Im not sure on this question can someone answer this?

Answer:

[tex]SE_p = 0.055[/tex]

Step-by-step explanation:

Given

[tex]n = 79[/tex] --- Heads

Proportion, p = 46 out of 79

Required

Determine the standard error for sample proportion (SEp)

This is calculated using the following formula

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

In this case:

[tex]p = \frac{46}{79}[/tex]

[tex]p = 0.5823[/tex]

Substitute values for p and n in:

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

[tex]SE_p = \sqrt{\frac{0.5823 * (1-0.5823)}{79}}[/tex]

[tex]SE_p = \sqrt{\frac{0.5823 * 0.4177}{79}}[/tex]

[tex]SE_p = \sqrt{\frac{0.24322671}{79}}[/tex]

[tex]SE_p = \sqrt{0.00307881911}[/tex]

[tex]SE_p = 0.0554871076[/tex]

[tex]SE_p = 0.055[/tex] ---- Approximated

Answer:

P = 26 units

Area =  42 square units.

Step-by-step explanation:

Notice that the points are showing a rectangle with length with a horizontal segment on the coordinate plane that goes from -3.5 to 3.5 (7 units in length), and width a vertical segment from -3 to 3 (6 units in length).

Therefore the rectangle's perimeter (P) is:

P = 2 L + 2 W = 2* 7 + 2 * 6 = 14 + 12 = 26 units.

The area of the rectangle is given by:

Area = L * W = 7 * 6 = 42 square units.

Answer:

d. is constructed by totaling a set of data and dividing that total by the number of observations  

Step-by-step explanation:

Moving average is a method of calculation that is use to analyze the data points by making a series of averages of the various subsets in the full data set. Its another name is rolling average or moving mean.

A simple moving average is constructed by taking the sum of a set of data and then dividing the total by a number of the observations.

Answer:

C) 4+9i

Step-by-step explanation:

A complex number is represented as: [tex]a + bi[/tex].

Where:  [tex]a \to[/tex] Real part and      

[tex]bi \to[/tex] Imaginary part

From the given numbers, [tex]4 + 9i[/tex] is a complex number

The given numbers are:

[tex]-7[/tex]

[tex]2 + \sqrt 3[/tex]

[tex]4 + 9i[/tex]

[tex]\pi[/tex]

By comparing [tex]a + bi[/tex] with the given numbers;

We can conclude that: [tex]4 + 9i[/tex] is a complex number

Because it has a real part (4) and an imaginary part (9i)

Answer:

6399/9=711 The answer to this question is 711.

Answer:

[tex]Area = 968000cm^2[/tex]

Step-by-step explanation:

To be able to answer this question properly. I'll assume the length of the room is in meters.

So for the room, we have:

[tex]Length = 12.8m[/tex]

[tex]Breadth = 850cm[/tex]

For the bed, we have:

[tex]Length = 300cm[/tex]

[tex]Breadth = 400cm[/tex]

First, we calculate the surface area of the room.

[tex]A_1 = 12.8m * 850cm[/tex]

Convert all units to cm

[tex]A_1= 12.8*100cm * 850cm[/tex]

[tex]A_1= 1 088 000 cm^2[/tex]

Next, we calculate the area of the bed

[tex]A_2 = 300cm * 400cm[/tex]

[tex]A_2 = 120000cm^2[/tex]

The area of the space left  is the difference between A1 and A2

[tex]Area = A_1 - A_2[/tex]

[tex]Area = 1088000cm^2 - 120000cm^2[/tex]

[tex]Area = 968000cm^2[/tex]

Step-by-step explanation:

An isosceles triangle has two sides that are equal. ∆ABC has two equal sides. Thus, the angles opposite the two sides of an isosceles triangle are also congruent to each other.

<C and <A are congruent to each other.

m<A = 56°, therefore,

m<C = 56°

Answer:

y = 1.6x

Step-by-step explanation:

y is the total amount/pounds of almonds that Lark bought. x is the amount that Tessa bought. 3/5 is the same as 0.6. If we multiplied Tessa's amount by 0.6 it would decrease by 2/5 so we have to add 1 to make it 1.6. To find how much Lark bought multiply 1.6 and Tessa's amount.

Answer:

  $750

Step-by-step explanation:

The 20% discount multiplies the price by (1 - 20%) = 0.80.

The 15% discount multiplies the price by (1 - 15%) = 0.85.

After applying the discounts to the initial price P, we have ...

  P(0.80)(0.85) = $510

  P = $510/(0.80·0.85) = $750

The price before discounts was $750.

Option C corresponds to the vectors scalar projection and dot product, which are uv = 2.24 and u v = 7.07.

To find the scalar projection (uv) and the dot product (u · v) of vectors u and v, use the following formulas:

Scalar Projection (uv) of u onto v:

uv = |u| × cos(ϴ)

Dot Product (u · v) of u and v:

u · v = |u| × |v| × cos(ϴ)

u = ⟨1, 3⟩ and v = ⟨2, 1⟩, and cos(ϴ) = √(2)/2,

calculate the magnitudes of u and v first:

|u| = √(1² + 3²) = √10

|v| = √(2² + 1²) = √5

Now, calculate the scalar projection (uv) and the dot product (u · v):

Scalar Projection (uv) of u onto v:

uv

= |u| × cos(ϴ)

= √10 × √(2)/2

= √(10/2)

= √5 ≈ 2.24

Dot Product (u · v) of u and v:

u · v

= |u| × |v| × cos(ϴ)

= √10 × √5 × √(2)/2

= √(1052)/2

= √100/2

= √50

≈ 7.07

Therefore, the scalar projection and dot product of the vectors is equal to option c. uv = 2.24 and u · v = 7.07.
