1. -9p - 17 = 10

-9p = 10 + 17

-9p = 27

p = -3

2. w/4 - 4 = 3

w/4 = 3 + 4

w/4 = 7

w = 7 · 4

w = 28

3. x/5 + 6 = 10

x/5 = 10 - 6

x/5 = 4

x = 4 · 5

x = 20

4. -2(m - 30) = -6m

-2m + 60 = -6m

-2m + 6m = -60

4m = -60

m = -15

5. 3.75 + 3.7 = 1.7 + 1.75x

1.75x = 3.75 + 3.7 - 1.7

1.75x = 5.75

x = 23/7

6. -6 - 7(c + 10)

= -6 -7c - 70

= -76 - 7c

7. 2x + 3(x - 2) - 2(x - 6)

= 2x + 3x - 6 - 2x + 12

= 3x + 6

8. c + 6 -3

= c + 3

10. -5p > -30

p < 6

13. 29 - 5x = 4; $5.00

14. 64 + w = 2w + 8; 56 pounds

For Q#5, 7, 8, and 10, I got a different answer from the one you provided. I did it the way I was taught to do it, which might be different from what you were taught. Sorry about that; I tried my best.

A sample proportion of 0.36 is found. To determine the margin of error for this statistic, a simulation of 100 trials is run, ea

Reika [66]

Answer:

(0.30, 0.42)

Step-by-step explanation:

Given the sample proportion is = 0.36

Number of trials required for determining the margin of the error = 100

Sample size, n = 50

The point estimate = 0.36

The minimum sample proportion form the simulation = 0.28

The maximum sample proportion from the simulation = 0.40

Also the margin of the error of population proportion is found by using the half of the range.

Therefore, the interval estimate for the true population proportion is = (0.30, 0.42)

A boat can travel 315 miles on 63 gallons of gasoline. How much gasoline will it need to go 5 miles?

Oksi-84 [34.3K]

$\begin{array}{ccll} miles&\stackrel{gasoline}{gallons}\\ \cline{1-2} 315 & 63\\ 5& x \end{array} \implies \cfrac{315}{5}~~=~~\cfrac{63}{x} \\\\\\ 63=\cfrac{63}{x}\implies 63x=63\implies x=\cfrac{63}{63}\implies x=1$

What is the following sum? 2 (RootIndex 3 StartRoot 16 x cubed y EndRoot) 4 (RootIndex 3 StartRoot 54 x Superscript 6 Baseline y

san4es73 [151]

Equivalent expressions are expressions that have the same value, and can be used interchangeably.

The result of the sum $2 (\sqrt[3]{16x^3y}) + 4 (\sqrt[3]{54x^6y^5})$ is $4x\sqrt[3]{2y} + 8x^2y\sqrt[3]{2y^2})$

The expression is given as:

$2 (\sqrt[3]{16x^3y}) + 4 (\sqrt[3]{54x^6y^5})$

Rewrite the expression as:

$2 (\sqrt[3]{16x^3y}) + 4 (\sqrt[3]{54x^6y^5}) = 2 (\sqrt[3]{2^4x^3y}) + 4 (\sqrt[3]{3^3 \times 2x^6y^5})$

Evaluate the roots

$2 (\sqrt[3]{16x^3y}) + 4 (\sqrt[3]{54x^6y^5}) = 2 (2x\sqrt[3]{2y}) + 4 (3x^2y\sqrt[3]{2y^2})$

Open the brackets

$2 (\sqrt[3]{16x^3y}) + 4 (\sqrt[3]{54x^6y^5}) = 4x\sqrt[3]{2y} + 12x^2y\sqrt[3]{2y^2})$

The above expression cannot be further simplified.

Hence, the result of the sum $2 (\sqrt[3]{16x^3y}) + 4 (\sqrt[3]{54x^6y^5})$ is $4x\sqrt[3]{2y} + 8x^2y\sqrt[3]{2y^2})$
