tEN Percent of $4.30

Answer:

Probability that 3 out of the next 5 voters approving the proposal is 0.3125.

Step-by-step explanation:

We are given that the sample probability of the voters approving the proposal is 50% and Political scientists want to determine the probability of exactly 3 out of the next 5 voters they meet approving a proposal.

The above situation can be represented through binomial distribution;

[tex]P(X=r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r} ; x = 0,1,2,3,.....[/tex]

where, n = number of trials (samples) taken = 5

            r = number of success = exactly 3

            p = probability of success which in our question is probability of

                  the voters approving the proposal, i.e; p = 50%

Let X = Number of voters approving the proposal

So, X ~ Binom(n = 5 , p = 0.50)

Now, Probability that 3 out of the next 5 voters approving the proposal is given by = P(X = 3)

               P(X = 3)  =  [tex]\binom{5}{3} \times 0.50^{3} \times (1-0.50)^{5-3}[/tex]

                              =  [tex]10 \times 0.50^{3} \times 0.50^{2}[/tex]

                              =  0.3125

Answer:

28 hope this helped

Step-by-step explanation:

20+26+26=72

72+28=100

100/4=25

let the number be X

20 + 26 + 26 + X /4 = 25

72 + X /4 = 25

cross multiply

72 + X = 25*4

72 + X = 100

X = 100.- 72 = 28

X = 28

proof

20 + 26 + 26 +28 / 5 = 25

Answer:

384 cubic meters

Step-by-step explanation:

Think of it as two rectangles on top of each other and then add the two volumes.

Volume is l*w*h

So for the bottom rectangle: (8) (12) (2) = 192 cubic meters

And for the top rectangle: (4)(6)(8) = 192 cubic meters

It is important to remember that for the top box you have to subtract the height of the bottom box which is why I used 4 for the height instead of 6.

Then you add them together.

192+192 = 384 cubic meters

Answer:

The area of sector is [tex]25.12 miles^2[/tex]

Step-by-step explanation:

Radius of circle = 4 miles

We are supposed to find the area of a sector bounded by a 180 arc

[tex]\theta = 180^{\circ}[/tex]

Area of sector =[tex]\frac{\theta}{360^{\circ}} \pi r^2[/tex]

Area of sector = [tex]\frac{180^{\circ}}{360^{\circ}} \times \frac{22}{7} \times 4^2[/tex]

Area of sector = [tex]25.12 miles^2[/tex]

Hence The area of sector is [tex]25.12 miles^2[/tex]

Answer: [tex]-2x^3-14x^2+7x-4[/tex]

Distribute the negative sign.

[tex](3x^3-2x^2+4x-8)-5x^3-12x^2+3x+4[/tex]

Remove the other parentheses.

[tex]3x^3-2x^2+4x-8-5x^3-12x^2+3x+4[/tex]

Combine like terms.

Answer:

area of a rectangle/front side of the box = 100 cm²

Step-by-step explanation:

The prism box is a rectangular prism and the front side of the box will be made of the clear material. The other sides will be made of cardboard paper. The surface area of the side with clear material is only the area of the front side of the box. The area of only the front side is the area of 1 rectangle.

The box has a length of 20 cm , height of 5 cm and a width of 4 cm. The surface area of only the front side of the box which is the area of one rectangle only deals with the height and the length.

area of a rectangle/front side = length × height

where

length = 20 cm

height = 5 cm

area of a rectangle/front side = 20 × 5

area of a rectangle/front side = 100 cm²

Answer:

ZY = 14, SQ= 28

Step-by-step explanation:

Because of "ZR=ZS" and "YR=YQ", so we can apply the Thales theorem:

[tex]\frac{x+2}{3x-8}=\frac{RZ}{RS} =\frac{1}{2} \\[/tex]

so 2(x+2)= 3x-8

2x+4 = 3x-8

2x-3x= -8 -4

-x = -12

or x =12

ZY = x+ 2 = 12+ 2 = 14

SQ= 2*ZY= 2*14 = 28

The answer is B. Loan given for a short period of time that is not dependent on credit history

I just took the quiz and I am big brain.

A loan given for a short period of time that is not dependent on credit history is called a easy - access credit.

Credit is the ability to borrow money or access goods or services with the understanding that you'll pay later.

Given is the easy-access credit.

Easy access credit refers to very short-term and usually very high interest loans. It's a fancy way of saying payday loans, pawn shop transactions, or title loans.

Therefore, a loan given for a short period of time that is not dependent on credit history is called a easy - access credit.

Found answer on brainly.

Answer:

(-1,2)

Step-by-step explanation:

In this problem, the signs are switched because there is a rule to 180 rotation that is (x,y) to (-x,-y).

(1,-2)×(-1x, -1y)= (-1,2) .

Answer:

[tex]\angle L=\angle S[/tex] using congruence rule

Step-by-step explanation:

Given: ΔSAL, SA = LA and AT is the bisector of [tex]\angle A[/tex]

To prove: [tex]\angle L=\angle S[/tex]

Proof:

Two triangles are congruent if they have same shape and same size.

Consider triangles ALT and AST

AL = AS

As AT bisects [tex]\angle A[/tex], [tex]\angle LAT=\angle SAT\\[/tex]

AT = AT (common side)

So, [tex]\Delta ALT\cong \Delta AST[/tex] ( by SAS congruence rule )

Here, SAS denotes side-angle-side

[tex]\angle L=\angle S[/tex] (using corresponding parts of congruent triangles)

Hence proved

Explanation:

First, we know that △ALT ≅ △AST, because of Side Angle Side Theorem. Next, we know that AL ≅ AS, because it's given.

Since A = A, we can remove A and it gives us m∠L = m∠S.

If you need to show work in math terms, your answer should look something like this:

1. △ ALT ≅ △AST - SAS

2. AL ≅ AS - Given

3. m∠ L ≅ m∠S

Answer:

csc x = - [tex]\frac{5}{3}[/tex]

Step-by-step explanation:

Using the trigonometric identity

csc²x = 1 + cot²x

         = 1 + (- [tex]\frac{4}{3}[/tex] )² = 1 + [tex]\frac{16}{9}[/tex] = [tex]\frac{25}{9}[/tex], thus

csc x = ± [tex]\sqrt{\frac{25}{9} }[/tex] = ± [tex]\frac{5}{3}[/tex]

Since 270° < x < 360° where csc x < 0 , then

csc x = - [tex]\frac{5}{3}[/tex]
