Answer:

Michael should get $0.25 from the clerk.  

Step-by-step explanation:

Add $1.25+$0.50 together which equals $1.75 and multiply $0.25x8 which equals $2.00 and subtract $1.75 from $2.00 and that equals $0.25.

Answer:

.25 = 1 quarter

Step-by-step explanation:

8 x .25 = $2.00

1.25 + .50 = $1.75

2.00 - 1.75 = .25

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: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: B

Step-by-step explanation:

Answer:

k = -1

Step-by-step explanation:

Here, we want to get the value of k

Now, to get the remainders, we set the linear factors to zero, solve for x and insert the value of x into the polynomial

for x + 1 = 0

x= -1

insert -1 into p(x)

we have this as;

2(-1)^4 + k(-1) + 1

= 2 - k + 1 = 3-k

for the second

set x-1 to zero

x = 1

insert into q(x)

q(1) = 3(1)^4 + k(1)^2 + 2

= 5 + k

so we can now equate the two remainders;

5 + k = 3-k

k + k = 3-5

2k = -2

k = -2/2

k = -1

Answer:

Step-by-step explanation:

(4x-7)+(7-4x)

cancels each other

which makes it zero

Given pair of expression :

[tex] \longrightarrow \sf {(4x -7) \: and \: (7-4x) } [/tex]

Solution :

Firstly put the sign of addition (+) at the place of and.

[tex] \longrightarrow \sf {(4x -7) + (7-4x) } [/tex]

Now, remove the brackets.

[tex] \longrightarrow \sf {4x -7 + 7-4x } [/tex]

Group like terms. Here, 4x and -4x ; -7 and +7 are like terms.

[tex] \longrightarrow \sf {\cancel{4x -4x} \cancel{ -7 + 7}} [/tex]

[tex] \implies \sf \red {0 } [/tex]

Answer: 163 students

Step-by-step explanation:

First find the percentage of students who were in favor of having school  start one hour later based on the sample of 20 students.

= 13/20 * 100%

= 65%

The apply this percentage to the total number of students in school to find your answer:

= 65% * 250 students

= 162.5

= 163 students

The number of students in the school who are in favor of having school start one hour later is; C: 163 students

We are told that 13 out of the 20 surveyed students were in favour of having school start one hour later. Thus;

Probability = 13/20 * 100% = 65%

Now, the school has 250 students and as such, the number of students in the school who are in favor of having school start one hour later is;

65% * 250 students = 162.5 ≈ 163 students

Step-by-step explanation:

Picture a full circle with radius 8.  The area of this full circle is A = πr².

Now substitute 8 for r:  We get A = π(64) = 64π.

Now multiply this result by 1/4 to obtain the area of the figure shown:

A = (1/4)64π = 16π   (units squared)

Answer:

10x-13

Step-by-step explanation:

First Distribute:

-18x-21+28x+8

Then combine like terms:

10x-13

The two angles with y in them need to add up to 180 degrees

10y + 3y + 11 = 180

Simplify:

13Y + 11 = 180

Subtract 11 from both sides

13y = 169

Divide both sides by 13

Y = 13

Now solve for those two angles:

10y = 10(13) = 130

3y + 11 = 3(13) + 11 = 50

The other two angles are the same as these.

The larger angles = 130

The smaller angles = 50

Answer:

4²+b² = 5²

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem to find the length of the missing side.

The Pythagorean theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse.  Algebraically, this is represented as

a²+b² = c²

We have the measure of one leg, 4 in.  We also have the measure of the hypotenuse, 5 in.  This gives us

4²+b² = 5²

Second Data Set

Step-by-step explanation:

The mean absolute deviation describes the average distance between each data point. Let's consider both data sets. In data set one, classmate ages are recorded. Because most of Jordan's classmates are close together in age, the amount of deviation is small. In data set two, teach ages are recorded. Because teacher's ages can range from 23-99, the deviation in this set is expected to be larger than set one.
