a bag holds 13 marbles. 6 are blue, 2 are green, and 5 are red. you select a marble from the bag. what is the probability that the marble you select is either blue or green
a. 5/26
b. 8/13
c. 5/13
d. 8/26
Answer:
[tex]\boxed {\boxed {\sf B. \ \frac{8}{13} }}[/tex]
Step-by-step explanation:
Probability is found by dividing the number of favorable outcomes by the total number of outcomes.
[tex]P= \frac{favorable \ outcomes}{total \ outcomes}[/tex]
For this problem, the favorable outcome is selecting a blue or green marble. There are 8 outcomes for this because there are 6 outcomes for blue and 2 fr green.
The total outcomes are all the marbles. Each marble could be an outcome, so there are 13 outcomes (1 for each marble).
[tex]P(blue \ or \ green) = \frac{8}{13}[/tex]
This fraction cannot be reduced, so the probability of selecting a blue or green marble is 8/13.

como simplifica essa expressão: 2*(x+5)+3*(5x+6):
Answer:
17 x + 28
Step-by-step explanation:
Simplify the following:
2 (x + 5) + 3 (5 x + 6)
Hint: | Distribute 2 over x + 5.
2 (x + 5) = 2 x + 10:
10 + 2 x + 3 (5 x + 6)
Hint: | Distribute 3 over 5 x + 6.
3 (5 x + 6) = 15 x + 18:
10 + 2 x + 18 + 15 x
Hint: | Group like terms in 10 + 2 x + 18 + 15 x.
Grouping like terms, 10 + 2 x + 18 + 15 x = (2 x + 15 x) + (10 + 18):
(2 x + 15 x) + (10 + 18)
Hint: | Add like terms in 2 x + 15 x.
2 x + 15 x = 17 x:
17 x + (10 + 18)
Hint: | Evaluate 10 + 18 using long addition.

Answer:
A. SinA=10/26 B. CosA=24/26 C. TanA=10/24 D. TanB=24/10
Step-by-step explanation:
You really need to remember this formula for trig: Soh Cah Toa
S=Sin O=Opposite H=Hypotenuse
C=Cosine A=Adjacent H= Hypot.
T=Tangent O= Oppo. A=Adjac.
Now if we take Soh, what it basically means is that the sine is equal to the opposite over the hypotenuse, same thing for the others, cosine is equal to the adjacent over the hypotenuse and tangent is equal to the opposite over adjacent. When you have a letter such as A or B in front of sin cos or tan, it represents which angle on the triangle does this imply to, if that makes sense. For example, for sin A you use Soh to find the ratio, opposite = 10 and hypotenuse = 26, so 10/26. Same thing for Cos A, adjacent = 24 and hypotenuse = 26. You apply the same thing for tan, but something happened, there is a TAN B, so what that means is that you go to angle B, and you apply the toa formula, opposite= 24 and adjacent = 10 so 24/10. Hope this answers your question. MAKE SURE YOU REDUCE YOUR RATIOS. :)

Which scatterplot shows a linear association?
Answer:
A scatter plot shows the association between two variables. A scatter plot matrix shows all pairwise scatter plots for many variables. If the variables tend to increase and decrease together, the association is positive. If one variable tends to increase as the other decreases, the association is negative.

The bear population in canada was 380,000 in the year 2015, and environmentalists think that the population is increasing at a rate of 2.5% per year
Answer:
The bear population after t years will be:
p(t) = 380,000*(1 + 0.025)^t
Step-by-step explanation:
Here the question is missing, so i will found an equation that can tell us the bear population as a function of the number of years that have passed since 2015, represented with the variable t.
The initial bear population in Canada was 380,000.
Each year the population increases by a 2.5%
Then after one year, the population is:
p(1) = 380,000 + 380,000*(2.5%/100%)
p(1) = 380,000 + 380,000*(0.025) = 380,000*(1 + 0.025)
After another year the population increases by 2.5% again, then the new population will be:
p(2) = 380,000*(1 + 0.025) + 380,000*(1 + 0.025)*(2.5%/100%)
p(2) = 380,000*(1 + 0.025) + 380,000*(1 + 0.025)*(0.025)
p(2) = 380,000*(1 + 0.025)*(1 + 0.025)
p(2) = 380,000*(1 + 0.025)^2
So we already can see the pattern here, the bear population after t years will be:
p(t) = 380,000*(1 + 0.025)^t
-6 x (1/3 + 1/3)What is the answer?
Answer:
−4
Step-by-step explanation
Answer:
−4
Step-by-step explanation:
-6 x (1/3 + 1/3)
Since 1/3 and 1/3 have the same denominator, add them by adding their numerators.
-6 x (1+1/3)
Add 1 and 1 to get 2.
-6 x (2/3)
Express -6 x (2/3) as a single fraction.
-6 x 2/3
Multiply −6 and 2 to get −12.
-12/3
Divide −12 by 3 to get −4.
−4
Determine whether each expression is equivalent to 100t^2-0.5t
Answer:
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{10^{t^{2}}}{100^{t}}[/tex].
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}}\cdot 2^{t^{2}}}{25^{0.5\cdot t}\cdot 4^{0.5\cdot t}}[/tex].
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}-0.5\cdot t}}{5^{t^{2}-0.5\cdot t}}[/tex].
Step-by-step explanation:
The expression to be evaluated is [tex]100^{t^{2}-0.5\cdot t}[/tex], we find by algebraic means the equivalent expression:
Possibility 1:
[tex]100^{t^{2}-0.5\cdot t}[/tex]
[tex]\frac{100^{t^{2}}}{100^{0.5\cdot t}}[/tex]
[tex]\frac{100^{t^{2}}}{(100^{0.5})^{t}}[/tex]
[tex]\frac{100^{t^{2}}}{10^{t}}[/tex]
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{10^{t^{2}}}{100^{t}}[/tex].
Possibility 2:
[tex]100^{t^{2}-0.5\cdot t}[/tex]
[tex]\frac{100^{t^{2}}}{100^{0.5\cdot t}}[/tex]
[tex]\frac{(50\cdot 2)^{t^{2}}}{(25\cdot 4)^{0.5\cdot t}}[/tex]
[tex]\frac{50^{t^{2}}\cdot 2^{t^{2}}}{25^{0.5\cdot t}\cdot 4^{0.5\cdot t}}[/tex]
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}}\cdot 2^{t^{2}}}{25^{0.5\cdot t}\cdot 4^{0.5\cdot t}}[/tex].
Possibility 3:
[tex]100^{t^{2}-0.5\cdot t}[/tex]
[tex]\left(\frac{500}{5} \right)^{t^{2}-0.5\cdot t}[/tex]
[tex]\frac{500^{t^{2}-0.5\cdot t}}{5^{t^{2}-0.5\cdot t}}[/tex]
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}-0.5\cdot t}}{5^{t^{2}-0.5\cdot t}}[/tex].
María tiene en su libreta de ahorros un capital de 123.000,si deposita el día lunes la cantidad de 12.670 .El día miércoles por una urgencia , realiza un giro de 56.000¿cual es el nuevo capital que posee? Escribe la operación utilizando números enteros
Answer:
$79.670.
Step-by-step explanation:
Dado que María tiene en su libreta de ahorros un capital de $ 123.000,si deposita el día lunes la cantidad de $12.670, y el día miércoles por una urgencia, realiza un giro de $56.000, para determinar cuál es el nuevo capital que posee se debe realizar el siguiente cálculo:
123.000 + 12.670 - 56.000 = X
135.670 - 56.000 = X
79.670 = X
Así, el nuevo capital que María posee en su cuenta es de $79.670.

Answer:
$1840.00
Step-by-step explanation:
The answer is 1840.00 because the formula for a trapezoid is A=a+b
divided by 2, then multiply by height, so, you did that on one half of the trapezoid, then the result, x2. After that, you multiply the result by 4 since each square foot of the carpet costs $4. Then, the result would be 1840.00.
Hope this helps! :)

How to round 8.6023 in the nearest tenth?
Answer:
8.6
Step-by-step explanation:
https://www.you.tube.com/watch?v=32gDF10ZXOA
( it might be wrong pls dont report me just let me kno y its wrong )
Answer:
8.6
Step-by-step explanation:
First of all consider the thousands in the decimal which is 2. Since 2 is not greater than 5 we have to remove the number 2 and 3 from the 8.6023.
We're left with 8.60. Now we see that there's a 0 in the hundredths so since it's not greater than 5 we remove it.
Now we're left with 8.6 which is to the nearest tenth.
