Answer:
Step-by-step explanation:
Let the angles which are in ratio be 5x and 7x respectively.
Now,
5x + 7x = 180
=> 12x = 180
=> x = 15
Hence the measure of both the angles are 75 degree and 105 degree.
Answer:




So then the % expected would be:

So then the answer would be 75%
Step-by-step explanation:
For this case we have the following info given:
represent the true mean
represent the true deviation
And for this case we want to find the minimum percentage of sold homes between $211,600 and $238,400.
From the chebysev theorem we know that we have
% of values within
if we use this formula and the limit given we have:




So then the % expected would be:

So then the answer would be 75%
Answer:
2x - 4
Step-by-step explanation:
We will have to use one variable.
Let's use "x" and call that number of shots taken by "Kyle"
So, we say:
Kyle takes "x" shots
It is told that Ben takes 4 fewer shots than Kyle, so:
Ben takes "x - 4"
So, the amount of shots both take is the sum of both shown above. So,
Total Shot = x + x - 4
Simplifying:
<u>2x - 4</u>
Because y is 8 and x is 3 you just have to add it in the equation which means to times it,(8)2-3(3)
8x2=16
3x3=9
16-9=7
