Step-by-step explanation:

7 times 5 equals 35 plus 1 equals 36

Answer:

Option (2)

Step-by-step explanation:

If we spin spinner 1, the possible outcome on this spinner for a single spin will be either RED (R) or GREEN (G).

Similarly, if we spin spinner 2, possible outcomes for a single spine will be 1 or 2 or 3 or 4.

If we spin both the spinners possible outcomes from both the spinners in a single spin will be,

Red with 1 Or Red with 2 Or Red with 3 Or Red with 4,Or

Green with 1 Or Green with 2 Or Green with 3 Or Green with 4

Symbolically,

R1, R2, R3, R4, G1, G2, G3, G4

Therefore, Option (2) will be the answer.

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.

Answer:

x = 18°

Step-by-step explanation:

Vertical angles can be defined as a pair of angle formed when two (2) lines intersect. These angles formed during the intersection of the two (2) lines are opposite to each other.

Hence, vertical angles are always equal to one another.

From the question, we have;

58° = (3x + 4)°

Rearranging the equation;

[tex] 3x = 58 - 4[/tex]

[tex] 3x = 54[/tex]

[tex] x = \frac{54}{3}[/tex]

x = 18°

Therefore, the value of x is 18 degrees.

Answer:

Except for -1 (12w - 6).

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: 0.8185

Step-by-step explanation:

Let X represents the tree diameters that are distributed normally.

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]

Hence, required probability = 0.8185

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

Answer: y=-3

Answer:

x = -12

Step-by-step explanation:

This is a vertical line, so the equation will be of the form x = k, where k is any x-value.

The conclusion that x = -12 was found because the x-value in the point was -12.

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:

Step-by-step explanation:

in this problem, we are expected to use commination to arrive at a solution

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.

Complete Question

A population has a mean of 200 and a standard deviation of 50. Suppose a random sample of 100 people is selected from this population. What is the probability that the sample mean will be within [tex]\pm 5[/tex] of the population mean

Answer:

The value is  [tex]P(195 <  X  <  205 ) =  0.6827  [/tex]

Step-by-step explanation:

From the question we are told that  

   The mean is [tex]\mu = 200[/tex]

    The population standard deviation is  [tex]\sigma = 50[/tex]

    The sample size is  [tex]n = 100[/tex]

Generally the standard error of sample mean is mathematically represented as

       [tex]s = \frac{ \sigma }{\sqrt{n} }[/tex]  

=>    [tex]s = \frac{50 }{\sqrt{100} }[/tex]  

=>    [tex]s =5[/tex]

Generally the limits of   [tex]\pm 5[/tex]  within  the population mean is mathematically represented as

      [tex]a = \mu - 5[/tex]

=>  [tex]a = 200 - 5[/tex]

=>  [tex]a = 195[/tex]

and

    [tex]b = \mu + 5[/tex]

=>[tex]b = 200 + 5[/tex]

=>[tex]b = 205[/tex]

Generally the probability that the sample mean will be within [tex]\pm 5[/tex] of the population mean is mathematically represented as

         [tex]P(a < X < b ) = P(\frac{a - \mu }{s} < \frac{X - \mu }{s} < \frac{b - \mu }{s} )[/tex]

=>    [tex]P(195 <  X  <  205 ) =  P(\frac{ 195-  200 }{5} < \frac{X -  \mu }{s} < \frac{205 -  200 }{5}  )[/tex]

 [tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

=>    [tex]P(195 <  X  <  205 ) =  P(-1< Z<1 )[/tex]

=>    [tex]P(195 <  X  <  205 ) =  P(Z <  1)  -  P(Z<-1 )[/tex]

Generally from the  z -table  the probability of  (Z <  1) and  (Z<-1 )  is

     [tex]P(Z < 1)= 0.84134[/tex]

and  

    [tex] P(Z<-1 )   = 0.15866 [/tex]

So

      [tex]P(195 <  X  <  205 ) =  0.84134  -  0.15866  [/tex]

      [tex]P(195 <  X  <  205 ) =  0.6827  [/tex]
