Answer: <em>x=100</em>
Step-by-step explanation:
<em>Let's start by multiply 1/5 on both sides to cancel it out with the x</em>
<em>1/5x=20</em>
<em>(1/5) (1/5)</em>
<em>x=100</em>
<em></em>
<em>1/5 MULTIPLIED BY 20 CAN ALSO BE 5 TIMES 20!</em>
The data are reported in the attached table.
We define the null hypothesis H₀ as the statement that is believed true until we prove it wrong with the test.
We define the alternative hypothesis H₁ as the statement we want to conclude with our test.
The difference in graffiti before (B) and after (A) will be:
d = A - B.
If the graffiti declined, it means that A will be smaller than B, therefore d should be negative.
Therefore we can set:
H₀ : μd ≥ 0
H₁ : μd < 0
The equal sign would mean that the number of graffiti incidents remained constant, therefore it is part of the null hypothesis.
Therefore the correct answer is B) H₀: μd ≥ 0 versus <span>H₁</span>: μd < 0
Lets try to solve this problem using 2 equations, also,we will have bananas=b and pears =p
5b+3p= $3.80
2b+4p= $3.20 i will divide this equation by 2 and get
b+2p= $ 1.60 we subtract 2p from both side so i can find the cost for 1 banana
b+2p-2p=1.60-2p
b= $1.60-2p
I will replace the b in the first equation now,
5(1.60-2p)+3p=$3.80
8-10p+3p=3.80 solving for p
8-7p=3.80 we subtract 8 from both sides
-7p=-8+3.80
-7p=-4.20 we multiply both sides by (-1)
7p=4.20 we divide now both sides by 7
p=0.60 a pear cost 0.60 cents
a banana is b=1.60-2p, b=0.40 cents
Answer:
i belive it to be A
Step-by-step explanation:
because it does say 6 by 7 by 3 so i would add 3+7 it would give me ten so i belive it to be A. hoped this helped lmk if it did
Answer:
You can't be sure without an image.
Step-by-step explanation:
If one moves left or right, that's a horizontal translation.
If one moves up or down, it's a vertical translation.
A dialation is when the image gets smaller or bigger.
