HHH

HHT

HTH

HTT

THH

THT

TTH

TTT

There are a total of 8 possible outcomes.

1 outcome is all heads.

1 outcome is all tails.

6 outcomes have at least one heads and 1 tails

p(at least 1 heads and at least 1 tails) = 6/8 = 3/4 = 75%

Answer:

36 units

Step-by-step explanation:

The short leg is 9 units and the long one is 12 units.

Use pythagorean theorem to find the hypotenuse, a² + b² = c²

Plug in the numbers: 9² + 12² = c²

81 + 144 = c²

225 = c²

√225 = c

15 = c

Find perimeter by adding all 3 sides: 9 + 12 + 15 = 36 units.

Answer:

66

Step-by-step explanation:

Answer:

Answer will be 36

Step-by-step explanation:

11*11=4 -> (1+1)*(1+1)=4, 22*22=16 -> (2+2)*(2+2)=16. Hence, 33*33 -> (3+3)*(3+3)=36. Add the digits of 11 that will be 2. hope this helps you :)

Answer:

A is a solution because it is in the shaded area.

Step-by-step explanation:

Answer: 2b = 3g

Step-by-step explanation:

This is quite basic to solve, below is a Step by step explanation:

from the given question we have that;

       i.e  b = 1500 gallons per minute

          g = 1000 gallons per minute.

Our questions tells us to write the equation which  relates the flow of water from the blue hydrant, b, to the flow from the green hydrant, g.

ANS:

Since flow from blue  hydrant b = 1500 gallons per minute, we have that

b = 3 * 500

b = 3 * 1000/2 g

b = 3/2 g

equation  gives 2b = 2g

Answer:

52 tickets cost $10 and 18 tickets cost $12

Step-by-step explanation:

10x+12y=804. (1)

x+y=70. (2)

From (2)

x=70-y

Substitute x=70-y into (1)

10x+12y=804

10(70-y)+12y=804

700-10y+12y=804

700+2y=804

2y=804-700

2y=104

y=104/2

y=52

Recall

x+y=70

x+52=70

x=70-52

x=18

52 tickets cost $10 and 18 tickets cost $12

By solving a system of equations we will see that the correct option is A.

First, let's define the variables:

First, we know that 70 tickets were sold, so:

x + y = 70

And we know that they reached $804, then we have:

x*$10 + y*$12 = $804

Then our system is:

x + y = 70

x*$10 + y*$12 = $804

To solve this, we first need to isolate one of the variables in one of the equations, I will isolate x on the first equation:

x = 70 - y

Now we can replace that in the other equation to get:

(70 - y)*$10 + y*$12 = $804

$700 - y*$10 + y*$12 = $804

$700 + y*$2 = $804

y*$2 = $804 - $700 = $104

y = $104/$2 = 52

So, 52 $12 tickets were sold, then the other 18 tickets were $12, so the correct option is A.

Complete Question:

In the triangles, TR= GE and SR=FE. If GF= 3.2 ft, which is a possible measure of TS?

Answer:

3.2ft

Step-by-step Explanation:

From the given information of the question, we can draft out the diagram of the triangles being depicted here. See attached picture showing triangles RST and EFG.

Since we are told that TR= GE, and SR = FE, it means both triangles are isosceles triangle a having 2 equal sides, and triangles RST and EFG are similar.

Also, given that the measure of the 3rd side (GF) of triangle EFG is 3.2ft, therefore, TS = 3.2ft

Step-by-step explanation:

Answer: 2:14, 12:6, and 2:1

Step-by-step explanation:

2:1 and 12:6 are equal because you can multiply the 2 and 1 in 2:1 by 6 to get to 12:6.

But 2:14 is not equal to the ratio 2:1, because you can't multiply 2 and 1 to any one number to equal the ratio 2:14.

Answer:

2 : 5

Step-by-step explanation:

700 g : 1.75 kg

Since ratio should be between same units, so we'll convert either g into kg or kg into g. For convenience, kg will be converted to g

700 g : 1.75 kg × 1000

700 g : 1750 g

Question:

The nth term of a sequence is [tex]\frac{3n^2}{2}[/tex] . Find the fifth term of the sequence

Answer:

The 5th term of the sequence is 37.5

Step-by-step explanation:

Given

[tex]nth\ term = \frac{3n^2}{2}[/tex]

Required

Find the 5th term

To find the 5th term, we simply substitute 5 for n in the above expression.

This gives

[tex]5th\ term = \frac{3 * 5^2}{2}[/tex]

[tex]5th\ term = \frac{3 * 5 * 5}{2}[/tex]

[tex]5th\ term = \frac{75}{2}[/tex]

[tex]5th\ term = 37.5[/tex]

Hence, the 5th term of the sequence is 37.5

Answer:

Please check the explanation part for more details.

Step-by-step explanation:

1. Solve [tex]7y - 6= 2y + 8[/tex]

Send all components contain [tex]y[/tex] to the left, the other components to the right:

<=> [tex]7y - 6 = 2y + 8[/tex]

(sign of  [tex]2y[/tex] is changed from negative to positive, sign of [tex]6[/tex] is changed from negative to positive)

<=> [tex]5y = 14[/tex]

Divide both sides of equation by [tex]5[/tex]:

<=> [tex]y = \frac{14}{5}[/tex]

2. Show that  [tex]\frac{7}{8} - \frac{5}{6} =\frac{1}{24}[/tex]

First, we prove that [tex]24[/tex] is least common multiple(LCM) of the denominators of [tex]2[/tex] components on the left side ([tex]8[/tex] and [tex]6[/tex]).

[tex]8 = 2^{3}[/tex]

6 = [tex]2[/tex] x [tex]3[/tex]

=> LCM = [tex]2^{3}[/tex] x [tex]3[/tex] = [tex]8[/tex] x [tex]3[/tex] = [tex]24[/tex]

Multiply the first component [tex]\frac{7}{8}[/tex] by a factor which is equal to the quotient of LCM and denominator: [tex]\frac{24}{8} = 3[/tex]

=> [tex]\frac{7}{8} = \frac{7*3}{8*3} = \frac{21}{24}[/tex]

Multiply the second component [tex]\frac{5}{6}[/tex] by a factor which is equal to the quotient of LCM and denominator: [tex]\frac{24}{6} = 4[/tex]

=>[tex]\frac{5}{6} = \frac{5*4}{6*4} = \frac{20}{24}[/tex]

=>[tex]\frac{7}{8} -\frac{5}{6} = \frac{21}{24} - \frac{20}{24} = \frac{1}{24}[/tex]

3. Show that [tex]\frac{5}{8} / \frac{7}{12} = \frac{11}{14}[/tex]

[tex]\frac{5}{8} / \frac{7}{12} =[/tex] [tex]\frac{5}{8} * \frac{12}{7} =[/tex] [tex]\frac{60}{56} =\frac{60/4}{56/4} = \frac{15}{14} = 1\frac{1}{14}[/tex]

4. [tex]\frac{v4*v7}{vt} = \frac{v}{v} * \frac{v*4*7}{t} = \frac{v*28}{t}[/tex]

y=-25.3x+51603.5

now, lets use computer:

Using the line of best-fit, it is found that:

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

The line of best-fit is given by:

[tex]y = bx + a[/tex]

[tex]b = \frac{\sum (x - \overline{x})(y - \overline{y})}{\sum (x - \overline{x})^2}[/tex]

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

The means are given by:

[tex]\overline{x} = \frac{0 + 1 + 2 + 3 + 4 + 5}{6} = 2.5[/tex]

[tex]\overline{y} = \frac{1015 + 960 + 950 + 902 + 929 + 866}{6} = 937[/tex]

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

The sums are:

[tex]\sum (x - \overline{x}) = (0 - 2.5) + (1 - 2.5) + ... + (5 - 2.5)[/tex]

[tex]\sum (y - \overline{y}) = (1015 - 937) + ... + (866 - 937)[/tex]

Using a calculator:

[tex]\sum (x - \overline{x})(y - \overline{y}) = -443[/tex]

[tex]\sum (x - \overline{x})^2 = 17.5[/tex]

Thus, the slope is:

[tex]b = -\frac{443}{17.5} = -25.31[/tex]

And

[tex]y = -25.31x + a[/tex]

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

Using the means to find a:

[tex]y = -25.31x + a[/tex]

[tex]937 = -25.31(2.5) + a[/tex]

[tex]a = 1000[/tex]

Thus, the linear regression model is:

[tex]y = -25.31x + 1000[/tex]

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

The number of cases would reach 543 in x years after 2008, and x is found when y = 543. Thus:

[tex]y = -25.31x + 1000[/tex]

[tex]543 = -25.31x + 1000[/tex]

[tex]25.31x = 1000 - 543[/tex]

[tex]x = \frac{1000 - 543}{25.31}[/tex]

[tex]x = 18.1[/tex]

2008 + 18 = 2026

The estimate is that the number of cases would reach 543 in the year of 2026.

Answer:

20 feet

Step-by-step explanation:

Since the term -(x-7)^2 is negative, the largest height that the ball can reach is when this term is 0. 0+20=20, meaning that the highest the ball can go is 20 feet. Hope this helps!

Answer:  20 feet

Step-by-step explanation:

The vertex form of a quadratic equation is: y = a(x - h)² + k

where (h, k) is the vertex

h is the axis of symmetry (time at which maximum height is reached)

k is the maximum height

Given: y = -(x - 7)² + 20

--> h = 7, k = 20

therefore, the maximum height of the ball is 20

Answer:

Step-by-step explanation:

The order from least to greatest is 12,14,16,18,19,22,122.

The middle number is 18 because there is 3 numbers next to 18 on the right which is 19,22,122 and 3 numbers on the left which is 12,14,16. A median would be easier to find if there is an odd amount of numbers.

A word that describes the slope of the line is negative. The correct answer is option B.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data. It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

For this case the first thing you should know is that we have an equation of the form:

y = mx + b

Where,

m: The slope of the line

b: Cutting point with the vertical axis.

For this case, we observe that the values of y decrease when the values of x increase. Therefore, the function decreases.

This means that it is true that:

m < 0

Therefore, the slope of the line is negative.
