4 1/8 - 2 3/8 what is the answer to which question

Answer:

Socko gained 3/5 kg from month 1 to month 2.

Step-by-step explanation:

Socko mass was 3/10 kg in month 1 and 9/10 kg in month 2.

The amount of mass he gained is k.

3/10 + k = 9/10

Subtract 3/10 from both sides.

k = 6/10

Reduce the fraction.

k = 3/5

Answer: Socko gained 3/5 kg from month 1 to month 2.

Answer:

area = 4

Step-by-step explanation:

area = length × width

length= 3 1/3 =3/3 = 1 and width= 3

area = 1 × 3

Answer:

A) 1

f(g(1)) = 1

Step-by-step explanation:

Step(i):-

Given that the functions are f(x) and g(x)

f(x) = 3√x +1

and  y = g(x)

put x=1  ⇒ y = g(1) = 0   ( from  graph 1 is mapping '0')

Step(ii):-

f(g(1) = f(0)

        = 3√0 +1   (∵f(x) = 3√x +1)

       = 1

f(g(1)) =1

Answer:

2z + 5

Step-by-step explanation:

you have to combine like terms

subtract 4z - 2z and you get 2z

the number with the variable next to it goes first not the constant

2z + 5

the variable is z and the constant is 5 because it doesn't have variable next to it

hope this makes sense and helps :)

tell me if you have any questions

Step-by-step explanation:

Here as the like terms only are 4z and -2z so,

We simplify the like terms:

5 + 4z - 2z. [B.O.D.M.A.S rule] (subtraction only)

= 5 + 2z (Ans)

Answer:

Step-by-step explanation:

‘a’ in this question is the slope of the line. Slope is (y2-y1)/(x2-x1) for any two points. We can see the line intersects the point (0,0) and (-10/9) so the slope is -10/9 which is less than -1 so

Answer: the answer is D

Step-by-step explanation: jus got it right on usa test prep :))

The data set which could not be represented by the box plot is

{6, 4, 7, 9, 8, 8, 12, 10, 12, 13, 13}​

Option D is the correct answer.

It is the middle value of the given set of numbers after arranging the given set of numbers in order.

We have,

From the box plot,

Median = 9

Lower quartile = 7

Upper quartile = 12

Maximum = 14

Minimum = 4

Now,

Arrange the number in order.

A)

{12, 5, 10, 7, 8, 14, 7, 10, 4, 13, 9}

= {4, 5, 7, 7, 8, 9, 10, 10, 12, 13, 14}

Median = 9

Lower quartile = 7

Upper quartile = 12

Maximum = 14

Minimum = 4

B)

{8, 12, 7, 8, 4, 9, 10, 12, 6, 14, 13)

= {4, 6, 7, 8, 8, 9, 10, 12, 12, 13, 14}

Median = 9

Lower quartile = 7

Upper quartile = 12

Maximum = 14

Minimum = 4

C)

{14, 5, 13, 8, 8, 10, 9, 11, 12, 7, 4 }

= {4, 5, 7, 8, 8, 9, 10, 11, 12, 13, 14}

Median = 9

Lower quartile = 7

Upper quartile = 12

Maximum = 14

Minimum = 4

D)

{6, 4, 7, 9, 8, 8, 12, 10, 12, 13, 13}​

= {4, 6, 7, 8, 8, 9, 10, 12, 12, 13, 13}

Median = 9

Lower quartile = 7

Upper quartile = 12

Maximum = 13

Minimum = 4

Thus,

{6, 4, 7, 9, 8, 8, 12, 10, 12, 13, 13}​ is not represented by the box plot.

Answer:

2/8, 5/8

Step-by-step explanation:

[tex]\frac{1}{4}*\frac{2}{2} =\frac{2}{8} \\\\\frac{3}{8} +\frac{2}{8} =\frac{5}{8}[/tex]

Multiplying by 2/2 is like multiplying by 1, so it doesn't affect the value.

To add fractions with the same denominator just add the numerator, the denominator stays the same.

The fraction is 2/8 and the sum is 5/8.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

Given:

let the numerator be x when denominator is 8.

so, 1/4 = x /8

8 = 4x

x= 8/4

x= 2

Now, fraction resulted above is added with 3/8

2/8 + 3/8

= (2+3)/8

= 5/8

Hence, the sum is 5/8.

Answer:

0.0003 = 0.03% probability that the mean price per gallon is less than ​$2.812​

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Finite correction factor:

If the sample is more than 5% of the population, instead of Central Limit Theorem, we use the finite correction factor, as the standard deviation of the sampling distribution would be too big.

The mean price for regular gasoline at the pump was $2.816 per gallon and the standard deviation was ​$0.008 per gallon.

Large sample, so this can be treated as the population data. Then [tex]\mu = 2.816, \sigma = 0.008[/tex]

Sample of 45:

45/800 = 0.056 = 5.6% -> Sample more than 5% of the population, so we use the finite correction factor. This means that s will be multiplied by:

[tex]FCF = \sqrt{\frac{N-n}{N-1}}[/tex]

In which n is the size of the sample(45) and N is the size of the population (800). So

[tex]FCF = \sqrt{\frac{755}{799}} = 0.9721[/tex]

By the Central Limit Theorem, [tex]n = 45, s = 0.9721*\frac{0.008}{\sqrt{45}} = 0.00116[/tex]

What is the probability that the mean price per gallon is less than ​$2.812​?

This is the pvalue of Z when X = 2.812. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{2.812 - 2.816}{0.00116}[/tex]

[tex]Z = -3.45[/tex]

[tex]Z = -3.45[/tex] has a pvalue of 0.0003

0.0003 = 0.03% probability that the mean price per gallon is less than ​$2.812​

Third angle = 81°

Step-by-step explanation:

Given:

In triangle

Smallest angle = x

Second angle = x + 45

Third angle = 3x

Find:

All angle

Computation:

Using angle sum property

x + x + 45 + 3x = 180

5x + 45 = 180

x = 27

Smallest angle = 27°

Second angle = x + 45

Second angle = 27 + 45

Second angle = 72°

Third angle = 3x

Third angle = 3(27)

Third angle = 81°

Answer:

The value that corresponds to the 75th percentile is 16.35.

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

A normal distribution has a mean of 15 and a standard deviation of 2.

This means that [tex]\mu = 15, \sigma = 2[/tex]

Find the value that corresponds to the 75th percentile.

This is X when Z has a pvalue of 0.75. So X when [tex]Z = 0.675[/tex]

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.675 = \frac{X - 15}{2}[/tex]

[tex]X - 15 = 2*0.675[/tex]

[tex]X = 2*0.675 + 15[/tex]

[tex]X = 16.35[/tex]

The value that corresponds to the 75th percentile is 16.35.

Answer:

12.5 inches

Step-by-step explanation:

Given

[tex]Distance = 150\ miles[/tex]

[tex]Scale:= 24\ miles : 2\ inches[/tex]

Required

Determine the measurement in inches

Represent the inches equivalent with d.

So, the scale can also be calculated as:

[tex]Scale:= 150\ miles: d[/tex]

Equate both scales

[tex]150\ miles: d = 24\ miles ; 2\ inches[/tex]

Convert to fraction

[tex]\frac{d}{150\ miles} = \frac{2\ inches}{24\ miles}[/tex]

[tex]\frac{d}{150} = \frac{2\ inches}{24}[/tex]

Multiply both sides by 150

[tex]150 * \frac{d}{150} = \frac{2\ inches}{24} * 150[/tex]

[tex]d = \frac{2\ inches}{24} * 150[/tex]

[tex]d = \frac{2\ inches * 150}{24}[/tex]

[tex]d = \frac{300\ inches}{24}[/tex]

[tex]d =12.5\ inches[/tex]
