Answer:

Constitution will not be amended.

Step-by-step explanation:

To amend the country's constitution, number of states should approve the amendment = \frac{7}{9} of 69

= \frac{7}{9}\times 69

= 53.67

≈ 53 states

But the states who approved the amendment = 52

And 52 < 53

Therefore, constitution will not be amended.

Blizzard [7]

Answer:

2.275%

Step-by-step explanation:

We start by calculating the z-score

Mathematically;

z-score = (x-mean)SD

here, x = 70.5

mean = 65.5

SD = 2.5

Substituting these values;

z = (70.5-65.5)/2.5

= 5/2.5 = 2

So we want to calculate the probability that;

P( z> 2)

We check the standard normal distribution table for this

That will be

0.02275

In percentage, this is 2.275 %

Hi! I'm Jenny and I'm a mathematician! I'd love to help you with this problem! :)

Lets get started...

I'll write the equation out for you!

x + x(xx)

Put the value of x = 2 in the above expression we get,

2 + 2(22)

= 2 + 2(2 × 2)

= 2 + 2(4)

= 2 + 8

= 10
