Question 3: A small window in a barn is shaped like a parallelogram. The height of the window is half the length of the base of the window. The base of the window is 12 in. The length of the other side of the window is 10 in. What is the area of the window? A) 22 B) 60 C) 72 D) 120

The rounding off should be 1100.

Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.

Rounding numbers to the nearest hundred means we need to check the digit to the right of the hundreds place, that is, the tens place. For example, when 7456 is rounded to the nearest hundred, it becomes 7500.

Given numbers are 1143 and 1149.

According to the given numbers both the numbers rounded off nearest hundred.

The number 143 and 149 lies between 100 to 200.

So, the round off will be 100.

Answer:

-4.317

Step-by-step explanation:

The z test statistic for testing of 1-proportion can be computed as

[tex]z=\frac{phat-p}{\sqrt{\frac{pq}{n} } }[/tex]

We know that

phat=x/n.

We know that x=40 and n=120.

Thus,

phat=40/120=0.3333

p=hypothesized proportion=0.53

q=1-p=1-0.53=0.47

So, required z-statistic is

[tex]z=\frac{0.3333-0.53}{\sqrt{\frac{0.53(0.47)}{120} } }[/tex]

[tex]z=\frac{-0.1967}{ 0.04556 }[/tex]

z=-4.317.

Thus, the required test statistic value for given hypothesis is z=-4.317.

Answer:

3.12732 × 10⁹ beats

Step-by-step explanation:

Given that, in 1 min, the heart of an individual makes 70 beats, the number of beats the heart of the healthy individual makes in 85 years can be calculated as follows:

1 yr = 365 days, therefore,

85yrs = 85*365 = 31,025 days

1 day = 24 hours

31,025 days = 31,025*24 = 744,600 hours.

1 hr = 60 mins

744,600 hours = 744,600*60 = 44,676,000 mins

This means the individual lived for 44,676,000 mins (85yrs)

If 70 beats are made in 1 min, therefore, in 85yrs, the individual will make:

44,676,000*70 = 3,127,320,000 beats = 3.12732 × 10⁹ beats in 85yrs

Answer:

Step-by-step explanation:

[tex]logx -log(x-1)^2= 2 log(x-1)[/tex]

[tex]logx-2log(x-1) = 2log(x-1)[/tex]

[tex]logx=log(x-1)^4[/tex]

[tex]x=(x-1)^4[/tex]

[tex]x^4-4x^3+6x^2+1=0[/tex]

solve this equation

Answer: [tex]y=\frac{ln(x)}{ln(10)}[/tex]

Step-by-step explanation:

To find the inverse of the function, you first replace the y with x and x with y. Then you solve for y.

[tex]y=10^x[/tex]                                [replace y with x and x with y]

[tex]x=10^y[/tex]                                [find natural log of both sides to get y alone]

[tex]ln(x)=ln(10)^y[/tex]                    [divide ln(10) on both sides]

[tex]\frac{ln(x)}{ln(10)} =y[/tex]                              

Now that we have found y after switching y with x and x with y, we know that the inverse is [tex]y=\frac{ln(x)}{ln(10)}[/tex].

Answer:

Third graph

Step-by-step explanation:

First, find the solution to the equation of inequality given.

2k + 8 < 5k - 1

Subtract 5k from both sides

2k + 8 - 5k < 5k - 1 - 5k

-3k + 8 < -1

Subtract 8 from both sides

-3k + 8 - 8 < -1 - 8

-3k < -9

Divide both sides by -3. (Note: < will change to > when dividing both sides with negative number)

[tex] \frac{-3k}{-3} [/tex] > [tex] \frac{-9}{-3} [/tex]

k > 3

The graph that will represent this solution will show that all values of k are greater than 3. 3 is not included as a solution. The "o" on top of the 3 on the number line won't be shaded to indicate that 3 is not included. And also, the arrow will point from 3 towards our right.

Therefore, the 3rd graph is the answer.

Answer & Step-by-step explanation:

You can find a rational fraction equivalent to [tex]-\frac{1}{5}[/tex]  by multiplying the numerator and denominator by the same number. The number can be any:

[tex]-\frac{1}{5} *3\\\\-\frac{1}{5}*\frac{3}{3}=-\frac{3}{15}[/tex]

This works because if you simplify the new number, it will have the same value as the first fraction.

If you simplify both fractions to a decimal value, they both equal -0.2.

Answer:

56 + 6(n - 1)

Step-by-step explanation:

To know which of the equation represent the nth term, we simply test each equation to see the one that will satisfy the table given above.

This can be obtained as follow:

For 56 + 6(n - 1)

1. n = 2

56 + 6(n - 1) = 56 + 6(2 - 1)

= 56 + 6(1)

= 56 + 6

= 62

2. n = 5

56 + 6(n - 1) = 56 + 6(5 - 1)

= 56 + 6(4)

= 56 + 24

= 80

For 56 + 12(n - 1)

1. n = 2

56 + 12(n - 1) = 56 + 12(2 - 1)

= 56 + 12(1)

= 56 + 12

= 68

2. n = 5

56 + 12(n - 1) = 56 + 12(5 - 1)

= 56 + 12(4)

= 56 + 48

= 56 + 24

= 104

For 62 + 6(n - 1)

1. n = 2

62 + 6(n - 1) = 62 + 6(2 - 1)

= 62 + 6(1)

= 62 + 6

= 68

2. n = 5

62 + 6(n - 1) = 62 + 6(5 - 1)

= 62 + 6(4)

= 62 + 24

= 86

For 62 + 12(n - 1)

1. n = 2

62 + 12(n - 1) = 62 + 12(2 - 1)

= 62 + 12(1)

= 62 + 12

= 74

2. n = 5

62 + 12(n - 1) = 62 + 12(5 - 1)

= 62 + 12(4)

= 62 + 48

= 110

From the illustrations made above,

Only equation 56 + 6(n - 1) satisfied the table.

Therefore, the expression 56 + 6(n - 1) can be used to obtain the nth term.

Step-by-step explanation:

So we have the expression:

[tex]39\div(2+1)-2\times(4+1)[/tex]

Recall the order of operations or PEMDAS:

P: Parentheses

E: Exponents

M/D: Multiplication and Division (Whichever First)

A/S: Addition and Subtraction (Whichever First)

Thus, first do the operations inside the parentheses:

[tex]39\div(2+1)-2\times(4+1)\\=39\div(3)-2\times(5)[/tex]

Now, do division and multiplication:

[tex]39\div(3)-2\times(5)\\=13-2\times5[/tex]

And the multiplication:

[tex]13-2\times5\\=13-10[/tex]

And finally, subtract:

[tex]13-10\\=3[/tex]

Answer: Distance = 2.449

Step-by-step explanation:

Given that the distance that (5, 1) is from the origin. That is (0,0) to (5,1)

where

X1 = 0

X2 = 5

Y1 = 0

Y2 = 1

The distance from the origin to the point (5, 1) can be calculated by using the formulae

Substitute all the parameters into the formular

D = [tex]\sqrt{(X2-X1) + (Y2-Y1)}[/tex]

D = [tex]\sqrt{(5-0) + (1-0)}[/tex]

D = [tex]\sqrt{5 + 1}[/tex]

D = [tex]\sqrt{6}[/tex]

D = 2.44948

D = 2.449 ( Three decimal places)

By the divergence theorem, the flux of F across the boundary of a region, ∂R, is equal to the integral of div(F ) over the region itself, R. In this case, the flux would be

[tex]\displaystyle \iint_{\partial R}\mathbf F\cdot\,\mathrm d\mathbf S = \iiint_R\mathrm{div}(\mathbf F)\,\mathrm dx\,\mathrm dy\,\mathrm dz \\\\ = \int_0^1\int_0^3\int_0^1\frac{\partial(2x^2)}{\partial x} + \frac{\partial(5y^2)}{\partial y} + \frac{\partial(3z^2)}{\partial z} \,\mathrm dx\,\mathrm dy\,\mathrm dz \\\\ = \int_0^1\int_0^3\int_0^1 (4x+10y+6z)\,\mathrm dx\,\mathrm dy\,\mathrm dz = \boxed{60}[/tex]

In this exercise we have to calculate the flux by the divergent theorem:

[tex]\int\limits\int\limits_R\, ds = 60[/tex]

By the divergence theorem, the flux of F across the boundary of a region, ∂R, is equal to the integral of div(F ) over the region itself, R. In this case, the flux would be:

Answer:

Step-by-step explanation:

Since the above sequence is a geometric sequence

For an nth term in a geometric sequence

[tex]A(n) = a ({r})^{n - 1} [/tex]

where

a is the first term

r is the common ratio

n is the number of terms

From the question

a = - 6

To find the common ratio divide the next term by the previous term

That's

r = 18/-6 = - 3 or -54/18 = - 3

Since we are finding the 12th term

n = 12

Substitute these values into the above formula

We have

[tex]A(12) = - 6 ({ - 3})^{11} [/tex]

Number of ways top 3 cars finish the​ race = 39,270

Step-by-step explanation:

Given:

Total number of cars = 35

Number of top cars = 3

Find:

Number of ways top 3 cars finish the​ race

Computation:

It is a permutation based problem.

So,

npr = n! / (n-r)!

35p3 = 35! / (35! - 3!)

35p3 = 35 ! / 32!

35p3 = 35 × 34 × 33

35p3 = 39,270

Number of ways top 3 cars finish the​ race = 39,270
