Standard Celebration Chart is used by precision teachers to track rate of learning and ensure the learner is on track for attaining fluency.

Since , It is a consistent display of frequency of change over time (celebration) precision teachers use it to track rate of learning and ensure the learner is on track for attaining fluency. The Standard Celebration Chart (initially called the Standard Behavior Chart) is used to observe and improve human learning and interaction. The chart shows the frequency of performance and its celebration, i.e., growth of learning across time.

Frequency, whose formula is

F = Count/Time,

Tells what happened during a specific time.

Celebration, whose formula is

C = Count/Time/Time, or Frequency/Time, tells what happens across the longer period of time – weeks, months, years, or decades.

All Standard Celebration Charts retain and present the original data in the form of frequency and celebration.

Answer:

144 seconds

Step-by-step explanation:

divide 90 by 15 to get 6

if you are jumping in sets of 15, that means you need to jump 6 sets to get to a total of 90 jumps total. if every set of 15 jumps takes 24 seconds that means that 6 sets will take 144 seconds. 6 x 24 = 144

Answer:

Step-by-step explanation:

Let x and (x + 1) be the page numbers Josiah can see

Hint 1: x(x + 1) = 930

⇒ x² + x = 930

⇒ x² + x - 930 = 0

Using quadratic formula,

\(x = \frac{-b\pm\sqrt{b^2 -4ac} }{2a}\)

a = 1, b = 1 and c = -930

\(x = \frac{-1\pm\sqrt{1^2 -4(1)(-930)} }{2(1)}\\\\= \frac{-1\pm\sqrt{1 +3720} }{2}\\\\= \frac{-1\pm\sqrt{3721} }{2}\\\\= \frac{-1\pm61 }{2}\\\)

\(x = \frac{-1-61 }{2}\;\;\;\;or\;\;\;\;x= \frac{-1+61 }{2}\\\\\implies x = \frac{-62 }{2}\;\;\;\;or\;\;\;\;x= \frac{60 }{2}\\\\\implies x = -31\;\;\;\;or\;\;\;\;x= 30\)

Sice x is a page number, it cannot be negative

⇒ x = 30 and

x + 1 = 31

No, because you gave T a Boolean when T expected a student as its first argument and a course as its second parameter. This will be less formal if.

The expected,

T(‘‘user2012813",‘‘discrete math")=true

However, the function F(x) and A both yield either true or false (y). Thus, you are attempting to assess

T(F(‘‘user2012813"),A(‘‘discrete math"))=T(true, false)= NULL

Only the first formulation makes sense, but after relations are established, these kinds of structures can be used.

Null functions as both a value and a pointer in computer programming. A built-in constant called null has a value of zero. It is the same as how strings in C are terminated with the letter 0.

Null is another possible value for a pointer, and unless the CPU supports a unique bit pattern for a null pointer, it has the same value as zero.

The 95% confidence interval for the proportion of residents victimized by a criminal is approximately 0.275 to 0.419. The lower limit is 0.275, and the upper limit is 0.419.

To construct a 95% confidence interval for the proportion of all residents in the city who have been victimized by a criminal, we can use the formula for the confidence interval of a proportion:

Lower limit = sample proportion - margin of error

Upper limit = sample proportion + margin of error

First, we calculate the sample proportion:

sample proportion = number of respondents who reported being victimized / total sample size

sample proportion = 52/150 = 0.347

Next, we calculate the margin of error:

margin of error = critical value * standard error

The critical value for a 95% confidence interval is approximately 1.96 (obtained from a standard normal distribution table).

To calculate the standard error:

standard error = square root of [(sample proportion * (1 - sample proportion)) / sample size]

standard error = √[(0.347 * (1 - 0.347)) / 150] ≈ 0.037

Now, we can calculate the margin of error:

margin of error = 1.96 * 0.037 ≈ 0.072

Finally, we can construct the confidence interval:

Lower limit = 0.347 - 0.072 ≈ 0.275

Upper limit = 0.347 + 0.072 ≈ 0.419

Therefore, the 95% confidence interval for the proportion of residents victimized by a criminal is approximately 0.275 to 0.419. The lower limit is 0.275, and the upper limit is 0.419.

Answer:5.68x10^5

Step-by-step explanation:

Answer:

He should pay $2,790.7.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

\(E = P*I*t\)

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time, in years.

After t years, the total amount of money is:

\(T = E + P\)

In this question:

Rate of 10%, so I = 0.1.

9 months, so \(t = \frac{9}{12} = 0.75\)

How much should he pay for a note that will be worth $3,000 in 9 months?

We have to find P for which T = 3000. So

\(T = E + P\)

\(3000 = E + P\)

\(E = 3000 - P\)

Then

\(E = P*I*t\)

\(3000 - P = P*0.1*0.75\)

\(1.075P = 3000\)

\(P = \frac{3000}{1.075}\)

\(P = 2790.7\)

He should pay $2,790.7.

The values of the constants m and c include the following:

m = -1.3

c = 7.1

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;

y = mx + c

Where:

Since the point P(-7, 2) is mapped onto P' (3, -11) by the reflection y = mx + c, we can write the following system of equations;

2 = -7m + c    ...equation 1.

-11 = 3m + c    ...equation 2.

By solving the system of equations simultaneously, we have:

2 = -7m - 3m - 11

11 + 2 = -10m

13 = -10m

m = -1.3

c = 7m + 2

c = 7(-1.3) + 2

c = -7.1

Answer:

The proportion of these light bulbs that will last less than the advertised time is 18.94% or 0.1894

Step-by-step explanation:

The first thing to do here is to calculate the z-score

Mathematically;

z-score = (x - mean)/SD

= (1500-1550)/57 = -50/57 = -0.88

So the proportion we will need to find is;

P( z < -0.88)

We shall use the standard score table for this and our answer from the table is 0.1894 which is same as 18.94%

Step-by-step explanation:

Hi there!

Combine Like Terms:

5m-4=m+m+4+4

5m-4=2m+8

Now, move all the numbers to the right, using the opposite operation:

5m=2m+8+4

5m=2m+12

Now, move 2m to the left:

5m-2m=12

3m=12

Divide both sides by 3:

m=4

5m - 4 = m + 8 + m

Combine like terms: 5m - 4 = m + 8 + m

5m - 4 = 2m + 8

Add 4 to both sides of the equation: 5m - 4 = 2m + 8

5m- 4 + 4 = 2m + 8 + 4

Number of bad guys = 12

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given,

Ratio of good to bad guys = 15:4 = 15/4

No. of good guys = 75

Let the no. of guys be x

⇒ 15:4 = 75:x

⇒ 15/4 = 75/x

Cross multiplying

15 x = 75×4

x = (75/15)×4

No. of bad guys = (75/15)×4

                           = 3 × 4

No. of bad guys = 12

The response we have is as follows to the query that was asked the store owner's profit is 27.7 percentage of the selling price of grapes.

A percentage is a ratio or figure expressed as a portion of 100 in mathematics. Additionally, the abbreviations "pct.," "pct," and "pc" are rarely used. However, it is frequently denoted by the percentage sign "%". The percentage number has no dimensions. Basically, when the number is 100, percentages are fractions. A figure should be followed by the percent sign (%) to show that it is a number. For instance, if you correctly answer 75 out of twenty-five pages (75/100) on a test, you receive a 75% grade. When converting amounts to percentages, multiply the outcome by 100 after splitting by the sum. (Value/Total) is multiplied by 100% to get the proportion.

Profit = Selling Price - Cost Price

In this case, the cost price of 1 pound of grapes is $1.80 and the selling price is $2.49. Therefore,

Profit = $2.49 - $1.80 = $0.69

Profit Percentage = (Profit / Selling Price) x 100%

= ($0.69 / $2.49) x 100%

= 27.7%

Therefore, the store owner's profit is 27.7% of the selling price of grapes.

Answer:

4,050 cubic feet

Step-by-step explanation:

The figure is made up of a square pyramid and cube

Therefore:

Volume of the figure = volume of the square pyramid + volume of the cube

✔️Volume of the square pyramid = ⅓*a²h

a = 15 ft

h = 9 ft

Volume of square pyramid = ⅓*15²*9 = 675 ft³

✔️Volume of the cube = s³

s = 15 ft

Volume of the cube = 15³ = 3,375 ft³

✔️Volume of the figure = 675 + 3,375 = 4,050 cubic feet
