A set of middle school student heights are normally distributed with a mean of 150 centimeters and a standard deviation of 20 ce
julsineya [31]

Answer:

The proportion of students whose height are lower than Darnell's height is 71.57%

Step-by-step explanation:

The complete question is:

A set of middle school student heights are normally distributed with a mean of 150 centimeters and a standard deviation of 20 centimeters. Darnel is a middle school student with a height of 161.4cm.

What proportion of proportion of students height are lower than Darnell's height.

Answer:

We first calculate the z-score corresponding to Darnell's height using:

Z=\frac{X-\mu}{\sigma}

We substitute x=161.4 , \mu=150, and \sigma=20 to get:

Z=\frac{161.4-150}{20} \\Z=0.57

From the normal distribution table, we read 0.5 under 7.

The corresponding area is 0.7157

Therefore the proportion of students whose height are lower than Darnell's height is 71.57%

HELPP!!!! 100 points. Which expression is equivalent
devlian [24]

Answer:

\Large \boxed{\sf A}

Step-by-step explanation:

\displaystyle 2x\sqrt{44x}-2\sqrt{11x^3}

Let<em> x</em>  = 2 because x > 0

\displaystyle 2(2)\sqrt{44(2)}-2\sqrt{11(2)^3}=4\sqrt{22}

See which expression is equal to 4√22 when <em>x</em> = 2

2(2)\sqrt{11(2)}=4\sqrt{22}

The expression is option A
