Answer: 1/4

Step-by-step explanation: 1/2 chance it shows heads if you do it once so: 1/2 times 1/2

Answer:

[tex]$\frac{1}{4}[/tex]

Step-by-step explanation:

Each time you a flip a coin, there is a [tex]\frac{1}{2}[/tex] chance it lands on heads. Therefore, after flipping a coin twice, the probability that it lands on heads both times is:

[tex]\frac{1}{2}\cdot \frac{1}{2}=\boxed{\frac{1}{4}}[/tex]

Answer:

y = 4x - 2

Step-by-step explanation:

linear equation - y = mx + b

where m = slope and b = y intercept

The y intercept is the y value of the coordinate where x = 0

Looking at the table, we notice that when x = 0, y = -2

Which means that the y  intercept ( b ) = -2

Slope = change in y over change in x

As y goes up 4 x goes up 1

Thus, slope ( m ) =  4

Now we plug in the identified slope and y intercept into " y = mx + b "

we get that the equation is y = 4x - 2

Answer:

Answer is 36.

You can simply get this by writing and expression for it

25/100 x w=9

25w/100=9

w= 9x100/25

w=36.

Answer:

36

Step-by-step explanation:

9/w=25/100

cross multiplication:

9*100=25w

900=25w

900=25w / 25

36=w

Answer:

144 - 36pi

Step-by-step explanation:

1) Since the side lengths of the square are 12 units, the midpoints divide each side into two 6 unit lengths.

2) Those 6 unit lengths are radii of a quarter of a circle.

3) We can use the equation pi × r^2 to calculate the area of the four quarter circles.

4) pi × 6^2

5) 36pi

6) The area of the original square is 12 × 12, which is 144.

7) 144 - 36pi is your answer.

Answer:

The probability that the sampled fraction of voters favoring the bond issue will not differ from the true fraction by more than 0.08 is 0.7698

Step-by-step explanation:

Given  

n = 64

p = 0.20

X/n -p < 0.06

x-np <0.06n

x-np <0.06 * 64  

x-np <3.84

Z score  

= (x-np)/sqrt (np(1-p))

= -3.84/ sqrt (64*0.20*0.80)

= -1.20

P (x/n-p<0.06) = P(-1.2<z<1.20) = 1-2*0.1151 = 0.7698

Step-by-step explanation:

rhombus is a special parallogram.

.

1.angles on rhombus are not equal and for square angles are equal that's why rhombus cant be a square

2. square is a special rhombus

hope u understand

Answer:

no

Step-by-step explanation:

all rhombus are not square.

rhombus has a special condition.(THE DIAGNOLS ARE ALWAYS PERPENDICULAR TO EACH OTHER)

square is a special case of rhombus(IT HAS ITS DIAGONAL PERPENDICULAR TO EACH OTHER AND ALL SIDES ARE EQUAL)

Answer:

B

Step-by-step explanation:

So, this is a inequality.

The inequality is 2x+2 >= 10

Lets completly ignore the graphs for the moment, and just solve this inequawlity as we would like a normal equation.

So first, subtract 2 from both sides:

2x+2>=10

=

2x>=8

Now, divide by 2 to get x alone:

2x>=8

=

x>=4

So, we now know that x is greater than or equal to 4.

In a normal inequality, we would have to remember the following:

When it is greater than/less than or equal to the dot that marks the inequalities value is filled in.

When it is greater than/less than the dot that marks the inequalities value is open, kind of like a "o".

Also, recall that the dark black line that goes either left or right of the dot also varies:

If x is less than the dot that marks the inequalities value, then the dark black line with go left.

If x is greater than the dot that marks the inequalities value, then the dark black lne will go right.

So for our x>=4, since there is a equals sign, its a filled in dot.

So four our x>=4, since there is a greater than sign, the dakr black lines goes to the right.

Now, lets look at the graphs

There is only one that has the filled in dot on 4, and a black line that goes to the right. Thats B

So B is your answer!

Hope this helps! :)

Answer:

B

Step-by-step explanation:

In order to graph we must first isolate the variable.

We can do this by using inverse operations

2x + 2 ≥ 10

To get rid of the + 2 we subtract 2 because the expression is adding 2 and the inverse of addition is subtraction. But remember whatever we do to one side we have to do to the other so we subtract 2 from each side

2 - 2 cancels out

10 - 2 = 8

we now have 2x ≥ 8

Now we want to get rid of the 2 on "2x". 2x is the same as 2 times x and the inverse of multiplication is division, so we divide each side by 2

2x / 2 = x

8 / 2 = 4

we're left with x ≥ 4

To graph we place a point on "4" and fill in the point ( when the inequality sign is ≤ or ≥ we fill in the point )

When the inequality sign is facing the variable ( x ) the line will be going in the direction of right.

Hence, the answer is B

Hello answer: 1 1/3

work: 1/3 × 4 = 1 1/3

equation: 1/3 × 4 = 1 1/3

Answer:

see explanation

Step-by-step explanation:

(a)

[tex]\frac{1}{3}[/tex] can → 1 cake

Number of thirds in 1 can = 3, then

Number of thirds in 4 cans = 3 × 4 = 12

Thus 12 cakes can be frosted with 4 cans

(b)

number of cakes = 4 ÷ [tex]\frac{1}{3}[/tex] = 4 × [tex]\frac{3}{1}[/tex] = 12

Answer:

The scale factor is 1/2

Step-by-step explanation:

Given

[tex]\triangle DE F[/tex] and [tex]\triangle ABC[/tex]

Required

The scale factor from [tex]\triangle DE F[/tex] to [tex]\triangle ABC[/tex]

Take a corresponding side in both triangles.

We have:

[tex]DE= 20[/tex]     [tex]AB = 10[/tex]

The scale factor from [tex]\triangle DE F[/tex] to [tex]\triangle ABC[/tex] is:

[tex]k =\frac{AB}{DE}[/tex]

[tex]k =\frac{10}{20}[/tex]

[tex]k =\frac{1}{2}[/tex]

D)32/40

Hope it helps you

Answer:

[tex]\frac{24}{40}[/tex]

Step-by-step explanation:

Sin = [tex]\frac{opposite}{hypotenuse}[/tex] (relative to the angle asked for)

The opposite of Angle Z is 24

The hypotenuse no matter what would always be 40; therefore,

Sin(Z) = [tex]\frac{24}{40}[/tex]

Answer:

r = 1 feet

Step-by-step explanation:

Given that,

The surface area of the sphere, A = 4π feet²

We need to find the radius of the sphere.

The formula for the surface area of the sphere is given by :

[tex]A=4\pi r^2[/tex]

Where

r is the radius of the sphere

Put all the values,

[tex]4\pi = 4\pi \times r^2\\\\r=1[/tex]

So, the radius of the sphere is equal to 1 feet.
