Answer:
3) 16π cm²
4) 240.625 cm²
Step-by-step explanation:
<em>3. For this problem I'm going to use the formula Area = π × r²</em>
<em>To start off, I'm going to input our value of radius which is 4cm.</em>
π × 4²
<em>Finally, I'm going to square our value "4"</em>
16π cm²
<em>(I'm going to "leave my answer in terms of π" as the problem states but if you need the complete answer it would be </em>about 50.24 cm²
<em>4. For this problem I'm going to use the formula Area = π × (d/2)²</em>
<em>To begin, I will divide our diameter by 2 to find the radius.</em>
17.5/2 = 8.75
<em>Next, we are going to square our now, radius.</em>
8.75² = 76.5625
<em>Now, we have to multiply our squared radius by π (in this problem it states to use 22/7, so that's what we'll do :)</em>
76.5625 × 22/7 = 240.625 cm²
<em>So! This is our final answer!</em>

Its easier to find the complement of that instead
so you find the probability of 1 and 0
The .2 in the answer is the probability of each question 1/5
(10 C 0) x .2^0 (1-.2)^10-0=.1074
(10 C 1) x .2^1 (1-.2)^10-1=.2684
.2684+.1074=.3758 and that's the complement
so 1 - .3758= .6242
I too have a stats exam on this tomorrow lol

Answer:
(0,0) and (7,10)
Step-by-step explanation:
recall that the slope - intercept form of a linear equation can be given as
y = mx + b
where m = slope and b = y intercept
in our case, we are given that slope, m = 10/7, hence our equation becomes
y = (10/7) x + b
since we are not given any information about the y-intercept, we can simply pick a value for b that is most convenient for us.
We pick b = 0, hence the equation simplifies to:
y = (10/7) x ----- eq 1
we can see immediately that if x = 0, y must also = 0
proof if x = 0:
y = (10/7)(0) =0
since 0 is an integer, then (0,0) must be the first point.
we can also observe that for y to be an integer, we must get rid of the denominator 7. We can do this by multiply the right side by 7. Hence we let x = 7:
y = (10/7) x 7
y = 10
hence (7,10) is the second point.
