Answer:
Algebra is a branch of mathematics that substitutes letters for numbers. Algebra is about finding the unknown or putting real-life variables into equations and then solving them. Algebra can include real and complex numbers, matrices, and vectors.
An equation is a mathematical sentence that has two equal sides separated by an equal sign. 4 + 6 = 10 is an example of an equation. ... For example, 12 is the coefficient in the equation 12n = 24. A variable is a letter that represents an unknown number.
Answer:
Option A
Step-by-step explanation:
Given the following question:
Mrs. Hernandez earns $35.60 an hour
One week she earned $854.40
To find the answer we divide 8,544 by 356
Mrs. Hernandez worked "24 hours last week" by using the first options equation, we can find that answer.
Hope this helps.

Answer:
Refer below
Step-by-step explanation:
a) a and b are the lower and higher values of the interval for which uniform distribution is defined.
Here a= 6 and b =10
b) Mean of the uniform distribution= (a+b)/2 = (6+10)/2 =8
Or int x (1/4) dx = x^2/8 = 8
c) Variance of the uniform distribution = (b^2-a^2)/12 = (100-64)/12
= 36/12 =3
Std dev = sq rt of 3 = 1.732
d) To find total area
PDF of the distribution = 1/(b-a) = 1/4, 6<x<10
Area = \int 6 to 10 of 1/4 dx
= x/4
Subtitute limits
= (10-6)/4 =1
So total area = 1
d)P(X>7) = int 7 to 10 of 1/4 dx = 3/4
e) P(7<x<9) = Int 7 to 9 of 1/4 dx = 2/4 = 1/2
Answer:
75 in³
x: 30
y: 20 35
Step-by-step explanation:
v = πr²h / 3
v = 3.14 * 3² * 8 / 3
v = 3.14 * 9 * 8 / 3
v = 75.36 in³
Rounded
v = 75 in³
---------------------
x increase by 10 for each step
y increases by 7.5 for each step
x: 0 10 20 30 40
y: 5 12.5 20 27.5 35
