ANSWER

The midpoint is a) (m,n)

EXPLANATION

The point O has coordinate (0,0) and the point A has coordinate (2m,2n)

The x-coordinate of the midpoint is

x =  \frac{0 + 2m}{2}

x =  \frac{2m}{2}

x = m

Also,

y =  \frac{0 + 2n}{2}

y =  \frac{ 2n}{2}

y = n

The answer is A

Maurinko [17]

Answer:

40%.

Step-by-step explanation:

Prob( Rolling a 4) = 12/50

Prob( Rolling a 3) = 8/50

When the combined probabilities contain  an 'OR' we Add the probability values:

Probability of a 3 or a 4  

= 12/50 + 8/50

= 20/50

= 2/5

= 40%.

Jose takes a job that offers a monthly starting salary of $2200 and guarantees him a monthly raise of $105 during his first year
vodka [1.7K]

Answer:

$3355

Step-by-step explanation:

Since the job offers starting salary of $2200 and monthly raise of $105 during his first year of training.

∴ a = 2200 and d = 105

Since the general form of A.P is,

a, a + d, a + 2d, a + 3d, .............a_{n}

Where,  a_{n} is the last term of A.P or his monthly salary at the end of his training and n is the number of terms in a series.

So, the A.P is:

2200, 2200 + 105, 2200 + 2(105) .........a_{n}

2200, 2305, 2410 ............a_{n}

Since there is 12 month in a year therefore, n = 12.

a_{n} = a + (n - 1) d\\

.a_{n} = 2200 + ( 12 - 1) × 105

= 2200 + 11 × 105

= 2200 + 1155

= 3355

∴ .a_{n} = 3355

So the monthly salary of Jose at the end of his training is 3355$.

The correct answer is 5 1/2 because if it weren’t simplified it would be 6/2 which makes the numerator the greatest.

Hi are you able to solve it by using a step called exponential equations?
andriy [413]

Given the equation:

6^{2-3x}=6^{-2x-2}

since both bases are 6, we can equate both exponents to get the following equation:

2-3x=-2x-2

solving for x, we get:

\begin{gathered} 2-3x=-2x-2 \\ \Rightarrow-3x+2x=-2-2=-4 \\ \Rightarrow-x=-4 \\ \Rightarrow x=4 \end{gathered}

therefore, the solution of the equation is x = 4
