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 )

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

Step-by-step explanation:

They are both even numbers the 4 is seperated into 2,2 and if 4 is an even and event A is even it would be dependent

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: 96 cents or 0.96

Step-by-step explanation:

When in a money problem like this and it is telling you to find the tax, fee, or and bonus you move the decimal in front of the number or decimal and round to the nearest penny and in this situation .195 rounds to .96

The balance in her account at the end of 2.5 year should be considered as the $3,568.

Since deposited amount si $3,400

The interest rate is 1.95%

And, the time period is 2.5 years

So, here the balance should be like

[tex]= 3400 \times (1 + 1.95\%)^{2.5[/tex]

= $3,568

hence, The balance in her account at the end of 2.5 year should be considered as the $3,568.

Answer:

a - 129

b - 63

Step-by-step explanation:

for a - supplementary angles add up to equal 180

so to find the measure of its supplement we subtract the given angle from 180 180-51=129

so the measure of a supplement angle is 129

for b - complementary angle add up to equal 90

so to finds the measure of its complement we subtract the given angle from 90

90-27=63

so the measure of its complement is 63

Answer:

(a) An angle measures 51°. the measure of its supplement=180-51=129°

b) An angle measures 27°. the measure of its complement=90-27=63°

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:

x≈ 16.9

Step-by-step explanation:

Answer:  x=3

Step-by-step explanation; Add 5 to both sides of the equation

6x-5+5=2x+7+5

simplify: add the numbers

6x-5+5=2x+75 = 6x=2x + 7+5

6x =2x + 7+5

6x=2x +12.

subtract 2x from both ides of the equation: 6x=2x + 12

6x - 2x =2x + 12-2x6

combine like terms  u should get 4x= 12

divided both sides of the equation by the same term 4x=12  4x/4 =12/4

Cancel terms that are in both the numerator and denominator u should get  x=12/4

divided the numbers and ur answer is X=3
