Answer:

yes

Step-by-step explanation:

Answer:

(a) The sample size for this poll is, n = 762.

(b) The data is categorical.

(c) It would make more sense to use percentages as a summary of the data for this question.

(d) Approximately 511 individuals provided the response "Yes".

Step-by-step explanation:

(a)

It is provided that in a recent poll, 762 readers responded to the following question:

"If a constitutional amendment to ban a state income tax is placed on the ballot in Tennessee, would you want it to pass?"

The possible responses were Yes, No, or Not Sure.

So, the sample size for this poll is, n = 762.

(b)

The outcomes of the poll are:

1: Yes

2: No

3: Not Sure

The data is categorical.

Categorical data can take labels such as, Gender (M/F), indicators (0/1) and so on.

(c)

Averages can be computed only for quantitative variable.

So, it would make more sense to use percentages as a summary of the data for this question.

That is, the percentage of people saying Yes, No and Not sure.

(d)

The percentage of people saying Yes is, 67%.

Compute the number of people saying Yes as follows:

[tex]n(\text{Yes})=P(\text{Yes})\times n[/tex]

         [tex]=0.67\times 762\\=510.54\\\approx 511[/tex]

Thus, approximately 511 individuals provided the response "Yes".

Answer:

x = 18

Step-by-step explanation:

5(x - 8) = 50

Divide both sides by 5.

x - 8 = 10

Add 8 to both sides.

x = 18

Answer:

x=18

Step-by-step explanation:

5(x − 8) = 50.

5x-40=50

+40              +40

5x/5=90/5

x=18

Answer:

The correct answer is C

Step-by-step explanation:

X+U= [-1,  -1] on the top and [0, -23/4] on the bottom

Therefore A-(X+U) gives you [5/3, 7] on the top and [4, 5] on the bottom

Answer:

The answer is D.

Step-by-step explanation:

Given that the formula of surface area of rectangular prism is S.A = 2(length×width) + 2(length×height) + 2(width×height). Then substitute the values into the formula :

Let length = 5,

Let width = 3,

Let height = 2,

[tex]s.a = 2(5 \times 3) + 2(5 \times 2) + 2(3 \times 2)[/tex]

[tex]s.a = 2(15) + 2(10) + 2(6)[/tex]

[tex]s.a = 15 + 15 + 10 + 10 + 6 + 6[/tex]

Answer:

The answer is D

Step-by-step explanation:

If the pattern continues, so that each term is separated by a distance of 3, then the sequence is given by the recursive rule

[tex]\begin{cases}a_1=1\\a_n=a_{n-1}+3&\text{for }n>1\end{cases}[/tex]

From this definition, we can write [tex]a_n[/tex] in terms of [tex]a_1[/tex]:

[tex]a_2=a_1+3[/tex]

[tex]a_3=a_2+3=(a_1+3)+3=a_1+2\cdot3[/tex]

[tex]a_4=a_3+3=(a_1+2\cdot3)+3=a_1+3\cdot3[/tex]

[tex]a_5=a_4+3=(a_1+3\cdot3)+3=a_1+4\cdot3[/tex]

and so on, up to

[tex]a_n=a_1+(n-1)\cdot3[/tex]

(notice how the subscript on a and coefficient on 3 add up to n)

or

[tex]a_n=1+3(n-1)=3n-2[/tex]

Answer:

a. 135 is correct

Step-by-step explanation:

We have the following information:

dogs lover: 150

cats lover: 120

as the null hypothesis:

H, there are equal number of dogs lover and cats lover, so the expected frequency in each cell will be equal and that is:

f = (150 + 120) / 2

f = 270/2 = 135

Answer:

875 students are enrolled in this year's freshman class after the first week of classes.

Step-by-step explanation:

Last year, there were 950 students.

This year, the class is 10% smaller. So it's number of students is 100 - 10 = 90% of last year.

0.9*950 = 855

Initially, this year class had 855 students.

During the first week, 20 enrolled.

855 + 20 = 875.

So

875 students are enrolled in this year's freshman class after the first week of classes.

Answer:

x²+(y-5)²=25

Step-by-step explanation:

To convert polar into rectagular

[tex]->r=\sqrt{x^2+y^2} =>r^2=x^2+y^2\\[/tex]

also, y=rsin θ => sin θ=y/r

r= 10sinθ

r=[tex]\frac{10y}{r}[/tex] => r²=10y

therefore, x²+y²-10y=0

By completing the squares on y²-10y gives

x²+(y-5)²=25

which is the equation of the circle.

This is the Cartesian equation of a circle with center  ( 0, 5)    

and radius,  r=5

And in the other way if we convert L to mL we got:

[tex] 2L *\frac{1000mL}{1L} = 2000 mL[/tex]

And we see that [/tex] 200mL < 2000 mL[/tex]

So then the answer would be <

Step-by-step explanation:

For this case we can solve this problem converting ml to L or converting L to ml.

For the first case converting ml to L we got:

[tex] 200mL *\frac{1L}{1000 mL}= 0.2 L[/tex]

And we see that 0.2 L is lower than 2 L so then:

[tex] 200 mL < 2L[/tex]

And in the other way if we convert L to mL we got:

Answer: 15.85km

Step-by-step explanation:

The car starts at the point (0,0)

Let's define east as the positive x-axis and north as the positive y-axis.

first, the car travels 10km southeast, so the angle is -45° from the east.

Then the new position of the car is:

(10km*cos(-45°), 10km*sin(-45°)) = (7.07km, -7.07km)

Now, from this point the car travels 15km with an angle of 60° (counting from the east)

So the new position is:

(7.07km + 15km*cos(60°), -7.07km + 15km*sin(60°)) = (14.57km  , 5.91km)

The magnitude of a vector (x, y) is √(x^2 + y^2)

So the magnitude of the vector (14.57km  , 5.91km) is:

√((14.57km)^2 + (5.91km)^2) = 15.85km

The magnitude of the car's resultant vector is 15.72.

Given that,

A car travels 10km southeast,

And then 15 km in a direction 60 degrees north of east.

We have to find,

The magnitude of the car's resultant vector.

According to the question,

To resultant direction calculate by using the sum of vectors following all the steps given below.

A car travels 10 km southeast,

And then 15 km in a direction 60 degrees north of east.

The first vector has module is 10 and angle is 315°,

In the south direction, the angle is  270° and east is 360°,

So the angle in southeast,

[tex]\rm = \dfrac{270+360}{2}\\\\= \dfrac{630}{2}\\\\= 315 \ degree[/tex]

The second vector has module 15 and angle = 40°

Decompose both vectors in their horizontal and vertical component:

The horizontal component of the first vector is,

[tex]\rm = 10 \times cos(315) = 10 \times 0.70= 7.07[/tex]

The vertical component of the first vector is,

[tex]= \rm 10 \times sin(315) = -7.07[/tex]

The horizontal component of the second vector is,

[tex]\rm = 15 \times cos(60) = 15 \times 0.5= 7.5[/tex]

The vertical component of the second vector is,

[tex]\rm = 15 \times sin(40) = 15 \times 0.86= 12.99[/tex]

The sum of the horizontal component of the resultant vector is,

[tex]= 7.07+7.5=14.57[/tex]

And the sum of the vertical component of the resultant vector is,

[tex]= -7.07+12.99=5.91[/tex]

The magnitude of the vector (14.57km, 5.91km) is:

Therefore,

The magnitude of the car's resultant vector is,

[tex]\rm Resulatant = \sqrt{(14.57)^2+ (5.91)^2}\\\\ Resulatant = \sqrt{212.28+ 34.92} \\\ \\ Resulatant = \sqrt{247.20}\\\\ Resulatant = 15.72[/tex]

Hence, The required magnitude of the car's resultant vector is 15.72.

90 km/hr

Step-by-step explanation:

If x is the speed of the slower car, and x+20 is the speed of the faster car, then:

5x + 5(x+20) = 1000

x + x + 20 = 200

2x + 20 = 200

x + 10 = 100

x = 90

We can see that triangle JKM is a right triangle, with right angle at M. Segment KM is 6 units and segment MJ is 3 units. We can also see that KJ is hypotenuse of right triangle.

We will use Pythagoras theorem to solve for KJ as:

[tex]KJ^2=KM^2+MJ^2[/tex]

[tex]KJ^2=6^2+3^2[/tex]

[tex]KJ^2=36+9[/tex]

[tex]KJ^2=45[/tex]

Now we will take positive square root on both sides:

[tex]\sqrt{KJ^2}=\sqrt{45}[/tex]

[tex]KJ=\sqrt{9\cdot 5}[/tex]

[tex]KJ=3\sqrt{5}[/tex]

Answer:

total cost = $22.4 + $1.12 = $23.52

Step-by-step explanation:

Mr McNeil bought 2 magazines for $7.45 and 1 book for $14.95 . The sales tax is 6% . The total cost of Mr McNeil can be calculated as follows.

He bought 2 magazines for $7.45  .This means the sum of the prize of the 2 magazine he bought is $7.45 and the prize for the single book he bought is $14.95.  The total cost of the items he bought excluding the sales tax is the sum of the whole items he bought.

total cost excluding sales tax = $7.45 + 14.95 = $22.4

The sales tax is 5% which can be calculated as follows

5/100 × 22.4 = 112/100 = $1.12

The total cost of Mr McNeil purchase including his sales tax is

total cost = $22.4 + $1.12 = $23.52
