Answer:

0/4, 0/6 those are examples of non benchmark fractions. 1/2 is a benchmark fraction.

Step-by-step explanation:

The required fraction that is said to be not a benchmark fraction is given as 1/8.5, 1/7, and similar fractions.

Fraction is defined as the number of compositions that constitutes the Whole.

here,
Benchmark fractions, this is the fraction values that are used frequently in any mathematical and analytical operations such values are, 1/2, 1/4, 3/4, and so on.
And none benchmark fraction values are 1/8.5, 1/7, and similar fractions. and their uses are none essential and none frequent.

Thus, the required fraction that is said to be not a benchmark fraction is given as 1/8.5, 1/7, and similar fractions.

Answer:

The building is 61.5 m tall

Step-by-step explanation:

The image below is a diagram where all the given distances and angles are shown. We have additionally added some variables:

h = height of the building

a, b = internal angles of each triangle

x  = base of each triangle

The angles a and b can be easily found by subtracting the given angles from 90° since they are complementary angles, thus:

a = 90° - 37° = 53°

b = 90° - 42° = 48°

Now we apply the tangent ratio on both triangles separately:

[tex]\displaystyle \tan a=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]

[tex]\displaystyle \tan 53^\circ=\frac{150-x}{h}[/tex]

[tex]\displaystyle \tan 48^\circ=\frac{x}{h}[/tex]

From the last equation:

[tex]x=h.\tan 48^\circ[/tex]

Substituting into the first equation:

[tex]\displaystyle \tan 53^\circ=\frac{150-h.\tan 48^\circ}{h}[/tex]

Operating on the right side:

[tex]\displaystyle \tan 53^\circ=\frac{150}{h}-\tan 48^\circ[/tex]

Rearranging:

[tex]\displaystyle \tan 53^\circ+\tan 48^\circ=\frac{150}{h}[/tex]

Solving for h:

[tex]\displaystyle h=\frac{150}{\tan 53^\circ+\tan 48^\circ}[/tex]

Calculating:

h = 61.5 m

The building is 61.5 m tall

Answer:

D. 2926.1 cm3

Step-by-step explanation:

To calculate volume of a cylinder, you need to use the equation V = pi r² h, where r is radius and h is height.

you have the right numbers to plug in, so pi times 8.4² times 13.2, which gives you 2926.05 which you round up to 2926.1 cm³

Answer:

d. The administrators are unable to tell if there is a true difference between Oklahoma and non-Oklahoma residents in their excitement to go home for the holidays because their interval covers 0.

Step-by-step explanation:

The confidence interval refers to a rabje of statistically calculated values used in establishing a certain level of confidence in the outcome of a data.

The confidence interval is calculated thus :

Mean ± (Zcritical * Error)

The ± sign ensures we have the lower and upper boundary of our confidence level.

From the confidence level given in the question : -1.78 to 3.27

Since 0 is contained in the confidence interval range given, then it can be concluded that the difference in excitement between Oklahoma and non oklahoma residents cannot be adequately established.

Answer:

The 90% confidence interval is  [tex] -0.3433<  \mu_1 - \mu_2 < 2.1433[/tex]

Step-by-step explanation:

From the question we are told that

   The sample mean for men is  [tex]\= x_1 = 64.5 \ years[/tex]

    The sample mean for women is  [tex]\= x_2 = 63.6 \ years[/tex]

     The sample size for men  is   [tex]n_1 = 35[/tex]

      The sample size for women is  [tex]n_2 = 39[/tex]

      The standard deviation for men is [tex]s_1 = 3.0[/tex]

       The standard deviation for women is  [tex]s_2 = 3.5[/tex]

From the question we are told the confidence level is  90% , hence the level of significance is    

      [tex]\alpha = (100 - 90 ) \%[/tex]

=>   [tex]\alpha = 0.10[/tex]

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

   [tex]Z_{\frac{\alpha }{2} } =  1.645 [/tex]

Generally the standard error is mathematically represented as

     [tex]SE = \sqrt{\frac{s_1^2 }{n_1} + \frac{s_2^2}{n_2} }[/tex]

=>  [tex]SE = \sqrt{\frac{3^2 }{35} + \frac{3.5^2}{39} }[/tex]

=>  [tex]SE = 0.7558[/tex]

Generally the margin of error is mathematically represented as

       [tex]E = Z_{\frac{\alpha }{2} } * SE[/tex]

=>     [tex]E = 1.645 * 0.7558[/tex]

=>     [tex]E = 1.2433[/tex]

Generally 90% confidence interval is mathematically represented as  

      [tex](\= x_1 - \= x_2) -E <  \mu_1 - \mu_2 <  (\= x_1 - \= x_2) -E [/tex]

=>    [tex](64.5 - 63.6) -1.2433<  \mu_1 - \mu_2 <(64.5 - 63.6) +1.2433[/tex]

=>    [tex] -0.3433<  \mu_1 - \mu_2 < 2.1433[/tex]

The solution is Option A.

The number of only children with no pets is given by the equation A = 63 and the percentage would be P = 37.5 %

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of only children with no pets be A

Now , the equation will be

The number of siblings with pets = 82

The number of siblings with no pets = 141

The number of only child with pets = 105

Now , let A = 63

So , the total number of children = 105 + 63 = 168

The percentage given is P = 37.5 %

So , the percentage of children with no pets P = ( number of only children with no pets / total number of children ) x 100

Substituting the values in the equation , we get

Percentage of children with no pets P = ( 63 / 168 ) x 100

Percentage of children with no pets P = 0.375 x 100

Percentage of children with no pets P = 37.5 %

Therefore , the value of A is 63

Hence , the number of children with no pets i 63

Answer:

the transformed function will be: [tex]\mathbf{g(x)=-\sqrt{\frac{1}{3} x}+2}[/tex]

Step-by-step explanation:

We need to transform [tex]f(x)=\sqrt{x}[/tex] into g(x) using following translations

1) reflection in the x-axis

The reflection across x-axis will be:

[tex]g(x)=-\sqrt{x}[/tex]

2) Horizontal shrink by a factor of 1/3

The horizontal shrink by a factor of 1/3 will make the function g(x)

[tex]g(x)=-\sqrt{\frac{1}{3} x}[/tex]

3) Vertical translation up 2 units

The vertical translation up 2 units will make the function g(x)

[tex]g(x)=-\sqrt{\frac{1}{3} x}+2[/tex]

So, the transformed function will be: [tex]\mathbf{g(x)=-\sqrt{\frac{1}{3} x}+2}[/tex]

A fraction which is less than 1/3 is 1/6

We can lessen a quantity if we take out some positive part from it.

Thus, suppose if it is given that there are 'T' things, then a quantity which is less than 'T' would be 'T - S'

where S is something positive.

(there can be infinite number of values less than a specific finite value, and similarly, there can be infinite number of values more than a specific finite value).

For the given case, the fraction given is 1/3

Let a fraction which is less than it be denoted by F

Then,

[tex]F < 1/3\\F = \dfrac{1}{3} - S[/tex]

Let S = 1/6

Then, we get value of F as:

[tex]F = \dfrac{1}{3}- \dfrac{1}{6} = \dfrac{2 - 1}{6} = \dfrac{1}{6}\\[/tex]

Thus, 1/6 is a fraction which is less than the given fraction 1/3

Answer:

$0.97

Step-by-step explanation:

Let the cost of a single apple is x and that of single mango is y.

ATQ,

3x+6y=9.15 ....(1)

8x+4y=11.92 ...(2)

Multiply equation (1) by 8 and equation (2) by 3

24x+48y=73.2 ...(3)

24x+12y=35.76  ...(4)

Subtract equation (2) from (1) :

24x+12y-(24x+48y) = 35.76  - 73.2

12y-48y = -37.44

-36y = -37.44

y = $1.04

Put the value of y in equation (1)

3x+6y=9.15

3x+6(1.04) = 9.15

3x = 9.15-6(1.04)

3x = 2.91

x = $0.97

Hence, the cost of single apple is $0.97.
