Eva earned the following test scores in science: 82, 100, 96, 90, 91 Ms. Wade entered the next score as 0 because Eva was absent

on test day and hadn’t had a chance to make up the test. Which statements are true based on the data? Check all that apply. After adding the 0 test score, the mean would be the most appropriate measure of center to describe the data. After adding the 0 test score, the mean would be affected. After adding the 0 test score, the median would be the most appropriate measure of center to describe the data. Before the missed test, Eva’s median score was 96. Before the missed test, Eva’s median score was 91. Before the missed test, Eva’s mean score was 91.8.

we know that

1) Before the missed test

a) mean=[82+100+96+90+91]/5=459/5------> 91.8

b) median

82,90,91,96,100-------> the median is 91


2) After adding the 0 test score

a) mean=[82+100+96+90+91+0]/5=459/6------> 76.5

b) median

0,82,90,91,96,100-------> the median is [90+91]/2-----> 90.5


therefore

a) After adding the 0 test score, the mean would be the most appropriate measure of center to describe the data-------> is true


b) After adding the 0 test score, the mean would be affected-----> is true


c) After adding the 0 test score, the median would be the most appropriate measure of center to describe the data-----> is false


d) Before the missed test, Eva’s median score was 96-----> is false


e) Before the missed test, Eva’s median score was 91------ is true


f) Before the missed test, Eva’s mean score was 91.8-----> is true

Three years ago, Sherman was twice as old as Clive. If Clive’s present age is c, which expression represents Sherman’s present a
OLEGan [10]
First establish variables for current age.

Clive's current age = c
Sherman's current age = s

<span>"Three years ago," 
Clive was: (c - 3)
Sherman was: (s - 3)

</span><span>"Sherman was twice as old as Clive."</span><span>
(s - 3) = 2(c - 3)

Then in terms of Sherman's present age, distribute 2, combine like terms
s - 3 = 2c - 6
s = 2c - 6 + 3
s = 2c - 3

Suppose students' ages follow a skewed right distribution with a mean of 24 years old and a standard deviation of 3 years. If we
natta225 [31]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Mean of students' age = 24 years

Standard deviation of students' age = 3 years

Sample size = number of students = 350

So, according to options,

a. The shape of the sampling distribution is approximately normal.

It is true as n >30, we will use normal.

b. The mean of the sampling distribution is approximately 24-years old.

It is true as it is given.

c. The standard deviation of the sampling distribution is equal to 5 years.

It is not true as it is given 3 years.

Hence, Option 'c' is correct.

) If the pattern shown continues, how many black keys appear on a portable keyboard with 49 white keys? Suggestion: use equivale
andriy [413]

Answer:

35

Step-by-step explanation:

Here we see 5 black keys for every 7 white keys.

So the ratio is 5:7

If we need 49 white keys, find the amount we scale the original ratio by:

    49/7 = 7

So we are scaling by a factor of 7.

The number of black keys would be 5 * the scale of 7. = 35

So there should be 35 black keys.
