Of the 960 students writing an examination in a school, 840 are expected to pass. The estimated probability that a randomly chosen student will fail the examination is

Answer:

Since 1/5 is 0.2

and 1/5 × 9 is 9/5

We can do 0.2 × 9

which you should get 1.8

OR you can do 0.2 + 0.2 + 0.2 +0.2 +0.2 + 0.2 + 0.2 + 0.2 + 0.2 (which is 0.2 added 9 times)

Which also results in 1.8

Answer:

she could mabey multiply 9x0.2=1.8

Step-by-step explanation:

it might be 1.8 because if 1/5=0.2 and she needs to find out what 9/5 is so

you need to multiple 9x0.2 but im not sure if im right

Answer:

2/3

Use the rise over run formula and then simplify

Answer:

D

Step-by-step explanation:

Slop formula: m = (y2 - y1)/(x2 - x1)

First coordinate: (-3, -7)

Second coordinate: (9, 1)

m = (1- (-7) ) / (9 - (-3) )

m = (1 + 7) / (9 + 3)

m = (8)/(12)

m = 2/3

Answer:

x= 10

y= 14

Step-by-step explanation:

So right were the 5 is you wanna make that into a triangle to solve for the missing side using 3 as height and 5 as hypotenuse. you get 4 so subtract 4 from 14 to get 10.

100-64=36 sqrt36=6  26-6-6=14

Answer:

its not c i got it wrong on the test

Step-by-step explanation:

Answer:

1/2 or 1/3

Step-by-step explanation:

if you add them across you will get 4/12 which you would simplify and it will give you 1/3 but if you keep the bottem numbers as 8 then add 3 and 1 it will give you 4/8 simplify that's and it gives you 1/2

Answer:

x = 30

y = 5

Step-by-step explanation:

Because the top triangle shows 3 congruent angles, we know it's an equilateral.

Therefore 8y = 40

y = 5

______________

Now we have two sides of the triangle: 40 and 80.

The lower left angle of the whole triangle must be 90 degrees because if the hypotenuse is twice the adjacent side, it must be a 30-60-90 triangle.

So, the larger angle containing angle x must be 90 degrees. And because we know that the adjacent angle (equilateral triangle) is 60 degrees, angle x must be 30.

Answer:

$4 (nearest dollar) ;

$4.4 (nearest dime) ;

$4.41 (nearest penny

Step-by-step explanation:

The actual price of premium gasoline is $4.409 per gallon.

A penny = $0.01 or 1 cent

A dime = $0.1 or 10 cent

Price of premium gasoline to the nearest dollar :

$4.409 is rounded to the nearest unit = $4

Price of premium gasoline to the nearest penny : = $4.409 is rounded to the nearest hundredth = $4.41

Price of premium gasoline to the nearest dime : = $4.409 is rounded to the nearest tenth = $4.4

Answer: k=1 which equals 1k.  

Step-by-step explanation:

k+0=k

k is really 1k

so the real equation is 1k+0=1k because 1k+0 means nothing really it's still 1k.

Answer:

148

Step-by-step explanation:

The shape congruent to given figure is Figure 4.

Option D is correct.

Congruent figures have sides that are the same length and angles that are the same measurement. In other terms, two figures are said to be congruent when they are superimposed upon one another. Even when they are flipped or rotated, they perfectly fit on top of one another.

We have a figure which is similar to parallelogram.

First, figure is seems to be rectangle and do not have same unit measurement which is not Congruent.

Now, the second has more width than given figure.

Now, Third figure is also a rectangle and cannot be congruent.

Now, the fourth figure is similar to given figure.

I am reading this correctly, the width = 1/3 of the length?

If this is the case, and we know that the area is 675, the equation is as follows.

Width x Length = 675 ft2

X = length

1/3 X  x  X =  675 ft2

To solve for X we have to multiply both sides by 3.

X square 2 = 2601 square feet.

Take the square of each side.

X =  225 sqare feet.

Answer:

x ≤ 49 / 12

Step-by-step explanation:

Total cups of flour = 63 /8

Cake = 7/4 cups

Cookies = 3/2 cups per batch

Flour left after baking cake :

63/8 - 7/4

(63 - 14) / 8

49 / 8

Batch of cookies which can be baked, x

Flour left / cups of flour per batch of cookies

x ≤(49 / 8) ÷ (3 / 2)

x ≤ (49 /8) * 2/3

x ≤ 98 / 24

x ≤ 49 / 12

The probability is 1/4

Step-by-step explanation:

So there's 4 possible outcomes. So if you roll the spinner and you can only get one outcome. So it'll be 1/4.

Answer: length of the rectangular firls = 50

and the breadth = x-20m= 50-20m =30m

Step-by-step explanation:

The perimeter of a rectangle is given as  2(l+b)

let the length be represented as x

such that the breadth = x-20m

so our expression for the perimeter of the rectangular firls becomes

Perimeter = 2l+ 2b

160= 2x + 2 ( x-20)

160= 2x+ 2x-40

160+40 =4x

200= 4x

x= 200/4

x= 50

So the length of the rectangular firls = 50

and the breadth = x-20m= 50-20m =30m

Answer:

Length =60m

Breadth= 20m

Step-by-step explanation:

Breadth of the rectangular firls = 20m

Perimeter = 160m

Length = X

Perimeter of a rectangle = 2(L +B)

Where L= Length

           B = Breadth

160 = 2( 20 + X)

160 = 40 +20X

160- 40 =20X

120= 20X

20X = 120

X = 120/20

X = 60

The dimensions are:

Length =60m

Breadth= 20m

20 cookies

Step-by-step explanation:

What we know:

- Mrs. Trainer baked 120 cookies

- 1/6 of the 120 cookies went to her students

To find the number of cookies that Mrs. Trainer gave to her students, multiply 120 by 1/6.

[tex]120*\frac{1}{6}\\= \frac{120}{6} \\[/tex]

Simplify the fraction

[tex]= 20[/tex]
