A group of 55 pupils were asked if they owned a phone or a tablet.

11 people are known to own both

18 said they only owned a tablet

34 said they owned at least a phone

A student is picked a random, what is the probability that the student doesn’t have a phone or tablet? Give your answer as a fraction in its simplest form.

Select your answer from the list below:

A: 3/63

B: 3/55

C: 11/55

D: 18/55

3/4(2(2+4k)+2(3+3/2k))

Use the distributive property inside the parenthesis first:

3/4(4+8k + 6 + 3k)

Simplify:

3/4(11k + 10)

Distributive property again:

3/4(11k) + 3/4(10)

33/4k + 15/2

Rearrange to get A. 15/2 + 33/4k

5. you would use whole numbers because points are whole

Answer:

5400 cm^3

Step-by-step explanation:

Volume = Base Area * H

Base area is the area of a square with one side = 30 cm

H = 6cm

Base Area = s^2

Base Area = 30^2 = 900

Volume  =  900 * 6

Volume = 5400 cm^3

Answer:

1800 cm³

Step-by-step explanation:

Recall that the formula for the area of a square is A = s², where s is the side length.

Here, that area is A = (30 cm)²2.

The formula for the volume of a square pyramid is:

V = (1/3)(base area)(height)

   = (1/3)(30 cm)²2*(6 cm)

   = (1/3)(900 cm²)(6 cm) = 1800 cm³

The volume of this pyramid is 1800 cm³.

Step-by-step explanation:

Julia ate 1/8

Ellen and Jenny ate 3/8

1/8 + 3/8 = 4/8

No they didn't eat the whole pizza, they only ate half of the pizza.

Julie, Ellen, and Jenny together ate [tex]\frac{1}{8}[/tex]+ [tex]\frac{3}{8}[/tex] = [tex]\frac{4}{8}[/tex] or [tex]\frac{1}{2}[/tex]of the pizza, which means they ate only half of it, not the entire pizza.

The question involves the mathematical concept of fractions and their addition. Julie ate [tex]\frac{1}{8}[/tex] of the pizza, while Ellen and Jenny together ate [tex]\frac{3}{8}[/tex]of the pizza. To determine if they ate the whole pizza, we need to add these fractions.

[tex]\frac{1}{8}[/tex] (Julie's portion) + [tex]\frac{3}{8}[/tex] (Ellen and Jenny's portion) =  [tex]\frac{4}{8}[/tex]or [tex]\frac{1}{2}[/tex] after simplifying.

Since [tex]\frac{1}{2}[/tex] is less than a whole, Julie, Ellen, and Jenny did not eat the entire pizza. They ate only half of it.

Answer:

x = [tex]\frac{20}{3}[/tex]

Step-by-step explanation:

ΔABC and ΔEDC are similar triangles ( AA ), hence the ratios of corresponding sides are equal, that is

[tex]\frac{AB}{ED}[/tex] = [tex]\frac{BC}{DC}[/tex], substitute values

[tex]\frac{x}{4}[/tex] = [tex]\frac{5}{3}[/tex] ( cross- multiply )

3x = 20 ( divide both sides by 3 )

x = [tex]\frac{20}{3}[/tex]

Answer: The identity is verified. See the explanation.

Step-by-step explanation:

You must keep on mind the following identities:

[tex]csc\theta=\frac{cos\theta}{sin\theta}\\\\csc\theta=\frac{1}{sin\theta}\\\\sin^2\theta+cos^2\theta=1[/tex]

Therefore, by substitution, you can rewrite the identity as shown below:

[tex]1+cot^2\theta=csc^2\theta\\\\1+\frac{cos^2\theta}{sin^2\theta}=csc^2\theta[/tex]

Simpliying, you obtain:

[tex]\frac{sin^2\theta+cos^2\theta}{sin^2\theta}=csc^2\theta\\\\\frac{1}{sin^2\theta}=csc^2\theta\\\\csc^2\theta=csc^2\theta[/tex]

The identity is verified.

y = 131

The area of the trapezoidal courtyard is 114 square meters.

To find the area of a trapezoid, you can use the formula:

[tex]\[ \text{Area} = \frac{1}{2} \times (\text{sum of the bases}) \times \text{height} \][/tex]

Given:

- Base 1 (b1) = 8 meters

- Base 2 (b2) = 11 meters

- Height (h) = 12 meters

Plugging these values into the formula:

[tex]\[ \text{Area} = \frac{1}{2} \times (8 + 11) \times 12 \][/tex]

[tex]\[ \text{Area} = \frac{1}{2} \times 19 \times 12 \][/tex]

[tex]\[ \text{Area} = \frac{1}{2} \times 228 \][/tex]

[tex]\[ \text{Area} = 114 \][/tex]

So, the area of the courtyard is 114 square meters.

Answer:

[tex]x=53[/tex]

Step-by-step explanation:

step 1

Find the measure of arc DF

we know that

The inscribed angle measures half that of the arc comprising

so

[tex]m<OEF=\frac{1}{2}(arc\ DF)[/tex]

we have

[tex]m<OEF=32\°[/tex]

substitute

[tex]32\°=\frac{1}{2}(arc\ DF)[/tex]

[tex]arc\ DF=64\°[/tex]

step 2

Find the measure of x

we know that

[tex]arc\ DF+arc\ EF=180\°[/tex] ---> is half the circle

we have

[tex]arc\ DF=64\°[/tex]

[tex]arc\ EF=(2x+10)\°[/tex]

substitute

[tex]64\°+(2x+10)\°=180\°[/tex]

[tex]2x\°=180\°-74\°[/tex]

[tex]2x\°=106\°[/tex]

[tex]x=53[/tex]

The value of x for the angles of the inscribed circle is gotten as; x = 53°

Let us first find the angle subtended by the arc DF

From inscribed angle theorem, we know that the measure of an inscribed angle is half the measure of the intercepted arc. Thus;

m∠EOF = ¹/₂(arc DF)

Thus;

¹/₂(arc DF) = 32°

arc DF = 64°

From half circle theorem, we can say that;

arc DF + arc EF = 180°

Thus;

64 + 2x + 10 = 180

2x = 180 - 74

2x = 106

x = 53°

Answer:

tn = 7 + (n - 1)*(-2) or

tn = 9 - 2n

Step-by-step explanation:

You are (beginning with 7) subtracting 2 from the term to the left.

a = 7

d = -2

tn = a1 + (n - 1)*d

tn = 7 + (n - 1)*(-2)

Try this out on n = 4

t4 = 7 + (4 - 1)*-2

t4 = 7 +  (3) (-2)

t4 = 7 - 6

t4 = 1 just as it says.

More generally

tn = 7 + (n - 1)*-2

tn = 7 + (-2n) + 2

tn = 9 - 2n

Answer:

* The degree of the function is 4 and the leading coefficient is positive

 f(x) = (x + 6)(2x - 3)(x - 1)²

* The degree of the function is 5 and the leading coefficient is negative

 f(x) = (x - 2)²(-2x - 1)²(-x + 1)

* The degree of the function is 6 and the leading coefficient is negative

 f(x) = (-x + 1)³(x + 2)²(x - 3)

* The degree of the function is 5 and the leading coefficient is positive

 f(x) = (-2x + 1)²(x - 3)²(x + 1)

Step-by-step explanation:

∵ f(x) = (x + 6)(2x - 3)(x - 1)²

∵  (x)(2x)(x²) = 2x^4

∴ The degree of the function is 4

∴ The leading coefficient is positive ⇒ (2)

∵ f(x) = (x - 2)²(-2x - 1)²(-x + 1)

∵ (x)²(-2x)²(-x) = (x²)(4x²)(-x) = -4x^5 ⇒ (neglect -ve with even power)

∴ The degree of the function is 5

∴ The leading coefficient is negative ⇒ (-4)

∵ f(x) = (-x + 1)³(x + 2)²(x - 3)

∵ (-x)³(x)²(x) = (-x³)(x²)(x) = -x^6

∴ The degree of the function is 6

∴ The leading coefficient is negative ⇒ (-1)

∵ f(x) = (-2x + 1)²(x - 3)²(x + 1)

∵ (-2x)²(x)²(x) = (4x²)(x²)(x) = 4x^5

∴ The degree of the function is 5

∴ The leading coefficient is positive ⇒ (4)
