What is the scale factor of the dilation of triangle def? three-tenths three-sevenths seven-thirds 7
The scale factor of the dilation of triangle def is three-tenths i.e. 3/10
How to determine the scale factor of dilation?From the complete question, the corresponding sides are:
DE = 10
D'E' = 3
The scale factor k is then calculated using"
DE * k = D'E'
So, we have:
10* k = 3
Divide both sides by 10
k = 3/10
Hence, the scale factor of the dilation of triangle def is three-tenths i.e. 3/10

Show that (x − 9)(x − 1) ≡ x^2 − 10x + 9
We will expand the factored form of (x − 9)(x − 1) into the same form as x² − 10x + 9 to show they are equal.
Distribute and multipy out:
(x − 9)(x − 1)
x * x = x²
x * -1 = -x
x * -9 = -9x
-9 * -1 = 9
Add together:
x² + -x + -9x + 9
x² − 10x + 9
Use the Reflexive property:
x² − 10x + 9 = x² − 10x + 9 ✓

Ships arriving in U.S. ports are inspected by Customs officials for contaminated cargo. Assume, for a certain port, 20% of the ships arriving in the previous year contained cargo that was contaminated. A random selection of 50 ships in the current year included 5 that had contaminated cargo. Does the data suggest that the proportion of ships arriving in the port with contaminated cargoes has decreased in the current year
The value of the np is 10, and the value of the nq is 40 which is less than 5 also the hypothesis H0: p = 0.20 versus H1: p<0.20
What are the null hypothesis and alternative hypothesis?The null and alternative hypotheses are two generalizations about a population that are strictly contradictory. The null hypothesis can be denoted by H₀ and the alternative hypothesis can be denoted by H₁.
We have:
n = 50
p = 20% = 0.02
q = 1-p = 1- 0.02 = 0.08
[tex]\rm n_p = 50 \times 0.20 = 10\\\\\rm n_q = 50\times 0.80 = 40[/tex]
[tex]\rm n_q > 5\\\\\rm n_p > 5[/tex]
The conditions are verified for this test.
Null hypothesis H0: The number of ships arriving in ports with hazardous cargoes has remained constant.
Alternative hypothesis H1: The number of ships arriving in port with polluted goods has dropped.
H0: p = 0.20 versus H1: p<0.20
Thus, the value of the np is 10, and the value of the nq is 40 which is less than 5 also the hypothesis H0: p = 0.20 versus H1: p<0.20

(x-4)(x + 5) = 0x = 4, x = -5Their y intercept: (at y intercept, x will be 0)
y = (x-4)(x + 5)y = (0-4)(0 + 5)y = -20Answer:
x-intercepts : (4, 0) and (-5, 0)y-intercept : (0, -20)Step-by-step explanation:
Finding x-intercept(s)
The x-intercept's y-coordinate will be 0⇒ 0 = (x - 4)(x + 5)⇒ x = 4 and x = -5The x-intercepts are : (4, 0) and (-5, 0)Finding y-intercept
The y-intercept's x-coordinate will be 0⇒ y = 0² + 0 - 20⇒ y = -20The y-intercept will be (0, -20)A circle is centered at (−4, 9) and has a radius of 11.
What is the equation of the circle?
Answer:
(x +4)² +(y -9)² = 121
Step-by-step explanation:
The equation of a circle with center (h, k) and radius r is ...
(x -h)² +(y -k)² = r²
__
We are given that (h, k) = (-4, 9) and r = 11. When we put these values into the equation, it becomes ...
(x -(-4))² +(y -9)² = 11²
We can simplify this a bit to ...
(x +4)² +(y -9)² = 121

The probability of drawing a blue card first is 3/5 (3 blue cards out of a total of 5 cards). Then the probability of drawing a blue card again will be 2/4 (the blue card you drew first is removed so there are only 2 blue cards and 4 total cards). Now we multiply the probabilities together to get the probability of drawing a blue card, not replacing it, and then drawing another blue card = (3/5)(2/4) = 6/20 = 3/10.

Parenthesis (P):
(6 + 2) = (8)
Exponents (E):
none
Multiply/Divided (MD) left to right:
Multiply: 3 x 8 = 24
= 24 - 3 + 4 ÷ 2
Divided: 4 ÷ 2 = 2

Add/Subtract (AS) left to right:
Subtract: 24 - 3 = 21
= 21 + 2
Add: 21 + 2 = 23
A hotel with 80 rooms has 45 for doubles
and 35 singles. Singles can be booked in
any room, but reservations for two or
more people must be booked in double
rooms.
Let x be the number of single reservations and y
the number of reservations for two or more.
Which system of inequalities represents this
situation?
Click on the correct answer.
x ≥ 35 x + y ≤ 80
y ≤ 45 x + y ≤ 80
x≤ 35 x+y≤ 80
y≥ 45 x + y ≤ 80
Answer:
y ≤ 45
Step-by-step explanation:
First y must be less than or equal to 45.
y ≤ 45 x + y ≤ 80
And total number of reservations cannot exceed 80:
x + y ≤ 80.

Answer:
20%
Step-by-step explanation:
Given/To Find:
A $52.50 screen door is on
sale for $42. Find the percent
of discount on the door.
Solve:
Formula: Value 1 - Value 2 ÷ Original Value × 100
Hence we have:
52.50 - 42 = 10.5
10.5 ÷ 52.50 = 0.20
0.20 × 100
=20%
Check Answer:
52.50 × 20% = 10.5
52.50 - 10.5 = 42
Hence, the percent of discount on the door is 20%
