Ky wants to buy three shirts, which were originally priced at $49.96 each. The store will discount the price of the 3rd shirt by 50% off and apply a %7.1 tax to the total cost of all three shirts. Including the tax, what will be the mean cost of each shirt?
9514 1404 393
Answer:
$44.49
Step-by-step explanation:
The total cost before tax will be ...
$49.96 +49.96 + 0.50(49.96) = $124.90
With tax added, the cost is ...
$124.90 × 1.071 = $133.77
Then the average cost per shirt for the 3 shirts is ...
$133.77/3 = $44.59
The mean cost of a shirt is $44.59.
Answer:
the answer is $44.49

From a random sample of 185 children from school G, 108 indicated they wanted to study science in college. From a different random sample of 165 children from school H, 92 indicated they wanted to study science in college. Assuming all conditions for inference are met, which of the following is closest to the standard error for a confidence interval for the difference in population proportions between the two schools of children who want to study science in college?A. 1.96 underroot(200/350)(1 − 200/350)/350.B. Underroot(108/185)(1 − 108/185)185 − (92/165)(1−92/165)/165.C. Underroot(108/185)(1 − 108/185)185 + (92/165)(1−92/165)165.D 1.96 underroot(108/185)(1 − 108/185)185 + (92/165)(1 − 92/165)165.E. Underroot(200/300)(1 - 200/300)/350.
Answer:
C. Underroot(108/185)(1 − 108/185)185 + (92/165)(1−92/165)165.
Step-by-step explanation:
Sample size, n1 = 185
x1, = 108
P1 = x1 / n1 = 108 / 185 =
Sample size, n2 = 165
x2, = 92
P2 = x2 / n2 = 92/165
Standard Error = sqrt[(p1(1-p1))/n1 + (p2(1-p2))/n2]
sqrt[(108/185(1 - 108/185)) /185 + (92/165(1 - 92/165)) / 165]

$45.00 iPod shuffle 1GB
10% or markdown plus sales tax 10%
What will the sale price be if you purchase this item?
Answer:
$44.55
Step-by-step explanation:
10% of 45 is 4.5
45 * 0.1 = 4.5
So subtract 4.5 from 45
45 - 4.5 = 40.5
Now get 10% of 40.5
40.5 * 0.1 = 4.05
Add 4.05 to 40.5
4.05 + 40.5 = 44.55
Match each pair of points a and B to point C such that ABC equals 90°

Find the solution to the system of equations.

O D. x= 1, y = 6, z = 2
Answer:
B.

The solution to the system of equations is x-1, y = 4 and z= 2.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have the equation
3x + 2y - 4z = 3
x -4y +2z = -11
2x + y + 2z = -11
Solving the above equation we get
3x + 2y - 4z - 3x + 12y + 6z = 3 + 33
14y + 2z = 36
and, 2x - 8y + 4z - 2x - y - 2z = -22 + 11
-9y + 2z = -11
So, y =4 and z = 2
and, x = 1

Find the height of this cone using the Pythagorean Theorem. 9 in. h = [?] in. 6 in. a C Pythagorean Theorem: a2 + b2 = c2 b
Answer:
h = √72 in.
Step-by-step explanation:
Height of the cone using pythagorean theorem, a² + b² = c², where:
a = h
b = ½(6) = 3 in.
c = 9 in.
Plug in the values
h² + 3² = 9²
h² + 9 = 81
h² + 9 - 9 = 81 - 9
h² = 72
h = √72

It can be convinient to let a spreedsheet compute the values for you
Here we have written an expiliclit formula for the height of the 9th bounce
H= 5.5 x 0.64'(n-1)
We have written the formuka this way beacause we are given the height of the firrrst bounce not the satrting height so as you see each bounce multiples the height by a factor of 0,64 then the 7th bounce will be
H= 5.5 x 0.64'6 = 0.378 = 0,4 feet
