Todd and Joan each generate a random sample of the 250 students in Grade 7 at their school. Each sample has 20 students. Todd and Joan write the numbers 1 through 250 on small pieces of paper and put them in different jars.​ Then, they draw numbers randomly. Describe two things you notice about the two random samples taken from the same population.

Answer:

Parallel = lines with the same slope

Perpendicular = lines whose slopes are negative reciprocals (i.e. product is –1)

Step-by-step explanation:

The first part: circle b, c, d, f (1 ³/₄ is another way of saying ⁷/₄), and h (a horizontal line y = b has a slope of 0)

The second part: circle a, d (1 ⁴/₇ is another way of writing ¹¹/₇, the negative reciprocal of –⁷/₁₁), and e

Answer:

(a) Each triangular part and each rectangular part represents 1/2 the area of one square.

Step-by-step explanation:

Given

See attachment

Required

Which statement is true

Before the division, the area of both squares is:

[tex]Area = l * w[/tex]

After the division:

The area of the triangle is:

[tex]Area = \frac{1}{2} * base * height[/tex]

[tex]A_1 = \frac{1}{2} * l * w[/tex]

Substitute Area for l * w

[tex]A_1 = \frac{1}{2} *Area[/tex]

This equals half the area of the square

The area of the rectangle is:

[tex]Area = length * width[/tex]

The length of the rectangle is now half the length of the original square.

So, we have:

[tex]A_2 = \frac{1}{2} l * w[/tex]

Substitute Area for l * w

[tex]A_2 = \frac{1}{2} *Area[/tex]

From the values of A1 and A2, we can conclude that (a) is true

It states reflected over the y-axis, so treat the y axis as a mirror and you will realise that the x is always the inverse number. For example, if it is -2, the reflected value will be 2. (y remains unchanged)

Answer: the slope is 3/4.

y=mx+b and m is always the slope.

Answer:

the slope is 3/4

Step-by-step explanation:

y = mx + b

y = slopex + y intercept

y = 3/4x - 1

slope = 3/4

y intercept = -1

Answer:

to this question is it is 1.01

Answer:

the square root is 2.82

Step-by-step explanation:

24-16=8

√8=2.82

Answer:

See answers below

Step-by-step explanation:

Using the coordinates from the table (0, 12) and (1, 14)

m = 14-12/1-0

m = 2/0

m = 2

Hence the slope of the table is 2

y intercept occurs at x = 0

Substitute m = 2 and (0,12) into the equation y = mx+c

12 = 2(0) + b

12 = b

b = 12

Hence the y-intercept is 12

Get the equation

Recall that y = mx+c

y = 2x + 12

Hence the required equation is y = 2x+12

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 1) = 2. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 1 = 2. In the next intermediate step the fraction result cannot be further simplified by canceling.

In words - nine halfs plus twelve = thirty-three halfs.

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 7) = 14. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 7 = 14. In the next intermediate step the fraction result cannot be further simplified by canceling.

In words - thirty-three half's plus five sevenths = two hundred forty-one fourteenths.

Step-by-step explanation:

The sum of 4[tex]\frac{1}{2}[/tex] and 8[tex]\frac{3}{14}[/tex] is 12[tex]\frac{5}{7}[/tex].

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Let the required number be n.

According to the question,

the sum of 4[tex]\frac{1}{2}[/tex] and n is equal to 12[tex]\frac{5}{7}[/tex].

In numeric form,

4[tex]\frac{1}{2}[/tex] + n = 12[tex]\frac{5}{7}[/tex]

Simplifying,

9/2 + n = 89/7

Substituting constant to term one side,

n = 89/7 - 9/2

n = 115/14

n = 8[tex]\frac{3}{14}[/tex]

Therefore, the number is 8[tex]\frac{3}{14}[/tex].

Answer:

(4,-4)

x=4

y= -4

Step-by-step explanation:

We know that y is equal to and so we can plug the y value in for x into the other equation

-2x+5(-x)= -28

Solve for x

-2x-5x= -28

-7x= -28

x=4

Now that we know that x= -4 we can plug this into one of the two starting equations and solve for y

y= -(4)

y= -4

Step-by-step explanation:

To be an arithmetic sequence, the numbers have to be added or subtracted by a constant number. D is not the answer because -2+6 equals 4, but 4+6 doesn't equal -6, so D cannot be a arithmetic sequence.

Answer:

$115.20

Step-by-step explanation:

Hi! We need to find 1% of 96 to multiply by 20.

96 / 100 = .96

Now we multiply by 20.

20 x .96 = 19.2.

Now, we add 19.2 to what she earned in the first place (96).

19.2 + 96 = 115.20
