What is the hypotenuse?<br><br> Legs are 12 and 15
Goshia [24]
Hey there! :)

You have to use the Pythagorean Theorem: a² + b² = c²

a = 12
12² = 12 × 12 = 144

b = 15
15² = 15 × 15 = 225

144 + 225 = 369

√369 = 19.2

The hypotenuse is 19.2

Hope this helps :)

A random sample of adult drivers was obtained where 52% were men and 46% were women. Note that everyone is not classified as a m
VashaNatasha [74]

Answer:

a) P(G | M) = 0.577

b) P(W | G) = 0.523

c) P(M and G') = 0.220

d) P(M or G) = 0.870

e) P(G') = 0.350

Step-by-step explanation:

A random sample of adult drivers was obtained where 52% were men and 46% were women.

P(M) = 0.52

P(W) = 0.46

A survey showed that 65% of the drivers rely on GPS systems.

P(G) = 0.65

30% of the drivers are men and use GPS while 34% of the drivers are women and use GPS.

P(M and G) = 0.30

P(W and G) = 0.34

a) Suppose the person selected is a man. What is the probability that he relies on a GPS system? Your answer should have at least 3 decimal places

P(G | M) = ?

Recall that conditional probability is given by

∵ P(B | A) = P(A and B)/P(A)

For the given case,

P(G | M) = P(M and G)/P(M)

P(G | M) = 0.30/0.52

P(G | M) = 0.577

b) Suppose the person selected relies on a GPS system. What is the probability that the person is a woman? Your answer should have at least 3 decimal places.

P(W | G) = ?

Recall that conditional probability is given by

∵ P(B | A) = P(A and B)/P(A)

For the given case,

P(W | G) = P(W and G)/P(G)

P(W | G) = 0.34/0.65

P(W | G) = 0.523

c) What is the probability that the person is a man and does not rely on a GPS system? Your answer should have at least 3 decimal places.

P(M and G') = ?

Where G' means does not rely on a GPS system

P(M and G') = P(M) - P(M and G)

P(M and G') = 0.52 - 0.30

P(M and G') = 0.220

d) What is the probability that an individual is a man or uses a GPS system? Your answer should have at least 3 decimal places.

P(M or G) = ?

Using the addition rule of probability,

∵ P(A or B) = P(A) + P(B) - P(A and B)

For the given case,

P(M or G) = P(M) + P(G) - P(M and G)

P(M or G) = 0.52 + 0.65 - 0.30

P(M or G) = 0.870

e) What is the probability that an individual does not use a GPS system? Your answer should have at least 3 decimal places.

P(G') = ?

P(G') = 1 - P(G)

P(G') = 1 - 0.65

P(G') = 0.350

Solve for the indicated variable. <br><br> s = p + g/h for g.
Afina-wow [57]

Answer:

g = h(s-p)

Step-by-step explanation:

  1. find the variable of interest — It is in the numerator of one of two terms on the right side of the equation
  2. subtract every term on that side not containing the variable — subtract p to get s-p = g/h
  3. multiply by the inverse of the coefficient of the variable of interest — the coefficient is 1/h, so we multiply by h to get ... h(s-p) = g
  4. rearrange to the desired form. Here, it is probably OK to leave the parentheses and to simply put g on the left

g = h(s -p)
