Anna007 [38]

Answer:

<u>Given data:</u>

  • 4, 5, 3, 3, 1, 2, 3, 2, 4, 8, 2, 4, 4, 5, 2, 3, 6,2

<u>Put the data in the ascending order:</u>

  • 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 4, 5, 5, 6, 8

<u>Mean, the average:</u>

  • (1 + 2*5 + 3*4 + 4*4 + 5*2 + 6 + 8)/18 = 3.5

<u>Median, average of middle two numbers:</u>

  • 3

<u>Mode, the most repeated number:</u>

  • 2 (repeated 5 times)

Mean is normally the best measure of central tendency, same applies to this data.

A catering company’s recipe for salad uses a ratio of 2 c of dressing to 4 lb of vegetables. Draw a model for the ratio. Write t
s2008m [1.1K]
The ratio of dressing to vegetable in its reduced form is determined by dividing the amount of dressing by the amount of vegetables. This will give us the answer of,
                                       2 c / 4 lb
In its simplest form, we divide both the numerator and denominator by 2 and the final answer would be,
                                              1 c / 2 lb

What is the area of a cross section that is parallel to face CDHG ?
Dennis_Churaev [7]

Answer: Area of cross section that is parallel to face CDHG is 432 cm².

Step-by-step explanation:

Since we have given that

There is a cross section that is parallel to face CDHG.

So, Length of cross section would be 36 cm

Width of cross section would be 12 cm.

So, Area of cross section would be

Length\times breadth\\\\=36\times 12\\\\=432\ cm^2

Hence, Area of cross section that is parallel to face CDHG is 432 cm².

Assume that women's heights are normally distributed with a mean given by , and a standard deviation given by . μ = 63.5 in σ =
tresset_1 [31]
<span> (a) if 1 woman is randomly selected, find the probability that her height is less than 64 in
using z-score formula:
z-score=(x-mu)/sig
(64-63.5)/2.8
=0.18
thus
P(x<64)=P(z<0.18)-=0.5714

B] </span><span> if 33 women are randomly selected, find the probability that they have a mean height less than 64 in
using the central limit theorem of sample means, we shall have:
2.8/</span>√33=0.49
since n>30 we use z-distribtuion
z(64)=(64-63.5)/0.49=1.191
The
P(x_bar<64)=P(x<1.191)=0.8830
