Answer:
Since he hasn't read 70% of the book which is 35 pages, we need to know that 70% of what number is 35.
This is called a is over of, percent over 100 proportion.
If we place 70 over 100 and set that equal 35 over x we can cross multiply and divide to find the answer.
35 times 100 = 3,500
3,500 ÷ 70 = 50

Step-by-step explanation:
The times that a cashier spends processing individual customers' orders are independent random variables with mean 3.5 minutes and standard deviation 3 minutes. Find the number of customers n such that the probability that the orders of all n customers can be processed in less than 2 hours, is approximately 0.1. (Round your answer to the nearest integer.)
Answer:
26 customers
Step-by-step explanation:
First: determine the z score from standard normal probability table with an indicative area of 0.1
Z-score from probability table = - 1.28
mean = 3.5 minutes
std = 3 minutes
next determine the Z-score based on the information given in the question
Z = ( std - mean ) / processing time
= ( 3 - 3.5 ) / 2 = -0.25
Finally determine the number of customers
N = [tex](\frac{-1.28}{-0.25} )^2[/tex] = 1.6384 / 0.0625 = 26.21 ≈ 26 customers

Select the correct answer. Graph the given function and choose the key features that apply to its graph. y = x2 − 2x − 4
Answer:
Step-by-step explanation:
y = x^2 - 2x - 4
Convert to vertex form:
y = (x - 1)^2 - 1 - 4
y = (x - 1)^2 - 5
From this we conclude that there is a minimum vertex at (1, -5). It is a minimum because the coefficient of x^2 is positive.
It looks like a letter U and its symmetrical about the line x = 1.
You can plot 3 more points at say, where x = -2 ( and y = (-2)^2 - 2(-2) - 4)
and x = 4 ( y = 4^2 - 2(4) - 4 ) . Also where x = 0 and y = -4.
then draw the graph through these 3 points and the vertex.

How do you solve 3(15.9 - 3.9)
Step by step? I need help
Answer:
36
Step-by-step explanation:
3(15.9 - 3.9)
3 · (15.9 - 3.9)
3(15.9) - 3(3.9)
47.7 - 3(3.9)
47.7 - 11.7
36
Answer:
I believe the answer is 15
Step-by-step explanation:
15.9 - 3.9 (line up the decimals correctly)
then subtract it and you get 12.0
add 12.0 + 3 (under the 2)
12.0
+3
and you get 15 as your answer :)

3. Is XY Tangent to circle Z?
Y
12 X
(20
Z
18
Answer:
XY is a tangent
Step-by-step explanation:
Given
[tex]XY = 12[/tex]
[tex]WY = 20[/tex]
[tex]WZ = 8[/tex]
Required
Is XY a tangent?
XY is a tangent if:
[tex]WY^2 = XY^2 + WX^2[/tex]
Because XY should make a right angle at point X with the circle
Where
[tex]WX = 2 * WZ[/tex]
So, we have:
[tex]WY^2 = XY^2 + WX^2[/tex]
[tex]WY^2 = XY^2 + (2*WZ)^2[/tex]
[tex]WY^2 = XY^2 + (2WZ)^2[/tex]
[tex]WY^2 = XY^2 + 4WZ^2[/tex]
This gives:
[tex]20^2 = 12^2 + 4*8^2[/tex]
[tex]400 = 144 + 256[/tex]
[tex]400 = 400[/tex]
Yes, XY is a tangent

Step-by-step explanation:
If x = 7 units, y = 2 units, and h = 9 units, find the area of the trapezoid shown above using decomposition.
A.
81 square units
B.
99 square units
C.
63 square units
D.
72 square units
Answer:
A) 81 sq units
Step-by-step explanation:
Area of a trapezoid = one-half of height multiplied by the sum of the bases (the bases are the parallel sides)
the problem gives us all the values we need:
height = 9
smaller base is 'x' which is 7
larger bases is 2y+x which is 2(2)+7 = 11
A = 1/2·(9)(7+11)
= 1/2·9·18
= 9·9 which is 81 sq units
Which statement describes whether the function is continuous at x = 2?
O The function is continuous at x = 2 because f(2) exists.
O The function is continuous at x = 2 because lim f(x) exists.
X-2
The function is not continuous at x = 2 because f(2) does not exist.
The function is not continuous at x = 2 because lim f(x) does not equal f(2).
X-2
Answer: (b)
Step-by-step explanation:
Given
The function is given as
[tex]f(x)=\dfrac{x^2-12x+20}{x-2}[/tex]
Solving the function
[tex]f(x)=\dfrac{x^2-2x-10x+20}{x-2}\\\\f(x)=\dfrac{(x-2)(x-10)}{(x-2)}\\\\f(x)=x-10[/tex]
for [tex]x=2[/tex]
[tex]f(2)=2-10\\f(2)=-8[/tex]
The function is continuous at [tex]x=2[/tex] because [tex]\lim_{x \to 2} f(x)[/tex] exists.
If the limit exists at a point, then the function is continuous.

Evaluate f(x) = 2x - 7 when x = 8.
Answer:
9
Step-by-step explanation:
Substitute 8 in place of x
f(x) = 2*8-7
f(x) = 9
Answer:
9
Step-by-step explanation:
plug in 8 where x is so it would look like
2(8)-7 = 9
do 2 *8 first which is 16
then do 16-7 which gives you 9
