator.

The continuous function that generated the following table of values is has more than one x-intecept.

A continuous function is one whose graph is continuous throughout without any interruptions or leaps, as the name suggests. In other words, we claim that a function is continuous if we are able to draw its curve (graph) without ever picking up the pencil. Calculus students must learn about a function's continuity because without it, a function cannot be differentiable.

Table

x        y

0      -3

1      -2

5      0

11    7

An x-intercept results whenever the function crosses the x-axis and changes sign. Additionally, when the function's value is zero, it acts as an x-intercept.

In the tables, there are two sign changes (from +4 to -3 and from -3 to +2). It also has one value of zero, and this function has a minimum of three x-intercepts. Therefore, you can infer that the choid b is accurate.

The function has more than one x-intecept.

The water pressure on the submerged object is given by d = P ÷ 64

Pressure is the force that is applied perpendicularly to the area across which it is applied to an object's surface (symbol: p or P).

Gauge pressure, frequently written gage pressure, is the measurement of pressure in proportion to the atmosphere.

Various units are used to express pressure.

The pound-force per square inch (psi), which is equivalent to one newton per square meter (N/m2) in the SI, is the standard unit of pressure in the imperial and American customary systems.

A unit of force is divided by a unit of area to arrive at some of these findings.

a. The given formula is is P=64d

or , d = P ÷ 64

b. at a pressure of 672

d = 672  ÷ 64

or, d = 10.5 feet

Therefore the pressure is 672 pounds per square foot at a depth of 10.5 feet.

The quantity of the new sweaters at a price of $12 is gotten using the slope of 3 to be 36 sweaters

given data

Pa = $120

Qa = 40

Pb = $12

slope of the supply curve is m=3

The slope represents the relationship between the the input variable and the output variable.

The input variable is the price while the output variable is the quantity supplied.

The slope is the factor that multiplies the input to get the output, we therefore solves as follows

Multiplying in math is the same as adding equal groups. The number of items in the group grows as we multiply. Parts of a multiplication issue include the product, the two factors, and the product. The factors in the multiplication problem 6 x 9 = 54 are the numbers 6 and 9, and the product is the number 54.

how the heak is this a colledge question*_* i learned this in 2nd grade lol

We have rewritten 23 + 42 = 65 as 23 + 42 = 65 using the Commutative Law of Addition.

A number system is defined as a system of writing to express numbers.

The Commutative Law of Addition states that changing the order of the addends does not change the sum.

a+b=b+a

Therefore, we can rewrite 23 + 42 as 42 + 23, and the equation becomes:

42 + 23 = 65

or 42+23=23+42

So, we have rewritten 23 + 42 = 65 using the Commutative Law of Addition.

Hence,  we have rewritten 23 + 42 = 65 as 23 + 42 = 65 using the Commutative Law of Addition.

The maximum height reached by the ball is 22 feet

The ball stayed in the air for 1 second

A function can be defined as a rule, law or expression that shows the relationship between two identifiable variables:

Given the function:

h(t) = -16t² + 32t + 6

Where;

To determine the maximum height in feet that the ball reached, we would be required to substitute the value of t as 1

We have:

h(1) = -16(1)² + 32(1) + 6

expand the bracket

h(1) = -16 + 32 + 6

Add the values

h(t) = 22 feet

To determine the time, we have;

-16t² + 32t + 6 = 22

-16t² +32t + 6 - 22 = 0

Add like terms

-16t² +32t - 16 = 0

Factorize further

-16t² + 16t + 16t - 16 = 0

Factorize in pairs

16t( t - 1) + 16 ( t - 1) = 0

Then,

t - 1 = 0

t = 1 second

A general solution of a trigonometric function gives all possible solutions of the trigonometric functions and comprises of the integer n.

The given function is presented as follows;

f(x) = 2•sin(x)

The solution of the function is given by the point where f(x) = 0 as follows;

When f(x) = 0

2•sin(x) = 0

sin(x) = 0

Therefore;

x = arcsin(0)

sin(2•π) = 0

sin(π) = 0

Therefore, the solution is the set of whole number multiples of pi

Which gives;

x = -(2•π•n - π) and x = 2•π•n
