Answer:

The sample space is S={HHH, TTT, HTT, HHT, TTH, THH, THT, HTH}

Step-by-step explanation:

Given that a coin is flipped three times.

H represents heads, and T represents tails.

we have to find the sample space.

The sample space contains $2^n=2^3=8$ elements.

As three times the coin is flipped.

∴ The possible outcomes i.e the sample space is

S={HHH, TTT, HTT, HHT, TTH, THH, THT, HTH}

The first choice is correct option.

What is the y-intercept of the line that is

DaniilM [7]

Answer:

The y-intercept of the line would be (C) 8

Step-by-step explanation:

The slope of the line with the equation y = -3x - 5 is -3. When figuring out a slope perpendicular to another line you would use the negative reciprocal of the slope which would lead to the slope of the line to be 1/3.

We know it passes through the point (-3,7), substituting x and y, we would then get our new equation, $(7) = \frac{1}{3}( -3) + b$ .

Solve the equation by multiplying -3 with 1/3 and the product would be -1. Add negative one on both sides and you would get 8 = b.

A trampoline has an area of 49pi square feet what's the diameter of the trampoline

Anna007 [38]

Area of a circle is π*r²
sub what we're given
49π= πr²
49π= π*r²
r²= 49π/π
r²=49
r=7
The diameter is twice the radius therefore the diameter is 14 units

She decides to change the length of the top of the top of the trapezoid shaped garden from 32 to 24 ft. Which expression finds t

gulaghasi [49]

Answer:

<h3>The change in the scale factor is $\frac{3}{4}$ ft</h3>

Step-by-step explanation:

Given that Sienna planned a trapezoid-shaped garden.

And She decides to change the length of the top of the trapezoid-shaped garden from 32 ft to 24 ft.

Let Old length of the top be 32 ft

Let New length of the top be 24 ft

$Scale factor =\frac{New length}{old length}$

$Scale factor = \frac{24}{32}$

$=\frac{3}{4}$ ft

<h3>∴ the change in the scale factor is $\frac{3}{4}$ ft</h3>

What is the value of X <br> FSB-ZDR

Dovator [93]

Answer:

x=22

Step-by-step explanation:

Since the two triangles are similar we can set up two ratios...

(sorry if these numbers are wrong the picture isn't very clear)

38:15.2

We can simplify this ratio into...

2.5:1

Now we solve for x

55:x

We divide 55 by 2.5

55/2.5=22

x=22
