The formula for slope is: m = (y2 - y1) / (x2 - x1) ---> m = (b - b) / (-a - a) = 0/(-2a) = 0

Are 16% of M&M’s Green? Mars, Inc. claims that 16% of its M&M plain candies are green. A sample of 100 M&Ms is rando

wolverine [178]

Answer: This result is not unusual.

So, it does not seem that the claimed rate of 16% is wrong

Step-by-step explanation:

Since we have given that

n = 100

p = 0.16

q = 1 - 0.16 = 0.84

So, Mean would be

$np=100\times 0.16=16$

and standard deviation would be

$\sqrt{np(1-p)}=\sqrt{100\times 0.16\times 0.84}=3.67$

Now, if there are 19 green,

so, we will check how it is far,

$\dfrac{19-16}{3.67}=\dfrac{3}{3.67}=0.817$

Since it is 0.817 standard deviations away from the mean.

So, this result is not unusual.

So, it does not seem that the claimed rate of 16% is wrong.

What is the quadratic function f(x)=x^2+2x-2 in vertex form?

NemiM [27]

Given: f(x) = x² + 2x - 2
Add 2 to both sides: f(x) + 2 = x² + 2x
Complete the square: f(x) + 2 + (1) = x² + 2x + (1) → f(x) + 3 = (x + 1)²
Subtract 3 from both sides: f(x) = (x + 1)² - 3
