Answer:

$\frac{5}{7}$

Step-by-step explanation:

$\frac{20}{28}$ since they can be simplified in multiples of 4 makes the 20 become a 5 and the 28 become 7

making the outcome $\frac{5}{7}$ this cannot be simplified any more

Consider randomly selecting a student at a large university. Let A be the event that the selected student has a Visa card, let B

Tems11 [23]

Answer:

0.75

Step-by-step explanation:

Given,

P(A) = 0.6, P(B) = 0.4, P(C) = 0.2,

P(A ∩ B) = 0.3, P(A ∩ C) = 0.12, P(B ∩ C) = 0.1 and P(A ∩ B ∩ C) = 0.07,

Where,

A = event that the selected student has a Visa card,

B = event that the selected student has a MasterCard,

C = event that the selected student has an American Express card,

We know that,

P(A ∪ B ∪ C) = P(A) + P(B) + P(C) - P(A ∩ B) - P(A ∩ C) - P(B ∩ C) + P(A ∩ B ∩ C)

= 0.6 + 0.4 + 0.2 - 0.3 - 0.12 - 0.1 + 0.07

= 0.75

Hence, the probability that the selected student has at least one of the three types of cards is 0.75.

What can be concluded about the sequence 19, 15, 11,

Mariulka [41]

Option first and option second are correct because the common difference of the sequence is the same as the slope of the graph.

<h3>What is a sequence?</h3>

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

The question is incomplete.

The question is:

What can be concluded about the sequences 19, 15, 11, 7, . . . represented on the graph? Check all that apply.

The common difference of the sequence is the same as the slope of the graph.
The slope of the graph is –4.
The next term in the sequence is represented by point (4, 3).
f(x) = –4x + 19 represents the sequence.
An infinite number of points can be determined to follow this sequence.

The graph is attached to the picture please refer to the graph.

We have an arithmetic sequence:

19, 15, 11, 7,...

The first term is:

a = 19

Common difference d = 15-19 = -4

The nth term:

a(n) = 19 + (n-1)(-4)

a(n) = 19 -4n + 4

a(n) = -4n + 23

We can write above expression as:

f(x) = -4x + 23

Slope of the equation = -4

The correct options are:

The common difference of the sequence is the same as the slope of the graph.
The slope of the graph is –4.

Thus, an option first and option second are correct because the common difference of the sequence is the same as the slope of the graph.

A single tree produces about 2.6 × 10² lb of oxygen each year. The Amazon rainforest has about 3.9 X 10^11 trees.

Ymorist [56]

$(2.6\times10^2) \times (3.9\times10^{11}) = 1.014\times10^{14}$

$1.014\times10^{14}$ <---How much is produced by all the trees in a year.
They want how much each day so divide by 365

$\frac{1.014\times10^{14}}{365} = 2.77808\times10^{11}$
$2.77808\times10^{11}$ <---answer per day
