The equation of the graphed parabola is y=a\((x+3)^{2}\)-4.

Given that parabola is plotted, concave up , with vertex located at coordinates (-3,-4).

We are required to find the equation of the graphed parabola.

The equation of a quadratic function of vertex (h,k) is given by:

y=a\((x-h)^{2}\)+k

In the above equation a is the leading coefficient.

We have been given point (-3,-4).

We have to just put the value of h=-3 and k=-4 and the required equation will be as under:

y=a\((x+3)^{2}\)-4

Hence the equation of the parabola which is plotted, concave up, with vertex located at coordinates (-3,-4) is y=a\((x+3)^{2}\)-4.

Due to its smaller range than Group A, Group B has a lower overall variability and a higher median than Group A.

Probability refers to the likelihood that an event will occur.

In real life, we frequently have to make predictions about the future.

We might or might not be aware of how an event will turn out.

When this occurs, we proclaim that there is a possibility that the event will occur.

In conclusion, probability has a wide range of amazing uses in both business and this rapidly developing area of artificial intelligence.

The chance of an event can be calculated using the probability formula by simply dividing the favorable number of possibilities by the total number of outcomes.

According to our question-

The median is the line in the center of the box, and as you can see from the number line, b's median is higher.

Because the outliers are the small marks at the end and b's marks are closer together, the entire line of b is then shorter and has less variability.

Answer:

The answer is below

Step-by-step explanation:

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by the formula:

\(z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mean,\ \sigma=standard\ deviation.\\\\For \ a\ sample\ size(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }\)

Therefore given that μ = $85900, σ = $11000, n = 35.

For x > 70000:

\(z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{70000-85900}{11000/\sqrt{35} } =-8.55\\\)

For x < 100000

\(z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{100000-85900}{11000/\sqrt{35} } =7.58\)

From the normal distribution table, P(70000< x < 100000) = P(-8.55 < z < 7.58) = P(z < 7.58) - P(z < -8.55) = 1 - 0 = 1 = 100%

Answer:

(b) \(\$24,169.60\)

Step-by-step explanation:

Given:  Cost of car is \(\$22,346.16\)

            Sales tax is \(7.6\%\)    

             The license and title  charges are \(\$125.13\)

To find: The amount that the credit union will finance.

Solution:

We have,  

Cost of car\(=\$22,346.16\)  

Sales tax is \(7.6\%\) of \(\$22,346.16\)

Therefore,  

sales tax \(=\frac{7.6}{100}\times22,346.16=\$1698.31\)

The license and title  charges \(=\$125.13\)

Now, the amount that the credit union will finance is

cost of car\(+\)sales tax\(+\)the license and title  charges

\(=\$22346.16+\$1698.31+\$125.13\)

\(=\$24,169.60\)

Hence, the amount that the credit union will finance is \(\$24,169.60\).

So, (b) \(\$24,169.60\) is correct.

If x is the point reached by F after t seconds, and y is the point reached by S after t seconds, then x = 3t, y = 2t. 30 seconds after leaving point 0, 30 units far apart are F and S. At 100 seconds, F and S will be 100 units apart.

The speed of F reached 12 units in 4 seconds or 3 units per second.

 x = 3t

The speed of S reached 8 units in 4 seconds or 2 units per second.

 y = 2t

x - y = 3t -2t = t

After 30 seconds, the bugs will be apart by (x -y) = 30 units

Therefore, we cannot determine the percentage of guests who ordered coffee from the information provided in either statement alone.

Percent is a way of expressing a quantity as a fraction or a ratio of 100. The word "percent" means "per hundred." It is denoted by the symbol % and is used to describe a portion or a fraction of a whole, where 100% represents the whole. For example, if 40 out of 100 students in a class passed an exam, we can say that 40% of the students passed. Percentages are commonly used in everyday life, finance, and mathematics to represent changes, discounts, taxes, and interest rates.

Here,

Using the information provided in the statements:

(1) If 60 percent of the guests who ordered dessert also ordered coffee, we can determine that 60 percent of the 75 percent who ordered dessert also ordered coffee. That means that 0.60 x 0.75 = 0.45, or 45 percent of the guests ordered both dessert and coffee. However, this information alone does not tell us how many guests ordered coffee in total, as some guests who did not order dessert could have still ordered coffee.

(2) If 90 percent of the guests who ordered coffee also ordered dessert, we can determine that 90 percent of the guests who ordered coffee ordered dessert. However, we cannot determine how many guests in total ordered coffee, as some guests who did not order dessert may have still ordered coffee.

Answer:

40

Step-by-step explanation:

let the number be 'x'

95 % of x = 38

(95 / 100)x =38

x = 38 × 100 / 95

x = 2 × 100 / 5

x = 2 × 20

Answer:

The maximum velocity of a body of mass 200g performing in Simple Harmonic Motion (SHM) at a frequency of 50Hz at a distance of 100cm from the main position is 2000m/s. This can be calculated using the equation: velocity = (2π x frequency) x amplitude, where frequency is 50Hz, amplitude is 100cm, and 2π is equal to 6.28. Thus, the maximum velocity is (6.28 x 50) x 100 = 3140m/s.

The 20th prize is $4400.

It is a sequence where the difference between each consecutive terms is the same.

Example:

2, 4, 6, 8 is an arithmetic sequence.

We have,

First prize = $12,000

Successive prize worth $400 less than the preceding prize.

Now,

We can make an arithmetic sequence.

12,000, 11,600, 11,200, ...

So,

a = 12,000

d = -400

The nth term of an arithmetic sequence.

= a + (n - 1)d

So,

The 20th prize.

= 12,000 + (20 -1)400

= 12,000 - 19 x 400

= 12,000 - 7600

= 4400

Thus,

since 1 half gallon needs 1 salt pckt

11 half gallons will need 11 packets

Answer:

11 salt packets

Step-by-step explanation:

For each half gallon you need one salt packet. So if you have 5 and a half gallons, you need 11 salt packets.

well, we know there are 60 minutes in 1 degree, so 24' is 24/60 = 0.4°, so 61°24' is really 61.4°,  now, we also know that there are 180° in π radians, so

\(\begin{array}{ccll} degrees&radians\\ \cline{1-2} 180&\pi \\ 61.4&x \end{array}\implies \cfrac{180}{61.4}~~ = ~~\cfrac{\pi }{x} \\\\\\ 180x=61.4\pi \implies x=\cfrac{61.4\pi }{180}\implies x=\cfrac{307\pi }{900}\implies x\approx 1.07~radians\)

So the next time they will leave together is 4:24 pm

Step-by-step explanation:

Since both the buses left at 4 pm and red line bus leaves every 6minutes and blue line bus leaves every 8 minutes they next time they leave together can be found by taking the L.C. M of 6 and 8.

The L.C. M is found by multiplying all the factors and chosing one which common in both numbers.

Factors of 6 = 2*3

Factors of 8= 2*2*2

In these numbers 2 is common in both.The rest of the numbers( 2*2*3 )are multiplied with the the common 2 to get the L.C.M

L.C.M= 2*2*2*3= 24 minutes

So the next time they will leave together is 4:24 pm

The required equation in slope intercept form is given by y = 8x + 36.

In the equation intercept is the value of the linear function where either of the variables is zero.

Here,
Points are (-4,6) and (-5,-2)

The slope of the line is given as,

M = (y₂ - y₁) / (x₂ - x₁)

m = -2 - 6 / -5 + 4
m = -8/-1
m = 8

Now,
The Equaiton of the line is given as,
y - y₁ = m (x - x₁)
y - 6 = 8 (x + 4)
y = 8x + 32 + 6
y = 8x + 36

Thus, the required equation in slope intercept form is given by y = 8x + 36.
