A consumer group is investigating the number of flights at a certain airline that are overbooked. They conducted a simulation to estimate the probability of overbooked flights in the next 5 flights. The results of 1,000 trials are shown in the following histogram.

Answers

Answer 1

Answer:

C. 0.446

Step-by-step explanation:

1-(0.114+0.332) = 0.446

The sum of the relative frequencies of the bars for 4 and 5 is 0.446.

Answer 2

The probability that atleast four of the next five flights will be overbooked is the sum of the probabilities of having 4 or 5 flights overbooked which is 0.446

The probability of having atleast 4 flights overbooked can be defined as :

P(X ≥ 5) = P(X = 4) + P(X = 5)

From the probability distribution displayed on the histogram :

P(X ≥ 5) = 0.332 + 0.114 = 0.446

Therefore, the probability of having atleast 4 flights overbooked ls 0.446

Ari thinks the perfect milkshake has 333 ounces of caramel for every 555 scoops of ice cream. Freeze Zone makes batches of milkshakes with 666 ounces of caramel and 888 scoops of ice cream.
What will Ari think about Freeze Zone's milkshakes?

Answers

Answer:

Ari will think that Feeze Zone makes milkshakes with too much caramel.

Step-by-step explanation:

First off I took 3 ounces of caramel to 5 scoops of ice cream, which makes a ratio of 3/5.

Freeze Zone makes milkshakes with 6 ounces of caramel, so I multiplied the 3 and the 5 by two to get 6 ounces of caramel for the ratio.

once you multiply the ratio by two it becomes 6/10 and the milkshakes that Freeze Zone makes are 6/8, so they have more caramel than Ari likes.

Two scientists are running experiments testing the effects of a vaccine on different control groups. The results are shown in the graph using the functions f(x) and g(x):
Which statement best describes the graph of f(x) and g(x)?

The graph of f(x) will eventually exceed the graph of g(x).
The graphs will both have their y-intercept equal to 5.
The graphs will both have their y-intercept equal to 2.

Answers

Answer:

The graph of g(x) will eventually exceed the graph of f(x).

Step-by-step explanation:

Since f(x) is linear and g(x) is exponential, g(x) will eventually exceed f(x). You can see it start to do so at the top of your graph.

Hope I help :)

Answer:

The graph of f(x) will eventually exceed the graph of g(x)

Step-by-step explanation:

Because g(x) has a steady growth rate, and f(x) is exponential (changes rapidly), f(x) will exceed the graph of g(x). This is can be seen happening at the top of the graph, where f(x) grows higher than g(x) at a faster rate.

Explain the Error: Alan says that two lines in the coordinate plane are perpendicular if and
only if the slopes of the lines are m and 1/m. Identify and correct two errors in Alan’s statement.

Answers

Answer:

Check the step-by-step

Step-by-step explanation:

To get the perpendicular you need to find the negative reciprocal, therefore, he is wrong as he did not switch the negative/positive sign in m & 1/m. Also, if m is a fraction like 5/3, the reciprocal would not be 1/m, it would be 3/5 as you flip the denominator and numerator.

Consider the equations shown: ax + by = ab & 2ax + 3by = 3b Which of these is the value of y in terms of a? Option 1 : y = 3a – 35 Option 2 : y = 2ab – 3b Option 3 : y = 9a – 35 Option 4: y = 3 – 2a

Answers

Answer:

Option 4: y = 3 – 2a

Step-by-step explanation:

Given the simultaneous equation;

ax + by = ab  ......... 1

2ax + 3by = 3b .....2

Required

Express y in terms of a

Using elimination method to eliminate x variable.

eqn 1 * 2 and eqn 2 *1 will give;

2ax + 2by = 2ab

2ax + 3by = 3b

Subtract

2by - 3by = 2ab - 3b

-by = 2ab - 3b

-by = b(2a-3)

-y = 2a-3

multiply through by -1

y = -2a + 3

y = 3-2a

Hence the value of y in terms of a is y = 3-2a

You can use the expression 2e+2w to find the perimeter of a rectangle where e is the length and w is the width. Interpret the coefficients of the terms.

Answers

Answer: The coefficient of terms is 2 represents length of 2 equal and opposite sides of rectangle.

Step-by-step explanation:

A rectangle is a 4 sides closed quadrilateral where opposite sides are equal .

So , length of one pair of opposite is represented by 'l'  [l= length]

Such that sum of these two sides = l+l=2l

The other pair of opposite sides s represented by 'w'  [w= width]

Such that sum of these two sides = w+w=2w

Perimeter is the sum of sides.

So, perimeter of rectangle = 2l+2w.

The coefficient of terms is 2 represents length of 2 equal and opposite sides of rectangle.
