Answer:
2x+6y-4
Step-by-step explanation:
First distribute x and 3y
2 times x is 2x
2 times 3 is 6y
(2x+6y) -4
2x+6y-4

What is the length of the dotted line in the diagram below? Round to the nearest tenth.
Answer:
length of dotted diagonal line = 11
Step-by-step explanation:
Using the Pythagorean theorem:
length of rectangle² = 9² + 6² = 81 + 36 = 117
length of rectangle = √117 = 10.82
length of diagonal² = 2² + 10.82² = 4 + 117 = 121
length of diagonal = 11

When n=343 college students are randomly selected and surveyed, it is found that x=110 own a car. Find a 99% confidence interval (CI) and margin of error (ME) for the true proportion of all college students who own a car.
Answer:
The margin of error will be "0.65". A further explanation is provided below.
Step-by-step explanation:
The given values are:
n = 343
x = 110
At 99% confidence level,
[tex]\alpha = 1-99[/tex]%
[tex]=1-0.99[/tex]
[tex]=0.01[/tex]
then,
[tex]\frac{\alpha}{2} =\frac{0.01}{2}[/tex]
[tex]=0.005[/tex]
or,
[tex]Z_{\frac{\alpha}{2} }=Z_{0.005}[/tex]
[tex]=2.576[/tex]
Now,
The point estimate will be:
⇒ [tex]\hat{P}=\frac{x}{n}[/tex]
⇒ [tex]=\frac{110}{343}[/tex]
⇒ [tex]=0.321[/tex]
or,
⇒ [tex]1-\hat{P}=1-0.321[/tex]
⇒ [tex]=0.679[/tex]
The margin of error will be:
⇒ [tex]E=Z_{\frac{\alpha}{2} }\times \sqrt (\frac{(\hat{P}\times (1 - \hat{P})) }{n} )[/tex]
On substituting the above values, we get
⇒ [tex]=2.576\times \sqrt{\frac{0.321\times 0.679}{343} }[/tex]
⇒ [tex]=2.576\times \sqrt{\frac{0.217959}{343} }[/tex]
⇒ [tex]=0.065[/tex]
hence,
⇒ [tex]\hat{P}-E<p<\hat{P}+E[/tex]
⇒ [tex]0.321-0.065<p<0.321+0.065[/tex]
⇒ [tex]0.256,0.386[/tex]

Step-by-step explanation:
All dimensions of a cylinder are multiplied by 1.5. Which statement is true?
A. The total surface area is multiplied by 3.375.
The volume is multiplied by 2.25.
B. The total surface area is multiplied by 2.25.
The volume is multiplied by 3.375.
C. The total surface area is multiplied by 3.
The volume is multiplied by 4.5.
D. The total surface area is multiplied by 4.5.
The volume is multiplied by 3.
Answer:
The true statement is;
B. The total surface area is multiplied by 2.25
The volume is multiplied by 3.375
Step-by-step explanation:
By scale drawing proportionality, we have;
The amount by which all the dimensions of the cylinder are multiplied to create an image of the cylinder = 1.5
∴ The scale factor between the original cylinder and the image of the cylinder, S.F. = 1.5
By rule, we have;
The area factor of the surface area = S.F.² = 1.5² = 2.25
Therefore;
The total surface area of the original cylinder is multiplied by 2.25 to get the total surface area of the image of the cylinder
By rule, we have;
The volume factor = S.F.³ = 1.5³ = 3.375
Therefore;
The volume of the original cylinder is multiplied by 3.375 to find the volume of the image of the cylinder.

Answer:
each apple is £ 1.80
Step-by-step explanation:
i first multiplied the cost for one pear by 7, to get how much money was spent on pears out of the 12.70.
Then i took the remaining money and divided it by 2 to get how much each apple costs.
Answer:
1.80
Step-by-step explanation:
1) Price of Pears
[tex]1.30 * 7 = 9.10[/tex] formating: 1.30*7 = 9.10
2) Price of Apples
[tex]12.70 - 9.10 = 3.60[/tex] formating: 12.70-9.10 = 3.60
3) Price of Apples/Kg
[tex]\frac{3.60}{2} = 1.80[/tex] formating: 3.60/2 = 1.80

Write the equation in point-slope form of the line that passes through the given point and has the given slope: (-2, -1); m=-3
Answer:
y+1=-3(x+2)
Step-by-step explanation:
point-slope form is the formula y-y1=m(x-x1), where (x1, y1) is a point and m is the slope
we are given a point (-2, -1) and a slope of -3
all we really need to do is substitute the given into the formula
remember: since the formula gives subtraction, we're going to be subtracting, even though we have negative numbers
substitute -2 as x, -1 as y and -3 as m
y--1=-3(x--2)
we can simplify this equation:
y+1=-3(x+2)

An arborist examined trees in an orchard to see if they were infected with a virus. The arborist counted 7 infected trees and 43 healthy trees. What percentage of the trees in the orchard were infected?
Answer: Percentage of infected trees =2%
Step-by-step explanation:
Number of Infected trees =7
Number of healthy trees=43
Total number of trees in the orchard=43+7=50
Percentage of infected trees =Number of Infected trees/Total number of tress in the orchard x 100
7/50 x 100 =2%

9514 1404 393
Answer:
A. 10 units
Step-by-step explanation:
The y-intercept of f(x) is f(0) = -9.
The y-intercept of g(x) is g(0) = g(1)/2 = 1.
The distance between these points is ...
1 -(-9) = 10 . . . units
__
We notice that the common ratio of the table values of g(x) is 4/2=2, so the value for x=0 will be a factor of 2 less than the value for x=1.
