Answer:

  • Option C
  • Option B

Step-by-step explanation:

<u>Let's simplify this further to get our answer.</u>

  • -5/6(12 - 6x + 18y)
  • => -60/6 + 30x/6 - 90y/6
  • => -10 + 5x - 15y

Looking at the options, we can say that Option C and B are correct.

\\ \sf\longmapsto \dfrac{-5}{6}(12-6x+18y)

\\ \sf\longmapsto \dfrac{-5}{6}(12)-\dfrac{(-5)}{6}(6x)+\dfrac{-5}{6}(18y)

\\ \sf\longmapsto -5(2)-(-5x)+(-5)(3y)

\\ \sf\longmapsto -10+5x-15y

The length of a human pregnancy is normally distributed with a mean of 270 days with a standard deviation of 8 days. How many da
solniwko [45]

Answer:

261.71

Step-by-step explanation:

The calculation of days is shown below:-

X = \mu + Z\sigma

where,

Mean = 270

standard deviation is 8

And, the normsinv is -1.036

Now placing these values to the above formula

So, the number of days is

= 270 + (-1.036433389)  × 8

= 270 + (-8.29146711)

= 261.708533

or

= 261.71

Therefore for computing the number of days we simply applied the above formula and for (-1.036433389) please find in the attachment.

Given a quadratic function in vertex form:
Alja [10]

Answer:

See below

Step-by-step explanation:

<u>Part A</u>

A vertical stretch takes place when a\cdot f(x) given that  |a| > 1

<u>Part B</u>

A vertical compression takes place when a\cdot f(x) given that 0 < |a| < 1

<u>Part C</u>

A vertical stretch is different than a horizontal compression:

  • In a vertical stretch, the input stays the same, but the output is multiplied by the scale factor
  • In a horizontal compression, the output stays the same, but the input is multiplied by the scale factor

<u>Part D</u>

A reflection across the x-axis means that the output, our y-variable, is the opposite sign. This means that all values of a must be negative such that a\cdot f(x) as mentioned in parts A and B. Also, in part C, since our scale factor is negative, the output is the only one being multiplied by the scale factor.

How to solve:<br> 8(2)-4<br>________<br>8÷4 ?
MissTica
So the first thing you do is dove the equations. Let's do the numerator equation. 8(2)-4 is simply saying 8•2-4 and i don't know if u learned this in class yet but you do multiplication and division before addition and subtraction so 8•2=16-4=12 so now 12 is our numerator. Now for the denominator, 8/4=2 so 2 is our denominator. We have 12/2 but it can be simplified to 6 because 6 goes into 12 twice and u cans check this by doing 6•2=12
Hope this helps m8 :))
