A sailboat is 175 feet from the base of a lighthouse. If the angle of elevation to the top of the lighthouse is 23°, find the height of the lighthouse, to the nearest hundredth of a foot.

Answer:

Its either 60.625 or 90

Step-by-step explanation:

((2470 - 470)/16) - 35

(2000/16) - 35

125 - 35

90

90 is true if you made a mistake in adding two 470's, but if this is the actual equation, it is 60.625

(or when you follow the order of the numbers it becomes the 61 number)

The standard error of the sample proportion is 0.0002275

The standard error of a proportion p in a sample of size n is given by:

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

Now it is given that,

Number of people selected is 1000.

So, sample size, n 1000

Americans prefer chocolate = 65%

Thus, proportion, p = 0.65

So, standard error of a proportion is given as,

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

[tex]S= \sqrt{\frac{0.65(1-0.65)}{1000}}[/tex]

[tex]S= \sqrt{\frac{0.65(0.35)}{1000}}[/tex]

[tex]S= \sqrt{\frac{0.2275}{1000}}[/tex]

[tex]S= 0.0002275[/tex]

this is the required standard error of the sample proportion.

Thus, the standard error of the sample proportion is 0.0002275.

Answer:

4x and -2x

Step-by-step explanation:

Answer:

The like terms are 4x and 2x.

Step-by-step explanation:

4x and 2x have x as their variable.

Ignore the negative sign, since that only affects the sign of the final product

3415₇ × 432₇

You can compute the product by considering the digit expansion, by which I mean first expanding each number as sums of powers of 7:

3415₇ = 3000₇ + 400₇ + 10₇ + 5₇

(It's the same thing as writing, for example, the decimal 3415 as 3000 + 400 + 10 + 5, just in a different base.)

Similarly,

432₇ = 400₇ + 30₇ + 2₇

Then apply the distributive property:

= (3000₇ + 400₇ + 10₇ + 5₇) × (400₇ + 30₇ + 2₇)

= 3000₇ × (400₇ + 30₇ + 2₇)

… + 400₇ × (400₇ + 30₇ + 2₇)

… + 10₇ × (400₇ + 30₇ + 2₇)

… + 5₇ × (400₇ + 30₇ + 2₇)

= {12}00000₇ + {9}0000₇ + 6000₇

… + {16}0000₇ + {12}000₇ + {8}00₇

… + 4000₇ + 300₇ + 20₇

… + {20}00₇ + {15}0₇ + {10}₇

where I use the curly braces to indicate products (written in base 10) of digits that exceed 6. Anything in these braces needs to be properly converted to base 7. For example,

{12}₇ = 7 + 5 = 15₇

So you would have

= 1500000₇ + 120000₇ + 6000₇

… + 220000₇ + 15000₇ + 1100₇

… + 4000₇ + 300₇ + 20₇

… + 2600₇ + 210₇ + 13₇

Add everything up:

• In the 7⁰ place,

3₇

• In the 7¹ place,

1₇ + 1₇ + 2₇ = 4₇

• In the 7² place,

2₇ + 6₇ + 3₇ + 1₇ = {12}₇ = 15₇

• Carry the 1 (underlined). In the 7³ place,

2₇ + 4₇ + 1₇ + 5₇ + 6₇ + 1₇ = {19}₇ = 25₇

• Carry the 2. In the 7⁴ place,

1₇ + 2₇ + 2₇ + 2₇ = {7}₇ = 10₇

• Carry the 1. In the 7⁵ place,

2₇ + 1₇ + 5₇ + 1₇ = {9}₇ = 12₇

• Carry the 1. In the 7⁶ place,

1₇ + 1₇ = 2₇

So, we end up with

3415₇ × 432₇ = 22045543₇

and thus

3415₇ × (-432₇) = -22045543₇

Answer:

7 metre

Step-by-step explanation:

Let the breadth of the room is x.m. , then the length is (x+2).m. , accordingly:-

(x+2).x. = 63.

or, x^2 +2 x - 63 = 0.

or, (x + 9).(x -7) =0.

or, x = - 9 (not valid) , 7 .

Thus , the length = (x+2).m.= (7+2) = 9.m. , breadth = x .m. = 7.m. , Answer.

If you look at the question, You would see a pattern. That pattern is the amount of slices in one week is divided by 2 the next week. So on the fourth week you would do 320/2 and get 160. if you keep carrying on the pattern yourself, you would do: 160/2 = 80. 80/2 = 40. And there's your answer. week 4 we had 160 slices sold. week 5 80 slices sold. Week 6 40 slices sold

Standard Deviation Percentage Area

The percentages associated with each unit of standard deviation are all 0, since the standard normal curve is symmetric and the area under the curve for each interval of the same length and equidistant from the mean is equal.

A standard deviation is a measure of how far apart the data is from the mean.

The table shows the area under the standard normal curve for different values of x, where x is the number of standard deviations from the mean.

To find the percentage associated with each unit of standard deviation, we can subtract the area from the table for the lower value of x from the area for the higher value of x, and round the result to the nearest hundredth.

For example, the percentage associated with one unit of standard deviation, from -1 to 0 or from 0 to +1, is:

Area from -1 to 0: 0.3413

Area from 0 to +1: 0.3413 (symmetric curve)

Percentage: 0.3413 - 0.3413 = 0 (rounded to nearest hundredth)

The percentage associated with two units of standard deviation, from -2 to 0 or from 0 to +2, is:

Area from -2 to 0: 0.4772

Area from 0 to +2: 0.4772 (symmetric curve)

Percentage: 0.4772 - 0.4772 = 0 (rounded to nearest hundredth)

Similarly, we can find the percentages associated with other units of standard deviation:

From -3 to 0 or from 0 to +3: 0.4987 - 0.4987 = 0

From -4 to 0 or from 0 to +4: 0.4999 - 0.4999 = 0

Therefore, because the standard normal curve is symmetric and the area under the curve for each interval of the same length and equidistant from the mean is equal, the percentages associated with each unit of standard deviation are all zero.
