Answer:

21 AED

Step-by-step explanation:

W know the cost of each kind of meat

Chicken = 4 AED

Beef = 3 AED

We also know how much of each we will be buying

Chicken = 3.6 kg

Beef = 2.2 kg

Multiply each price of meat by its respective weight, then add the products together for you final answer.

4(3.6) + 3(2.2) = 21

Answer:

4 schools

Step-by-step explanation:

Based on the box plot you have given above, the answer would be 20% of the total schools participated for 6 years or more. This is because the part of the box plot wherein it hits 6 years and above is 20%. Thus, if there are 20 schools, then the 20% of it would be 4. In conclusion, there are 4 schools that participated for 6 years or more.

Answer:

a) 25% of the students exam scores fall below 55.6.

b) The minimum score for an A is 84.68.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 61 and a standard deviation of 8.

This means that [tex]\mu = 61, \sigma = 8[/tex]

(a) What score do 25% of the students exam scores fall below?

Below the 25th percentile, which is X when Z has a p-value of 0.25, that is, X when Z = -0.675.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.675 = \frac{X - 61}{8}[/tex]

[tex]X - 61 = -0.675*8[/tex]

[tex]X = 55.6[/tex]

25% of the students exam scores fall below 55.6.

(b) Suppose the professor decides to grade on a curve. If the professor wants 0.15% of the students to get an A, what is the minimum score for an A?

This is the 100 - 0.15 = 99.85th percentile, which is X when Z has a p-value of 0.9985. So X when Z = 2.96.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]2.96 = \frac{X - 61}{8}[/tex]

[tex]X - 61 = 2.96*8[/tex]

[tex]X = 84.68[/tex]

The minimum score for an A is 84.68.

Answer:

6 hours

Step-by-step explanation:

speed = distance/ time

6000meters to km = 6000/1000= 6km

speed for the first race = 6/2

speed = 3km/hr

for the second race

speed = distance/time

3 = 18/time

cross multiply

3* t = 18

divide both sides by 3

t = 18/3

t = 6 hours

Answer:

Ronald will take 6 hours to complete the 18 km race if he maintains this speed.

Step-by-step explanation:

6000m in 2h = 6km in 2h

multiply by 3:

18km in 6h

Answer:

30

Step-by-step explanation:

Given:

The function is:

[tex]f(x)=6x[/tex]

To find:

The inverse of the given function, then draw the graphs of function and its inverse.

Solution:

We have,

[tex]f(x)=6x[/tex]

Step 1: Substitute [tex]f(x)=y[/tex].

[tex]y=6x[/tex]

Step 2: Interchange x and y.

[tex]x=6y[/tex]

Step 3: Isolate variable y.

[tex]\dfrac{x}{6}=y[/tex]

Step 4: Substitute [tex]y=f^{-1}(x)[/tex].

[tex]\dfrac{x}{6}=f^{-1}(x)[/tex]

Therefore, the inverse of the given function is [tex]f^{-1}(x)=\dfrac{x}{6}[/tex] and the graphs of these functions are shown below.

Note: The inverse function is [tex]g(x)=f^{-1}(x)[/tex].

Margin of error is 4.645% with 95% confidence that the mean number of hours all the residents of the city are watching news on television is 1.8 .

Data given :

A researcher surveyed 220 residents of a city about the number of hours they spend watching news on television each day. The mean of the sample was 1.8 with a standard deviation of 0.35 .

The researcher can be 95% confident that the mean number of hours all the residents of the city are watching news on television is 1.8 with what margin of error,

By formula of margin of error = [tex]M = 1.96 \times S / \sqrt{N} ,[/tex]

[tex]Margin \ of \ error, \ M = z \times \frac{s}{\sqrt{N}}[/tex]

z - represents the z-value for the required confidence level .

s - represents the standard deviation of the sample .

N - represents the sample size .

Now, using the above information, compute the margin of error as -

[tex]\therefore \ Margin \ of \ error, \ M = z \times \frac{s}{\sqrt{N}} \\= 1.96 \times \frac{0.35}{\sqrt{220}}[/tex]

[tex]=0.04625 (rounded \ to \ 5\ decimal\ places) \\\\ =4.625\%[/tex]

Thus, the margin of error, M, is approximately 4.625% .
