8 0

Answer:

Let p be the amount invested at 8%. Then the amount invested at 5% would be 30,000-p. So:

.08p+.05(30,000-p)=2100

.03p+1500=2100

.03p=600

p=20,000

$20,000 was invested at 8%; $10,000 was invested at 5%

Lemur [1.5K]

Answer:

Answer is 28/4 = 7

Step-by-step explanation:

Given

Beth B = 28 problem

B has 4 times more problem than Mery m

Find

Total number of problem Mery m has if Beth has 4 times more problem than Beth

So,

B = 4 x m

m = B/4 = 28/4 = 7

Finally answer (d) is correct which is 28 ÷ 4 = m

A pair of standard dice is rolled find the probability that the sum of the two dice is greater than 12

kogti [31]

Answer:

Probability that the sum of the two dice is greater than 12 is ZERO.

Step-by-step explanation:

Here, when two dices are rolled together, the sample space is given as:

(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6),

(2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6),

(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6),

(4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6)

(5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5,6)

(6, 1), (6, 2), (6, 3), (6, 4),(6,5), (6,6) = Total 36 outcomes

Now, E : Event of getting a sum greater than 12.

So here, number of possible outcomes = 0

So, the probability that the sum of the two dice is greater than 12 = 0/36 = 0

So, it is an IMPOSSIBLE EVENT.
