Answer:
1:5 4:20
Step-by-step explanation:
Because say you got 1 right out of 5 on test you get a 20%
since 20 can go into a 100 5 times if whatever number is the 1rst time it can go into 5 it is a 20 like 4:20 because 4,8,12,16,20 see that's 5 numbers and 4 is the first.
In then 1:5 is another example it can go 5 times or one more is like 10:50=20% or 15:75.
Hope this helps have a great afternoon:)

Which quadratic function in vertex form has a vertex at (-2, 6) and passes through the point (-4, 8)?
A. y = 1/2 ( x - 2 ) ^2 + 6
B. y = -1/2 ( x - 2 ) ^2 - 6
C. y = -1/2 ( x - 2 ) ^2 + 6
D. y = 1/2 ( x + 2 ) ^2 + 6
Answers
Answer:
y = -1/2(x + 4)² + 2 or y = -1/2x²- 4x - 6
Step-by-step explanation:
Given
Vertex = (-4, 2)
The graph passes through the point (-8, -6)
The function in vertex form is:
y = a(x + 4)² + 2
Substitute the coordinates of (-8, -6) and find the value of a:
-6 = a(-8 + 4)² + 2
-8 = 16a
a = -1/2
The function is:
y = -1/2(x + 4)² + 2
or in standard form:
y = -1/2(x² + 8x + 16) + 2 = -1/2x²- 4x - 6
On the first 7 statistics tests of the semester, scored 61, 76, 79, 80, 80, 84, and 91. The mean,
median, and mode of his scores were 79, 80, and 80,
respectively. On the 8th statistics test, Jamal scored 90. How do the mean, median, and mode of all 8 of his )
scores compare to the mean, median, and mode of his
first 7 scores?
Answers
The median will not be affected. Because it is the middle value. So the fourth value(count values from 61,91 with 61 being 1) is 80 which is the middle one. While with 8 data points, it would be the 4th + 5th both divided by 2. However (80 + 80)/2 is 80. So median is unchanged.
Now for the mode. Remember the mode is the most common number. Because 90 does not match another value, 80 is still the most common value which means it remains unchanged. (This is why mode is often the most useless measurement unless you have a lot of data points)

Angela is comparing the amount of rainfall over the past month in two cities on days when it rained. In City 1, the range in rainfall is 4.5 centimeters and the interquartile range (IQR) is 1.5 centimeters. In City 2, the range is 5 centimeters and the IQR is 3 centimeters. What might you conclude about the cities based on the ranges and interquartile ranges?
Answers
The conclusion about the cities based on the ranges and interquartile ranges are;
The rainfall amounts on days when it rains have greater variability for City 2 than those for City 1.
What is interquartile range and range?
The interquartile range (IQR) is defined as the length of the middle 50% of that interval of a particular space. The way the IQR is calculated is the difference between the third or upper quartile and the first or lower quartile.
Meanwhile the range is the difference between the highest and lowest value.
Looking at the question, we can say that The rainfall amounts on days when it rains have greater variability for City 2 than those for City 1.

if the least value of n is 5, which inequality best shows all the possible values of n?
n ≥ 5
n ≤ 5
n < 5
n > 5
Answers
Answer:
First option
Step-by-step explanation:
The inequality says greater than or equal to 5. Which means n is greater than or equal to (≥) 5.
It's not the second option because less than or equal to means that n is less than or equal 5, which doesn't check out since 5 is the smallest value of n.
It's not the third option since it says that 5 is greater than n, when we know that one of n's values is 5.
It's not the fourth option since it says that that n is greater than 5, when we know again that one of the values of n is 5.
Your answer is the first option "n ≥ 5."

The tip of the minute hand of a clock is 14cm from the centre of the clock. Find in metres the distance travelled by the tip of the minute hand of the clock in 3 hours
pls help :')
Answers
Answer:
263.76cm
Step-by-step explanation:
r = 14cm
2πr = circumference = distance traveled in 1 hour
3(2πr) = 3x28xπ
π=3.14
= 84x3.14 = 263.76cm
HOPE THIS HELPS!!!
Answer:
2.6 m
Step-by-step explanation:
The minute hand on an oldfashioned (analog) clock will go completely around the clock 3 times in three hours.
The clock is a circle.
The length of the hand is the radius.
The distance around a circle is the circumference (it is perimeter for a circle!)
Circumference
= (pi)•d OR
= 2(pi)r
So the distance all the way around the clockface ONE TIME
is C = (pi)d = 2(pi)r =(3.14)28
= 87.96459 m
But in three hours it goes around three times.
3(87.96459)
= 263.89378
BUT this is cm and they asked for meters. So divide by 100, because there's 100 cm in a meter.
263.89378/100
~= 2.6 meters

Answers
Answer:
Each gets 29 oranges
Step-by-step explanation:
126 - 10 = 116
116÷4 = 29
The equation is 4n + 10 = 126 and each family gets 29 oranges.
What is an equation ?Equation in mathematics implies equating two same quantities of different form.
According to the given question
Izzys family has orange trees in their yard they picked 126 oranges they kept 10 oranges for themselves and shared the rest evenly among 4 other families
So after keeping 10 oranges for themselves they have 116 oranges.
Now they share this to 4 families evenly
∴ 4n = 116
n = 116/4
n = 29
So, each family gets 29 oranges.
