Step-by-step explanation:
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:
I think the answer is c I guess

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

Order the cars based on how far they drive on 1 gallon of gas. Place the car that travels
farthest on top.
0.2 gallons used for 7 miles
0.5 gallons used for 12 miles
0.9 gallons used for 25 miles
Step-by-step explanation:
First car.
0.2 gallons used for 7 miles.
Distance drive on 1 gallon of gas [tex]=\dfrac{7}{0.2}=35\ \text{miles}[/tex]
Second car.
0.5 gallons used for 12 miles.
Distance drive on 1 gallon of gas [tex]=\dfrac{12}{0.5}=24\ \text{miles}[/tex]
Third car.
0.9 gallons used for 25 miles.
Distance drive on 1 gallon of gas [tex]=\dfrac{25}{0.9}=27.8\ \text{miles}[/tex]
So, the first car traveled fast while the second car traveled least. Hence, the sequence is first car > third car > second car.
PLEASE HELP ASAP IM PANICKING :(((

Which of the following is true of a radius of a circle?
(1) Radius is twice the diameter in any circle
(2) Radius is the distance from the center to any point on the circle.
(3) All radii in circles have the same value.
The second one is correct (Radius is the distance from the center to any point on the circle)
Answer:
2.)
Step-by-step explanation:
The radius of any circle is the distance from the EXACT center, to any point of the circle.
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

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

x multiplied by seven = 7x
eighteen subtracted from product (7x) = -18
7x - 18
Answer:
7x-18
Step-by-step explanation:
the ans is 7x-18 because x is multiplied to 7 so its 7x

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

distance of -2,-6 and 4,2
Step-by-step explanation:
distance = -6-(-2) and 4-2
-6+2 and 2
-4 and 2 is distance
Answer:
[tex]d = \sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }[/tex]
d = √(4 - (-2))² + (2 - (-6))²
d = √36 + 64
d = 10
A convenience store sells a coffee mug that comes
with a special price for refills using the mug. The
equation C = 2.3r + 6.5 represents the cost C, in
dollars, of the mug and r refills. What is the cost of
the mug?
Answer:
The cost of the mug is of $6.50.
Step-by-step explanation:
The cost of the mug and r refills is given by the following equation:
[tex]C(r) = 2.3r + 6.5[/tex]
Cost of the mug:
The cost of the mug is found when no refills are bought, that is, C when [tex]r = 0[/tex], which is [tex]C(0)[/tex]
[tex]C(0) = 2.3*0 + 6.5 = 6.5[/tex]
The cost of the mug is of $6.50.

Laci is filling a circular kiddie play pit with balls. The play pit has a radius of 7ft and each bag of balls covers 15 square feet. How many bags would she need to buy to have enough to cover the play pit
Answer:
10.26 bags
Step-by-step explanation:
Area of circle :
A = πr²
radius, r = 7ft
A = π * 7²
A = π * 49
A = 153.93804 ft²
Since a bag covers 15 ft² ;
Number of bags needed will be :
Area / number of square feet per bag
153.93804 ft² / 15 ft²
= 10.262536 bags
= 10.26 bags
Answer:
10.21
this is the correct answer because 10.21 is right

What are you to find?
Step-by-step explanation:
Please state in your question and I will help you solve it. Thanks for your cooperation.
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
