One side = x
The other side = x+3.5
Perimeter is 2(L*w)
Perimeter is 2(x + x + 3.5)
2(2x + 3.5) = 67
4x + 7 = 67
4x = 60, x = 15
15 + 3.5 = 18.5
One side is 15cm, the other side is 18.5 cm

Days before a presidential election, a nationwide random sample of registered voters was taken. Based on this random sample, i

dimaraw [331]

Answer:

D. No, because 50% is within the bounds of the confidence interval.

Step-by-step explanation:

"52% of registered voters plan on voting for Robert Smith with a margin of error of plus or minus±3%"

This means that the 95% confidence interval for the percentage of people that plan on voting for Robert Smith is

(52-3 = 49%, 52+3 = 55%).

We can't say that he will win the election, because at the 95% confidence level, the proportion is not guaranteed to be above 50%.

So the correct answer is:

D. No, because 50% is within the bounds of the confidence interval.

eliot counts a group of coins staring with the quarters his sister counts the same coins she counting the pennies wiil they get

zalisa [80]

Answer: No, they would not get the same amount.

Step-by-step explanation:

Let the number of coins be x

Eliot counts a group of coins staring with the quarters.

As we know that

$1\ quarter=25\ cents$

So, Number of amount Eliot counts with the quarters is given by

$25\times x=25x\ cents$

Similarly, His sister counts the same coins she counting the pennies .

As we know that

$1\ penny=1\ cent$

So, Total amount his sister counts with the pennies is given by

$1\times x=x\ cents$

But we can see that

$25x\ cents\neq x\ cents$

Hence, No, they would not get the same amount.
