The Empirical Rule states that around 95% of the data in a normal distribution falls within two standard deviations of the mean. The mean ACT Math score in this case is 21, the standard deviation is 3, and the range is 15 to 27.

To determine the interval within which about 95% of the students' scores fall, we can use the Empirical Rule. Since two standard deviations encompass about 95% of the data, we multiply the standard deviation by 2 and add/subtract the result from the mean.

For the ACT Math scores:

Mean - 2 * Standard Deviation = 21 - (2 * 3) = 21 - 6 = 15

Mean + 2 * Standard Deviation = 21 + (2 * 3) = 21 + 6 = 27

Therefore, approximately 95% of the students' ACT Math scores would fall within the interval of 15 to 27.

This means that most of the students' scores are expected to be within this range, with fewer scores falling outside of it. It provides a general understanding of the distribution of scores and helps us identify the central range within which a large majority of the students' scores lie.

Answer:

I don't know bc I can't figure it out sry

An equation is formed of two equal expressions. The negative integer stated in the statement is 1.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the negative integer be represented by -a.

Given that the square of a negative integer has the same value as the sum of that integer plus 2. Therefore, the equation can be written as,

(-a)² = -a + 2

a² = -a + 2

a² + a -2 = 0

a² +2a - a -2 = 0

a(a+2) -1(a+2) = 0

(a-1)(a+2) = 0

a = 1, -2

Since a was a negative integer and we have already used the negative sign in the equation, therefore, the value of a is 1.

Hence, the negative integer stated in the statement is 1.

Answer:

t = 6.3

Step-by-step explanation:

t = 13\(\frac{3}{4}\) - 7.45

t = \(\frac{55}{4}\)-7.45

t= 13.75 - 7.45

t = 6.3

Answer:

T would equal 6.3

Step-by-step explanation:

You can start out by converting 13 3/4 to a decimal, which would be 13.75.

Therefore leaving you with this equation:

t + 7.45 = 13.75

Next, you subtract.

t + 7.45 = 13.75

   -7.45    -7.45

---------------------------

Therefore leaving you with your answer of 6.3 or 6 3/10. I hope this helps!  :)

The hypotheses for the test are H₀: σ₁² = σ₂² and H₁: σ₁² ≠ σ₂². This is a two-tailed test to assess if there is a difference in the standard deviations of sound levels between the areas designated as "casualty doors" and operating theaters. The claim being investigated is whether or not there is a difference in the standard deviations.

The hypotheses for the test are:

H₀: σ₁² = σ₂² (There is no difference in the standard deviations of the sound levels between the areas designated as "casualty doors" and operating theaters.)

H₁: σ₁² ≠ σ₂² (There is a difference in the standard deviations of the sound levels between the areas designated as "casualty doors" and operating theaters.)

This hypothesis test is a two-tailed test because the alternative hypothesis is not specifying a direction of difference.

To substantiate the claim that there is a difference in the standard deviations, we will conduct a two-sample F-test at a significance level of 0.10, comparing the variances of the two groups.

We get the number of bananas as 8 and the number of mangoes as 4.

The general equation of a straight line is -

y = mx + c

{m} - slope.

{c} - intercept along the y - axis.

Given is that Chee and her children went into a grocery store and she bought $12 worth of bananas and mangos. Each banana costs $0.50 and each mango costs $2. She bought twice as many bananas as mangos.

We can write the system of equations as -

x = 2y               .....  (1)

(1/2)x + 2y = 12   ..... (2)

We can write equation (2) as -

(1/2) x 2y + 2y = 12

3y = 12

y = 4

then -

x = 8

Therefore, we get the number of bananas as 8 and the number of mangoes as 4.

Option a is the correct answer. The patient's description of vivid dreams is most likely occurring during rapid eye movement (REM) sleep.

During fast eye development (REM) rest, the mind is exceptionally dynamic, yet the muscles are loose, bringing about the trademark quick eye developments that give this stage its name. It is during REM rest that most dreaming happens. These fantasies will generally be clear, close to home, and frequently strange, and can be serious to such an extent that they might awaken the sleeper. Interestingly, during non-REM rest, the mind is less dynamic, and dreams are ordinarily less striking and vital. The way that the patient depicted clear dreams is serious areas of strength for a that they were in REM rest, as opposed to one of the non-REM stages.

The distance, relative to mile marker 45, to the nearest mile when passing mile marker 112 on a straight highway is 67 miles.

When you pass mile marker 112 on a perfectly straight highway between marker 45 and marker 112, the distance covered is 112 - 45 = 67 miles. This means that you have traveled a total of 67 miles from mile marker 45 to mile marker 112.

To determine the distance relative to mile marker 45, we consider the distance remaining from mile marker 112.

Since you have passed mile marker 112, the remaining distance to cover until you reach the nearest mile relative to marker 45 is the difference between 112 and the nearest mile greater than 112.

Let's assume the nearest mile greater than 112 is 113.

Therefore, the remaining distance is 113 - 112 = 1 mile.

In conclusion, when passing mile marker 112 on the straight highway, the distance relative to mile marker 45 to the nearest mile is 67 miles.

Just count the squares like you would normally do to a rectangle and do the area like you would normally do with a rectangle

Answer:

The correct explanation is **A.**

The area of a sector of a circle is derived by determining the fraction of the circle that the sector represents. This fraction is then multiplied by the area of the entire circle.

For example, if a sector of a circle has an angle of 60 degrees, then it represents 1/6 of the circle. The area of the sector is then calculated as follows:

```

Area of sector = (1/6) * Area of circle

```

```

Area of sector = (1/6) * πr²

```

```

Area of sector = (πr²) / 6

```

The other explanations are incorrect.

* Explanation B is incorrect because the number of triangles within a circle is not relevant to the area of a sector.

* Explanation C is incorrect because the number of sector pieces that fit in a circle does not determine the area of a sector.

* Explanation D is incorrect because the number of sections of the sectors that fit in the circle does not determine the area of a sector.

Answer:

300 adult tickets and 700 children's tickets

Step-by-step explanation:

Let the number of adult tickets sold be a and the number of children's tickets sold be c.

a +c= 1000 -----(1)

Total amount collected

= (number of adult ticket)(cost of an adult ticket) +(number of children's tickets)(cost of a children's ticket)

a(8.50) +c(4.50)= 5700

8.5a +4.5c= 5700 -----(2)

From (1):

a= 1000 -c -----(3)

Substitute (3) into (2):

8.5(1000 -c) +4.5c= 5700

Expand:

8500 -8.5c +4.5c= 5700

Simplify:

8500 -4c= 5700

4c= 8500 -5700

4c= 2800

Divide both sides by 4:

c= 2800 ÷4

c= 700

Substitute c= 700 into (3):

a= 1000 -700

a= 300

Thus, 300 adult tickets and 700 children's tickets were sold.

Answer:

200 ft^2

Step-by-step explanation:

The surface area of the pyramid is the sum of the area of the base and the areas of the 4 congruent triangular sides.

SA = LW + 4 * bh/2

SA = 10 ft * 10 ft + 4 * (10 ft)(5 ft)/2

SA = 100 ft^2 + 2(50 ft^2)

SA = 200 ft^2

(P.S. It's impossible to make a pyramid with these dimensions.)

Answer:

\(\boxed{\sf 200 \ feet^2}\)

Step-by-step explanation:

The 3D shape is a square-based pyramid.

The surface area of a square-based pyramid is given as:

\(\sf SA=2 \times (base \ length) \times (slant \ height) + (base \ length)^2\)

Plug in the values.

\(\sf SA=2 \times 10 \times 5 + 10^2\)

\(\sf SA=100 + 100\)

\(\sf SA=200\)
