A jar contains 50 marbles, 21 are blue, 15 are yellow, and the rest are red. What is the probability that you pick out a blue marble?
Answer:
The probability of drawing a red marble = 2/5. The probability of drawing a blue marble is now = 1/4. The probability of drawing a red marble = 2/5.
Step-by-step explanation:
Answer:
42%
Step-by-step explanation:
There are 21 blue marbles out of the 50. Divide 21 with 50:
21/50 = 0.42
Next, change the decimal to a percentage. To do so, move the decimal point to the right two place values and slap a percentage sign onto it:
0.42 = 42%
42% is your probability of picking a blue marble.

Answer:
10 unit³
Step-by-step explanation:
Volume of the rectangular cube:
Area × lenght
Given ;
Area = 25/4 unit²
Length = 8/5 unit
Volume = Area × length
= 25/4 × 8/5
= (5 × 2) = 10 unit³
Solve the following inequality in two ways and make a claim as to which
method is more efficient.
1/4 (8n - 12) < n + 2
Answer:
The solution of the given inequality n < 5
Step-by-step explanation:
Explanation:-
Given inequality
[tex]\frac{1}{4} (8 n -12 ) < n +2[/tex]
Step(i):-
Cross multiplication '4' we get
8 n - 12 < 4 ( n +2)
8 n - 12 < 4 n + 4×2
8 n - 12 < 4 n +8
Subtracting '4 n ' on both sides, we get
8 n - 4 n - 12 < 4 n - 4 n +8
4 n - 12 < 8
Step(ii):-
Adding ' 12 ' on both sides , we get
4 n -12 + 12 < 8 + 12
4 n < 20
Dividing "4' on both sides , we get
n < 5
The solution is n < 5
Conclusion:-
The solution of the given inequality n < 5

Answer:
Step-by-step explanation:
In the first case the function could become undefined as x approaches -3 or 3 from either direction. The vertical asymptotes are x = -3 and x = +3.
In the second case, there's only one vertical asymptote, because the denominator can be zero (0) only at x = 0.

Which equation in point-slope form contains the point (-2, -6) and has slope -4?
y - 2 = -4(X-6)
y + 2 = -4(x + 6)
.
y + 6 = -4(x + 2)
y-6 = -4(x - 2)
Answer:
Step-by-step explanation:
y + 6 = -4(x + 2) is the point-slope form
y + 6 = -4x - 8

For the data set 6, 5, 10, 11, 13, the mean, X, is 9. What is the standard
deviation?
Answer:
standard deviation = 3.0331
Step-by-step explanation:
You can solve for this two different ways.
If you have a TI-84 calculator or something similar, type all the data into list 1. Then click the stat button, then the calc button, then 1-vars stats. This will give you mean, standard deviation, median, mode, etc.
If you are solving by hand, find the different between each data point and the mean. Square these numbers and find the average. Then take the square root of that.
3^2 + 4^2 + 1^2 + 2^2 + 4^2 = 46
46/5 = 9.2
square root of 9.2 = 3.0331

Which of the following best describes the equation below? y = 5x - 15
a.neither linear or non linear
b.non linear
c.both linear and non linear
d.linear
Answer:
D linear
Step-by-step explanation:
We can tell pretty easily that this is a linear equation. How? Look at the highest degree of x!
This means the highest exponent of x. It looks like we have 5x, which you can think of as 5x to the first power. Whenever the highest exponent is 1, the equation is linear.

Fill in the missing value:
A.) 17
B.) 168
C.) 13
D.) 7
Answer:
13
Step-by-step explanation:
Use the pythagorean theorem where 12 squared plus 5 squared is the square of the hypotenuse. 12 squared is 144 and 5 squared is 25. 144+25=169. Taking the square root of 169 we get 13. Therefore the missing side is 13 units long.

Write a recursive formula for the following arithmetic sequence.
8, 5, 2, −1,
Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 3
Step-by-step explanation:
A recursive formula allows a term in the sequence to be found from the previous term by adding the common difference to it.
Here d = 5 - 8 = - 3, thus
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] - 3 with a₁ = 8 ← recursive formula

squared.
Find the missing side.
Answer:
x = 10 units
Step-by-step explanation:
The formula for the area of a triangle of base x and height h is A = (1/2)(x)(h).
Here A = (1/2)(x)(8) = 40, so 8x = 80 and x = 10 units
If we look at this triangle we can see the straight line (the height). We want to use the height to figure out the side? Well divide 40 with the height (8). And now you get 5(cause 5*8 is 40. duh)
