Solving the equation 4x + 7 = 9 will give value of x = 1/2

To solve we will use the equation

4x + 7 = 9

By subtracting 7 from both side we get

4x + 7 -7 = 9 -7

4x = 2

By diving 4 from both sides we get

4x/4 = 2/4

x = 1/2

To check we put the value of x in the equation we get

4(1/2) + 7 = 9

2 + 7  = 9

9 = 9

Hence the value of x is satisfying the equation

Therefore, the value of x is 1/2

Answer: This is a binomial distribution problem with parameters n = 17 and p = 0.3, where n is the sample size and p is the probability of a defective bulb. We need to find the probability that between 3 and 6 (both inclusive) bulbs from the sample are defective.

Let X be the number of defective bulbs in the sample. Then X has a binomial distribution with parameters n = 17 and p = 0.3, i.e., X ~ B(17, 0.3).

We want to find P(3 ≤ X ≤ 6). Using the binomial probability formula, we have:

P(3 ≤ X ≤ 6) = P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6)

= (17 choose 3)(0.3^3)(0.7^14) + (17 choose 4)(0.3^4)(0.7^13) + (17 choose 5)(0.3^5)(0.7^12) + (17 choose 6)(0.3^6)(0.7^11)

≈ 0.1566 (rounded to four decimal places)

Therefore, the probability that between 3 and 6 (both inclusive) bulbs from the sample are defective is approximately 0.1566.

Step-by-step explanation:

The calcuated value of the proportionality constant (y to x) is 15

To find the proportionality constant between the distance and time, we can use the formula:

proportionality constant = y/x

where y is the distance and x is the time.

From the graph, we know that when x = 1, y = 15. Therefore, the proportionality constant can be calculated as follows:

proportionality constant = y/x = 15/1 = 15

So, the proportionality constant between the distance and time is 15.

The ratio of the areas of two similar polygons is equal to the square of the ratio of their corresponding side lengths. Since the scale factor of the polygons is 3:8, the ratio of their corresponding side lengths is 3/8. Therefore, the ratio of their areas is (3/8)^2 = 9/64.

The ratio of the areas of two similar circles is equal to the square of the ratio of their radii. Since the scale factor of the circles is 2:3, the ratio of their radii is 2/3. Therefore, the ratio of their areas is (2/3)^2 = 4/9. Since the area of the larger circle is 64π, the area of the smaller circle is (4/9) * 64π = 28.44π.

The ratio of the areas of two similar polygons is equal to the square of the ratio of their corresponding side lengths. Since the ratio of the areas of the two regular pentagons is 150√3/54√3 = 25/9, the ratio of their corresponding side lengths is the square root of the ratio of their areas, which is √(25/9) = 5/3.

Explanation:

The w/4 term is the same as (1/4)w or 0.25w since 1/4 = 0.25

Because a variable is attached to this term, it is not constant. The same can be said about the -7z term as well.

The 12.5 is constant. It never changes. It will always be 12.5 no matter what the other variable terms change to.

For example, if w = 12, then the term w/4 becomes 12/4 = 3. Or if w = 24, then w/4 = 24/4 = 6 is the new value. This shows that term changing depending on the input variable.

Answer:

4096.

Step-by-step explanation:

We need to check if it's a geometric or arithmetic sequence (looking for the common ratio, r). The sequence goes -4, 8, -16, 32, so we can multiply the previous number by -2 to get the next number, and so on and so forth. This makes it a geometric sequence.

The formula for finding the nth term of a geometric sequence is [tex]u_{n} = u_{1} r^{n-1}[/tex]. The term we are looking for is the 11th. Let's plug these values in now:

[tex]u_{n} = u_{1}r^{n-1}[/tex]

[tex]u_{11} = -4(-2)^{11-1}[/tex]

[tex]u_{11} = 4096[/tex]

Therefore the 11th term is 4096.

With a 99% confidence level, we can say that the true proportion of all homes that have electrical/environmental problems is at least 8.3%.

To calculate a lower confidence bound using a confidence level of 99% for the percentage of all homes that have electrical/environmental problems, we need to have a sample of data on this issue. Let's assume that we have a random sample of 100 homes, and 20 of them were found to have electrical/environmental problems.

To calculate the lower confidence bound, we can use the formula:

Lower bound = p - zα/2 * sqrt(p * (1-p) / n)

where:

p = proportion of homes in the sample that have electrical/environmental problems = 20/100 = 0.2

zα/2 = z-score for the given confidence level of 99% = 2.576 (obtained from a standard normal distribution table or calculator)

n = sample size = 100

Plugging in these values, we get:

Lower bound = 0.2 - 2.576 * sqrt(0.2 * 0.8 / 100) = 0.083

Therefore, with a 99% confidence level, we can say that the true proportion of all homes that have electrical/environmental problems is at least 8.3%.

at least 17.5%.

To calculate a lower confidence bound using a confidence level of 99% for the percentage of all homes that have

electrical/environmental problems, you would need a sample of homes and the number of homes in the sample that

have such problems. Using this information, you could calculate the sample proportion (p-hat) of homes with

electrical/environmental problems.

Then, using a formula or calculator, you could find the lower confidence bound by subtracting the margin of error (ME)

from the sample proportion.

The margin of error can be calculated using the sample proportion, sample size, and the chosen confidence level (in

this case, 99%).

For example, if the sample proportion is 0.25 and the sample size is 100, the margin of error would be 0.075 and the

Answer: $8000r

Step-by-step explanation:

Assuming that both savings accounts earn the same interest rate over the five-year period, Giovanna would have earned the same amount of interest on both accounts.

If she deposited half of the money, which is $1600/2 = $<<1600/2=800>>800, into each account, then the total amount of money she deposited into savings is $800 + $800 = $1600.

Let's say the interest rate on both accounts is r, expressed as a decimal. The amount of interest Giovanna earns on the Oak account after five years would be:

Interest on Oak account = $800 * r * 5

Similarly, the amount of interest she earns on the West United account after five years would be:

Interest on West United account = $800 * r * 5

The total amount of interest she earns from both accounts would be the sum of these two amounts:

Total interest = Interest on Oak account + Interest on West United account

= ($800 * r * 5) + ($800 * r * 5)

= $1600 * r * 5

= $8000r

So, the total amount of interest Giovanna will have earned from both accounts at the end of five years is $8000r. The actual value of r would depend on the interest rate offered by each savings account.

The lowest price of the product that gives a monthly profit of $1550 is $25.

To find the lowest price of the product that gives a monthly profit of $1550, we can substitute P = 1550 into the profit equation P = -x + 105x - 1050 and solve for x.

P = -x + 105x - 1050

1550 = -x + 105x - 1050 (Substitute P = 1550)

1550 + x = 105x - 1050 (Add x to both sides)

x + 1050 = 105x - 1550 (Add 1550 to both sides)

1050 = 105x - x - 1550 (Rearrange terms)

1050 = 104x - 1550 (Combine like terms)

1050 + 1550 = 104x (Add 1550 to both sides)

Answer:

We can break down the total area of grass that Nibbles can nibble into two parts: the original rectangular pen, and the additional grass that Nibbles can reach as the pen is moved.

The area of the original rectangular pen is:

A1 = length x width = 3m x 2m = 6 square meters

To calculate the area of the additional grass, we can visualize the movements of the pen. The pen moves 1 meter to the east, 2 meters to the south, 1 meter to the west, and 2 meters to the north. This creates an irregular pentagon shape, as shown in the diagram below:

```

+-------+

| |

| |

E |

+----+---+ |

| S|

| |

| |

| |

| |

| |

+-----------+

W

```

To calculate the area of this irregular pentagon, we can divide it into two triangles and one rectangle:

- The east and west sides of the pen form a rectangle with dimensions 1m x 2m, for an area of 2 square meters.

- The south side of the pen creates a right triangle with legs of 2m and 1m, for an area of (1/2) x base x height = 1 square meter.

- The north side of the pen creates a right triangle with legs of 2m and 1m, for an area of (1/2) x base x height = 1 square meter.

Therefore, the total area of grass that Nibbles can nibble is:

A = A1 + 2 + 1 + 1 = 10 square meters.

So the answer is 10 square meters.
