Answer:

c = -4.5
z = 20
x = -12
a = -4/7

Step-by-step explanation:

A way to do this that will always work is ...

eliminate parenthses and collect terms
subtract any constants from the left side
subtract any variable terms from the right side
divide by the coefficient of the variable

8c -11 -6c = -2
2c -11 = -2
2c = 9
c = 4.5

3z +4 -2z -9 = 15
z -5 = 15
z = 20

12 -4x +18 = 36 +4x +18 -6x
30 -4x = 54 -2x
-4x = 24 -2x
-2x = 24
x = -12

36a -9a -5 = 6a -17
27a -5 = 6a -17
27a = 6a -12
21a = -12
a = -12/21 = -4/7

Candice is preparing for her final exam in Statistics. She knows she needs an 74 out of 100 to earn an A overall in the course.

Answer:

Hence the correct option is option b) Yes, the upper level of one standard deviation is 72.

A score of 74 is not within one standard deviation of the mean.

Step-by-step explanation:

Here the given details are,

Mean = 68

SD = 4

Distribution is normal.

Z-score for x = 74 is given as below:

$Z = (X - mean)/SD\\Z = (74 - 68)/4\\Z = 1.5$

So, the score of 74 is 1.5 standard deviations from the mean.

$Mean + 1\timesSD = 68 + 1\times4 = 72Mean - 1\timesSD = 68 - 1\times4 = 64$

Therefore the score is not lies between 64 and 72.

Yes, the upper level of one standard deviation is 72.

H(x) = x + 1 k(x) = x - 2 (h + k)(2) =

barxatty [35]

$h(x) = x + 1$

$k(x) = x - 2$

_________________________________

$(h + k)(x) = h(x) + k(x)$

$(h + k)(x) = (x + 1) + (x - 2) \\$

$(h + k)(x) = x + 1 + x - 2$

$(h + k)(x) = 2x - 1$

$(h + k)(2) = 2(2) - 1$

$(h + k)(2) = 4 - 1$

$(h + k)(2) = 3$

Give me three disadvantages of rote learning

alexdok [17]

Using rote learning with more advanced subjects is generally that students can immediately forget the facts they have learned after the tests, and might not fully understand the concepts to begin with.
