Answer:
d
Step-by-step explanation:
a slop is if its vertical dangle or across. If you place the 2 coordinates on the plot, you count the spaces between which is -2/5.
The answer to your problem 20 + 5 + 0.03 + 0.006 is -25.036
Answer:
The value of x is 7 ⇒ 1st answer
Step-by-step explanation:
* Lets revise a fact in the circle
- The two tangents drawn from a point out side the circle are equal
∵ RSTUV is circumscribed about a circle
∴ Each side of the pentagon is a tangent to the circle
- Look to the attached figure to know how we will solve the problem
- Each tangent divided into two parts
# RS = x + y
∵ RS = 8
∴ x + y = 8 ⇒ (1)
# RV = x + n
∵ RV = 12
∴ x + n = 12 ⇒ (2)
- Subtract (2) from (1)
∴ y - n = -4 ⇒ (3)
# ST = y + z
∵ ST = 12
∴ y + z = 12 ⇒ (4)
# TU = z + m
∵ TU = 15
∴ z + m = 15 ⇒ (5)
- Subtract (5) from (4)
∴ y - m = -3 ⇒ (6)
# UV = m + n
∵ UV = 9
∴ m + n = 9 ⇒ (7)
- Add (6) and (7)
∴ y + n = 6 ⇒ (8)
- Lets solve equation (3) and equation (8) to find y
∵ y - n = -4 ⇒ (3)
∵ y + n = 6 ⇒ (8)
- Add (3) and (8)
∴ 2y = 2 ⇒ divide two sises by 2
∴ y = 1
- Lets substitute the value of y in equation (1)
∵ x + y = 8 ⇒ (1)
∵ y = 1
∴ x + 1 = 8 ⇒ subtract (1) from both sides
∴ x = 7
* The value of x is 7
A fraction is a part of a whole.
The total number of guests at the wedding is 276.
<h3>What is a fraction?</h3>
A fraction is a part of a whole. It is expressed as a quotient, in which the numerator is divided by the denominator.
We have,
1/3 of the guests = beef
5/12 of the guests = chicken
69 of the guests = vegetarians
The fraction that chooses vegetarian is:
= 1 - 1/3 - 5/12
= (12 - 4 - 5) / 12
= 3/12
= 1/4
Now,
1/4 guest = 69
So,
The total number of guests at the wedding as a fraction can be considered as 1.
1/4 = 69
1 = 4 x 69
1 = 276
Thus the total number of guests at the wedding is 276.

According to the given expected value, it is found that Marcos' statement is correct.
-
The interpretation of the <em>expected value</em> is that <u>over a large number of trials, the average value will be close to the expected value</u>.
In this problem:
- The expected value is of $25.
- Hence, if many of the plans are sold, the average profit per plan will be of $25, and Marcos' statement is correct.
About Amaya's statement, among groups of 1,000 customers there can be variations, hence, she is incorrect.
