Answer:
calculate the value of expression:3×+4×-5A marine biologist was interested in seeing the relationship of a baby manatee's weight and age. She gathered data and wanted to construct a graph to display the data in order to observe the change in weight per year.
Is a scatter plot or a line graph more appropriate to construct for the data, given the context of the problem? Explain.
A: A scatter plot, because it would show the association or relationship between two variables
B: A scatter plot, because it would show how a variable changes over time between each data point given
C: A line graph, because it would show the association or relationship between two variables
D: A line graph, because it would show how a variable changes over time between each data point given
Option (B) A scatter plot, because it would show how a variable changes over time between each data point given.

When rolling a 6-sided die twice, determine P(sum of 6).
A: twelve thirty sixths
B: seven thirty sixths
C: five thirty sixths
D: two sixths
The Probability of getting the sum of 6 is 5/36.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
We know that the outcome will be
(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6)
(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)
(3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6)
(4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)
(5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6)
(6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)
So, case case where sum is 6 are
(1,5), (2,4), (3,3), (4,2) and (5,1).
So, the P(sum of 6) is = 5/36

Answer: 19.7292
Step-by-step explanation: C=2πr=2·π·3.14≈19.7292
Hello:
--> find circumference to the nearest tenth
Our formula for the circumference of the circle:
[tex]\text{Circumference}=2\pi r[/tex]
-'r': radius's length --> 13.4
Let's calculate:
[tex]\text{Circumference}=2*\pi *13.4=26.8\pi =84.19 \text{ inches}[/tex]

Answer: calculations in seconds (or calculations in seconds)
Step-by-step explanation:
The complete exercise is: "A certain computer can perform 10^5 calculations per second. How many calculations can it perform in 10 seconds".
You need to analize the information provided in the exercise in order to solve it.
Let be "x" the number of calculation a certain computer can perform is ten seconds.
According to the exercise this computer can perform calculations in second. Then, in order to calculate the amount of calculattion it performs in seconds, you can set up the following proportion:
Now, you need to find the value of "x".
To solve for "x" you can multiply both sides of the equation by .
Then, you get:
Therefore, the computer can perform calculations in seconds (or calculations in seconds)

Louis rolled a fair six-sided die and recorded the number that was facing up on the die. He continued this for a total of 100 rolls. The table shows the frequency of each number rolled.
Outcome 1 2 3 4 5 6
Frequency 17 20 14 18 16 15
Based on the table, what is the experimental probability that the number rolled was even?
A: 53 over 100
B: 47 over 100
C: 5 over 12
D: 1 over 2
The experimental probability that the number rolled was even is 53/100.
The correct option is A.
We have,
Outcome 1 2 3 4 5 6
Frequency 17 20 14 18 16 15
As, the Frequency of Even number(2, 4, 6) is
= 20 + 18 + 15
= 53
Total of Frequency = 17 + 20 + 14 + 18+ 16 + 15= 100
So, the probability that the number rolled was even
= 53/100

Data was collected on the weight, in ounces, of kittens for the first three months after birth.
A line of fit was drawn through the scatter plot and had the equation w = 3.25 + 0.3d, where w is the weight of the kitten in ounces and d is the age of the kitten in days.
What is the w-intercept of the line of fit and its meaning in terms of the scenario?
3.25; a kitten who is just born is predicted to weigh 3.25 ounces
0.3; a kitten who is just born is predicted to weigh 0.3 ounces
3.25; for each additional day after the kitten is born, its weight is predicted to increase by 3.25 ounces
0.3; for each additional day after the kitten is born, its weight is predicted to increase by 0.3 ounces
Answer:
A. 3.25
Step-by-step explanation:
A kitten who is just born is predicted to weigh 3.25 ounces and its weight is predicted to increase by 0.3 ounces. Then the correct option is A,D.
1. The 0.3d is the day each day
So
==> 0.3d +3.25(the first day born) ==> w ( means the d is the day so it increase 0.3 per day)
What is a linear equation?
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + cWhere m is the slope of the line and c is the y-intercept of the line.
Information was gathered on the weight, in ounces, of cats for the initial three months after birth. A line of fit was drawn through the dispersed plot and had the condition w = 3.25 + 0.3d, where w is the heaviness of the cat in ounces and d is the age of the little cat in days.
A kitten who is just born is predicted to weigh 3.25 ounces and its weight is predicted to increase by 0.3 ounces. Then the correct option is A.

Fantastic! So what is 2.2 x 4? 8.8 right?
8.8 ? 10
So 10 is greater than all numbers less than 10. That would be 9.9, 9, decimals in between 8, 8, decimals in between 7, 7, etc.
10 is greater than 8.8.
Fax no printer mi amigo!
If you need help with the actual signs, no, ofc 8.8 does not equal 10. So = is off. But the ≤ and ≥ are possible.
Think of those signs like crocodiles, like my teacher once taught me. Instead of ≤ and ≥, think of them as crocodiles. 8.8 < 10 because the crocodile would rather eat more [food/fish/whatever] than less. So its mouth is open for the 10, to eat it. This (<) with a line under it (≤) means that the number is either equal to or less than 10. < and ≤ would both be correct here, but since < is unavailable, it would be ≤ . 8.8 isn't equal to 10, but it is less than 10, so ≤ is still correct.

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(1, 7) = 7. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 7 = 7. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - minus two minus ten sevenths is minus twenty-four sevenths.
