Answer:

This is  a reasonable decision because the sample size has no effect on the 90% confidence interval

Step-by-step explanation:

90% confidence interval

larger sample size = 20

condition : sample mean ( x-bar ) is the same for both samples

This is  a reasonable decision because the sample size has no effect on the 90% confidence interval

from condition 1 :

Amount of drink dispensed is normally distributed with known standard deviation , given a random sample of n drinks and the sample mean at a confidence interval of 90%

for condition 2 :

sample size = 20

mean = 2.25 ( assumed value )

std = 0.15 ( assumed value )

Z = 1.645 ( Z-value )

determine the 90% confidence interval

= mean ± z [tex]\frac{std}{\sqrt{n} }[/tex]

= 2.25 ± 1.645 [tex]\frac{0.15}{\sqrt{20} }[/tex]

= 2.25 ± 0.0335 = ( 2.2835 , 2.2165 )

Step-by-step explanation:

Answer:

x = 11.2

Step-by-step explanation:

Since, ΔPQR ~ ΔVST,

By the property of similar triangles, corresponding sides of these triangle will be proportional.

[tex]\frac{PQ}{VS}=\frac{QR}{ST}[/tex] ---------(1)

Since, scale factor = [tex]\frac{\text{Dimension of the image figure}}{\text{Dimension of the original}}[/tex]

[tex]\frac{2}{5}[/tex] = [tex]\frac{PQ}{VS}[/tex]

Therefore, from equation (1)

[tex]\frac{2}{5}=\frac{x}{28}[/tex]

x = [tex]\frac{28\times 2}{5}[/tex]

x = 11.2

C:18x1=1x18

when multiplying 2 numbers, the result is the same in either order.

Answer:

a = 42 b = 21

Step-by-step explanation:

a is 42 since it ks vertically opposite 42

To solve for b

360 - (42×2)........to get the angle next to a

=276... Divde answer by 2. Bc there are two of the angles

276÷2 =138

138 + 2b =180

2b = 180 - 138

b = 42 ÷ 2

b = 21

Answer:

50π cm²

Step-by-step explanation:

Lateral surface area of a cylinder is the area surrounding curved surface of the cylinder

Thus:

Lateral surface area of the cylinder = 2πrh

Where,

r = 5 cm

h = 5 cm

Plug in the values

Lateral Surface Area = 2*π*5*5

= 50π cm²

Answer:

The graph =

Step-by-step explanation:

(a)

distance covered (y) = 174 miles

time taken (x) = 3 hours

Therefore the points = (3, 174) and (0, 0) = stationary position

Find the gradient (m)

m = 174-0 / 3-0

m = 58

Therefore the equation =

(distance = 58 × time)

For the distance = 174 and time = 3 hours, the equation to find either distance or time = y = 58x

(b) the graph is constant, because the time and distance are also contant when the speed used is the same.

Answer:

D.

Step-by-step explanation:

The line goes through those points

The polynomail that represents the graph will be g(x) = (x + 4)(x + 2)(x - 4). Then the correct option is D.

Let a, b, c, and d are the zeroes of the polynomial.

Then the polynomial is given as,

⇒ (x - a)(x - b)(x - c)(x - d)

The degree of the polynomial will be greater than or equal to the number of zeroes.

The zeroes of the function are -4, -2, and 4. Then the factor of the equation is given below.

x = - 4

x + 4 = 0

x = -2

x + 2 = 0

x = 4

x - 4 = 0

Then the polynomial is given below.

g(x) = (x + 4)(x + 2)(x - 4)

The polynomail that addresses the chart will be g(x) = (x + 4)(x + 2)(x - 4). Then the right choice is D.

Answer:

[tex]NO= 31.2[/tex]

Step-by-step explanation:

See attachment for triangle

From the attachment, we have:

[tex]KL = 51.6[/tex]

[tex]LM= 38[/tex]

[tex]OP = 23[/tex]

Required

Find NO

This will be calculated using the following equivalent ratios:

[tex]NO : OP = KL : LM[/tex]

This gives:

[tex]NO : 23= 51.6: 38[/tex]

Express as fraction

[tex]\frac{NO }{ 23}= \frac{51.6}{ 38}[/tex]

Make NO the subject

[tex]NO= \frac{51.6}{ 38} * 23[/tex]

[tex]NO= \frac{51.6* 23}{ 38}[/tex]

[tex]NO= \frac{1186.8}{ 38}[/tex]

Answer: letter d

Step-by-step explanation:

Answer:

Ball D. Among the four balls in this picture, ball D is the only one whose kinetic energy is greater than [tex]0[/tex].

Step-by-step explanation:

Consider an object of mass [tex]m[/tex]. If this object is moving at a speed of [tex]v[/tex], the kinetic energy of this object would be:

[tex]\displaystyle \frac{1}{2}\, m \cdot v^{2}[/tex].

The speed [tex]v[/tex] of ball A, B, and C are all [tex]0[/tex].  Hence, the kinetic energy of these three balls would be [tex]0\![/tex].

The speed of ball D is greater than [tex]0[/tex]: [tex]v = 2\; \rm m \cdot s^{-1}[/tex]. The kinetic energy of this ball would be:

[tex]\begin{aligned} {\rm KE} &= \frac{1}{2}\, m \cdot v^{2} \\ &= \frac{1}{2}\times \rm 0.43\; \rm kg \times \left(2\; \rm m \cdot s^{-1}\right)^{2}\\ &= 0.86\; \rm J\end{aligned}[/tex].

Hence, the kinetic energy of ball D is the greatest among the four balls in this picture.
