Fill in the blank to complete the equation below.

___ + 15
= 3(8 + 5)

Answer:

Option A

Step-by-step explanation:

The value of the standard error of the mean is 1.256.

We have given that,

Some stores print multiple coupons and advertisements on their receipts, making the receipts unusually long.

A curious shopper makes the same purchase at a random sample of 10 stores and measures the length of each receipt (in inches).

Here are the results,

8.25, 7.5, 5, 9.5, 12, 5.5, 9, 14, 11.5, 18.

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.

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.

Answer:

36 miles

Step-by-step explanation:

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]

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

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:

17 units

Step-by-step explanation:

Given 2 congruent chords in the circle, then they are equidistant from the centre and perpendicular

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

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

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)

Answer:

I will say C it is more realistic.
