Statisticians use ______ scores to divide the ______ under a curve the way people use a knife to cut pizza. Just as the pizza is
solong [7]

Answer:

Statisticians use z-scores to divide the area under a curve the way people use a knife to cut pizza.

Step-by-step explanation:

Statisticians use z-scores to divide the area under a curve the way people use a knife to cut pizza.

z-score:

  • A z-score is a numerical measurement which is measured in terms of standard deviations from the mean.
  • Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

  • If a z-score is 0, it tells that the data point is same as the mean.
  • Area under the normal curve is 1.

F(x)=1/x and g(x)=x-4<br> Can you evaulate (g o f)(0) explai sn why or why not
Ostrovityanka [42]

Hello from MrBillDoesMath!

Answer:

 (g o f)(0) cannot be evaluated

Discussion:

(g o f)(0) = g ( f(0))  if it exists but f(0) is not defined (as division by zero is not defined) so   (g o f)(0) cannot be evaluated

Thank you,

MrB

Evelyn and Meredith decided to kayak 1 mile up and then back in the Humboldt channel.
Yakvenalex [24]

The rate of the water flowing in the channel was 2 miles per hour, the rate Evelyn and Meredith were paddling is mathematically given as

v+ = 2.29 1mile/hour

<h3>What is the rate Evelyn and Meredith were paddling?</h3>

Generally, the equation for the up and downstream motion is mathematically given as

vup=v-2

vdown=v+2

Therefore, Statement interpretation

2/3=40*1/60

3+2/3hr=11/3

Where, tup+tdown=11/3

tup+tdown=11/3

1/Vup+1/vdown=11/3

Considering the LCD equation

3(v-2)(V+2)

Hence

\frac{3(v-2)(v+2)}{v-2}+\frac{3(v-2)(v+2)}{v+2}=\frac{11(3)(v-2)(v+2)}{3}\\\\3(v+2)+3(v-2)=11(v+2)(v-2)

11v^2-6v-44=0

v=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

Resolving using the equation we have

v+ = 2.29 1mile/hour

v- = -1.745 mile hour
