Answer:

Step-by-step explanation:

LCM = 96

12 = 4×3

32 = 4 × 8

then GCF = 4

LCM - GCF = 96 - 4 = 92

What is the sum of 1 and opposite of 12

likoan [24]

The opposite of 12 is -12 . To add negative numbers to positive numbers count backwards, as if you were subtracting. We have the problem: 1+ (-12). This can be read as “one plus negative twelve.” This can also be read as 12-1 which is 11 so the answer is 11.

The random variable X~(30,2^2) Find p(X<33) Find p(X>26)

Ostrovityanka [42]

Answer:

i) P(X<33) = 0.9232

ii) P(X>26) = 0.001

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 30

Given that the standard deviation of the Population = 4

Let 'X' be the Normal distribution

Step(ii):-

Given that the random variable X = 33

$Z = \frac{x-mean}{S.D}$

$Z = \frac{33-30}{2} = 1.5$ >0

P(X<33) = P( Z<1.5)

= 1- P(Z>1.5)

= 1 - ( 0.5 - A(1.5))

= 0.5 + 0.4232

P(X<33) = 0.9232

Step(iii) :-

Given that the random variable X = 26

$Z = \frac{x-mean}{S.D}$

$Z = \frac{33-26}{2} = 3.5$ >0

P(X>26) = P( Z>3.5)

= 0.5 - A(3.5)

= 0.5 - 0.4990

= 0.001

P(X>26) = 0.001

suppose that the local sales tax rate is 6.25% and youpurchased a used carr for 16,800. what is the car's total cost

Gwar [14]

Total= Car Cost + (Car Cost * Tax %)

Total= $16,800 + ($16,800 * 6.25%)

convert % to decimal form; divide % by 100

Total= $16,800 + ($16,800 * 0.0625)

multiply inside parentheses

Total= $16,800 + $1,050

Total= $17,850

ANSWER: The total cost for the used car with tax is $17,850.

Hope this helps! :)

Im stuck .... What is the solution for the equation 2(3x−7)=−4(x+5)+3? plss show work

Ipatiy [6.2K]

Answer:

$2(3x - 7) = - 4(x + 5) + 3 \\ 6x - 14 = - 4x - 20 + 3 \\ 6x + 4x = - 20 + 3 + 14 \\ 10x = - 3 \\ \\ x = \frac{ - 3}{10} \\ \\ x = - 0.3$

I hope I helped you^_^
