Answer: A. 9

Step-by-step explanation:

In the given tree diagram , there are 3 branches , to each branch there are 3 leaf nodes.

By using Fundamental counting principal ,

Number of possible outcomes for the tree diagram = (Number of branches) x (Number of leaf nodes)

[tex]=3 \times 3\\\\=9[/tex]

Hence, the number of possible outcomes for the tree diagram = 9

So, the correct option is A. 9.

Answer:

a. Distance = 400 - 200t

b. see attached graph

c. A travelled 180 km, B travelled 220 km, both took 2 hours.

Step-by-step explanation:

Given

distance = 400

A = 90 km/h

B = 110 km/h

A & B drive towards each other

Solutions

a) equation

Let

t = elapsed time in hours,

D(t) = distance between two drivers

D(t) = 400 - (A+B) t  

D(t) = 400 - 200t  ......................(1)

b. graph : for graph, see attached figure.

c. Distance and time

Time:

solve for t with the distance D(t) = 0 using equation (1)

0 = 400 - 200 t

200t = 400

t = 2   hours

distance travelled by A = 2 hours * 90 km/h  = 180 km

distance travelled by B = 2 hours * 110 km/h  = 220 km

Answer: 169 m²

Step-by-step explanation:

The area of a square can be found by taking a side length(13), and squaring it, to get, in this case, 139.

Hope it helps <3

Answer:

169 m²

Step-by-step explanation:

To find the area of a square, we can apply a formula.

[tex]A=s^2[/tex]

[tex]A=area[/tex]

[tex]s=side \: length[/tex]

The side length is given 13 meters.

[tex]A=13^2[/tex]

Solve for [tex]A[/tex].

[tex]A=13 \times 13[/tex]

[tex]A=169[/tex]

The area of the square is 169 meters squared.

Answer:

the expression of this function is:

[tex]f(x)=|x-1|-1[/tex]

Step-by-step explanation:

This graph corresponds to an absolute value function, which as you can see has the minimum (vertex) at the point (1, -1) on the plane, and also that goes through the origin of coordinates (0, 0)

therefore, notice that from the point (0, 0) to (1, -1) there is a slope of "-1" which is going to characterize the steepness of the x- variable that resides inside the absolute value function. since the vertex has also moved from the characteristic (0, 0) in the function:

[tex]f(x)=|x|[/tex]

then we have to include a horizontal shift to the right in one unit (by subtracting 1 units from x), and a vertical shift  downwards one unit (by subtracting 1 from the full absolute value expression) in order to shift the vertex to the position (1, -1):

[tex]f(x)=|x-1|-1[/tex]

Answer:

Below in bold.

Step-by-step explanation:

24 ÷ [ 33- (1+2)^2]

= 24 / ( 33 - 3^2)

= 24 / 24 = 1.

21 + 3 (2-2^2)

= 21 + 3(2 - 4)

= 21 + 3 * -2

= 21 - 6

= 15.

[(14+√4)÷2^3] - 14

= [ (14 + 2) / 8] - 14

= 16/8 - 14

= 2 - 14

= -12.

20 + [18÷(4+1)] - (3^2 + 2)

= 20 + [18÷ 5] - (9 + 2)

= 20 + 3.6 - 11

= 23.6 - 11

= 12.6.

Simplify equation:     14 - 7y + 5 = 1 + 3y + 24

     simplify again:  19 - 7y = 25 + 3y

     add -25  and 7y to both sides:   -6 = 10y

     y = -6/10   or -0.6

2.  After 30 minutes, richie has delivered 1/3 of the papers, so they have to deliver the remaining 2/3.  Since they can deliver them all in 40 minutes, would the answer be 2/3 of 40?  I'm not sure about this.

Answer: (0.4016, 0.4984).

Step-by-step explanation:

Let p be the proportion of voters will vote for Candidate A for president.

Formula for confidence interval for proportion:

[tex]\hat{p}\pm z^*\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex]

, here [tex]\hat{p}[/tex]= sample proportion

n= sample size.

z* =two-tailed critical z- value.

As per given, we have

n= 700

[tex]\hat{p}[/tex] = 0.45

Critical two-tailed z-value for 99% confidence interval = 2.576

Then, the required 99% confidence interval for p would be:

[tex]0.45\pm (2.576)\sqrt{\dfrac{0.45(1-0.45)}{700}}\\\\=0.45\pm(2.576)\sqrt{0.000353571428}\\\\=0.45\pm (2.576)(0.0188035)\\\\=0.45\pm0.04844\\\\=(0.45-0.048437,\ 0.45+0.048437)\\\\=(0.401563,\ 0.498437)\approx(0.4016,\ 0.4984)[/tex]

Hence, the required confidence interval (0.4016, 0.4984).

Answer:

Standard deviation=4

Step-by-step explanation:

Standard deviation = square root of variance

Standard deviation=√variance

Variance=standard deviation square

Variance=standard deviation^2

From the question

Variance=16

Standard deviation=?

Standard deviation=√variance

=√16

=4

Standard deviation=4

check:

If standard deviation=4

Variance=standard deviation^2

=4^2

=16

Therefore,

Standard deviation=√variance

[tex]4[/tex]

Variance of the variable [tex]=16[/tex]

Standard deviation [tex]=\sqrt{16}[/tex]

                                [tex]=\boldsymbol{4}[/tex]

Answer: {-7, 2}

Step-by-step explanation: This type of equation is called a polynomial equation and in order to solve for x, we would first factor the left side.

Notice that the left side of the equation is a trinomial in a special

form that can be factored as he product of two binomials.

As our first term for each binomial, we have the factors of x², x · x

and as the second term, we have the factors of -14 that add to 5.

In this case, the factors are +7 and -2.

So we have (x + 7)(x - 2) = 0.

If (x + 7)(x - 2) = 0, that means that either x + 7 = 0 or x - 2 = 0.

Solving for x in each equation, we have x = -7 or x = 2.

We can write our answer as the solution set {-7, 2}.

The solution of quadratic equation is,

⇒ x = - 7, 2

We have to given that,

An equation is,

⇒ x² + 5x - 14 = 0

We can factorized the above quadratic equation as,

⇒ x² + 5x - 14 = 0

⇒ x² + (7 - 2)x - 14 = 0

⇒ x² + 7x - 2x - 14 = 0

⇒ x (x + 7) - 2 (x + 7) = 0

⇒ (x + 7) (x - 2) = 0

This gives,

x + 7 = 0

x = - 7

x - 2 = 0

x = 2

Therefore, The solution of quadratic equation is,

⇒ x = - 7, 2

Answer:

a) 6

Step-by-step explanation:

Expanding the polynomial using the formula:

[tex]$(x+y)^n=\sum_{k=0}^n \binom{n}{k} x^{n-k} y^k $[/tex]

Also

[tex]$\binom{n}{k}=\frac{n!}{(n-k)!k!}$[/tex]

I think you mean [tex]210x^6y^4[/tex]

We can deduce that this term will be located somewhere in the middle. So I will calculate [tex]k= 5; k=6 \text{ and } k =7[/tex].

For [tex]k=5[/tex]

[tex]$\binom{10}{5} (y)^{10-5} (x)^{5}=\frac{10!}{(10-5)! 5!}(y)^{5} (x)^{5}= \frac{10 \cdot 9 \cdot 8 \cdot 7 \cdot 6 \cdot 5! }{5! \cdot 5 \cdot 4 \cdot 3 \cdot 2 \cdot 1 } \\ =\frac{30240}{120} =252 x^{5} y^{5}$[/tex]

Note that we actually don't need to do all this process. There's no necessity to calculate the binomial, just [tex]x^{n-k} y^k[/tex]

For [tex]k=6[/tex]

[tex]$\binom{10}{6} \left(y\right)^{10-6} \left(x\right)^{6}=\frac{10!}{(10-6)! 6!}\left(y\right)^{4} \left(x\right)^{6}=210 x^{6} y^{4}$[/tex]

Answer:

Equation y = -2x -3

Step-by-step explanation:

(1,-1) (3,-5)

Slope = -5-(-1) / 3-1 = -5+1/2 = -4/2 = -2

y = mx + K

-1 = -2(1) + k

-1 = -2 + k

k = 1

Equation y = -2x+1

Answer:

Step-by-step explanation:

slope=(y2-y1)/(x2-x1)=(-5-(-1))/(3-1)=(-5+1)/2=-4/2=-2

y-y1=m(x-x1)

y-(-1)=-2(x-1)

y+1=-2(x-1)

y+1=-2x+2

y=-2x+2-1

y=-2x+1
