The expression below represents the distance between two points on a number line.
|-5 – 4|
Which number line shows the two points?
Answer:
A
Step-by-step explanation:
|-5 - 4|
The expression represents the absolute value of - 5 - 4 ;
-5 - 4 = - 9
|-5-4| = 9
Hence, the distance between the two points is 9.
Hence, the number line which shows the two points is A.

Shrinkage is the loss of inventory from causes other than normal use or sales. It is the difference between the inventory on the books and the amount of inventory actually available for use. Typical causes of shrinkage are theft, damage, fraud, counting error, administrative error.
A paint manufacturer discovers that the mean volume of paint in a gallon-sized pail is 1 gallon with a standard deviation of 0.05 gallons. The paint volumes are approximately bell-shaped. Estimate the percent of pails with volumes between 0.95 gallons and 1.05 gallons.
Answer:
Approximately 68%.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 1, standard deviation = 0.05.
Estimate the percent of pails with volumes between 0.95 gallons and 1.05 gallons.
0.95 = 1 - 0.05
1.05 = 1 + 0.05
So within 1 standard deviation of the mean, which by the Empirical Rule, is approximately 68% of values.
68.29% of pails have volumes between 0.95 gallons and 1.05 gallons.
Z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean, \sigma=standard\ deviation[/tex]
Given that:
μ = 1, σ = 0.05
[tex]For\ x=0.95:\\\\z=\frac{0.95-1}{0.05} =-1\\\\For\ x=1.05:\\\\z=\frac{1.05-1}{0.05} =1[/tex]
P(0.95 < x < 1.05) = P(-1 < z < 1) = P(z < 1) - P(z < -1) = 0.8413 - 0.1587 = 68.29%

Which of these equations has NO solution? A. 3 ( 2 x + 7 ) = 6 ( x + 4 ) − 3 B. 3 ( 6 x − 5 ) = 3 ( 6 x − 5 ) + x C. 8 ( x − 3 ) + 14 = 2 ( 4 x + 5 ) D. 13 x − 7 = 12 ( x − 1 ) + x + 5
Answer:
B ig
Step-by-step explanation:
A: 3(2x+7) = 6(X+4) - 3
<=> 6x+ 21 = 6x + 24 - 3 = 6x + 21
<=> 0 = 21 - 21 = 0
B: 3(6x-5)= 3(6x-5)+x
<=> 18x-15= 18x - 15 + x = 19x - 15
<=> 0 = x
C: 8(x-3) + 14= 2(4x+5)
<=> 8x - 24 + 14 = 8x - 10 = 8x + 10
<=> 0 = 0
D: 13x - 7 = 12( x - 1) +x + 5
<=> 13x - 7 = 12x -12 + x + 5 = 13x - 7
<=> 0 = 0

Step-by-step explanation:
what’s the value of x ?
Answer:
x=70
Step-by-step explanation:
Because these angles are on the opposite sides of each other, they have to add up to 180. This will make the equation 2x-5+45=180. Simplify this to get 2x+40=180. Subtract 40 from both sides to get 2x=140. Divide each side by 2 to isolate x. x=140/2. Simplify this to get x=70.

Is (x + 2) a factor of x + 6x2 + 3x – 10?
Answer:
no
Step-by-step explanation:
6x² + 4x - 10 in factored form is:
2(3x+5)(x-1)
Answer:
Assuming that you actually mean that if [tex](x+2)[/tex] is a factor of [tex]x^{3}+6x^{2}+3x-10[/tex], the answer is yes.
Step-by-step explanation:
We need to do long division of the polynomial to figure out if this is true. I would show it here, but it is extremely difficult to do so. (Maybe someone could help me.) When I factor it, it does not leave a remainder, so this is true.
[tex]x^{3}+6x^{2}+3x-10= (x+2)(x^2+4x-5)[/tex]
Another way one could figure this out is by graphing the equation [tex]x^{3}+6x^{2}+3x-10[/tex] on your graphing calculator or on just a graphing website, lake Desmos. The screenshot below shows the graph.
The polynomial will have a factor of [tex](x-c)[/tex] if the point [tex](0,c)[/tex] exists on the graph. The graph has the following three zeroes.
[tex](0,-2)[/tex], [tex](0, -5)[/tex], and [tex](0,1)[/tex]
As such, it has the three factors [tex](x-(-2))[/tex], [tex](x-(-5))[/tex], and [tex](x-1)[/tex].
Since [tex](x-(-2)=(x+2)[/tex], it is a factor of the polynomial.

Answer:
a.0
Step-by-step explanation:
The slope of any horizontal line is 0
Answer:
A, 0
Step-by-step explanation:
The slope of a line is Change in Y / Change in X. This line is parallel to X-axis, meaning the Y will always be the same. This means that the change in y is 0, meaning the slope is 0 / Change in X, which is 0.
Reggie needs 24 feet of rope to make a tire swing. He has 10 yards of rope. Is this enough for him to make his swing? Explain.
Answer:
8 yards < 10 yards
He has enough.
Step-by-step explanation:
1 yard = 3 feet
y yards = 24 feet
[tex]\frac{1}{3} :\frac{y}{24}[/tex]
y · 3 = 1 · 24
3y = 24
3y ÷ 3 = 24 ÷ 3
y = 8
24 feet = 8 yards
8 yards < 10 yards
- What is the volume of a square pyramid with height 15m and slant height 17m?
A 85 m2
B 320 m2
C 1280 m2
D 3840 m2
Answer:
c ) 1280 m^3
here,
slant height (s)= 17m
vertical height ( h)= 15m
length (a)= ?
so,
s^2 = (a/2)^2 + h^2
(17)^2 = (a/2)^2 + 15^2
64 = (a/2)^2
8^2= (a/2)^2
8×2 = a so a = 16
Now we know
volume of pyramid
= 1/3 × a^2 × h
= 1/3 × 16^2 × 15
= 1/3 × 256 × 15
= 1280 m^3

Answer:Cost each item is : Pass = $21 , Souvenir = 2x/3 = $14 , Burger = x/6 =$3.5 .
Step-by-step explanation:
Here we have , Danny brought $43.00 to the state fair. He bought a burger, a souvenir, and a pass. The burger was 1/4 as much as the souvenir, and the souvenir cost 2/3 the cost of the pass. Danny had $4.50 left over after buying these items. We need to find What was the cost of each item . Let's find out:
Let value of pass is x ! So , the souvenir cost 2/3 the cost of the pass i.e.
⇒
Now , The burger was 1/4 as much as the souvenir i.e.
