2. 5,2,-1

3. 150,325,500,675

4. -9,-5,-1,3

Step-by-step explanation:

2. 5,2 5-2=3 or 2+3=5

3. 150,325,500 325+175=500 or 500-325=175

4. -9,-5,-1 -9+4=-5 or -9 - -5= 4

What is 1/4(x+16)-x equal too

schepotkina [342]

<span>1/4(x + 16) - x =

First, distribute the 1/4.

= 1/4x + 1/4 * 16 - x

= 1/4x + 4 - x

= 1/4x + 4 - 4/4x

= 1/4x - 4/4x + 4

= -3/4x + 4

$= -\dfrac{3}{4}x + 4$ </span>

Suppose that IQ scores have a bell-shaped distribution with a mean of 103 and a standard deviation of 15. Using the empirical ru

Lady_Fox [76]

Answer:

Probability = 0.15%

Step-by-step explanation:

The provided information is:

Let X be the scores of the IQ scores that is normally distributed with mean $\mu = 103$ and standard deviation

That is $X \sim N(103,15)$

$103 - 58 = 45 = 3 \times 15$

So, 58 is 3 standard deviation left to the mean.

As 99.7% of probability lies within the three standard deviation.

Thus, above three standard deviation is:

$\frac{1-0.997}{2}=0.0015$

Thus, the required probability is 0.15%

PLZ HELP ME QUICKLY! Replace the power with a product and then transform the product into a polynomial. (3a-1)^2

aniked [119]

Answer:

Product: $(3a-1)(3a-1)$

Polynomial: $9a^{2} -6a+1$

Step-by-step explanation:

$(3a-1)^{2}$ is equal to $(3a-1)(3a-1)$ . Then, expand it using the distributive property to get $9a^{2} -3a-3a+1$ which, simplified is $9a^{2} -6a+1$ .

Hope this helps :)
