Last week Betsy made 80 on her quiz. This week she made 76. What is the percent of decrease in her score?
From the information given, she made an 80 the first week she took the quiz, then the next week she made a 76. Furthermore, we are asked to find the percent decrease.
Decrease means less. And less means subtraction in terms of Mathematics. So, hence, subtract 76 from 80 to find the percent decrease.
80 - 76 = 4
Now, just add the percentage behind the result.
4%
Therefore, the percent decrease in Besty's score is 4%.
is it a good idea to transplant organs from pigs into humans?
Answer:
um probably not
Step-by-step explanation:
have a great day...thanks for points ig :)
Answer:
no
Step-by-step explanation:
transplanting any animal organs into humans propose risk due to potential diseases and the probability that human bodies will reject the organs. if you think about it, humans can reject organs from other humans, so it doesn't sound likely that humans will accept another specie's.

Answer:
g(x) = 14x +7g(x) = 7x -18g(x) = -7x -16g(x) = 21x +17Step-by-step explanation:
The transformations of interest here are ...
g(x) = b·f(x) . . . . vertical scaling by a factor of bg(x) = f(-x) . . . . . reflection across the y-axisg(x) = f(x -h) +k . . . translation h units right and k units up1. The transformation parameters are given as b=2, (h, k) = (0, -3). Then we have ...
f1(x) = 2f(x) = 2(7x +5) = 14x +10 . . . . . vertical stretch by 2
g(x) = f1(x -0) -3 = 14(x -0) +10 -3
g(x) = 14x +7
__
2. (h, k) = (3, -2)
g(x) = f(x -3) -2 = 7(x -3) +5 -2 = 7x -21 +3
g(x) = 7x -18
__
3. The reflection gives us ...
f1(x) = f(-x) = 7(-x) +5 = -7x +5
Then the translation 3 left is (h, k) = (-3, 0).
g(x) = f1(x -(-3)) +0 = -7(x +3) +5 = -7x -21 +5
g(x) = -7x -16
__
4. The transformation parameters are b = 3 and (h, k) = (0, 2).
f1(x) = 3f(x) = 3(7x +5) = 21x +15 . . . . . . vertical stretch by 3
g(x) = f1(x) +2 = 21x +15 +2
g(x) = 21x +17

The sides of small squares are x and y, therefore the side of the big square is x + y.
The shaded region has an area:
(x + y)² - x² - y² = x² + 2xy + y² - x² - y² = 2xyb)
After the dimension changes the new side lengths are:
x - 2 and y + 2Since x and y are integers greater than 1, the minimum value of x is 2 (x = 1 doesn't work as we get negative value of x - 2) and same of y is 3 as y > x.
With this the smallest possible area of the shaded region is:

, among adults who regret getting tattoos, 14% say that they were too young when they got their tattoos. Assume that six adults who regret getting
tattoos are randomly selected, and find the indicated probability. Complete parts (a) through (d) below.
a. Find the probability that none of the selected adults say that they were too young to get tattoos
(Round to four decimal places as needed.)
The probability that none of the selected adults say that they were too young to get tattoos is 0.3512
What is Binomial probability distribution?The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
14% say that they were too young when they got their tattoos.
So, p= 0.14.
Six adults who regret getting tattoos are randomly selected
So, n=6.
Now, the probability that none of the selected adults say that they were too young to get tattoos.
P(X=0) = [tex]C_ {6.0} (0.14)^{0} (0.86)^{6}[/tex]
= 0.3512

What is an
equation of the line that passes through the points (6.1) and (72)
Solve the equation for the indicated variable.
P = 2L + 2W for L
Answer:
L = 1/2(P) - W
Step-by-step explanation:
Step 1: Flip the equation.
[tex]2L+2W=P[/tex]Step 2: Subtract 2W from both sides.
[tex]2L + 2W - 2W = P - 2W[/tex] [tex]2L = P - 2W[/tex]Step 3: Divide both sides by 2.
[tex]\frac{2L}{2} = \frac{P-2W}{2}[/tex] [tex]L = \frac{1}{2}P - W[/tex]Therefore, the answer is [tex]L = \frac{1}{2}P - W[/tex]

MODELING REAL LIFE: Faucet A
leaks at a rate of 21 liters per
day. Faucet B leaks at a rate
of 30 drips per minute.
Which faucet leaks at a
faster rate? (1 liter= 4000 drips)
Answer:
It would be Faucet A
Once we transfer liters to drips:
Faucet A= 84,000 drips
Faucet B= 30 drips
As you can tell, Faucet A is dripping way more than Faucet B.

Tony babysits his neighbor's children to earn extra money. He earns 10+5h dollars for every h hours he babysits. Last night, Tony babysat the neighbor's children for 2.5 hours.
Answer:
22.5$
Step-by-step explanation:
So first we can insert 2.5 into the equation so that we get the right answer:
10+5(2.5)
We can now simplify by doing 5 times 2.5 which is 12.5
We then add 10 to 12.5 to get our answer; 22.5$

Use the distributive property to remove the parentheses.
-3(-6y +3w-2)
Answer:
18y-9w+6
Step-by-step explanation:
-3*-6y=18y
-3*3w=-9w
-3-2=6
so, 18y-9w+6
Answer:
18y-9w+6
Step-by-step explanation:
The distributive property tells that because the -3 is outside of the parentheses, we multiply all values inside the parentheses by -3.
So, -6y * -3 is 18y because two negatives cancel out, 3w * -3 equals -9w, and -2 * -3 is 6, again because two negatives cancel each other out.
We put this all together, the parentheses and -3 is removed, and the expression becomes 18y-9w+6.

What is the answer to 4(-x + 4) =12
Hey there!
4(-x + 4) = 12
4(-x) + 4(4) = 12
-4x + 16 = 12
SUBTRACT 16 to BOTH SIDES
-4x + 16 - 16 = 12 - 16
CANCEL out: 16 - 16 because it gives you 0
KEEP: 12 - 16 because it helps solve for the x-value
NEW (temporary) EQUATION: -4x = 12 - 16
12 - 16 = -4
NEW EQUATION: -4x = -4
DIVIDE -4 to BOTH SIDES
-4x/-4 = -4/-4
CANCEL out: -4/-4 (the LEFT side) because that gives you 1
KEEP: -4/-4 (the RIGHT side) because it gives you the result of the x-value
x = -4/-4
x = 1
Therefore, your answer is: x = 1
