Which number sentence is not true?
A. | -1 | > 1/2
B. | -1 | = -1
C. | 1/2 | < | -1 |
D. | -1/2 | < | -1 |

Answer:

Step-by-step explanation:

   [tex]\boxed{Mean = \dfrac{Sum \ of \ all \ data}{number \ of data}}[/tex]

              [tex]\sf = \dfrac{234 + 247 + 236+212+248+243+176+195}{8}\\\\= \dfrac{1791}{8}\\\\= 223.875[/tex]

Arrange the numbers in ascending order.

  176 , 195 , 212 , 234 , 236 , 243 , 247, 248  

Number of data is even. So, median will be the average of 234 and 236

Median = average of the middle two terms.

            [tex]\sf = \dfrac{234+236}{2}\\\\ =\dfrac{470}{2}\\\\= 235[/tex]

Mode is the data which is occurring more number of times.

Range = maximum - minimum

           = 248 - 176

            = 72

What is the arrangements formula?

Step-by-step explanation:

Answer:

x = 6, y = 0, m = -1
y = mx + b
0 = -1(6) + b
0 = -6 + b

Answer:

3 is $8 and 14 is about 18%

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

since the annual rate is 2% and you wait 6 months which is half a year

you'd get 1% of 800 so it'd be 8.

The limit of the expression [tex]f(x) = \frac{x^2 - 12}{x^2 - 3}[/tex]a s x approaches 3 is -1/2

The expression is given as:

[tex]f(x) = \frac{x^2 - 12}{x^2 - 3}[/tex]

As the variable x approaches 3, the limit is represented as:

[tex]\lim_{x \to 3} f(x)[/tex]

So, we have:

[tex]\lim_{x \to 3} = \frac{3^2 - 12}{3^2 - 3}[/tex]

Evaluate the exponents

[tex]\lim_{x \to 3} = \frac{-3}{6}[/tex]

Evaluate the quotient

[tex]\lim_{x \to 3} = -\frac{1}{2}[/tex]

Hence, the limit of the expression as x approaches 3 is -1/2

Step-by-step explanation:

Took the final test and this was the correct answer

Answer:

option 1, 2

Step-by-step explanation:

since R is between Q and S

____________________

Q    (3x+6)     R    (5x-2)    S

--------------(12x - 4)-------------

Q                                       S

so

QR + RS = QS

[tex](3x+6) + (5x - 2) = 12x - 4\\(3x + 5x) + (6 - 2) = 12x - 4\\(8x) + (4) = 12x - 4\\8x + 4 - 4 = 12x - 4 -4\\8x = 12x - 8\\8x - 12x = 12x - 12x - 8\\-4x = -8\\\frac{-4x}{-4} = \frac{-8}{-4}[/tex]

Answer:

Answer:

0.16

Step-by-step explanation:

AND = Probability(of 1)*Probability(of 2)

OR = Probability(of 1)+Probability(of 2)

probability of spinning red = 0.2 or 20%

probability of NOT spinning red = 0.8 or 80%

The question says "AND" so 0.2 * 0.8 = 0.16 or 16%

The given sequence is in Arithmetic progression, and we have to find its nth term ~

So, let's get it solved ~

First term of the sequence is :

Common difference is :

Now, if we have to write the 2nd Term with respect to first one, we can write :

similarly ~

Therefore, I similar pattern ~

[tex] \qquad \sf  \dashrightarrow \: nth \: term = a + (n - 1)d[/tex]

[tex] \qquad \sf  \dashrightarrow \: nth \: term = 2 + (n - 1)2[/tex]

[tex] \qquad \sf  \dashrightarrow \: nth \: term = 2(1 + (n - 1))[/tex]

[tex] \qquad \sf  \dashrightarrow \: nth \: term = 2(1 + n - 1)[/tex]

[tex] \qquad \sf  \dashrightarrow \: nth \: term = 2 n [/tex]

Feel free to ask your doubts, if you have any ~

Answer:

Step-by-step explanation:

from the number sequence above, each term except the first is generated by adding 2 to the term immediately preceding it.

the nth term of the sequence is usually designated Tn, and it's usually a function of n

from the number sequence

T1= 2

T2 = 2+2= 4

T3= 4+2= 6

T4= 6+2= 8

therefore, Tn= 2+2×(n-1)

= 2+2n-2

=2-2+2n= 2n

Answer:

( r^-7 )^6 = r^-42 ( in exponential form )

        ( or )

1 / r^42 ( in fractional form )

Step-by-step explanation:

( r^-7 )^6

Formula : -

( a^m )^n = a^( mn )

Here,

a = r

m = - 7

r = 6

mn

= - 7 * 6

= - 42

Hence,

( r^-7 )^6 = r^-42 ( in exponential form )

        ( or )

( r^-7 )^6 = 1 / r^42 ( in fractional form )

Answer:

The median number of shoes for the girls is greater than the median number of shoes for the boys.

The Jasmine take 1 whole 1/6 seconds to rake leaves at the second house.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

We have:

Jasmin rakes leaves at two different houses. it takes her 2 1/3 hours to rake leaves at the first house. it takes her 1/2 of that time to rake leaves at the second house.

From the problem:
[tex]= \rm 2\dfrac{1}{3}\times \dfrac{1}{2}[/tex]

[tex]= \rm \dfrac{7}{3}\times \dfrac{1}{2}[/tex]

[tex]= \rm \dfrac{7}{6}[/tex]

[tex]= \rm 1\dfrac{1}{6}[/tex]

Thus, the Jasmine take 1 whole 1/6 seconds to rake leaves at the second house.

Work Shown:

3 1/2 inches = 3.5 inches

total width = 28*3.5 = 98 inches

The required total width of 28 2 - by -4s laid side by side is 98 inches.

Given,
The width of a 2-by-4 piece of wood is actually 3 1/2 inches. to determine the total width of 28 2-by-4s laid side by side.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

The width of a 2-by-4 piece of wood is actually 3 1/2 inches.
Now, the width of 28 2-by-4 woods laid side by side,
= 28 * 3 1 / 2
= 28 * 7 / 2
= 98

Answer: ∠BAC = 70°

Step-by-step explanation:

    We will use the "Exterior Angle Property" which states that an exterior angle of a triangle is equal to the sum of its two opposite non-adjacent interior angles.

   This means that (6a) + (7a) = 130° which we can solve.

(6a) + (7a) = 130°

13a = 130

a = 10°

    Now that we have the value of a, we can solve for the angle BAC.

7a

7(10)
