A set of data has a normal distribution with a mean of 5.1 and standard deviation of 0.9. Find the percent of data between 6.0 a
jolli1 [7]

The percent data between 6.0 and 6.9 would be 13.59%. Here’s the complete solution for this specific problem.

<span>z = (X - Mean)/SD </span><span>
<span>z1 = (6 - 5.1)/09 = + 1 </span>
<span>z2 = (6.9 - 5.1)/09 = + 2 </span>
<span>Required Percent = P(6 < X < 6.9)*100 </span>
<span>= P(1 < z < 2)*100 </span>
<span>= [P(z < 2) - P(z < 1)]*100 </span>
<span>= [0.9772 - 0.8413]*100 </span>
<span>= 0.1359*100 </span>
<span>= 13.59%

I am hoping that this has answered your query.</span></span>

∆GHI is an isosceles triangle with a vertex angle H If the m∠H=80°, then find the m∠I.
Dmitriy789 [7]

Answer:

m∠I = 50 degrees

Step-by-step explanation:

Mathematically, the base angles of an isosceles triangle are equal

So in this case, since H is a vertex;

m∠I + m∠H + m∠G = 180

m∠I = m∠G = x

2x + 80 = 180

2x = 180-80

2x = 100

x = 100/2

x = 50

What are the critical points for the inequality x^2 - 4/x^2 - 5x +6 &lt; 0?
Leokris [45]

Answer:

Critical points are: 2 , -2 and 3.

Step-by-step explanation:

We have been given the expression:

\frac{x^2-4}{x^2-5x+6}

We will factorize the given expression:

Using a^2-b^2=(a+b)(a-b)

\frac{(x+2)(x-2)}{x^2-3x-2x+6}

\Rightarrow \frac{(x+2)(x-2)}{x(x-3)-2(x-3)}

\Rightarrow \frac{(x+2)(x-2)}{(x-2)(x+3)}

Critical point are those values of an expression when it is equal to zero

Hence, the critical points are: 2,-2 and -3.
