Answer:11/14
Step-by-step explanation:
Let's multiply the numerators first. 22 x 1 is 22, so your numerator is 22.
The denominator: 7 x 4= 28, your denominator is 28.
Your answer <u><em>would</em></u> be 22/28.
However, we can simplify this.
22 and 28 are both divisible by 2.
22/2=11
28/2=14
Your final answer is <u><em>11/14</em></u>
Answer:
To transform from polar coordinates into Cartesian coordinates we have:
x = r x cos(theta)
y = r x sin(theta)
r^2 = x^2 + y^2
=> r = 2*cos(theta)
<=> r = 2*(x/r)
<=> 2x = r^2
<=> 2x = x^2 + y^2
Hope this helps!

Answer:
H_0: p_1 =p_2\\H_a: p_1<p_2
Step-by-step explanation:
Given that in the past, 25% of the town residents participated in the school board elections.

Okay well ill do the first on and explain it so hopefully you can do the rest
3 and 1/3 is equal to 10/3 because a whole number would be 3/3 and we have 3 whole numbers plus 1/3
3/3
3/3
3/3
