You would need 105 of sodium I found how much increase there was from 30 to 75 by doing 75/30 which is 2.5 that means the new amount of sodium would be 2.5 times 42 which is 105. You could also set up ratios and cross multiply like the picture I sent

Which of the below descriptions shows a possible HAMILTON PATH?

Vadim26 [7]

Option B: FECBAD is the Hamilton path

Explanation:

Given that ABCDEF is a graph with vertices A,B,C,D,E and F

We need to determine the Hamilton path.

Since, we know that a Hamilton path is a path that touches every vertex in a graph exactly once.

Option A: EFADECBA

The path touches the vertices E and A twice.

Hence, the path EFADECBA is not a Hamilton path.

Therefore, Option A is not the correct answer.

Option B: FECBAD

The path touches every vertex in the graph exactly once.

Hence, the path FECBAD is a Hamilton path.

Therefore, Option B is the correct answer.

Option C: ADEFBD

The path touches the vertex A twice because when the path travels from F to B the only way to travel through A.

Hence, the path ADEFBD is not a Hamilton path.

Therefore, Option C is not the correct answer.

Option D: ADECBAFE

The path touches the vertices E and A twice.

Hence, the path ADECBAFE is not a Hamilton path.

Therefore, Option D is not the correct answer.

In order to determine an interval for the mean of a population with unknown standard deviation, a sample of 24 items is selected

nikitadnepr [17]

If the sample size of population is 24 then the number of degrees of freedom for reading the t value is 23 which is option c.

Given sample size of 24,mean 23.

We have to determine the number of degrees of freedom which will be used to find the critical values of t.

Degree of freedom is the number of values in the final calculation of a statistic that are free to vary means that can change their values in the formula of calculating t.

t=(X-μ)/s/ $\sqrt{n}$

where X is sample mean ,

μ is hypothsised population mean

s is sample standard deviation

n is sample size.

Degree of freedom=n-1

In this question n is 24 so the degree of freedom =24-1=23.

Hence the number of degrees of freedom for reading the t value is 23.

If 47 Mph was a unit rate, how many hours would it take to travel 1 Mph?

insens350 [35]

Answer: um i think you asked the question wrong. But ok.

Step-by-step explanation:

= 47 miles per hour

This is a fraction equal to

47 miles ÷ 1 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 1

47 miles ÷ 1

1 hours ÷ 1

47 miles

1 hour

47 miles

hour

= 47 miles per hour
