Answer:
x ≥[tex]\frac{-5}{2}[/tex]
Step-by-step explanation:
step(i):-
Given inequality
3x + 7 ≥ x +2
subtracting '2' on both sides, we get
⇒ 3x + 7 -2 ≥ x+2-2
⇒ 3 x + 5 ≥ x
subtracting 'x' on both sides, we get
3x +5 -x≥ x-x
⇒ 3x +5 -x ≥ 0
⇒ 2 x + 5≥ 0
Step(ii):-
subtracting '5' on both sides ,we get
2 x + 5 -5 ≥ 0-5
⇒ 2 x ≥ -5
⇒ [tex]\frac{2}{2} x\geq \frac{-5}{2}[/tex]
Final answer:-
⇒ x ≥[tex]\frac{-5}{2}[/tex]
how to calculate area when you are given volume of 182m3 and height of 2.8m
Hey there!
We simply have to do 182/2.8, and you will get the area (65m^2).
We know that the formula for area is length x width, and the formula for volume is length x width x height. In the volume formula, we can see it can also be area x height to get volume. So, we know that area x height = volume, right? And in this equation, we are given volume and height. If V = ha, with V = volume; h = height; a = area, we can divide "h" on both sides, and we get V/h = a, or volume divided by height is area. To solve for the above equation, we can plug the numbers in the formula: 182/2.8 = a, or 65 = a.
Hope this helps! Have an amazing day, and remember, you've got this!
For a hypothesis test of H0: p = 0.35 against the alternative, Ha: p > 0.35, the z test statistic is found to be 2.45. What can be said about this finding?
a. The finding is significant at α = 0.05, but not at α = 0.01.
b. The finding is significant at α = 0.01, but not at α = 0.05.
c. The finding is significant at both α = 0.05 and α = 0.01.
d. The finding isn't significant at α = 0.05 and α = 0.01.
e. The finding is inconclusive because we don't know the value of p.
Answer:
c? sorry if it's wrong...
The correct statement is,
⇒ The finding is significant at both α = 0.05 and α = 0.01.
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that;
For a hypothesis test of H₀, p = 0.35 against the alternative,
And, Hₐ: p > 0.35, the z test statistic is found to be 2.45.
Now, We get;
P(z < 2.45) = 0.9929
Hence, Significant is,
⇒ 1 - 0.9929 = 0.0071
Thus, Significant at both 0.05 and 0.01 because both are greater than 0.0071.
So, The correct statement is,
⇒ The finding is significant at both α = 0.05 and α = 0.01.

Shop owner, if the hall is of a square shape and
has a perimeter of 400m
a.Rs 400.000
b.Rs 600 000
c. 528000 d.365000
Answer:
c. 528000
Step-by-step explanation:
The computation of the amount that need to be paid is shown below:
Let us assume the side of the square shaped hall be X meter s
So,
Perimeter = 4X
Now
4X = 400
X = 100m
Now
Area of the hall = 100 × 100 = 10000 sq. meter.
And,
The cost on total tiles is
= 10,000 × 48 = Rs. 480000
But, there is 10% damage has occurred that involved in the cost
So,
Total cost is
= Rs 480,000 + 10% of 480,000
= 480,000 + 48,000
= Rs. 5,28,000

Write an exponential function for each set of points.
(0 , 1024), (1,256), (2,64). (3 , 16) and (4 ,4)
Answer:
[tex]f(x)=(\frac{1}{4})^{x-b}[/tex]
Step-by-step explanation:
We are given that
(0,1024),(1,256),(2,64),(3,16)and(4,4)
From given data we assume an exponential function
[tex]f(x)=a^{b+x}[/tex]
where b and a are constant
[tex]f(0)=1024[/tex]
[tex]1024=a^b[/tex]...(1)
[tex]f(1)=256[/tex]
[tex]256=a^{b+1}[/tex]...(2)
Equation (1) divided by equation (2)
Then, we get
[tex]\frac{1024}{256}=\frac{a^{b}}{a^{b+1}}[/tex]
[tex]4=a^{-1}[/tex]
[tex]a=\frac{1}{4}[/tex]
Using the the value of a in equation (1)
[tex]1024=(\frac{1}{4})^{b}[/tex]
[tex]4^{5}=4^{-b}[/tex]
[tex]-b=5[/tex]
[tex]b=-5[/tex]
Therefore, the exponential function
[tex]f(x)=(\frac{1}{4})^{x-b}[/tex]
The function f(x) is a cubic function and the zeros of f(x) are -6, -3 and 1. The
y-intercept of f(x) is 90. Write the equation of the cubic polynomial in standard
form.
Answer:
[tex]P(x)=-5x^3-40x^2-45x+90[/tex]
Step-by-step explanation:
Equation of a Polynomial
Given the roots x1, x2, and x3 of a cubic polynomial, the equation can be written as:
[tex]P(x)=a(x-x1)(x-x2)(x-x3)[/tex]
Where a is the leading coefficient.
We know the three roots of the polynomial -6, -3, and 1, thus:
[tex]P(x)=a(x+6)(x+3)(x-1)[/tex]
Since the y-intercept of the polynomial is y=90 when x=0:
90=a(0+6)(0+3)(0-1)
90=a(6)(3)(-1)=-18a
Thus
a = 90/(-18) = -5
The polynomial is:
[tex]P(x)=-5(x+6)(x+3)(x-1)[/tex]
We must write it in standard form, so we have to multiply all of the factors as follows:
[tex]P(x)=-5(x^2+6x+3x+18)(x-1)[/tex]
[tex]P(x)=-5(x^2+9x+18)(x-1)[/tex]
[tex]P(x)=-5(x^3-x^2+9x^2-9x+18x-18)[/tex]
[tex]P(x)=-5(x^3+8x^2+9x-18)[/tex]
[tex]\boxed{P(x)=-5x^3-40x^2-45x+90}[/tex]
To ensure that the mass of an average grain of rock salt stays the same, what should you multiply the first factor 1.2 by so that 10 negative 2 becomes 10 negative 4
Answer:
Step-by-step explanation:
[tex]1.2 X 100=120.\\[/tex]
Answer:
The mass of an average grain of rock salt is 1.2 x 10^-2. In part A, you multiplied 10^-2 by 10^-2 to get 10^-4. So, multiply the first factor, 1.2 , by 10^2, or 100.
The first factor will then be 1.2 x 100 = 120.

B)

C)

D)

In the given triangle the measure of ∠Q is (B) 73.5°.
What is a triangle?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.So, let's use the Sine rule in the calculation as follows:
q/sin q = r/sin r15/sin q = 12/sin 50.1 (Cross multiply)12 × sin q = 15 × sin 50.1 (divide both sides by 12)sin q = 15 sin 50.1/12q = sin⁻¹(15 sin 50.1/12) ≈ 73.5° (Rounded off)Therefore, in the given triangle the measure of ∠Q is (B) 73.5°.

One of the vertices of △PQR is P(2, −1). The midpoint of PQ is M(3, 0). The midpoint of QR is N(5, 3). Show that MN || PR and MN = 1/2 PR.
The coordinates of Q are:
The coordinates of R are:
The slope of MN is:
The slope of PR is:
The line segments are (select)
MN =
PR =
Answer:
See the proof below
Step-by-step explanation:
Given the following coordinates
P(2, −1)
Midpoint of PQ M(3, 0)
We can get the coordinate point Q using the midpoint formula;
M(X,Y) = (x1+x2/2, y1+y2/2)
X = x1+x2/2
3 = 2+x2/2
6 = 2+x2
x2 = 6-2
x2 = 4
Y = y1+y2/2
0 = -1+y2/2
0 = -1 + y2
y2 = 0+1
y2 = 1
Hence the coordinate of Q is (4, 1)
Next is to get the coordinate of R
Given the midpoint of QR to be N(5, 3)
(5,3) = (4+x2/2, 1+y2/2)
5 = 4+x2/2
10 = 4+x2
x2 = 10-4
x2 = 6
1+y2/2 = 3
1+y2 = 6
y2 = 6-1
y2 = 5
Hence the coordinate of R is (6,5)
Given the coordinates M(3, 0) and N(5, 3)
Slope is expressed as:
m = y2-y1/x2-x1
m = 3-0/5-3
m = 3/2
Slope of MN = 3/2
Get the slope of PR
Given the coordinates P(2, −1) and R (6,5)
Slope of PR = 5-(-1)/6-2
Slope of PR = 5+1/4
Slope of PR = 6/4 = 3/2
Since the slope of MN is equal to that of PR, hence MN is parallel to PR i.e MN || PR
To show that MN = 1/2PR, we will have to take the distance between M and N and also P and R first as shown:
For MN with coordinates M(3, 0) and N(5, 3)
MN = √(x2-x1)²+(y2-y1)²
MN = √(5-3)²+(3-0)²
MN = √2²+3²
MN = √13
Get the length of PR where P(2, −1) and R (6,5)
PR = √(6-2)²+(5+1)²
PR = √4²+6²
PR = √16+36
PR = √52
PR = √4*13
PR = √4*√13
PR = 2√13
Since MN = √13
PR = 2MN
Divide both sides by 2
PR/2 = 2MN/2
PR/2 = MN
Hence MN = 1/2 PR (Proved!)
