On Saturday, 4/4 of the amount of people attended. On Friday, 3/4 of the amount on Saturday attended. We have 7 parts (3 from Friday and 4 from Saturday).
840/7 = 120.
Thus, 360 people attend on Friday and 480 on Saturday.
Answer:
Four pounds of strawberries costs $12: y=3x
Ben reads 5 novels per month: y=5x
Maya puts $4 into her bank account each week: y=4x
Answer:
Step-by-step explanation:
ok for the first one
the angle measurement of AE which is a straight line is 180
and the Angle measurement of ABC is 50 and because of vertical angles i know that the measurement of FBE is also 50 so all you do it
180 - 50 = 130
so you answer is C
-----------------------------------------------------------------------------------------------------------------------
now for the second one
it would be The corresponding angles Theorem which is option A
W= width
L= length= 2W-4
Perimeter= 70
FIND WIDTH:
P= 2(L + W)
P= 2L + 2W
substitute 2W-4 for L
70= 2(2W-4) + 2W
multiply 2 by all in parentheses
70= (2*2W) + (2*-4) + 2W
70= 4W - 8 + 2W
combine like terms
70= 6W - 8
add 8 to both sides
78= 6W
divide both sides by 6
13= W
FIND LENGTH:
substitute w=13 to find width
L= 2W-4
L= 2(13)-4
L= 26-4
L= 22
CHECK:
P= 2(L + W)
70= 2(22 + 13)
70= (2*22) + 2(13)
70= 44 + 26
70= 70
ANSWER:
length= 22 inches
width= 13 inches
Hope this helps! :)
Answer:
Alternate Hypothesis: The true weight of the piglets is greater than or equal to 39 lbs.
Step-by-step explanation:
Hypothesis testing is more like a binary process in which only one (Either Null or Alternate Hypothesis can be true) and we have to infer that whether our Null hypothesis is true or false.
The hypothesis testing involves following 4 general steps:
- State the 2 hypothesis by making sure that they don't overlap with each other
- Develop the analysis plan or any statistical method to know whether the Null hypothesis should be accepted or rejected
- Execute the developed plan and analyze the data
- In the end, after analyzing the data accept or reject the null hypothesis
As in the given question, if a number (X) is less than another number (Y) then it can't be less, equal or greater simultaneously.
