2. Amita decides that she wants the molds to have a
of the possible molds
square base. How many
can she use?

Answer:

$33.75

65%

$13.78

Step-by-step explanation:

commission earned = percentage commission x worth of goods sold

4 1/2% x $750

4.5% x $750

0.045 x $750 = $33.75

Percentage mark-up = [(selling price - cost price) / cost price] x 100

[(90.75 - 55) / 55) x 100

= 65%

new income = 6% of $13 + 13

0.06 x 13 = $0.78

$13 +  $0.78 = $13.78

Answer:

x=0, -28.

Step-by-step explanation:

abs(x+14)=14

x+14=14

x=14-14=0

----------------

x+14=-14

x=-14-14

x=-28

Answer: 19.2 ft

Step-by-step explanation:

The distance between you, Player A and Player B are in the form of a right angled triangle so using the Pythagorean Rule, we can find the distance between you and Player A.

c² = a² + b²

c = hypotenuse = Distance between you and player A

a = Length of triangle

b = Height of triangle

c² = 12² + 15²

c² = 144 + 225

c = √369

c = 19.2 ft

Answer:

Step-by-step explanation:

In statistics, about 68 percent of values come in one standard deviation of the mean by using a standard normal model.   Approximately 95% of the data were all within two standard deviations from the mean. Almost all of the data are in the range of three standard deviations of the mean (roughly 99.7%).

The 68-95-99.7 law, also known as the Empirical Rule, is based on this evidence. 68 percent of the data values of a naturally distributed data collection of small children with a mean of 8.2 and a standard deviation of 10.8 would be between -2.2 and 19.0.

Within a mean of 14.1 as well as a standard deviation of 8.2, 68 percent of the data values in a usually distributed data collection of older children would be between 5.9 and 22.3.

However, we cannot conclude that the data is naturally distributed since the real actual data vary from the usual normal curve computed above.

Hence, various measures like either goodness of fit or theory testing, would be used for this.

Answer:

[tex]\huge {\purple {a_{50} = 153}} [/tex]

Step-by-step explanation:

Given sequence is 3n + 3

[tex] \implies a_n = 3n + 3[/tex]

Plug n = 50

[tex] \implies a_{50} = 3(50) + 3[/tex]

[tex] \implies a_{50} = 150 + 3[/tex]

[tex]\huge {\red {\implies a_{50} = 153}} [/tex]

We have ,

=> T_n = a + ( n - 1)d

=> T₅₀ = 3n + 3

=> T₅₀ = 3(50) + 3

=> T₅₀ = 150 + 3

=> T₅₀ = 153

Answer:

A) H0: σ₁²-σ₂²= 0   against the claim  Ha: σ₁²-σ₂²≠0

B) t= 0.3543860

C)  t≥ t∝/2 ( d.f)=2.024394

D)1) There is no evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels.

Step-by-step explanation:

The claim is that there is evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels which is the

alternate hypothesis

The null hypothesis is the reverse of the alternate hypothesis

The null hypothesis is that there is not enough evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels.

Part A) H0: σ₁²-σ₂²= 0   against the claim  Ha: σ₁²-σ₂²≠0

Part B) t= x1`-x2`/ sqrt ( s₁²/n₁ + s₂²/n₂)

  t=  2.214- 2.0115/ sqrt ( 2.951657/20+  3.57855/20)

 t= 0.2025/ sqrt(0.14758285 + 0.1789275)

t= 0.2025/0.5714108

t= 0.3543860

Part C) for 2 tailed test the critical value of t is obtained by

t≥ t∝/2 ( d.f)= ± 2.024394

We look at the table with values 0.025 as ∝/2= 0.05/2= 0.025

in the degrees of freedom 38

The d.f = n1+n2-2= 20+20-2= 40-2= 38

Part D) Since the calculated value of t= 0.3543860 does not fall in the critical region  t≥ t∝/2 ( d.f)= ± 2.024394 we conclude that H0 is true and accept the null hypothesis.

So option 1 is correct

1) There is no evidence of a difference in the variability of the amount of time required to reach a customer service representative between the two hotels.

Answer:

Part A;

- Increases

- Increases

Part B:

- Constant but not 0

- 0

Step-by-step explanation:

Part A:

>> Looking at the speed - time graph of Airplane A, we can see that speed increases from rest at 0 seconds time to time.

>> In graph of airplane B, we can see that distance gradually increases from time at 0 to time at t1. This means that the speed is increasing.

Part B:

>> From time t1 to time t2, we see in airplane A graph that the motion is indicated a horizontal line which means there is constant motion and in constant motion, speed is constant but not zero.

>> In graph of airplane B, we see that the distance between time t1 to time t2 didn't increase. This means that there was no movement. As a result, speed will be 0

Answer:

x<26

Step-by-step explanation:

8(x/4 - 6) < 4

Divide both sides by 8;

8(x/4 - 6)/8 < 4/8

Simplify;

x/4-6<1/2

Add 6 to both sides;

x/4-6+6<1/2+6

Simplify;

x/4-6+6<1/2+6

Simplify

x/4-6+6

=x/4

Simplify;

1/2+6

Convert it into a fraction;

6*2/2+1/2

Since the denominators are equal combine the fractions;

6*2+1/2

6*2+1=13

=13/2

x/4<13/2

Multiply both sides by 4;

4x/4<13*4/2

Simplify 4x/4

4x/4

4/4=1

=x

Simplify 13*4/2

Multiply the numbers:13*4=52

=52/2

Divide the numbers:52/2=26

=26

x<26

Step-by-step explanation:

Answer:

n  =  60

Step-by-step explanation:

Terms which are divisible by 9 between 60 and 600.

63, 72, 81, ........ 594

n  =  [ (l - a)/d ] + 1

n  =  [(594 - 63)/9] + 1

n  =  (531/9) + 1

n  =  59 + 1

n  =  60

Answer:

  (i) not continuous at x=2

  (ii) -√2

Step-by-step explanation:

(i) The function simplifies to ((x -2)(x+2))/(x -2) = x +2 . . . . x ≠ 2

The left and right limits at x=2 exist and are the same: 4. However, the function is undefined at x=2, so the conditions for continuity are not met.

__

(ii) The expression is indeterminate (0/0) at x=π/4, so  L'Hopital's rule can be used to find the limit.

  lim[x→π/4] = ((d/dx)(cos(x)-sin(x)))/((d/dx)(x-π/4)) = (-sin(π/4)-cos(π/4))/1

  lim[x→π/4] = -√2/2-√2/2 = -√2

The limit is -√2.

Answer:

[tex] F)\displaystyle \: 100\pi{ x}^{8} {y}^{2} {z}^{ 6} [/tex]

Step-by-step explanation:

we are given r and the formula

we want to find the surface area of the shpare with the given r

to do so

we need our algebra skills

substitute the value of r:

[tex] \displaystyle \: S = 4\pi( {5x}^{4} y {z}^{ 3} {)}^{2} [/tex]

recall law of exponent

[tex] \displaystyle \: ({x}^{m} {)}^{n} \iff \: {x}^{mn} [/tex]

to simplify:

[tex] \displaystyle \: S = 4\pi({ {5}^{2} x}^{4 \times 2} {y}^{1 \times 2} {z}^{ 3 \times 2} )[/tex]

simplify multiplication:

[tex] \displaystyle \: S = 4\pi({ 25x}^{8} {y}^{2} {z}^{ 6} )[/tex]

distribute:

[tex] \displaystyle \: S = 100\pi{ x}^{8} {y}^{2} {z}^{ 6} [/tex]

hence our answer is F

Answer:

  x = 12

Step-by-step explanation:

An inscribed angle has half the measure of the arc it intercepts.

  arc SU +arc UT = 180°

  2(43°) +(9x -14)° = 180°

  9x = 108 . . . . . . . divide by °, subtract 72, simplify

  x = 12 . . . . . divide by 9
