A survey of 3 different groups of students was conducted asking students how many texts they sent that day at lunch. The results are summarized below.

Part A:

Group A has a median of?

Which is?
( greater, less, or the same as)

Group B and?
( greater, less, or the same as Group C)

Answer:

A

Step-by-step explanation:

1/1-2/5

Answer:

x= -57

Step-by-step explanation:

7x-63+8x-6

-x-63-7

-x=57

x=-57

Answer:

x = -57

Step-by-step explanation:

Simplify both sides of the equation:

Distribute:

(7)(x) + (7)(-9) = 8x + -6

7x + -63 = 8x -6

7x - 63 = 8x - 6

Subtract 8x from both sides

7x−63−8x=8x−6−8x

−x − 63 = −6

Add 63 to both sides

−x − 63 + 63 = −6 + 63

-x = 57

Divide both sides by -1

-x / -1 = 57 / -1

Therefore, you get x = -57

The solutions to the quadratic equation are x= 0.22 and x= -0.22.

The given quadratic formula is 2x²-5x+1=0.

The roots of a quadratic equation ax² + bx + c = 0 are given by x = [-b ± √(b² - 4ac)]/2a.

Here, x= [5± √(25 - 4×2×1)]/2×2

x= [5± √(25 - 8)]/4

x= (5± √17)/4

x= (5± 4.12)/4

x= 0.88/4 and x= -0.88/4

x= 0.22 and x= -0.22

Therefore, the solutions to the quadratic equation are x= 0.22 and x= -0.22.

Step-by-step explanation:

8-2x1 = 6

Option B number line shows the solution set for |8 - 2p| = 6

A number line is a pictorial representation of numbers on a straight line. It can be used to represent any real number that includes every whole number and natural number. Arithmetic operations of numbers can be better explained on a number line.

According to the question the given expression is  |8 - 2p| = 6

Here the value of "p" is unknown. We have to assume a number and equate it to 6.

Let "p" be ±2, On applying ±2 in the set  |8 - 2(±2)| =0

so not ±2

Now assume ±1, On applying ±1 in the set  |8 - 2(±1)| =6

Value ±1 is shown in the 2nd number line.

Thus the correct option is B

Answer:

5 units.

Step-by-step explanation:

For this problem, you will need to use the distance formula. The distance formula is as shown:

d= [tex]\sqrt{({x_{2}-x_{1})^{2}+({y_{2}-y_{1})^{2} }[/tex]

We can plug in the points which would result in:

d=  [tex]\sqrt{({-4-0)^{2}+(-3-0)^{2} }[/tex]

When solved:

d= [tex]\sqrt{25}[/tex]

Answer:

D

Step-by-step explanation:

The slope is the change in y-coordinates divided by the change in x-coordinates.

Here, the y-coordinates are -4 and -1, and the x-coordinates are -3 and 0, so:

slope = m = (-4 - (-1)) / (-3 - 0) = -3 / -3 = 1

The slope is thus 1, so the answer is D.

We can use the points (-3, -4) and (0, -1) to solve.

Slope formula: y2-y1/x2-x1

= -1-(-4)/0-(-3)

= 3/3

= 1 (Option D)

Best of Luck!

Answer:

-6 is the slope

Step-by-step explanation:

y = −6x + 5

This is of the form

y = mx+b where m is the slope and b is the y intercept

-6 is the slope and 5 is the y intercept

Answer:

( OPINION ) I say this because we are comparing the apples in the fridge(10) to the apples on the table(7).

I hope this was helpful :3

STAY SAFE!! :)

The ratio of apples in the fridge to apples on the table is 10:7. This is calculated by dividing the number of apples in the fridge by the number on the table.

The question asks for the ratio of apples in the fridge to the apples on the table. In order to solve this, you need to understand what a ratio is. A ratio is a way of comparing quantities. Here, the quantity being compared is apples: those in the fridge versus those on the table.

To calculate the ratio, you simply divide the first quantity by the second quantity. So in this case, you have 10 apples in the fridge and 7 apples on the table.

The ratio is therefore 10/7. This can also be written as 10:7.

Final answer:

The distance between the points (-5,3) and (1,-1) is found using the distance formula and is approximately 7.2 units when rounded to the nearest tenth.

Explanation:

To find the distance between two points (-5,3) and (1,-1), we can use the distance formula: √((x2 - x1)² + (y2 - y1)²). Plugging in our values, we get the distance as √((1 - (-5))² + (-1 - 3)²) = √(6² + (-4)²) = √(36 + 16) = √52. To round to the nearest tenth, we calculate √52 and find it is approximately 7.2. Therefore, the distance between the points, rounded to the nearest tenth, is 7.2 units.

Answer:

interval level of measurement

Step-by-step explanation:

Interval level of measurement is numeric and allows for mathematical operations like mean. It is quantitative and in fixed units, i.e changes in values are as a result of a phenomenon. It does not have a zero point i.e a value of zero does not mean what you are measuring is absent, for example a temperature of 0°C do not mean there is no heat applied. It specifies the distance between intervals.

Step-by-step explanation:

Here in this problem ladder forms a right triangle with the wall of the house and it is acts as hypotenuse, length of one leg of right triangle given to be 4 feet.

Let the ladder reaches x ft height of the house.

Hence, by Pythagoras theorem:

[tex] {12}^{2} = {4}^{2} + {x}^{2} \\ 144 = 16 + {x}^{2} \\ {x}^{2} = 144 - 16 \\ {x}^{2} = 128 \\ x = \sqrt{128} \\ x = 11.3137085 \\ x = 11.31 \: ft[/tex]

Hence, the ladder reaches 11.31 ft height of the house.

Final answer:

The function y = 2x is linear and without a period, whereas the function y = sin x is periodic with a period of 2π radians.

Explanation:

The period of a function is the length of the interval over which it repeats.

The function y = 2x is a linear function, not a periodic function, and thus does not have a period.

In contrast, the function y = sin x is a periodic function and has a period of 2π radians.

This means that the sine function repeats its values every 2π radians.

Therefore, when comparing the period of these two functions, we can conclude that y = 2x does not have a defined period, while y = sin x has a period of 2π radians.

Step-by-step explanation:

If I were a college professor taking a survey of how many hours of homework students were assigned and I wanted to organize the data by hour ranges, the visual tool that I would use is C) a frequency table.

A frequency table would be the best visual tool to organize students in hour ranges for a survey of how many hours of homework students were assigned.

A frequency table is a way to organize data into different intervals, or ranges, and count how many data points fall into each interval. In this case, I would create intervals such as 0-1 hour, 1-2 hours, 2-3 hours, and so on, and then count the number of students assigned homework in each interval. This would give me a clear picture of the distribution of homework hours among the students. Therefore the correct answer is C) a frequency table.
