Rewrite the following equation in logarithmic form:
16 = 8^4/3

Answer:

Any number above 85.6

Step-by-step explanation:

To calculate the mean you add all of the scores together then divide by how many scores you added

So in this case you would add 84 + 72 + 90 + 87 + 95 = 428

Then you would Divide 428 by five because you are adding 5 numbers

428/5 = 85.6

It says the score increased so as long as then score is greater than 85.6 it is an option.

Answer:

90, 86, 89, and 92

Step-by-step explanation:

Basically anything above 85.6

The equation of the parabola opening up or down with a vertex at the origin and passing through the point (4,2) is y = 0.125x².

The equation of a parabola in vertex form is represented by y = a(x-h)² + k, where (h, k) is the vertex of the parabola, and 'a' is a coefficient that determines the direction and steepness of the parabola.

Since the vertex of the parabola in this case is at the origin (0, 0), the equation simplifies to y = ax²

We know the curve passes through the point (4,2), so we can substitute these values into the equation 2 = a(4)², which simplifies to 2 = 16a. Solving for 'a' gives us a = 2/16 or a = 0.125.

Thus, the equation of the parabola is y = 0.125x²

The equation of a parabola with vertex at (0,0) passing through (4,2) is y = (1/8)x². This is derived by using the vertex form and solving for 'a'.

Equation of a Parabola in Vertex Form

The equation of a parabola in vertex form is given by:

y = a(x - h)² + k, where (h, k) is the vertex.

In this case, the vertex of the parabola is at (0, 0), so the equation simplifies to:

y = ax²

Since the parabola passes through the point (4, 2), we can substitute this point into the equation to find the value of 'a':

Substitute x = 4 and y = 2:

2 = a(4)²

2 = 16a

Solve for 'a': a = 2/16 = 1/8

Therefore, the equation of the parabola in vertex form is: y = (1/8)x²

Answer:

¢42 per game

¢1.11 per minute

Step-by-step explanation:

Please refer to the attached image for explanations

LeBron James earns approximately $0.42 per game and $0.01 per minute based on the given salary and total games and minutes played for the season.

The student has asked two questions about calculating earnings per game and per minute for LeBron James, based on a given salary for a season and the total number of games and minutes played.

To calculate the earnings per game, we divide the total salary for the season by the number of games played. If LeBron James was paid $31 for the season and played 74 games, his earnings per game would be: $31 ÷ 74 games = $0.4189 per game, which rounds to $0.42 per game to the nearest cent.

For the earnings per minute, we divide the total salary for the season by the total number of minutes played. With $31 for the season and 2,796 minutes played, his pay per minute would be: $31 ÷ 2,796 minutes = $0.0111 per minute, rounding to $0.01 per minute to the nearest cent.

Answer:

33 Points

Step-by-step explanation:

We can figure out that the total number of points scored by the team is 38+45+49=132. Since we know that Caitlin scored 1/4 of these total points, and 1/4 of 132=33, then she scored 33 points during the first three games.

Answer:

It is not reasonable

Step-by-step explanation:

We have a population of 150 and the person takes 10 data from the raccoons, if we take the average of these values, we are left with:

(17 +19 +20 +21 +23 +27 +28 +28+ 28 + 32) / 10 = 24.3

Therefore the inference of the average weight is to approximate up to 25.

This is NOT correct, since it cannot be approximated in this way first and also that the sample is not representative. 10 sample data of 150, which is the population, will give results with a very large margin of error and with a minimum level of confidence.

Therefore it is not reasonable.

Answer:

No

Step-by-step explanation:

Here we have the weights as follows

17, 19, 20, 21, 23, 27, 28, 28, 28, 32

Sum = 243 pounds

Sample size = 10

Which gives the average as 243/10 = 24.3

Therefore, since the average is a point estimate, and measure of central tendency, to give the average rounded up in error will impact on the description of the data as the average is closer to 24 than to 25.

Step-by-step explanation:

Joseph and Wilson will each have ridden 45 kilometers to meet halfway, and it will take each of them 5 hours to do so.

Joseph and Wilson are biking towards each other. Joseph has already traveled 10 kilometers and is moving at a constant speed of 7 kilometers per hour. Wilson has just started and rides at a speed of 9 kilometers per hour. To determine how far each boy will have ridden to meet halfway and how long that will take, we need to use the relation between distance, speed, and time.

Let's assume the total distance between their houses is 2d kilometers. Meeting halfway means each boy will cover d kilometers. We already know Joseph has covered 10 kilometers, so he has d - 10 kilometers left to travel. Since Wilson just started, he has the entire d kilometers to cover.

The time it will take for each to travel the remaining distance can be calculated using the formula:

Time = Distance ÷ Speed

For Joseph:
Time = [tex]\frac{d - 10}{ 7}[/tex]

For Wilson:
Time = [tex]\frac{d }{ 9}[/tex]

Since they meet halfway at the same time, the times for each to travel the remaining distance must be equal.
[tex]\frac{d - 10}{ 7} = \frac{d }{ 9}[/tex]

By solving this equation cross-multiplying, we get:
9(d - 10) = 7d

9d - 90 = 7d

2d = 90

d = 45

Each boy will ride for 45 kilometers to meet halfway. Joseph has already covered 10 kilometers, so he will ride an additional 35 kilometers (45 km - 10 km).

Now to find out how long it will take:

For Joseph:
Time = 35 ÷ 7 hours = 5 hours

For Wilson:
Time = 45 ÷ 9 hours = 5 hours

So, both boys will have ridden for 5 hours to meet each other halfway.

To find the area of the shaded region, subtract the area of the smaller circle from the area of the larger circle.

To find the area of the shaded region, we need to subtract the area of the smaller circle from the area of the larger circle.

The formula to find the area of a circle is pi * r^2, where pi is approximately 3.14 and r is the radius of the circle.

Let's assume the radius of the larger circle is 4 units and the radius of the smaller circle is 3 units. The area of the larger circle is 3.14 * 4^2 = 50.24 square units, and the area of the smaller circle is 3.14 * 3^2 = 28.26 square units.

Therefore, the area of the shaded region is 50.24 - 28.26 = 21.98 square units.

Answer:

It is A

Step-by-step explanation:

Answer:

Step-by-step explanation:

The given quadratic equation is expressed as

4x² + 2x = 7

The first step is to divide both sides of the equation by 4. It becomes

4x²/4 + 2x/4 = 7/4

x² + x/2 = 7/4

The next step is to add the square of half of the coefficient of x to both sides of the equation. It becomes

x² + x/2 + (1/4)² = 7/4 + (1/4)²

(x + 1/4)² = 7/4 + 1/16

(x + 1/4)² = 29/16

Taking square root of both sides of the equation, it becomes

x + 1/4 = ±√29/4

x = - 1/4 ± √29/4

x = (- 1 + √29)/4 or x = (- 1 - √29)/4

x = (- 1 + 5.385)/4 or x = (- 1 - 5.385)/4

x = 1.09625 or x = - 1.59625

0.694 rounded to the nearest hundredth remains 0.69 because the third digit after the decimal is 4, which is less than 5.

The question asks for 0.694 to be rounded to the nearest hundredth.

To round to the nearest hundredth, you look at the third digit after the decimal point.

If this digit is 5 or greater, you round the second digit after the decimal up.

In this case, the third digit is 4, which is less than 5.

Therefore, when rounding 0.694 to the nearest hundredth, it remains 0.69.

Answer:

7 cans

Step-by-step explanation:

-The number of cans that can be fitted is obtained by dividing the volume of the shelf by the volume of an individual can.

-Volume of the shelf is calculated as below:

[tex]V_{shelf}=lwh\\\\=10\times10\times4\\\\=400\ in^3[/tex]

#We then divide by the volume of a can:

[tex]No \ of \ cans=\frac{V_{shelf}}{V_{can}}\\\\=\frac{400}{50.24}\\\\=7.96\approx 7\ cans[/tex]

We round down since the 8th can cannot properly fit.

Hence, only 7 cans will fit in the shelf

A shelf that is 10 inches tall and 10 inches wide can fit up to 4 cans of vegetables.

To determine how many cans of vegetables fit on Sam's shelf, we need to compare the dimensions of the shelf with the dimensions of the cans. Given:

We assume we stack the cans upright, which is the most common arrangement in a shelf. Each can occupies a 4-inch height. Therefore, we can stack:

10 inches / 4 inches = 2.5 cans

Since we cannot have half a can, we round down to 2 cans high. The shelf width allows for:

10 inches / 4 inches = 2.5 cans wide

Again, rounding down, 2 cans wide. Since we only have shelf dimensions in height and width (depth isn't mentioned, we'll assume a single layer in depth), the total number of cans that fit is:

2 (height) x 2 (width) = 4 cans
