Paul will roll two standard dice simultaneously. If Event A = both dice are odd and Event B = at least one die is even, which of the following best describes events A and B?
Answer:
Mutually Exclusive
Dependent
Step-by-step explanation:
Given that both events cannot occur at the same time, that is "both dice cannot be odd (event A) if at least one of the dice is even (event B).
Hence, this is MUTUALLY EXCLUSIVE.
Also, given the fact that the occurrence of one event (event A) affects the probability of the other (event B).
Hence, this is DEPENDENT.

Given:
The limit problem is:
[tex]\lim_{x\to 3}(x^2+8x-2)[/tex]
To find:
The limit of the function by using direct substitution.
Solution:
We have,
[tex]\lim_{x\to 3}(x^2+8x-2)[/tex]
Applying limit, we get
[tex]\lim_{x\to 3}(x^2+8x-2)=(3)^2+8(3)-2[/tex]
[tex]\lim_{x\to 3}(x^2+8x-2)=9+24-2[/tex]
[tex]\lim_{x\to 3}(x^2+8x-2)=33-2[/tex]

find each missing length. give all answers in the simplest radical form.
Answer:
45°
Step-by-step explanation:
the sum of angles in a triangle is equal 180°
we have been given that one angle equals yo 90° and the other equals to 45°
let "?" be the unknown angle
====> 180° = 90° + 45° +?
? = 180° - (90° + 45°)
? = 180° - 135°
? = 45°

A decimal number is a very common number that we use frequently.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
As per the given expression,
2[tex]\sqrt[4]{x^{7}}[/tex]
Open the radical sign of the above,
2[tex]\sqrt[4]{x^{7}}[/tex] = 2[tex]x^{7/4}[/tex]
Since 7 and 4 are both integers thus they will be rational exponents.

3RD TIME PLS REALLY NEED THIS
Answer:
Part A: a) Corresponding angles
Part B: b) 12x - 10 = 10x + 8
Part C: x = 9
m<1 = 98
m<2 = 82
Explanation:
B)
Since they're corresponding angles, they're equal to each other:
12x - 10 = 10x + 8
C)
12x - 10 = 10x + 8
2x = 18
x = 9
m<1:
12(9) - 10 = 98
m<2:
98 + y = 180
y = 82
9514 1404 393
Answer:
A. a
B. b
C. 9, 98, 82
Step-by-step explanation:
See attached.
"Corresponding" angles are those in the same direction from the point of intersection. Here, angles 1 and 3 are both northwest of the intersection point, so are corresponding.
From ...
12x -10 = 10x +8
2x = 18 . . . . . . . . . . . add 10-10x to both sides of the equation
x = 9 . . . . . . . divide by 2
Angles 1 and 3 are the same measure, so we choose the easier expression to evaluate mentally. Multiplying by 10 is easier than by 12, so we use 10·9+8=98 as the measure of angles 1 and 3. Angle 2 is the supplement of this.

Alex's driveway is 27 yards long and 10 yards wide.how many feet long is the driveway
Answer:
81 feet
Step-by-step explanation:
3 feet = 1 yard
Answer:
81 feet wide
Step-by-step explanation:
1) The 10 yards wide is not necessary since we only need length.
2) There are 3 feet in a yard.
3) 27 yards multiplied by 3 feet equals = 81 feet.
4) 27 * 3 = 81 feet

Here, [tex]x[/tex] represents temperature and [tex]y[/tex] denotes rate of chirping per minute.
Step-by-step explanation:
Let [tex]x[/tex] represents temperature and [tex]y[/tex] denotes rate of chirping per minute.
At [tex]106[/tex]°F, a certain insect chirps at a rate of [tex]67[/tex] times per minute.

Answer:
(4,18)
Step-by-step explanation:
Answer:
(4,18)
Step-by-step explanation:
We can just pluck the x values into the equation: y = 5x -1 to see if the y values fit.
1. y = 5(4) - 1
= 20 - 1
= 19 (Nope, 18 is not 19)
2. y = 5(3) - 1
= 15 - 1
= 14 (Yep, same as option)
3. y = 5(0) - 1
= 0-1
= -1 (Yep, same as option)
4. y = 5(2) - 1
= 10 - 1
= 9 (Yep, same as option)
A ticket to the state fair cost $15. The equation y=15x relates the total cost of tickets (y) to the number of tickets purchased (x). Identify the unit rate in the equation.
Answer:
15
.
Step-by-step explanation:
Ticket cost = $15
Cost equation :
y = 15x
x = number of tickets purchased
y = total cost of x tickets
The unit rate in the equation is the Coefficient of x ; which is the sales price of one ticket.
Hence, the unit rate is $15

Answer:
x = 11 units
Step-by-step explanation:
Area of triangle = (base + base 2) * h *1/2
so (7 + x )* 7 * 1/2 = 63
63 x 2 = 126
126 / 7 = 18
18-7 = x
x = 11
Check
(7+11)* 7 * 1/2
18* 7 = 126
126 x 0.5 = 63

1) It takes Elisa six hours to pick forty bushels of apples. Kim can pick the san amount in ten hours. Find how long it would take them if they worked together
Step-by-step explanation:
Elsa 40÷6= 6.666, or 6 2/3 bushels per hour
Kim 40÷10= 4 bushels per hour.
together, they pick 10.66 bushels per hour, so 40÷ 10.66= 3.75 hours, or 3 hours, 45 minutes

Answer:
Step-by-step explanation:
(+5) + (+2) = +7
If both numbers have same sign, add and the result will have the common sign
v) (-5) + (-2) = (-7)
Both numbers have 'negative sign'. So, add and the result will have the 'negative sign'
Viii) (+6) + (-3) = +3
Both numbers have different sign. So, subtract and the result will have the sign of the bigger number. Here the bigger number is '6' and its sign is 'positive'. so, the result will have positive sign
xi) (-4) + (+8) = +4
Both numbers have different sign. So, subtract and the result will have the sign of the bigger number. Here the bigger number is '8' and its sign is 'positive'. so, the result will have positive sign
