Answer:

it is not clear i cant see well the question

Step-by-step explanation:

Answer:Sara hina and Arslan Have RS79.4,RS 72.4 and RS238.2 respectively.

Step-by-step explanation:

Step 1

Let the amount that hina has be x

the amount that sara has be represented as  7+x

and the amount that Arslan have be represented as 3(7+x)

such that the total amount in their wallet which is 390 can be expressed as

x+7+x + 3(7+x)=390

Step 2

Solving

x+7+x +21+3x=390

5x+28=390

5x==390-28

x=362/5=72.4

Hina has RS 72.4

Sara =7+x==72.4+77= RS 79.4

Arslan =3(7+x)=3 x 79.4=RS 238.2

Answer:

Choice C

Step-by-step explanation:

Conditional Probability formula

P(B | A) = [tex]\frac{P(A and B)}{P(A)}[/tex]

P(B | A) = Probability of event B, given probability of event A

P( A and B) = Probability of event A and event B = 0.05

P(A) = Probability of event A = 0.20

P(B | A) = [tex]\frac{0.05}{0.20}[/tex]

P(B | A) = [tex]\frac{1}{4}[/tex] = 0.25

Answer:

8 girsl can sing

8 girls cannot sing

Total number of girls = 16

Step-by-step explanation:

The ratio of girls who csan sing to girls who cant sing is 1:1

Which means the number of girls who can sing and cannot sing are equal .

IF the number of girls who can sing is 8 then the number of girls who cant sing is also 8.

8:8

Dividing both sides by 8 gives

1:1

The total number of girls would be (8+8= )16.

Answer:

348.4 (if that is the number of the question then 52 times 6.7)

63.78 (if 9.52 times 6.7)

Answer:

Step-by-step explanation:

When we are creating a histogram it's best to create a range for the different variables that are available.

So for the sake of covering all the possible ranges from 1 - 22, we should divide it into 5 categories.

0 - 5        

6 - 10  

11 - 15

16 - 20

21 - 25

Now that we have a set of ranges for the different variables, we can find the frequencies.

0 - 5  : 3      

6 - 10 : 2

11 - 15 : 3

16 - 20 : 1

21 - 25 : 3

Since we have this we just add it to the histogram.

It should look like the image attachted below, I hope this helps :)

Answer:

22. 3/8

23. 3/5

24. 0

Step-by-step explanation:

turn the 1 into a fraction for each of the problems.

for 22. it would be 8/8 because also trying to make the denominators the same.

8/8 - 5/8 = 3/8

try 23 and 24 now!

Answer:

B

Step-by-step explanation:

Step-by-step explanation:

The point of intersection occurs when the two graphs have equal values of  x and  y at the same time. There is only one solution, because two straight lines can only intersect once.

[tex]y =4x^2 + 8x + 3 , y = x + 5\\\\4x^2 + 8x + 3 = x +5\\\\4x^2 + 8x + 3 -x -5 = 0\\\\4x^2 +7x -2 =0\\\\4x^2 + 8x -x - 2 = 0\\\\4x(x + 2) -1(x+2) = 0\\\\(4x - 1)(x+2) =0\\\\4x -1 = 0 , x+2 =0\\\\x = \frac{1}{4}, -2[/tex]

[tex]x_1 = \frac{1}{4}, x_2 =-2[/tex]

[tex]y_1 = 4x^2 + 8x + 3 \\\\x_1 = \frac{1}{4}\\\\y_1 = 4(\frac{1}{4})^2 + 8(\frac{1}{4}) + 3 = \frac{1}{4} + 2 + 3 = \frac{1}{4} +5 = \frac{21}{4}\\\\y_2 = x+ 5\\x_2 = -2\\y_2 = -2 + 5 =3[/tex]

Answer :

[tex](x_1, y_1) = (\frac{1}{4} , \frac{21}{4})\\\\(x_2,y_2) = (-2, 3)[/tex]

Answer:

(- 2, 3 ) and ([tex]\frac{1}{4}[/tex], [tex]\frac{21}{4}[/tex] )

Step-by-step explanation:

Given the 2 equations

y = 4x² + 8x + 3 → (1)

y = x + 5 → (2)

Substitute y = 4x² + 8x + 3 into (2)

4x² + 8x + 3 = x + 5 ( subtract x + 5 from both sides )

4x² + 7x - 2 = 0 ← in standard form

(x + 2)(4x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

4x - 1 = 0 ⇒ 4x = 1 ⇒ x = [tex]\frac{1}{4}[/tex]

Substitute these values into (2) for corresponding values of y

x = - 2 : y = - 2 + 5 = 3 ⇒ (- 2, 3 )

x = [tex]\frac{1}{4}[/tex] : y = [tex]\frac{1}{4}[/tex] + 5 = [tex]\frac{21}{4}[/tex] ⇒ ([tex]\frac{1}{4}[/tex], [tex]\frac{21}{4}[/tex] )

Answer:

1 yard by 9 yards

2 yards by 8 yards

3 yards by 7 yards

4 yards by 6 yards

Step-by-step explanation:

the perimeter of the rectangular yard needs to be 20 yards

Perimeter of a rectangle = 2 x ( length + width)

20 = 2 x ( length + width)

( length + width) = 20 /2

( length + width) = 10

The sum of the length and width should equal 10

Possible dimensions that would equal 10 are :

1 yard by 9 yards

2 yards by 8 yards

3 yards by 7 yards

4 yards by 6 yards

Answer:

47 degrees

Step-by-step explanation:

This is a parallel line, and this sort of angle is known as an alternate angle, which is a z shaped angle (can be a Z either way). Alternate angles are equal, therefore x=47 degrees too. Hope this helps :)

Answer:

a.) Total pages Lamar have to read the first day to meet his  goal = 300

     Total pages left to read after 3 days = 75

b.) Total pages he need to read on day 8 = 4.6875

Step-by-step explanation:

The exact question is as follows :

Given - Lamar has a list of 600 pages to read to finish his book for his upcoming book report. He sets a goal to read half of the pages left in his book each day.

To find -

a)  How many pages will Lamar have to read the first day to meet his  goal?  

    How many will he have left to read after 3 days?

b)  How many pages will he need to read on day 8?

Solution -

Given that,

Total number of pages = 600

Now,

In Day 1 ,

He will finish half of the pages

So, he finished pages = [tex]\frac{1}{2} (600)[/tex] = 300

i.e.

In Day 1 , he Finished 300 pages.

So,

At the end of Day 1, total pages left = 600 - 300 = 300

so,

Total pages Lamar have to read the first day to meet his  goal = 300

Now,

For day 2 ,

Total pages = 300

He will finish half of the pages

So, he finished pages = [tex]\frac{1}{2} (300)[/tex] = 150

i.e.

In Day 2 , he Finished 150 pages.

So,

At the end of Day 2, total pages left = 300 - 150 = 150

Now,

For day 3 ,

Total pages = 150

He will finish half of the pages

So, he finished pages = [tex]\frac{1}{2} (150)[/tex] = 75

i.e.

In Day 3 , he Finished 75 pages.

So,

At the end of Day 3, total pages left = 150 - 75 = 75

So,

Total pages left to read after 3 days = 75

Now,

For day 4 ,

Total pages = 75

He will finish half of the pages

So, he finished pages = [tex]\frac{1}{2} (75)[/tex] = 37.5

i.e.

In Day 4 , he Finished 37.5 pages.

So,

At the end of Day 4, total pages left = 75 - 37.5 = 37.5

Now,

For day 5 ,

Total pages = 37.5

He will finish half of the pages

So, he finished pages = [tex]\frac{1}{2} (37.5)[/tex] = 18.75

i.e.

In Day 5 , he Finished 18.75 pages.

So,

At the end of Day 5, total pages left = 37.5 - 18.75 = 18.75

Now,

For day 6 ,

Total pages = 18.75

He will finish half of the pages

So, he finished pages = [tex]\frac{1}{2} (18.75)[/tex] = 9.375

i.e.

In Day 6 , he Finished 9.375 pages.

So,

At the end of Day 6, total pages left = 18.75 - 9.375 = 9.375

Now,

For day 7 ,

Total pages = 9.375

He will finish half of the pages

So, he finished pages = [tex]\frac{1}{2} (9.375)[/tex] = 4.6875

i.e.

In Day 7 , he Finished 4.6875 pages.

So,

At the end of Day 7, total pages left = 9.375 - 4.6875 = 4.6875

So,

At the starting of Day 8,

Total pages = 4.6875

So,

Total pages he need to read on day 8 = 4.6875

Answer:

222 cm

Step-by-step explanation:

To find the area of the square we multiply length and height.

15x12 = 180

For the triangular part of the trapezoid we multiply height by width and divide by 2.

12x7 = 84 / 2 = 42

Add the two sums and we get 222 cm.

180 + 42 = 222
