Barton has 4 strawberries and Ona has 8. If they want to redistribute their strawberries so they each have an equal number, how many strawberries should Ona give to Barton? There are a total of strawberries. There are a total of people. The expression to find the mean, or balance point, is . should give 2 strawberries to for the number of strawberries to be balanced.
Answer:
2 strawberries
Step-by-step explanation:
Given that:
Number of strawberries :
Ona has 8
Barton has 4
For both Ona and Barton to have the same Nunber of strawberries :
(Ona + Barton) /2 = (8 + 4) / 2 = 12 /2 = 6
That means both Ona and Barton will have 6 strawberries each
Hence,
Barton who has 4 strawberries needs 2 more while Ona who has 8 will give out 2
Hence, Ona should give two strawberries to Barton.
Answer:
total strawberries 12
total 2 people
expression to find the mean 12/2
ona should give barton 2 strawberries so the number balance's out

ITS SO CONFUSINGNSKDN
Answer:
y=67.7 Degrees
Step-by-step explanation:
You're given the opposite and adjacent sides to angle Y, so we use Tan to find the angle:
Tan(y)= 100/41
We then inverse tan to isolate y
y=tan^-1 100/41
y=67.7 Degrees

The sum of two numbers is 48.if the smaller number is subtracted from the larger the difference is 12 find the number
Answer:
18
Step-by-step explanation:
30 + 18 = 48
30 - 18 = 12
Both true, so our solution is correct.
The value of the larger number is 30 and the value of the smaller number is 18.
What is a number system?A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set in a consistent manner using digits or other symbols. In different numeral systems, the same sequence of symbols can represent different numbers.
Given that the sum of two numbers is 48. if the smaller number is subtracted from the larger the difference is 12. The two numbers will be calculated as,
x + y = 48
x - y = 12
________
2x = 60
x = 30
y = 30 - 12
y = 18
Therefore, the value of the larger number is 30 and the value of the smaller number is 18.

A fair coin should land showing tails with a relative frequency of 50% in a long series of flips. Felicia read
that spinning-rather than flipping-a US penny on a flat surface is not fair, and that spinning a penny
makes it more likely to land showing tails. She spun her own penny 100 times to test this, and the penny
landed showing tails in 60% of the spins.
Let p represent the proportion of spins that this penny would land showing tails.
Complete question is;

What are appropriate hypotheses for Connor's significance test?
A. H_0 : p = 50% H_1 : p > 60%
B. H_0: p = 50% H_1: p > 50%
C. H_0: p = 50% H_1: p < 50%
D. H_0 : p = 60% H_1 : p < 60%
Answer:
Option B is correct
Step-by-step explanation:
From the question it is clear that;
The population proportion is 50% because it is not associated with any sample size.
However, the sample size is 100 and the sample proportion from this 100 is 60%.
But we don't define our hypothesis based on the sample proportion.
Now we want to find the probability that spinning a penny makes it more likely to land showing tails.
Thus we define the hypothesis as;
Null hypothesis; H0 : p=50%
Alternative hypothesis; H1 : p>50%

Which function rule for points would create the translation shown above?
(x, y) + (x+4, y+3)
(x, y) + (x-4, y-3)
(x, y) + (x+10, y+7)
(x, y) + (x-10, y-7)
Answer:
Option A
Step-by-step explanation:
Coordinates of the given points A and A',
A → (-6, -2)
A' → (-2, 1)
Rule for the translation of point A to A',
A(-6, -2) → A'(-6+h, -2+k)
Since, coordinates of A' are (-2, 1)
Therefore, -6 + h = -2
h = 6 - 2 = 4
And (-2 + k) = 1
k = 3
Therefore, rule for the translation will be,
(x, y) → (x + 4, y + 3)

What is the Greatest Common Denominator or factor between 244 & 48
Answer:
GCF = 4.
Step-by-step explanation:
Find the prime factors:
48 = 2*2*2*2*3
244 = 2*2*61
The greatest common factor, the GCF) (picking out the common values) =
2 *2 = 4.
A really clever way of finding the GCF of 2 numbers is Euclid's algorithm. It can be used for very large numbers where it would be time consuming and/or rather difficult to find prime factors:
Given two whole numbers where a is greater than b, do the division a ÷ b = c with remainder R.
Replace a with b, replace b with R and repeat the division.
Repeat step 2 until R=0.
When R=0, the divisor, b, in the last equation is the greatest common factor.
So applying this to our problem:
244 / 48 = 5 remainder 4
Replacing a (244) with 48 and b (48) with R (4):-
48/4 = 12 remainder 0.
So the GCF is 4.
Which set of ordered pairs is a linear function? A {(3, 1), (2, 0), (-1, 1)} B {(4, 4), (0, -6), (2, -1)} C {(-1, 2), (3, -4), (12, 5)} D {(0, 0), (1, 1), (2, 5)}
C.
You could set up the relation as a table of ordered pairs. Then, test to see if each element in the domain is matched with exactly one element in the range. If so, you have a function.

P varies inversely with x. If P = 7 when x = 8, find the value of P when x = 7. A. 0.125 B. 1 C. 7 D. 8
Step-by-step explanation:
P = 8
Step-by-step explanation:
Given that P varies inversely with x then the equation relating them is
P = \frac{k}{x} ← k is the constant of variation
To find k use the condition P = 7 when x = 8 , then
7 = \frac{k}{8} ( multiply both sides by 8 )
56 = k
P = \frac{56}{x} ← equation of variation
When x = 7 , then
P = \frac{56}{7} = 8

Troy drew the diagram below. The inner circle has a radius of 2 units, and the outer circle has a radius of 5 units. Troy says the two circles are similar.
Which statement best explains whether Troy is correct, and why?
He is correct because the inner circle is a dilation of the outer circle.
O
He is correct because the inner circle has the same center as the outer circle.
O
He is not correct because the inner circle's radius is less than the outer circle's radius.
He is not correct because the inner circle's radius is not half of the outer circle's radius.
o
Answer:A he is correct because the inner circle is a dilation of the outer circle
Step-by-step explanation: just did the test
The statement "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.
What is dilation?Dilation is the process of modifying the size of an item or form by reducing or expanding its dimensions according to specific scaling variables.
The radius of the inner circle is 2 units, while the radius of the outer circle is 5 units.
Since dilations provide similar figures because multiplying by the scale factor yields proportionate sides while keeping the angle measure and form constant.
Troy is accurate if he claims the two circles are similar.
Hence, the statement (A) "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.
