Answer:

The 32 electricians will take 1 day and 3 hours to complete the wiring.

Step-by-step explanation:

Since it takes electricians 36 days to wire a new housing subdivision, to determine how many days would 32 electricians take to do the same job the following calculation must be performed:

36/32 = X

1.125 = X

1 = 24

0.125 = X

0.125 x 24 = X

3 = X

Therefore, the 32 electricians will take 1 day and 3 hours to complete the wiring.

Answer:

It's about 962.89 cm^2

Answer:

962.89cm^2

Step-by-step explanation:

So, in this question, you have to find the radius of the circle because the area of a circle = πr^2. So first, you find r^2, and to do that, you divide 110 by π and you get 35.0140874802, now divide that by two and you get 17.5070437401 and that is your radius. Now, you do 17.5070437401 to the power of 2 (17.5070437401^2) and you get 306.496580518. Now multiply that by π and you get 962.89.

The length of AE¯¯¯¯¯ is 5√2 cm.

Since quadrilateral ABCD is a square, all four sides are congruent. Let's denote the length of one side as s. Therefore, the length of BD¯¯¯¯¯ is equal to s.

Given that the length of BD¯¯¯¯¯ is 10 cm, we can conclude that s = 10 cm.

Now, we need to find the length of AE¯¯¯¯¯. Looking at the square, AE¯¯¯¯¯ is the diagonal connecting opposite corners.

In a square, the diagonal divides the square into two congruent right triangles. We can use the Pythagorean theorem to find the length of the diagonal.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

In this case, the diagonal (the hypotenuse) is the same as the side length, s.

Applying the Pythagorean theorem:

s^2 = AE¯¯¯¯¯^2 + AE¯¯¯¯¯^2

10^2 = AE¯¯¯¯¯^2 + AE¯¯¯¯¯^2

100 = 2 * AE¯¯¯¯¯^2

AE¯¯¯¯¯^2 = 50

Taking the square root of both sides:

AE¯¯¯¯¯ = √50

Simplifying the square root:

AE¯¯¯¯¯ = √(25 * 2) = 5√2 cm

Answer:

g(x) = 1/2x + 7

Step-by-step explanation:

gf (x) = 3x + 8

f(x) = 6x + 2

Now  1/2 *( 6x + 2)  + 7

= 3x + 1 + 7

= 3x + 8,

so g(x) = 1/2x + 7.

Solution

We have the following equation:

2x +3 = -3x-12

We can solve for x on this way:

5x = -12-3

5x = -15

Dividing both sides by 5 we got:

x= -3

The formula for the z-statistic is (x - μ) / (σm) or (x - μ) / (s/√n) depending on known or unknown population standard deviation.

The formula for the z-statistic, which is used in hypothesis testing for a sample mean when the population standard deviation is known, is:

z = (x - μ) / (σm)

where x is the sample mean, μ is the population mean, and σm is the standard error of the mean (SEM), which is the standard deviation of the sampling distribution of the mean.

Alternatively, we can use the estimated standard error of the mean (s/√n) when the population standard deviation is unknown, and the formula for the z-statistic becomes:

z = (x - μ) / (s/√n)

where s is the sample standard deviation and n is the sample size.

What is ratio?

In mathematics, ratios indicate the number of times one number contains another number. For example, if you have 8 oranges and 6 lemons in your fruit bowl, the ratio of oranges to lemons is 8 to 6 (that is, a ratio of 8:6, or 4:3). Similarly, the ratio of lemons to oranges is 6:8 (or 3:4) and the ratio of oranges to whole fruit is 8:14 (or 4:7).

A ratio number can be any kind of quantity, such as the number of people or things, length, weight, or time. In most contexts, both numbers are restricted to positive values.

Answer:

The value is  \(E(X) = 4 \ days\)

Step-by-step explanation:

From the question we are told that

   The mean is  \(\mu = 36^oC\)

    The standard deviation \(\sigma = 3^oC\)

Generally the probability that in June , the midday  temperature is between  

39°C and 42°C is mathematically represented as

      \(P(39 < X < 42) = P(\frac{39 - 36}{3} < \frac{X - \mu }{\sigma} < (\frac{42 - 36}{3} )\)

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

      \(P(39 < X < 42) = P(1 < Z <2 )\)

=>   \(P(39 < X < 42) = P(Z < 2) - P( Z <1 )\)

From the z table  the area under the normal curve to the left corresponding to  1 and  2  is

     P(Z   < 2)  = 0.97725

and

    P(Z   < 1)  = 0.84134

    \(P(39 < X < 42) = 0.97725 - 0.84134\)

=>  \(P(39 < X < 42) = 0.13591\)

Generally number of days in June would you expect the midday temperature to be between 39°C and 42°C

      \(E(X) = n * P(39 < X 42 )\)

Here n is the number of days in June which is  n = 30

       \(E(X) = 30 * 0.13591\)

therefore, the answer is 12828648 deliveries /week​

Answer:

50%

Step-by-step explanation:

In this case we have to know the relationship between the rectangle and the triangle. The way to find out is through the areas, we know that:

The area of the rectangle = b * h

The area of the triangle = b * h / 2

If we divide, we would have:

(b * h / 2) / b * h = 1/2 = 0.5

That is, if the base and the height were equal, the probability would be 50%, if they are different, we would have to replace the values and thus find the probability.

Answer:

i. 33.51 cm³

ii. 14.14 cm³

iii. 231.61 g

Step-by-step explanation:

(i) the total volume of the paper weight,

Since the paper weight is in the form of a cone, its volume is the volume of a cone V = πD²h/12 where D = diameter of cone = 4 cm and h = height of cone = 8 cm

So, V = πD²h/12

V = π(4 cm)² × 8 cm/12

V = 16π cm² × 8 cm/12

V = 128π cm³/12

V = 402.124 cm³/12

V = 33.51 cm³

(ii) the volume of the wooden portion,

The volume of the wooden portion, V' = πr'²h'/3 where r' = radius of wooden portion and h' = height of wooden portion

From similar triangles in the figure, we have

height of wooden portion, h'/radius of wooden portion, r' = height of paper weight, h/radius of paper weight, r

h'/r' = h/r where r = D/2 where D =diameter of paper weight = 4 cm. So, r = 4 cm/2 = 2 cm

and h' = height of paper weight - height of lead portion = 8 cm - 2 cm = 6 cm

So,

r' = rh'/h = 2 cm × 6 cm/8 cm = 12 cm²/8 cm = 1.5 cm

So, V' = πr'²h'/3

V' = π(1.5 cm)² × 6 cm/3

V' = π2.25 cm² × 2 cm

V' = 4.5π cm³

V' = 14.14 cm³

(iii) the total mass of the paper weight.

The total mass of paper weight, m = mass of wooden portion + mass of lead portion = ρ'V' + ρ"V" where ρ' = density of wood = 0.9 g/cm³, V' = volume of wooden portion = , ρ" = density of lead = 11.3 g/cm³ and V" = volume of lead portion = V - V' = 33.51 cm³ - 14.14 cm³ = 19.37 cm³

So, m = 0.9 g/cm³ × 14.14 cm³ + 11.3 g/cm³ × 19.37 cm³

m = 12.726 g + 218.881 g

m = 231.607

m ≅ 231.61 g

The solved inverse matrices.

(9x - 2y = 12

3x + 4y = 18

([2],[3 ])

To solve a system of linear equations using inverse matrices, we can express the system in matrix form as follows:

[9 -2] [x] = [12]

[3 4] [y] [18]

Then we can find the inverse of the coefficient matrix, which is the matrix containing the coefficients of the variables in the system:

[9 -2]^⁻¹ = 1/((9)(4) - (-2)(3)) * [ 4 2]

[3 4] [ -3 9]

= 1/14 * [ 4 2] = [2/7  1/7]

[ -3 9] [-3/7  2/7]

We can then multiply both sides of the equation by the inverse matrix to obtain the solution:

[2/7   1/7] [9 -2] [x] = [2/7   1/7] [12]

[-3/7   2/7] [3 4] [y] [-3/7   2/7] [18]

[x] = [2/7   1/7]^-1 [2/7   1/7] [9  -2] [x]

[y] [-3/7   2/7] [-3/7    2/7] [3   4] [y]

[x] = [1  0] [9  -2] [x]

[y] [0  1] [3  4] [y]

This simplifies to the following system of equations:

9x - 2y = 12

3x + 4y = 18

Therefore in solving this system, we find that x = 2 and y = 3. So, the solution to the original system is (x, y) = (2, 3).

15=a(16.5)^2

a=0.055

So, to get depth at 4 ft from edge, I assume my new x value is 12.5.

Derived from 16.5 - 4 = 12.5

So:

y= 0.055 * (12.5)^2

Detailed explanation:

Here we need to find both the circumference and the area of a circle whose diameter is 30 in.

                                   ⚜  Circumference ⚜

This is the formula that we use for the circumference. \(\large\texttt{$C=\pi d$}\).

Here, C is the circumference,

\(\pi\) is pi, *

d is the diameter

_____________

* The number pi is an irrational number. This means that no matter how hard we try, we cannot write this number as a fraction. The reason for that is: The number pi has never-ending digits after its decimal point.

To avoid getting never-ending numbers, we will use 3.14 for pi.

_____________

Alright, so now we just stick in the values.

\(\boldsymbol{C=3.14\cdot30}\)

\(\boldsymbol{C=94.2\:inches}\)

The circumference is successfully calculated.

///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\////\\\\///\\\///\\\///\\\//\\//\/\/\/\//\///\\//

                                            ⚜ Area ⚜

This is the formula we will use to work out the area.

\(---\mapsto\boldsymbol{A=\pi r^2}\)

Here,

A denotes the area

\(\pi\) denotes pi

r denotes the radius (30/2=15, because the diameter is always two times the radius)

\(\large\boldsymbol{\therefore,\;the\;radius\;is\;15}\)

Once again, it's just a matter of sticking in the values.

\(---\mapsto\boldsymbol{A=3.14\cdot15^2}\)

Remember the Order of Operations!

P.E.M.D.A.S.

P=Parentheses

This operation tells us to evaluate all expressions in the parentheses first, if any are present.

E=Exponents

This one tells us to evaluate all expressions with exponents, if any are present.

M=Multiplication | D=Division

Unlike the two operations above, these two are completely interchangeable.

A=Addition | S=Subtraction

Like M and D, A and S are interchangeable.

_________________

Now let's simplify... According to P.E.M.D.A.S., we should square 15 first.

\(---\mapsto\boldsymbol{A=3.14\cdot225}\)

Now, we need to multiply.

\(---\mapsto\boldsymbol{A=706.5\;square\;inches}\)
