In the data set below, what are the lower quartile, the median, and the upper quartile. 13, 16, 16, 17, 51, 57, 62, 72, 92, 97

Answer: 2/5 of an hour

Step-by-step explanation:

ok so 5/8 = .625 just to begin with...

and as a ratio it would be .625 = .25

                                            8/8 (1)    

So I did .25x1=.25

.25x.625= 0.4 or as a fraction 2/5

Answer:

the volume of the sphere is 507.78981 cm^3

Step-by-step explanation:

The computation of the volume of the sphere is given below:

Given that

The Diameter is 9.9 cm

So, the volume of the sphere is

= 4 ÷ 3 ×π × r^3

= 4 ÷ 3 × 3.14 × 9.9 ÷ 2^3

= 4 ÷ 3 × 3.14 × 4.95^3

= 507.78981 cm^3

Here r denotes the radius

And, the radius would be comes by dividing the diameter from 2

Hence, the volume of the sphere is 507.78981 cm^3

Answer:

Step-by-step explanation:

A) WX=YX

angle w =angle Y=70

X=180-2x70= 40

B) all sides are equal. Angle V=T=U=180/3=60

(a) the given triangle is a isosceles triangle. The two base (non-congruent side) angles (in this case, ∠XYW & ∠XWY) will have the same measurements.

It is given that m∠XYW = 70°, therefore, m∠XWY is also 70°.

Subtract 180 from the two 70° to get m∠X:

180 - (70 + 70) = 180 - 140 = 40°

m∠X = 40° is your answer.

~

The given triangle is a equilateral triangle (All sides are congruent). If all sides are congruent, it is a equilateral triangle, and if it is a equilateral triangle, then all measurements of the inside angles are the same, 60°

m∠V = 60°

Answer:

C. $45

Step-by-step explanation:

If 2 pounds of coffee costs $17.95, we divide this number by two to get the cost of one pound of coffee.

This value is equal to $8.975 and we multiply this number by 5 to get 5 pounds of coffee.

This is about equal to option C. $45

Answer:

80 degrees

Step-by-step explanation:

The only given angle here is angle 4, which measures 100 degrees.

1) Identify angle relationships

Angle 4 and angle 6 are interior angles, meaning they have a sum of 180 degrees.

2) Solve for angle 6

180-Angle 4=Angle 6

180-100=Angle 6

80=Angle 6

Therefore, the measure of angle 6 is 80 degrees.

I hope this helps!

Answer:

c. 80°

Step-by-step explanation:

We are given a shape with a bunch of lines, and are asked to find what measure is ∠6.

Solving this is simple, we just need to keep notice that what angle is larger than 90 degrees looks like and what under 90 degrees looks like. All angles that are above 90 look wide and huge, while all under is very tiny and skinny.

If we take a look at our hint, angle 4 has the (100 degrees). Look at how wide it is, if angle 6 is tinier than that, then the answers A. and B. are scratched out.

Now 90 degrees is a right angle, looking at angle 6 guarantees that D. is also not correct because it is not a right angle.

Leaving us with C. 80

Step-by-step explanation:

Answer:

40units²

Step-by-step explanation:

find the shapes you know the formula of. There's two shapes a rectangle and a trapezoid.

do the formula for rectangle

A = bh

A = 8×2

A = 16

Now the formula for Trapezoid

A = 1/2h(b+b)

A = 1/2×4(4+8)

A = 1/2×4(12)

A = 1/2(48)

A = 24

16+24 = 40

You can discover this by doing 27 divided by . 90 which equals 30

The probability that Luca will win Wheel of Letters for this considered case is 6/13

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}}[/tex]

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

For this case, the sample space of result of wheel of letters spin is

S = {A, B, ..., Z} , thus, n(S) = size of S = 26

Let E = event that the spinner will stop in one of the letters in  “COUNTRY PHRASE”

Then, the outcomes in favor of E are {'P', 'O', 'C', 'A', 'T', 'R', 'Y', 'N', 'H', 'S', 'U', 'E'}

Thus, n(Favorable cases for E) = 12 (counted unique ones, and not repeated), as each letter is only 1 time in the spinner.

Thus, we get:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{12}{26} =\dfrac{6}{13}[/tex]

Thus, the probability that Luca will win Wheel of Letters for this considered case is 6/13

Answer:

70,176

Step-by-step explanation:

Given that

482 - 412 + 286 - 12 × 204

We need to solve the above equation

= 482 - 412 + 286 - 12 × 204

= 70 + 286 - 12 × 204

= 356 - 12 × 204

= 344 × 204

= 70,176

Hence, the answer to the given equation is 70,176

Answer:

Part A:

A,C

Part B:

B,C

Answer:

B.

Step-by-step explanation:

The answer is B because 3/5 of 1/2 is less than 1/2. The equation that represents this problem is

3/5 x 1/2 = 3/10

3/10 < 1/2

Therefore, 3/5 is less than 1/2!

Answer:

w = 325cm

Step-by-step explanation:

=> here's your solution

=> formula is v = t*w*h

=> v = 5915cm^3

=> t = 91cm

=> we need to find w = ?

=> V = T*W*H

=> w = 5915/(91*5)

=> w = 325cm

Answer:

Answer:

99% C.I of the population mean is ( 11746, 11800 )

Step-by-step explanation:

Given the data in the question;

Sample size n = 9

mean x" = 11773  

standard deviation s = 24

for 99% confidence interval

∝ = 1 - 99% = 1 - 0.99 = 0.01

∝/2 = 0.01/2 = 0.005

degree of freedom df = n - 1 = 9 - 1 = 8

now, Critical t-value : [tex]t_{\alpha /2, df[/tex] =  [tex]t_{0.005, 8[/tex] = 3.355

Now, at 99% Confidence interval of the mean population is;

x" ± [ [tex]t_{\alpha /2, df[/tex] × s/√n ]

we substitute

11773  ± [ 3.355  × 24/√9 ]

11773   ± [ 3.355  × 8 ]

11773 ± 26.84

so

⇒ {11773 - 26.84}, {11773 + 26.84}

⇒ ( 11746, 11800 )

Therefore, 99% C.I of the population mean is ( 11746, 11800 )

The the tangent of the angle is ...

  tan(θ) = √(sec²(θ) -1)

  tan(θ) = √((5/3)² -1) = √(16/9)

  tan(θ) = 4/3

Answer:

(1.307 ; 3.893)

Step-by-step explanation:

Given that:

Mean, xbar = 2.6

Standard deviation, s = 0.69

Sample size, n = 5

Confidence interval : xbar ± margin of error

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

Degree of freedom (df) = n - 1 = 5 - 1 = 4

Hence Tcritical = 3.747

Margin of Error = 3.747 * 0.69/sqrt(4)

Margin of Error = 1.293

Lower boundary = (2.6 - 1.293) = 1.307

Upper boundary = (2.6 + 1.293) = 3.893

(1.307 ; 3.893)
