Perform the following division. Round the answer to three decimal places. 126.4 ÷ 1.7 =

Answers

Answer 1

Answer: I am assuming that you are supposed to answer this division problem through the long division method. So my answer is going to be a step-by-step description of the long division solution for this problem.

The first step is to move the decimal point of the dividend and the divisor. Hence, 1264.0 and 17. The decimal point of the quotient shall then be written in alignment with the decimal point of the dividend.

Then we proceed with the division process, 126/17 gives us 7 (write this above the division bar). 7 multiplied by 17 gives 119 (write this under the divisor). So 126-119 is equal to 7. We then bring down the digit after 126 of the divisor, which is 4. So we now have 74. 74 divided by 17, we get 4. 4 multiplied by 17 gives 68. We subtract 68 from 74 and we have 6, bring down 0, we have 60. We then repeat the division-multiplication-subtraction process until we get to the third decimal place of the quotient.

Finally, the answer is 74.352.

Answer 2

Answer:

Answer: Our required value to three decimal places is 74.352.

Step-by-step explanation:

Since we have given that

126.4 ÷ 1.7

First we rewrite the above numbers :

$(1264)/(10)/ (17)/(10)$

Now, we will solve this:

$((1264)/(10))/((17)/(10))\n\n=(1264)/(17)\n\n=74.352$

Hence, our required value to three decimal places is 74.352.

The mean of a population being sampled is 64, and and the standard deviation is 6.If the sample size is 50, the standard error of the mean is . (Round off your answer to the nearest hundredth.)

Answers

Given:
mean of the population being sampled = 64
standard deviation = 6
sample size = 50

standard error of the mean=standard deviation of the original distribution
root of the sample size

standard error of the mean = 6 / √50
standard error of the mean = 6 / 7.07
standard error of the mean = 0.848 or 0.85

The mean of a population being sampled is 64, and and the standard deviation is 6.

If the sample size is 50, the standard error of the mean is 0.85. (Round off your answer to the nearest hundredth.)

The cost of stainless steel tubing varies jointly as the length and the diameter of the tubing. If a 5 foot length with diameter 2 inches costs $48.00 , how much will a 19 foot length with 3 inches diameter cost?

Answers

Answer:

$273.60

Step-by-step explanation:

The cost of stainless steel tubing varies jointly as the length and the diameter of the tubing.

i.e $C\propto L\cdot D$

i.e $C=k\cdot L\cdot D$

A 5 foot or 60 inches length with diameter 2 inches costs $48.00, so

$\Rightarrow 48=k* 60* 2$

$\Rightarrow k=(48)/(60* 2)=0.4$

Now the equation becomes,

$C=0.4\cdot L\cdot D$

So the cost of a 19 foot or 228 inches length with 3 inches diameter is,

$C=0.4* 228* 3=\$273.60$

Divide 85 into the ratio of 2:3:5

Answers

The actual amount that needs to be divided = 85
The ratio in which the amount needs to be divided = 2:3:5
Let us assume the common ratio to be = x
Then
2x + 3x + 5x = 85
10x = 85
x = 85/10
= 8.5
Then
The ratio in which the number 85 will be divided = 2 * 8.5:3 * 8.5:5 * 8.5
= 17:25.5:42.5
So from the above deduction we can see that the number 85 can be divided in the ratio 17:25.5:42.5
