Answer:

y=4

Step-by-step explanation:

Answer:

I think that its C

Step-by-step explanation:

I think it might be c because the two smaller(11,7) sides must add up to be longer than the longest side(18).And it would be the same length as the longest side,which means you wont be able to construct the triangle. (Eh my explanation wasnt that good but it is what it is)

Answer:

the answer I would say is ether B or C

Answer:

radius r = 3 cm

height h = 10 cm

volume V = 282.743339 cm^3

lateral surface area L = 188.495559 cm^2

top surface area T = 28.2743339 cm^2

base surface area B = 28.2743339 cm^2

total surface area A = 245.044227 cm^2

In Terms of Pi π

volume V = 90 π cm3

lateral surface area L = 60 π cm^2

top surface area T = 9 π cm^2

base surface area B = 9 π cm^2

total surface area A = 78 π cm^2

Step-by-step explanation:

Agenda:

r = radius

h = height

V = volume

L = lateral surface area

T = top surface area

B = base surface area

A = total surface area

π = pi = 3.1415926535898

√ = square root

Formluas:

Cylinder Formulas in terms of r and h:

Calculate volume of a cylinder:

V = πr2h

Calculate the lateral surface area of a cylinder (just the curved outside)**:

L = 2πrh

Calculate the top and bottom surface area of a cylinder (2 circles):

T = B = πr2

Total surface area of a closed cylinder is:

A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

Answer:

200 action figures

Step-by-step explanation:

Given

[tex]Wall = 82[/tex]

[tex]Display\ Case = 59\%[/tex]

Required

Total action films

If 59% is on a display case, then 4!% is on the wall. Let the total be x.

So, we have:

[tex]Wall = 41\% * x[/tex]

Substitute 82 for Wall

[tex]82= 41\% * x[/tex]

[tex]82= 0.41 * x[/tex]

[tex]200= x[/tex]

[tex]x = 200[/tex]

Answer:

The 95% confidence interval estimate of the true population proportion is (0.5249, 0.7151).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

From a simple random sample of 100 customers, 62 returned within 1 year after receiving the voucher.

This means that [tex]n = 100, \pi = \frac{62}{100} = 0.62[/tex]

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.62 - 1.96\sqrt{\frac{0.62*0.38}{100}} = 0.5249[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.62 + 1.96\sqrt{\frac{0.62*0.38}{100}} = 0.7151[/tex]

The 95% confidence interval estimate of the true population proportion is (0.5249, 0.7151).

No, product means multiplication, and the student wrote a division expression.

D

Step-by-step explanation:

Answer:

area of parallelogram is bh= 4.8

b= 24/25= .96ft

Answer:

24

Step-by-step explanation:

75% of x = 18

75/100 * x = 18 (x =  total number of students)

solving

x = 24

total number of students = 24

Checking:

75/100 * 24 = 18

Answer:

[tex]Area = 8\ unit^2[/tex]

Step-by-step explanation:

Given

The 7 * 3 grid

Required

Determine the area of the shaded

From the grid, 4 cells on 2 rows were shaded.

Since 1 grid cell = 1 unit.

The area is:

[tex]Area = 4\ unit * 2\ unit[/tex]

[tex]Area = 8\ unit^2[/tex]

Answer:just do 23 minus 6 and that should be the answer because the y-ccordinate is in the same place

Step-by-step explanation:

Answer: just do 23 minus 6 and that should be the answer because the y-ccordinate is in the same place

Step-by-step explanation:

Answer:  x=2  y=152

Step-by-step explanation:

9x + 10 = 15x - 2   They are  corresponding angles.

       9x = 15x - 12    [Subtract 10 from the both side]

      -6x = -12           [Subtract 15x from both side]

         x = 2             [Divide -6 from both side]

(9x + 10) + y = 180  

[9(2) + 10] + y = 180

    28 + y =   180

            y = 152

Answer:

Step-by-step explanation:

x + (180-140) + (180-132) = 180

x = 92°

Answer:

see below

Step-by-step explanation:

9/10

To get as a fraction over 100, multiply the top and bottom by 10

9*10           90

------    = ------------

10*10          100

9/10   = 90/100

The decimal form for 9/10  is .9  and for 90/100 is .90

Answer:

Haley completed 11/12 and has yet to finish 1/12 of her homework.

Step-by-step explanation:

[tex]\frac{8}{12} + \frac{3}{12} = \frac{8 + 3}{12} = \frac{11}{12}[/tex]

Haley completed 11/12 of her homework.  To find how much she has left is simple subtraction:

[tex]\frac{12}{12} - \frac{11}{12} = \frac{1}{12}[/tex]

So Haley has 1/12 of her homework left to complete.

Answer:

37.7in²

Step-by-step explanation:

(Assuming the paper goes around the side of the tin only and not the top/bottom)

Imagine the net of this can. It is a cylinder, so it would consist of a rectangle and two circles, the surface area of this rectangle is what we're being asked for.

The length and width of the rectangle are needed to find the area, (area of a rectangle=length*width). The width is marked as 3in. The length is equal to the circumference of the circle (with radius 2in):

Circumference=2πr

=2π(2)

=12.5663706144=length

Area=width*length

=3*12.5663706144

=37.6991118431

≈37.7in²

Answer:

d. Approximate the standard normal distribution with the Student's t distribution

(0.2199 ; 0.2327)

Step-by-step explanation:

Given that :

Sample size, n = 31

Sample mean, xbar = 0.2258

Sample standard deviation, s = 0.0188

Confidence interval (C. I) :

xbar ± margin of error

Margin of Error : Tcritical * s/sqrt(n)

Degree of freedom, df = n - 1 = 31 - 1 = 30

Tcritical value :

T0.05/2, 30 = 2.042

Margin of Error = 2.042 * 0.0188/sqrt(31)

Margin of Error = 0.0068949

C. I = 0.2258 ± 0.0068949

Lower boundary : (0.2258 - 0.006895) = 0.2189

Upper boundary : (0.2258 - 0.006895) = 0.2327

(0.2199 ; 0.2327)
