Answer:
The fourth option shows how Bruno is incorrect
Step-by-step explanation:
Multiplication does not always result in a number greater than the initial value. If n can be any value, then Bruno's claim is false. For instance, multiplying a value greater than one by a decimal will perform the inverse operation (division):
3 × 0.87 = 2.61
When multiplying fractions of 1, this occurs when the multiplied number is greater than the multiplier:
0.55 × 0.21 = 0.1155
If decimals are not allowed, multiplying positive and negative values will give the positive result but with the inverse sign, which is less than the initial one since the result is less than 0:
12 × -2 = -24
Now back to the example. If we let n = 0.75 (3/4);
0.8 × 0.75 = 0.6

The two linear equations in this problem are:
a) d(t) = (3.1 mi/h)*tb) t(d) = d/(3.1 mi/h).How to find the linear equations?
a) First, we know the relation:
distance = speed*time.
In this case, we know that the speed is 3.1 miles per hour, so if the runner runs for t hours, we can write:
d(t) = (3.1 mi/h)*t
This is the linear equation that gives the distance as a function of time.
b) Now we want to get the time as a function of the distance, so we just need to isolate t,
t(d) = d/(3.1 mi/h).
This linear equation gives the time as a function of the distance d.

A packet of biscuits is shared between two people so that
one person gets three times as many as the other. Write
down the ratio involved. If there are 20 biscuits in the
packet, how many does each person get?
Answer:
Ratio 3 : 1
First person 5 biscuits
Second person 15 biscuits
Step-by-step explanation:
“one person gets three times as many as the other” means “the ratio is 3 to 1 or just 3 : 1”
………………………
Let x be the number of biscuits that the first person got then the second person should get 3x biscuits.
It’s clear that we have to solve this equation:
x + 3x = 20
Solving:
x + 3x = 20
⇔ 4x = 20
⇔ x = 20/4 = 5
Final answer:
First person: 5 biscuits
Second person: 3×5 = 15 biscuits

Write the equation of the line in fully simplified slope-intercept form.
Answer:
y = 5x/6 +5
Step-by-step explanation:
Points (-6,0) and (6,10)
Getting the slope
m = 10-0/6- (-6)
m=10/12
m=5/6
Solving for the equation:
where (-6,0) :
y-y1=m (x-x1)
y-0 = 5/6 (x- (-6))
y = 5/6 (x-+6)
y = 5x/6 +5
Answer:
y = 5x/6 + 6
Step-by-step explanation:
equation of a line is y = mx +b
m is the slope.
m = (y2- y1)/(x2-x1)
if we choose any two points in the line of the image..
p1 (6,10) -> x2 is 6, y2 is 10
p2 (0,5) -> x1 is 0, y2 is 5
m = (10-5)/(6-0)
m = (5)/(6)
m = 5/6
b is calculated when x = 0. (Where the line intercepts the y axis), Looking at the line in the image I can see that y = 6 when x = 0, so b = 6.
We have then
y = mx +b
y = (5/6)x + 6
y = 5x/6 + 6

Students measured the length of different earthworms using centimeters (cm).The lengths were:
14 cm, 12.5 cm, 13 cm, 18 cm, 17 cm, 16.75 cm, 19 cm, 12.5 cm, 15 cm
If the students were asked to describe the difference in length of the worms, which answer would be best and why? (5 points)
Group of answer choices
6.5 cm; this is found by determining the range which is found by finding the difference between the greatest length and the least length
12.5 cm; this is found by determining the mode which is found by finding the number that occurs most frequently in a data set
15 cm; this is found by determining the median which is found by ordering the numbers from least to greatest and finding the middle number
15.3 cm; this is found by determining the mean which is found by finding the sum of all of the lengths and dividing by the total number of worms
The correct option regarding the difference in the length of the worms is given by:
6.5 cm; this is found by determining the range which is found by finding the difference between the greatest length and the least length.
What is the range of a data-set?It is given by the difference of the highest value by the lowest value in the data-set.
In this problem, the difference is exactly what we want to estimate, hence we need to consider all measures(which removes the mode and the median), and find the largest lowest and the highest, which is the range, hence:
19 cm - 12.5 cm = 6.5 cm.
Which means that the correct option is given by:
6.5 cm; this is found by determining the range which is found by finding the difference between the greatest length and the least length.

The odds ratio for birds having long beaks being able to fly against birds not having long beaks being able to fly is 3.76.
What is an odds ratio?An odds ratio is a measure of the strength of an association with the exposure and outcome.
The odds ratio can be calculated by dividing the odds of the first group (exposure) by the odds of the second group (outcome).
Data and Calculations:Contingency Table
