Find x and y<br><br> helppppp !!
Anni [7]

3x + 6 = 48 (alternate angles are equal)

- 6

3x. = 42

÷3

x = 14 degrees

180-48 - 2y + 5y-9 =180

123 + 3y = 180

-123

3y = 57

÷3

y = 19 degrees

Explanation:

To find the last angle on the top straight line, do:

180 - (the 2 given angles).

So, 180 - (3x + 16, which is 48 due to alternate angles being equal). Then, minus the 2y.

(180 - 48 - 2y) & simplify => 132 - 2y

This gives you the equation for the missing angle on our top straight line.

Thus, co-interior angles add to 180. So, we add the new equation (132 - 2y) to 5y - 9.

Simplify

=> 123 + 3y (because - 2+5 =3)

and put it equal to 180. Solve for y

Hope this helps!

Answer:

Mean = £1.8 million


Step-by-step explanation:

The MEAN is the sum of all the numbers divided by the number of numbers.

  • <u>There are 5 numbers in total</u>
  • <u>The sum is 1.4+1.6+1.8+2.5+1.7=9 million</u>

Hence the mean is \frac{9}{5}=1.8 million

The mean percentage of a population of people eating out at least once a week is 57% with a standard deviation of 3.50%. Assume
Fed [463]
Since 68% of the sample ranges from the plus minus first standard deviation from the mean, then interval wherein it will occur will be between 53.5% to 60.5%. I got this answer through adding and subtracting one standard deviation (3.5) from the mean (which is 57).

1. Given f(x) =1/4 (x – 8), what is the value of f(24)?
goldenfox [79]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

f(24)=4

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

f(x)=\frac{1}{4}(x-8)\\-----------\\\rightarrow f(24)= \frac{1}{4}(24-8)\\\\\rightarrow f(24) = \frac{1}{4}( 16)\\\\\rightarrow\boxed{f(24)=4}

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.
