Answer:

  30.0 ft

Step-by-step explanation:

You want the length of a pole whose shadow is 20 ft long when the angle of elevation of the sun is 62° and the pole is tilted 8° away from the sun.

Referring to the attached diagram, we see that the interior angle at B of triangle ABC is 90° -8° = 82°. This makes the interior angle at A ...

  A = 180° -82° -62° = 36°

The law of sines tells us side lengths are proportional to the sines of the opposite angles:

  c/sin(C) = a/sin(A)

  c = a×sin(C)/sin(A) = 20×sin(62°)/sin(36°) ≈ 30.043 . . . feet

The length of the pole is about 30.0 feet.

Answer:

[tex]y = \frac{ - 1}{2} *\sqrt{x-1} - 5[/tex]

Step-by-step explanation:

The standard equation of a square root function with vertex at point (h,k) is given by:

[tex]y = a \times \sqrt{x - h} + k[/tex]

where (h,k) is the vertex and "a" is a coefficient that determines the vertical stretch and direction of the square root function.

We know that the vertex of our square root function is (1, -5), so we can substitute those values into the equation to get:

y = [tex] a*\sqrt{x-1} - 5[/tex]

Now, we need to find the value of "a". To do that, we will use the fact that the square root function passes through point (5, -7). Substituting these coordinates into the equation, we get:

[tex]-7 = a*\sqrt(5-1) - 5[/tex]

-2 = 4a

[tex]a = \frac{ - 1}{2} [/tex]

Now that we know the value of "a", we can substitute it into our equation to get the final equation of the square root function:

[tex]y = \frac{ - 1}{2} *\sqrt{x-1} - 5[/tex]

Therefore, the equation of the square root function with a vertex at (1, -5) and passing through (5, -7) is

[tex]y = \frac{ - 1}{2} *\sqrt{x-1} - 5[/tex]

Answer:

[tex]f(x) = -\sqrt{x-1} - 5[/tex]

Step-by-step explanation:

The standard form of a square root function is:

[tex]f(x)=a\sqrt{x-h}+k[/tex]

where "a" is a scaling factor determining the vertical stretch or compression of the function, and (h, k) is the vertex.

Given the vertex is (1, -5), substitute h = 1 and k = -5 into the equation:

[tex]f(x) = a\sqrt{x - 1} - 5[/tex]

Substitute the point (5, -7) that the function passes through to find the stretch factor "a":

[tex]\begin{aligned}-7 &= a \sqrt{5 - 1} - 5\\-7 &= a \sqrt{4} - 5\\-7 &= 2a - 5\\-7 +5&= 2a - 5+5\\-2&= 2a\\\dfrac{-2}{2}&=\dfrac{2a}{2}\\-1&=a\\a &= -1\end{aligned}[/tex]

Substitute the value of "a" back into the equation:

[tex]f(x) = -\sqrt{x-1} - 5[/tex]

Therefore, the equation of the square root function with a vertex at (1, -5) and passes through the point (5, -7) is:

[tex]\boxed{f(x) = -\sqrt{x-1} - 5}[/tex]

  C. 10

Step-by-step explanation:

You want to know the bin size in a histogram with bin boundaries 10.5, 20.5, 30.5, ....

The size of the bin is the difference between its boundary values. Here, all of the bins are the same size:

  20.5 -10.5 = 10

The bin size is 10.

__

Additional comment

The bin boundaries are typically chosen so that no data value can fall on the boundary, but must be unambiguously allocated to one bin or another. When the data values are integers, it is not uncommon to have the bin boundary be halfway between two integers.

Here, the boundary being 20.5 means a score of 20 will be counted in the bin to the left, and 21 will be counted in the bin to the right.

The boundary value shown at the right edge of the graph is not 100.5, as we might expect. However, we can reasonably assume that a test score of 100 would be counted in the bin with upper boundary 100, without any ambiguity.

-6 1 2

-4 -5 9

8 -3 -2

To check if this is a magic square, we can calculate the sum of each row, column, and diagonal:

Rows:

(-6 + 1 + 2) = -3

(-4 - 5 + 9) = 0

(8 - 3 - 2) = 3

Columns:

(-6 - 4 + 8) = -2

(1 - 5 - 3) = -7

(2 + 9 - 2) = 9

Diagonals:

(-6 - 5 - 2) = -13

(2 - 5 + 8) = 5

All of these sums are equal to 0, so this is indeed a magic square.

Answer:

m = 476

Step-by-step explanation:

m + 310 = 786

(Subtract 310 from both sides.)

m = 786 - 310

(Subtract 310 from 786 to get 476)

m = 476

Answer:

We can use the formula to find the length of a circular arc given the measure of the central angle and the radius:

Length of arc = (central angle measure / 360) x 2πr

where r is the radius of the circle.

Given that the central angle measure is 40° and the length of the arc is 6 cm, we can set up the equation:

6 = (40/360) x 2πr

Simplifying the fraction and solving for r, we get:

6 = (1/9) x 2πr

r = 9 x 6 / 2π

r = 27/π

So the radius of the circle is 8.59 cm (rounded to two decimal places).

There is enough data to indicate that Jordanian children are at risk of anemia.

The null hypothesis is that the true mean hemoglobin level for Jordanian children is greater than or equal to 12 g/dl, and the alternative hypothesis is that it is less than 12 g/dl.

Using the P-value method:

The test statistic for the one-sample t-test is given by:

t = (x - μ) / (s / √n)

where x is the sample mean, μ is the population means (here, μ = 12), s is the sample standard deviation, and n is the sample size.

Substitute the given values,

t = (11.3 - 12) / (1.6 / √50) = -2.98

Using a t-distribution table with 49 degrees of freedom (df = n - 1), find that the p-value for this test is approximately 0.002.

Since the p-value is less than the significance level of α = 0.05, we reject the null hypothesis and conclude that there is sufficient evidence to support the claim that Jordanian children are at risk of anemia.

Answer:

632.83mm²

Step-by-step explanation:

Applying Pythagorean theorem to triangle SOH

SH² = SO² + OH²

SH = [tex]\sqrt{(15.4)^2+(7.2)^2}=17mm[/tex]

Since the base of the pyramid is a regular pentagon, angle OAH
is 108°/2 = 54°.

AH = 7.2/tan 54° = 5.23mm

So AB = 2AH = 10.46mm

The area of triangle SAB is:

A1 = 1/2 × SH × AB = 1/2 × 17 × 10.46 = 88.91mm²

The area of all triangles is

A2 = 5 × A1 = 5 × 88.91 = 444.55mm²

The area of the base is:

A3 = (perimeter × apothem)/2 = (5 × 10.46 × 7.2)/2 = 188.28mm²

The surface area of the pyramid is:

A2 + A3 = 444.55 + 188.28 = 632.83mm²

Step-by-step explanation:

the surface area is the sum of the base area (pentagon) and the 5 side triangles (we only need to calculate one and then multiply by 5, as they are all equal).

these side triangles are isoceles triangles (the legs are equally long).

the usual area formula for a pentagon is

1/2 × perimeter × apothem

the apothem is the minimum distance from the center of the pentagon to each of its sides.

in our case this is 7.2 mm.

how to get the perimeter or the length of an individual side of the pentagon ?

if the apothem of a pentagon is given, the side length can be calculated with the formula

side length = 2 × apothem length × tan(180/n)

where 'n' is the number of sides (5 in our case). After getting the side length, the perimeter of the pentagon can be calculated with the formula

perimeter = 5 × side length.

so, in our case

side length = 2 × 7.2 × tan(180/5) = 14.4 × tan(36) =

= 10.4622124... mm

perimeter = 5 × 10.4622124... = 52.31106202... mm

area of the pentagon = 1/2 × perimeter × apothem =

= 1/2 × 52.31106202... × 7.2 = 188.3198233... mm²

now for the side triangles.

the area of such a triangle is

1/2 × baseline × height

baseline = pentagon side length

height we get via Pythagoras from the inner pyramid height and the apothem :

height² = 7.2² + 15.4² = 51.84 + 273.16 = 289

height = 17 mm

area of one side triangle =

1/2 × 10.4622124... × 17 = 88.92880543... mm²

all 5 side triangles are then

444.6440271... mm²

and the total surface area is then

444.6440271... + 188.3198233... = 632.9638504... mm²

≈ 632.96 mm²

Answer:

124

Step-by-step explanation:

To find the number that should be added to the data so that the range of the data is 63, we first need to find the current range of the data.

The range of a set of data is the difference between the largest and smallest values in the set.

So, to find the current range of the data, we need to subtract the smallest value from the largest value:

Range = largest value - smallest value

Range = 97 - 61

Range = 36

This means that the current range of the data is 36.

To increase the range to 63, we need to add a number that is 63 - 36 = 27 larger than the current range.

To do this, we can add 27 to the largest value in the data set, which is 97:

97 + 27 = 124

So, we should add 27 to the data set to increase the range to 63.

Therefore, the complete set of data would be:

78, 61, 95, 77, 85, 97, 124

Check:

To find the range of the data set 78, 61, 95, 77, 85, 97, 124, we need to subtract the smallest value from the largest value:

Range = largest value - smallest value

Range = 124 - 61

Range = 63

Therefore, the range of the data set 78, 61, 95, 77, 85, 97, 124 is 63.

Step-by-step explanation:

you can find the answer by vertical opposite angle

if the value of x is computed and it's equal to 78 you will find the answer

If the standard error is 33.64, the size of the margin of error at 95% confidence is 65.93. So, correct option is D.

The margin of error (ME) can be calculated using the formula:

ME = z* (standard error)

where z is the z-score from the standard normal distribution corresponding to the desired level of confidence. For 95% confidence, z is 1.96.

Substituting the values given in the problem, we have:

ME = 1.96 * 33.64 = 65.93

Therefore, correct option is D.

This means that if we take multiple random samples of size 121 from the population, and calculate the sample mean and confidence interval for each sample, we can expect the true population mean to fall within 65.93 units above or below the sample mean, 95% of the time.
