Step-by-step explanation:
127? I hope this is right!
Answer:
Thank you <3
about 15 thanks on your profile
Step-by-step explanation:
112 questions
127 thanks total
Average of 1 thank on each questions
that means 112 questions have 1 thank each
So 112 thanks
subtract the total thanks from the question thanks
127 - 112
15
You have received around 15 thanks on your profile, as its an average of 1 thank on each question which means it could always be more or less.
The ratio of two radii of two spheres is 15:8. If the surface area of larger sphere is 706.9 mm2, fine the surface area of the smaller sphere.
Answer:
201.1 mm²
Step-by-step explanation:
Smaller sphere = 8
Larger sphere = 15
Larger sphere surface area = 706.9 mm²
Smaller sphere surface area = x
Hence:
Since we are dealing with surface area
8²/15² = x/ 706.9
Cross Multiply
15² × x = 706.9 × 8²
x = 706.9 × 8²/15²
x = 201.07377778 mm²
x ≈ 201.1 mm²
Therefore, the surface area of the smaller sphere is 201.1 mm²

The slope of the line below is -4. Write the equation of the line in point-slope
form, using the coordinates of the labeled point. Do not use parenthesis on
the y-side.
(-2, 2)
Answer:
y - 2 = - 4(x + 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 4 and (a, b) = (- 2, 2 ) , then
y - 2 = - 4(x - (- 2) ) , that is
y - 2 = - 4(x + 2)
What is the value of x in the equation
-x =2 - 3x +6?
1) 8

What is the volume of a hollow ball whose other radius is 200m and inner radius of 100m? What is the mass if it is iron?
Solution :
Volume of ball = Volume of outer ball - Volume of inner ball
[tex]V = \dfrac{4\pi R^3}{3} - \dfrac{4 \pi r^3}{3}\\\\V = \dfrac{4\pi}{3}( R^3 - r^3 )\\\\V = \dfrac{4\pi}{3}( 200^3 - 100^3 )\\\\V = \dfrac{4\pi}{3}(2^3 - 1^3) \times 10^6\\\\V = 2.93 \times 10^7 \ m^3[/tex]
Now, density of iron is, d = 7300 kg/m³.
So, mass of iron ball is :
[tex]m = d\times V\\\\m = 7300\times 2.93 \times 10^7 \ kg\\\\m = 2.14 \times 10^{11}\ kg[/tex]
Hence, this is the required solution.

Javier and his family drove to see Javier's grandparents during summer vacation in 2006. Gas prices varied from place to place. The gas prices Javier saw advertised advertised during the trip are shown below. What is the difference between the mean and median gas prices in dollars?
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the required data to calculate the mean and the median are missing.
To solve this, I will assume the following values:
[tex]13, 18, 13, 14, 13, 16, 14, 21, 13[/tex]
[tex]n = 9[/tex]
The mean is calculated as:
[tex]Mean = \frac{\sum x}{n}[/tex]
[tex]Mean = \frac{13+ 18+ 13+ 14+ 13+ 16+ 14+ 21+ 13}{9}[/tex]
[tex]Mean = \frac{135}{9}[/tex]
[tex]Mean = 15[/tex]
To calculate the median;
Start by sorting the data
[tex]Sorted: 13, 13, 13, 13, 14, 14, 16, 18, 21[/tex]
[tex]n = 9[/tex]
The median is:
[tex]Median = \frac{n + 1}{2}[/tex]
[tex]Median = \frac{9 + 1}{2}[/tex]
[tex]Median = \frac{10}{2}[/tex]
[tex]Median = 5th[/tex]
The median is the 5th item on the list; i.e. 14
So:
[tex]Median = 14[/tex]
The difference (d) between the mean and the median is:
[tex]d = |Mean - Median|[/tex]
[tex]d = |15 -14|[/tex]
[tex]d = |1|[/tex]
Remove absolute bracket
[tex]d=1[/tex]
The difference in the mean and the median of the assumed dataset is 1

Mean is the average of a data set.
Find the Mean by adding all numbers and dividing by how many numbers there are in the data set.
19+4+12+4+x/5
Combine Like Terms.
39+x/5=11
Use random x values to determine x.
39+16=55

x=16
Insert x into the equation to make sure you're correct.

In a class of students, the following data table summarizes how many students passed
a test and complete the homework due the day of the test. What is the probability that
a student chosen randomly from the class did not complete the homework?
Answer:
3/16
Step-by-step explanation:
The total number of students = no. of students passed + number of students who failed.
i.e, 13+3=16
probability = 3/16 = 0.1875

Answer:

Step-by-step explanation:
So basically, there are 4 segments: 15-30, 30-45, 45-60, 60-75.
There is also a list of values.
If these values fall between 15-30, for example, it is considered a freqeuncy of 1.
If a second value also falls between 15-30, it is considered to then have a frequency of 2.
Every value that falls under a range of values, such as 15-30, is counted as a freqeuncy of 1.
So, lets look at 15-30.
There is a freqeuncy of 3.
This means that 3 values were in between 15 and 30,
Now, we need to know how many values were above 30.
This means we do not count values that are in the 15-30 segment.
However, we do want to look at the freqeuncy in 30-45, 45-60, and 60-75.
In 30-45 we have a frequency of 3.
In 45-60 we have a frequency of 2.
In 60-75 we have a frequency of 2.
To find the amount of values above 30, we must add these all together:
3+2+2
=
7
So 7 values have a price above 30!

Darnel and Lester took a fishing trip with their scout troop last weekend. Darnel caught 4
catfish and 8 trout. Lester caught 3 catfish and 6 trout. Did the boys catch the same ratio of
catfish to trout?
yes
no
Answer:
Yes, the boys caught the same ratio of catfish to trout.
Step-by-step explanation:
First, find the ratios of catfish to trout for both Darnel and Lester.
Darnel's ratio is 4:8, since he caught 4 catfish and 8 trout.
This can be simplified to 1:2 by dividing each number by 4.
Lester's ratio is 3:6, since he caught 3 catfish and 6 trout.
This can be simplified to 1:2 by dividing each number by 3.
So, both of their ratios are 1:2.
Yes, the boys caught the same ratio of catfish to trout.
What is the value of x?
K
83°
L
M
(9x + 40)
Answer:
This inscribed angle is half of the intercepted arc JL, so 2(83)= 9x +40.
166 -40 = 9x, x=14.
Step-by-step explanation:
The value of x in the given figure is 14 which we obtain by inscribed angle is half of the intercepted arc.
The inscribed angle is half of the intercepted arc.
83 = 1/2(9x+40)
Now let us find the value for x
83= 9/2x + 20
Subtract 20 from both sides to isolate the x variable
83-20=9/2x
63=9/2x
126=9x
Divide both sides by 9
14 is value of x
x=14

I made some brownies and cookies to sell for a local fundraiser. The cookies sold for $0.75 each and the brownies sold for $1.25 each. If I sold 51 baked goods and made $53.25 from the bake sale, which item’s sales made the most money? Cookies Brownies
Answer:
Brownies made the most money
Step-by-step explanation:
Let c = cookies
b = brownies
We sold 51 items so c+b = 51
Cookies are .75 and brownies are 1.25
.75c + 1.25 b = 53.25
We have 2 equations and 2 unknowns
c = 51-b
Substituting into the second equation
.75(51-b) + 1.25b = 53.25
Distribute
38.25-.75b +1.25b = 53.25
Combine like terms
38.25+.5b = 53.25
Subtract 38.25 from each side
38.25 +.5b -38.25 = 53.25 -38.25
.5b =15
Divide each side by .5
.5b/.5 = 15/.5
b = 30
Now find c
c =51-b
c = 51-30
c = 21
They sold 30 brownies and 21 cookies
30 brownies * 1.25 =37.50
21 cookies *.75 = 15.75
Brownies made the most money
A fair die is rolled once. Let A be the event of rolling an even number, and let B be the event of rolling a number greater than 3. Find A ∩ B
Answer:
A ∩ B = {4, 6}
Step-by-step explanation:
A die had 6 faces
S = {1, 2, 3, 4, 5, 6}
If A be the event of rolling an even number, then;
A = {2, 4, 6}
If B be the event of rolling a number greater than 3, then;
B = {4, 5, 6}
A ∩ B are the values that are common to both sets
A ∩ B = {4, 6}
