The area of a rectangular ice rink is 900 sq. yards. If the length of the rink is 100 yards what is the width of the rink?

1 answer:

3 0

Easy! Multiply 100 by 2 and get 200. Then subtract 900 by 2, and get 700. Then you divide 700 by 2 (because there are only 2 sides left!) and BAMMMMMM there’s your answer

Suppose a polling agency reported that 45.7% of registered voters were in favor of raising income taxes to pay down the national

sineoko [7]

<h2>Answer with explanation:</h2>

As per given , we have

p= 0.457

n= 1033

Margin of error for 99% confidence : E= 4%=0.04

Confidence interval : $p\pm E$

i.e. $0.457\pm 0.04$

$=( 0.457- 0.04,\ 0.457+0.04)=(0.417,\ 0.497)$

99% confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt. = (0.417, 0.497)

Interpretation : We are 99% sure that the true population proportion of registered voters who are in favor of raising income taxes to pay down the national debt lies in interval (0.417, 0.497).

Answer:

See below

Step-by-step explanation:

Given :-

y || z

To Prove :-

m∠5 + m∠2 + m∠6 = 180°

Proof :-

Here we are required to prove that ,

$\rm\implies m\angle 5 + m\angle 6 + m\angle 2 = 180^o$

And here it's given that , y || z . Therefore ,

∠3 = ∠6 ( alternate interior angles )
∠1 = ∠5 ( alternate interior angles )

Now we know that the measure of a straight line is 180°. Therefore ,

$\rm\implies m\angle 1 + m\angle 2 + m\angle 3 = 180^o \\\\\implies\boxed{\rm m\angle 5 + m\angle 6 + m\angle 2 = 180^o}$

From 1 and 2 .

Hence Proved !
