Answer:
-8 and -7
Step-by-step explanation:
First, let's find the cubed version of each answer choice.
-12 and -11:
- -12 cubed = -1728
- -11 cubed = -1331
-20 and -19:
- -20 cubed = -8000
- -19 cubed = -6859
-15 and -14:
- -15 cubed = -3375
- -14 cubed = -2744
-8 and -7:
- -8 cubed = -512
- -7 cubed = -343
Therefore, the answer is -8 and -7.
Answer:
5 : 1
Step-by-step explanation:
From your second-grade memorization of multiplication tables, you recognize that 15 = 3×5, so you know 3 is a factor of both numbers in the ratio. To reduce the ratio to simplest form, you divide out all common factors:
15 : 3 = (15/3) : (3/3) = 5 : 1
Answer:
40
Step-by-step explanation:
First we need to subtract the 50 students enrolled in English class.
150 - 50 = 100
Next, let's add the mathematics students and the physics students.
80 + 60 = 140
Then we subtract the total amount of mathematics and physics students by the total number of students.
140 - 100 = 40
Therefore, there are 40 students who take both mathematics and physics.
48 degrees.
Subtract 180-99 = 81
Subtract 180-129 = 51
180 - 51 - 81 = 48 degrees
Answer:
hello your question is incomplete attached below is the complete question
answer :
H0 : <em> u </em>= 21.62 ( Null hypothesis )
H1 : <em> u</em> = 21.62 ( alternative hypothesis )
Step-by-step explanation:
Formulating hypothesis that can be used to determine whether the population mean rate at 5 CCF of residential water discharged by U.S public utilities differs from $21.62
H0 : <em> u </em>= 21.62 ( Null hypothesis )
H1 : <em> u</em> = 21.62 ( alternative hypothesis )
