Answer 1

Answer:

12

Step-by-step explanation:

The average rate of change for f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ 1, 3 ] , then

f(b) = f(3) = 27 ← value of y from table for x = 3

f(a) = f(1) = 3 ← value of y from table for x = 1

average rate of change = [tex]\frac{27-3}{3-1}[/tex] = [tex]\frac{24}{2}[/tex] = 12

In a survey, 80 percent of those
surveyed had at least one brother or
sister. What fraction of those surveyed
had at least one brother or sister? Write
your answer in the simplest form.

Answers

Answer:

4/5

Step-by-step explanation:

If we are given this value as a percent we can simply turn that percentage into a fraction. 80% would be 8/10 but since the question wants the fraction in simplest form we can achieve this by dividing both the numerator and denominator by 2. This would give us 4/5, which if we divide the numerator by the denominator we get 0.80 which is 80%. Therefore, the fraction of those surveyed  that had at least one brother or sister is 4/5

Which function has the greater maximum value: f(x) = -3x2 + 6x + 4, or g(x),
the function in the graph?

Answers

Answer: f(x)

Step-by-step explanation:

The function g(x) has the greater maximum value. So, option (A) is the correct answer.

What is the graph of a function?

"The graph of a function f is the set of all points in the plane of the form (x, f(x)). We could also define the graph of f to be the graph of the equation y = f(x). So, the graph of a function if a special case of the graph of an equation".

For the given situation,

The function f(x) is expressed as -3x^2 + 6x +4

The function g(x) is shown in the graph.

Plot the function f(x) in the graph to compare with g(x).

The graph for f(x) is shown below.

The function f(x) is the decreasing function, so it has only a minimal value.

The function g(x) is the increasing function, so it has a maximum value.

Hence we can conclude that the function g(x) has the greater maximum value. So, option (A) is the correct answer.

Help meeeeee, i don’t understand

Answers

Answer:

To graph the equation, you need to find the slope and y-intercept.

y = mx + b

[slope-intercept formula; m is the slope, and b is the y-intercept]

y = 4x + −1

[given equation before being simplified]

y = 4x − 1

[given equation]

m = 4

b = (0, −1)

Proof:

m = [tex]\frac{rise}{run}[/tex] = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

x₁ = 0

x₂ = 1

y₁ = −1

y₂ = 3

m = [tex]\frac{3 - -1}{1 - 0}[/tex]

m = 4

b = (0, −1)

[the value for x₁ and y₁ equals the y-intercept: (0, 1)]

Which of the options is true?

Option A compares the IQR of both plots.

IQR is calculated using:

[tex]IQR = Q_3 - Q_1[/tex]

Where

[tex]Q_1 \to[/tex] Lower quartile

[tex]Q_2 \to[/tex] Upper quartile

From the attached plots, we have:

Republican

[tex]Q_1 = 170.5[/tex]

[tex]Q_3 = 356[/tex]

So:

[tex]IQR = 356 - 170.5[/tex]

[tex]IQR = 185.5[/tex]

Democratic

[tex]Q_1 = 181[/tex]

[tex]Q_3 = 367.5[/tex]

So:

[tex]IQR = 367.5 - 181[/tex]

[tex]IQR = 186.5[/tex]

We have:

[tex]IQR = 185.5[/tex] --- Republican

[tex]IQR = 186.5[/tex] --- Democratic

Hence, (a) is true

A bag contains n counters. one counter is blue and the rest are red. Two counters are taken at random from the bag. a) express, in terms of n, the probability that a counter of each colour is taken. Give your answer as a fraction. b) the probability that a counter of each colour is taken is 0.125. How many red counters are in the bag?

Answers

Answer:

A] Probability = 1/n ; B] Number = 8

Step-by-step explanation:

Total counters = n , Blue counter = 1 , Red counters (remaining) = n -1

A] Prob (One blue, & One red counter) = (Blue counter / Total counters) x (Red counters / Total remaining counters) = [1 / n] x [ (n -1) / (n-1)] = 1 / n

Alternative, Prob  (One red, & one blue) = (Red counter / Total counters) x (Blue counters / remaining counters) = [ (n-1) / n ] x [1 / (n-1) ]  = 1 / n

B] Prob (each color , a blue & red counter taken) = 0.125  {Given}

By A], this Prob = 1/n.

So, 0.125 = 1/n → n = 1 / 0.125 = 8

Kendra's charge per car in the toy store is $1.8.

What is the system of equations?

"Systems of equations, sometimes called simultaneous equations, are a group of relationships between various unknown variables that can be expressed in terms of algebraic expressions".

For the given situation,

Let the number of cars be 'x' and

The number of candy be 'y'

$5.00 for two cars and one piece of candy

$3.2 for one car and one piece of candy

System of the equation for the above case

Equation 1:

[tex]2x + y = 5[/tex]

Equation 2:

[tex]x + y = 3.2[/tex]

Subtract equation 2 from equation 1,

⇒ [tex]x=1.8[/tex]

On substituting x in equation 2, we get

⇒ [tex]y=3.2-1.8[/tex]

⇒ [tex]y=1.4[/tex]

Hence we can conclude that Kendra's charge per car is $1.8.
