Answer:
When number of bricks is multiplied by 2, the length is multiplied by
B) 2
Step-by-step explanation:
Number of bricks is two times the length of the wall
i.e. Number of bricks= 2×Length of the wall
When the number of bricks is multiplied by 2, the length is also multiplied by 2
since, when number of bricks=6 then, length of wall=3
and when number of bricks=2×6=12 then, length of wall=2×3=6
Hence, when number of bricks is multiplied by 2, the length is multiplied by
B) 2
Well I can't be for sure but I know for a fact its not set IV it's not possible to make a triangle out of all right angles. Set II, well, that isn't right either. You can't make a triangle out of all obtuse angles. Like the right angle one, its not possible you can only use one obtuse or right angle in a triangle other wise it's not going to be a triangle. I'd say go try Set III since that would most likely make an equilateral triangle.
Options:
A. Null hypothesis : u>30 Alternative hypothesis :u<30
B. Null hypothesis :u>30 Alternative hypothesis :u=30
C. Null hypothesis :u=30 Alternative hypothesis :u≠30
D. Null hypothesis:u=30 Alternative hypothesis :u>30
Answer:
D. Null hypothesis:u=30 Alternative hypothesis:u>30
Explanation:
The null and alternative hypotheses are hypotheses test made to decide on the value of a population parameter using sample data. They are statements that are mutually exclusive(only one can be true). Therefore the null hypothesis which is the hypothesis being tested becomes true if the alternative hypothesis(everything else that is not the null hypothesis) is false. The null hypothesis assumes that the researcher is wrong as in the above statements while the alternative hypothesis states that the researcher is right.
Answer:
Step-by-step explanation:
A symbol for a value we don't know yet. It is usually a letter like x or y.
Example: in x + 2 = 6, x is the variable.
Why "variable" when it may have just one value? In the case of x + 2 = 6 we can solve it to find that x = 4. But in something like y = x + 2 (a linear equation) x can have many values. In general it is much easier to always call it a variable even though in some cases it is a single value.
Answer:
Option A
Step-by-step explanation:
The unit volume explains it all.
Volumes are measured in units of length cubed. This also is the volume occupied by unit cubes.
By unit cubes, I meant, view the photo above
The volume of an object's says, how many of these cubes will fill that object.
It may not necessarily by a whole number.
So, the answer is Option A
