$140 was the original price.

discount : 45%

45% ⇒ $63

1% ⇒ $(63/45)

1% ⇒ $1.4

original price is always 100%

100% ⇒ $(1.4*100)

100% ⇒ $140

Let the original price of the necklace be ,'x',

then,

According to the question,

Hence ,the necklace she bought worths $140 without the discount given to her.

The value of b is 4 and the function becomes y = 2x²-12x+8 because (2, -8) lie on the function.

It is defined as the graph of a quadratic function that has something bowl-shaped.

We have:

[tex]\rm y = 2x^2+bx+8[/tex]

The above function shows the equation of the parabola.

From the graph, we can see the point(2, -8) lie on the graph of the function,

So point(2, -8) will satisfy the function.

Plug y = -8 and x = 2 in the function.

[tex]\rm -8 = 2(2)^2+b(2)+8\\\\-16 = 8+2b\\-24 = 2b \\b = -12[/tex]

Thus, the value of b is 4 and the function becomes y = 2x²-12x+8 because (2, -8) lie on the function.

Answer:

D. 36

Step-by-step explanation:

Ratios are a way to represent of how much there is one thing to another. It's a more simplistic representation.

For example, if there were 625 adults and 375 children, we don't say there are 625 adults to 375 children, we say there are 5 adults to 3 children.

All I did was divide both the number of children and adults by 125 and we have a ratio of 5:3 for adults to children respectively.

In this problem, we have a ratio of 3:2 for girls to boys. This 3:2 ratio is a simplistic representation of the number of girls to boys. We know that there are 24 boys.

Dividing 24/2 = 12

12 is the proportion which we multiply by the ratio to get the true numbers for boys and girls.

2 * 12 = 24 boys

3 * 12 = 36 girls

So there are 36 girls in the marching band.

The residual value is the difference in the value of the y coordinate between the real value and the expected value. The residual value will be equal to -0.86.

The residual value is the difference in the value of y coordinate between the real value and the expected value.

Residual Value =  Real value of y - The predicted value of y

The value of y in the table is -2 when the value of x is 5. And as per the function, the value of y when the value of x is 5 can be written as,

[tex]y = -0.7x+2.36\\\\y = -0.7(5)+2.36\\\\y= -3.5+2.36\\\\y=-1.14[/tex]

Now, the residual value can be written as,

[tex]\text{Residual Value} = \text{(Value of y in the table)} - \text{(Value of y as per the function)}\\\\\text{Residual value} = -2 - (-1.14)\\\\\text{Residual value} = -2+1.14\\\\\text{Residual value} = -0.86[/tex]

Hence, the residual value will be equal to -0.86.

Answer:

They'll meet after 200 meters , if they simultaneously start running towards each other.

Step-by-step explanation:

Let x =distance travelled by dog and 200-x be the distance travelled by cat. Inorder to meet, the sum of their travelled distances shall be equal to 200 meters as they are far apart by 200 meters.

Dog: Distance =Speed x time: x=30t

Cat: Distance = 200-x

=24t

The sum of their distance travelled shall be 200 meters: 30t+ 24t= 200;54t=200;t=200/54=3.7secs

So they will meet after 3.7 seconds

To check:

Distance travelled by dog :x=30(3.7)

=111.11 meters

Distance travelled by cat: 24t=24(3.7)

=88.89 meters

Therefore since they are travelling towards each other and their distance apart is 200 meters, after 3.7 seconds they will meet because dog travelled 111.11 meters and cat travelled 88.89 meters and they covered already 200 meters as the sum of 111.11+ 88.89

=200 meters

The equation of the parabola opening upward with a focus at and a directrix will be f(x) = 1/32(x + 9)^2 + 19. so option B is correct.

The equation can be written as

f(x) = 1/(4p)(x -h)^2 +(k-p)

where (h, k) is the focus, and p is half the distance between focus and directrix.

Here, We have the upward parabola;

(h, k) = (-9, 7) and p = (7 - (-9))/ 2 = 8.

So the equation is

f(x) = 1/32(x + 9)^2 + 19

The equation of the parabola opening upward with a focus at and a directrix will be f(x) = 1/32(x + 9)^2 + 19. so option B is correct.

The probability of getting exactly 1 head when a fair coin is tossed 9 times is approximately 0.017, to the nearest thousandth.

To find the probability of getting exactly 1 head when a fair coin is tossed 9 times, we can use the concept of binomial probability. The probability of getting a head on a single coin toss is 1/2, and the probability of getting a tail is also 1/2.

In this case, we want to calculate the probability of getting exactly 1 head out of 9 tosses. This can be represented as a binomial probability with parameters n (number of trials) and p (probability of success).

Using the binomial probability formula:

P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)

where n is the number of trials, k is the number of successful outcomes, and p is the probability of success.

In our case, n = 9, k = 1, and p = 1/2.

Plugging these values into the formula:

P(X = 1) = (9 choose 1) * (1/2)^1 * (1 - 1/2)^(9 - 1)

P(X = 1) = 9 * (1/2) * (1/2)^8

P(X = 1) = 9 * (1/2)^9

P(X = 1) = 9/2^9

P(X = 1) ≈ 0.017

Therefore, the probability of getting exactly 1 head when a fair coin is tossed 9 times is approximately 0.017, to the nearest thousandth.
