The graph of y= sin (x-3pi/2) is the graph of the y = sin(x) shifted in which direction?
Nutka1998 [239]

Answer:

y=\sin(x-\frac{3\pi}{2}) is the graph of  y=\sin x shifted to the right by \frac{3\pi}{2} units.

Step-by-step explanation:

The given function is

y=\sin(x-\frac{3\pi}{2})

The base function of this trigonometric function is y=\sin x

In general, the transformation y=\sin(x-k) will shift the graph of the base function, y=\sin x, k units to the right.

Therefore, y=\sin(x-\frac{3\pi}{2}) is the graph of  y=\sin x shifted to the right by \frac{3\pi}{2} units.

The average systolic blood pressure was found to be 140 mm for people who have high responsibility jobs, specifically investment
defon

Answer:

t = -1.428

Step-by-step explanation:

Average blood pressure among people with high responsibility jobs = u = 140 mm

Number of people sampled for the study = n = 51

Average blood pressure of the sample = x = 139 mm

Standard deviation of the sample = s = 5 mm

The claim is that practicing yoga decreases the blood pressure. So we have to test that after practicing yoga, the average blood pressure will be lesser than 140. Based on this we can formulate the null and alternate hypothesis as:

Null Hypothesis: \mu \geq 140

Alternate Hypothesis: \mu < 140

Since population standard deviation is not known, we cannot use z-distribution for this test. We are given the value of sample standard deviation, so t-test will be used for this case.

Test statistic is calculated as:

t=\frac{x-u}{\frac{s}{\sqrt{n} } }

Using the values in this formula gives us:

t=\frac{139-140}{\frac{5}{\sqrt{51}}}\\\\ t=-1.428

Therefore, the value of test statistic is -1.428

Which statement is true about vertical angles. 1 point Vertical angles are congruent if two lines are parallel. If vertical angl
Serhud [2]

Answer:

Vertical angles are always congruent.

Step-by-step explanation:

Vertical angles are formed when two straight lines intersect each other, thereby forming two pairs of opposite angles, which are called vertical angles. Thus, a pair of these vertical angles formed are congruent to each other. So therefore, if two angles are said to be vertical angles, it follows that they are congruent to each other.

Using the diagram attached below, we can see two straight lines intersecting each other to form two pairs of vertical angles:

<a and <b,

<c and <d.

Thus, <a is congruent to <b, and <c is congruent to <d.

Therefore, the standby that is true about vertical angles is that:

Vertical angles are always congruent.
