which of the following tables shows a proportional relationship between x and y

Answer:

0.16

Step-by-step explanation:

The computation of the minimum no of usual smokers expected to get out of 20 adults is shown below:

Here the standard deviation is

[tex]= \sqrt{npq} \\\\= \sqrt{20\times 0.18 \times (1 - 0.18)}\\\\= \sqrt{20\times 0.18\times 0.82}\\\\= \sqrt{2.952}[/tex]

= 1.72

Now the minimum no of smokers is

[tex]= np - 2\times 1.72\\= 20 \times 0.18 - 3.44\\\\= 0.16[/tex]

Answer:

18.

Step-by-step explanation:

3 x 4 = 12, 12 times 12 equals 144, 6 - 4 equals 2, and 2 times 2 times 2 is 8, and 144 / 8 = 18.

Answer

The area of the shaded region under the standard normal curve is 0.4834.

Step-by-step explanation:

A random variable X is said to have a normal distribution with mean, µ and variance σ².

Then , is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is, Z  N (0, 1).

The distribution of these z-variates is known as the standard normal distribution.

Compute the area under the curve between -2.13 and 0 as follows:

Thus, the area of the shaded region under the standard normal curve is 0.4834.

Step-by-step explanation:

Number  of windows broken = 10% of 40

                                               [tex]= \frac{10}{100}*40\\= 4[/tex]

Answer:

4 windows are broken

Step-by-step explanation:

Answer:

Kindly check explanation

Step-by-step explanation:

Number of clubs = 13

Number of face cards = 12

Number of hearts = 13

Number of King's = 4

Number of reds = 26

Number of spade = 13

Number of 6's = 4

Total possible outcomes = total number of cards = 52

Probability = required outcome / Total possible outcomes

1.) P(A club) = 13 / 52

2.) P(face card or heart) =

p(face card) + p(heart)

12 / 52 + 13/52

= (12 + 13) / 52 = 25 /52

3.)

(A 6 and a spade)

4/52 * 13/52

= 52 / 2704

= 1/52

4.) A king

P(king) = 4 /52 = 1/13

5) A red

P(red) = 26 / 52 = 1/2

Answer:

the answer is 4882.50, hope this helps

Answer:

A) i) Null hypothesis; p ≤ 0.79

Alternative hypothesis; p > 0.79

ii) test statistic = 2

iii) P-value = 0.02275

B) i) Null hypothesis; p ≤ 0.70

Alternative hypothesis; p > 0.70

ii) test statistic = 2.5

iii) P-value = 0.00621

Step-by-step explanation:

A) We are given;

Population proportion; p = 79% = 0.79

308 of the 370 respondents use social media in their job search. Thus;

Sample proportion; p^ = 308/370 = 0.8324

Let's state the hypotheses;

Null hypothesis; p ≤ 0.79

Alternative hypothesis; p > 0.79

Formula for the test statistic is;

z = (p^ - p)/√(p(1 - p)/n)

z = (0.8324 - 0.79)/√(0.79(1 - 0.79)/370)

z = 0.0424/0.021175

z = 2

From online p-value from z-score calculator attached and using; z = 2; significance value = 0.05; and one tailed distribution, we have;

P-value = 0.02275

B) similar to answer A above, Population proportion; p = 70% = 0.70

But 281 of the 370 respondents use social media in their job search. Thus;

Null hypothesis; p ≤ 0.70

Alternative hypothesis; p > 0.70

Also; Sample proportion; p^ = 281/370 = 0.7595

Formula for the test statistic is;

z = (p^ - p)/√(p(1 - p)/n)

z = (0.7595 - 0.70)/√(0.70(1 - 0.70)/370)

z = 0.0595/0.023824

z = 2.5

From online p-value from z-score calculator attached and using; z = 2.5; significance value = 0.05; and one tailed distribution, we have;

P-value = 0.00621

Answer:

y=-1/4x - 2

Step-by-step explanation:

gradient of perpendicular lines is got by :M1M2= -1

y =4/3x + 6 rearrange 3y = 4x + 18

gradient is 4

4M2 =-1

M2 =-1/4

then is -2

hence y = mx + c is y = -1/4 x -2

[tex]f(8)=6\cdot8-4=48-4=44[/tex]

48-4=44

Step-by-step explanation: I had that q and got it right

Answer:

f(1) = 2

Step-by-step explanation:

Since f(x) = x^4 + 4 x^3 + 5 x^2 - 4 x - 4

When we evaluate this for x = k = 1, we replace x with the value 1 as shown below:

f(1) = 1^4 + 4 * 1^3 + 5 * 1^2 - 4 * 1 - 4 = 1  + 4 + 5 - 4 - 4 = 10 - 8 = 2

Answer:
