The longest a blender can last and still be in the lowest 5% of life spans will be 4.6 years. The correct option is A.
What is a normal distribution?The z-score formula can be used to resolve issues with samples that have a normal distribution. The score of a measure X in a collection with mean and standard deviation is given by:
Z = ( X - μ ) / σ
The Z-score calculates the deviation of the measure from the mean in standard deviations. We glance at the z-score table after determining the Z-score to determine the p-value connected to it.
The likelihood that the measure's value is less than X, or the percentile of X, is represented by this p-value. The likelihood that the value of the measure is greater than X is obtained by deducting 1 from the value.
In this problem, we have that:
μ = 5.8, σ = 0.9
Only those on the 5th percentile or lower will be replaced. So the warranty is the value of X when Z has a value of 0.05.
The value of x will be:-
Z = ( X - μ ) / σ
-1.28 = ( X - 5.8 ) / 0.9
X = 4.6
Therefore, the longest a blender can last and still be in the lowest 5% of life spans will be 4.6 years. The correct option is A.

The price of a coat is reduced by 15% in a sale.
If the table originally cost £80, what is it’s sale price
Answer:
68
Step-by-step explanation:
The formula for this equation is %/100 x original cost. The equation then is 15/100 x 80. Cut the zero from the 80 and 100 making the equation 15/10 x 8. divide the 15/10 which is 1.5. The final equation is 1.5 x 8 which is 12. This isnt the answer this is the price reduction which means u also have to do 80 - 12 which means the final answer is 68

A triangle has the exterior angle measures(-9x+13), (-2x+3) and (-10x+8)
Find the value of X
Answer:
x = -16
Step-by-step explanation:
An exterior angle of a triangle is the angle formed when one side is extended.
The sum of all exterior angles is 360°
Since the 3 exterior angles are given in terms of x we can add them up, set the sum to 360 and solve for x
Adding we get
-9x + 13
-2x + 3
-10x + 8
_________
-21x + 24
_________
∴ -21x + 24 = 360
Subtract 24 from both sides:
-21x = 360-24
-21x = 336
Divide both sides by -21
-21x/-21 = 336/-21
x = -16

For ()=‾‾√, use the values of (144) and (169) to estimate the value of 155‾‾‾‾√.
The square root of 155 is estimate according to the following compound inequality:
12 < sqrt(155) < 13.
What is a compound inequality?A compound inequality is a combination of multiple inequalities, at least two, involving operations such as and and or, explained below.
The and operation between multiple sets is composed by the elements that belong to all the sets.The or operation between multiple sets is composed by the elements that belong to at least one of the sets.Hence one example of a compound inequality is:
a ≤ x ≤ b.
Which is read as follows:
x is greater or equal than a and less or equal than b.
For this problem, we have that:
12² = 144, hence sqrt(144) = 12.13³ = 169, hence sqrt(169) = 13.Considering that 155 is between 144 and 169, and the square root function is increasing over it's entire domain, the square root of 155 is estimate according to the following compound inequality:
12 < sqrt(155) < 13.

Find the circumference and area of the figure if each unit on the graph measures 1 centimeter. Round answers to the nearest tenth, if necessary. (5,3) (2,1)
The area and circumference of a circle is 40.8cm² and 22.6 cm respectively.
What is meant by a circle's circumference?
The distance along a circle's perimeter is referred to as its circumference. In other words, the circumference of a circle is equal to the length of a straight line formed by opening up the circle.AB = r = √(5-2)²+(3-1)²
r = √9 + 4
r = √13
r = 3.605
Determine the circumference
C = 2(3.14)(3.605)
C = 22.6394
Hence the circumference of the circle is 22.6 cm
Determine the area
Area = πr²
Area = 3.14 * 3.605 * 3.605
Area = 40.8cm²
Hence the area and circumference of a circle is 40.8cm² and 22.6 cm respectively.

Which equation does the graph of the systems of equations solve?
According to the equation does the graph of the systems of equations solve is B.
1/3x+1=2x-4 is correct.
What is Graph?A graph is a structure consisting of a group of items, some of which are "linked." The objects are mathematical abstractions known as vertices, and each pair of connected vertices is known as an edge.
According to the given data:It is evident from the graph that the two lines intersect at the location:
(3, 2).
To put it another way,
at x =3, y = 2
The point where two lines intersect is:
(x, y) = (3, 2) (3, 2).
Now,
x = 3 is the point of the x-coordinate
y = 2 is the point of the y-coordinate
Now, examine the equation, 1/3x+1=2x-4, to see if it contains the correct x-coordinate value.
(1/3)x + 1 = 2x -4
subtracting 1 from both side:
(1/3)x + 1 -1 = 2x -4 -1
We get:
(1/3)x = 2x -5
subtract 2x from both sides:
(1/3)x -2x = 2x -5 -2x
We get:
-(5/3)x = -5
on simplifying the equation we get:
x = 3
the value of x = 3
this show that the 1/3x+1=2x-4 is correct.

Skylar is the youngest of four siblings whose ages are consecutive integers. if the sum of their ages is 70, find skylars age
Answer: 16
Step-by-step explanation:
Let Skylar is x year old
Hence, they ages is (x+1), (x+2), (x+3)
Thus,
x+(x+1)+(x+2)+(x+3)=70
x+x+1+x+2+x+3=70

4x=64
Divide both parts of the equation by 4:
x=16
The age of Skylar is 16.
What is algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them. Variables are the name given to these symbols because they lack set values. We frequently observe constant change in specific values in our day-to-day situations. But the need to depict these shifting values is ongoing. These values are frequently represented in algebra by symbols such as x, y, z, p, or q, and these symbols are known as variables. In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let the ages of the siblings be x, x+1, x+2 and x+3.
and, the sum of the ages be 70.
So, x+ x+1 + x + 2 +x+ 3 = 70
4x + 6 = 70
4x = 70 - 6
4x = 64
x= 64/4

e) 1
f) -1
g) DNE

at x = 0 the function has a jumping discontinuity. therefore, the limits are different when coming from left or from right. and because of this difference, the general limit does not exist. the functional value at x = 0 is part of the curve coming from the left.

A triangle has three interior angle measures; x is the largest angle, y is the next largest angle, and z is the smallest angle.
The measure of the largest angle is 40 degrees less than the sum of the measure of the other two angles.
The largest angle is twice the smaller angle minus 30 degrees.
The sum of the triangle's interior angles is x + y + z = 180.
Which two equations represent the remaining angle relationships?
Select each correct answer.
x = y + z + 40
x, = , y, + , z, + 40
x=2z−30
x equals 2 z minus 30
x=30−2z
x equals 30 minus 2 z
x=y+z−40
x equals y plus z minus 40
x=y−z+40
The equations that represent the remaining angle relationships will be D. x=y+z−40
x equals y plus z minus 40
How to illustrate the information?It should be noted that the measure of the largest angle is 40 degrees less than the sum of the measure of the other two angles.
This will be x = y + z - 40.
Also, the sum of the triangle's interior angles is x + y + z = 180.
Therefore the correct option is D.
