Suppose there is a strong positive correlation between m and n. Which of the
following must be true?

Answer:

10 rows with the set of 100 blocks is what she will make

Step-by-step explanation:

Where

First row is 1

Second row is 3

Third row is 5

This shows that the blocks are set in an oddly fashion

Meaning each row has a odd number of blocks

Therefore from

1 block- row 1

3 blocks- row2

5 blocks- row 3

7 blocks - row 4

9 blocks- row 5

11 blocks - row 6

13 blocks- row 7

15 blocks - row 8

17 blocks- row 9

19 blocks - row 10

Add of the blocks it amounts to 100 blocks

Meaning the triangular will be at the 10th row when she has use 100 blocks

Answer:

Step-by-step explanation:

The absolute change is the difference between the earnings numbers:

  $15,556,113 -8,556,965 = $6,999,148

__

The relative change is the ratio of this difference to the original amount:

  $6,999,148/$8,556,965 × 100% ≈ 81.794748% ≈ 81.79%

The absolute change in opening weekend earnings from the original Footloose to its remake is $6,999,148, and the relative change is approximately 81.74%.

To calculate the absolute change in opening weekend earnings from the original Footloose movie to its 2011 remake, we subtract the earnings of the original movie from the earnings of the remake. Thus, the absolute change is $15,556,113 - $8,556,965 = $6,999,148.

To find the relative change, we divide the absolute change by the original amount and then multiply by 100 to get a percentage. This gives us ($6,999,148 / $8,556,965) * 100 ≈ 81.74%. Hence, the relative change is approximately 81.74%.

The absolute change represents the direct increase in dollar amount, while the relative change gives us the percentage increase from the original to the remake's opening weekend earnings, providing insight into the growth rate.

Answer: four-fifteenths or [tex]\frac{4}{15}[/tex]

Step-by-step explanation:

What is written with words is mathematically expressed as:

[tex]\frac{9}{15}-\frac{2}{6}[/tex]

We can simplify both fractions, by dividing the numerator and denominator of the first by 3 and dividing the numerator and denominator of the second by 2:

[tex]\frac{9}{15}=\frac{3}{5}[/tex]

[tex]\frac{2}{6}=\frac{1}{3}[/tex]

Then:

[tex]\frac{3}{5}-\frac{1}{3}[/tex]

Calculating the least common multiple (l.c.m) in the denominator as [tex]15[/tex]:

[tex]\frac{9-5}{15}=\frac{4}{15}[/tex] This is the result: four-fifteenths

Answer:

4x² - 20x + 16

Step-by-step explanation:

Given

(4x - 4)(x - 4)

Each term in the second factor is multiplied by each term in the first factor, that is

4x(x - 4) - 4(x - 4) ← distribute both parenthesis

= 4x² - 16x - 4x + 16 ← collect like terms

= 4x² - 20x + 16

Answer:

Step-by-step explanation:

function 1 : y = 4x + 5

In y = mx + b form, which is what ur equation is in, the slope can be found in the m position. So the slope of this function is 4.

function 2 : (1,6),(3,10)

slope = (y2 - y1) / (x2 - x1)

(1,6)...x1 = 1 and y1 = 6

(3,10)...x2 = 3 and y2 = 10

now we sub

slope = (10 - 6) / (3 - 1) = 4/2 = 2

B. Function 1, because the slope is 4 and the slope of function 2 is 2. <==

Answer:

Function 1, because the slope is 4 and the slope of function 2 is 2. Use the slope formula.

Answer:

Unit rate of people per book = 2.5

Step by step explanation:

Given:

Number of peoples =  [tex]10[/tex]

Number of books = [tex]4[/tex]

Their ratios = [tex]10 : 4[/tex]

We have to find the unit rate of people per book.

To find out the unit rate of people per book we have to divide the total number of peoples by the total number of books.

Or

For this we will follow the unitary method:

For [tex]4[/tex] book there are [tex]10[/tex] persons.

For [tex]1[/tex] book there will be [tex]\frac{10}{4}[/tex] persons.

So,

The numeric value = [tex]\frac{10}{4}[/tex]

                               = [tex]2.5[/tex]

There are 2.5 people per book and that it also the unit rate of people per book.

Step-by-step explanation:

Answer:

92.11 cm³

Step-by-step explanation:

The figure below;

We are required to determine the volume of the figure;

The volume of a hemisphere is given by;

Volume hemisphere = 2/3πr³

Taking π to be 3.14

The Volume  of the two hemisphere;

             = 2/3 × 3.14 × 2³

             = 16.75 cm³

Volume of the cylinder;

Volume = πr²h

             = 3.14 × 2² × 6

             = 75.36 cm³

Thus, volume of the figure;

      = 16.75 cm³ + 75.36 cm³

      = 92.11 cm³

Hence, the volume of the figure is 92.11 cm³

[tex]y=-2x-8[/tex]

Step-by-step explanation:

Let [tex]y=mx+c[/tex] be the equation of this line.

The points must satisfy this equation.

When x=-8, and y=8, we get:

[tex]8=-8m+c....(1)[/tex]

When x=1, and y=-10, we get:

[tex]-10=m+c...(2)[/tex]

Subtract equation (1) from equation (2) to get:

[tex]m--8m=-10-8[/tex]

9m=-18

m=-2

We put m=-2 in equation to get (2)

-10=-2+c

c=-10+2

c=-8

Therefore the equation is:

y=-2x-8

Answer:

(p - 12)(p + 2)  or

p^2 - 10p - 24.

Step-by-step explanation:

We use the Difference of 2 Squares Identity.

a^2 - b^2 = (a - b)(a + b).

So (p - 5)^2 - 49

= (p - 5 - 7)(p - 5 + 7)

= (p - 12)(p + 2)

= p^2 - 10p - 24.

Answer:

(p - 12)(p + 2)

Step-by-step explanation:

(p-5)² - 49​ =

= (p - 5 - 7)(p - 5 + 7)

= (p - 12)(p + 2)

a² - b² = (a - b)(a + b)

a = p - 5

b = 49

Rachel bought six 20-cent stamps and eight 30-cent stamps.

Step-by-step explanation:

Given,

Amount spent on stamps = $3.60 = 3.60*100 = 360 cents

Let,

x = 20 cent stamps

y = 30 cent stamps

According to given statement;

20x+30y=360      Eqn 1

x = y-2                  Eqn 2

Putting value of x from Eqn 2 in Eqn 1

[tex]20(y-2)+30y=360\\20y-40+30y=360\\50y=360+40\\50y=400[/tex]

Dividing both sides by 50

[tex]\frac{50y}{50}=\frac{400}{50}\\y=8[/tex]

Putting y=8 in Eqn 2

[tex]x=8-2\\x=6[/tex]

Rachel bought six 20-cent stamps and eight 30-cent stamps.

Final answer:

Rachel bought 8 thirty-cent stamps and 6 twenty-cent stamps. We solved a system of equations representing the cost of the stamps and their quantity relationship to determine the numbers.

Explanation:

Rachel spent $3.60 for stamps to mail packages, buying 30-cent stamps and 20-cent stamps. The number of 20-cent stamps was 2 less than the number of 30-cent stamps. To solve this, we can use a system of equations to represent the total cost and the relationship between the number of stamps:

Let x be the number of 30-cent stamps.

Let y be the number of 20-cent stamps.

Based on the information given:

0.30x + 0.20y = 3.60 (Total cost equation)

y = x - 2 (Relationship between the stamps)

We substitute the second equation into the first equation:

0.30x + 0.20(x - 2) = 3.60

0.30x + 0.20x - 0.40 = 3.60

0.50x = 4.00

x = 8

Now we solve for y using the second equation:

y = 8 - 2

y = 6

So Rachel bought 8 thirty-cent stamps and 6 twenty-cent stamps.

The annual percentage rate is: 1.2%

Step-by-step explanation:

The formula for calculating simple interest is:

[tex]I = Prt[/tex]

Here

P is the principal amount

r is the interest rate

t is the time in years

We are Given:

[tex]P = 1450\\t = 8\ years\\I = 139.20[/tex]

Putting the values in the formula

[tex]139.20 = 1450 * r * 8\\139.20 = 11600r[/tex]

Dividing both sides by 11600

[tex]\frac{11600r}{11600} = \frac{139.20}{11600}\\r = 0.012[/tex]

Converting into percentage

r  = 0.012*100

r = 1.2%

Step-by-step explanation:

p² + (p+7)² = 169

p² + (p²+14p+49) = 169

2p² + 14p + 49 - 169 = 0

2p² + 14p - 120 = 0

2p² + 24p - 10p - 120 = 0

2p(p+12) - 10(p+12) = 0

(p+12)(2p-10) = 0

p+12 = 0 , or 2p-10 = 0

p = -12 or 5

Answer:

p = 3

Step-by-step explanation:

p² + (p +7)²=169

Open the bracket and solve the value in the bracket according to BODMAS

p^2 + p^2 + 7^2 = 13^2

Square Root the both side of the equation.

p + p +7 = 13

2p + 7 = 13

collect like term of the numbers

2p = 13 - 7

2p = 6

Divide both side by the coefficient of p.

2p/2 = 6/2

p = 3.
