Answer: 48.1%

Step-by-step explanation:

The percent markup is defined as:

PM = (gross benefit/cost per unit.)*100%

We know that the cost per unit is $35

then we have:

108% = (gross benefit/$35)*100%

gross benefit = (108%/100%)*$35 = $37.8

This means that a game is selled by $35 + $37.8 = $72.8

Now we have:

Markup percent = (gross benefit/selling price)*100% = ($35/$72.8)*100% = 48.1%

Step-by-step explanation:

side ratio =    big/small   = 28/4 = 7

perimeter ratio = side ratio = 7

-> perimeter ratio = big / small = big/34 = 7

-> big perimeter= 7*34 = 238

Answer

65 degrees

Step-by-step explanation:

The value of x for which Angle B is supplementary to Angle A would be x = 26.17.

Used the definition of supplementary angle that states,

The sum of supplementary angles in any figure gives 180 degrees always.

Given that,

Angle A measures (2x - 23)°.

And, Angle B is supplementary to Angle A and measures (4x + 46)°.

Since Angle A and B are supplementary.

Hence the sum of both Angles is 180 degrees.

This gives,

∠A + ∠B = 180°

Substitute the given values,

(2x - 23)° + (4x + 46)° = 180°

Combine like terms,

6x + 23 = 180

Subtract 23 on both sides,

6x = 180 - 23

6x = 157

Divide 6 on both sides,

x = 26.17

Therefore, the value of x = 26.17

Answer:

(x - 7)² + (y - 5)² = 116

Step-by-step explanation:

equation of a circle:

(x - h)² + (y - k)² = r²

where (h,k) is the centre and r is the radius

centre is the midpoint of the diameter:

(h,k) = (11+3)/2 , (-5+15)/2

(h,k) = (7,5)

diameter = sqrt[(15--5)² + (3-11)²]

diameter = sqrt(464) = 4sqrt(29)

radius = ½ diameter

radius = 2sqrt(29)

r² = 116

equation:

(x - 7)² + (y - 5)² = 116

Answer:

[x-7]^2 + [y-5]^2= 116

Step-by-step explanation:

General equation of a circle is

[x2 - xo]^2 + [y2- yo]^2 = r^2

Where xo and yo are coordinates of the circle at the origin.

But xo = [x2 + x1]/2

= 11 + 3 / 2 = 7

yo = [y2 + y1] / 2 = [-5 + 15] /2 = 5

x2= 11, x2= 3; y1= -5, y2= 15

[11-7]^2 + [15-5]^2 =

16+ 100=116 = r^2

From the expression below;

[x2-xo]^2 + [y2-yo] ^2 = r^2

[x1-xo]^2 + [y1-yo] ^2 = r^2

[x-7]^2 + [y-5]^2= 116

Answer:

the mean in set B is equal to the mean in set A (option C)

Question:

The question is incomplete as the answer choices were not given.Let's consider the following question:

Data set A is {30, 45, 32, 50, 33, 40, 44, 32}. Data set B is {28, 43, 30, 48, 35, 42, 46, 34}. which statement best compares the two data sets?

a) median for set A is equal to the median for set B

b) Range for set A is greater than range for set B 

c) The mean in set B is equal to the mean in set A

Step by step explanation:

We can describe a data set using four ways:

Center, spread, shape and unusual features.

Let's consider the center and spread.

Center: This is the median of the distribution.

Spread: This is the variation of the data set. If the range is wide, the spread is larger and If the range is small, the spread is smaller.

Rearranging the data set:

A = {30, 32, 32, 33, 40, 44, 45, 50}

B = {28, 30, 34, 35, 42, 43, 46, 48}

From the data:

The median for set A = (33+40)/2 = 73/2= 36.5

The median for set B = (35+42)/2 = 77/2= 38.5

Range = highest value - lowest value

The data ranges from 30 to 50 (range = 20) for A 

The data ranges from  28 to 48 (range = 20) for B

Mean for set A = (30+32+32+33+40+4445+50)/8 = 306/8 = 38.25

Mean for set B = (28+30+34+35+42+43+46+48)/8= 306/8 = 38.25

In both data set the mean is equal to 38.25.

Therefore the statement that best compares the two data sets is the mean in set B is equal to the mean in set A (C)

[tex]\frac{1}{2}[/tex] (one-half)

Step-by-step explanation:

Given: Fraction is [tex]\frac{15}{24}[/tex]

To find: the correct option

Solution:

A fraction represents part of a whole.

An improper fraction is a fraction in which numerator is greater than the denominator and a proper fraction is a fraction in which numerator is less than the denominator.

[tex]\frac{1}{2}=\frac{1\times 12}{2\times 12}=\frac{12}{24}< \frac{15}{24}\\\frac{7}{8}=\frac{7\times 3}{8\times 3}=\frac{21}{24}> \frac{15}{24}\\\frac{19}{24}> \frac{15}{24}\\\frac{6}{8}=\frac{6\times 3}{8\times 3}=\frac{18}{24}> \frac{15}{24}[/tex]

So, ratio [tex]\frac{1}{2}[/tex] is less than the given fraction [tex]\frac{1}{2}[/tex]

Answer:

rational

Step-by-step explanation:

The correct statement is:

c. The other zero can be either rational or irrational.

A quadratic equation with integer coefficients can have two distinct zeros, and if one of the zeros is irrational, the other zero can be either rational or irrational.

The nature of the zeros depends on the specific values of the coefficients in the quadratic equation.

A quadratic equation with integer coefficients can be written in the form: [tex]ax^2 + bx + c = 0[/tex], where a, b, and c are integers.

The solutions to this equation can be found using the quadratic formula:

[tex]\mathrm x = \frac{\mathrm{-b}\pm \sqrt{\mathrm b^2-4\mathrm a \mathrm c} }{2 \mathrm a}[/tex]

If one zero is irrational, it means that one of the solutions obtained from the quadratic formula is an irrational number.

However, the other solution can still be either rational or irrational.

The discriminant, [tex]b^2 - 4ac[/tex], determines the nature of the solutions.

If the discriminant is a perfect square, both solutions will be rational.

If the discriminant is not a perfect square, one solution will be irrational, and the other may be either rational or irrational.

Therefore, it is possible for the other zero to be rational or irrational, depending on the specific values of a, b, and c in the quadratic equation.

Thus, option (c) is the correct answer.

Answer:

Rohit is 6 years old

James is 15 years old

Step-by-step explanation:

the difference between their units is 3

Now we add the 9 years

the difference between their units should be 3 because they both age every year. the question was nice enough to give to same amount of units

Now we subtract James's original 'unit age' from his new one

We also need to make sure the difference between Rohit's original 'unit age' is 3

this 3 units represent the 9 years that have passed

To find James's age all we ahve to find is their original unit number

Answer:

94%

Step-by-step explanation:

We need to look at the graph. Olive wants the probability that 20 or more of the 50 babies were female. Looking at the graph, the x-axis is "number of females born out of 50 babies". We want to find the sum of all the ones that are at least 20, or 20 and above.

The numbers above the bars represents how many of each case there are. Above the bar labelled 20, there is the number 11, and so on. So, our sum is:

11 + 17 + 14 + 23 + 16 + 29 + 16 + 23 + 14 + 6 + 9 + 3 + 1 + 2 + 1 + 1 + 1 = 187

In total, there are 200 cases, so our probability is 187 / 200 = 93.5% ≈ 94%.

The answer is thus A.

Step-by-step explanation:

Step 1:  Count up how many babies are more than 20

[tex]11 + 17 + 14 + 23+16+29+16+23+14+6+9+3+1+2+1+1+1[/tex]

a) 0.9706 = 97.06% probability that x is less than 60.

b) 0.9987 = 99.87% probability that x is greater than 16.

c) 0.9693 = 96.93% probability that x is between 16 and 60.

a) 0.0668 = 6.68% probability that the thickness is less than 3.0 mm.

b) 0.0062 = 0.62% probability that the thickness is more than 7.0 mm

c) 0.9270 = 92.70% probability that the thickness is between 3.0 mm and 7.0 mm.

Step-by-step explanation:

Problems of normally distributed samples are 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.

1)

We have that [tex]\mu = 43, \sigma = 9[/tex]

a) x is less than 60

This is the pvalue of Z when X = 60.

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

[tex]Z = \frac{60 - 43}{9}[/tex]

[tex]Z = 1.89[/tex]

[tex]Z = 1.89[/tex] has a pvalue of 0.9706

0.9706 = 97.06% probability that x is less than 60.

b) x is greater than 16

This is 1 subtracted by the pvalue of Z when X = 16.

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

[tex]Z = \frac{16 - 43}{9}[/tex]

[tex]Z = -3[/tex]

[tex]Z = -3[/tex] has a pvalue of 0.0013.

1 - 0.0013 = 0.9987

0.9987 = 99.87% probability that x is greater than 16.

c) x is between 16 and 60

This is the pvalue of Z when X = 60 subtracted by the pvalue of Z when X = 16.

From a), Z when X = 60 has a pvalue of 0.9706.

From b), Z when X = 16 has a pvalue of 0.0013

0.9706 - 0.0013 = 0.9693

0.9693 = 96.93% probability that x is between 16 and 60.

d) x is more than 60

This is 1 subtracted by the pvalue of Z when X = 60.

From a), Z when X = 60 has a pvalue of 0.9706.

1 - 0.9706 = 0.0294

0.0294 = 2.94% probability that x is more than 60.

2)

Now [tex]\mu = 4.5, \sigma = 1[/tex]

a) the thickness is less than 3.0 mm

This is the pvalue of Z when X = 3.

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

[tex]Z = \frac{3 - 4.5}{1}[/tex]

[tex]Z = -1.5[/tex]

[tex]Z = -1.5[/tex] has a pvalue of 0.0668

0.0668 = 6.68% probability that the thickness is less than 3.0 mm.

b) the thickness is more than 7.0 mm

This is 1 subtracted by the pvalue of Z when X = 7.

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

[tex]Z = \frac{7 - 4.5}{1}[/tex]

[tex]Z = 2.5[/tex]

[tex]Z = 2.5[/tex] has a pvalue of 0.9938.

1 - 0.9938 = 0.0062

0.0062 = 0.62% probability that the thickness is more than 7.0 mm

c) the thickness is between 3.0 mm and 7.0 mm.

This is the pvalue of Z when X = 7 subtracted by the pvalue of Z when X = 3.

From b), Z when X = 7 has a pvalue of 0.9938.

From a), Z when X = 3 has a pvalue of 0.0668

0.9938 - 0.0668 = 0.9270

0.9270 = 92.70% probability that the thickness is between 3.0 mm and 7.0 mm.
