jamal purchased a boat for 7/10 of the asking price of $18,950. He had to pay 6.5% sales tax. What was the amount of Jamal's bill?

Answers

Answer 1
Hello,

Since Jamal is only paying for 7/10 of the asking price, we can multiply it by 0.7.

0.7 x 18950 = 13265

Now, we have to add on the tax, so we should multiply the new amount by 1.065.

13265 x 1.065 = 14127.23

Jamal's bill will be $14,127.23

Good luck,
MrEQ

The mean score of a competency test is 82, with a standard deviation of 2. Between what two values do about 99.7% of the values lie?

Answers

99.7% encompasses about 3 standard deviations either side of the mean.

82 ±3*2 = (76, 88)

About 99.7% of the values lie between 76 and 88.

Answer:

99.7% lies between 76 and 88

Step-by-step explanation:

mean = 82, standard deviation = 2

3 standard deviation has 99.7%

so we need to find 3 standard deviation above and below the mean.

To find 3 standard deviation above the mean , we add standard deviation 2 with mean

82 + 2= 84 first SD

84 + 2= 86 second SD

86 + 2= 88 third SD

88 is the third SD above the mean 82

To find 3 standard deviation below the mean , we subtract standard deviation 2 from mean

82 - 2= 80 first SD

80 - 2= 78 second SD

78 - 2= 76 third SD

76 is the third SD below the mean 82

So , 99.7% lies between 76 and 88


What is the MAD of the data set?

{13, 6, 3, 7, 11}

Enter your answer in the box.

Answers

The MAD value of the given data set is "3.2".

Mean absolute deviation (MAD)

The average distance between each data value and the mean is defined as the mean absolute deviation of a data set. It is a measure of variation in a data set.

Calculation of the MAD value:

Given:

[tex]\to \{ 13, 6, 3, 7, 11\} \\\\[/tex]

Calculating the sum of the given value:

[tex]\to 13 + 6 + 3 + 7 + 11 = 40\\\\[/tex]

Calculating the average value:

[tex]\to \frac{40}{ 5} = 8\\\\[/tex]

Subtracting the average value from the given set:

[tex]\to 13 - 8 = 5\\\\\to 6 - 8 = | -2 | = 2\\\\\to 3 - 8 = | -5 | = 5\\\\\to 7 - 8 = | -1 | = 1\\\\\to 11 - 8 = 3\\\\[/tex]

Calculated set value:

[tex]\to 5, 2, 5, 1, 3\\\\[/tex]

Adding the set value:

[tex]\to 5 + 2 + 5 + 1 + 3 = 16[/tex]

Calculating the average value of the set:

[tex]\to \frac{16}{5} = 3.2\\\\[/tex]

So, the

[tex]\to \text{MAD} = 3.2[/tex]

Therefore, the final value of MAD is "3.2"

A rectangular prism has a volume of 60 in³. what is the least possible surface area of the prism?

and

A rectangular prism has a volume of 24 m³. What is the least possible surface area of the prism?

Answers

The rectangular prism that has the least surfacea area for a given volume is a cube. If the volume is given by V, the side length (s) will be
.. V = s³
.. ∛V = s

Then the surface area will be
.. A = 6*s²
.. A = 6(∛V)²
.. A = 6×V^(2/3)

a) For a cuboid with volume 60 in³, the least possible surface area is
.. A = 6*(60 in³)^(2/3) ≈ 91.957 in²

b) For a cuboid with volume 24 m³, the least possible surface area is
.. A = 6*(24 m³)^(2/3) ≈ 49.922 m²

In the coordinate plane, what is the length of the line segment that connects points at (4, −1) and (9, 7) ? Enter your answer in the box. Round to the nearest hundredth.

Answers

On this question is asked you to find the length of a line segment with endpoints (4,-1) and (9,7) and round it to the nearest hundredth. The only way to find the solution is by the use of the Distance Formula, which is d=√(x2-x1)^2+(y2-y1)^2.

d=√(x2-x1)^2+(y2-y1)2^2
d=√(9-4)^2+(7--1)^2
d=√(5)^2+(8)^2
d=√(25)+(64)
d=√89
d=9.43 units

The length of the line segment is 9.43 units.

Final answer:

The length of the line segment connecting points (4, -1) and (9, 7) in the coordinate plane is approximately 9.43 units, when rounded to the nearest hundredth.

Explanation:

To find the length of the line segment that connects the points (4, −1) and (9, 7) in the coordinate plane, we can use the distance formula which is derived from the Pythagorean theorem:

The distance (Δ) between two points (x1, y1) and (x2, y2) is given by:

Δ = √((x2 - x1)² + (y2 - y1)²)

Substituting the given coordinates:

Δ = √((9 - 4)² + (7 - (−1))²)

Δ = √(5² + 8²)

Δ = √(25 + 64)

Δ = √89

Using a calculator, we can find that:

Δ ≈ 9.43

Therefore, the length of the line segment is approximately 9.43 units, rounded to the nearest hundredth.

456 000 has been rounded to the nearest thousand.

find an inequality that you can use to disprove John statement. explain your thinking.

Answers

Try this inequality with 0 as the right side.

-x > 0

According to John, we multiply both sides by -1, and the inequality sign does not change direction, so we get this

x > 0

Let's use a number for x that makes the original inequality true.
Let x = -2.

-x > 0

-(-2) > 0

2 > 0

As you can see, -2 does work on the original equation.

Now let's try -2 in John's solution.

x > 0

-2 > 0 which is a false statement.

Now let's solve it again, but we will reverse the inequality symbol when we multiply both sides by -1.

-x > 0

x < 0

Try x = -2.

-2 < 0   which is true

Now it works.

John is incorrect.
If you multiply or divide an equation by a negative number, even if one of its sides is 0, you still must change the direction of the inequality symbol.

does the graph represents a function

Answers

You could use a simple pencil test to figure it out.
Place a pencil vertically on the paper, and move it left to right or vise-versa 
When moving it make sure the pencil doesn't hit two points at once if it does it is not a function, but this is not the case

This is a function

In this situation, we would use something called the vertical line test. In other words, if we can draw a vertical line that passes more than one point on the graph, then the relation is not a function.

If we use the vertical line test in this situation, it is not possible to draw a vertical line that passes through more than one point. Therefore, this does represent a function.

Jennifer Lopez met her 9 cousins at a family reunion. The number of male cousins (x) was 2 less than the number of females cousins (y)

Answers

Final answer:

To find the number of male and female cousins Jennifer Lopez met at a family reunion, we can set up a system of equations based on the given information. By solving the system, we can determine the values of the variables and find the answer.

Explanation:

The subject of this question is Mathematics and the grade level is Middle School. The question asks about the number of male and female cousins Jennifer Lopez met at a family reunion. Let's define the number of male cousins as x and the number of female cousins as y. From the given information, we know that x is 2 less than y.

So the equation can be written as: x = y - 2

Since Jennifer met a total of 9 cousins, we can write another equation: x + y = 9

Now we can solve this system of equations to find the values of x and y. Subtracting the first equation from the second equation, we get: (x + y) - (y - 2) = 9 - (y - 2)

Simplifying further, we have: x + 2 = 11 - y

Bringing the variables to one side, we get: x + y = 11 - 2

Combining like terms, we have: x + y = 9

Therefore, the value of x is 4 and the value of y is 5. So Jennifer Lopez met 4 male cousins and 5 female cousins at the family reunion.

2. WALKING Laura starts at the origin. She walks 8 units to the right and then 12 units up. How far away from the origin is she? Round your answer to the nearest tenth

Answers

Final answer:

Laura is approximately 14.4 units away from the origin after walking 8 units to the right and 12 units up, found by applying the Pythagorean theorem.

Explanation:

The question asks how far Laura is from the origin after walking 8 units to the right and 12 units up. To solve this, we can use the Pythagorean theorem, which is a fundamental principle in geometry that deals with the lengths of sides in a right-angled triangle. Here, we consider Laura's walk as the two perpendicular sides of a triangle, with her movement to the right representing the horizontal side (8 units) and her movement upwards representing the vertical side (12 units).

To find the distance (hypotenuse) from the origin, we apply the Pythagorean theorem as follows:

Calculate the square of both the horizontal and vertical distances: 8^2 = 64 and 12^2 = 144.Add the squares of the two sides: 64 + 144 = 208.Take the square root of the sum to get the hypotenuse: sqrt(208) ≈ 14.4 units.

Hence, Laura is approximately 14.4 units away from the origin, rounded to the nearest tenth.

find the greatest common factor of the following monomials 26n5 12n2

Answers

Final answer:

The greatest common factor of 26n^5 and 12n^2 is 2n^2, as the prime factor 2 and the variable n to the second power are the highest powers common to both monomials.

Explanation:

The greatest common factor (GCF) of two monomials, 26n5 and 12n2, is found by identifying the highest power of each prime factor that is present in both monomials. To find the GCF of 26 and 12, we factor both numbers into their prime factors:

26 = 2 × 1312 = 22 × 3

Since 2 is the only common prime factor between 26 and 12, and its lowest power in both numbers is 21, we take this as part of our GCF. For the variable part, we look at n5 and n2 and take the lowest power, which is n2. Hence, the GCF of 26n5 and 12n2 is 2n2.

a hippopotamus weighs 1.5 tons. What is its weight in ounces?

Answers

I used an online converter to get the answer but it's 52,910.94 ounces. 

We can use unitary method here.

First let us use the basic conversion from tons to ounces.

1 ton =32000 ounces

Now we have to find how many ounces are there in 1.5 tons.

Weight of hippopotamus in tons =1.5 tons

Weight of hippopotamus in ounces = 1.5 *32000 = 48000 ounces.

So the weight of hippopotamus in ounces is 48000 ounces.

The area of a quarter circle is 0.785 square kilometers. What is the quarter circle's perimeter?

Answers

The quarter circle's perimeter is 3.57 when the area of a quarter circle is 0.785 square kilometers.

Area of quarter circle is 0.785

This is a given value in the question.

Hence radius is 1 using the formula (pi*r*r)/4. This is derived after working out this formula.

Since radius is 1, perimeter is 3.57 using the formula (2*pi*r)/(4 + 2*r). This is also derived after working out this formula.

Hence this is the answer for the perimeter of the quarter circle since the given area of the quarter circle tends to be 0.785 square kilometers.

To learn more about area of the circle,

https://brainly.com/question/28642423

Final answer:

The perimeter of a quarter circle with an area of 0.785 km² is 1.57 kilometers.

Explanation:

Let's call the radius of the circle "r".

Since the area of a quarter circle is a quarter of the whole circle's area, we can set up the following equation:

0.785=(1/4)πr^2

To solve for the radius (r), we can:

Multiply both sides by 4: 3.14=πr ^2

Divide both sides by π: r^2=1

Take the square root of both sides to find the radius: r=1 kilometer

Now that we know the radius, we can find the perimeter of the quarter circle.

The perimeter of a whole circle is 2πr, so the perimeter of a quarter circle is:

Perimeter=(1/4)×2πr=(πr)/2

Plugging in the value of r (1 kilometer):

Perimeter=(π×1)/2=  0.5π kilometers = 1.57 kilometers
