Answer:

first line: 0, 4

explanation: middle of -12 and 12 is 0, then 12/3 = 4

second line: -9, 6

explanation: split into 4 sections per each 12 so 12/4 is 3 and the location of the first unknown point is one section away from 12 so we know the distance between there is 3, leaving -12+3 = -9. Then two sections less than 12 is 12-6 = 6

third line: -12, 4

explanation: 24/6 = 4, -24 + 12 = -12 so 4 units each sections 0 + 4 = 4

1) 4x - 24 = 1000

Add 24 to both sides.

4x = 1024

Divide both sides by 4.

x = 256

The rate that is equivalent to the rate Paula walked is 1/20 mile/minute OR 0.05 mile/minute

From the question, we are to determine the rate which is equivalent to the rate Paula walked

Using the formula,

[tex]Rate = \frac{Distance}{Time}[/tex]

From the given information,

Distance = 1/12 mile

Time = 5/3 minutes

Putting the parameters into the formula, we get

[tex]Rate =\frac{\frac{1}{12} }{\frac{5}{3} }[/tex]

[tex]Rate = \frac{1}{12} \div \frac{5}{3}[/tex]

[tex]Rate = \frac{1}{12} \times \frac{3}{5}[/tex]

[tex]Rate = \frac{3}{60}[/tex]

[tex]Rate = \frac{1}{20}[/tex] mile/minute

Hence, the rate that is equivalent to the rate Paula walked is 1/20 mile/minute OR 0.05 mile/minute

From simplification of the given algebra, the correct answers are as shown below.

1) (a² - b)/(a³b²)

This reduces to;

(a²/(a³b²)) - b/(a³b²)

⇒ a/(ab²) - 1/(a³b)

2) The algebraic expression is;

(b - a)/a³b³

⇒ b/a³b³ - a/a³b³

⇒ 1/a³b² - 1/a²b³

3) The algebraic expression is;

(2 - ab²)/(a²b³)

⇒ (2/(a²b³)) - (ab²)/(a²b³)

⇒ 2/(a²b³)) - 1/(ab)

The 95% confidence interval for the true proportion of first-year students who intend on majoring in liberal arts is option B. 0.62 plus-or-minus 1.96 start root start fraction 0.62 (1 minus 0.62) over 100 end fraction end root .

Confidence interval in statistics is defined as the certain range of values that you estimate for the unknown parameter lies within.

Confidence interval for the population proportion can be calculated as,

p ± z × [tex]\sqrt{\frac{p(1-p)}{n} }[/tex]

Here, p is the sample proportion and n is the sample size.

z value for 95% confidence interval is 1.96.

Here, n = 100,

p = [tex]\frac{62}{100}[/tex] = 0.62

Substituting the values, confidence interval of true proportion is,

0.62 ± 1.96 × [tex]\sqrt{\frac{0.62(1-0.62)}{100} }[/tex]

Hence the 95% confidence interval for the true proportion of first-year students who intend on majoring in liberal arts is 0.62 ± 1.96 × [tex]\sqrt{\frac{0.62(1-0.62)}{100} }[/tex].

The required length ribbon needed to go around the package is 2(3x^2 + 2x -10) / (x^2 + x - 3).

Given that,
Package that had a length of 2x^2+3x-5/x^2+x-3 centimeters and width x^2-x-5/x^2+x-3.

How much ribbon would be needed to go around the package in centimeters is to be determined.

Perimeter is the measure of the figure on its circumference.

The rectangle is a four-sided polygon whose opposites sides are equal and has an angle of 90° between its sides.

Quantity of ribbon = perimeter of the rectangular package
                            = 2 * length + 2* width
                            = 2 * (2x^2+3x-5/x^2+x-3) + 2(x^2-x-5/x^2+x-3)
                            = 2 (3x^2 + 2x -10) / (x^2 + x - 3)

Thus, the required length of  ribbon needed to go around the package is 2(3x^2 + 2x -10) / (x^2 + x - 3).

Answer:

45

Step-by-step explanation:

perimeter is the sum of all sides

for rectangle, it's (length + width) x 2

so do the reverse: 146/ 2 = l + w

73-45 = 30 this means the longer side is 45

=> length is 45

Answer:

C

Step-by-step explanation:

since ∠ m ≅ ∠ p , then

9x - 2 = 4x + 18 ( subtract 4x from both sides )

5x - 2 = 18 ( add 2 to both sides )

5x = 20 ( divide both sides by 5 )

x = 4

then

∠ p = 4x + 8 = 4(4) + 18 = 16 + 18 = 34°

Step-by-step explanation:

1. Separate in two cases:

(a) -2x + 7 = 25          and          (b) -2x + 7 = -25

(a) -2x + 7 = 25  ⇒ subtract 7 from both sides

     -2x = 18 ⇒ divide both sides by -2

      x = -9

(b) -2x + 7 = -25 ⇒ subtract 7 to both sides

    -2x = -32 ⇒ divide both sides by -2

     x = 16
