Answer:sedan can hold 3 people and a minivan can hold 9 people.

Step-by-step explanation:

Suppose the number of passengers each sedan can carry is A and the number of passengers each minivan can carry is B

So 3A + 2B = 21 and 3A + 3B = 27

If we subtract the equations we can solve for B

3A + 3B = 27

-3A - 2B = 21

___________

B = 6

Now we know Each minivan can hold 6 passengers and we can solve for A.

3A + 3B = 27

3A + 3(6) = 27

3A + 18 = 27

- 18. -18

__________

3A = 9

A =3

You can check this by solving the other equation.

3A + 2B = 21

3(3) + 2(6) = 21

9 + 12 = 21

Hope that helps

The probability of event A is 0. 48, the probability of event A and B is 0. 21, and the probability of events A or B is 0. 89. W

Mice21 [21]

Probabilities are used to determine the chances of an event

The probability of event B is 0.62

The probabilities are given as:

$\mathbf{P(A) = 0.48}$

$\mathbf{P(A\ and\ B) = 0.21}$

$\mathbf{P(A\ or\ B) = 0.89}$

To calculate the probability of event B, we make use of the following formula

$\mathbf{P(A\ and\ B) = P(A) + P(B) - P(A\ or\ B)}$

So, we have:

$\mathbf{0.21 = 0.48 + P(B) - 0.89}$

Collect like terms

$\mathbf{P(B)= -0.48 +0.21 + 0.89}$

$\mathbf{P(B)= 0.62}$

Hence, the probability of event B is 0.62

A retail shop is replacing their flooring with laminate wood. The floor plan is shown below. Determine the total square feet of

Phantasy [73]

<h3>Answer: 1075 square feet</h3>

===========================================================

Explanation:

As shown in the diagram below, I've drawn a blue horizontal line to split the figure into two rectangles (smaller one up top, larger down below).

The smaller rectangle up top is 25 ft by 8 ft, giving an area of 25*8 = 200 sq ft.

The larger rectangle down below is 35 ft by 25 ft so we have an area of 35*25 = 875 sq ft.

The total area is 200+875 = 1075 square feet

Notes:

We can write "square feet" as "sq ft" or as "ft^2" without quotes.
The portion "5 ft", in the upper left corner, is never used.
