Assume that adults have IQ scores that are normally distributed with a mean of μ=105 and a standard deviation equals σ=20. Find

GuDViN [60]

Probability that a randomly selected adult has an IQ less than 137 is 0.9452

Step-by-step explanation:

Step 1:

Sketch the curve.

The probability that X<137 is equal to the blue area under the curve.

Step 2:

Since μ=105 and σ=20 we have:

P ( X<137 )=P ( X−μ<137−105 )= P(X−μ/ σ< 137−105/20 )

Since x−μ/σ=Z and 137−105/20=1.6 we have:

P (X<137)=P (Z<1.6)

Step 3:

Use the standard normal table to conclude that:

P (Z<1.6)=0.9452

∴ probability that a randomly selected adult has an IQ less than 137 is 0.9452.

A city averages 14 hours of daylight in June (the longest days) and 10 in December (the shortest days). Assume that the number o

OLga [1]

We have that the graph will have a solution that is mathematically given as

y=12sin(6t-\pi)+2

<h3>Daylight time June trough to December</h3>

Question Parameters:

A city averages 14 hours of daylight in June (the longest days) and 10 in December (the shortest days).

Generally the equation for the Amplitude and vertical shift is mathematically given as

$A=\frac{Max+min}{2}\\\\A=\frac{10+14}{2}$

A=2

vertical shift = $\frac{Max-min}{2}$

vertical shift = $\frac{14-10}{2}$

vertical shift =1

Therefore, the time is given as

$t=\frac{2\pi}{b}$

Where

$b=\pi/6\\\\t=\frac{2\pi}{\pi/6}$

Hence,The graph will have a solution

y=12sin(6t-\pi)+2

Find the equation of the sphere in standard form centered at (−6,10,5) with radius 5.

Dovator [93]

Answer:

The equation of the sphere in standard form is

$x^{2} +y^{2}+z^{2} +12 x-20 y-10 z+136=0$

Step-by-step explanation:

Step 1:-

The equation of the sphere having center and radius is

$(x-h)^{2} +(y-k)^{2} +(z-l)^{2} = r^{2}$

Given centered of the sphere is (-6,10,5) and radius r=5

$(x-(-6))^{2} +(y-10)^{2} +(z-5)^{2} = 5^{2}$

on simplification,we get

$using (a+b)^{2} =a^{2} +2 a b+b^{2}$

$using (a-b)^{2} =a^{2} -2 a b+b^{2}$

simplify , we get

$x^{2} +y^{2}+z^{2} +12 x-20 y-10 z+136=0$

2(x-5)+8=4 what does x equal?

Ostrovityanka [42]

Answer:

x=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(x−5)+8=4

(2)(x)+(2)(−5)+8=4(Distribute)

2x+−10+8=4

(2x)+(−10+8)=4(Combine Like Terms)

2x+−2=4

2x−2=4

Step 2: Add 2 to both sides.

2x−2+2=4+2

2x=6

Step 3: Divide both sides by 2.

2x/2 = 6/2

x=3
