Answer: The required transformation is the REFLECTION ACROSS Y-AXIS.

Step-by-step explanation: We are given to state the type of transformation described a follows :

$(a,b)~~~\Rightarrow ~~~(-a,b).$

We note the given transformation that the sign before the x co-ordinate changes.

This transformation gives the reflection of the point across y axis.

For example, if (a, b) = (1, 2), then after reflection across y axis, the point become

$(1,2)~~~\Rightarrow ~~~(-1,2).$

These two points are plotted on the co-ordinate plane as shown in the attached figure below.

Thus, the required transformation is the REFLECTION ACROSS Y-AXIS.

Find the mean, variance, and standard deviation of the binomial distribution with the given values of n and p. , The mean, ,

klemol [59]

Complete Question

Find the mean, variance, and standard deviation of the binomial distribution with the given values of n and p. , The mean, , is nothing. (Round to the nearest tenth as needed.)

p = 0.6 n = 18

Answer:

The mean $\mu = 10.5$

The standard deviation $\sigma = 2.08$

The variance $var = 4.32$

Step-by-step explanation:

From the question we are told that

The probability of success is $p = 0.6$

The sample size is $n = 18$

Generally given that the distribution is binomial, then the probability of failure is mathematically represented as

$q = 1- p$

substituting values

$q = 1- 0.6$

$q =0.4$

Generally the mean is mathematically evaluated as

$\mu = np$

substituting values

$\mu = 18 * 0.6$

$\mu = 10.5$

The standard deviation is evaluated as

$\sigma = \sqrt{npq}$

substituting values

$\sigma = \sqrt{18 * 0.6 * 0.4}$

$\sigma = 2.08$

The variance is evaluated as

$var = \sigma^2$

substituting value

$var = 2.08^2$

$var = 4.32$

Write y=-3/4 x-2 in standard form using integers.

jeyben [28]

Standard form is Ax + By = C

y = (-3/4)x - 2

Multiply both sides by 4.

4y = -3x - 8

Add 3x on both sides

3x + 4y = -8

Your final answer is 3x + 4y = -8.

Please help! I will mark as brainliest IF answer is right. <3

trasher [3.6K]

Solution

write the division as a fraction = 12y^4-4y^3 - 6y^2 + 36y - 22 over y-3 multiplied by r over y-3

r ×(2y^4 - 4y^3- 16y^2 + 36y- 22) over (y-3)^2

2ry^4 - 4ry^3 - 16ry^2 + 36ry - 22r over (y-3)^2
