Answer:

7/20

Step-by-step explanation:

So first we know that there are a total od 25 students

15+10=25

And the probability of choosing the first girl is 15/25 or 3/5 simpler terms.

Now to be able to choose another girl in a row just multiply the then probability

So we started off with 25, if a girl was choosen, the population would b 24

and with 24, there is a missing girl so instead of 15 it is 14

now 14/24 or 7/12 simplified

multiply the two

7/12*3/5=21/60

Simplified

7/20

Answer: it should be no solution.

Step-by-step explanation:

The graph of the linear equation −6x+9y=−18 , x = -3 and Y = -2.

Linear equations are  equations of the 1st degree. This is a straight line equation. The solutions of linear equations form the values ​​that, when substituted into the unknown values, make the equation true. There is only one solution for one variable. For example, the equation x 2 = 0 has only one solution  x = -2. However, for a linear equation in two variables, the solutions are calculated as the cross coordinates of a point in the Euclidean plane.

Given;

−6x+9y=−18

when x=0

then, -6(0)+9y= -18

                  9y = -18

                    y = -18/9

                    y = -2

put y= 0

          -6x+9(0)= -18

                  -6x = -18

                     x = -18/6

                      x = -3

Answer:

f(x)= -2|x-3|-1

(Hi Jasmine! I just wanted to help you with this question but I might be wrong)

Step-by-step explanation:

f(x) = a|x-h|+k

f(x)= a|x-3|-1

-7 = a |0-3| -1

-7 = a |-3| -1 <-- add to -7

-6 = a |-3|

-6 = 3a

-6/3 = a

-2 = a

---------------------------------- -------------------------------------------------

The equation of the absolute value is f(x)= -2|x-3|-1

Answer:

-2x + 3 – (5 – 6x) = 4x - 2

Step-by-step explanation:

The given expression is :

-2x + 3 – (5 – 6x)

We need to simplify the above expression. First opening the brackets.

-2x + 3 – (5 – 6x) = -2x + 3 – 5 + 6x

Taking like terms together,

= -2x+6x + 3 -5

= 4x - 2

So, the simplified expression is 4x - 2.

Answer:

[tex] \frac{y - ( - 4)}{x - 0} = \frac{3 - ( - 4)}{2 - 0} \\ \frac{y + 4}{x} = \frac{3 + 4}{2} \\ \frac{y + 4}{x} = \frac{7}{2} \\ 2(y + 4) = 7x \\ 7x = 2y + 8 \\ 7x - 2y = 8 \\ 2y = 7x - 8 \\ \boxed{y = \frac{7}{2}x - 4}[/tex]

Answer:

3cm < L < 15cm

Step-by-step explanation:

Given :

Side lengths:

Side 1 = 6cm and side 2 = 9cm

In other to construct a valid triangle, the length of the third side must lie in between.

That is ;

Minimum length must be greater than :

(side 2 - side 1)

9cm - 6cm = 3cm

Maximum length must not exceed :

(side 1 + side 2)

9cm + 6cm = 15cm

Hence, for a valid length for the 3rd side, L:

L > 3cm and L < 15 cm

3cm < L < 15cm

Step-by-step explanation:

here they gave 12 km are reached by 2.5 hours so we. should how much time they took for 1km

12/ 2.5 which is also 150min

12km which is also 12000

12000/150= 80m

it took 80m in 1min so

1hr = 60min

1hr x 80m

60x80

4800

convert it intlo km

4800/1000

4.8km

so it took 4.8 km for 1hour

The time to complete the race is 2.5 hours, then the rate will be equal to 4.8 kilometers per hour.

The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.

They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.

As per the given information in the question,

Total distance = 12 kilometers

Total time taken to complete 12 kilometers = 2.5 hours

Then, the rate in kilometers per hour will be,

= 12/2.5

= 4.8 kilometers per hour.

Answer: Cold length 7+days and medicine taken is 0.24, the box under is 0.76. Cold length 7+days and medicine not taken is 0.69 and the box under is 0.31. It should look like: 0.24 0.69

0.76. 0.31

Step-by-step explanation: the box is vertical, the total is on the bottom and not the side. This means that you would have to add 6 and 19 together to get 25. 6/25 is 0.24 and the box under would be the rest of the number to get to 1.00 (0.76) because the total is on the bottom. If the total was on the side then you would do 6+27=33, then 6/33 = 0.18 and the remaining amount needed to get to 1.00 is 0.82. Furthermore, if the table has the total at the bottom then, the numbers you add are on the bottom and top box. If the table has the total on the side then, the numbers you add are the boxes that are on the left and right. Remember to round to the nearest hundredth. Your welcome.

The two-way column relative frequency table is,

                                          Medicine taken        Medicine not taken  

cold length (≥ 7 days)               0.24                                0.69                

cold length (< 7 days)                10.76                               0.31                

           Total                                1.00                                 1.00                        

"It is a way to display relative frequencies (percentages or ratios), instead of just frequency counts."

For given example,

we have been given a two-way frequency table on whether medicine was taken and cold length.

We need to find the column relative frequency table.

First we find the total of each column.

                                        Medicine taken      Medicine not taken  

cold length (≥ 7 days)                6                                  27                

cold length (< 7 days)                19                                 12                

           Total                               25                                39                  

Now, divide each element of column by its respective total.

                                         Medicine taken           Medicine not taken  

cold length (≥ 7 days)                 6/25                                  27/39                

cold length (< 7 days)                19/25                                 12/39                

           Total                               25/25                                39/39

Therefore, the two-way column relative frequency table would be,

                                           Medicine taken        Medicine not taken  

cold length (≥ 7 days)                 0.24                                0.69                

cold length (< 7 days)                10.76                               0.31                

           Total                                1.00                                 1.00
