Answer:

$MP= (5,4)$

Step-by-step explanation:

$MP= (\frac{x_1+x_2}{2} )(\frac{y_1+y_2}{2} )$

$MP= (\frac{2+8}{2} )(\frac{8+0}{2} )$ 2+8=10 8+0=8

$MP= (\frac{10}{2} )(\frac{8}{2})$ 10/2=5 8/2=4

$MP= (5,4)$

Assume that in a particular military exercise involving two units, Red and Blue, thereis a 60 % chance that the Red unit will su

Marysya12 [62]

Answer: a) There are 42% chances that both units will meet their objectives.

b) There are 88% chances that one or the other but not both of the units will be successful.

Step-by-step explanation:

Since we have given that

Probability that the Red unit will successfully meet its objectives = 60% = P(R)

Probability that Blue unit will successfully meet its objectives = 70% = P(B)

Probability that only Red unit will be successful = P(only Red) = 18%

As we know that

$P(only\ red)=P(R)-P(R\cap B)\\\\0.18=0.60-P(R\cap B)\\\\0.18-0.60=-P(R\cap B)\\\\-0.42=-P(R\cap B)\\\\P(R\cap B)=42\%$

Hence, there are 42% chances that both units will meet their objectives.

the probability that one or the other but not both of the units will be successful is given by

$P(R\cup B)=P(R)+P(B)-P(R\cap B)\\\\P(R\cup B)=0.60+0.70-0.42\\\\P(R\cup B)=0.88\\\\P(R\cup B)=88\%$

Hence, there are 88% chances that one or the other but not both of the units will be successful.

Rob and Amy each improved their yards by planting rose bushes and shrubs. They bought their supplies from the same store. Rob sp

Lemur [1.5K]

Answer:

The correct answer is that a rose bush costs $10 and a shrub costs $4

Step-by-step explanation:

To solve this, start by writing equations for what each spent. Use x for the cost of a rose bush and y for the cost of a shrub. Below would be the equations for each.

Rob: 8x + 5y = 100

Amy: 8x + 8y = 112

Now to find the cost, we multiply Rob's equation by -1 and add them together. This will get x to cancel and allow us to solve for y.

-8x - 5y = -100

8x + 8y = 112

------------------

3y = 12

y = 4

So we know the cost of a shrub is $4. Now we can plug that in to either of the original equations and solve for the rose bush cost.

8x + 5y = 100

8x + 5(4) = 100

8x + 20 = 100

8x = 80

x = 10

Which means that a rose bush costs $10.
