i need the mean, median, mode, and range
Answer:
the median is 5 the mode is 5 and 2 the mean is 6.25 and the range is 15
Step-by-step explanation:
the mode is 5 and 2 because they both occur the most often
The median is 5 because even though the amount of numbers is even and there is no exact middle the two middle numbers are both 5 and 5+5 equals 10 divided by 2 equals 5
the mean is 6.25 because all numbers added together 75 divided by the amount of numbers 12 equals 6.25
the range is 15 because the range is the diff between the highest and lowest value

Answer:
To write a polynomial in standard form, simplify and then arrange the terms in descending order.
y=ax²+bx+c Simplify each term.
y=5x²−20x+20+7
Add 20 and 7.
y=5x²−20x+27

if a half a gallon of milk costs $1.24 then whats the cost per pint?
Answer:
Step-by-step explanation:
It costs . 31 cents for 1 pint of milk.
Answer:
1 pint would be ($1.25/4 pints) = $0.31
Step-by-step explanation:
There are eight pints in a US gallon, and thus four in half a gallon.
That comes to four pints of milk.
That's $1.24/(half gallon), or $2.48/gallon.
Since half a gallon (4 pints) is $1.25, 1 pint would be ($1.25/4 pints) = $0.31
Ms. Carey grades 4 tests during her lunch. She grades 1/3 of the remainder after school. If she syill5has 16 test to grade after school, how many test are there?
Answer: 24 tests
Step-by-step explanation:
Ms. Carey graded 1/3 of the tests and still had 16 tests to go.
This means that the 16 tests represent the remaining proportion of the total number of tests:
= 1 - 1/3
= 2/3
2/3 of the total is equal to 16 tests. Assuming the total is x, the expression would be:
2/3x = 16
x = 16 ÷ 2/3
x = 16 * 3/2
x = 24 tests
what is the value of d to the nearest hundredth
Step-by-step explanation:
This can be done by using the trignometric ratio of tangent in the ∆DEF . The two of its sides along 90° are 7.2 and d .
• In ∆ DEF :-
[tex]\tt\to tan42^o = \dfrac{EF}{ED}\\\\\tt\to tan42^o =\dfrac{d}{7.2}\\\\\tt\to 0.9 = \dfrac{d}{7.2}\\\\\tt\to d =7.2\times 0.9\\\\\tt\to\boxed{\orange{\tt d = 6.48 }}[/tex]

What is the standard error of the mean?The standard error of the mean, or simply standard error, indicates how different the population means is likely to be from a sample mean. It tells you how much the sample means would vary if you were to repeat a study using new samples from within a single population.
Therefore, The value of the standard error of the mean is 1.256.

There is a right triangle formed by legs 15 and 8, with radius r being the hypotenuse.
Using Pythagoras' identity in this right angle
r² = 15² + 8² = 225 + 64 = 289 ( take the square root of both sides )
r = [tex]\sqrt{289}[/tex] = 17

Need help,==== thank you!!
Answer:x=square root(239)
Step-by-step explanation:
The way to solve this is via the Pythagorean theorem(a^2 + b^2 = c^2)
a= a leg
b= another leg
c= hypotenuse
16^2 = square root(17)^2 + x^2
256 = 17+ x^2
239 = x^2
x=square root(239)

Hannah paid $8.63 at the grocery store for beans and potatoes. She bought 4 pounds of beans at $0.62 per pound and 5 pounds of potatoes.
How much did Hannah pay per pound for the potatoes?
$3.67
$1.32
$6.15
$1.23
Answer:
$1.23
Step-by-step explanation:
First start off by multiplying $0.62 by 4 to find out the total she paid for all four pounds of beans. This would give you $2.48 spent on beans. Subtract $2.48 from the total amount spent ($8.63). You now have $6.15 left on what she could have spent on 5 pounds of potatoes. Do $6.15 divided by 5 to get an answer of $1.23. Hannah paid $1.23 per pound for the potatoes.
