Step-by-step explanation:

What you want to do is solve for how much water will be for one fraction of juice concentrate.

To do that you can divide 750 by 250 to get 3. That means that 3 portions of water to one portion of concentrate would be the ratio.

Hope that helps and have a great day!

Answer: a. 2

Step-by-step explanation:

According to the Empirical rule, when data is normally distributed then 95% of the lies within 2 standard deviations from mean.

Given: The distribution of the heights of students in a large class is roughly bell-shaped ( i.e. Normally distributed).

The average height is 68 inches, and approximately 95% of the heights are between 62 and 74 inches.

Then, by  Empirical rule, 68 -2(standard deviations) =62  [lower limit]

⇒ 2(standard deviations)= 68-62 = 4

⇒ standard deviations=2

Hence, correct option is a. 2

Answer:

B-3

Step-by-step explanation:

According to the empirical rule, roughly 95% of the distribution is within 2 standard deviations of the mean.

The mean is 68. The distance from 62 to 68 is 6 inches

68-62=6

Cut that in half to get 6/2 = 3

So the standard deviation is 3

Answer:

The 98% confidence interval is [tex] 1713.23 <   \mu  <  1866.76 [/tex]

Step-by-step explanation:

From the question we are told that

   The population standard deviation is  [tex]\sigma = 158[/tex]

    The sample size is  n  =  23

    The sample mean is  [tex]\= x = 1790 \ dollars[/tex]

From the question we are told the confidence level is  98% , hence the level of significance is    

      [tex]\alpha = (100 - 98 ) \%[/tex]

=>   [tex]\alpha = 0.02[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  2.33[/tex]

Generally the margin of error is mathematically represented as  

      [tex]E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }[/tex]

      [tex]E = 2.33 *  \frac{158 }{\sqrt{23} }[/tex]

      [tex]E =76.76 [/tex]

Generally 98% confidence interval is mathematically represented as  

      [tex]\= x  -E <   \mu  <  \= x  +E[/tex]

       [tex]1790  -76.76 <  \mu  <  1790  +76.76  [/tex]

        [tex] 1713.23 <   \mu  <  1866.76 [/tex]

Answer:

one article costs 8.25$  15 articles cost 123.75

Step-by-step explanation:

set up a simple equation where a is one article

26a = 214.50

divide by 26 on both sides to isolate the variable

a=8.25

the cost of one article is 8.25

because you then want 15 articles, multiply 8.25 by 15 to get 123.75

The cost of 1 article is $8.25

The cost of 15 articles is $123.75

26 articles = 214.50

1 article= x

cross multiply

26x= 214.50

x= 214.50/26

x= 8.25

1 article= $8.25

15 articles= 15×8.25

= $123.75

Hence 1 article costs $8.25 and 15 articles cost $123.75

Answer:

125.15

Step-by-step explanation:

Just do it!

Answer:

352.5

or

705/2​

Step-by-step explanation:

4.23 ÷ 0.012 = 352.5

352.5 × 0.012 = 4.23

When 4.23 is divided by 0.012, we get 352.5.

Division in maths is the process of breaking a number up into equal parts, and finding out how many equal parts can be made. The division algorithm says when a number [a] is divided by [b], it will give quotient as [q] and remainder [r], then the following relation exist between a, b, q and r as -

a = bq + r

Given are two decimal numbers 4.23 and 0.012 such that → 4.23 divided by 0.012.

Assume that the number -

A = 4.23

B = 0.012

We have to find A/B, therefore, we can write -

A/B = 4.23/0.012A/B = 423000/1200 = 4230/12 = 352.5

Therefore, when 4.23 is divided by 0.012, we get 352.5 as the result.

Answer:

85.95

Step-by-step explanation:

If the local tax was 8% and we want to know what is was without the tax then we need to do 93.42 times .92

[tex]93.42*.92=85.9464[/tex]

Since money only goes to the hundredths place we need to round there

[tex]85.95[/tex]

Based on the amount that Adrian spent in total, the cost without taxes was $86.50.

The cost of the clothes was $93.42 including tax.

Assuming the original cost is x, the equation is:

Total cost = Original cost x ( 1 + tax)

Solving would give:

93.42 = x × (1 + 8%)

93.42 = 1.08x

x = 93.42 / 1.08

= $86.50

In conclusion, the cost without taxes was $86.50.

Given parameters:

              1 mile = 6 x 10⁴ inches

Average human hair  = 3 x 10⁻³ inches

Unknown:

How many times longer is a mile than a human hair;

Solution:

 Since we know that a mile 6 x 10⁴ inches , we can compare this quantity to the human hair;

     Number of times  = [tex]\frac{6 x 10^{4} }{3 x 10^{-3} }[/tex]

     Number of times  = 2 x 10⁴⁺³

     Number of times  = 2 x 10⁷

So, a mile is 2 x 10⁷ times longer than the human hair.
