I believe your answer is:

Here’s why:  

⸻⸻⸻⸻

[tex]2k+9=7-3k\\\rule{150}{0.5}\\\rightarrow 2k + 9 = 7-3k\\\\\rightarrow 2k + 3k + 9 = 7 - 3k + 3k\\\\\rightarrow 5k + 9 = 7\\\\\rightarrow5k + 9 - 9 = 7 - 9\\\\\rightarrow 5k = -2\\\\\rightarrow \frac{5k=-2}{5}\\\\\rightarrow \boxed{k = -\frac{2}{5} = -0.4}[/tex]

Answer:

3/10

Step-by-step explanation:

Answer: x = 10

Step-by-step explanation:

The formula to find the volume of a cube is as following:

V = x³

Since we already know the volume, let's substitute it in the formula.

1000 = x³

To find x, we should do the cube root on each side.

∛1000 = ∛x³

x = 10

Step-by-step explanation:

Answer:

[tex]x + 7 < 10 \\ x < 10 - 7 \\ x < 3[/tex]

Testing the hypothesis, it is found that the correct option is:

b. Not significantly greater than 55%.

At the null hypothesis, we test if the proportion is not significantly more than 55%, that is:

[tex]H_0: p \leq 0.55[/tex]

At the alternative hypothesis, we test if the proportion is significantly more than 55%, that is:

[tex]H_1: p < 0.55[/tex]

The test statistic is given by:

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

In which:

For this problem, the parameters are:

[tex]p = 0.55, n = 100, \overline{p} = \frac{60}{100} = 0.6[/tex]

Hence, the value of the test statistic is:

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

[tex]z = \frac{0.6 - 0.55}{\sqrt{\frac{0.55(0.45)}{100}}}[/tex]

[tex]z = 1.01[/tex]

The p-value of the test is the probability of finding a sample proportion above 0.6, which is 1 subtracted by the p-value of z = 1.01.

Looking at the z-table, z = 1.01 has a p-value of 0.8438.

1 - 0.8438 = 0.1562.

The p-value of the test is 0.1562 > 0.05, which means that the proportion is not significantly greater than 55%, and option b is correct.

Answer:

8% is the sales tax rate

Step-by-step explanation:

I'm not the best with math but the way I found the answer was by first using my local sales tax rate and determining how much the tax would be.

490 * 8.75% = 42.875

Knowing that this amount was higher than in the equation, I lowered the sales tax to 8% (0.08)

490 * 8% = 39.2

Answer:

x < 15

Step-by-step explanation:

[tex]\frac{x}{5}[/tex] - 3 < 0 ( add 3 to both sides )

[tex]\frac{x}{5}[/tex] < 3 ( multiply both sides by 5 to clear the fraction )

x < 15

Answer:

The next three natural numbers after 10999 are 11000,11001, and 11002.

Step-by-step explanation:

Write first natural number after 10999:

10999 + 1 = 11000

Write second natural number after 11000:

11000 + 1 = 11001

Write the third natural number after 11001:

11001 + 1 = 11002

Hence, the next three natural numbers after 10999 are 11000, 11001, and 11002.

Answer: The rate of change of momentum of a body over time is directly proportional to the force applied and occurs in the same direction as the applied force.

We can write the law as:

Where F is a force, and P is the momentum.

Remember that the momentum is defined as the quantity of motion, such that:

P = M*V

Where M is the mass of the moving object and V is the velocity of the moving object.

Or we can write the second law as:

F = M*a

M = mass

a = acceleration

Answer:

The slope in this equation is 2x, so answer is 2.

Step-by-step explanation:

8x-4y-9=0

-8x -8x

-4y-9 = -8x

+9 +9

-4y = -8x+9

Divide by 4 on both side to have y by itself and you get

y = 2x - 9/4

Answer:

Isolate the variable by dividing each side by factors that don't contain the variable.

Inequality Form:

x≥9

Interval Notation:

[9,∞)

Step-by-step explanation:

Answer:

x = 9

Step-by-step explanation:

Step 1: Subtract 4x from both sides.

Step 2: Divide both sides by 3.

Step 3: Check if solution is correct.

Therefore, x = 9.
