Answer:
The answer is attached!
Step-by-step explanation:
But, to find the relative frequencies you will have to find the total number of responses, which is 143.
Then you will go to each box and divide the number given by the total number of response. I will show you each box below:
[tex]\frac{62}{143} = .43\\\\\frac{32}{143} = .22\\\\\frac{29}{143} = .20\\\\\frac{20}{143} = .14[/tex]
(Note here that all these add up to exactly 1 when you don't round them, but I rounded them and they add up to .99)
Hope this helps!!

Question: (help please?!?!)Bridget has $2,835 in her savings account. Each pay period, $945 is deposited into
her savings account. If her paycheck deposits are the only transactions, which of the
following equations could be used to find y, the amount in her savings account based
on x, the number of times she is paid?
A y = 2,835 - 945x
B 2,835y = 945x
C y = 945x + 2,835
D y = 2,835x + 945
Answers
Answer:
C. y = 945x + 2,835
Step-by-step explanation:
Each pay period 945 dollars is deposited so that's the slope, which x stands for each pay period. She already started with 2,835 in her savings account so that is the y-intercept.
Slope: 945x
Y- intercept: 2,835
Therefore,
equation: y = 945x + 2,835

Step-by-step explanation:

add ( half the coefficient of the x- term )² to x² + 7x
x² + 2([tex]\frac{7}{2}[/tex] )x + [tex]\frac{49}{4}[/tex] , thus

Using the elimination method, we can solve this system of equations. You must find a common multiple of both equation for either x or y. I chose to multiply equation 2 by (-2) so that the x would be eliminated, allowing us to solve for y.

after eating at a restaurant the bill for your table is $62.50. There is a 6% sales tax and you want to leave a tip for 18% based on the pre-tax amount. How much money do you need to cover your final bill?
Answers
Answer:
Step-by-step explanation:
Your bill is $62.50
$62.50 * .06 = $3.75 (this is your sales tax added)
So your total is up to: $66.25
Adding the tip the same way using $66.25 *.18 = $11.93
Tip would be $11.93
Total coming to: $78.17
hope this helps
Answer:
$77.50
Step-by-step explanation:
Tax:
62.50x0.06= 3.75
3.75+62.50= 66.25
Tip:
62.50x0.18= 11.25
Answer:
66.25+11.25= 77.50
Find the value of "x".
Answers
Answer:
x = 4.52984
Step-by-step explanation:
Since the triangle has a right angle you need to use the the trigonometric function cos (theta which is the angle given that isn't 90°) = adjacent / hypotenuse (adjacent is the side close to the angle you're using which is 22° and the hypotenuse is the longest side of the triangle that is in the away from the right angle)
From there you plug in the numbers which now become cos (22°) = 4.2 / x
Then you isolate the x by multiplying it to both sides so it's on the left and divide both sides by cos (22°) which will end you up x = 4.2 / cos (22°)
Then you just divide and you 4.52984
