Answer:

(-4,-1)

Step-by-step explanation:

-3x+10y=2

-3x+3y=9

-3x=2-10y

-3x=9-3y

2-10y=9-3y

2-9=10y-3y

7y=-7

y=-1

-3x+3(-1)=9

-3x-3=9

-3x=12

x=-4

Answer:

X=4, y=-1

Step-by-step explanation:

-3x+10y=2 multiple by 3

-3x+3y=9 multiply by 10

9x+30y=6

30x+30y=90

Subtract equation 1 from 2

30x-9x+30y-30y=90-6

21x+0=84

21x=84

Divide both side by 21

X=4

Substitute 4 for x in equation 1

3x+10y=2

3(4)+10y=2

12+10y=2

10y=2-12

10y=-10

Divide both side by 10

Y=-1

Answer:

6, 13 and 14

Step-by-step explanation:

Answer:

100.3 units²

Step-by-step explanation:

Area of the figure = area of two semicircles + area of a parallelogram

= 2(½*πr²) + b*h

Where,

Radius (r) = ½ of 8 = 4

Base (b) = 10

Height (h) = 5

Plug in the values

Area of figure = 2(½*π*4²) + 10*5

= 16π + 50

Area = 100.265482

Area of figure = 100.3 units² (nearest tenth)

The mode of the following number of countries randomly selected travelers visited in the past two years is 13.

Step-by-step explanation:

The mode of a data-set is the value that appears the most commonly, the most frequently.

In this data-set:

13 appears 3 times

7 and 4 twice

The others once

So 13 is the mode.

Answer:

(2^-14 * 5^10)

Step-by-step explanation:

(2^-7 * 5^5)^2

From.the law of indices :

(a^m)^n = a^mn

Such that we multiply both powers

Hence the equation, W will become :

2^(-7*2) * 5^(5*2) = (2^-14 * 5^10)

Answer:

to find the Area of a Triangle, you have to multiply the base times the height of the triangle to find the Area.

Step-by-step explanation:

For example..

If the Base ( bottom part of the triangle) was 10 and the height ( the vertical line of the triangle) was 5, you would multiply them together to get 50. So 5o would be the area of the Triangle.

Answer:

1/2 x b x h

Step-by-step explanation:

b= base

h= hieght

1.  Multiply your base by 1/2

2. Then multiply the sum of that by your hieght

Ex: A trianle with a base of 18 and hieght of 4

1. 1/2 x 18 = 9

2. 9 x 4 = 36

Answer:

63 inches

Step-by-step explanation:

the diameter is the entire line across the circle, the things needed to find out the circumference of the circle are the radius. that means you would divide your diameter in half to get 10. after you done that, you would input that into the equation:

c=2Π10

that would get you about 62.83 or 63

Answer:

Sample space S = {0,1,2,3,4,5}

Step-by-step explanation:

We all know that when a dice is tossed, the minimum value that can be obtained is 1 and the maximum value that can be obtained is 6.

Now, when two dice are tossed, the possible cases are:

[tex]= \left\{\begin{array}{cccccc}(1,1)&(1,2)&(1,3) &(1,4)&(1,5)&(1,6)\\(2,1)&(2,2)&(2,3) &(2,4)&(2,5)&(2,6)\\(3,1)&(3,2)&(3,3) &(3,4)&(3,5)&(3,6)\\(4,1)&(4,2)&(4,3) &(4,4)&(4,5)&(4,6)\\(5,1)&(5,2)&(5,3) &(5,4)&(5,5)&(5,6)\\(6,1)&(6,2)&(6,3) &(6,4)&(6,5)&(6,6)\end{array}\right\}[/tex]

However, the magnitude of the difference in no. of dots showing up in the two dice is:

[tex]= = \left\{\begin{array}{cccccc}(1,1)=0&(1,2)=1&(1,3)=2 &(1,4)=3&(1,5)=4&(1,6)=5\\(2,1)=1&(2,2)=0&(2,3)=1 &(2,4)=2&(2,5)=3&(2,6)=4\\(3,1)=2&(3,2)=1&(3,3)=0 &(3,4)=1&(3,5)=2&(3,6)=3\\(4,1)=3&(4,2)=2&(4,3)=1 &(4,4)=0&(4,5)=1&(4,6)=2\\(5,1)=4&(5,2)=3&(5,3)=2 &(5,4)=1&(5,5)=0&(5,6)=1\\(6,1)=5&(6,2)=4&(6,3)=3 &(6,4)=2&(6,5)=4&(6,6)=0\end{array}\right\}[/tex]

Thus, the sample space Sample space-related when two dice are tossed & the magnitude is:

S = {0,1,2,3,4,5,}

Answer:

A 40%

Step-by-step explanation:

The percentage of the people surveyed that are adults is; A: 40%

We are given;

Sample size of adults and children = 250

From the table, we see that;

Proportion of adults that can swim = 0.34

Proportion of adults that can't swim = 0.06

Thus;

Total proportion of Adults in the survey = 0.34 + 0.06

Total proportion of Adults in the survey = 0.40

Thus, percentage of people surveyed that are adults = 0.40 * 100% = 40%

Answer:

8.1

Step-by-step explanation:

Since we dealing with right triangles, we are going to use pythagoern theorem.

[tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex], where a and b are the two legs and c is the longest side or the slanted side( known as hypotunese.)
