Find x if:
- B is between A & C;
-AB = x + 5;
-BC = 2(x-3); and
-AB ~= BC
Answers
Answer:
The value of x = 11
Step-by-step explanation:
Given
B is between A and C.AB = x+5BC = 2(x - 3)[tex]{\displaystyle {\overline {AB}[/tex] ≅ [tex]{\displaystyle {\overline {BC}[/tex]Determining the value of x
As B is between A and C, so
[tex]{\displaystyle {\overline {AB}[/tex] ≅ [tex]{\displaystyle {\overline {BC}[/tex]
as
AB = x+5BC = 2(x - 3)so
x + 5 = 2(x-3)
x+5 = 2x-6
2x-x = 5+6
x = 11
Therefore, the value of x = 11

The question is incomplete. Here is the complete question.
m∠J and m∠Kare base angles of an isosceles trapezoid JKLM.
If m∠J = 18x + 8, and m∠M = 11x + 15 , find m∠K.
A. 1
B. 154
C. 77
D. 26
Answer: B. m∠K = 154
Step-by-step explanation: Isosceles trapezoid is a parallelogram with two parallel sides, called Base, and two non-parallel sides that have the same measure.
Related to internal angles, angles of the base are equal and opposite angles are supplementary.
In trapezoid JKLM, m∠J and m∠M are base angles, so they are equal:
18x + 8 = 11x + 15
7x = 7
x = 1
Now, m∠K is opposite so, they are supplementary, which means their sum results in 180°:
m∠J = 18(1) + 8
m∠J = 26
m∠K + m∠J = 180
m∠K + 26 = 180
m∠K = 154
The angle m∠K is 154°

Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
The population is divided into groups(by stores), and all elements of the groups(all customers at the stores are sampled), which is the characteristic of a cluster sampling.

A family of 4 is buying cell phones. Each phone costs x dollars if the family buys the super plan which costs $89 for
each family member. The total cost for each family member to have a phone with the super plan is $1,952
Part A
Which equation represents this situation?
O4(2 + 89) = 1,952
O (x + 89) + 4 = 1,952
4x + 89 = 1,952
O 4x(89) = 1,952
Part B
What is the cost, in dollars, of each phone?
Each phone costs $
Ya
Answers
Answer: See explanation
Step-by-step explanation:.
From the question, the equation to illustrate the above question will be:
4(x + 89) = 1952
We can then solve further to get the value of x which will be:
4x + 356 = 1952
4x = 1952 - 356
4x = 1596
x = 1596/4
x = 399
Each phone cost $399

A computer’s random number generator produces random integers from 1 to 50. What is the probability that the first 3 integers generated are single-digit numbers?
0.0058
0.0080
0.5120
0.5514
Answers
Answer:
0.0058
Step-by-step explanation:
Probability is defined as the ratio of the possible outcome to the total outcome. The number of single-digit numbers between 1 and 50 is 9 ( from 1 to 9). As such, the probability of generating a single digit integer is
P(single) = 9/50
The probability that the first 3 integers generated are single-digit numbers
= 9/50 * 9/50 * 9/50
= 0.18 * 0.18 * 0.18
= 0.005832
This may be approximated to 0.0058

Proportions and Percentages
A proportion is calculated as a division between two numbers. The result can be given as a decimal or as a percentage.
If we want to calculate the percent of a number N with respect to another number M, the formula is:
[tex]\displaystyle p=\frac{N}{M}*100\%[/tex]

324=4(3)2x
a. x=8
b. x=4
c. x=2
d. x = 1
Answers
Answer
C. x=2
Step-by-step explanation:
This is due to 2(2) = 4
then 3^4=81
81*4=324
The solution to equation [tex]324=4(3)^{2x}[/tex] is x = 2.
What is exponential function?An exponential function is a mathematical function of the following form:
[tex]f(x) = a^{x}[/tex]. where x is a variable, and a is a constant called the base of the function.
Given exponential equation
[tex]324=4(3)^{2x}[/tex]
[tex]4(3)^{2x}=324[/tex]
[tex]3^{2x} =\frac{324}{4}[/tex]
[tex]3^{2x}=81[/tex]
[tex]3^{2x}=3^{4}[/tex]
When bases are equal, power should be equal.
2x = 4
x = 2
Hence, the solution to equation [tex]324=4(3)^{2x}[/tex] is x = 2.
Option C is correct.

The system of equations y=-2x+3 and y=x is graohed. What is the solution to the system of equations
Answers
Answer:
The solution to this system of equations is y = 1, x = 1
Step-by-step explanation:
We know that...
(1) y = - 2x + 3
(2) y = x
Then we just substitute the value of x that we are given in equation (2).
And so we get....
y = -2x + 3
x = - 2x + 3
3x = 3
x = 1
From equation (2) we know that y = x, so since x equals 1 y is also 1. There for the solution to this system of equations is (1,1)
