Choose the inequality represented in the graph.

A. y ≥ -4/5x - 3
B. y > -5/4x - 4
C. y > -4/5x - 3
D. y < -5/4x - 3

Answers

Answer:

C

Step-by-step explanation:

The line is dotted, so the sign is non-inclusive.

The dotted line is y = -(4/5)x - 3.

The section of the graph above the line is shaded so this inequality is "greater than".

So, putting these together, you get:

C. y > -(4/5)x - 3

Mr. Marsh plans to tile the floor in his 6-foot by 8-foot front hall. If each tile is an 8-inch square. what is the minimum number of tiles needed to cover the floor?

Answers

The division is one of the four fundamental arithmetic operations. The number of tiles that will be needed to cover the entire area of the hall is 864.

What is Division?

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

The area of the hall with dimensions 6 feet by 8 feet are:

[tex]\rm \text{Area of the hall} = 6 feet \times 8foot =48\ feet^2[/tex]

The area of the tile is 8 square inches, therefore, the area of tile in square feet can be written as,

[tex]\rm \text{Area of the tile} = \dfrac8{12 \times 12}\ feet^2[/tex]

Noe, the number of tiles needed to tile the complete area of the hall is,

[tex]\text{Number of tiles needed} = \dfrac{\text{Area of the hall}}{\text{Area of the tile}}\\\\\\\text{Number of tiles needed} = \dfrac{48}{\frac8{12 \times 12}} = \dfrac{48 \times 12 \times 12}{8} = 864[/tex]

Hence, the number of tiles that will be needed to cover the entire area of the hall is 864.

Find the arc length of the semicircle.
Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi and enter your answer as a decimal.

Answers

Answer:

18.852

Step-by-step explanation:

Formula to find the arc of semi circle is :

Arc length = π r

Given that,

diameter ⇒ 12

So, the radius will be,

Radius ⇒ 12 / 2

            ⇒ 6

Let us solve now.

Arc length = π r

                  = 3.142 × 6

                  = 18. 852

If P is the incenter of triangle JKL, find PJ

Answers

If P is the incenter of ΔJKL, then we have,
PN = PM = PO


To find PJ first we need to calculate the value of x
Since,

PN = 22
So,
PM = 22

Now, in ΔPJM we have,

PJ^2 = PM^2 + MJ^2
PJ^2= (22)^2 +(2x+3)^2...(1)

Also, In ΔPJO we have,

PJ^2 = PO^2 + OJ^2
PJ^2 = (22)^2 (5x - 45)^2...(2)

From equation (1) and (2) we obtain,

(5x - 45)^2+(22)^2=(2x+3)^2 +(22)^2
25x^2 — 450x + 2025 = 4x^2 + 12x + 9
25x^2 — 4x^2— 450x — 12x + 2025 — 9 = 0
21x^2 — 462x + 2016 = 0
x^2 - 22x+96 = 0
x^2 — 16x — 6x + 96 = 0
x(x - 16) -6(x - 16) = 0
(x - 6)(x - 16) = 0
Either x=6 or x=16

At x = 6
JO = 5 x 6 - 45
= 30 - 45
= -15

Which cannot be possible because edge length cannot be negative
So the value of x = 16

Hence, the length of PJ is

PJ^2 = 484 + (80 - 45)^2
PJ^2 = 484 + 1225
PJ^2 = 1709
PJ = √1709
PJ = 41.33

Therefore, the length of PJ is 41.3 units

Using the Empirical Rule, it is found that the correct statements are given by:

About 16% of all exam scores are less than 86.5 points.About 16% of all exam scores are greater than 89.5 points.About 84% of all exam scores are less than 89.5 points.

What does the Empirical Rule state?

It states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of  the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.

We also have to consider that the normal distribution is symmetric. Then, alog with the mean of 88 and standard deviation of 1.5, the correct statements are given by:

About 16% of all exam scores are less than 86.5 points(more than 1 standard deviation below the mean, the percentage, considering the symmetry, is 0.5 x 32 = 16%).About 16% of all exam scores are greater than 89.5 points, due to the same explanation as above.About 84% of all exam scores are less than 89.5 points, as the percentage is 50%(all below the mean) + 50% x 68%(one standard deviation above the mean) = 84%.

A person with type O blood can donate red blood cells to anybody because type O blood is the universal blood type. About 44% of the US population has type O blood. University High held a blood drive where 50 students donated blood.

Part A: What is the probability that exactly 25 of the students had type O blood?

Part B: What is the probability that at least 25 of the students had type O blood?

Answers

Answer:

Part A.

k= 25

p= 44% = 0.44

n= 50

P(x = k) = (nk) p^k (1 - p) ^n - k

P(x = 25) = (50 25) (0.44)^25 (1 - 0.44) ^50 - 25

50!/25!(50 - 25)!

50!/25!(25)! = 1.264106 x 1014

P(x=25) = (1.264106 x 1014)(0.44)^25(0.56)^25

= 0.07812

= 7.8% probability that exactly 25 students have type O blood

Part B.

Do the same math you did above. Just replace 25 with 26 and 27 :)

25 = 7.8% probability

26 = 0.01851

 = 1.8% probability

27 = 0.00405

 = 0.4% probability

Step-by-step explanation:

Use the distributive property to distribute 5 to x and -20

5x - 100

2. Expand [tex]\frac{1}{2} (4x + 4)[/tex]:

Use the distributive property to distribute [tex]\frac{1}{2}[/tex] to 4x and 4

2x + 2

3. Add 100 to both sides:

5x - 100 = 2x + 2

5x - 100+100 = 2x + 2+100

5x = 2x + 102

4. Subtract 2x from both sides:

3x = 102

5. Divide both sides by 3:

x = 34

b. What is the area of the pizza?
c. If you cut the pizza into 8 congruent slices, what is the area of one slice?
d. What is the length of the crust of one slice?

Answers

Step-by-step explanation:

pizza = circle

the area of a circle is

pi×r²

r = radius (half of the diameter). in our case 20/2 = 10".

the circumference of a circle is

2×pi×r

again, r = radius.

in our case that gives us

a.

2×pi×r = 2×pi×10 = 20×pi = 62.83185307... "

b.

the area of the pizza is

pi×10² = 100×pi = 314.1592654... in²

c.

it is 1/8 of the whole area, of course.

314.1592654... / 8 = 39.26990817... in²

d.

it is 1/8 if the whole circumference, of course.
