Answer:

$\frac{-47}{6}$ = $7.833$

Step-by-step explanation:

Expression given is:

$-4\frac{2}{3} -(3\frac{1}{6})$

Now change the mixed fraction to improper fractions;

$-\frac{14}{3} -\frac{19}{6}$

Now take a common denominator:

$-\frac{28}{6} -\frac{19}{6}$

Now we can simplify the the above equation:

$\frac{-28-19}{6}$

$\frac{-47}{6}$ = $7.833$

20000 students took a standardized math test. The scores on the test are normally distributed, with a mean score of 85 and a sta

Tpy6a [65]

Answer: 2718

Step-by-step explanation:

Given: Mean score = 85

Standard deviation = 5

Let x be the score of a random student that follows normal distribution.

Then, the probability that a student scored between 90 and 95 will be

$P(90< x < 95)\\\\=P(\dfrac{90-85}{5}$

The number of students scored between 90 and 95 = 0.1359 x (Total students)

= 0.1359 (20000)

= 2718

Hence, The number of students scored between 90 and 95 = 2718

Find the value of x in the given figure using properties of parallel lines.

marshall27 [118]

Answer:

x =42

Step-by-step explanation:

x and 138 are same side interior angles. Same side interior angles are supplementary when the lines are parallel

x+138 = 180

x = 180-138

x =42

Which of the following describes the transformation of g (x) = 3 (2) Superscript negative x Baseline + 2 from the parent functio

Tanzania [10]

Option d: reflect across the y-axis, stretch the graph vertically by a factor of 3, shift 2 units up.

Step-by-step explanation:

The parent function is $f(x)=2^{x}$

The transformation function is $g(x)=3(2)^{-x} +2$

In the transformed function, the function is added +2, which shifts the graph by 2 units up.

Also, the function is multiplied by 3, which stretches the function $f(x)=2^{x}$ vertically by a factor of 3 units.

The variable x is multiplied by -1, such that the function reflects across y-axis.

Thus, the correct answer is option d.

The graph is attached below which shows the parent function and the transformed function.

The transformation function is reflect across the y-axis, stretch the graph vertically by a factor of 3, shift 2 units up.
