Area of prallelogram

Answer:

{ 11, 19, 27, 35 }

Step-by-step explanation:

To find the range substitute each value of x from the domain into the relation

x = 3 : y → 4(3) - 1 = 12 - 1 = 11

x = 5 : y → 4(5) - 1 = 20 - 1 = 19

x = 7 : y → 4(7) - 1 = 28 - 1 = 27

x = 9 : y → 4(9) - 1 = 36 - 1 = 35

range is { 11, 19, 27, 35 }

Step-by-step explanation:

let the percent of found balloons be x

given,

total number of balloons= 70

number of found balloons= 28

according to the question,

x% of 70= 28

x/100 × 70 = 28

x=40

hence 40% of the balloons were found

Answer:

Option C

Step-by-step explanation:

Barrel (storage container) is enclosed in a small square fence.

Since, barrel is touching the surfaces from four sides of the cylindrical barrel.

Length of each side of the square fence = Diameter of the barrel

                                                                   = 2(radius of the barrel)

                                                                   = 2(1.5)

                                                                   = 3 feet

Perimeter of a square = 4(Side of a square)

                                     = 4(3)

                                     = 12 feet

Therefore, Option C will be the correct option.

60% higher than Travis

Answer:

Pedro: 1481 Base hits

Ricky: 1198 Base hits

Step-by-step explanation:

First, take the total amount of base hits last season 2679, then subtract how many more Pedro has 283.

2679 - 283 = 2396 now divide the sum in half  2396 ÷ 2 = 1198 that gives you how many each player has, you're then going to add the amount that you took off to only Pedras total since he had 283 more

Pedro: 1198 + 283 = 1481

Ricky: 1198

Answer:

Step-by-step explanation:

The standard form of the quadratic we need is

[tex]y=a(x-h)^2+k[/tex] where we have everything we need but a. That's what we will solve for.

x and y come from the coordinate given on the red graph:

x = 2 and y = 1

h and k come from the coordinates of the vertex:

(0, 0). Fill all that in and solve for a:

[tex]1=a(2-0)^2+0[/tex] and

1 = 4a so

a = 1/4 That makes our equation

[tex]y=\frac{1}{4}(x-0)^2+0[/tex] or simplified:

[tex]y=\frac{1}{4}x^2[/tex], choice B.

Step-by-step explanation:

RZT = 137

RZS = 56

SZT = 137 - 56 = 81

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

Work Shown:

Apply the cosine ratio to find the adjacent side AB

cos(angle) = adjacent/hypotenuse

cos(B) = AB/BC

cos(62) = AB/12

12*cos(62) = AB

AB = 12*cos(62)

AB = 5.6336587534307

AB = 5.6 cm

z-score representing 85% is 1.04 (from table)

Let x be the score representing the lower limit of 85%.

Use the formula to find z-scores:

We have:

Substitute the values and solve for x:

The lower limit of the top 15% is 85.28.

Since your score is greater than 85.28 you earned an A

Given:

The data values are:

21, 32, 17, 24, 15, 30, 28 and 26.

To find:

The first quartile, third quartile, and interquartile range.

Solution:

We have,

21, 32, 17, 24, 15, 30, 28, 26

Arrange the data values in ascending order.

15, 17, 21, 24, 26, 28, 30, 32

Divide the data set in two equal parts.

(15, 17, 21, 24), (26, 28, 30, 32)

Divide each parenthesis in two equal parts.

(15, 17), (21, 24), (26, 28), (30, 32)

Now, the first quartile is:

[tex]Q_1=\dfrac{17+21}{2}[/tex]

[tex]Q_1=\dfrac{38}{2}[/tex]

[tex]Q_1=19[/tex]

The third quartile is:

[tex]Q_3=\dfrac{28+30}{2}[/tex]

[tex]Q_3=\dfrac{58}{2}[/tex]

[tex]Q_3=29[/tex]

The interquartile range is:

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

[tex]IQR=29-19[/tex]

[tex]IQR=10[/tex]

Therefore, the first quartile is 19, third quartile is 29 and the interquartile range is 10.

Answer:

0.22222222222222

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Say the point below point B is point C.

AB belongs to triangle ABC.

To find hypotunuse AB, we need BC and AC so that we can use pythagorean thereom.

BC is already given --> 1.

AC is a diagonal of the rectangular prisms's base.

We already have 2 sides for the triangle that the base diagonal belong's to.

AC^2 = 4^2 + 6^2

AC^2 = 16 + 36 = 52

AC = √52

Now we have AC ad BC. We can find AB using pythagorean thereom.

AC^2 + BC^2 = AB^2

(√52)^2 + (1)^2 = AB^2

52 + 1 = AB^2

AB^2 = 53

AB = √53

option B

Answer: 4

Step-by-step explanation:

Using the 30°-60°-90° Triangle Theorem we know that the base side is half of the hypotenuse. That means it is half of 8 which is 4

Answer:

m<UVW = 156°

Step-by-step explanation:

Given:

m<PVW = 130°

m<UVP = 26°

Required:

m<UVW

Solution:

m<UVP + m<PVW = m<UVW (Angle Addition Postulate)

Substitute in the given values

26° + 130° = m<UVW

156° = m<UVW

m<UVW = 156°

Answer:

No, the absolute value of a number is different from the opposite.

Step-by-step explanation:

For example, the absolute value of 4 is 4.

l4l = 4

But the opposite of 4 is -4.

Absolute value is ALWAYS positive, but the opposite of a positive number is a negative number.

Answer:

A. 0.25 inches

B. 0.125 inches

Step-by-step explanation:

A.

The smallest increment is represented by 1/4. Converting this into decimal form would make this 0.25.

Work:

1/4 = x/100

1 × 100 = 4 × x

100 = 4x

25 = x

25/100

0.25

B.

The uncertainty is what is not labeled on the ruler. We know 0.25 (1/4), 0.50 (2/4), and 0.75 (3/4) are labeled on the ruler. Out of all the options, 0.125 is not labeled. Therefore, 0.125 is the uncertainty.

Answer:

≈ 3.91π in.

Step-by-step explanation:

IT is given that ∠APC = 92 and PB = 8 in. The arc length of AD is ≈ 3.67π in.

Arc length is defined as the distance between two points along a section of a curve.

IT is given that

∠APC = 92 and PB = 8 in

As ∠APC and ∠APD are formed in linear pairs.

So,  

∠APC + ∠APD = 180∘

∠APD = 180 -  ∠APC

∠APD = 180∘ − 92∘

∠APD = 88∘      

Now, the length of the arc will be,

= Ф/360 2πr

= 88/360 x 2 x π x 8

=88/360 x 16π

=352/90  x π

≈ 3.91π in.

Hence, the arc length of AD is ≈ 3.91π in.

#SPJ2

Answer:

a) p = 28/100    p  =  0,28      or     p  =  28%

b) SE = 0,0448

c) CI 95 %  =  ( 0.1921 ; 0.368 )

We can support with 95 % of confidence that the proportion of people with a College degree would be found within these limits

Step-by-step explanation:

a) Sample proportion:  Is the number of positive success divide by sample size

That is from 100 ( individuals) ( sample size ) it was found that 28 had College degree  ( positive success)

Then p = 28/100    p  =  0,28      or     p  =  28%

b) The standard error is

SE =  (√p*q)/n

p = 0,28   then  q =  1  -  0,28     q  =  0,72

SE =   √ (0.28)*(0.72)/100

SE =  √0.002016

SE = 0,0448

c) CI =  95 %     then  significance level is  α =  5 %    α = 0.05  

α/2 =  0.025

From z- table we find z(c)  = 1.96

Then  CI 95 %  =  p₀  ±  z(c) * SE

CI 95 %  =  0.28  ±  1.96*0.0448

CI 95 %  =  ( 0.28 ±  0.088 )

CI 95 %  =  ( 0.1921 ; 0.368 )

d) We can support with 95 % of confidence that the proportion of people with college degree would be found within these limits
