If you would like to know the value of A, you can do this using the following steps:

3x^2 + 9x - 4 = 0
3x^2 + 9x = 4
<span>A(x^2 + 3x) = 4

</span>A = 3:
<span>3 * (x^2 + 3x) = 4
</span>3x^2 + 9x = 4

The correct result would be C: 3.

A political interest group wants to determine what fraction p ∈ (0, 1) of the population intends to vote for candidate A in the
mash [69]

Answer:

95% confidence interval for the true fraction p is (0.426, 0.488)

Step-by-step explanation:

Confidence Interval can be calculated using p±ME where

  • p is the sample proportion (\frac{457}{1000} =0.457
  • ME is the margin of error from the mean

and margin of error (ME) around the mean can be found using the formula

ME=\frac{z*\sqrt{p*(1-p)}}{\sqrt{N} } where

  • z is the corresponding statistic in 95% confidence level (1.96)
  • p is the sample proportion (0.457)
  • N is the sample size (1000)

then ME=\frac{1.96*\sqrt{0.457*0.543}}{\sqrt{1000} } ≈ 0.031

Then 95% confidence interval would be 0.457±0.031 or (0.426, 0.488)

How do you know whether two quantities x and y are proportional?
Triss [41]

Answer:

The correct answer is:

1. Every ratio yx for related pairs of x and y is equivalent.

Step-by-step explanation:

Proportion is defined as the relationship between two quantities. When one quantity changes the other is also changes.

For two quantities y and x when we say that both are proportional then t can be written as:

y∝x

Removing the proportionality symbol introduces a constant which is the ratio of y and x.

\frac{y}{x} = k

This ratio of y and x, i.e. k is equivalent for all related pairs of x and y.

Hence,

The correct answer is:

1. Every ratio yx for related pairs of x and y is equivalent.
