Answer:
[tex]Red = 29[/tex]
Step-by-step explanation:
Given
[tex]Total = 60[/tex]
[tex]Purple = 11[/tex]
[tex]Green = 20[/tex]
Required
Number of red marbles, without counting
To do this, we simply subtract the sum of the purple and red marbled from the total marbles.
So, we have:
[tex]Red = Total - (Purple + Green)[/tex]
[tex]Red = 60 - (11 + 20)[/tex]
[tex]Red = 60 - 31[/tex]
[tex]Red = 29[/tex]

Step-by-step explanation:
The radius of any circle is the distance from the EXACT center, to any point of the circle.
The letters in the word STATISTICS are printed on identical index cards with one letter per card. The ten cards are
then placed in a hat, and one card is randomly chosen (without looking) from the hat. The random process we are
interested in is what letter is on the selected card.
(a) Make a table that shows the set of outcomes and the probability of each outcome.
Outcome
Probability
(b) Consider the following events:
V: the letter chosen is a vowel.
F: the letter chosen falls in the first half of the alphabet (that is, between A and M).
Determine the following probabilities:
P(V) =
P(F) =
P(FC
) =
P(V and F) =
P(V or F) =
(c) Are the events V and F mutually exclusive (disjoint)? Explain.
Answer:

someone please help!!!
Answer:
y = 3x + 5 option A
Step-by-step explanation:
For 2 lines that are parallel with slopes m1 and m2, the slopes are equal. Hence
m1 = m2
Given the line y = 3x - 5 Comparing with the general equation of a line
y = mx + c where m is the slope of the line
m = 3
hence m1 = m2 = m = 3
For the line that passes through the given point (2,11) Using
y - y1 = m (x - x1)
y - 11 = 3(x - 2)
y - 11 = 3x - 6
Add 11 to both sides
y = 3x - 6 + 11
y = 3x + 5

12 pounds of grapes cost $18.00
Step-by-step explanation:
The point, (12, 18) as plotted on the graph indicates that 12 pounds of grapes costs $18.
From the graph, we see that when x (pounds) = 12, y (cost) = 18.00.

One number added to twice another number is 30. The sum of the numbers is 19.
Write and solve a system of equations to represent this situation.
What is the value of the smaller number?
What is the value of the larger number?
I don't understand :(
Answer:
The smaller number is 8
The bigger number is 11
Step-by-step explanation:
let the first number be A
let the second number be B
A + 2B = 30..... equation 1
A + B = 19...... equation 2
Subtract equation 2 from 1.
A + 2B = 30
- A + B = 19
-------------------
0 + B = 11
B = 11
Substitute B = 11 into equation 2
A + B = 19
A + 11 = 19
collect like terms
A = 19-11
A = 8.
A= 8 and B = 11

Step-by-step explanation:
Two numbers have a sum of 527 and a difference of 195. What is the smaller of the two numbers?
Answer:
166
Step-by-step explanation:
let two numbers be x and y
according to question,
x+y=527..........equation 1
x-y=195...........equation 2
add both the equations you will get
x=361 and y= 166
So the smaller of two numbers is y=166

Are events A and C mutually exclusive
Answer:
They are mutually exclusive.
Step-by-step explanation:
A and B are mutually exclusive events if they cannot occur at the same time. This means that A and B do not share any outcomes and P(A AND B). Therefore, A and C are mutually exclusive
which formula should be used to find the area of the composite shape? A = 4(1/2Xbh) lw B. A=4bh+lw C. a=4bh+lw d. 2bh+bh The composite shape is a four pointed star.
Answer:
D. 2bh+bh
Step-by-step explanation:
You can divide that shape into five separate pieces, 4 triangles and 1 square.
The formula for the area of a triangle is A=1/2bh.
Multiply this by 4 becuase there are 4 triangles and you get A=2bh.
Then you add on the area of the square and you have A=2bh+bh

x P(x) 0 0.25 1 0.3 2 0.1 3 0.35 Find the standard deviation of this probability distribution. Give your answer to at least 2 decimal places
Answer:
The standard deviation of this probability distribution is 1.2.
Step-by-step explanation:
We have that:
P(X = 0) = 0.25
P(X = 1) = 0.3
P(X = 2) = 0.1
P(X = 3) = 0.35
Mean:
Each value multiplied by its probability. So
[tex]M = 0*0.25 + 1*0.3 + 2*0.1 + 3*0.35 = 1.55[/tex]
Variance:
Sum of the squares of the values subtracted from the mean, and multiplied by its probability.
[tex]V = 0.25*(0-1.55)^2 + 0.3*(1-1.55)^2 + 0.1*(2-1.55)^2 + 0.35*(3-1.55)^2 = 1.4475[/tex]
Standard deviation:
Square root of the variance. So
[tex]S = \sqrt{V} = \sqrt{1.4475} = 1.2[/tex]
The standard deviation of this probability distribution is 1.2.
