Which expression is equivalent to 3/5 divided by 7/9

The perimeter of a shape is the total measurement of all the edges of a shape.

Perimeter of the square is 460 unit.

Since, coordinates of three vertices of square ABCD are given as   A(−212,112),   B(−212,−3) and C(2,112).

If coordinate of M(a, b) and N(c, d) are given.

Then by using distance formula,

[tex]MN=\sqrt{(d-b)^{2} +(c-a)^{2} }[/tex]

Similarly,  [tex]AB=\sqrt{(-3-112)^{2}+(-212+212)^{2} } \\\\AB=115[/tex]

In square, all four sides are equal.

Perimeter of Square, [tex]=4*side[/tex]

                                  [tex]=4*115=460[/tex] unit.

there are 195 girls

Step-by-step explanation:

the equation is: 364= 2x+26

subtract 26 from both sides and you get 338

338 divided by 2 is 169, therefore there are 169 boys.

169+26 more girls is 195

Answer: Choice C

9(51-12) = 9(51) - 9(12)

============================================

Explanation:

The distributive property is

a(b+c) = a*b + a*c

which can also be written as

a(b-c) = a*b + a*(-c) = a*b - a*c

In this case we're using

a(b-c) = a*b - a*c

where a = 9, b = 51, c = 12

Step-by-step explanation:

The alpha level set at the beginning of of an experiment is used by the researcher to the limit the probability if making a type 1 error. The type 1 error is committed when a true null hypothesis is incorrectly rejected.

The type 2 error on the other hand is committed when fail to reject a false null hypothesis.

Hence, in other to forestall the risk of incorrectly rejecting a true null hypothesis, the alpha level is set.

When critical region is split across both tails of the distribution, The z-score boundaries at an alpha level α = .05

α = .05 (95% confidence level)

When region is split into 2:

α/2 = .05/2

α/2 = 0.025

Loooking up the z table for the Zscore with probability of 0.025

Zscore = ±1.96

The alpha level, which would be chosen at the start of an investigation, is utilized by the investigator to restrict the likelihood of making a type 1 error and the z-score will be "[tex]\pm[/tex] 1.96".

According to the question,

Whenever the genuine null hypothesis has been wrongly dismissed or discarded, a type 1 problem happens.

When the crucial zone is divided between the distribution's two tails. At an alpha level, the z-score boundaries be:

95% confidence level, α = 0.05

Now,

→ [tex]\frac{\alpha}{2} = \frac{0.05}{2}[/tex]

By applying cross-multiplication, we get

  [tex]\frac{\alpha}{2} = 0.025[/tex]

hence,

By using the z table,

Z-score = [tex]\pm[/tex] 1.96    

Thus the above answer is correct.

I think is the same question for this answer

Answer:

Considering the first statement

Standard deviation is resistive to unusual values    

 This statement is false because standard deviation is the numeric measure of deviation of the each observation from the mean

Considering the second  statement    

The standard deviation of a set of values is equal to 0 if and only if all of the values are the same.

This statement is true because standard deviation is the numeric measure of deviation of the each observation from the mean.

Considering the third  statement

Standard deviation is never negative.

This statement is true because standard deviation is the numeric measure of deviation of the each observation from the mean.

Considering the fourth statement

Changing the units of a set of values (e.g., converting from inches to feet) does not affect its standard deviation

 This statement is false because standard deviation is the numeric measure of deviation of the each observation from the mean

Considering the fifth  statement

If a set of values has a mean of 0 and a standard deviation that is not 0, then adding a new data point with a value of 0 will have no effect on the standard deviation.

This statement is false because , let take an example

    x     -4 - 3 0 3 4

Generally the mean is mathematically evaluated as

    [tex]\= x =  \frac{\sum x_i }{n}[/tex]

=>   [tex]\= x =  \frac{-4+ (- 3)+ 0 + 3 + 4 }{5}[/tex]

=>   [tex]\= x =  0 [/tex]

Generally the standard deviation is mathematically evaluated as      

     [tex]\sigma  =  \sqrt{\frac{\sum (x_ i - \= x )^2}{y} }[/tex]

      [tex]\sigma  =  \sqrt{\frac{ (-4  - 0 )^2 + (- 3 - 0 )^2 + (0 - 0 )^2 + (3 - 0)^2 + (4 - 0 )^2}{5} }[/tex]

=>        [tex]\sigma  = 3.16 [/tex]

Now when zero is removed the standard deviation is  

[tex]\sigma_1  =  \sqrt{\frac{ (-4  - 0 )^2 + (- 3 - 0 )^2 + (3 - 0)^2 + (4 - 0 )^2}{4} }[/tex]

=>   [tex]\sigma_1  =  3.54 [/tex]

Since  [tex]\sigma  \ne  \sigma _1[/tex] the above statement is  false

Considering the sixth  statement

Standard deviation represents how far a group of values are from the mean of those values, on average.

This statement is true because standard deviation is the numeric measure of deviation of the each observation from the mean.

Answer:

Explained below.

Step-by-step explanation:

In this case we need to determine if there has been an increase in the proportion of rooms occupied over the one-year period.

(a)

The hypothesis can be defined as follows:  

H₀: The proportion of rooms occupied over the one-year period has not increased, i.e. p₁ - p₂ ≤ 0.  

Hₐ: The proportion of rooms occupied over the one-year period has increased, i.e. p₁ - p₂ > 0.  

(b)

The information provided is:

n₁ = 1750

n₂ = 1800

X₁ = 1470

X₂ = 1458

Compute the sample proportions and total proportions as follows:

 [tex]\hat p_{1}=\frac{X_{1}}{n_{1}}=\frac{1470}{1750}=0.84\\\\\hat p_{2}=\frac{X_{2}}{n_{2}}=\frac{1458}{1800}=0.81\\\\\hat p=\frac{X_{1}+X_{2}}{n_{1}+n_{2}}=\frac{1470+1458}{1750+1800}=0.825[/tex]

(c)

Compute the test statistic value as follows:

[tex]Z=\frac{\hat p_{1}-\hat p_{2}}{\sqrt{\hat p(1-\hat p)\times [\frac{1}{n_{1}}+\frac{1}{n_{2}}]}}[/tex]

   [tex]=\frac{0.84-0.81}{\sqrt{0.825(1-0.825)\times [\frac{1}{1750}+\frac{1}{1800}]}}\\\\=2.352[/tex]

The test statistic value is 2.352.

(d)

The decision rule is:

The null hypothesis will be rejected if the p-value of the test is less than the significance level.

Compute the p-value as follows:

 [tex]p-value=P(Z>2.352)=1-P(Z<2.352)=1-0.99061=0.00939[/tex]

The p-value of the test is very small. The null hypothesis will be rejected at any significance level.

Thus, there enough evidence suggesting that there has been an increase in the proportion of rooms occupied over the one-year period.

Answer:

Answer:

when y=3,X=15

here X is five times the value of y

so now when y= 5 then the value of X will be 25

hope you understand......

When the value of y is 5 then the value of x will be 25.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that,

y ∝ x

If y = 3 then x = 15

As a result,

x = 5y

Put y = 5 in the above relation,

x = 5 × 5

x = 25

Thus, when the value of y is 5 then the value of x will be 25.

Answer:

it is just length plus width times two.

Step-by-step explanation:

Answer:

First, let's find the equations for our lines:

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

f(x) passes through (5,0) and (10, 10), then the slope is:

a = (10 - 0)/(10 - 5) = 10/5 = 2.

then we have:

y = 2*x + b

And when x = 5, we have y = 0.

0 = 2*5 + b

0 = 10 + b

b = -10

Then the equation for f(x) is:

y = f(x) = 2*x - 10.

Now for g(x) we have the points:

(3, 0) and (2, 10)

a = (10 - 0)/(2 - 3) = -10

y = -10*x + b

0 = -10*3 + b

b = 30.

y = g(x) = -10*x + 30.

A) Ok, the transformations:

Transformation 1 or T1.

f(x) = 2*x - 10

g(x) = -10*x + 30.

Then, we start with f(x):

First, we can move f(x) up 4 units and get:

f'(x) = 2*X - 6

Now we can dilate f(x) with a scale factor of -5 from the origin, now we get:

f''(x) = -5*f'(x) = -10*x + 30.

And this is g(x).

Transformation 2 or T2.

Move f(x) up 10 units, so now we have:

f'(x) = 2*x

Do a reflection over the x-axis, so the sign of y changes, and now we get:

f''(x) = -2*x

Do a dilation of scale factor 5

f'''(x) = 5*-2*x = -10*x

Now do a vertical translation of 30 units up.

f''''(x) = -10*x + 30 = g(x).

These are two transformations that start with f(x) and end with g(x).

B) Ok, as i was writting the transformations i already solved them, so this part is already done.

C) the equation for the transformations are:

T1) g(x) = -5*(f(x) + 4)

T2) g(x) =  -(f(x) + 10)*5 + 30

Zscore = (81.6 - 72.6) / 15

Zscore = 0.6

EMILIO:

Zscore = (225.3 - 205) / 29

Zscore = 0.7

ALISSA:

Zscore = (8.08 - 7.2) / 0.4

Zscore = 2.2
