KIM [24]

Answer:

Step-by-step explanation:

J = (1/3)M + 2 <=== ur expression would be : (1/3)M + 2

A = 2J - 5

if marcella is 63....

J = (1/3 * 63) + 2 A = 2J - 5

J = 63/3 + 2 A = 2(23) - 5

J = 21 + 2 A = 46 - 5

J = 23 <== justin's age A = 41 <=== Aimee's age

A motor vehicle has a maximum efficiency of 39 mpg at a cruising speed of 40 mph. The efficiency drops at a rate of 0.1 mpg/mph

svp [43]

Answer:

38 mpg

Step-by-step explanation:

Initial efficiency = 39 mpg

Initial speed = 40 mph

Final speed = 50 mph

The efficiency drop between 40 mph and 50 mph is given by:

$E_d = 0.1 \frac{mpg}{mph}*\Delta V$

The total efficiency drop from 40 to 50 mph is:

$E_d = 0.1 \frac{mpg}{mph}*(50-40)mph\\E_d = 1\ mpg$

Therefore, the efficiency at 50 mph is:

$E_{50} = E_{40} -E_d\\E_{50} = 39 -1\\E_{50} = 38\ mpg$

Answer:

$P(Green\ and\ Green) = \frac{25}{144}$

Step-by-step explanation:

Given

$Green=5$

$Blue = 7$

Required

$P(Green\ and\ Green)$

This is calculated as:

$P(Green\ and\ Green) = P(Green) * P(Green)$

Since, it is a probability with replacement, we have:

$P(Green\ and\ Green) = \frac{Green}{Total} * \frac{Green}{Total}$

So, we have:

$P(Green\ and\ Green) = \frac{5}{12} * \frac{5}{12}$

$P(Green\ and\ Green) = \frac{25}{144}$
