Answer:

15

Step-by-step explanation:

When you see something like f (18), this means 18 needs to be plugged in for x

let's plug in 18

f (18) = \(\frac{2}{3} (18) + 3\)

Let's solve

(18 × 2) ÷ 3 = 12

12 + 3 = 15

f (18) = 15

DB will appear at outputs A, and B.

Step 1

D flip flop stands for a delay flip flop that produces output that is identical to input after a brief delay. The flip flop's input and next state are equal.

Z is an output, and x and x inputs.

x'y + xA = DA= A*

B* = x'B + xA

z=A (output is independent of input) (output is independent of input)

The next states are A(t+1) and B(t+1). We must provide the next state value to D of the D flip flop in order to obtain the next states A(t+1), and B(t+1) for A, B(present state). So the sequential circuit will be:

Step 2

To get the next state as A(t+1)= x’A + xA, B(t+1)= x’B + xA, we have to give them to DA, DB of D flip flop because for D flip flop whatever is given to DA, DB will appear at output A, B.

Answer:

143.25

Step-by-step explanation:

First, you know that 95.50 is an hour well it's 1 hour and 30 minutes( because 1 is the hour and the 5 is half of ten so the 5 would equal 30) so 95.50 divided into 2 is 47.75 so 95.50+47.75=143.25

Answer: 143.25

Step-by-step explanation:

Answer:

Your answer is -32

Step-by-step explanation:

First you add $220 and $12 together giving you $232

Then you subtract $76 from the $232 giving you $156

Then subtract $188 from $156 giving you a total of -$-32

Answer:

y = x + 60

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (20, 80) and (x₂, y₂ ) = (40, 100) ← 2 points on the line

m = \(\frac{100-80}{40-20}\) = \(\frac{20}{20}\) = 1

the line crosses the y- axis at (0, 60 ) ⇒ c = 60

y = x + 60 ← equation of line

The piecewise function for this problem is defined as follows:

B.

The function is a piecewise function, as the function has different definitions based on the input of the function.

The different definitions for the graph are given as follows:

To the left of x = 0, we have a linear function with intercept of 2 and slope of 2, hence it is given as follows:

y = 2x + 2, x ≤ 0.

To the right of x = 0, we have a linear function with intercept of 4 and slope of -4/3, hence it is given as follows:

y = -4/3x + 4, x > 0.

The smaller of the triangle’s two acute angles is 65 degrees

Less than 90 degrees is the acute angle measurement. Right angles are 90 degrees in length. Angles that are obtuse are more than 90 degrees. Discover the various sorts of angles and examples of each.

Given:

Angles in a triangle

\(sin (4x-5)^\circ= cos (3x+4)^\cir\)

Since, sin \(\theta\)= cos(90 - \(\theta\)),

cos(90 - (4x - 5 )) = cos(3x +4)

cos(85 - 4x) = cos (3x+4)

Cancel out the cosine functions to have:

85- 4x = 3x+ 4

81 = 7x

x= 11.57

Hence, the smaller of two acute angles is 11.57 degrees

Step-by-step explanation:

We get the following answers:

A) The least square regression line is:

yi = 88.73 - 2.827(xi)

B) The slope  is β₁ = -2.827 and The intercept is β₀ = 88.73.

C) e*₆ = -0.6964, final grade is below average grade.

E) It would not be reasonable since no of absence increases the score decreases, it works well for small no of absences but will not work for large number of absences since it may give absurd final grade.

we have Xi = No of absences

Yi = Final grade

The regression model is

Yi = β₀ +  β₁Xi + i

β₀ = y -  β₁x

we have n = 10, x bar = 4.5 , y bar = 76.01

cov(x,y) = -23.325 and var(x) = 9.1667

therefore,  β₀ = 88.73 and  β₁ = -2.827

A) Least square regression line is given by:

yi =  β₀+ β₁Xi

yi = 88.73 - 2.827(xi)

B) The slope  β₁ = -2.827 which means when no of absence is increased by 1 duty then the final grade will decrease by 2.827

The intercept  β₀ = 88.73 when there are 0 days absence the average grade is 88.73

C) Predicted graph for student who misses five class periods is

x = 5

y*5 = 88.73 - 2.827(5) = 74.5964

Hence for corresponding residual is:

e*₆ = 73.9 - 74.5964

e*₆ = -0.6964, final grade is below average grade.

D) please see graph

E) when student miss 15 class periods the final grade will be

X = 5

y* = 88.73 - 2.827(15)

= 46

It would not be reasonable since no of absence increases the score decreases, it works well for small no of absences but will not work for large number of absences since it may give absurd final grade.

Quantitative variables for this study include Neck Size, Weight, Length, and Bear. the correct option is a. Neck Size, b. Weight, d. Length, e. Bear.

In statistics, quantitative variables are those that are measured numerically. As a result, they're also referred to as numeric variables.

Because it is not feasible to weigh a bear in the woods, researchers caught and measured 54 bears, recording their weight, neck size, length, and sex.

They were looking for a way to use other, more quickly determined variables to estimate weight.

The following are quantitative variables for this study:

See there are 6 yellow and 2 red.

It will be 6:2

And if we simplify it further both of the numbers are multiples of 2.

Therefore:

The answer is option A). 3:1

Answer: B. 4 to 1

Step-by-step explanation:

green = (3/4) purple

Substituting the expression for green from the first conversion, we get:

yellow = (5/6) (3/4) purple

yellow = (5/8) purple

Finally, we can use the third ratio to convert purple to red:

5 purple = 2 red

purple = (2/5) red

Therefore, the ratio between yellow to red is 4 to 1.

Answer:

The top 2 are "neither", and the bottom one is supplementary

Step-by-step explanation:

I can't fill in the boxes myself, so basically, let me just explain what those terms mean for you.

A complimentary angle is a pair of 2 angles which add up to 90°.

A supplementary angle is a pair of 2 angles which add up to 180°.

And the neither is just none of the above. There is no changing the above definitions. 2 angles can't be supplementary if they add up to 179°, or 181°, etc.

Note that Option A is pairwise and is relatively prime.

If every pair of elements in a list of integers is relatively prime, the list is pairwise relatively prime. For example, the numbers 121, 122, and 123 are relatively prime pairwise (even though they are each composite).

You can tell if a set of numbers are relatively prime if they do not share a common factor other than ±

Looking at set a:
11, 15, 19

Writing their prime factorization

11 = 11

15 = 3 x 5

19 = 19, hence since any pair of these numbers does not have any common factor, hence they are relatively prime.

Looking at set b:

14, 15, 21
Writing their prime factorization, we have:

14 = 7 x 2
15 = 3 x5

21 = 3 x 7

15, and 21 share a common factor of 3 while

14 and 21 share a common factor of 7, therefore, they are NOT relatively prime.

Looking at set c)
12, 17, 31, 37
Writing their prime factorization,
12 = 3 x 2²
17 = 17

31 = 31

37 = 37

In this case, no pair of these numbers have any common factor. Hence they are relatively prime.

Looking at set d)

7,8,9, 11, spelling out their prime factorization

7=7

8=2³
9=3²
11=11

Thus, any pair of these numbers do not have a common factor, hence they are relatively prime.

Creating simultaneous equations for the problem:

Mass of solution A = a

Mass of solution B = b

a + b = 150 _____(1)

0.65a + 0.90b = 150×0.80

0.65a + 0.90b = 120 __(2)

From (1)

a = 150-b ____(3)

substitute (3) into (2)

0.65(150-b) + 0.90b = 120

97.5 - 0.65b + 0.90b = 120

0.25b = 120-97.5

0.25b = 22.5

b = 22.5/0.25

b = 90
