There is one dot at 3.45. What does that value
represent?
A school administrator claims that the average GPA of
the senior class is 3.53. You think that the average GPA
is greater than that, so you select a random sample of
100 seniors and calculate their average GPA. The
sample mean GPA is 3.70.
Using technology, you simulate selecting 100 SRS of
size n = 100 from a population of seniors for which the
mean GPA is 3.53. This dotplot shows the results.
O In one simulated SRS of 100 students, the average
GPA was = 3.45.
In one simulated SRS of 100 students, the
population mean GPA was u = 3.45.
There is a 1 out of 100 chance that the population
mean GPA is = 3.45.
O A majority of the sample of 100 students had a GPA
of r = 3.45.

Answer:

A

Step-by-step explanation:

Answer:

43.27

Step-by-step explanation:

(24×24)+(36×36)= 1872

√1872=43.27

Using the Pythagorean theorem:

Hypotenuse = sqrt( 24^2 + 36^2)

Hypotenuse = sqrt(576 + 1296)

Hypotenuse = sqrt(1872)

Hypotenuse = 2sqtt(469) or 43.266

Answer: Simple interest amount larger by $9.00

Step-by-step explanation:

Simple interest of 4.1% on $2,750 for 4 years:

Formula for simple interest is:

= Amount * (1 + rate * no. of periods)

= 2,750 * ( 1 + 4.1% * 4)

= 2,750 * 1.164

= $3,201

Compound interest of 3.8% on $2,750 for 4 years:

= Amount * (1 + rate) ^ no. of periods

= 2,750 * ( 1 + 3.8%)⁴

= $‭3,192

Difference:

= 3,201 - 3,192

= $9.00

Answer:

28

Step-by-step explanation:

Answer:

46

Step-by-step explanation:

Given

a³ - 2bc + 5ac ← substitute values for a, b, c into the expression

= 3³ - (2 × - 2 × 1) + (5 × 3 × 1)

= 27 - (- 4) + 15

= 27 + 4 + 15

= 46

Answer:

Step-by-step explanation:

Refer to your previous question:

Radius of the inscribed circle is the apothem of the hexagon.

Apothem (a) and half of the side (s) make a 30-60-90 right triangle.

The ratio of the legs, as per property of 30-60-90 triangle:

Half the side is s = 10 units, then side of the hexagon is 20 units.

The area of the hexagon:

Answer:

degree of the polynomial = 7

Number of terms = 2

Name = binomial

leading coefficient = 5

Step-by-step explanation:

The polynomial is x³y² - 5x³yz³

The degree of a polynomial is the highest exponent of any of its variables.

But in this case where we have two variable together, we sum up their exponents and the Hughes one will be the degree of the polynomial.

Thus;

x³y² has a degree of 3 + 2 = 5

5x³yz³ has a degree of 3 + 1 + 3 = 7

Thus,7 is the highest and the degree of the polynomial is 7.

There are two terms which are x³y² and 5x³yz³

Since it has two terms, it is a binomial.

To get the coefficient, I will rearrange in descending order of degree;

-5x³yz³ + x³y²

Thus, leading coefficient = 5

Answer:

[tex]34[/tex]

Step-by-step explanation:

Let the first number be [tex]x[/tex]

The next number be [tex]2[/tex] more than the previous as it is an even number

The second number is [tex]x+2[/tex]

and the last number is [tex]x+4[/tex]

The sum of the numbers is [tex]108[/tex], so the expression will be

[tex]x+(x+2)+(x+4)=108[/tex]

[tex]\Rightarrow 3x+6=108[/tex]

[tex]\Rightarrow x=\dfrac{108-6}{3}[/tex]

[tex]\Rightarrow x=34[/tex]

The smallest of the three numbers is [tex]34[/tex].

Answer:

Step-by-step explanation:

Answer:

3x-2 = -x+10

or, 3x+x=10+2

or, 4x=12

or, x=12/4

So, x=3

Answer: 3

Step-by-step explanation:

Step 1: Add x to both sides.

3x−2+x=−x+10+x

4x−2=10

Step 2: Add 2 to both sides.

4x−2+2=10+2

4x=12

Step 3: Divide both sides by 4.

4x

Answer:

m = 0.75well 1.7 bc 5.35/3=1.7 This is the cost per pound of the mints.

Step-by-step explanation:

From this sentence >> 3 pounds of candy and 2 pounds of mints cost $10.80

you can make-up an equation >> 3c + 2m = 10.80 right?

That's your first equation, 3c + 2m = 10.80 ... (1)

and from this sentence >> 1 pound of candy and 3 pounds of mints cost $5.35

you can make-up an equation >> c + 3m = 5.35 ... (2)

you can use various methods here, like graphing, substitution, comparison, and elimination method.

Let's try using substitution method.

3c + 2m = 10.80 ... (1)

c + 3m = 5.35 ... (2) << here you can come up with c = 5.35 - 3m then substitute it to (1)

3c + 2m = 10.80 ... (1)

3(5.35 - 3m) + 2m = 10.80

16.05 - 9m + 2m = 10.80

-7m = -5.25

m = 0.75 <<This is the price of the mint

to get the price of candy, simply substitute m = 0.75 to (1) or (2) if you want, it depends on you.

Either way, you will have the same answer.

Let's try substituting in (1)

3c + 2m = 10.80 ... (1)

3c + 2(0.75) = 10.80

3c + 1.5 = 10.80

3c = 9.3

c = 3.1 <<this is the price of the candy

Step-by-step explanation:

4 triangles bh/2=area

2 x 2/2 = 2

2 x 4triangles = 8 units

two rectangles bh=area

2 x 6 = 12

12 x 2rectangles = 24 units

last rectangle is bh

6 x 8 = 48 untis

24+48+8=80 units
