Answer:

7 square root 9^4

Step-by-step explanation:

Answer:

[tex]Mean = 100[/tex]

[tex]Median = 96[/tex]

Step-by-step explanation:

Given

[tex]C_v = 30\%[/tex] --- coefficient of variation

[tex]mode = 88[/tex]

[tex]Skp = 0.4[/tex]

Required

The mean and the median

The coefficient of variation is calculated using:

[tex]C_v = \frac{\sigma}{\mu}[/tex]

Where:

[tex]\mu \to[/tex] mean

So:

[tex]30\% = \frac{\sigma}{\mu}[/tex]

Express percentage as decimal

[tex]0.30 = \frac{\sigma}{\mu}[/tex]

Make [tex]\sigma[/tex] the subject

[tex]\sigma = 0.30\mu[/tex]

The coefficient of skewness is calculated using:

[tex]Skp = \frac{\mu - Mode}{\sigma}[/tex]

This gives:

[tex]0.4 = \frac{\mu - 88}{\sigma}[/tex]

Make [tex]\sigma[/tex] the subject

[tex]\sigma = \frac{\mu - 88}{0.4 }[/tex]

Equate both expressions for [tex]\sigma[/tex]

[tex]0.30\mu = \frac{\mu - 88}{0.4 }[/tex]

Cross multiply

[tex]0.4*0.30\mu = \mu - 88[/tex]

[tex]0.12\mu = \mu - 88[/tex]

Collect like terms

[tex]0.12\mu - \mu = - 88[/tex]

[tex]-0.88\mu = - 88[/tex]

Divide both sides by -0.88

[tex]\mu = 100[/tex]

Hence:

[tex]Mean = 100[/tex]

Calculate [tex]\sigma[/tex]

[tex]\sigma = 0.30\mu[/tex]

[tex]\sigma = 0.30 * 100[/tex]

[tex]\sigma = 30[/tex]

So:

Also, the coefficient of skewness is calculated using:

[tex]Skp = \frac{3 * (Mean - Median)}{\sigma}[/tex]

[tex]0.4= \frac{3 * (100 - Median)}{30}[/tex]

Multiply both sides by 30

[tex]0.4*30= 3 * (100 - Median)[/tex]

Divide both sides by 3

[tex]0.4*10= 100 - Median[/tex]

[tex]4= 100 - Median[/tex]

Collect like terms

[tex]Median = 100 - 4[/tex]

[tex]Median = 96[/tex]

Answer:

The answer is "(0.727, 1.573)".

Step-by-step explanation:

The confidence interval of 98 percent is C.I = (0.727, 1.573). You might disregard the statement of the experts that the genuine average duration in California of earthquakes is 0.5 minutes.

[tex]C.I = \bar{x}\pm t_{\frac{\alpha }{2}}\times \frac{s }{\sqrt{n}}\\\\[/tex]

      [tex]= 1.15 + 3.365 \times 0.12574\\\\= 1.15 + 0.4231\\\\= (0.7269, 1.5731)[/tex]

Step-by-step explanation:

Using an online calculator, I was able to find that one pattern is

[tex]a_{n} = a_{n-1} + 14 * 3^{n-1}[/tex] . Finding a recursive sequence is generally based on guess and check, so there isn't much explanation to obtaining one

Answer:

x≤-8

Step-by-step explanation:

-1/2x ≥ 4

Multiply each side by -2, remembering to flip the inequality

-2*-1/2x≤ 4*-2

x≤-8

Answer:

Step-by-step explanation:

Note: by the rule of order of operations, -1/2x == -1/2*x = -x/2

-x/2 >= 4

-x >= 4*2 = 8

x <= -8

The number line looks like this:

Answer:

That Satisfies The Given Statement. Tan 0 = 0.78879988 (Simplify Your Answer. Type An Integer Or A Decimal.

Step-by-step explanation:

Attached you'll find the region of interest, which is captured by the set of points

R = {(x, y) | √(y/2) ≤ x ≤ (4 - y)/2 and 0 ≤ y ≤ 2}

Written in this way, it's convenient to integrate with the order dx dy (that is, with respect to x first). In particular, we have

[tex]\displaystyle\iint_R(7xy-5-2y^2)\,\mathrm dx\,\mathrm dy = \int_0^2 \int_{\sqrt{\frac y2}}^{\frac{4-y}2} (7xy-5-2y^2)\,\mathrm dx\,\mathrm dy[/tex]

[tex]\displaystyle = \int_0^2 \int_{\sqrt{\frac y2}}^{\frac{4-y}2} \left(\frac72 x^2y-5x-2xy^2\right)\bigg|_{\sqrt{\frac y2}}^{\frac{4-y}2}\,\mathrm dy[/tex]

[tex]=\displaystyle\int_0^2\left(\frac{15}8y^3-11y^2+\frac{33}2y-10 +\sqrt2 y^{\frac52}-\frac74y^2+\frac5{\sqrt2}y^{\frac12}\right)\,\mathrm dy[/tex]

[tex]=\displaystyle\left(\frac{15}{32}y^4+\frac{2\sqrt2}7y^{\frac72}-\frac{17}4y^3+\frac{33}4y^2+\frac{5\sqrt2}3y^{\frac32}-10y\right)\bigg|_0^2[/tex]

Answer:

336 square inches

Step-by-step explanation:

Nets are the spreaded out version/outline of 3d figures. It shows the faces of the figure. The figure in this case is actually a triangular prism.

find the area of each shape in the net:

Triangle A (1/2 x base x height)

1/2 • 8 x 6 = 24 square inches

Rectangle B (length x width):

6 x 12 = 72 square inches

Rectangle C:

8 x 12 = 96 square inches

Rectangle D:

10 x 12 = 120 square inches

Triangle E:

1/2 x 6 x 8 = 24 square inches

Add up all the areas of all shapes:

24 + 24 + 120 + 72 + 96 = 336

Surface area is measured in square inches

(Inches in this case)

Answer:

47

Step-by-step explanation:

1. #2 and #3 reveal that it must be between 31 to 89

2. #4 and #5 reveals that the answer is one of these numbers:

44, 45, 46, 47, 48, 49

64, 65, 66, 67, 68, 69

84, 85, 86, 87, 88, 89

This is because only 4, 6, and 8 are divisible by 2

3. You must add up all the numbers to see which ones add up to either 11 or 12.

4 + 7 = 11

4 + 8 = 12

6 + 5 = 11

6 + 6 = 12

8 + 4 = 12

This means that these are the following numbers: 47, 48, 65, 66, 84

4. #7 says that you must find the smallest number. The smallest number left is 47.

Answer:

the answer should be B, because I think the collection of fruits is right

Answer:

i think its b

Step-by-step explanation:

Rate of change = RΔ = (y2-y1)/(x2-x1) = Δy/Δx

(X1,Y1)(X2,Y2)

(1, 2) (2, 4)

RΔ = Δy/Δx

= (4-2)/(2-1)

RΔ = 2

(2, 4) (3, 8)

RΔ = (8-4)/(3-2)

RΔ = 4

(3, 8) (4, 16)

RΔ = (16-8)/(4-3)

RΔ = 8

Step-by-step explanation:

[tex]\displaystyle \lim_{x \to 0}\dfrac{\sin x}{x}[/tex]

Let

[tex]f(x)= \sin x[/tex]

[tex]g(x)=x[/tex]

We are going to use L'Hopital's Rule here that states

[tex]\displaystyle \lim_{x \to c}\dfrac{f(x)}{g(x)}=\lim_{x \to c}\dfrac{f'(x)}{g'(x)}[/tex]

We know that

[tex]f'(x) = \cos x[/tex] and [tex]g'(x)=1[/tex]

so

[tex]\displaystyle \lim_{x \to 0}\dfrac{\sin x}{x}=\lim_{x \to 0}\dfrac{\cos x}{1}=1[/tex]

Answer:

Ibrahim gets 5 fixed and 3.5 per hour.

Step-by-step explanation:

Ibrahim has a side job at the market. He calculates his income with the formula income in € = 5 + 3.50 x,  time in hours. Explain the formula.

Here, the fixed income is 5.

the income per hour is 3.5.

So, Ibrahim gets 5 fixed and 3.5 per hour.

Hello,

Part A:

[tex]f(x)=4x^2+8x-5\\=4(x^2+2x)-5\\=4(x^2+2x+1-1)-5\\=4(x+1)^2-9\\=(2(x+1)-3)(2(x+1)+3)\\=(2x-1)(2x+5)\\x-intercepts\ are\ x=\frac{1}{2} \ and\ x=-\frac{5}{2} \\[/tex]

I hope it's helpful for u but I am not sure my answer is right !

You can solve for the velocity and position functions by integrating using the fundamental theorem of calculus:

a(t) = 40 ft/s²

v(t) = v (0) + ∫₀ᵗ a(u) du

v(t) = -20 ft/s + ∫₀ᵗ (40 ft/s²) du

v(t) = -20 ft/s + (40 ft/s²) t

s(t) = s (0) + ∫₀ᵗ v(u) du

s(t) = 10 ft + ∫₀ᵗ (-20 ft/s + (40 ft/s²) u ) du

s(t) = 10 ft + (-20 ft/s) t + 1/2 (40 ft/s²) t ²

s(t) = 10 ft - (20 ft/s) t + (20 ft/s²) t ²

Answer:

The slope is 1/2 because for every y value that it goes down, the x value goes down by 2. The y-intercept is 4 because when x is 0, y is equal to 4.

$4825.70

Step-by-step explanation:

Cost for Fans: 4 x 675 = $2700

Cost for Lamps: 2 x 110 = $220

Cost for Switches: 5 x 41 = $205

Cost for Tubes: 6 x 135 = $810

Cost for Electric Wire: 230 x 2.50 = $575

Total cost: 2700 + 220 + 205 + 810 + 575 = $4510

Tax: Total cost x Tax rate = 4510 x 0.07 = $315.70

Total paid: Total cost + Tax = 4510 + 315.70 = $4825.70
