Answer:
y = 6 at x = 5Step-by-step explanation:
It is assumed the question is about finding the minimum value as the given function has no maximum value, it is + ∞ as the coefficient of x² is positive
The minimum/maximum value of a quadratic function is the vertex, which is at:
x = -b/2aFor the given function y = x² -10x + 31, the vertex is:
x = - (-10)/2*1 = 10/2 = 5The value of y at this point is:

Answer:
This sampling technique is called cluster
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.

Find x if:
- B is between A & C;
-AB = x + 5;
-BC = 2(x-3); and
-AB ~= BC
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
Tyion has 4,000 dollars and wants to share it evenly with 19 friends. How much would they each receive?
Answer:
Each friend will receive 210.5 dollars.
Step-by-step explanation:
Total Amount Tyion has = 4,000 dollars
He wants to share evenly with 19 friends.
We need to find How much would amount each friend will receive.
We can found it by using formula:
Amount each friend received = Total Amount / Number of friends
Putting values in the formula and finding results:
Amount each friend received = 4000/19
Amount each friend received = 210.5 dollars
So, each friend will receive 210.5 dollars.

Complete the blank using h.
So, we have:
2y – 4x = h
Make y the subject
2y = 4x + h
Divide through by 2
y = 2x + h/2
By comparing y = 2x + h/2 and y = 2x – 5, we have:
h/2 = -5
Multiply by 2
h = -10
Hence, the value is -10

We have,
To find the conditional probability of selecting a cow given that the animal has 2 legs, we need to determine the number of 2-legged animals and the number of cows with 2 legs.
From the given information, we know that cows have 4 legs.
The probability of selecting a cow with 2 legs is 0, since cows do not have 2 legs.
Thus,

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°

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
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

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
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

d. x = 1
Answer
C. x=2
Step-by-step explanation:
This is due to 2(2) = 4

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.

A line is drawn through the points $(-2, 6)$ and $(-4, -2)$. What is the $y$-coordinate of the point where this line intersects the $y$-axis?
Answer:
This line intersects the y-axis at [tex]y = 14[/tex]
Step-by-step explanation:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept(point where the line intersects the y-axis).
To find the slope, we take two points, and the slope is given by the change in y divided by the change in x.
In this question:
Points (-2,6) and (-4,-2). So
Change in y: -2 - 6 = -8
Change in x: -4 -(-2) = -4 + 2 = -2
Slope: [tex]m = \frac{-8}{-2} = 4[/tex]
So [tex]y = 4x + b[/tex]
Now, we take a point, and find b.
Point (-2,6), which means that when [tex]x = -2, y = 6[/tex]. So
[tex]y = 4x + b[/tex]
[tex]6 = 4(-2) + b[/tex]
[tex]b = 14[/tex]
So this line intersects the y-axis at [tex]y = 14[/tex]

Answer:
136°Step-by-step explanation:
Since the trapezoid is isosceles, the angles J and M are supplementary and angles M and L are congruent, therefore:
∠J + ∠M = 180°∠J + ∠L = 180°7x + 2 + 25x - 14 = 180°32x = 192x = 192/32x = 6∠M = ∠L = 25*6 - 14° = 150° - 14° = 136°
Answer:
From the given figure we can see that :---
JK||ML, JK=ML and JM=KL
Therefore,
angle J+ angle L = 180°
[tex](7x + 2) + (25x - 14) = 180 \\ 32x - 12 = 180 \\ 32x = 192 \\ \boxed{x = 6}[/tex]
Now, we know that, angle M = angle L
Hence,
[tex]25x - 14 \\ =( 25 \times 6) - 14 \\ =150 - 14 \\ = \boxed{136}[/tex]
Angle M is 136°.
