Draw the graphs of the lines below on the same grid to find the coordinates of the point of intersection. y + 5 = 2 x y = 7 − 2 x
Answer:
The point of intersection is (3,1)
Step-by-step explanation:
Manipulate these equations to achieve the form of y = mx + c
1) y + 5 = 2x
Y = 2x - 5
2) y = 7 - 2x
Y = -2x + 7
Point of intersection is (3,1) on the graph attached
To check algebraically:
2x - 5 = -2x + 7
4x = 12
X = 3
Substitute to get y
Y = 2x - 5
Y = 2 x 3 - 5
Y = 1
Therefore (3,1)
how many triangles can you make with side lengths of 17, 23, 13
Answer:
10 triangles
Step-by-step explanation:
Let’s consider three scenarios: an equilateral triangle, isosceles and scalene.
1. There are three possibilities for equilateral triangle: 13, 13, 13 17,17,17 23, 23, 23
2. There are 6 possibilities for a isosceles triangle:
There are three choices for the base and for the remaining two sides there are two choice, so 3 x 2 = 6
3. There is only one possibility for a scalene triangle:
Let’s use the triangle theorems to check:
Let the sides be 23,17 and 13. Since every other scalene triangle will have the same sides the SSS (Side-Side-Side) theorem states that any triangle with the same three sides is the same triangle (congruent).
Therefore when adding the three scenarios we will get 3 + 6 + 1 = 10 triangles that can be made.

Lara surveyed all of the 11th grade students at her school about the number of languages they speak and whether or not they have allergies. Here are her results:
Answer:
57.6% have allergies
42.4% have no allergies
Step-by-step explanation:
We only need to consider the students who speak two languages according to the question.
To find the percent with allergies, divide the number of students with allergies by the total number of students (that speak two languages).
19/33 = 0.5757 = 57.6%
To find the percent without allergies, divide the number of students without allergies by the total number of students (that speak two languages).
14/33 = 0.4242 = 42.4%
Check your work by adding the percentages to make sure they equal 100%
57.6 + 42.4 = 100

The area of the kitchen is 300 square feet. How many square feet is the entire house? Record your answer in the box.
Answer:
2,000 square feet
Explanation:
If the kitchen is 300 square feet, we can divide that by the percentage(15%). We get the answer 20, which will be our conversion factor!
Now, we multiply this conversion factor by all the other percentages(without decimals)
5 x 20 = 100
20 x 20 = 400
30 x 20 = 600
15 x 20 = 300
30 x 20 = 600
Now we add up all of these factors and get the answer :D
100 + 400 + 600 + 300 + 600 = 2,000 square feet

At a family reunion, family members are given a choice of swimming at the lake or going on a hike. The family
constructed the following frequency table to analyze the data.
Lake
Hike
Total
Children
6
Adults
9
Total
14
38
15
What does the relative frequency of represent in the situation?
X
Out of all the children, 15 prefer the lake.
Out of all the children, 15 prefer a hike.
Out of all the family members that prefer a Mike, 15 are children.
Out of all the family members that prefer the lake, 15 are children.
The relative frequency of 15/24 for this considered situation represents the situation given by: Option C: Out of all the family members that prefer a lake, 15 are children.
How to find the relative frequency?Relative frequency is the ratio of the considered sub group's count to the total count. (so its frequency of the considered sub group relative to the total frequency). (subgroup being group defined by a row, or a column)
How to form two-way table?Suppose two dimensions are there, viz X and Y. Some values of X are there as [tex]X_1, X_2, ... , X_n[/tex] and some values of Y are there as [tex]Y_1, Y_2, ... , Y_n[/tex]
List them in title of the rows and left to the columns. There will be [tex]n \times k[/tex] table of values will be formed(excluding titles and totals), such that:
Value(ith row, jth column) = Frequency for intersection of [tex]X_i[/tex] and [tex]Y_j[/tex] (assuming X values are going in rows, and Y values are listed in columns).
Then totals for rows, columns, and whole table are written on bottom and right margin of the final table.
For n = 2, and k = 2, the table would look like:
[tex]\begin{array}{cccc}&Y_1&Y_2&\rm Total\\X_1&n(X_1 \cap Y_1)&n(X_1\cap Y_2)&n(X_1)\\X_2&n(X_2 \cap Y_1)&n(X_2 \cap Y_2)&n(X_2)\\\rm Total & n(Y_1) & n(Y_2) & S \end{array}[/tex]
where S denotes total of totals, also called total frequency.
n is showing the frequency of the bracketed quantity, and intersection sign in between is showing occurrence of both the categories together.
The given two-way frequency table is:
Lake Hike Total
Children 6
Adults 9
Total 14 38
Total of hike subgroup is 14, out of which children are 6, so adults going for hiking must be 14 - 6 = 8 as adults and children going for hiking together are 14 in counts.
So, we get:
n(Hike ∩ Children) = 8
Thus, the total of subgroup Adults is 9+8=17 = n(Adults)
Total of vertical total columns is: n(Children) + n(Adults) = 38
or, we get: n(Children) = 38 - 17= 21
Since total of children subgroup is:
n(Lake ∩ Children) + n(Hike ∩ Children) = n(Children)
Thus, we get:
n(Lake ∩ Children) + 6 = 21
n(Lake ∩ Children) = 21-6 = 15
Thus, sum of the 'lake' subgroup is:
n(Lake) = n( Lake ∩ Children) + n(Lake ∩ Adults)
n(Lake) = 15 + 9 = 24
Thus, the completed two-way table is:
Lake Hike Total
Children 15 6 21
Adults 9 8 17
Total 24 14 38
Now, we've to find what does 15/24 represents.
The division is done by 24, which is the total of "lake" subgroup.
And in that lake subgroup, we have:
n(Lake ∩ Children) = 15
Thus, 15/24 is the relative frequency of those children who prefer the lake, relative to total number of people who prefer lake.
Thus, the relative frequency of 15/24 for this considered situation represents the situation given by: Option C: Out of all the family members that prefer a lake, 15 are children.

Item 5 A six-sided number cube is rolled, and then a spinner with 5 equal sections labeled A through E is spun. What is the probability of rolling a number less than 4 and spinning a D? 115 110 215 710
Answer 1/10
Step-by-step explanation:
I took the quiz.
The probability of rolling a number less than 4 and spinning a D is 1/10 or 0.10. The correct answer is option B.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Since there are 6 sections on the number cube, the probability of rolling a number less than 4 is 3/6 or 1/2.
The spinner has 5 equal sections labeled A through E, so the probability of spinning a D is 1/5.
To find the probability of both events happening, we multiply the probabilities of each event:
(1/2) x (1/5) = 1/10
Therefore, the probability of rolling a number less than 4 and spinning a D is 1/10 or 0.10.

The sum of two complex numbers is −3 + 5i. If one of the complex numbers is 1−8i, which answer choice below is the other number?
Answer:
C
Solution
For a complex number written in the form a + bi, a is called the real part of the complex number and b is called the imaginary part. The sum of two complex numbers, a + bi and c + di, is found by adding real parts and imaginary parts, respectively, that is, (a + bi) + (c + di) = (a + c) + (b + d)i. Therefore, the sum of 2 + 3i and 4 + 8i is (2 + 4) + (3 + 8)i = 6 + 11i.
Choice A is incorrect and is the result of disregarding i and adding all parts of the two complex numbers together, 2 + 3 + 4 + 8 = 17. Choice B is incorrect and is the result of adding all parts of the two complex numbers together and multiplying the sum by i. Choice D is incorrect and is the result of multiplying the real parts and imaginary parts of the two complex numbers, (2)(4) = 8 and (3)(8) = 24, instead of adding those parts together.

Answer:
[tex]area \: of \: triangle \: = \frac{1}{2} b \times h[/tex]
The area of a triangle formula is A = 1/2 × b × h, where b is base and h is height.
What is the area of a triangle?The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.
Here,
The area of a triangle formula is 1/2× b × h, where b=base and h=height.
Example: Find the area of a triangle with base 12 units and height 3 units.
Now, area of a triangle = 1/2× 12 × 3
= 6 × 3
= 18 square units
Therefore, area of a triangle formula is A = 1/2 × b × h.
