How many times can Henry expect to roll a 4 if he rolls a fair number cube 120 times?

Answer:

x^2 - 5x - 6  =  (x - 2)(x - 3).

Step-by-step explanation:

f(x) = x^2 - 5x - 6

We need 2 numbers whose product is - 6 and whose sum is -5. They are   -3 and -2:

The factors are x- 2  and x - 3.

Answer:

x-6

Answer:

(b) Least to greatest numbers are -1.0, [tex]-\frac{1}{4}[/tex] , 0, 0.5, 1.5

(c) -1.0 <  [tex]-\frac{1}{4}[/tex]  < 0 < 0.5 < 1.5

OR

1.5 > 0.5 > 0 >  [tex]-\frac{1}{4}[/tex]  > -1.0

Step-by-step explanation:

P.S - The exact question is -

Given - Kendra collected data for her science project. She surveyed

             people asking them how many hours they sleep during a

             typical night.

             The chart below shows how each person’s response compares

              to 8 hours (which is the answer she  expected most people to say).

Name                Number of Hours                       Compared to Hours

                         (usually slept each night)

Frankie                        8.5                                                    0.5

Mr. Fields                      7                                                      −1.0

Karla                             9.5                                                     1.5

Louis                             8                                                         0

Tiffany                            [tex]7\frac{3}{4}[/tex]                                                       [tex]-\frac{1}{4}[/tex]

To find - (a) Plot and label each of the numbers in the right-most column

                   of the table above on the number line below.

               (b) List the numbers from least to greatest.

                (c) Using your answer from part (b) and inequality symbols,

                     write one statement that shows the relationship  among all

                     of the numbers.

Proof -

(a)

We can see that the numbers in the right-most column are  0.5, -1.0, 1.5, 0, [tex]-\frac{1}{4}[/tex]

We can write [tex]-\frac{1}{4}[/tex] = -0.25

Now,

We have to label them in the number line

The number line is as follows :

(b)

Least to greatest numbers are -1.0, [tex]-\frac{1}{4}[/tex] , 0, 0.5, 1.5

(c)

By using inequality symbol, we get

-1.0 <  [tex]-\frac{1}{4}[/tex]  < 0 < 0.5 < 1.5

OR

1.5 > 0.5 > 0 >  [tex]-\frac{1}{4}[/tex]  > -1.0

Answer:

12 green marbles

Step-by-step explanation:

first we know that there are 39 red and blue marbles, so 3x+10x=39 x=3

since the amount of green marbles is 4x, and we know x=3, x*4=12

Answer:

increase

Step-by-step explanation:

Increase definition: become or make greater in size, amount, intensity, or degree.

Decrease definition: make or become smaller or fewer in size, amount, intensity, or degree.

Answer:

x=128

Step-by-step explanation:

180-52=128

Answer: x= 128 degrees

Step-by-step explanation:

Angle “x” and angle with measure of 52 degrees are a linear pair.

Linear pairs sum to 180.

52+x=180. Subtract 52 from both sides.

X= 128

*OR you can use angles around a point sum to 360 degrees.

52+38+142+x = 360. Combine like terms.

232+x= 360. Subtract 232 from both sides.

X= 128

Answer:

y = 2

Step-by-step explanation:

Given

y = x² + 2x + 3 ← substitute x = - 1

y = (- 1)² + 2(- 1) + 3 = 1 - 2 + 3 = 2

Solution: She has £36 remaining.

To solve this is fairly simple.  First we multiple 72 by .4 to get 40%.  This gives us 28.8.  

We then subtract 28.8 by 72 to get the money she has remaining after she spends 40%.  The answer to this is 43.2

Then she spends 1/6 on makeup.  So we divide 43.2 by 6 and multiply again by 5, which gives us 36.

Answer:

1 ) 140

2) 60

Step-by-step explanation:

1. It touches the y intercept at 140 and 0 in the x axis so 140

NOTE : THE NUMBER THE TOUCHES THE Y INTERCCEPT IS ALWAYS THE ANSWER/ IT GOES DOWN 3 ACROSS 3 SO IT AND U WILL SEE IF IT TOUCHES THE Y INTERCEPT IT WILL BE 140

2. it goes from 140 to 200 just subtract them to get how much she gets

Answer:

a) the new perimeter is 2 times the old perimeter

b) the new area is 4 times the old area

Step-by-step explanation:

b) the doubling of the length and width affects the area formula like this:

old triangle area formula = 1/2bh

new triangle area formula = 1/2(2b)(2h),   you see the 2 x 2 causes the area to be 4 fold

y-yi=m(x-xi)

y-3=1/4(x-4)

y-3=x-4/4

4y-12=x-4

4y+x-12+4=0

4y+x-8=0

so the equation of

the line perpendicular

to

y=1/4-5 through

the point(4,3)

Answer:

The "middle triangle"

50+85+n=180

n+135=180

n=45

The "left side triangle"

x+68+45=180

x=67

The "right-side triangle"

50+74+z=180

124+z=180

z=56

y=180-56

y=124

Answer:

The length of BC is 3.61 units.

Step-by-step explanation:

√13=3.60555128=3.61 (Round off to two places)

According to Pythagoras theorem,

Hypotenuse²=Perpendicular²+Base²

H²=P²+B²

Perpendicular given=3 units

Base given=2 units

H²=3²+2²

H²=9+4

H²=13

H=√13 units

H=3.61 units (approx)
