(2x + y) (2x + 2y) =
Answer: 4x^2 + 6xy + 2y^2
Step-by-step explanation:
(2x + y)(2x + 2y) =
2x*2x + 2x*2y + y*2x + y^2y =
4x^2 + 4xy + 2xy + 2y^2 =
4x^2 + 6xy + 2y^2
Answer:
4x² + 6xy + 2y²
Step-by-step explanation:
Given
(2x + y)(2x + 2y)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(2x + 2y) + y(2x + 2y) ← distribute both parenthesis
= 4x² + 4xy + 2xy + 2y² ← collect like terms
= 4x² + 6xy + 2y²
Find the slope of the line of best fit shown in the figure
Answer:
Slope of the line of best fit = -0.34868
Step-by-step explanation:
From the figure attached,
Coordinates of the points lying on the given line are (2, 3), (2, 5), (2, 6), (3, 5), (4, 3), (5, 4) and (7, 3)
By using the linear regression calculator,
Equation of the line of best fit → y = -0.34868x + 5.38816
Comparing this equation with, y = mx + b
Slope of the line of best fit → m = -0.34868
What is the standard deviation of a normal distribution who meet us 35 in which an X value of 23 has a Z score of -1.63
Answer:
7.362
Step-by-step explanation:
Given :
Mean = 35
Score, x value = 23
Zscore = - 1.63
Recall the Zscore formula :
Zscore = (X - mean) / standard deviation
-1.63 = (23 - 35) / standard deviation
-1.63 = - 12 / standard deviation
standard deviation * - 1.63 = - 12
Divide both sides by - 1.63
Standard deviation = - 12 / - 1.63
Standard deviation = 7.362

Answer:
Step-by-step explanation:
Jenny left her house at 8:00 AM and went to school at a speed of 2 2/3 mph her brother Jim left the house 4 minutes later and went to the same school. What must his speed be if he wants to keep the same distance between his sister and himself?
Answer:
2 and 2/3 mph
Step-by-step explanation:
The computation of the speed when he wants to keep the same distance is shown below:
Given that
Jenny left her house at 8:00AM
Went for a school at a speed of 2 and 2/3 mph
And, her brother left the house minutes later
So here the speed would be the same i.e. 2 and 2/3 mph

45 inch board cut into three pieces so that the second piece is 3 times as long as the first piece and the third piece is 5 times as long as the first piece . find the lengths of all three pieces
Answer:65
Step-by-step explanation:
Length of first, second and third piece are 5, 15 ,25 inch
Given that;
Length of board = 45 inch
Second cut is 3 times as long as the first piece
Third cut is 5 times as long as the first piece
Find:
Length of all three piece
Computation:
Assume;
Length of first piece = a
So,
Length of second piece = 3a
Length of third piece = 5a
So,
Length of first piece + Length of second piece + Length of third piece = Total length
a + 3a + 5a = 45
9a = 45
a = 5
So,
Length of first piece = a
Length of first piece = 5 inch
Length of second piece = 3a = 3(5)
Length of second piece = 15 inch
Length of third piece = 5a = 5(5)
Length of third piece = 25 inch

In 1-5, given: Two similar cylinders with heights of 8 and 5 respectively.
Answer:
1. The ratio of their diameters is 8/5 = 8 : 5
2. The ratio of their surface area is (8/5)²
3. The ratio of their volume is (8/5)³
4.The area of the base of the larger cylinder is 128 cm²
Step-by-step explanation:
Given that the two cylinders are similar, we have;
Two cylinders are similar when the ratio of their heights is equal to the ratio of their radii
Therefore, we have;
1. The ratio of the height of the two cylinders = 8/5 = The radio of their radii = r₁/r₂
The ratio of their diameter = D₁/D₂ = 2·r₁/2·r₂ = r₁/r₂ = 8/5
The ratio of their diameters D₁/D₂ = 8/5 = 8 : 5
2. The surface area of the cylinders = 2·π·r·h + 2·π·r²
Therefore, we have;
(2·π·r₁·h₁ + 2·π·r₁²)/(2·π·r₂·h₂ + 2·π·r₂²) = (r₁·h₁ + r₁²)/(r₂·h₂ + r₂²)
h₁ = h₂ × 8/5
r₁ = r₂ × 8/5
= (8/5)²(r₂·h₂ + r₂²)/(r₂·h₂ + r₂²) = (8/5)²
The ratio of their surface area = (8/5)²
3. The volume of the cylinder = π·r²·h
∴ The ratio of the volume = (π·r₁²·h₁)/(π·r₂²·h₂) = (8/5)³ × (π·r₂²·h₂)/(π·r₂²·h₂) = (8/5)³
The ratio of their volume = (8/5)³
4. The ratio of the area of the base of the larger cylinder to the area of the base of the smaller cylinder is (8/5)²
Therefore if the area of the base of the smaller cylinder is 50 cm², the area of the base of the larger cylinder = 50 cm² × (8/5)² = 128 cm²

In a class of 28 students, 21 have a brother and 9 have a sister. There are 7 students
who have a brother and a sister. What is the probability that a student chosen
randomly from the class has a brother and a sister?
1/4
because not a lot of students have both gender as siblings!
Answer:
Step-by-step explanation:
28 students in total
21 - 7 = 14 students only has a brother
9 - 7 = 2 students only have a sister
7 students have both brothers and sisters
probability of a student having a brother and a sister:
[tex]\frac{7}{28} = \frac{1}{4}[/tex]
In a class of 30 students, 6 have a brother and 12 have a sister. There are 14 students who do not have any siblings. What is the probability that a student chosen randomly from the class has a brother and a sister?
Answer:
32 siblings from the class theres a possibility that some students had more siblings and not everyone has one
Step-by-step explanation:
.
The probability that a student chosen randomly from the class has a brother and a sister is [tex]\frac{1}{15}[/tex].
What is probability?The chance that something will happen, or how likely it is that an event will occur.
Formula to calculate probabilityprobability of an event = [tex]\frac{number of favorable outcomes}{Total number of outcomes}[/tex]
According to the given question
we have total 30 students.
6 have a brother
12 have a sister
and 14 who don't have any siblings
If we se the provided Venn diagram
the number of students who have only sister is 10
and the number of student who have only brother is 4.
because, 6+12+14 = 32
but we have only 30 students
⇒ 2 students has a brother and a sister.
therefore,
the probability that a student chosen randomly from the class has a brother and a sister = [tex]\frac{number of students as a brother and a sister}{total number of students}[/tex]= [tex]\frac{2}{30}[/tex] =[tex]\frac{1}{15}[/tex]
Hence, the probability that the chosen student from the class has a brother and sister is [tex]\frac{1}{15}[/tex].
