Given:

10 workers produce 30 complex elements in 10 days.

To find:

The number of days, in which 5  workers produce 24 elements.

Solution:

According to the question, let as assume

[tex]n_1=10[/tex]

[tex]w_1=30[/tex]

[tex]d_1=10[/tex]

[tex]n_2=x[/tex]

[tex]w_2=24[/tex]

[tex]d_2=5[/tex]

where, n is number of workers, w is work done, and d is number of days.

We have, a formula,

[tex]\dfrac{n_1\times d_1}{w_1}=\dfrac{n_2\times d_2}{w_1}[/tex]

Substituting the values in the above formula, we get

[tex]\dfrac{10\times 10}{30}=\dfrac{x\times 5}{24}[/tex]

[tex]\dfrac{10}{3}=\dfrac{5x}{24}[/tex]

Isolate variable x.

[tex]\dfrac{10}{3}\times \dfrac{24}{5}=\dfrac{5x}{24}\times \dfrac{24}{5}[/tex]

[tex]\dfrac{240}{15}=x[/tex]

[tex]16=x[/tex]

Therefore, the required number of days is 16.

Answer:

13

Step-by-step explanation:

x = 3 & y = 5

2y + 3(x - y) + x² = 2*5 + 3(3 - 5) + 3²

                          = 2*5 + 3*(-2) + 3²

                         = 10 - 6 + 9

                        = 4 + 9

                        = 13

Answer:

15/100

Step-by-step explanation:

6 multiples of 6 between 0-40 so we find the amount 40 goes into 100, which is 2.5, then multiply 6 by 2.5 to get 15, meaning the possibility is 15%, or 15/100

Answer: 17/20

Step-by-step explanation:

There are 6 multiples of 6 in the range 1 to 40, namely 6, 12, 18, 24, 30, 36. So the probability of the speaker choosing one of these multiples is 640. Therefore, by the complement rule, the probability of not choosing a multiple of 6 is 1−640=3440. Simplify to 17/20

Answer:

x+4; all real numbers except =-4

Step-by-step explanation:

f(x)/g(x) = (x2-16)/(x+4)

The domain is all real numbers except x = -4 (because the denominator is zero at x = -4 and division by zero is undefined.)

We can simplify by factoring the numerator:

(x2-16)/(x+4) = (x-4)(x+4)/(x+4) = (x-4)

The domain is the same as the original expression: all real numbers except x = -4

Hello!

First off, what is inductive and deductive reasoning?

Inductive is when you infer off of your observations. For example, "the last three cars I passed by were white, therefore the next car will also be white". The inductive reasoning is usually a broad guess. This could be right, but it isn't factual.

Deductive is when you infer based off of facts, or confirmed information. For example, "If you get 60% on a quiz, you pa$s the quiz. John got 80% percent on his quiz, therefore he passed." It is a confirmed fact that 60% is the pas$ing grade so if John got a 80%, that is more than 60% and he passes.

I hope the examples made sense!

Step-by-step explanation:

Answer:

Step-by-step explanation:

Step one:

given data

we are told that Terry's base salary is $2100  per month.

in addition 5% on sales greater than $40000.

let the monthly salary be M(s)

and let "s" be the amount of sales made

his monthly commission =0.05s

Step two:

The expression for his monthly earning is given as

M(s)=0.05s+2100   where s>40000

 hence for a month when s=42000

M(s)=0.05(42000)+2100

M(s)=2100+2100

M(s)=4200

Therefore for an instance when s=42000 his earnings  for the month will be $4200

Answer:

Point of intersection of WY and ZX is (3.5, 3.5).

Step-by-step explanation:

Since, diagonals of a parallelogram bisect each other,

Point of intersection of the diagonals will be midpoint of each diagonal.

By this property, midpoint (x, y) of the segment joining W(-2, 6) and Y(9, 1) will be,

[tex]x=\frac{x_1+x_2}{2}[/tex]

x = [tex]\frac{-2+9}{2}[/tex] = 3.5

Similarly, y-coordinate of the midpoint will be,

y = [tex]\frac{y_1+y_2}{2}[/tex]

y = [tex]\frac{6+1}{2}[/tex] = 3.5

Therefore, point of intersection of the diagonals of the given parallelogram will be (3.5, 3.5).

Answer:

Test statistic Z= 1.713

The calculated Z- value =  1.7130 < 2.576 at 0.01 level of significance

Null hypothesis is accepted

There is no difference between the  mean annual salary of all lawyers in a city is  different from $110,000

Step-by-step explanation:

Step(i):-

A researcher wants to test if the mean annual salary of all lawyers in a city is

different from $110,000

Mean of the Population  μ = $110,000

Sample size 'n' = 53

Mean of the sample x⁻ = $114,000.

standard deviation of the Population = $17,000,

Level of significance = 0.01

Null hypothesis :

There is no difference between the  mean annual salary of all lawyers in a city is  different from $110,000

H₀:  x⁻ =  μ

Alternative Hypothesis :  x⁻ ≠  μ

Step(ii):-

Test statistic

                 [tex]Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]

                 [tex]Z = \frac{114000-110000}{\frac{17000}{\sqrt{53} } }[/tex]

                Z =  1.7130

Tabulated value Z = 2.576 at 0.01 level of significance

The calculated Z- value =  1.7130 < 2.576 at 0.01 level of significance

Null hypothesis is accepted

There is no difference between the  mean annual salary of all lawyers in a city is  different from $110,000

✎ Set up an equation and solve for x :

Add the like terms. Remember that Only coefficients of like terms can be added or subtracted.

➺ [tex] \sf{3x \degree + 90 \degree = 180 \degree}[/tex]

Move 90° to right hand side and change it's sign

Answer:

a

The 95% confidence interval is   [tex]0.5753<  p <0.62474[/tex]  

b

 This 95% confidence interval tell us that there 95% confidence that the true proportion of adults in the US that now believe life imprisonment is a better approach for punishing murder lies within the interval

c

 The margin of error is   [tex]E =    0.02474 [/tex]  

d

 The confidence interval becomes wider

Step-by-step explanation:

From the question we are told that

   The sample size is  n = 1506

    The sample proportion is  [tex]\^ p = 0.60[/tex]

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as  

     [tex]E =  Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]

=>   [tex]E =    1.96 * \sqrt{\frac{0.60 (1- 0.60)}{1506} } [/tex]    

=>   [tex]E =    0.02474 [/tex]  

Generally 95% confidence interval is mathematically represented as  

      [tex]\^ p -E <  p <  \^ p +E[/tex]

=>   [tex]0.60 - 0.02474 <  p <0.60 + 0.02474[/tex]  

=>   [tex]0.5753<  p <0.62474[/tex]  

This 95% confidence interval tell us that there 95% confidence that the true proportion of adults in the US that now believe life imprisonment is a better approach for punishing murder lies within the interval

Generally the level of confidence varies directly with the critical value of [tex]\frac{\alpha }{2}[/tex] and this in turn varies directly with the margin of error which when sample proportion is constant it determines the width of the confidence interval so when the level of confidence increases the confidence interval becomes wider  

Answer:

140

Explanation:

an=-12+4(n-2)

an=-12+4([40]-2)

an=-12+4(38)

an=-152-12

an=140

The 40th term in the sequence defined by aₙ= -12+4(n-2) is 140

using AP formula,

aₙ = a + (n - 1)d

where

a = first term

d = common difference

n = number of terms

Therefore,

aₙ = -12 + 4(n-2)

n = 40

a₄₀ = -12 + 4(40 - 2)

a₄₀ = -12 + 4(38)

a₄₀ = -12 + 152

a₄₀ = 140

The 40th term of the sequence is 140.

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Let x as that number ,

So :

[tex] \frac{50}{100} x = 60 \\ [/tex]

[tex] \frac{1}{2} x = 60 \\ [/tex]

Multiply sides by 2

[tex]2 \times \frac{1}{2} x = 2 \times 60 \\ [/tex]

[tex]x = 120[/tex]
