Answer: A 95% lower confidence bound for the mean capacity of this type of battery = 175.85

Step-by-step explanation:

Given: The capacities were measured for a sample : n= 120 batteries.

[tex]\overline{x}=178[/tex] and  [tex]\sigma=12[/tex]

lower confidence bound= [tex]\overline{x}-z^c\times\dfrac{\sigma}{\sqrt{n}}[/tex]

Critical z value for 9%% confidence = 1.96

So,  a 95% lower confidence bound for the mean capacity of this type of battery will be :

[tex]178-(1.96)\dfrac{12}{\sqrt{120}}\\\\=178-(1.96)(1.0954451)\\\\=(1.96)(1.0954451)\approx175.85[/tex]

Hence, a 95% lower confidence bound for the mean capacity of this type of battery = 175.85

Answer:

[tex]\huge\boxed{\text{Numbers: 3, 18}}[/tex]

Step-by-step explanation:

We can create two equations and solve the system of equations to find both the numbers. Let's represent the numbers as a and b.

We can create two equations:

[tex]a+b=21[/tex]

[tex]b=6a[/tex]

We can now substitute the value of b (6a) into the first equation.

[tex]a + (6a) = 21[/tex]

Combine like terms:

[tex]7a=21[/tex]

Divide both sides by 7:

[tex]a=3[/tex]

Now we know the first number is 3. We can plug this value into one of the equations to find b. Let's plug it into [tex]b=6a[/tex].

[tex]b = 6 \cdot 3\\\\b = 18[/tex]

So our numbers are 3 and 18.

Hope this helped!

Step-by-step explanation:

We can create two equations and solve the system of equations to find both the numbers. Let's represent the numbers as a and b.

We can create two equations:

a+b=21a+b=21

b=6ab=6a

We can now substitute the value of b (6a) into the first equation.

a + (6a) = 21a+(6a)=21

Combine like terms:

7a=217a=21

Divide both sides by 7:

a=3a=3

Now we know the first number is 3. We can plug this value into one of the equations to find b. Let's plug it into b=6ab=6a .

b=6⋅3

b=18

So our numbers are 3 and 18.

Answer:

P = - 0.1x+520

Step-by-step explanation:

Finding the demand function p ( x ) , where x is the number of the television sets sold per week.

each $25 rebate offered to the buyer, the number of sets sold will increase by 250 , hence slope = -25/250 = -1/10 Equation will be

P-390/x-1300 = -25/250

Cross multiplying

250(P-390) = -25(x-1300)

250p-97500 = -25x+32500

250p = -25x+32500+97500

250p = -25x + 130000

Divide both sides by 250

250p/250 = (25x + 130000)/250

P = - 0.1x+520

Hence, the demand function p(x) is

= - 0.1x+520

Since one yard is equivalent to three feet, you can multiply the number of yards by 3 to convert from yards to feet. 36 feet are equal to 12 yards times 3 feet per yard. Consequently, 12 yards are equal to 36 feet.

A unit of length equivalent to 3 feet, or around 0.914 metres.

Both the US Customary and British Imperial Systems of Measurement use yards as a measure of length. Yd is its symbol. The length of medium-sized objects is frequently measured using it.

About half the length of a bed is a yard. wider than a huge refrigerator. the elevation of a countertop.

Given data

number of employee= 25

number of team=3

The expression for combination is given as

C(n,r)=(nr)=n!/(r!(n−r)!)

C(25,3)=25!/(3!(25−3)!)

C(25,3)=25!/(3!(22!)

C(25,3)=25*24*23*22!/3!(22!)

C(25,3)=25*24*23*/3!

C(25,3)=25*24*23*/3*2*1

C(25,3)=25*24*23*/6

C(25,3)=13800/6

C(25,3)=2300 ways

The number of ways where a store manager arranges a group is 50,600.

Given that,

Based on the above information, the calculation is as follows:

[tex]= ^25C_4 \times 4C_1\\\\= \frac{25!}{4!(25-4)!} \times \frac{4!}{1!(4-1)!} \\\\= \frac{25!}{4! \times 21!} \times \frac{4!}{1! \times 3!} \\\\= 12,650 \times 4[/tex]

= 50,600

Therefore we can conclude that the number of ways where a store manager arranges a group is 50,600.

Answer:

33.33% or [tex]\frac{2}{6}[/tex]

Step-by-step explanation:

A single die has a total of six different possible outcomes (1, 2, 3, 4, 5, 6). Since the numbers two and five are only two of the six possible outcomes that means that the possibility of getting one of these two numbers on a single roll is [tex]\frac{2}{6}[/tex] . If we divide this fraction and multiply the result by 100 (0.333 * 100 = 33.33) we see that there is a 33.33% chance of you rolling either a two or a five.

Given: Mean [tex]\mu=9.6\text{ inches}[/tex], Standard deviation  [tex]\sigma=2.4\text{ inches}[/tex]

The probability that its diameter will fall between 7.2 inches and 14.4 inches will be:

[tex]P(7.2<X<14.4)=P(\dfrac{7.2-9.6}{2.4}<\dfrac{X-\mu}{\sigma}<\dfrac{14.4-9.6}{2.4})\\\=P(-1<Z<2)\ \ \ \ [Z=\dfrac{X-\mu}{\sigma}]\\\\=P(Z<2)-P(Z<-1)\\\\=P(Z<2)-(1-P(Z<1))\\\\=0.9772-(1-0.8413)=0.8185\ [\text{By p-value table}][/tex]

It should be noted that when Andre and Elena are solving this system of equations, the first step is correct but the others are wrong.

It should be noted that an equation is used.to show the relationship between the expressions that are given.

It should be noted that Andre and Elena are solving this system of equations: y=3x, y=9x−30.

This will be equated to this:

3x = 9x - 30

Collect like terms

9x - 3x = 30

6x = 30

Divide

x = 30 / 6

x = 5

Note that y = 3x = 3 × 5 = 15

Therefore, it should be noted that when the value of y is 15 and only the first step is correct.
