Three weeks ago, an art supply store started selling a paint kit for 75% of the original price. Now the kit is 15% off of the sale price. The expression 0.75x - 0.15(0.75x) represents the current price of the paint kit where x is the kit’s original price (in dollars). Find the current price of the kit if it originally cost $48.
Answer:
$30.60
Step-by-step explanation:
0.75X-0.15(0.75X)
0.75(48)-0.15(0.75(48))
0.75(48)-0.15(36)
36-0.15(36)
36-5.4
30.6
Okay so I am confused about a few questions so I'll ask a few.
How do I find the x and y intercepts if they exist, the vertex, and the axis or line of symmetry, and put the function in general form?
f(x) = -2(x + 1)² -4
Sabrina bought a hoodie at the store when they were having a 25% off sale. If the regular
price of the hoodie was $50, how much did Sabrina save?
Answer:
$12.50
Step-by-step explanation:
Answer:
$12.50
Step-by-step explanation:
The sale is for 25% off, so she saved 25% of $50.
25% of $50 = 0.25 * $50 = $12.50

Answer: 3 then 0
Step-by-step explanation:
A sample of 68 electric motors had a mean efficiency of 0.595 (assume that the standard deviation is known to be 0.05). Let μ represent the mean efficiency of electric motors of this type.
Find the P-value for testing H0 : μ ≥ 0.6 versus H1 : μ < 0.6.
P-value =
The p-value for the test hypothesis is of 0.4681.
How to find the p-value of the test?We are working with proportions in this problem, hence the z-distribution is used, first we find the test statistic, and then with the test statistic, we find the p-value.
The test statistic is given according to the following rule:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which the parameters of the formula are described as follows:
[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.In the context of this problem, the values of these parameters are given by:
[tex]p = 0.6, \overline{p} = 0.595, n = 68[/tex]
Hence the test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.595 - 0.6}{\sqrt{\frac{0.6(0.4)}{68}}}[/tex]
z = -0.08
Using a z-distribution calculator, with a left-tailed test, as we are testing if the proportion is less than a value, the p-value is of 0.4681.

A glass is
1
6
full. Then 95cm3 of orange juice is poured in.
The glass is now
4
5
full. What is the total volume of the glass?
Answer:
let x = the amount of orange juice in a full glass.
the glass is 1/6 full = 1/6 * x
add 95 cubic centimeters and the glass becomes 4/5 full.
equation for that is:
1/6 * x + 95 = 4/5 * x
subtract 1/6 * x from both sides of this equation to get:
95 = 4/5 * x - 1/6 * x
multiply 4/5 * 6/6 and multiply 1/6 * 5/5 and the equation becomes:
95 = 24/30 * x - 5/30 * x
combine like terms to get 95 = 19/30 * x
multiply both sides of the equation by 30/19 to get:
30/19 * 95 = 30/19 * 19/30 * x
simplify to get:
30/19 * 95 = x
solve for x to get x = 150.
the volume of the glass is 150 cubic centimeters.
1/6 * 150 = 25
4/5 * 150 = 120
the difference between 4/5 full and 1/6 full is 95 cubic centimeters.
solution is that the volume of the glass is 150 cubic centimeters.

describe how you would graph 2x+3y=6
Answer:
First get y by itself. (y=-2/3x +2). The y-intercept is at 2 and the slope is -2/3 so starting at (0,2) you would go down two and right three and continue doing that to create your graph.

(d) a and b were born on the same day;
A. symmetric
B. reflexive
C. transitive
D. antisymmetric
E. irreflexive
Answer:
a) Options A, B & D.
b) Options C & D.
c) Options C, D & E
d) Options A, B & C
Step-by-step explanation:
a) Options A, B & D.
- It's irreflexive because b is not older than a.
- It's transitive because if a is older than b as we are told and b is older than c, then we can say that a is older than c.
- It's antisymmetric because if a is older than b, then we can say that b is not older than a.
b) Options C & D.
- It's symmetric because if a & b have a common grandparent, then we can say that b and a have a common grandparent.
- It's reflexive because a and b have common grandparents and thus implies all of a's grandparents.
c) Options C, D & E are correct.
It could be Transitive, symmetric or antisymmetric.
d) Options A, B & C are correct.
