Answer:
C. Same is not an orange belt and Kate is not a red belt.
Step-by-step explanation:
A negation is an operation that "takes a statement and changes it to a statement whose true or false value is opposite". For example, if I were to say 2 + 2 = 4, the negation would be that 2 + 2 ≠ 4.
So, if Sam is an orange belt and Kate is a red belt, the negation is C. Same is not an orange belt and Kate is not a red belt.
Hope this helps!
Answer:
Null hypothesis: <em>μ₁</em> = <em>μ₂</em>.
Alternate hypothesis: <em>μ₁</em> > <em>μ₂</em>.
Step-by-step explanation:
The experimenter want to see whether laboratory rats would, on average, eat more when confined to a crowded cage or an uncrowded one.
(1)
The null hypothesis for this test is defined as:
<em>H</em>₀: The rats would, on average, not eat more when confined to a crowded cage or an uncrowded one, i.e. <em>μ₁</em> = <em>μ₂</em>.
(2)
The alternate hypothesis will be directional. This is because the experimenter wants to determine whether the rats eat more or not.
So the alternate hypothesis is:
<em>H</em>ₐ: The rats would, on average, eat more when confined to a crowded cage or an uncrowded one, i.e. <em>μ₁</em> > <em>μ₂</em>.
Answer:
50%
Step-by-step explanation:
60-40=20
20/40*100=50
58 because 80 times 15 percent is 12. so you subtract 12 from 80 that gives you 68 then you subtract the coupon which is 10 dollars. you total is 58.
Answer:
2. C. { 0, 1, 2}
3. B. 53
6. P = 14n + 10
Step-by-step explanation:
2. The domain is the input values (or the x values)
The domain is { 0,1,2}
3. f(x) = 5x+3
where x is the number of minutes. We will let x = 10
f(10 ) = 5*10 +3
= 50+3
= 53
53 cars will pass
6. When we have 1 trapezoid, the perimeter is 5+5+8+6 = 24
When we have 2 trapezoids, the perimeter is 5+8+6+5+8+6 = 38
We add 14, when we add a second trapezoid
P = 14n + 10
p(1) = 14+10 Check for 1 trapezoid
p(2) = 14*2 +10 = 28+10 = 38 check for 2 trapezoids
