Using the normal distribution, it is found that there is a 0.1029 = 10.29% probability that the sample mean is above 96.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Researching the problem on the internet, the parameters are given as follows:

[tex]\mu = 92, \sigma = 10, n = 10, s = \frac{10}{\sqrt{10}} = 3.1623[/tex]

The probability that the sample mean is above 96 is one subtracted by the p-value of Z when X = 96, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem:

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{96 - 92}{3.1623}[/tex]

Z = 1.265

Z = 1.265 has a p-value of 0.8971.

1 - 0.8971 = 0.1029 = 10.29% probability that the sample mean is above 96.

The reduced form of the trig expression is 7/2sin²2a

Trigonometry identities are written in terms of sine, cosine and tangent. Given the trigonometry identity

14sin² acos² a

Since sin(a)cos(a) = sin2a/2, hence

14sin²acos²a = 14[sin(a)cos(a)]²

14sin²acos²a = 14(sin2a/2)²

14sin²acos²a = 14/4(sin²2a)

When ratios of quantities are given, it is often convenient to consider a group of objects in which the objects have that ratio.

Here, we have 2 dimes for each quarter, so a group of 2 dimes and 1 quarter is a useful group for this problem. Its value is 2×$0.10 +0.25 = $0.45.

The total value of all of the groups is $3.60, so there must be ...

  $3.60/($0.45/group) = 8 groups

The 8 groups of coins will have 16 dimes and 8 quarters.

The graph of the parabola can be seen in the image below.

Here we have the function:

g(x) = (15x)^2

Notice that this is a contraction of scale factor 15 of the function f(x) = x^2

To graph this, we can just evaluate the function in 3 points, the vertex and two other ones.

for x = 0.

g(0) = (15*0)^2 = 0

So we have the point (0, 0).

Evaluating in x = 1 and x = -1 (give the same value) we get:

g(±1) = (±15)^2 = 225

So we have the points (1, 225) and (-1, 225).

Original Equation:

Calculate exponents

[tex]\frac{4y}{1.103812890625}+y-2y(1.1025)=1500\\[/tex]

Simplify:

[tex]3.6238025791990193084270042653997y + y - 2.205y = 1500[/tex]

Add like terms

[tex]2.4188025791990193084270042653997y \approx 1500[/tex]

Divide both sides by 7.012

[tex]y\approx 213.91[/tex][tex]y\approx620.14[/tex]

Answer:

y = $620.14 (nearest cent)

Step-by-step explanation:

Given equation:

[tex]\dfrac{4y}{1.025^4}+y-2y(1.05)^2=\$1,500[/tex]

Factor out y from the left side:

[tex]\implies y\left(\dfrac{4}{1.025^4}+1-2(1.05)^2\right)=\$1,500[/tex]

Carry out the arithmetic operations inside the parentheses by following the order of operations PEMDAS:

Calculate the exponents:

[tex]\implies y\left(\dfrac{4}{1.103812891...}+1-2(1.1025)\right)=\$1,500[/tex]

Carry out the multiplication and division from left to right:

[tex]\implies y\left(3.623802579...+1-2.205\right)=\$1,500[/tex]

Carry out the addition and subtraction from left to right:

[tex]\implies y\left(4.623802579...-2.205\right)=\$1,500[/tex]

[tex]\implies y\left(2.418802579...\right)=\$1,500[/tex]

Finally, divide both sides by the coefficient of y to isolate y:

[tex]\implies \dfrac{y\left(2.418802579...\right)}{2.418802579...}=\dfrac{\$1,500}{2.418802579...}[/tex]

[tex]\implies y=\$620.141558...[/tex]

Therefore, y = $620.14 (nearest cent)

By applying the volume formulae for composite figures, cones and hemispheres, we obtain that the volume is approximately equal to 558.9 cubic centimeters.

The volume of the composite figure is the sum of the volumes of the two figures: (i) a cone, (ii) a hemisphere. The volume formula of the figure is shown below:

[tex]V = \frac{2\pi}{3} \cdot r^{3} + \frac{\pi}{3}\cdot r^{2}\cdot h[/tex]      

If we know that r = 5.3 cm and h = 8.4 cm, then the volume of the composite figure is:

V = (2π/3) · (5.3 cm)³ + (π/3) · (5.3 cm)² · (8.4 cm)

V ≈ 558.900 cm³

The value of the house in the year 2010 is 150056.47.

The growth rate of a value (GDP, turnover, wages, etc.) measures its change from one period to another (month, quarter, year)

Value

v(t) = V0 ( 1 + r)^t

let V0 =  106, v(20) = 146

So,

146 = 110(1 + r )^20

146/110 = (1 + r )^20

1.327 = (1 + r )^20

1+ r = 1.014

r= 0.014

So, annual growth rate is 1.4%.

In the year 2010

v(t) = 106(1.014)^25

v(t) = 106(1.014)^25
