Which graph shows y=3⌈x⌉+1?

Answer:

Points shouldn't be connected by straight lines but rather a curve

Step-by-step explanation:

None of the points seem to be incorrect, and the x and y-axis are labeled correctly as well as the points, the only issue I would say there is, is that this is a quadratic equation, so Brogan shouldn't be drawing straight lines between points, but rather a curve.

Using the latest observation in a sequence of data to forecast the next period is a naïve forecast. Option C

What is a  naïve forecast?

A naïve forecast is a forecasting technique in which the last sequence of data are used for the next period's forecast without predictions or adjusting the factors that could affect it.

Forecasts that are  produced using a naïve approach are equivalent to the final observed value gotten.

Thus, using the latest observation in a sequence of data to forecast the next period is a naïve forecast

Answer:

87 grade

Step-by-step explanation:

if yo add a 10% overall grade to you 79.43 you will get an 87.373

79.43 x 10% = 7.943 (points added bc of your 10%added)

79.43 + 7.943 = 87.373

round it and you'll have 87 overall grade

The values of x, EF, and FG from the line segment are 10, 8 and 15 respectively.

An equation is an expression that shows the relationship between two or more numbers and variables.

EG = EF + FG (segment addition postulate)

Hence:

23 = (2x - 12) + (3x - 15)

x = 10

EF = 2(10) - 12 = 8

FG = 3(10) - 15 = 15

Answer:

3 mph

Step-by-step explanation:

So the average speed is simply: [tex]\frac{distance}{time}[/tex]. In case, the total time is 25 minutes + 55 minutes which is a total of 80 minutes, or 1.33 hours. The total distance traveled is two miles + two miles, since he jogged two miles to the park, and then he turns around and walks the same path. So in total he traveled 4 miles. Plugging this in to the formula gives you the equation: [tex]\overline{v}=\frac{4 \text{ miles}}{\frac{4}{3}\text {hours}}=\frac{4\text{ miles}}{1}*\frac{3}{4}\text{ hours} = 3mph[/tex]

The other equality which must be stated by Jose is that angles BAC and BAE are congruent and their measures are equal.

It follows from the task content that Jose is trying to prove the congruence of both triangles by means of the Side-Angle-Side congruence theorem.

It therefore follows that since, Jose has identified that the ratio of corresponding sides are equal as indicated in the task content, the equality which Jose has to state is the angle congruence equality.

Step-by-step explanation:

Answer:

$54.30

Step-by-step explanation:

Given Total Donations already raised

= $30.20 + $10.50 + $5.00

= $45.70

Donations still required = Total Donations needed - Donations already raised

= $100 - $45.70 = $54.30

1/3 of the volunteers can complete the 8-hour workday

Total number of volunteers = 10

If it takes 1 volunteer = 24 hours = 1 day

It would take x number of volunteers = 8 hours

To find 'x' , cross multiply

We have,
x * 24 hours = 8 hours * 1

24x = 8

Make 'x' the subject of formula

x = 8/ 24

x = 1/3

Therefore, 1/3 of the volunteers can complete the 8-hour workday

62 m is the parameter of the given figure.

The perimeter of a two-dimensional form is the space surrounding it. It represents the total length of the shape's sides. The units used to measure the sides of the form, such as meters, centimeters, inches, or feet, determine the units used to measure the perimeter.

In a statistical context, parameters often refer to the unknown values of a probability distribution. In this case, parameters can be estimated using statistical methods such as maximum likelihood estimation or Bayesian inference.

Add all sides, the top is the same as the bottom, (the side of 6 must be counted only once).

By using the definition of second order polynomials and the discriminant from quadratic formula, we conclude that the values of k must be less than 1/4.

In this question we must determine the set of values of k such that the function g(x), a linear function, intersects a quadratic function f(x) at two points. In this case, we must solve the following second order polynomial:

k · x² + 4 · x - 3 - g(x) = 0

k · x² + 4 · x - 3 - 2 · x + 7 = 0

k · x² + 2 · x + 4 = 0

In this case, the discriminant of the equation described above must be positive:

2² - 4 · k · 4 > 0

4 - 16 · k > 0

4 > 16 · k

16 · k < 4

k < 1/4

By using the definition of second order polynomials and the discriminant from quadratic formula, we conclude that the values of k must be less than 1/4.

Answer:

Step-by-step explanation:

Original equation:

[tex]7(2)^x=224[/tex]

Divide both sides by 7

[tex]2^x=32[/tex]

Rewrite in log

[tex]log_232=x[/tex]

You can do mental math to realize this equals 5, or plug this into your calculate (if it allows you to set the base), but if you can't do either, you can use the change of base formula:

[tex]log_ba=\frac{log (a)}{log(b)}[/tex]

You get:

[tex]log_232=\frac{log(32)}{log(2)}[/tex]

When you calculate using a calculator you should get 5

Answer: x = 5

Step-by-step explanation:

[tex]7(2)^x=224[/tex]

start by dividing 7 from both sides

[tex]\frac{7(2)^x}{7} =\frac{224}{7}[/tex]

[tex]2^x=32[/tex]

take the log of both sides

[tex]log(2^x) = log(32)[/tex]

move the x to the left of the log

[tex]xlog(2) = log(32)[/tex]

divide both sides by log(2)

[tex]x=\frac{log(32)}{log(2)}[/tex]

use change-of-base formula

[tex]\frac{log(a)}{log(b)} =logx_{b} (a)[/tex]

[tex]x = log_{2} (32)[/tex]

Answer:

AB = 4

BC = 4

AC = 8

Step-by-step explanation:

Given, B is the midpoint of AC which means it divided the AC into two equal parts. Using this information we can write the following equation:

5x - 6 = 2x add 6 to both sides

5x = 2x + 6 subtract 2x from both sides

3x = 6 divide both sides by 3

x = 2 to find the length of AB, AC, and BC replace x with 2

AB = 5*2 - 6

BC = 2*2

AC = 8 (sum of AB and BC)

Let, just assume a vehicle is given an economy of $280 of 7m.

The ratio can be defined as the comparison of the fraction of one quantity towards others. E.g.- water in milk.

Now,
The ratio can be given as for economy = 280/7
=  $40/m

here for new values,
suppose the vehicle travel for 40miles in 10 mins
ratio = 40/10= 4 miles/min
and vehicle consumes 2 liter fuel on 60 miles of distance ratio can be given as
