Answer:

The answer is 61.

Step-by-step explanation:

Let, the numbers are: x, (x+2), (x+4)

Now, x+x+2+x+4 = 183

3x + 6 = 183

3x = 177

x = 59

So, second number would be: (x+2) = (59+2) = 61

Lim wrote several pairs of values that he thought were equivalent. Which of his equations is correct?

Annette [7]

Answer:

I believe the correct answer would be A: 3/5 = 60

Step-by-step explanation:

Firstly, the second option is wrong because 0.06 would be 6 hundredths, so that is wrong, the third option would be incorrect because 0.002 would equal 2 thousandths so that is also wrong, and the fourth option would be 25% instead of 75%, so your answer should be A.

A vehicle factory manufactures cars. The unit cost (the cost in dollars to make each car) depends on the number of cars made. If

Nataly [62]

Answer:

The function is missing in the question. The function is $C(x) = 0.8x^2 -544x +97410$

The answer is 4930

Step-by-step explanation:

Unit cost of a car is given as

$C(x) = 0.8x^2 -544x +97410$

Cost will be minimum when

x = -(-544)/ 2 x 0.8

= 340

Therefore, minimum cost for unit car is

$C(x) = 0.8x^2 -544x +97410$

$= 0.8(340)^2 -544(340) +97410$

= 4930

Use technology or a z-score table to answer the question. The weights of boxes of rice produced at a factory are normally distri

lesantik [10]

935 of the boxes will weigh 25 oz or less.

The z-score for this value is
$z=\frac{25-24}{1.3}=\frac{1}{1.3} = 0.77$

Looking this up in a z-table (http://www.z-table.com) we see that the probability of something being less than or equal to this value (the area under the curve to the left) is 0.7794.

Multiply this probability by the number of items:
0.7794(1200) = 935.28 ≈ 935.
