What is the gradient?
notsponge [240]

Answer:

Gradient = 2

Step-by-step explanation:

Gradient of a line = Slope of the line

Since, slope of a line passing through two points (x_1, y_1) and (x_2,y_2) is given by,

Slope = \frac{y_2-y_1}{x_2-x_1}

Given line in the graph passes through two points (1, 0) and (2, 2)

Therefore, slope or gradient of the line = \frac{2-0}{2-1}

                                                                  = 2

Gradient = 2 will be the answer.

Records show that 12% of all college students are foreign students who also smoke. It is also known that 40% of all foreign coll
Sati [7]

Answer: the percent of the students at this university are foreign = 30%

Step-by-step explanation:

Given: Probability that college students are foreign students who also smoke: P(S|F)=0.12

Probability that foreign college students smoke P(S∩F)=0.4

The probability that the students at this university are foreign :

P(F)=\dfrac{P(S\cap F)}{P(S|F)}  [By conditional probability formula]

=\dfrac{0.12}{0.4}\\\\=0.3

Hence, the percent of the students at this university are foreign = 30%

A recent survey by the New Statesman on British social attitudes asked respondents if they believe that inequality is too large.
Reika [66]

Answer:

(a) The probability that in a a sample of six British citizens two believe inequality is too large is 0.0375.

(b) The probability that in a a sample of six British citizens at least two believe inequality is too large is 0.9944.

(c) The probability that in a a sample of four British citizens none believe inequality is too large is 0.0046.

Step-by-step explanation:

The random variable <em>X</em> can be defined as the number of British citizens who believe that inequality is too large.

The proportion of respondents who believe that inequality is too large is, <em>p</em> = 0.74.

Thus, the random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> and <em>p</em> = 0.74.

The probability mass function of <em>X </em>is:

P(X=x)={n\choose x}\ 0.74^{x}(1-0.74)^{n-x};\ x=0,1,2,3...n

(a)

Compute the probability that in a a sample of six British citizens two believe inequality is too large as follows:

 P(X=2)={6\choose 2}\ 0.74^{2}(1-0.74)^{6-2}\\=15\times 0.5476\times 0.00456976\\=0.03753600864\\\approx 0.0375

Thus, the probability that in a a sample of six British citizens two believe inequality is too large is 0.0375.

(b)

Compute the probability that in a a sample of six British citizens at least two believe inequality is too large as follows:

P (X ≥ 2) = 1 - P (X < 2)

              = 1 - P (X = 0) - P (X = 1)

             =1-[{6\choose 0}\ 0.74^{0}(1-0.74)^{6-0}]-[{6\choose 1}\ 0.74^{1}(1-0.74)^{6-1}]\\\\=1-[1\times 1\times 0.000308915776]-[6\times 0.74\times 0.0011881376]\\\\=1-0.00031-0.0053\\\\=0.99439\\\\\approx 0.9944

Thus, the probability that in a a sample of six British citizens at least two believe inequality is too large is 0.9944.

(c)

Compute the probability that in a a sample of four British citizens none believe inequality is too large as follows:

 P(X=0)={4\choose 0}\ 0.74^{0}(1-0.74)^{4-0}\\=1\times 1\times 0.00456976\\=0.00456976\\\approx 0.0046

Thus, the probability that in a a sample of four British citizens none believe inequality is too large is 0.0046.
