Answer:

1) He should have found the average of the number of rock songs by averaging 4 and 6 to get 5.

2) He did not multiply the numerator and denominator by the correct number to equal 1,500.

5) He should have multiplied the numerator and denominator by 75, not 30,  because 20 x 75 = 1,500.

Step-by-step explanation:

Final answer:

Josiah made errors in predicting the number of rock songs on his MP3 player by not averaging the samples correctly and by using the wrong multiplication factor in his proportion calculation. The correct average should be 5, and he should have used a factor of 75 to scale his samples up to the total number of songs.

Explanation:

The student has used a proportion to predict the number of rock songs on his MP3 player based on a sample. However, the prediction method has a few mistakes that should be corrected for an accurate estimate.

Josiah's initial prediction did not consider averaging the number of rock songs from both samples, which would have given a better representation of the average occurrence in the sample set. The correct average is (4+6)/2 = 5 rock songs per sample.

The proportion set up by Josiah is 10/20 = x/1,500, which implies that the 10 rock songs in his samples represent half of all songs played. This should have been compared to the total number of songs on the MP3 player, 1,500, requiring him to multiply by a specific number. Yet, the multiplication factor used (30) was incorrect. To scale up 20 to 1,500, he should use the factor of 75, because 20 × 75 = 1,500.

The correct proportion should be 5/20 = x/1,500, which simplifies to 1/4 = x/1,500, and then x = 1,500/4 = 375. Hence, the predicted number of rock songs based on the sample should be 375.

Answer:

A) Vol_10_cubes  = 2*(5^4) inch^3

B) Area_10_cubes = (2^2)*3*(5^3)  inch^2

Step-by-step explanation:

A)The volume of a cube, as all sides are equal:

Vol_cube = (side)^3

side = 5 inches

Vol_cube  = 5^3 inch^3

Since we have 10 cubes

10 = 2*5

Vol_10_cubes  = 2*(5^4) inch^3

B) A cube has six faces, each with area equal to its squared side

Area_cube = 6*(side)^2

Area_cube = 6*(5)^2  inch^2

Area_10_cubes = 2*5*6*(5)^2  inch^2

Area_10_cubes = (2^2)*3*(5)^3  inch^2

The total volume of Han's cubes is given by the expression 10 × 5³ cubic inches, and the total surface area can be expressed as 10 × 6 × 5² square inches.

The question asks for the calculation of volume and surface area of cubes with a given side length.

Volume Calculation

To find the volume of a single cube, we use the formula V = s³, where s is the length of a side of the cube. Because each side of the cube is 5 inches, the volume of one cube is V = 5³ inches³, which equals 125 cubic inches. Now, Han has 10 cubes, so the total volume is 10 times the volume of one cube, which can be expressed as:

Total Volume = 10 × 5³ inches³

Surface Area Calculation

The surface area of a single cube is found using the formula SA = 6s², since there are six sides to a cube. With a side length of 5 inches, the surface area of one cube is SA = 6 × 5² square inches, which equals 150 square inches. For 10 cubes, the total surface area is 10 times the surface area of one cube, which can be expressed as:

Total Surface Area = 10 × 6 × 5² square inches

step 2

Find the equation of the dashed blue line

Let

[tex]A(0,3),B(3,5)[/tex]

Find the slope

[tex]m=(5-3)/(3-0)=2/3[/tex]

The equation of the line is

The next part is B: -14,3

trust me

The points you need to calculate are the average rate of change from the beginning of the slide (0, 80) and (15, 10).Options A and D are correct.

The length of the line segment connecting two places is the distance between them. The distance between two places is always positive, and equal-length segments are referred to as congruent segments.

The given coordinate in the problem is;

(x₁,y₁)=(0, 80)

(x₂, y₂)=(15, 10)

The distance between the two points on the x-axis is found as;

d = 15 -0 feet

d = 15 feet

The points you need to calculate the average rate of change from the beginning of the slide to when the slide has covered a horizontal distance of 15 feet will be (0, 80) and (15, 10)

Hence, options A and D are correct.

Answer:

parallel

Step-by-step explanation:

Solve both equations for y to make it easier to compare them.

2x - 5y = 0 ↔ 5y = 2x, or y = (5/2)x.

y = (5/2)x - 3

Since the slopes are the same, the two lines are parallel.

Answer:

5

Step-by-step explanation:

We need to use Pythagoras' theorem.

For this we can use the pythagoras formula a^2+b^2=c^2 and rearrange this

We then will have 8^2+b^2=89

(because 89(sqrt) squared is 89)

We can then solve for what x is.

We take away 64 from 89 which is 25

the square root of 25 is 5

Therefore x=5

Answer:

9 bags

Step-by-step explanation:

22 - 13 = 9

Since there is two carts and we know that in one of them (bigger one) is 13 bags and that we know there is in sum of two 22 bags, we will need to subract sum of bags from two carts by bags from bigger cart to get amount of bags in small cart (in which one we finding that there will be 9 bags).

The smaller cart contains 9 bags.

It is given that two carts have 22 bags of groceries between them.

Also given that the larger one has 13 bags in it .

Therefore to find the bags in the smaller cart is =

(22 - 13) = 9 bags.

Therefore the smaller cart contains 9 bags.

The width of the prism is approximately 2.2 feet.

Let's assume that the width of the prism is x feet. Since the length of the prism is four times the width, the length can be represented as 4x feet. Given that the height is 8 feet, we can use the formula for the volume of a rectangular prism: Volume = Length x Width x Height. Plugging in the given values, we get the equation 160 = 4x * x * 8. By solving this equation, we find that the width of the prism is approximately 2.2 feet (when rounded to the nearest tenth).

Segment CR.

Step-by-step explanation:

We know that the altitude of triangle is the perpendicular drawn from a vertex of triangle to opposite side.

We can see that vertex opposite to segment AB is [tex]\angle ACB[/tex]. We can see that there are two lines drawn from vertex C that are segment CR and CN.

We have been given that points L, M and N are midpoints for our given triangle. We know that segment that is midpoint of triangle is known as median of triangle, therefore, CN is not a correct choice.

We can see that segment CR is perpendicular to segment AB, therefore, option B is the correct choice.
