Construct phrase-structure grammars to generate each of these sets. a) {1ⁿ | n ≥ 0} b) {10ⁿ | n ≥ 0} c) {(11)ⁿ | n ≥ 0}

Answers

Answer 1

(a) This grammar starts with the start symbol S and generates a string of 1s by recursively applying the production rule S -> 1S. The production rule S -> ε is used to generate the empty string, which belongs to the language.

a) {1ⁿ | n ≥ 0}

The grammar to generate this set can be constructed as follows:

S -> 1S | ε

b) {10ⁿ | n ≥ 0}

The grammar to generate this set can be constructed as follows:

S -> 1A

A -> 0A | ε

This grammar starts with the start symbol S and generates a string of 1s followed by a string of 0s by applying the production rules S -> 1A and A -> 0A | ε. The production rule A -> ε is used to generate the empty string, which belongs to the language.

c) {(11)ⁿ | n ≥ 0}

The grammar to generate this set can be constructed as follows:

S -> 11S | ε

This grammar starts with the start symbol S and generates a string of 11s by recursively applying the production rule S -> 11S. The production rule S -> ε is used to generate the empty string, which belongs to the language.

Find the surface area of the prism. Round to the nearest tenth if necessary.

Answers

The surface area of the prism is 544 mm²

How to determine the surface area

The formula is given thus;

SA=2B+ph

Where

B = area of the base

p = perimeter of the base

h = height

B = 1/2 h(b1+b2)

B = [tex]\frac{1}{2} * 8 * (17 + 9)[/tex]

B = 108 mm²

Perimeter = sum of length of sides

Perimeter = 17 + 9 + 15

Perimeter = 41 mm

Surface area = 2 ( 108 ) + 41 ( 8)

Surface area = 216 + 328

Surface area = 544 mm²

Thus, the surface area of the prism is 544 mm²

Luiza wants to go on a popular talent TV show. In order to be accepted, her audition must get at least 60%
positive votes from the people in the crowd. She was afraid she will not get enough votes, so she made a
video of her act and showed it to 60 random people from the crowd before the show. 50% of the people
said they would vote for her.
Let's test the hypothesis that the actual percentage of positive votes among the crowd is 60% versus the
alternative that the actual percentage is lower than that.
The table below sums up the results of 1000 simulations, each simulating a sample of 60 votes, assuming
there are 60% positive votes.
According to the simulations, what is the probability of getting a sample with 50% positive votes or less?
Let's agree that if the observed outcome has a probability less than 1% under the tested hypothesis, we

Please help me this is very confusing

Answers

Answer:

If f(-x) = f(x), f is even and is symmetric about y

If f(-x) = -f(x), f is odd and is symmetric about the origin

If [tex]f(-x)\neq f(x)[/tex] and [tex]f(-x)\neq -f(x)[/tex], f is neither even nor odd and does not have symmetry

Step-by-step explanation:

As we discussed in one of the previous questions, if f(-x) = f(x), we have an even function. One basic example of an even function is x^2 since (-x)^2 = x^2. On the other hand, if f(-x) = -f(x), we have an odd function. One common example is x^3 since (-x)^3 = -x^3. What we have not been over yet is the symmetry of the functions. In order to do this, let's examine x^2 and x^3. x^2, which is an even function, is symmetric to the y-axis. The graph is a parabola that looks exactly the same on the left and the right of the y-axis.

On the other hand, x^3, which is an odd function, is not symmetric to the y-axis. On the other hand, it is symmetric to the origin. You can imagine that if you flipped y = x^3 across the origin, you would end up getting a graph that looks exactly the same.

A function that is neither even nor odd, meaning [tex]f(-x)\neq f(x)[/tex] and [tex]f(-x)\neq -f(x)[/tex], one that is not odd or even, has no symmetry. It is not symmetric about the y-axis or the origin.

[tex]2m = - 22[/tex]

[tex]m = \frac{ - 22}{2} [/tex]

[tex]m = - 11[/tex]

→ Answer B

Variable m cannot be equal to any of the values −2,4 as division by zero is undefined. Multiply both sides of the equation by (m − 4)(m + 2), the lowest common denominator of 4−m,m + 2.

−(2 + m) ×5 = (m −4 )( −3 )

To find the opposite of 2+m, find the opposite of each term.

(−2 −m) ×5 = ( m−4 )( −3 )

Use the distributive property to multiply −2−m by 5.

−10 −5m = ( m−4 )( −3 )

Use the distributive property to multiply m−4 by −3.

−10 −5m =−3m + 12

Add 3m to both sides.

−10 − 5m + 3m =12

Combine −5m and 3m to get −2m.

−10 −2m = 12

Add 10 to both sides.

−2m = 12 + 10

Add 12 and 10 to get 2.

−2m = 22

Divide both sides by −2.

m = 22 / -2

Divide 22 by −2 to get −11.

m = −11

Therefore, the correct option is "B".

The length of your school building is shown as 40 cm in a map. If the scale
is taken as 1 cm=Im to draw a map then what is the actual length of the school ?

Answers

The school building's actual length is 40 m.

How to estimate the actual length of the school building?

Length exists as a measure of distance. In the International System of Quantities, length exists as a quantity with dimension distance. In most systems of measure a base unit for length is selected, from which all other units exist derived. In the International System of Units system, the base unit for length exists as the meter.

Given: School building length is given 40 cm on the map

scale used is 1 cm = 1 m

The scale utilized exists 1 cm = 1 m

1 cm in map = 1 m in actual

⇒ 40 cm in map = 40 m in actual

School building length in map = 40 cm

Actual Length of the school building is 40 m

Therefore, the school building's actual length is 40 m.

Suppose the daily customer volume at a call center has a normal distribution with mean 4,900 and standard deviation 700. What is the probability that the call center will get fewer than 4,400 calls in a day

Answers

The probability that the call center will get fewer calls than 440 is 0.26115.

Given mean of 4900 and standard deviation of 700.

We have to calculate the probability that the call center will get fewer than 4400 calls.

Probability lies between 0 and 1.

μ=4900

σ=700

We can  apply z as well as t statistics because the sample size is not given.

We are applying z statistics.

P(X<4400)=0.5-P(4400<X<4900)

z=X-μ/σ

where μ= mean

σ=standard deviation

z=4400-4900/700

=-500/700

=-0.71

p value of -0.71 is 0.23885.

So the p value of calls less than 4400 is 0.5-0.23885=0.26115.

Hence the probability that the call center will get calls less than 440 is 0.26115.
