Luis and Jasmine are making scale drawings of the front of their school for an art contest. Luis uses the scale 3 in. to 10 ft. Jasmine uses the scale 5 in. to 20 ft. The tree in front of the school in Luis's drawing is 7.5 inches tall. How tall is the tree in Jasmine's drawing?

Answer:

A. 145°

Step-by-step explanation:

<4 = 35° (given)

m<6 + m<4 = 180° (same side interior angles are supplementary)

Thus:

m<6 + 35° = 180° (substitution)

m<6 + 35° - 35° = 180° - 35° (subtraction property of equality)

m<6 = 145°

Answer:

the subtraction property of equality

Step-by-step explanation:

We use the "subtraction property of equality" to solve for the unknown in the equation:

c + 5 = 78

subtract 5 from both sides:

c + 5 - 5 = 78 - 5

c = 73

The length of Marisa's garden is 10

The given parameters are:

Perimeter = 32 feet

Width = 6 feet

The perimeter is calculated as:'

Perimeter = 2 * (Length + width)

So, we have

2 * (Length + 6) = 32

Divide by 2

Length + 6 = 16

Subtract

Length = 10

Hence, the length of Marisa's garden is 10

Considering the given figure angle 1 is calculated to be 26

The solution of angle 1 is gotten from the knowledge of adjacent angles

angle 1 and angle 2 are adjacent angles and the total angle is given to be x + 38

therefore  we have

x + 38 = angle 1 + angle 2

x + 38 = angle 1 + x + 12

angle 1 = x + 38 - x - 12

angle 1 = 38 - 12

angle 1 = 26

we can therefore say that angle 1 is 26

Here is the full question.

Calculate the mean and the standard deviation of the sampling distribution of possible sample proportions for each combination of sample size (n) and population proportion (p).

a.) n = 64, p = 0.8

b.) n = 256, p = 0.8

Answer:

a.) Mean = 0.8

   Standard deviation = 0.05

b.)  Mean = 0.8

     Standard deviation = 0.025

Step-by-step explanation:

From the given information:

a.)

The population parameter (p) is the mean of the sampling distribution for the sample proportion.

Thus; The  Mean = 0.8

The standard deviation of the  distribution can be calculated as follows:

Let's first represent the standard deviation with Sd(\(\hat p\))

Then:

\(sd(\hat p) = \sqrt{\dfrac{p*(1-p)}{n} }\)

where;

p = 0.8

n = 64

Then:

\(sd(\hat p) = \sqrt{\dfrac{0.8*(1-0.8)}{64} }\)

\(sd(\hat p) = \sqrt{\dfrac{0.8*(0.2)}{64} }\)

\(sd(\hat p) = \sqrt{\dfrac{0.16}{64} }\)

\(sd(\hat p) = \sqrt{0.0025}\)

\(\mathbf{sd(\hat p) =0.05}\)

b.)

The population parameter (p) is the mean of the sampling distribution for the sample proportion.

Thus; The  Mean = 0.8

The standard deviation of the  distribution can be calculated as follows:

Let's first represent the standard deviation with Sd(\(\hat p\))

Then:

\(sd(\hat p) = \sqrt{\dfrac{p*(1-p)}{n} }\)

where;

p = 0.8

n = 256

Then:

\(sd(\hat p) = \sqrt{\dfrac{0.8*(1-0.8)}{256} }\)

\(sd(\hat p) = \sqrt{\dfrac{0.8*(0.2)}{256} }\)

\(sd(\hat p) = \sqrt{\dfrac{0.16}{256} }\)

\(sd(\hat p) = \sqrt{6.25 \times 10^{-4}}\)

\(\mathbf{sd(\hat p) =0.025}\)

The standard deviation of death in an army corps each year is 0.78

From the question, we have the following parameters that can be used in our computation:

Distribution type = Poisson distribution

Average of the distribution = 0.61

The standard deviation of the distribution is calculated as:

Standard deviation = √Average of the distribution

Substitute the known values in the above equation, so, we have the following representation

Standard deviation = √0.61

Evaluate the square root expression

So, we have

Standard deviation = 0.78

Hence, the standard deviation is 0.78

The sum of the arithmetic sequence is S = 207 and the summation notation is S = ∑i=1 to 6 ( 5n + 17 )

An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Given data ,

Let the arithmetic sequence be represented as A

Now , the value of A is

A = 22 + 27 + 32 + 37 + 42 + 47

The number of terms n = 6

So , the value of i ranges from 1 to 6

Now , the summation is represented as ∑i=1 to 6 ( 5n + 17)

when n = 1

S₁ = 5 ( 1 ) + 17 = 22

when n = 2

S₂ = 22 + 5 ( 2 ) + 17

S₂ = 22 + 27

when n = 3

S₃ = 22 + 27 + 5 ( 3 ) + 17

S₃ = 22 + 27 + 32

Hence , the sum of the arithmetic sequence is S = 207

2. 8n. 8n. 8n. 8n

Step-by-step explanation:

\(2 {(8n)}^{4} = 2. 8n. 8n. 8n. 8n\)

Equivalent expressions are expressions with equal value.

The equivalent expression of \(\mathbf{2\cdot(8n)^4}\) is \(\mathbf{2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}\)

The expression is given as:

\(\mathbf{2\cdot(8n)^4}\)

Apply law of indices

\(\mathbf{2\cdot(8n)^4 = 2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}\)

The above equation means that:

\(\mathbf{2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}\) is equivalent to \(\mathbf{2\cdot(8n)^4}\)

Hence, the correct option is (d) \(\mathbf{2\cdot(8n)\cdot(8n)\cdot(8n)\cdot(8n)}\)
