Answer:
c) alternate hypothesis
Step-by-step explanation:
Answer:
as a fraction = 75/92
as a percentage = 81.52%
Step-by-step explanation:
total no of students = 92
probability that a student has hazel or brown eyes = Pr(hazel or brown)
but probability of a or b happening ie Pr(a or b) simply is Pr (a) +Pr (b)
therefore Pr(hazel or brown) = Pr(hazel)+ Pr(brown)
Pr(brown) = (no of brown eyes )/(total set of eyes)
=
= 10/23
Pr( hazel) = (no of hazel eyes )/(total set of eyes)
=
=35/92
hence Pr(hazel or brown) = (10/23) + (35/92) =75/92
so there's 75/92 probability (or 0.8 out of 1 chance )to choose either hazel or brown randomly
Answer:
C. ![y=\sqrt[3]{-x} -1](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B-x%7D%20-1)
Step-by-step explanation:
Consider the eparent function
The graph of this function is shown in the attached diagram - red curve.
Reflect this graph across the y-axis, you'll get the blue line which equation is
![y=\sqrt[3]{-x}](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B-x%7D)
Translate this graph 1 unit down, then you'll get green line (that is exactly the graph from your image) and the function for this line is
![y=\sqrt[3]{-x} -1](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B-x%7D%20-1)
Answer:
13.3
Step-by-step explanation:
ad 28, 13, 4, 8, 15, 10, 22, 7, 11, 15 all together which equals 133
The 133 divided by 10 = 13.3
Answer:
There is a typo near the equal sign.
There can be two different answers if we think that = sign as + or -.
First way: Making = as +
=> 10 - [14 + (3+4) x 2] +3
=> 10 - [14 + 7 x 2] + 3
=> 10 - [14 + 14] + 3
=> 10 - 28 + 3
=> 10 + 3 - 28
=> 13 - 28
=> -15
=> So, -15 is the answer if we consider "=" sign as "+" sign.
Second way: Making = as -
=> 10 - [14 - (3+4) x 2] + 3
=> 10 - [14 - 7 x 2] + 3
=> 10 - [14 - 14] + 3
=> 10 - 0 + 3
=> 10 + 3
=> 13
=> So, 13 is the answer if we consider "=" sign as "-" sign.
