Answer:
n=2
Step-by-step explanation:
7+14 = 7+7*2
7*2=14
1,617 -7 =1,610
1,610: 14 = 115
Al numero 7 se le suma 115 veces el numero 14(que es lo mismo que 7*2)
115*14 = 1,610
7+1,610 = 1,617
Answer: The z-score = 2.46
Step-by-step explanation:
Given: sample size : n= 10
Population mean : 
population standard deviation : 
Sample mean : 
Formula to calculate z :
Substitute all values, we get
Hence, the z-score = 2.46
Answer:
a > b > c
Step-by-step explanation:
The longest side is the one that sees the angle with the biggest measure
The angles are shown in the image, the third angle is 75 degrees (because the sum of interior angle is equal to 180)
So the list of the sides in descending order is as follows :
a > b > c (a sees angle measure 75, b sees angle measure 70, and c sees angle measure 35)
13. Answer: n ≥ 108
<u>Step-by-step explanation:</u>
18 ≤ n ÷ 6
<u>×6 </u> <u> ×6 </u>
108 ≤ n → n ≥ 108
Note: The line under the inequality symbol represents a closed dot

14. Answer: x > -4
<u>Step-by-step explanation:</u>
-3x < 12
<u>÷(-3) </u> <u>÷(-3) </u>
x > -4 <em>Flip the inequality sign when × or ÷ by a negative </em>
Note: No line under the inequality symbol represents an open dot

Answer:
Let's define all the possible forms:
slope-intercept: y = a*x + b
point-slope: y - y1 = a*(x - x1) (where (x1, y1) is a point in the line)
standard form: a*x + b*y = c
then:
a) 7x + 5y = 8
This is in standard form.
b) y − 5 = 3*(x − 9)
This is in point slope form.
c) y = 7x + 9
This is in slope-intercept form.
d) 8x − 9y = −2
This is in standard form.
