It is important to conduct multiple trials because _____.
Lubov Fominskaja [6]

Answer:

B. it makes your results more convincing

Step-by-step explanation:

A scientific experiment involves the replication and repetition of the experiment. Repetition or conducting the multiple trials of the experiment is very crucial for a scientific experiment.

The experiment is performed to understand and explain the natural phenomenon and the repetition of the experiment ensures that the results obtained from these trials are efficient either to support the hypothesis or to disprove the hypothesis.

Experimenting with multiple trials removes the chances of errors in the experiment, increases the efficiency and strengthens the results to prove or disprove the hypothesis. In other terms, it can be said that it makes the results more convincing.

Thus, Option-B is the correct answer.

What is the equation of the graphed linear model? y = x + Scatter plot on a first quadrant coordinate grid. The horizontal axis
Rasek [7]
If you have line on the scatter plot that is drawn through the points (1,3) and (9,11) then we will first calculate the slope:
m=(y2-y1)/(x2-x1)=(11-3)/(9-1) = 8/8 = 1
Then the interception with y-axis:
y=mx+b
3= 1*1 + b
3-1=b
b=2
The equation is:
y=x+2

A cylinder with a radius of 10ft has a volume of 2, 198.0013<br> What is the height of the cylinder
Svetach [21]

Answer:

~7 ft

Step-by-step explanation:

2,198.0013 = pi × 10^2 × h

h = 2198.0013 / (3.1416 × 100)

h = 6.996 ft ~ 7 ft

Solve for x<br><br> sin(x-20) = cos(x)
tatuchka [14]

Answer:

x=\frac{6480^{\circ \:}n+1980^{\circ \:}}{36}

x=\frac{36\pi n+11\pi }{36}

Step-by-step explanation:

We can use the identity: \cos \left(x\right)=\sin \left(90^{\circ \:}-x\right) to simplify this into:\sin \left(x-20^{\circ \:}\right)=\sin \left(90^{\circ \:}-x\right)

The identity sin(x) = sin(y)  -->  x=y+2\pi n,\:x=\pi -y+2\pi n, can be used to simplify this further:

x-20^{\circ \:}=90^{\circ \:}-x+360^{\circ \:}n    (Add 20 to both sides)

x=-x+360^{\circ \:}n+110^{\circ \:}    (Add x to both sides)

2x=360^{\circ \:}n+110^{\circ \:}    (Divide both sides by 2)

\frac{2x}{2}=\frac{360^{\circ \:}n}{2}+\frac{110^{\circ \:}}{2}    (Simplify)

x=\frac{6480^{\circ \:}n+1980^{\circ \:}}{36}    If required, we can convert this into radians:

x=\frac{36\pi n+11\pi }{36}
