Answer:

Your answer is 3,000

Step-by-step explanation:

Since the number next to the thousands place on the right is less than 5 we round down.

Which gives us the answer 3,000

If the number was greater than 5 it would be 4,000

Therefore our answer is 3,000

hope this helps! good luck :D

GREYUIT [131]

Answer:

61.57 ft

Step-by-step explanation:

Look at the picture. You need to find the base value.

so we can sue the cosine formula here.

cos x° = adjacent / hypotaneous

cos 52 ° = adj / 100

adjacent = 100 cos 52°

               =61.57 ft

VMariaS [17]

Answer:

The answer is No Solutions

Write the sum using summation notation, assuming the suggested pattern continues. -10 - 2 + 6 + 14 + ... + 110
Nimfa-mama [501]
This is the sum of the arithmetic sequence:
 10 - 2 + 6 + 14 + ... + 110
where:  a 1 = - 10, d = 8
a n = 110
a n = a 1 + ( n - 1 ) * d
110 = - 10 + ( n - 1 ) * 8
110 = - 10 + 8 n - 8
110 + 10 + 8 = 8 n
128 = 8 n
n = 128 : 8
n = 16
∑ n = n/2 * ( a 1 + a n ) 
∑ 16 = 16/2 * ( -10 + 110 ) = 8 * 100 = 800
Answer:
The sum is 800.

In a factory there are 100100 units of a certain product, 55 of which are defective. We pick three units from the 100 units at r
Nadya [2.5K]

Answer:

There is a 33.67% probability that exactly one of them is defective.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Here, we can have different formats. For example, D-ND-ND is the same as ND-D-ND, that is, the ordering is not important. So we use the combinations formula.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

Desired outcomes

One defective(one from a set of 55) and two non defective(two from a set of 45). So

D = C_{55,1}*C_{45,2} = \frac{55!}{54!1}*\frac{45!}{43!2!} = 55*45*22 = 54450

Total outcomes

Three from a set of 100. So

T = C_{100,3} = \frac{100!}{97!3!} = 161700

What is the probability that exactly one of them is defective

P = \frac{D}{T} = \frac{54450}{161700} = 0.3367

There is a 33.67% probability that exactly one of them is defective.
