Answer:

(x+3, y+2)

Step-by-step explanation:

choose a letter: let's use points A and A'

A: (-3, 3)

A': (0, 5)

the rule would be (x+3, y+2) because (-3+3, 3+2) = (0,5)

Try it on another point:

B: (-4, 0)

B': (-4+3, 0+2) = (-1, 2) which checks out!

Misha Larkins [42]

$f(x)=x^2+2x-4\\
f'(x)=2x+2\\\\
2x+2=0\\
2x=-2\
x=-1\\\\
f(-1)=(-1)^2+2\cdot(-1)-4=1-2-4=-5\\
f(1)=1^2+2\cdot1-4=1+2-4=-1\\\\
f_{min}=-5\\

suppose the normal distribution has a mean of 98 and a standard deviation of 6. what is P(x < 92)? 0.16 0.025 0.84 0.975

tresset_1 [31]

Answer:

P(x < 92) is 0.16

Step-by-step explanation:

We are given that the normal distribution has a mean of 98 and a standard deviation of 6.

Mean = $\mu = 98$

Standard deviation = $\sigma = 6$

We are supposed to find P(x < 92)

Formula : $Z=\frac{x-\mu}{\sigma}$

$Z=\frac{92-98}{6}$

Z=-1

Refer the z table for p value

So,p value = 0.1587

So, P(x < 92) is 0.16

Option A is true

Hence P(x < 92) is 0.16
