Answer: incorrect,
6r=72
Divide both sides by 6
R=12
Answer:
Brooke's solution is incorrect.
She has to DIVIDE 6 on BOTH sides, not subtract 6 from both sides.
6r = 72
6r/6 = 72/6
r = 12

A coin is tossed 7 times. What is the probability of getting all tails? Express your answer as a simplified fraction or a decimal rounded to four decimal places.
Answers
Answer:
0.0078125
Step-by-step explanation:
Probability of tail, p = 0. 5
Probability of getting all tails from 7 tosses :
P(tail) * P(tail) * P(tail) * P(tail) * P(tail) * P(tail) * P(tail)
0.5 * 0.5 * 0.5 * 0.5 * 0.5 * 0.5 * 0.5 = 0.0078125
We could also use the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - r)
n = 7 ; x = 7, p = 0.5,
P(x = 7) = 7C7 * 0.5^7 * 0.5^0 = 0.0078125

The median is a better center for this data since since that number is the common size of acres not the highest or lowest acre per 1000 residents

Find the value of x.
Answers
Answer:
45 degrees
Step-by-step explanation:
Before we start, it is important to know that the sum of all angles of a triangle adds up to 180. Since one of the angle measure is already given to us, 90, we can subtract this from 180.
180-90=90
This tells us that the two remaining angles will add together to equal 90. In addition, it also tells us that the two remaining angles are equal. This means we can divide 90 by 2, and it leaves us that x= 45 degrees.
You can see that this is a right triangle so one of the angles equals 90°. 180-90= 90°.
Now we can see the remaining two angles add up to 2x. So if we put all our work together 2x= 45°.
Divide both sides by 2 to get x alone
And we come to that x equals 22.5.
x= 22.5°

Erica can thoroughly analyze the company’s monthly credit card statements
in 80 minutes. It takes Alexa 2 hours to do the same job. One afternoon, Erica and Alexa start analyzing the company’s credit card statements together. Half an hour later, Mack, the new employee, joins them. If the three of them finish 15 minutes later, how long would it have taken
Mack to analyze the company’s monthly credit card statements on his own?
Answers
Answer:
240 minutes or 4 hours
Step-by-step explanation:
So if it takes Erica 80 minutes to analyze the company's monthly credit card statements, she will get 30/80 of it done in 30 minutes.
If it takes Alexa 2 hours to analyze the company's monthly credit card statements, she will get 30/120 of it done in 30 minutes.
Add 15 to each of the fractions because they analyze the company's monthly credit card statements with Mack for 15 more minutes.
So you have 45/80 and 45/120.
Now add both fractions by finding the lowest common denominator which is 240.
135/240 + 90/240 = 225/240
So Mack did the remaining 15/240.
Now to find how long it would take him to analyze the company's monthly credit card statements by himself divide 240 by 15 which is 16.
Then multiply
15 x 16 = 240
so it would take him 240 minutes or 2 hours.

Answers
Answer:
x = 0 and y = 4.
Step-by-step explanation:
The given equations are :
4x+2y=8 ...(1)
x+y=4 ...(2)
Multiply equation (2) by 2.
2x+2y=8 ...(3)
Subtract equation (3) from (1).
4x+2y-(2x+2y)=8-8
4x+2y-2x-2y=0
2x = 0
x = 0
Put the value of x in equation (2).
0+y=4
y = 4
So, the value of x and y are 0 and 4.

Which weighs more: a puppy that weighs 8.5 kilograms or a baby that weighs 11 pounds? Explain your reasoning.
Answers
Answer:
a baby weight more because the baby will grow and will weight more then a puppy
Step-by-step explanation:
Answer:
A puppy that weights 8.5 kilograms weighs more.
Step-by-step explanation:
A puppy that weights 8.5 kilograms weighs more. Why? Well if you convert the 11 pounds from the baby to kilograms it would equal about 5 kilograms. The puppy's weight in kilograms is 8.5 and its weight in pounds is 18.7, while the baby's weight in kilograms is 5 and it's weight in pounds is 11.
Puppy's Weight Kilograms: 8.5
Puppy's Weight Pounds 18.7
Baby's Weight Kilograms: 5
Baby's Weight Pounds: 11
Weight in Kilograms: Puppy: 8.5 > Baby: 5
Weight in Pounds: Puppy: 18.7 > Baby: 11
Therefore, the puppy is heavier.

y is inversely proportional to V1+x.
When x=8, y = 2.
Find y when x = 15.
Please help me with this real quick!
Answers
Answer:
y = 1.5
Step-by-step explanation:
Given y is inversely proportional to [tex]\sqrt{1+x}[/tex] , then the equation relating them is
y = [tex]\frac{k}{\sqrt{1+x} }[/tex] ← k is the constant of variation
To find k use the condition when x = 8, y = 2 , then
2 = [tex]\frac{k}{\sqrt{1+8} }[/tex] = [tex]\frac{k}{\sqrt{9} }[/tex] = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )
6 = k
y = [tex]\frac{6}{\sqrt{1+x} }[/tex] ← equation of variation
When x = 15, then
y = [tex]\frac{6}{\sqrt{1+15} }[/tex] = [tex]\frac{6}{\sqrt{16} }[/tex] = [tex]\frac{6}{4}[/tex] = 1.5
