Answer:

MP= (1,-3.5) or written another way MP= (1, $-\frac{7}{2}$ )

Step-by-step explanation:

Midpoint formula: $MP= (\frac{x_1+x_2}{2}),(\frac{y_1+y_2}{2} )$

$MP= (\frac{-5+7}{2}),(\frac{-2+-5}{2})$ -5+7=2 -2+-5=7

$MP= (\frac{2}{2}),(\frac{-7}{2})$ 2/2=1 -7/2=-3.5

$MP= (1,-3.5)$

2. Mrs. Siebenaller bought a “bus” for $25,000 with a 7% interest rate. Mrs. S. gets a loan to pay off in 5 years. How much inte

PSYCHO15rus [73]

Answer: the correct option is A

Step-by-step explanation:

Cost of the bus is $25000. She took a loan of $25000 to be paid of in 5 years at an interest rate of 7%.

The formula for simple interest is expressed as

I = PRT/100

Where

I = interest

P = principal or initial amount borrowed

T = time in years

R = interest rate in percentage

From the information given,

P = 25000

R = 7%

T = 5 years

Therefore

I = (25000 × 7 × 5)/100 = 875000/100

I = $8750

There are 135 people in a sport centre. 73 people use the gym. 59 people use the swimming pool. 31 people use the track. 19 peop

wlad13 [49]

Answer:

Probability that the person doesn't use any facility = 0.0889

Step-by-step explanation:

Total number of people in a sports center = 135

Number of people using gym 'G' = 73

Number of people using swimming pool 'P' = 59

Number of people using track 'T' = 31

Number of people using gym and pool (G∩P) = 19

Number of people using pool and track (P∩T) = 9

Number of people using gym and track (G∩T) = 16

Number of people using all three facilities (G∩P∩T) = 4

Therefore, from the rule of compound probability,

P(GUPUT) = P(G) + P(P) + P(T) - P(G∩P) - P(G∩T) - P(P∩T) + p(G∩P∩T)

We know probability of an event = $\frac{\text{Favorable event}}{\text{Total outcomes}}$

We will plug in the values of probabilities of each event in the formula.

P(GUPUT) = $\frac{73}{135}+\frac{59}{135}+\frac{31}{135}-\frac{19}{135}-\frac{9}{135}-\frac{16}{135}+\frac{4}{135}$

= $\frac{1}{135}(73+59+31-19-9-16+4)$

= $\frac{123}{135}$

And probability that a person doesn't use any facility = 1 - P(GUPUT)

= 1 - $\frac{123}{135}$

= $\frac{135-123}{135}$

= $\frac{12}{135}$

= $\frac{4}{45}$ ≈ 0.0889
