Answer:
$43.40
Step-by-step explanation:
First, you would have to find out how much was discounted. To find this, you multiply $62.00 (the total) by 30% (the discount sale). You will end up getting $18.60. Finally, you can subtract $18.60 from the original total which was $62.00 to get $43.40 after the discount.

A graph of a linear function is shown on the grid. Which of these best represents 0 of the function? A 8. B 10. C 16. D 24.
answer:
C. 16
explanation:
when x is 0, the y-intercept is 8
coordinates: (0,8) and (4,6)
slope:
[tex]\sf \frac{y2-y1}{x2-x1}[/tex]
[tex]\sf \frac{6-8}{4-0}[/tex]
[tex]\sf \frac{-2}{4}[/tex]
[tex]\sf -\frac{1}{2}[/tex]
equation:
[tex]\sf y = mx +b[/tex] [ where m is slope and b is y-intercept ]
[tex]y = \sf -\frac{1}{2}x +8[/tex]
solve for x-intercept:
note: zeros of a function are the values of x when f(x) is equal to 0
[tex]y = \sf -\frac{1}{2}x +8[/tex]
[tex]0= \sf -\frac{1}{2}x +8[/tex]
[tex]-8= \sf -\frac{1}{2}x[/tex]
[tex]\sf x = -8 * -2[/tex]

If A and B are dependent events, which of these conditions must be true? A. P(A and B) = P(A) P(B) B. P(A and B) = P(B) P(A) C. P(B|A) = P(B) D. P(A|B) = P(A) E. P(B|A) P(B).
The true condition about the dependent events, P(B|A) is not equal to P(B).
What is dependent probability?Dependent events in probability mean events whose occurrence of one affect the probability of occurrence of the other.
Two events are said to be dependent if the outcome or occurrence of the first affects the outcome or occurrence of the second so that the probability is changed.
Also, Two events are said to be independent if the outcome or occurrence of the first does not affect the outcome or occurrence of the second so that the probability is not changed.
For independent events: P(A and B) = P(A) x P(B).
Recall that P(B|A) = P(A and B) / P(A) = P(A) x P(B) / P(A) = P(B).
Therefore, for dependent events, P(B|A) is not equal to P(B).

If sin 64° = p, determine the value of the following in terms of p.
8 sin 16º.cos 16º.cos32°
We are provided that [tex]{\sf \sin (64^{\circ})=p}[/tex] and we have to find the value of [tex]{\sf 8\sin (16^{\circ})\cdot \cos (16^{\circ})\cdot \cos (32^{\circ})}[/tex] . But let's recall a identity which is gonna be very helpful to do this question i.e
[tex]{\boxed{\sf 2\sin (\theta)\cos (\theta)=\sin (2\theta)}}[/tex]Now , coming back on the question ;
[tex]{:\implies \quad \sf 8\sin (16^{\circ})\cdot \cos (16^{\circ})\cdot \cos (32^{\circ})}[/tex]
[tex]{:\implies \quad \sf 4\{ 2\sin (16^{\circ})\cos (16^{\circ})\}\cos (32^{\circ})}[/tex]
Using the above identity ;
[tex]{:\implies \quad \sf 4\sin (32^{\circ})\cos (32^{\circ})}[/tex]
[tex]{:\implies \quad \sf 2\{2\sin (32^{\circ})\cos (32^{\circ})\}}[/tex]
Again using the same identity ;
[tex]{:\implies \quad \sf 2\sin (64^{\circ})}[/tex]
Putting the given value of [tex]{\sf \sin (64^{\circ})}[/tex]
[tex]{:\implies \quad \sf 2p}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{8\sin (16^{\circ})\cdot \cos (16^{\circ})\cdot \cos (32^{\circ})=2p}}}[/tex]
Proof of the above identity :-
We know that ;
[tex]{\quad \boxed{\sf \sin (A\pm B)=\sin (A)\cos (B)\pm \cos (A)\sin (B)}}[/tex]
So ;
[tex]{:\implies \quad \sf \sin (A+ B)=\sin (A)\cos (B)+\cos (A)\sin (B)}[/tex]
Putting [tex]{\sf A=B=\theta}[/tex] ,
[tex]{:\implies \quad \sf \sin (\theta+ \theta)=\sin (\theta)\cos (\theta)+\cos (\theta)\sin (\theta)}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{\sin (2\theta)=2\sin (\theta)\cos (\theta)}}}[/tex]

1. Ernest calculated the slope of the graph during the uphill climb to be 10. His work is shown below. Determine whether his calculation was correct or incorrect, and then
explain why.
(2 points: 1 for the answer, 1 for the explanation)
Points: (60, 900). (15, 450)
900-450/60-15 = 450/45 = 10
Answer:
answer is correctthe correct formula was used appropriatelyStep-by-step explanation:
The slope of a line on a graph is found using the slope formula:
m = (y2 -y1)/(x2 -x1)
Ernest used (x1, y1) = (15, 450) and (x2, y2) = (60, 900) to fill values into this formula. In doing so, he got ...
m = (900 -450)/(60 -15) = 450/45 = 10
This is an appropriate use of the formula, so gave Ernest the correct answer.

Find the probability of picking a green or orange marble from a bag
containing 5 green, 3 yellow, and 5 orange marbles.
Answer:
76.92%
Step-by-step explanation:
Green: 5
Orange: 5
Yellow: 3
First: 5 + 5 + 3 = 13
Now we need to find the probablility of picking an orange or green marble.
We need to divide the number of green and orange marbles put together by the total, 13.
10/13 = 76.92%
You have a 76.92% chance of picking either a green or orange marble.

What is the 30th term of the linear sequence
-5 -7 -9 -11 -13
Answer:
the 30th term of the given linear sequence is -63.
Step-by-step explanation:
The given sequence is in arithmetic progression whose difference is given by:
-7 - (-5) = d
d = -2
The nth term in the arithmetic progression is given by the formula:
where 'n' is the number of terms, 'a' is the first term, is the nth term, and 'd' is the difference.
Now, substitute the known terms in the above formula.
So, the 30th term of the given linear sequence is -63.
The fourth term of a sequence is 18.
The term – to – term rule is : ‘ Subtract 3 then multiply by 3.’ What is the first term of the sequence?
Answer:
11/3
Step-by-step explanation:
let the 3rd no be x
(x-3)3 = 18
x-3 = 6
x = 9
keep solving the equation and the first term will be 11/3

Find the specified vector 2v - 6w . Given v = 3i - 5j , w = - i + 4j ,
Answer:
Your question is unclear as to which product you're looking for, the dot product or the cross product, so I'll answer for both.
The i and j notations for vectors refer to their coordinates, e.g. a vector that is 2i+3j is one that moves 2 units in the x-direction and 3 units in the y-direction. This can also be notated as (2, 3), and that's the notation I'll be using in this answer to keep things simple.
In order to get either product, we have to do the subtraction in parentheses first:3v - 4w = 3 * (2, -2) - 4 * (0, -2). When multiplying a vector by a scalar number, you just multiply the coordinates by the scalar, so this becomes (6, -6) - (0, -8). Performing this subtraction by subtracting corresponding coordinates, we get 3v - 4w) = (6, 2). Also, 5u = 5 * (-3, 2) = (-15, 10).
Now, the dot product of two vectors is a scalar quantity. The dot product of the two vectors (-15, 10) • (6, 2) is the sum of the products of the corresponding coordinates. This is -15 * 6 + 10 * 2, which is -90 + 20, and that is -70.

Kaylee has 1 red, 3 blue, 2 brown, 1 purple, and 4 pairs of pink flip flops in her closet. Assuming she always replaces them, what is the probability that she will choose a blue pair on Monday and a pink pair on Tuesday? (Compound Probability)
Answer
she has a 3 out of 11 percent chance aka 3/11
Step-by-step explanation:
There is 1 red meaning there is less of a chance to get that one unless she is lucky same goes with purple! She has 2 brown flip flops so there is more of a chance she may get that one, but 4 pairs of pink flip flops meaning she is more likely to pick pink on Tuesday then Monday. but the answer can be 3/7 if I do not count the others flip flops... but hopefully this helps...
A prism with a base area of 8 cm² and a height of 6 cm is dilated by a factor of 54. What is the volume of the dilated prism? Enter your answer, as a decimal, in the box. Cm³.
The volume of the dilated prism is calculated to be considering scale factor for the area as well as the height is 7558272 cm³.
What is the dilation or scale factor?The scale factor in the dilation of a mathematical object determines how much larger or smaller the image will be (compared to the original object).
Given that
The base area of prism = 8 cm²
Height of the prism = 6
Scale factor = 54
So enlarged area =( scale factor )² * previous area = 54²* 8 = 23328 cm²
Enlarged height = 54*6= 324 cm
Enlarged volume = enlarged area* enlarged height = 7558272 cm³
Thus, the volume of the dilated prism is 7558272 cm³.
