write (x^2)^4 without exponents

Answers

Answer 1

Answer: x8 i really don't know if it is correct tell me plz

Step-by-step explanation:

Answer 2

The expression (x²)⁴ without exponents can be written as x × x × x × x × x × x × x × x.

The given expression is (x²)⁴.

It is known that the power rule of exponents states that:

(xᵃ)ᵇ = xᵃᵇ

Here, a = 2 and b = 4.

So using the power rule,

(x²)⁴ = x²⁽⁴⁾

= x⁸

Now, it is known that exponents are actually the multiplication of the number with the same number again and again.

Here x is multiplied by itself 8 times.

So the expression can be written as:

x × x × x × x × x × x × x × x.

For each ordered pair,solve the percent problems to find the corridinates (x% of 31 is 3.317,4.407 is 39% of y)

Answers

Answer:

x=10.7, y=11300

Step-by-step explanation:

x%of 31 = 3.317

x/100×31=3.317

31x/100=3.317

31x= 3.317×100

x= 3.317 ×100/31

x =10.7

4407= 39% of y

4407= 39/100 × y

4407 =39y/100

4407×100=39y

4407 × 100/39=y

11300=y

The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.

Mountain View School Seaside School
0 5, 8
9, 8, 2, 0 1 0, 1, 2, 5, 6, 8
8, 7, 6, 5, 5, 4, 4, 3, 1, 0 2 5, 5, 7, 7, 8
0 3 0, 6
Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside

Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice

Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

100 points and brainliest if answered quickly!!!! Nick is investigating cell phone use in his hometown. So far, he has found that the residents used their cell phones for 217,470 minutes last year. This year, they used their cell phones for a total of 434,940 minutes. What is the percent of increase in annual usage?

Answers

To calculate the percent increase in annual usage of cell phones, we can use the following formula:

Percent increase = [(new value - original value) / original value] x 100

where the new value is the current year’s usage and the original value is last year’s usage.

In this case, Nick found that residents used their cell phones for 217,470 minutes last year and 434,940 minutes this year. So we can plug these values into the formula:

Percent increase = [(434940 - 217470) / 217470] x 100

Percent increase = 100%

Therefore, there was a 100% increase in annual usage of cell phones.

I hope that helps! Let me know if you have any other questions.

Answer:

6670 divided by 2=3335 SOOOO the answer is :3335

4) y=5-x

gradient= -1

y-intercept= 5

y-intercept= 8

6) y= 1/4x+3

Tom is saving money to buy a game. So far he has saved $18, which is two-thirds of the total cost of the game. How much does the game cost?

Answers

To determine the total cost of the game, we can set up an equation based on the given information.

Let's assume the total cost of the game is represented by the variable "x."

According to the problem, Tom has saved $18, which is two-thirds of the total cost. We can express this as the equation:

(2/3) * x = $18

To solve for x, we can multiply both sides of the equation by the reciprocal of 2/3, which is 3/2:

(3/2) * (2/3) * x = (3/2) * $18

x = $27

Therefore, the game costs $27.

~~~Harsha~~~

The game costs $27 all you really have to do is 9 times 3
1/3- 9
2/3- 18
3/3- 27

The discriminant is equal to 128, which means the equation has no real number solutions.

The discriminant is equal to 128, which means the equation has two real number solutions.

Answers

Answer:

B: The discriminant is equal to zero which means it has one real number solution

Step-by-step explanation:

Hello Again!!

Your right answer will be is B. The discriminant is equal to 0, which means the equation has one real number solution.

For this case we have the following quadratic equation:

2x^2 - 8x + = 0

Where:

a = 2

B = -8

c = 8

The discriminant is given by:

d = b^2 - 4(a)(c)

Substituting the values we have:

d = (-8)^2 - 4(2)(8)

d = 64 - 64

d = 0

So, Your best answer choice is B.

Good Luck!!

To multiply fractions, multiply across, top and bottom.

$\frac{9}{16 } < \frac{3}{8} \\\\$

Get common denominators to determine. Multiply the second one by 2/2

$\frac{9}{16} < \frac{6}{16}$

The numerator on the second one is smaller, and they have the same same denominators, therefore, this is false.

Firstly, you have to find the area of the whole shape. After that, you subtract that from the area of the individual triangle to get your answer.

The whole shape is a rectangle, with a length of 6 and a width of 7.
To find the area, multiply 6 by 7=42yd^2

The area of the entire shape is 42yd^2

Now, the vertical 4yd side plus the height of the dotted triangle will equal 6yd.
So the height of the dotted triangle is 6-4=2yd.

The horizontal 4yd side plus the base of the dotted triangle will equal 7yd.
So the base of the dotted triangle is 7-4=3yd.

Formula for area of triangle: 1/2 x base x height
1/2 x 4 x 3= 6yd^2

The area of the dotted triangle is 6yd^2

Now subtract the area of the whole shape by the area of the dotted triangle to get the shaded region.

42-6= 36yd^2

Area of shaded region: 36yd^2 (i think)
