In California in 2000, the ballot included an initiative to add "none of the above" to the list of options in all candidate race

s. Prior to the election, a Field Poll indicated that support for the measure was 10% below opposition for the measure. The poll was a telephone survey of 1000 registered voters in California. According to the Field Poll, "The survey was completed by telephone in English and Spanish using random digit dialing methods." A spokesperson for the initiative was critical of the poll because only 1000 people were surveyed. He pointed out that there are 23.5 million registered voters in California. Is his criticism valid? Group of answer choices No, because the sample was randomly selected. Yes, because it is impossible for 1,000 people to be representative of 23,500,000 people. No, because he was a spokesperson for the initiative, so he is biased. Yes, because a telephone survey will not represent the opinions of those without telephones.

Answer:

No, because the sample was randomly selected.

Step-by-step explanation:

In this example, the main element that we need to focus on is the way in which the sample was determined. We learn that the sample was taken in California with 1000 people. However, this sample was random, and the survey was conducted in both English and Spanish. The fact that this was a random sample means that it is representative of the population. The size of the population does not affect the accuracy of a random sample.

Answer:

  16. a: (-90°, (4, 3)); b: (90°, (0, 3)); c: (-90°, (0, 0))

  17. a: (down, (4, -1)); b: (right, (4, 3)); c: (up, (5, 2))

Step-by-step explanation:

We don't know what notation you're used to seeing for rotations. Here. we'll use the form [degrees CCW, (center)]. (CW angles are negative.) In any rotation, the center is the point that is invariant (remains in the same place)

16.

a) The tail is invariant, so the rotation is (-90°, (4, 3)).

b) The tip is invariant, so the rotation is (90°, (0, 3)).

c) The origin is invariant, so the rotation is (-90°, (0, 0))

__

17.

a) The tail is invariant, so the arrow is pointing down with the tip at (4, -1).

b) The center is invariant, so the arrow is reversed. It is pointing right with the tip at (4, 3).

c) Point (2, 3) is invariant, so the arrow is pointing up with the center at (5, 0). The tip is at (5, 2).

_____

<em>Additional comment</em>

If you have trouble visualizing these rotations, you might find it useful to trace the arrow on a piece of (semi-)transparent medium (plastic or tracing paper) so that you can move it as required to match the descriptions in the problem statement. A pin, or a dot on your tracing, can serve to fix the center of rotation. A little hands-on never hurts in math and geometry.

Determine the projection of w onto u.
irina [24]

Answer:

A.6.2i-4.2 j

Step-by-step explanation:

We are given that

u=9i-6j

v=-3i-2j

w=19i+15j

We have to find the projection of w on to u.

The project of vector a on b

=\frac{a\cdot b}{\mid b\mid^2}b

w.u=(19i+15j)\cdot (9i-6j)=171-90=81

\mid u\mid=\sqrt{x^2+y^2}=\sqrt{9^2+(-6)^2}=\sqrt{117}

Using the formula

The projection of w on to u

=\frac{u\cdot w}{\mid u\mid^2}(u)=\frac{81}{117}(9i-6j)

The projection of w on to u=6.2i-4.2j

Hence, option A is true.

Please help me!!!! on question 11
marishachu [46]

Answer:

D)

Step-by-step explanation:

y=\frac{-3}{2}x-4

Coefficient of x is -3/2 and so multiply the whole equation by 2

2*y=2*\frac{-3}{2}x-2*4\\\\2y=-3x-8

3x + 2y = -8
