how many triangles??

Answer:

11/2

Step-by-step explanation:

Given Mixed fraction is 51/2

Step 1: Multiply 5 by 2: 5 × 2 = 10

Step 2: Add 10 with 1: 10+1 = 11 (New numerator value).

Hence, the improper fraction is 11/2.

11/2 is 5 1/2 as a fraction.

Mixed fraction is a number contain whole number and a proper fraction.

Given:

Mixed fraction is 5 1/2

To convert mixed fraction into proper fraction:

To get the fraction from mixed number you just need to take the number standing alone, multiply with the denominator and add with the numerator and keep it on top with the denominator in place to turn it into a fraction.

Step 1: Multiply 5 by 2: 5 × 2 = 10

Step 2: Add 10 with 1: 10+1 = 11 (New numerator value).

Proper fraction is 11/2.

Therefore, 11/2 is 5 1/2 as a fractions.

Answer:

B- n = 1

Step-by-step explanation:

"For all the positive integers n" is a qualifying statement. The number used has to be positive and also must be an integer. Integers are whole numbers and their opposites, so basically no fractions and no decimals. Answer A is a fraction and C is a decimal and D is negative and a decimal. So they don't work for this problem.

The value is n to show that the first step in a proof by mathematical induction of for all the positive integers is 1.

Thus, option B is correct.

The conditions can be checked through the options.

The option C and D will be eliminated because the condition is for all the positive integers n but n is decimal here.

For n = 1/4, the solution will be in fractions.

So, it does not hold true for n= 1/4.

For n = 1

[tex]\dfrac{n(n + 1)(2n + 1)}{6}[/tex]

 =[tex]\dfrac{1(1 + 1)(2 \times 1 + 1)}{6}[/tex]

= 1

Thus, the value is n  to show that the first step in a proof by mathematical induction of for all the positive integers n is 1.

So, option B is correct.

Answer:

-x + 1 __________________________

Answer:

-1

Step-by-step explanation:

The slope is the change in y over the change in x. In this graph, the y-value decreases by 1 unit to the right, and the x-value increases by 1 unit. So, this means that the slope is represented as -1/1. This can then be rewritten as -1.

We know that this slope is negative because it decreases to the right. Positive slopes increase to the right.

Step-by-step explanation:

Probability of an event is its chance of . The probability that a student not liking mountains doesn't like beach is: Option b: 40.4%

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}}[/tex]

Where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

For the given case, from the table (image attached below), we can see that, there are total 94 students who do not like mountains. Now, out of those 94, there are 38 students not liking beach.

Thus, if A = a student not liking beach

B = not liking mountains,

Then ,

P(A|B) = P(A ∩ B)/P(B) = [tex]\dfrac{38/158}{94/158} = \dfrac{38}{94} \approx 0.404 = 40.4\%[/tex]

Thus, probability of a student not liking beach given that that student doesn't like mountains is 40.4% approx.

Answer:

x = 15

Step-by-step explanation:

Supplementary = 180 °

Add the numbers

[tex](2x + 20) + 130 = 180[/tex]

[tex]2x + 150 = 180[/tex]

Subtract 150 from both sides of the equation

[tex]2x+150- 150 =180 - 150[/tex]

Simplify

[tex]2x = 30[/tex]

Divide both sides of the equation by the same term

The mean number of calls for Sami is 2.25 calls per day and for Marta it is 2.5 calls per day

The person who made more calls per day is Marta.

Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the numbers / total number

Sami = 27 / 12 = 2.25 calls per day

Given :

To Find :

Solution :-

Here we are given two sides of rectangle . We know that the area of rectangle is ,

→ Area = side 1 * side 2

Substituting the respective values ,

→ A = (x-3)(x+5)

→ A = x(x+5) -3(x+5)

→ A = x² + 5x -3x -15

→ A = x² +2x - 15

Hence the area of the rectangle is x² +2x -15.
