what value of c makes the equation true?

3/6=4/c

It looks like you want to find the height of the green region. If so then that would be about 5.2 mL since the top part of the green area is around the first smaller tick above the 5.

Each smaller tickmark is 1/5 = 0.2 of a full unit. Note how there are 5 smaller tickmark spaces to make up a full unit (when we go from 5 to 6, there are 5 smaller tickmark spaces we have to move)

Answer:

x =2

Step-by-step explanation:

The x- intercept is when y = 0

Hence, 5x - 2y = 10

5x - 2(0) = 10

5x = 10

Therefore, x = 2

Answer:

The dimensions of the piece of metal can be represented by x and x+10.

Now, 2 in squares are being cut out of each corner.

So the new dimensions are x-4 (2in from each side) and x+10-4 or x+6.

When you fold it up, the height becomes 2 and the base has dimensions x-4 and x+6. Now plug this into the volume formula.

V=l*w*h

1302 = (x+6)(x-4)(2)

651   = x2+2x-24

0      = x2 + 2x-675

0      = (x+27)(x-25)

x=-27 reject since lengths cannot be negative or x=25.

So your original dimension for the piece of metal are 25 by 35.

Answer:

B) approximately normal with mean 2.3 and standard deviation 2

Step-by-step explanation:

Given the following :

Mean crimes per day = 2.3

Standard deviation = 2

Number of samples = 100

Sampling distribution of the mean:

According to the central limit theorem:

Sample mean = population mean

2.3 = 2.3

The standard deviation of the sample (s) : ratio of the population standard deviation and square root of the sample size.

s = population standard deviation / √sample size

s = 2 / √100

s = 2 / 10

s = 0.2

The central limit theorem also posits that once ths sample size is large enough, the sampling of the sample mean will be approximately normal.

Hence, the distribution is approximately normal, with mean of 2.3 and standard deviation of 0.2

Answer: B

Answer:

Solution : Option B

Step-by-step explanation:

Taking a look at the graph, we can see that the parabola has the following features.

Vertex : (3, - 4)

y - intercept : (0, 5)

x - intercept : (1, 0) and (5, 0)

axis of symmetry : x = 3

The vertex, y - intercept, and x - intercept can all be determined through the intersection of the graph at a certain point. However the axis of symmetry is the line with which splits this parabola into two " similar " parts.

Your solution is option b.

S = Total students

B = number that had bikes

M = number that had a master card

P = number that had a phone

S = 200

B = 110

M = 25

P = 130

BM = 50

MP = 30

BP = 60

BMP = 10

B + M + P = 110 + 25 + 130 = 265

BM + MP + BP - BMP = 50 + 30 + 60 -10 = 130

265 - 130 = 135

Students that had none of the three = 200 - 135 = 65

Answer:

E(Y) = √a + √(a+12)

Step-by-step explanation:

X1 and X2 are independent variables while Y is the dependent variable, such that

Y = f(X1, X2)

Meaning Y is a function of X1 and X2

In this case,

Y = 2√X1X2

When (X1, X2) = (a, 1) ; Y = 2√a

When (X1, X2) = (a+12, 1) ; Y = 2√a+12

The expected value of Y is

[2√a + 2√a+12] ÷ 2  = √a + √a+12

=480/10

=48

Answer:

48.

Step-by-step explanation:

There are a total of 10 lecturers in the list

You find the mean by dividing the sum of all the ages by 10.

The mean age = 480/10 = 48.

Answer:

Largest p value

Step-by-step explanation:

The p value is basically used to check if an effect is in existence. A high p value shows that the evidence is weak and cannot be used to say an effect exists.

A p value that is greater than 0.05 is considered to be large and it shows weak evidence against H0, the null hypothesis.

Therefore of the 10 variables, we can use the criterion of largest p values to eliminate one of the variables.

Answer: 354500m²

Step-by-step explanation:

Area of the recreation park  = 560m x 700m

                                               = 392000m²

Area used for soccer and baseball = 250m x 150m

                                                          = ¹⁵⁰⁰⁰⁰/₄

                                                          = 37500m².

Area of the remaining park  = 392000 - 37500

                                              = 354500m²

Answer: y=34

Step-by-step explanation:

input  -2 into the equation and solve for  y.

y= 8 - 5(-2) + 4(-2)^2

y = 8 + 10 + 4 * 4

y = 8 + 10 + 16

y= 18 + 16

y = 34

Answer:

34

Step-by-step explanation:

We simply plug in x = -2 into the equation so when x = -2:

y = 8 - 5 * (-2) + 4 * (-2)² = 8 + 10 + 16 = 34.

[tex]\mathbf { \int _ c Fdr= - \dfrac{9 \pi ^2}{8} - \dfrac{3}{2} }[/tex]

Step-by-step explanation:

GIven that:

[tex]r(t) = (sin \ t, cos \ t, t)[/tex]

[tex]r' (t) = (cos \ t, -sin \ \ t, 1)[/tex]

[tex]F(x, y, z) = ( -x, -2y , - z)[/tex]

[tex]F(r(t)) = ( sin \ t , - 2 cos \ t, - 1 t)[/tex]

[tex]F(r(t)) \times r'(t) = (sin \ t, - 2 \ cos \ t , -1 \ t)( cos \ t , - sin \ t , 1 )[/tex]

[tex]= sin t \ cos t + 2 \ sin t \ cos t - 1t[/tex]

[tex]= 3sint \ cost - 1 t[/tex]

[tex]\int _ c Fdr = \int ^b_a f(r(t)) \times r'(t) \ dt[/tex]

[tex]= \int^{3 \pi/2}_0 \ [3 sin \ t \ cos \ t - 1 \ t ] \ dt[/tex]

[tex]= 3 \int ^{3 \pi/2} _0 \ cos \ t ( sin \ t \ dt ) - 1 \int ^{3 \pi/2}_0 \ (t) \ dt[/tex]

Let   cos t = u   &

sint  dt = du

[tex]= 3 \int ^{3 \pi/2_} } _0 \ udu - 1 \int ^{3 \pi/2}_0 \ (t) \ dt[/tex]

[tex]= 3 [ \dfrac{u^2}{2}]^{3 \pi/2}_0 - 1 [ \dfrac{t^2}{2}]^{3 \pi/2}_0[/tex]

[tex]= \dfrac{3}{2} [ cos ^2 \ t ] ^{3 \pi/2} _0- \dfrac{1}{2} ( \dfrac{ 3 \pi }{2 })^2 - 0^2[/tex]

[tex]= \dfrac{3}{2} [ cos ^2 \ \dfrac{3 \pi}{2} - cos ^2 \ 0 ] - \dfrac{1}{2}( \dfrac{9 \pi^2}{4})[/tex]

[tex]= \dfrac{3}{2} ( 0 -1 ) - \dfrac{9 \pi^2}{8}[/tex]

[tex]= - \dfrac{3}{2} - \dfrac{9 \pi ^2}{8}[/tex]

[tex]\mathbf { \int _ c Fdr= - \dfrac{9 \pi ^2}{8} - \dfrac{3}{2} }[/tex]

To answer this question, we apply:

∫CF×dr = ∫ c F (r(t)) × dr

Solution is:

( 1/2)  - (9/8)×π

We know  r(t) =  sint i + cost j + t k

Then  dr = ( cost i - sint j + k ) dt

And  F ( x , y , z ) = -x i - 2y j - z k

Then  F ( r(t)) =  - sint i - 2 × cost j - t × k

And F ( r(t)) × dr  = (- sint×cost + 2 ×sint ×cost - t ) dt

∫F (r(t)) × dr = ∫ (- sint×cost + 2 ×sint ×cost - t ) dt  

Integration limits 0≤  t  ≤ ( 3/2 ) π

∫ (- sint×cost + 2 ×sint ×cost - t ) dt  = ∫ ( sint ×cost - t ) dt

∫ sint ×cost × dt  - ∫ t ×  dt

∫F (r(t)) × dr = (1/2) sin²t  - ( 1/2) × t² | 0  y  (3/2) π

∫F (r(t)) × dr = (1/2)× ( -1)² - 0 - ( 9/8 ) × π - 0

∫F (r(t)) × dr = ( 1/2)  - (9/8)×π

Answer:

We can conclude that there is sufficient evidence to state that the companies claim is not false      

Step-by-step explanation:

From the question we are told that

    The  population proportion is  [tex]p = 0.35[/tex]

   The  level of significance is  [tex]\alpha = 0.10[/tex]

    The sample  size is  n  =  50

Generally the  sample proportion is mathematically represented as

     [tex]\r p = \frac{16}{50 }[/tex]

    [tex]\r p = 0.32[/tex]

The null hypothesis is  [tex]H_o : p\ge 0.35[/tex]

The  alternative  hypothesis is  [tex]H_a : p< 0.35[/tex]

Generally the standard error is evaluated as

      [tex]SE = \sqrt{ \frac{0.35 (1- 0.35 )}{ \sqrt{50 } } }[/tex]

      [tex]SE = 0.067[/tex]

So  

    The test statistics is  evaluated as

                [tex]t = \frac{\r p - p }{ SE }[/tex]

=>             [tex]t = \frac{0.32 - 0.35 }{ 0.067 }[/tex]

=>             [tex]t = -0.45[/tex]

The  p-value is obtained from the z-table  , the values is  

       [tex]P( Z < -0.45) = 0.32636[/tex]

From the calculation we see that

        [tex]p-value > \alpha[/tex] so we fail to reject the null hypothesis

Hence we can conclude that there is sufficient evidence to state that the companies claim is not false

Hello,

4. you have sequences defined by the first term and a recursive relation.

[tex]a_1=3\\\\a_n=2a_{n-1} \ \ \text{ for n}> 1[/tex]

Take n = 2, it gives

[tex]a_2=2a_1[/tex] , right?

But you know [tex]a_1=3[/tex]

so [tex]a_2=2a_1=2*3=6[/tex]

This is the second term. You are asked to find the first three terms.

Now, let's take n = 3

[tex]a_3=2a_2=2*6=12[/tex]

So the first three terms are 3, 6, 12.

6.

[tex]a_1=12\\\\a_2=\dfrac{1}{2}a_1+1=\dfrac{12}{2}+1=6+1=7 \\ \\a_3=\dfrac{1}{2}a_2+1=\dfrac{7}{2}+1=\dfrac{9}{2}[/tex]

Answer:

126 meters

Step-by-step explanation:

First, let's find the circumference of the pond. We know that C = πd, π = 3.14 and d = 10 so the circumference is 3.14 * 10 = 31.4 meters. However, the person walks around the pond 4 times so the answer is 31.4 * 4 = 125.6 meters which rounds to about 126 meters.

Answer:

  A.  $2.26

Step-by-step explanation:

An equation for Harper's balance can be written similar to the one written for Raymond's balance. It will be ...

  H(t) = 110(1.035)^t

For t = 2, the two balances will be ...

  H(2) = 110(1.035^2) = 117.83

  R(2) = 110(1.025^2) = 115.57

The difference is ...

  $117.83 -115.57 = $2.26

Harper's account will have $2.26 more.

_____

As a quick estimate or sanity check, you can see that Harper's interest rate is 1% more than Raymond's. So, in 2 years, he will earn a little more than 2% more on his investment than Raymond earns. 2% of $110 is $2.20, so the difference can be expected to be slightly more than this.

Answer:

86.64%

Step-by-step explanation:

We solve for the above question using z score formula

z score formula = z = (x - μ)/σ

where

x is the raw score

μ is the population mean

σ is the population standard deviation.

For x = 350, μ = 500, σ = 100

z score = 350 - 500/100

= -150/100

= -1.5

Using the z score for normal distribution

Probability (z = -1.5) = P(x = 350).

= 0.066807

For x = 650, μ = 500, σ = 100

z score = 650 - 500/100

= 150/100

= 1.5

Using the z score for normal distribution

Probability (z = 1.5) = P(x = 650).

= 0.93319

The probability of people who write this exam and obtain scores between 350 and 650

P < 350 < x < 650 = P(x ≤ 650) - P(x ≤ 350)

= P(z = 1.5) - P(z = -1.5)

= 0.93319 - 0.066807

= 0.866383

Therefore, the percent of people who write this exam and obtain scores between 350 and 650 is

0.866383 × 100

= 86.6383%

Approximately ≈ 86.64%

Hello, let's note

[tex]f(x)=x^4-3x^3+x^2+3x-2\\\\f(1)=1-3+1+3-2=0[/tex]

So we can put (x-1) in factor. We are looking for a and b such that

[tex]f(x)=(x-1)(x^3+ax^2+bx+2)=x^4+(a-1)x^3+(b-a)x^2+(2-b)x-2[/tex]

We identify the like terms, it comes

a-1=-3 <=> a = -2

b-a=1 <=> b = 1 + a = -1

2-b=3

So it comes.

[tex]f(x)=(x-1)(x^3-2x^2-x+2)[/tex]

And we can go further using the same method to find that

[tex]x^3-2x^2-x+2=(x-1)(x^2-x-2)[/tex]

The sum of the zeroes is 1=2-1 and the product is -2=(-1)*2, so, we can factorise.

[tex]\boxed{f(x)=(x-1)^2(x+1)(x-2)}[/tex]

The sign of f(x) is the same as the sign of (x+1)(x-2) as a square is always positive.

To find the sign of a product, we can apply the following.

"- multiplied by - gives +"

"+ multiplied by + gives +"

"- multiplied by + gives -"

"+ multiplied by - gives -"

This is this what we are doing below.

[tex]\begin{array}{|c|ccccccc}x&-\infty&&-1&&2&&+\infty\\---&---&---&---&---&---&---&---\\x+1&-&-&0&+&3&+&+\\---&---&---&---&---&---&---&---\\x-2&-&-&-3&-&0&+&+\\---&---&---&---&---&---&---&---\\f(x)&+&+&0&-&0&+&+\\\end{array}[/tex]

So, to answer the question

[tex]\Large \boxed{\sf \bf \ f(x) < 0 <=> -1 < x < 2 \ }[/tex]

Answer:

see below (I hope this makes sense and I hope it helps!)

Step-by-step explanation:

Points are found in the form (x, y) where x represents the x - value which is basically how far you move from the origin on the x-axis, and the same goes for y except it represents how far you move from the origin on the y-axis. A positive x means you move right, a negative x means you move left, a positive y means you move up and a negative y means you move down. Following these rules, to plot (2, 3), you move 2 units right and 3 units up from the origin and to plot (3, 2), you move 3 units right and 2 units up from the origin. The difference between plotting the two points is that first of all, they are different points so they are in different locations and second, their coordinates are "flipped"; what I mean by that is the x-coordinate of the first point is the y-coordinate of the second point and vice versa. Therefore, you move the same amount but in different directions.

These points are similar.

They both lie in quadrant 1.

However, the x coordinate is different in each ordered pair.

So (3, 2) moves farther from the origin than (2 , 3).

However, (2, 3) moved farther up than (3, 2).

Take a look below.
