Answer:
Find the relative frequency for the event "heads" for each friend:
Friend 1: 0.59 (41/70)
Friend 2: 0.7 (49/70)
Friend 3: 0.37 (26/70)
If the friends combine their results to get 116 heads and 94 tails, what is the relative frequency for the event "heads"?
0.55 (116/210)
Suppose each friend flips a coin 700 times. Is there a value you would expect the relative frequency for the event "heads" to be close to?
For Friend 1, basing it off the 0.59 frequency from earlier, I would expect the heads to be around 413.
Friend 2, 490
Friend 3, 259
Answer:
x=9, y=-4. (9, -4).
Step-by-step explanation:
2x+5y=-2
4x+7y=8
--------------
-2(2x+5y)=-2(-2)
4x+7y=8
---------------------
-4x-10y=4
4x+7y=8
--------------
-3y=12
y=12/-3
y=-4
2x+5(-4)=-2
2x-20=-2
2x=-2+20
2x=18
x=18/2
x=9
<u>Answer:</u>
$9.65
<u>Step-by-step explanation:</u>
We are given that Jada deposited $867 into a savings account that pays a simple annual interest rate of 0.89% and we are to find the interest she will earn after 15 months.
So we will use the formula:
Interest = P × R × T
where P = principal, R = rate, T = time in years
Substituting the given values in the above formula:
Interest = 
× 
× 
= $9.65
Answer:
<h3>
Step-by-step explanation:</h3>
<u>Cross multiply:</u>
(Multiply the numerator in the first fraction times the denominator in the second fraction, then multiply the numerator of the second fraction times the number in the denominator of your first fraction.)
<u>Switch sides:</u>
<u>Divide both sides by 19:</u>
<u>Divide 798 by 19 = 42</u>

Answer:
(-6,6), (0,12), (4,8)
Step-by-step explanation:
To dilate an object, we need to multiply the x and y values by the given scale factor.
In this case the scale factor is 2 --> 2(x, y)
Before-> After dilation
2(-3,3) = (-6,6)
2(0,6) = (0,12)
2(2,4) = (4,8)
