Step-by-step explanation:
Move it it up 4 and then find your x intercepts.
Find the x intercepts.

<u>Move the 4 over to the right</u>

<u>Divide out the - </u>


<u>Take the square root of each side</u>


Our x intercepts are at (-2,0) (2,0)
5.20 time 8/100 the answer is0.42 and 0.42plus 5.20
The coin was heads 275 times out of 625 times, therefore, the other 350 times the coin was tails. the fraction is 350/625 which we can simplify to 14/25, which translates to a probability of 56%
Answer:
c = 21
Step-by-step explanation:
<u>**I assume that side WX in my diagram (attached as an image below) is the value of C that we're looking for. ALSO, the sizes and lengths of the parallelograms are NOT to scale.**</u>
If two parallelograms are similar, that means the lengths of the corresponding sides have EQUAL ratios.
PL corresponds with WZ. To get from 15 to 45, you would multiply 15 by 3, so the ratio of the legnths of the corresponding sides between these two parallelograms is 1:3.
With that in mind, we can apply this ratio to find WX.
We know that AP has a length of 7, so we will multiply that by 3, getting a value of 21, and 7:21 ratio is the same as 1:3.
c = 21
