I need help please. I don’t know if I’m right.

Answer:

4775.22

Step-by-step explanation:

V= πr2h

Input your numbers into the equation, and it will give you this answer.

Answer:

91%

Step-by-step explanation:

The discount is $73 so we would get 73/80.

73/80 is also known as 73÷80

which would equal 0.9125

if we were to covert and round it to a percent, it would be 91%

(1)  Equivalent fractions (2) common denominator

Solution:

1. Equivalent fractions name the same amount.

Equivalent fractions are the same value with different numerator and denominator.

Example:

These values are same.

2. A common denominator is a common multiple of two or more denominators.

Example:

Here 6 is a common multiple of 2 and 3.

Hence the answer is (1)  Equivalent fractions (2) common denominator.

Answer:

V = 262’144 ft^3, surface area = 24’576 ft^2

Step-by-step explanation:

The volume con be find with this formula =

V = side^3

V = 64^3 = 262’144 ft^3

For find the surface area we can proceed in this way: first of all we can find the area of a face.

A = side^2 = 4096 ft^2

a cube has 6 faces, so we have to the mutiply the value six times.

Surface area = 4096  x 6 = 24’576 ft^2

Answer:

Only 60 is an identified outlier

Step-by-step explanation:

Given

Age group: 40 to 50

[tex]Min = 60[/tex]           [tex]Q_1 = 70[/tex]           [tex]Median= 73[/tex]

[tex]Q_3 = 76[/tex]              [tex]Max = 85[/tex]

Conditions for outlier

[tex]Value > Q_3 + 1.5 * IQR[/tex]

[tex]Value < Q_1 - 1.5 * IQR[/tex]

See attachment for complete question

Required

Which of 60, 62 and 84 is an outlier of age grout 40 to 50 years

First, calculate the IQR of group 40 to 50.

This is calculated as:

[tex]IQR = Q_3 - Q_1[/tex]

Where:

[tex]Q_3 = 76[/tex] and [tex]Q_1 = 70[/tex]

So:

[tex]IQR = 76 - 70[/tex]

[tex]IQR = 6[/tex]

Next, is to test the outlier conditions on each value (i.e. 60, 62 and 84)

Testing 60

Condition 1

[tex]Value > Q_3 + 1.5 * IQR[/tex]

[tex]60 > 76 + 1.5 * 6[/tex]

[tex]60 > 76 + 9[/tex]

[tex]60 > 85[/tex] --- False

Condition 2

[tex]Value < Q_1 - 1.5 * IQR[/tex]

[tex]60 < 70 - 1.5 * 6[/tex]

[tex]60 < 70 - 9[/tex]

[tex]60 < 61[/tex] --- True

Because one of the conditions is true, then 60 is an outlier of group 40 - 50 years

Testing 62

Condition 1

[tex]Value > Q_3 + 1.5 * IQR[/tex]

[tex]62> 76 + 1.5 * 6[/tex]

[tex]62 > 76 + 9[/tex]

[tex]62 > 85[/tex] --- False

Condition 2

[tex]Value < Q_1 - 1.5 * IQR[/tex]

[tex]62 < 70 - 1.5 * 6[/tex]

[tex]62 < 70 - 9[/tex]

[tex]62 < 61[/tex] --- False

Because both conditions are false, then 62 is  not an outlier of group 40 - 50 years

Testing 84

Condition 1

[tex]Value > Q_3 + 1.5 * IQR[/tex]

[tex]84> 76 + 1.5 * 6[/tex]

[tex]84 > 76 + 9[/tex]

[tex]84 > 85[/tex] --- False

Condition 2

[tex]Value < Q_1 - 1.5 * IQR[/tex]

[tex]84 < 70 - 1.5 * 6[/tex]

[tex]84 < 70 - 9[/tex]

[tex]84 < 61[/tex] --- False

Because both conditions are false, then 84 is  not an outlier of group 40 - 50 years

Answer:

whts the question??

Step-by-step explanation:

Answer:

Angle A = 68 degree

Angle B = 44 degree

Step-by-step explanation:

Sum of all interior angles = Angle A+Angle B+ Angle C

180 = 68+x+x-24

180 = 68+2x-24

180-68 = 2x-24

112+24 = 2x

136/2 = x

68 = x

Therfore, Angle A = 68 degree

Angle B = (x-24)

= (68-24)

= 44 degree

Answer:

0.153

Step-by-step explanation:

15% =0.15

0.153 = 0.153

1/12 =0.083

1/7=0.142

So the greatest one is 0.153

Complete question :

Two researchers, Jaime and Mariya, are each constructing confidence intervals for the proportion of a population who is left-handed. They find the point estimate is 0.13. Each independently constructed a confidence interval based on the point estimate, but Jaime’s interval has a lower bound of 0.097 and an upper bound of 0.163, while Mariya’s interval has a lower bound of 0.117 and an upper bound of 0.173. Which interval is wrong? Why?

Answer:

Mariya's interval

Step-by-step explanation:

Point estimate = 0.13

Mariya's confidence interval :

Lower boundary = 0.117

Upper boundary = 0.173

Jamie's confidence interval :

Lower boundary = 0.097

Upper boundary = 0.163

The correct confidence interval should have an average value equal to the value of the point estimate ;

Jamie's confidence interval average :

(0.097 + 0.163) / 2 = 0.26 / 2 = 0.13

Mariya's confidence interval average :

(0.117 + 0.173) / 2 = 0.29 / 2 = 0.145

Based on the confidence interval average obtained we can conclude that Mariya's interval is wrong as it the average obtained is greater than the point estimate.

0.145 > 0.13

Answer:

[tex](x,y) = (3,1)[/tex]

Step-by-step explanation:

Given

[tex]y < -x + 4[/tex]

[tex]y > 3x - 8[/tex]

Required

Solve graphically

See attachment for graph;

The blue shade represents [tex]y < -x + 4[/tex]

While the green, represents [tex]y > 3x - 8[/tex]

Next, determine the intersection points between the two lines

From the attached graph, we have:

[tex](x,y) = (3,1)[/tex]

Hence, the solution is: [tex](3,1)[/tex]

Answer:

45

Step-by-step explanation:

Answer:

X = 22

Step-by-step explanation:

This is a right triangle which means the angles add up to 90° total. So if 1 side is 15 and another side is 53 then 15 + 53 = 68 and 90 - 68 = 22 so X = 22 which is the missing side.

Answer:

x = -3

Step-by-step explanation:

1. Write the equation

3x + 7 = -2

2. -7 from both sides

3x = -9

3. Divide 3 from both sides to get x alone

x = -3

Answer:

Hello There!!

Step-by-step explanation:

3x+7=-2 (-7 from both sides)

-7 -7

3x=-9 (divide by 3 from both sides)

÷3 ÷3

x=-3

hope this helps,have a great day!!

Answer:

The thesis statement is unclear.

Step-by-step explanation:

When we observe the figure there are two semicircles , one of radius 14cm . And other will be of 14cm/2 = 7cm ( Since the 2nd semi circle is drawn taking radius of 1st semicircle as diameter.)

Now join T to the center of 2nd semi circle . Therefore , we have

[tex]\tt\to PR = 28cm \\\\\tt\to PQ + 14cm = 28cm \\\\\tt\to PM + MQ = 14cm \\\\\tt\to MQ = 14cm - 7cm \\\\\to\boxed{\orange{\tt MQ = 7cm }}[/tex]

Now , looking at the figure we know that radius is perpendicular to the tangent at point of contact . Here TR is tangent . Therefore ∆TRM is right angled triangle. Using Pythagoras Theorem we have,

[tex]\tt\to 21^2 = RT^2+7^2 \\\\\tt\to RT^2= 441 - 49 \\\\\tt\to RT =\sqrt{392}\\\\\tt\to\boxed{\orange{\tt RT = 19 .79 cm }}[/tex]

Answer:

$488778

Step-by-step explanation:

For a for interest is;

i = PRT/100

Where;

R is rate

P is Principal

T is time

i is interest

We are given;

R = 12.5% = 0.125.

T = 146 days = (146/364) = 0.4011

i = $245

Thus;

245 = (P × 0.125 × 0.4011)/100

Thus;

P = (245 × 100)/(O.125 × 0.401)

P = $488778

Answer:

Ok, what exactly is the question?

Step-by-step explanation:

Answer:5/6=25/blank

Step-by-step explanation:so 5/6 the top is times five forget the bottom for now just think of 5 and 25

[5x5] equals 25 so you already got the top

now for the bottom since you multiply the top by five you have to do that to the bottom so that will be    [6x5] that equals 30 so you got your answer

[25/30]

Step-by-step explanation:

Answer:

[tex]y = \frac{1}{2}x - 4[/tex]

Step-by-step explanation:

Given

[tex]y = \frac{1}{2}x[/tex]

Required

Shift [tex]3\ units[/tex] down and [tex]2\ units[/tex] right

[tex]y = \frac{1}{2}x[/tex]

Shift 3 units down

The rule is: (x,y)=> (x,y-a)

Where a is the number of units shifted down

In this case: [tex]a = 3[/tex]

So, we have:

[tex]y = \frac{1}{2}x[/tex] == > [tex]y = \frac{1}{2}x - 3[/tex]

Shift 2 units right

The rule is: (x,y)=>(x-b,y)

Where b is the number of units shifted right

In this case: [tex]b = 2[/tex]

So, we have:

[tex]y = \frac{1}{2}x - 3[/tex] ==> [tex]y = \frac{1}{2}(x - 2) - 3[/tex]

Open bracket:

[tex]y = \frac{1}{2}x - 1 - 3[/tex]

[tex]y = \frac{1}{2}x - 4[/tex]

Hence, the new equation after the transformation is:

[tex]y = \frac{1}{2}x - 4[/tex]
