Answer:
11
Step-by-step explanation:
A whole number is an integer greater than 0.
-76 , -34 , -57 are all negative so they are not whole numbers.
0 is too small so it also is not a whole number.
By ruling out those numbers you are left with 11 which is positive and greater than 0. Therefore, the correct answer is 11.
Answer:
0 and 11
Step-by-step explanation:
Whole numbers are set yo to be real numbers that include zero and all positive numbers while it excludes fractions, negative integers and decimals.
Therefore, from our question, 0 and 11 are whole numbers while -76, -34 and -57 are excluded because they are negative integers.
Find the value of x for which r || s. Then find m∠1 and in∠2.
m∠1=75-2x
mZ291-3x
The value of x for which r || s is
mt=1
m<2=□
Answer:
Since r and s are parallel lines, angle 1 = angle 2 (corresponding angles)
75 - 2x = 91 - 3x
x = 16
Angle 1 = 75 - 2(16) = 43°
Angle 2 = Angle 1 = 43°

Samuel was absent for the last biology test. For those who took the test, the mean was 84.6, the median was 82, and the mode was 88. When Samuel took the test, the class mean went down to exactly 84. His score was different from every other students’ score. What effect, if any, did Samuel’s score have on the class mode?
A: None; the mode stayed the same.
B: It decreased the mode by exactly 1 point.
C: It increased the mode by exactly 1 point.
D: It increased the mode by greater than 1 point.
E: The effect of Samuel’s score on the mode cannot be determined from the given information.
The correct option is A: None; the mode stayed the same.
What is Mode?Mode of a data set is the value that occur most frequently in a data set.
There may be no mode, one mode or more than one mode for a data depending on the number of times values are repeating.
Given that before Samuel taking a test,
Mean = 84.6
Median = 82
Mode = 88
After Samuel took the test,
Mean = 84
Also given that, his score was different from every other students’ score.
This means that from the data of scores, Samuel's score is not repeating.
Mode is the most repeating element.
So Samuel's score does not effect the mode and thus stayed the same.
Hence the mode stayed the same.

The inverse of the conditional statement is : if two lines do not intersect, then the lines are not coplanar.
Conditionals are commands used in programming languages to handle decisions.
Conditional statements are those that have both a hypothesis and a conclusion. It is also known as a "If-then" statement. If the conclusion and the hypothesis are both true, the conditional statement is untrue.They include conditional statements, conditional expressions, and conditional constructions. Particularly, conditionals carry out various calculations or actions according on whether a boolean condition set by the programmer evaluates to true or false. The decision is always made in terms of control flow by selecting changing the control flow based on some situation.The contrapositive statement is : If two lines are not coplanar, then the lines do not intersect.
The converse statement is : If two lines are coplanar, then the lines intersect.

A new mobile device has a value of $256.25. It’s value changes by -22 1/2% each year. What is the value of the phone after two years?
If new mobile device has a value of $256.25 and its value changes by [tex]22\frac{1}{2}[/tex]% each year, then the value of phone after two years is $153.76
The value of new mobile device = $256.25
The percentage of value change = [tex]22\frac{1}{2}[/tex]%
Convert the mixed fraction to decimal form
[tex]22\frac{1}{2}[/tex]% = 22.5%
After one year mobile value = 256 - (256×22.5/100)
= 256-57.6
= $198.4
After two year the mobile value = 198.4-(198.4×22.5/100)
= 198.4-44.64
= $153.76
Hence, if new mobile device has a value of $256.25 and its value changes by [tex]22\frac{1}{2}[/tex]% each year, then the value of phone after two years is $153.76

I have one fair 6-sided die and one unfair 6-sided die. On the unfair die, the probabilities of rolling numbers 2,…,6 are equal and the probability of rolling a 1 has a different value. I roll each die once.
If the probability of rolling one 3 and one 4 is 1/24, what is the probability of rolling two 1’s?
Answer:
[tex]\dfrac{1}{16}[/tex]
Step-by-step explanation:
Probability Distribution Table for X
Where X is the score on a fair, six-sided dice:
[tex]\begin{array}{|c|c|c|c|c|c|c|}\cline{1-7} x & 1 & 2 & 3 & 4 & 5 & 6\\\cline{1-7} \text{P}(X=x) \phantom{\dfrac11}&\frac{1}{6} & \frac{1}{6} & \frac{1}{6} & \frac{1}{6} & \frac{1}{6} & \frac{1}{6} \\\cline{1-7}\end{array}[/tex]
Probability Distribution Table for Y
Where Y is the score on an unfair, six-sided dice, and the probabilities of rolling numbers 2, 3, 4, 5 and 6 are equal, and the probability of rolling a 1 has a different value:
[tex]\begin{array}{|c|c|c|c|c|c|c|}\cline{1-7} y & 1 & 2 & 3 & 4 & 5 & 6\\\cline{1-7} \text{P}(Y=y) \phantom{\dfrac11}&1-5k&k&k&k&k&k\\\cline{1-7}\end{array}[/tex]
Note: The probabilities of all the possible values that a discrete random variable can take add up to 1.
The outcomes of rolling one 3 and one 4 are:
Rolling a 3 with the first die and a 4 with the second die, ORRolling a 4 with the first die and a 3 with the second die.Given the probability of rolling one 3 and one 4 is ¹/₂₄:
[tex]\implies \text{P}(X=3)\; \text{and} \; \text{P}(Y=4) \; \text{or} \; \; \text{P}(X=4) \; \; \text{and} \; \; \text{P}(Y=3)=\dfrac{1}{24}[/tex]
[tex]\implies \dfrac{1}{6} \times k +\dfrac{1}{6} \times k=\dfrac{1}{24}[/tex]
[tex]\implies \dfrac{k}{6} + \dfrac{k}{6}=\dfrac{1}{24}[/tex]
[tex]\implies \dfrac{2k}{6}=\dfrac{1}{24}[/tex]
[tex]\implies 24(2k)=6[/tex]
[tex]\implies 48k=6[/tex]
[tex]\implies k=\dfrac{1}{8}[/tex]
Therefore:
[tex]\implies 1-5k=1-\dfrac{5}{8}=\dfrac{3}{8}[/tex]
Hence, the probability distribution table for the unfair 6-sided dice is:
[tex]\begin{array}{|c|c|c|c|c|c|c|}\cline{1-7} y & 1 & 2 & 3 & 4 & 5 & 6\\\cline{1-7} \text{P}(Y=y) \phantom{\dfrac11}&\frac{3}{8} & \frac{1}{8} & \frac{1}{8}& \frac{1}{8} & \frac{1}{8}& \frac{1}{8} \\\cline{1-7}\end{array}[/tex]
There is only one possible outcome of rolling two 1's, so the probability of rolling two 1's is:
[tex]\implies \text{P$(X=1)$ and P$(Y=1)$}=\dfrac{1}{6}\times\dfrac{3}{8}=\dfrac{3}{48}=\dfrac{1}{16}[/tex]
Note: Please see attachment for the sample-space diagram showing the possible outcomes of rolling two dice. The possible outcomes of rolling one 3 and one 4 are highlighted in yellow. The possible outcome of rolling two 1's is highlighted in blue.

the daily useage time on the apple iphone is normally distributed with mean 5.4 hours and standard deviation 1.2 hours. what proportion of iphone owners use their iphone between 4 and 7 hours in a day? round your answer to three decimal places.
Solving for the probability using the z-table, the proportion of iPhone owners who use their iPhone between 4 and 7 hours in a day is 0.787.
For a normally distributed set of data, given the mean and standard deviation, the probability can be determined by solving the z-score and using the z-table.
First, solve for the z-score using the formula below.
z-score = (x – μ) / σ
where x = individual data value (4 and 7)
μ = mean = 5.4
σ = standard deviation = 1.2
z-score = (4 - 5.4) / 1.2 where x = 4
z-score = -1.4 / 1.2
z-score = -7/6 or -1.1667
z-score = (7 - 5.4) / 1.2 where x = 7
z-score = 1.6 / 1.2
z-score = 4/3 or 1.3333
Find the probability that corresponds to the z-score in the z-table. (see attached images)
z-score = -7/6 or -1.1667 probability = 0.12197
z-score = 4/3 or 1.3333 probability = 0.90853
To determine the proportion of iPhone owners who use their iPhone between 4 and 7 hours in a day is the difference between the probabilities of the two values.
proportion = 0.90853 - 0.12197
proportion = 0.787

When x²+x-3 is subtracted from 3x² - 5
We get (3x² - 5) - (x² + x - 3)
==> step 1 remove parenthesis and change signs
3x² - 5 - x² - x + 3
==> step 2 combine like terms
2x² - x - 2
