Many companies "grade on a bell curve" to compare the performance of their managers and professional workers. This forces the us

GarryVolchara [31]

Answer:

option A

Step-by-step explanation:

given,

10% A grades 80% B grades 10% C grades

This year, managers with scores less than 35 received C's and those with scores above 425 received A's.

The mean has to be middle of two corresponding cutoff value

$\mu = \dfrac{35+425}{2}$

μ = 230

Cutoff Off C grade corresponds with the area of 0.10 is table A.

corresponding z- score according to Table A

Z = -1.28

now, standard deviation

$z = \dfrac{x-\mu}{\sigma}$

$\sigma= \dfrac{x-\mu}{z}$

$\sigma= \dfrac{35-230}{-1.28}$

σ = 152.3

Correct answer is option A

The ratio of orange juice to pinapple jucie in tropical treat punch is 4 to 3. Bill has 64oz of orange juice. How many pineapple

iogann1982 [59]

We are given :

The ratio of orange juice to pineapple juice in tropical treat punch = 4:3 or 4/3.

Number of oz of orange juice = 64 oz.

Let us assume number of oz pineapple juice does he need = p.

We can setup an proportion:

64 : p = 4 : 3

$\frac{64}{p} = \frac{4}{3}$

On cross multiplication we get

64 × 3 = 4 × p

192 = 4p

Dividing both sides by 4, we get

p = 48.

<h3>Therefore, he needs 48 oz of pineapple juice.</h3>

1.) What is the mode of the data ? Show work ( A.3, B.5, C.8, D.10 )

ArbitrLikvidat [17]

Hey there.

1.) The mode is the number that's most frequent in a given list.
In our list, we have 2, 4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 9, 10.
Our most frequent number is 6; therefore, our mode is 6.

2.) The median is the number in the middle of a list organized from least to greatest.
2, 4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 9, 10;
4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 9;
4, 5, 5, 5, 6, 6, 6, 6, 7;
5, 5, 5, 6, 6, 6, 6;
5, 5, 6, 6, 6;
5, 6, 6;
6.
6 is our median.

I hope this helps, despite your answer choices not providing the correct answer.

What fraction would you add to 29/6 to make 4

Zigmanuir [339]

Keeping in mind that 29/6 is greater than 4, is actually 4 and 5/6, so the amount we'll "add" will be a negative one.

$\bf \cfrac{29}{6}+x=4\implies x=4-\cfrac{29}{6}\implies x=\cfrac{4}{1}-\cfrac{29}{6}\implies x=\cfrac{(6)4-(1)29}{6}
\\\\\\
x=\cfrac{24-29}{6}\implies x=\cfrac{-5}{6}\\\\
-------------------------------\\\\
\cfrac{29}{6}+\left( -\cfrac{5}{6} \right)=4$
