There are 6 green marbles and 7 blue marbles in a bag. You randomly choose one of the marbles. What is the probability of choosing a green marble? Write your answer as a fraction in simplest form.
Answer: 6/13
Step-by-step explanation:
Theres 13 marbles in total (6+7)
Theres only 6 green marbles
so 6/13
Answer:
7/13
Step-by-step explanation:
first you count how many marbles are in the bag (green plus blue) and then you divide green marbles with total marbles in the bag

AXYZ has vertices at (0.0), (6,9), and (15.0).
Y (6,9)
X (0, 0)
Z (15, 0)
AXYZ is dilated by a scale factor of
about the origin.
What are the coordinates of the vertices of the image?
OA (0,0).(2,3), (5.0)
OD. (0,0).(8,12).(20,0)
OR ( }).2.3), (55)
OE ( ).(8,12), (20,3)
Oc (0.01.(4.0) (10,0)
Answer:
The coordinates of the vertices of the image are (0, 0), (2, 3), (5, 0) ⇒ (A)
Step-by-step explanation:
Let us talk about dilation
A dilation is a transformation that changes the size of a figure. It can become larger or smaller, but the shape of the figure does not change.The scale factor measures how much larger or smaller the image will beIf the scale factor greater than 1, then the image will be largerIf the scale factor between 0 and 1, then the image will be smaller→ If point (x, y) dilated with scale factor m about the origin, then
→ Its image is (m x, m y)
Let us solve the question
∵ ΔXYZ has vertices:
→ X = (0, 0)
→ Y = (6, 9)
→ Z = (15, 0)
∵ ΔXYZ is dilated by a scale factor 1/3 about the origin
→ Multiply each coordinate in each vertex by the scale factor 1/3
∵ (0 × [tex]\frac{1}{3}[/tex] , 0 × [tex]\frac{1}{3}[/tex] )
∴ X' = (0, 0)
∵ (6 × [tex]\frac{1}{3}[/tex] , 9 × [tex]\frac{1}{3}[/tex] )
∴ Y' = (2 , 3)
∵ (15 × [tex]\frac{1}{3}[/tex] , 0 × [tex]\frac{1}{3}[/tex] )
∴ Z' = (5, 0)
∴ The coordinates of the vertices of the image are (0, 0), (2, 3), (5, 0)

Sometimes it is easier to compare values when they all have the same number of decimal places.
Write 1.64 as a mixed number in lowest terms.
Answer:
[tex]1\frac{16}{25}[/tex]
Step-by-step explanation:
So we have the decimal:
[tex]1.64[/tex]
We can rewrite this as:
[tex]=1+0.64[/tex]
0.64 is the same as 64/100. So:
[tex]=1+\frac{64}{100}[/tex]
We can divide both layers by 4. This gives us:
[tex]=1+\frac{64/4}{100/4}[/tex]
Divide:
[tex]=1+\frac{16}{25}[/tex]
So, as a mixed fraction, this is:
[tex]1\frac{16}{25}[/tex]
And we're done!
Answer:
1 16/25
Step-by-step explanation:
You write 1.64 as 1 64/100
Then you simplify it to 1 16/25

Step-by-step explanation:Because a positive cancels the negative so it leaves them with a positive
Answer:
Subtracting a negative number from a positive number—when you see the subtraction (minus) sign followed by a negative sign, turn the two signs into a plus sign. Thus, instead of subtracting a negative, you're adding a positive, so you have a simple addition problem.

formula of the straight line parallel to y axis
Step-by-step explanation:
To get a straight line parallel to the y-axis you need to use the formula x= the number that x is equal to in the coordinate where it cuts the x-axis. Since you didn't specify the coordinate where your parallel cuts the x-axis I cant determine the actual number. Where your parallel cuts the x-axis you will get the coordinate (x,0). The number that is written instead of the x is the number you should use in the formula x=? instead of the '?'. I hope this wasn't too confusing.

Answer:
Step-by-step explanation:
Given the following :
Initial Position or depth of leatherback sea turtle = 850m below sea level
He went up 165m and then descended 165m
A.) change in position of the sea turtle from the depth where it was swimming :
B.) Integer to represent tbee sea turtle's change in position :
Change in position : [Distance moved in the upward direction (ascending) - distance moved downward (descending)]

write the expression in radical form. 2 4/5
Answer:
[tex]\sqrt[5]{2^4}[/tex]
Step-by-step explanation:
Maybe you want 2^(4/5) in radical form.
The denominator of the fractional power is the index of the root. Either the inside or the outside can be raised to the power of the numerator.
[tex]2^{\frac{4}{5}}=\boxed{\sqrt[5]{2^4}=(\sqrt[5]{2})^4}[/tex]

In many cases, it is preferred to keep the power inside the radical symbol.
What is an equation of the line that passes through the point (-1,4) and is parallel
to the line x + y = 4?
Answer:
y = -x + 3
Step-by-step explanation:
Solve x + y = 4 for y
You'll get y= -x+4
The parallel line has the same slope so use this in the point given to find the y intercept. y = -x +3

Which expression us equivalent to this polynomial expression?
(2a - 3b) (2a^2 + 6b^2) + ( 6a^2b + 12ab^2 - 7b^3)
Answer:
D. 4a³ + 24ab² - 25b³
Step-by-step explanation:
Simplify the given polynomial expression to find its equivalent as follows:
(2a - 3b)(2a² + 6b²) + (6a²b + 12ab² - 7b³)
2a(2a² + 6b²) -3b(2a² + 6b²) + (6a²b + 12ab² - 7b³)
4a³ + 12ab² - 6a²b - 18b³ + 6a²b + 12ab² - 7b³
Collect like terms
4a³ - 6a²b + 6a²b + 12ab² + 12ab² - 18b³ - 7b³
4a³ + 24ab² - 25b³
Therefore, 4a³ + 24ab² - 25b³ is equivalent to the polynomial expression, (2a - 3b)(2a² + 6b²) + (6a²b + 12ab² - 7b³).
Answer:A- 4a³+24ab²-25b³

The ratio of lions to giraffes living in the grasslands was 13 to 2. If there
were 52 lions, how many giraffes lived in the grasslands?
Answer:
8 giraffes
Step-by-step explanation:
52/13 = 4
4 x 2 = 8
Answer:
8 giraffes
Step-by-step explanation:
You can make ratios like this:
13/2=52/?
There is something called the butterfly method where you would multiply the numbers that are diagonal (i.e. 2*52), and divide by what number is left (104/13), and that would give you the answer of the missing number (8).

Country Financial, a financial services company, uses surveys of adults age and older to determine if personal financial fitness is changing over time (USA Today, April 4, 2012). In February of 2012, a sample of adults showed indicating that their financial security was more than fair. In February of 2010, a sample of adults showed indicating that their financial security was more than fair. What is the p value
Complete question is;
Country Financial, a financial services company, uses surveys of adults age 18 and older to determine if personal financial fitness is changing over time (USA Today, April 4, 2012). In February of 2012, a sample of 1000 adults showed 410 indicating that their financial security was more than fair. In February of 2010, a sample of 900 adults showed 315 indicating that their financial security was more than fair. What is the p value?
Answer:
p-value = 0.006934
Step-by-step explanation:
First of let's define the hypotheses.
Null hypothesis: H0: p1 - p2 = 0
Alternative hypothesis: Ha: p1 - p2 ≠ 0
We are given;
Number of people in 2012 that indicated their financial security was more than fair; x1 = 410
Number of people in 2010 that indicated their financial security was more than fair; x2 = 315
Sample in 2012; n1 = 1000
Sample in 2010; n2 = 900
proportion of people in 2012 that indicated their financial security was more than fair; p1 = x1/n1 = 410/1000 = 0.41
proportion of people in 2010 that indicated their financial security was more than fair; p2 = x2/n2 = 315/900 = 0.35
Now, let's find the z - score with the formula;
z = (p1 - p2)/√[(p1(1 - p1) × (1/n1)) + (p2(1 - p2) × (1/n2))]
Thus;
z = (0.410 - 0.35)/√[(0.41(1 - 0.41) × (1/1000)) + (0.35(1 - 0.35) × (1/900))]
z = 0.06/√0.00049467778
z ≈ 2.7
From online p-value calculator attached using z-value = 2.7; two tailed distribution; significance level = 0.05;
We have; p-value = 0.006934
