You roll two number cubes.
Let event A = You roll an even number on the first cube.
Let event B = You roll a 4 on the second cube.
Are the events independent or dependent? Why?
A. Independent, because the outcome of the first roll doesn't affect
the outcome of the second roll.
B. Independent, because they have no outcomes in common.
C. Dependent, because both cubes have six sides.
D. Dependent, because 4 is an even number.
Answer:
D
Step-by-step explanation:
They are both even numbers the 4 is seperated into 2,2 and if 4 is an even and event A is even it would be dependent

51.6
38
N
Answer:
[tex]NO= 31.2[/tex]
Step-by-step explanation:
See attachment for triangle
From the attachment, we have:
[tex]KL = 51.6[/tex]
[tex]LM= 38[/tex]
[tex]OP = 23[/tex]
Required
Find NO
This will be calculated using the following equivalent ratios:
[tex]NO : OP = KL : LM[/tex]
This gives:
[tex]NO : 23= 51.6: 38[/tex]
Express as fraction
[tex]\frac{NO }{ 23}= \frac{51.6}{ 38}[/tex]
Make NO the subject
[tex]NO= \frac{51.6}{ 38} * 23[/tex]
[tex]NO= \frac{51.6* 23}{ 38}[/tex]
[tex]NO= \frac{1186.8}{ 38}[/tex]
[tex]NO= 31.2[/tex] --- approximated

I need help plz 6x-5=2x+7
Answer: x=3
Step-by-step explanation; Add 5 to both sides of the equation
6x-5+5=2x+7+5
simplify: add the numbers
6x-5+5=2x+75 = 6x=2x + 7+5
6x =2x + 7+5
6x=2x +12.
subtract 2x from both ides of the equation: 6x=2x + 12
6x - 2x =2x + 12-2x6
combine like terms u should get 4x= 12
divided both sides of the equation by the same term 4x=12 4x/4 =12/4
Cancel terms that are in both the numerator and denominator u should get x=12/4
divided the numbers and ur answer is X=3

(a) An angle measures 51°. What is the measure of its supplement?
(b) An angle measures 27°. What is the measure of its complement?
Answer:
a - 129
b - 63
Step-by-step explanation:
for a - supplementary angles add up to equal 180
so to find the measure of its supplement we subtract the given angle from 180 180-51=129
so the measure of a supplement angle is 129
for b - complementary angle add up to equal 90
so to finds the measure of its complement we subtract the given angle from 90
90-27=63
so the measure of its complement is 63
Answer:
(a) An angle measures 51°. the measure of its supplement=180-51=129°
b) An angle measures 27°. the measure of its complement=90-27=63°

Answer:
(x, y) → (-∞, -∞), (+∞, +∞)
Step-by-step explanation:
The expression is of odd degree with a positive leading coefficient. It will have a generally upward slope (/). That is, the sign of f(x) will match the sign of x for large-magnitude values of x:
x → -∞, f(x) → -∞
x → ∞, f(x) → ∞

Spencer is correct
Step-by-step explanation:
because you always go for the lowest number
Answer:
Spencer
Step-by-step explanation:
Spencer got it corret because the answer is x=2/5
but jeremiah subtracted 6x so he got x=1/3

A software engineer creates a LAN game where an 8 digit code made up of 1,2,3,4,5,6,7,8 has to be decided on, universal code . There is a condition that each number has to be used a and no number can be repeated . What is the probability that first 4 digits of the code are even numbers ?
Answer:
0.0143 = 1.43% probability that first 4 digits of the code are even numbers.
Step-by-step explanation:
Arrangements of n elements:
The number of possible arrangements of n elements is given by:
[tex]A_{n} = n![/tex]
Probability:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Desired outcomes:
First four digits are even(2, 4, 6 and 8 are even, so arrangements of 4 elements).
Last four digits are odd(1, 3, 5 and 7 are odd, so the last four elements are also arrangements of 4 elements). So
[tex]D = 4!*4! = 24*24 = 576[/tex]
Total outcomes:
Arrangements of 8 digits. So
[tex]T = A_{8} = 8! = 40320[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{576}{40320} = 0.0143[/tex]
0.0143 = 1.43% probability that first 4 digits of the code are even numbers.
What is the total deposit on the deposit slip below?
Michelle deposited $3,400 into an account. She made no additional withdrawals or deposits. Michelle earned 1.95% annual simple
interest on the money in the account
What was the balance in her account at the end of 2.5 years?
Enter the amount in the account in the box.
$_______
Answer: 96 cents or 0.96
Step-by-step explanation:
When in a money problem like this and it is telling you to find the tax, fee, or and bonus you move the decimal in front of the number or decimal and round to the nearest penny and in this situation .195 rounds to .96
The balance in her account at the end of 2.5 year should be considered as the $3,568.
Calculation of the balance in the amount:Since deposited amount si $3,400
The interest rate is 1.95%
And, the time period is 2.5 years
So, here the balance should be like
[tex]= 3400 \times (1 + 1.95\%)^{2.5[/tex]
= $3,568
hence, The balance in her account at the end of 2.5 year should be considered as the $3,568.

A soft-drink machine is regulated so that the amount of drink dispensed is approximately normally distributed with known standard deviation, sigma. Given a random sample of n drinks and the sample mean, x-bar, you find a 90% confidence interval for the mean of all drinks dispensed by this machine. Then you calculate a 90% confidence interval (same confidence level) using a larger sample, for example (n 20) drinks. Also, you notice that the sample mean, x-bar, is the same for both samples.
Required:
Was this a reasonable decision?
Answer:
This is a reasonable decision because the sample size has no effect on the 90% confidence interval
Step-by-step explanation:
90% confidence interval
larger sample size = 20
condition : sample mean ( x-bar ) is the same for both samples
This is a reasonable decision because the sample size has no effect on the 90% confidence interval
from condition 1 :
Amount of drink dispensed is normally distributed with known standard deviation , given a random sample of n drinks and the sample mean at a confidence interval of 90%
for condition 2 :
sample size = 20
mean = 2.25 ( assumed value )
std = 0.15 ( assumed value )
Z = 1.645 ( Z-value )
determine the 90% confidence interval
= mean ± z [tex]\frac{std}{\sqrt{n} }[/tex]
= 2.25 ± 1.645 [tex]\frac{0.15}{\sqrt{20} }[/tex]
= 2.25 ± 0.0335 = ( 2.2835 , 2.2165 )

r = 5 cm
5 cm
LSA= [ ? ]n cm?
Leave your answer in terms of T.
Enter the number that goes in the green box.
Answer:
50π cm²
Step-by-step explanation:
Lateral surface area of a cylinder is the area surrounding curved surface of the cylinder
Thus:
Lateral surface area of the cylinder = 2πrh
Where,
r = 5 cm
h = 5 cm
Plug in the values
Lateral Surface Area = 2*π*5*5
= 50π cm²

Describe how you calculated surface area. Provide a few examples of how the concept of surface area can be used in the real world!!
Answer:
Halo!!! i wrote my answer below your epic btw
Step-by-step explanation:
you first have to break up the surface of the shape into smaller shapes so that they are easier to work with. you then calculate all of the shapes and add them together. this can be used in the real world to find the area of houses when you need to find how much space an area of the house has.
PS:If u didnt learn to find surface area this way insert anything you want into the beggining sorry i dont know what youve been learning
