x² + x = 12
show the steps please
Answer:
x1 = -4
x2 = 3
Step-by-step explanation:
[tex]x^{2} + x = 12\\x^{2} +x-12=0\\x^{2} +4x-3x-12=0\\x*(x+4)-3(x+4)=0\\(x+4)*(x-3)=0\\x+4= 0 \\x-3=0\\x=-4 \\x=3\\x1=-4 \\x2=3[/tex]
Step-by-step explanation:
=> x² + x = 12
=> x² + x -12 = 0
=> x² + 4x - 3x -12 = 0
=> x ( x + 4)-3(x + 4) = 0
=> ( x + 4)(x-3)=0
=> x = 3 , -4

Boats A, B, C, and D are all the same distance from Boat O.
Answer:
α = 62°
β = 56°
gamma = 90°
Step-by-step explanation:
ΔAOB is isosceles, so m∠A = m∠ABO = 28
28 + 28 + m∠AOB = 180
m∠AOB = 180 - 28 - 28 = 124
β = 180 - 124 = 56
arcAB = 124
ΔBOC is isosceles. α = m∠BCO = 1/2(arc AB) = 1/2(124) = 62
∠D is inscribed in a semicircle
m∠D = gamma = 90°

A box in the shape of a triangular prism is painted for a project. Which formula would be used to find the lateral surface area of the triangular prism?
Answer:
LSA = (a+b+c)×h
Step-by-step explanation:
The formula that would be used to find the lateral surface area of the triangular prism = perimeter of base(P) × Height of prism(H)
Let us assume that three side of triangle are a, b, c and height of prism is h
Then lateral surface area of the prism can be LSA = (a+b+c)×h

If the ratio of beakers to test tubes in a lab is 3:8, and there are 64 test tubes, how many beakers are there?
64 + 64 = 128. 128 is 6/8
128 is 75%
[tex]\frac{75}{100} = \frac{128}{y}[/tex]
y should be 171 or 172
The number of beakers in the lab are 24.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given that, the ratio of beakers to test tubes in a lab is 3:8, and there are 64 test tubes.
Let the beakers be 3x and the number of test tubes be 8x
The number of test tubes =8x=64
x=8
So, the number of beakers =3x=24
Therefore, the number of beakers are 24.

A USA Today poll asked a random sample of
1012 U.S. adults what they do with the milk
in the bowl after they have eaten the cereal
Let be the proportion of people in the
sample who drink the cereal milk A
spokesman for the dairy industry claims that
70% of all US adults drink the cereal milk
Suppose this claim is true.
Find the standard deviation of the sampling
distribution of p
Answer: 0.0188
Step-by-step explanation:
Using the Central Limit Theorem, it is found that the standard deviation of the sampling distribution of p is 0.0144.
Central Limit TheoremBy the Central Limit Theorem, the sampling distribution of sample proportions of a proportion p in a sample of size n has mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex].In this problem:
Suppose that 70% of all US adults drink the cereal milk, hence [tex]p = 0.7[/tex].A sample of 1012 adults is taken, hence [tex]n = 1012[/tex].Then, the standard deviation is:
[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.7(0.3)}{1012}} = 0.0144[/tex]
The standard deviation of the sampling distribution of p is 0.0144.

The function f is defined by f(x) = x^2-2x-24
if f (x + 3) = x^2+kx-21, what is the value of k?
Step-by-step explanation:
my guess it's 4
(x+7) (x-3)
The value of k for which f(x + 3) = x^2+kx-21 for the considered function f(x) is found to be k = 4
How to evaluate a given mathematical expression with variables if values of the variables are known?You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.
It is given that:
[tex]f(x) = x^2 -2x - 24[/tex]
and [tex]f(x+3) = x^2 + kx - 21[/tex]
Putting x = x+3 in the definition of f(x), we get:
[tex]f(x+3) = (x+3)^2 -2(x+3) -24\\\\f(x+3) = x^2 + 6x + 9 -2x -6 - 24\\\\f(x+3) = x^2 + 4x -21[/tex]
Comparing it with [tex]f(x+3) = x^2 + kx - 21[/tex], we see that k is having value as 4 for the considered function.
Thus, the value of k for which f(x + 3) = x^2+kx-21 for the considered function f(x) is found to be k = 4

and because the ________________________________. Therefore, ABCD is a parallelogram because both pairs of opposite sides are parallel.
Answer:
The answer is "lengths of opposite sides are equal "
Step-by-step explanation:
The parallelogram is a four-sided one in parallel opposites and therefore opposite angles equal. Each quadrilateral is called a rhombus with equal sides, as well as a parallelogram that also has correct angles is recognized as a rectangle. Its flat form with 4 smooth edges is parallel on the other side, so that when the opposite sides were equal in length. That's why ABCD is also a parallelogram because the two sides are parallel.

In square units, what is the area of the blue sector in the figure above? Round to the nearest tenth.
Given:
A figure of a circle with radius 8. The central angle of the blue sector is 60 degrees.
To find:
The area of the blue sector.
Solution:
Area of a sector is:
[tex]A=\pi r^2\dfrac{\theta}{360^\circ}[/tex]
Where, r is the radius and [tex]\theta [/tex] is the central angle of the sector in degrees.
Putting [tex]r=8, \theta=60^\circ, \pi=3.14[/tex], we get
[tex]A=(3.14)\cdot (8)^2\cdot \dfrac{60^\circ}{360^\circ}[/tex]
[tex]A=(3.14) \cdot (64)\cdot \dfrac{1}{6}[/tex]
[tex]A=33.49333....[/tex]
Approximate the value to the nearest tenth.
[tex]A\approx 33.5[/tex]
Therefore, the area of the blue sector is about 33.5 sq. units.
In a tennis club the ratio number of junior members : number of senior members is
7 : 10. There are 18 more senior members than junior members. Find the total amount of club members.
Answer:
35 members
Step-by-step explanation:
In a tennis club the ratio number of junior members : number of senior members is 7 : 10
From the above ratio
Number of junior member = 7
Number of senior members = 10
There are 18 more senior members than junior members.
S = 18 + j
10 + 18 = 28 senior members
Hence,
Total number of members = 28 senior members + 7 junior members
= 35 members

At a recent meeting, the manager of a national call center for a major Internet bank made the statement that the average past-due amount for customers who have been called previously about their bills is now no larger than $20. Other bank managers at the meeting suggested that this statement may be in error and it needs to be tested. The file called Bank Call Center attached below, contains data for a random sample of 67 customers from the call center population. What should be conducted based on the sample data? Test using α = 0.10
Answer:
As the calculated z does not fall in the critical region we fail to reject H0 and conclude that there is sufficient evidence that the average past-due amount for customers who have been called previously about their bills is now no larger than $23.
Step-by-step explanation:
As the standard deviation for the past due amounts is 63
The sample size n= 67
1) Formulate the null and alternate hypothesis
H0: u ≤ 23 against the claim Ha: u > 23
2) The test statistics is
Z= x- u / σ/ √n
z= 20- 23/ 63/ √67
z= 0.00581
z= 0.006
3) The significance level ∝= 0.1
4) The critical value for ∝= 0.1 is Z > ±2.33
5) As the calculated z does not fall in the critical region we fail to reject H0 and conclude that there is sufficient evidence that the average past-due amount for customers who have been called previously about their bills is now no larger than $23.
