Rice weighing 33/4 pounds was divided equally and placed in 4 containers. How many ounces of rice were in each?
Answer:
The answer is 15 ounces
Step-by-step explanation:
33/4 ÷ 4 pounds.
(4 × 3 + 3)/4 ÷ 4 pounds.
15/4 ÷ 4 pounds.
15/4 × 1/4 pounds.
15/16 pounds.
Now we know that, 1 pound = 16 ounces.
So, 15/16 pounds = 15/16 × 16 ounces = 15 ounces.
Thus, The answer is 15 ounces

a. State the hypotheses and identify the claim.
b. Find the critical value(s).
c. Compute the test value.
d. Make the decision.
e. Summarize the results
Answer:
H0 : μ = 18000
H1 : μ < 18000 - - - > Claim
Test value = - 3.578
Critical value = ±2.58
There is significant evidence to accept the claim that mean debt at graduation is less than $18000
Step-by-step explanation:
H0 : μ = 18000
H1 : μ < 18000
From the data:
Sample size, n = 30
Sample mean, x = 16298.37
The test statistic :
(16298.37 - 18000) ÷ (2605/sqrt(30))
−1701.63 / 475.60575
= - 3.578
The critical value :
Using the standard normal table;
Critical value at α = 0.01
Critical value = ±2.58
Decison region :
|test statistic | > |Critical value | ; reject H0
|3.578| > |2.58| ; We reject H0 and conclude that Mean debt at graduation is less than $18000

Write the function for the graph.
(1,12)
(0,3)
O A. f(x) = 3•(12)^x
O B. f(x) = 4•(3)^x
O C. f(x) = 3•(4)^x
D. f(x) = 4•(12)^x
Answer:
[tex]f(x) =3 * (4)^x[/tex]
Step-by-step explanation:
Given
[tex](x_1, y_1) = (1,12)[/tex]
[tex](x_2, y_2) = (0,3)[/tex]
Required
The function of the graph (exponential function)
An exponential function is represented as:
[tex]f(x) = ab^x[/tex]
For [tex](x_1, y_1) = (1,12)[/tex], we have:
[tex]12 = a * b^1[/tex]
[tex]12 = a * b[/tex]
[tex]12 = a b[/tex]
For [tex](x_2, y_2) = (0,3)[/tex]
[tex]3 = a * b^0[/tex]
[tex]3 = a * 1[/tex]
[tex]3 = a[/tex]
[tex]a = 3[/tex]
Substitute: [tex]a = 3[/tex] in [tex]12 = a b[/tex]
[tex]12 = 3 * b[/tex]
Divide both sides by 3
[tex]4 = b[/tex]
[tex]b =4[/tex]
So, we have:
[tex]f(x) = ab^x[/tex]
[tex]f(x) =3 * (4)^x[/tex]

Unit 3: Parallel & Perpendicular Lines Homework 5: Linear Equations Slope-Intercept & Standard Form
Directions: Determine if the equations are parallel, perpendicular, or neither.
11. y = -3x + 6 and y = 1/3 x -8
12. y = 5/4 x + 1 and y = 5/4 x - 7
13. 3x + 2y = 6 and y = -3/2 x + 5
14. 3y = 4x + 15 and 9x + 12y = 12
15. 10x - 2y = 16 and x + 5y = -20
16. 5x + 3y = 3 and 3x + 5y = -25
17. -9y = -3x + 18 and 2x -6y = 30
18. x-y = 5 and x + y = -10
11. y = -3x + 6 and y = 1/3 x -8 (perpendicular)
12. y = 5/4 x + 1 and y = 5/4 x - 7 (parallel)
13. 3x + 2y = 6 and y = -3/2 x + 5 (parallel)
14. 3y = 4x + 15 and 9x + 12y = 12 (perpendicular)
15. 10x - 2y = 16 and x + 5y = -20 (perpendicular)
For two equations to be parallel, the slope has to be the same
For two equations to be perpendicular, the product of their slopes must be equal to -1
The equation of a line is the slope-intercept form is:
y = mx + c
where m is the slope and c is the intercept
11) y = -3x + 6 and y = 1/3 x -8
The equations are perpendicular because -3 x 1/3 = -1
12) y = 5/4 x + 1 and y = 5/4 x - 7
The two lines are parallel because they both have a slope of 5/4
13) 3x + 2y = 6 and y = -3/2 x + 5
The equation 3x + 2y = 6 can be re-written as y = -3/2 x + 3
Therefore, the two equations are parallel since they have the same slope of -3/2
14) 3y = 4x + 15 and 9x + 12y = 12
3y = 4x + 15 can be re-written as y = 4/3 x + 5
9x + 12y = 12 can be re-written as y = -3/4 x + 1
The two lines are perpendicular because -3/4 x 4/3 = -1
15) 10x - 2y = 16 and x + 5y = -20
10x - 2y = 16 can be re-written as y = 5x - 8
x + 5y = -20 can be re-written as y = -1/5 x - 4
Both equations are perpendicular since -1/5 x 5 = -1

What is an equation of the line that passes through the points (4, -1) and
(-8. – 7)?
Answer:
[tex]y = \frac{1}{2} x - 3[/tex]
Step-by-step explanation:
The equation of a line can be written in the form of y=mx +c, where m is the gradient and c is the y-intercept.
[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]
Using the gradient formula above,
gradient of line
[tex] = \frac{ - 1 - ( - 7)}{4 - ( - 8)} [/tex]
[tex] = \frac{ - 1 + 7}{4 + 8} [/tex]
[tex] = \frac{6}{12} [/tex]
[tex] = \frac{1}{2} [/tex]
Substitute m= ½ into the equation:
y= ½x +c
To find the value of c, substitute a pair of coordinates.
When x= 4, y= -1,
[tex] - 1 = \frac{1}{2} (4) + c[/tex]
-1= 2 +c
c= -1 -2 (-2 on both sides)
c= -3
∴ The equation of the line is y= ½x -3.

#3 and #4 please. How do you know a sticky note has volume and can you determine the volume of an entire stack by knowing the volume of a single sticky note
Answer:
Step-by-step explanation:
3. A single sticky note is a three-dimensional object. Meaning it has a length, width and height. Therefore, it is taking up space, and anything that takes up space has a volume. If the sticky not did not have a volume then it would not be a three-dimensional object.
4. Yes, if we knew the volume of a single sticky note, then we would simply have to multiply the volume of that individual note by the total number of sticky notes in the pile. This would give us the volume of the entire pile.
An assistant receives a wage of $16.24 per hour this amount is 112% of last year's wage what is the dollar increase in the hourly wage over last year use proportion method
9514 1404 393
Answer:
$1.74
Step-by-step explanation:
The ratio of the increase to this year's wage is ...
12%/112% = x/$16.24
Multiplying by $16.24, we have ...
x = $16.24(12/112) = $1.74
The dollar amount of the wage increase is $1.74.

if f (x)=x^2+1 and g(x) =x-4 which value is equivalent to f x g
Answer:
A value of [tex]x^3 - 4x^2 + x - 4[/tex] is equivalent to [tex]f \times g[/tex]
Step-by-step explanation:
We are given the following functions:
[tex]f(x) = x^2 + 1[/tex]
[tex]g(x) = x - 4[/tex]
Which value is equivalent to f x g?
We multiply these functions, applying the distributive property. So
[tex]f \times g = (x^2+1)(x-4) = x^3 - 4x^2 + x - 4[/tex]
A value of [tex]x^3 - 4x^2 + x - 4[/tex] is equivalent to [tex]f \times g[/tex]
