Determine whether the underlined value is a parameter or a statistic. The average score for a class of 28 students taking a calc

Veronika [31]

Answer:

Option D is right

Step-by-step explanation:

Given that the average core for a class of 28 students taking a calculus midterm exam was 72%

Parameters are numbers that summarize data for an entire population. Statistics are numbers that summarize data from a sample, i.e. some subset of the entire population.

From the above we see that the measurements pertaining to samples are statistics.

Thus 72 is a statistic

Pre image ABCD was dilated to be image A’B’C’D, where the center of dilation is the origin. What scale factor was used in the di

ArbitrLikvidat [17]

Answer:

The scale factor is 0.25

Step-by-step explanation:

we know that

The dilation is a non-rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

ABCD and A'B'C'D' are similar

therefore

$\frac{A'B'}{AB}=\frac{B'C'}{BC}=\frac{C'D'}{CD}=\frac{A'D'}{AD}$

Find the scale factor

Looking at the graph

we have

$A'B'=1\ unit\\AB=4\ units$

Let

z ---> the scale factor

$z=\frac{A'B'}{AB}$

substitute the values

$z=\frac{1'}{4}=0.25$

YOU HAVE 8 COINS IN A BAG. 3 OF THEM ARE UNFAIR AND THEY HAVE 60% CHANCE OF COMING UP WITH HEAD WHEN FLIPPED. YOU RANDOMLY CHOSE

madreJ [45]

Answer:

0.29125 or 29.125%

Step-by-step explanation:

For the five fair coins, the probability of coming up head when flipped is 0.5, so for two flips: 0.5*0.5 = 0.25, for each of these coins. So, the probability to take on of them is 5/8, and the probability of coming up with head: (5/8)*0.25 = 0.15625.

For the unfair coins, the probability of coming up with heads is 0.6, so for two flips: 0.6*0.6 = 0.36 for each unfair coins. The probability to chose one of them is 3/8, and the probability of coming up with head: (3/8)*0.36 = 0.135.

These probabilities are dependent, so to have the total probability we must sum them:

P = 0.15625 + 0.135

P = 0.29125 or

P = 0.29125 x 100% = 29.125%
