Answer:

B) 3/4

Step-by-step explanation:

The conditional probability of B given A (B|A) is P(A ∩ B) / P(A), when P(A) > 0 (Probability of the intersection of A and B over the Probability of A).

in our case, P(A ∩ B is the amount of people who can snowboard and surf, which according to the picture is 36

P(A) is the amount of people who can snowboard, which from the picture is 48

This means our conditional probability is 36/48, which when simplified is 3/4.

Solve for x in each of the equations or inequalities below, and name the property and/or properties used:

nordsb [41]

Answer

a) 3/4 x = 9

x = $\dfrac{9\times 4}{3}$

x = 12

b) 10+ 3x = 5x

2 x = 10

x = 5

c) a + x = b

x = b - a

d) c x = d

x = $\dfrac{d}{c}$

e) $\dfrac{1}{2} x - g < m$

$\dfrac{1}{2} x< m + g$

x < 2( m + g)

f) q + 5 x = 7 x - r

q + r = 2 x

$x = \dfrac{q + r}{2}$

You are paying off a student loan in monthly installments. After

dem82 [27]

Answer:

The loan will be paid after 39 monthly installments.

Step-by-step explanation:

Since I am paying off a student loan in monthly installments, and after the 4th payment the remaining balance is $ 13,900, while after the 5th payment my remaining balance is $ 13,500, to determine the amount of payments in which the loan was agreed I must perform the following calculation:

13900 - 13500 = 400

400 x 5 = 2000

2000 + 13500 = 15500

15500/400 = 38.75

Thus, the loan will be paid after 39 monthly installments.

today's local newspaper lists 20 stocks of local interest. of those stocks ten increased five decreased and five remained unchan

coldgirl [10]

Answer:

P(x=2) = 0.2368

Step-by-step explanation:

given data

stocks of local interest N = 20

stocks increased K = 10

stocks decreased = 5

remained unchanged = 5

solution

we take here no of stock that are increased randomly n = 2

so here Hypergeometric random variable can take integer value

{max(0, n+k - N ), min(n,K) } = {0,2}

so here

P(x=2)

P(x=k) = $\frac{(^K_k)\times (^{N-K}_{n-k}) }{(^N_n)}$ .......................1

P(x=2 ) = $\frac{(^{10}_2)\times (^{20-10}_{2-2}) }{(^{20}_2)}$

solve it we get

P(x=2 ) = 0.236842

now we use excel function as

HYPGEOM.DIST (k,n,N.cumulative) .....................2

so it will be

HYPGEOM.DIST (2,2,10,,false)

we get

HYPGEOM.DIST (2,2,10,,false) = 0.236842

P(x=2) = 0.2368
