The marks on the number line are used to represent the points on the number line

The point on the given diagram is on the point x = -1

The value of x is given as:

x = -1

The above equation means that, the value of x is on the -1 point of x

This in other words means that, the position of x is 1 point to the left of 0

From the diagram, the point is already on the point x = -1

Answer:

p = 33/100 = 33%

Step-by-step explanation:

p (probability) = 1.00 - [variables]

p = 1.00 - (0.12 + 0.07 + 0.05 + 0.28 + 0.15)

p = 1.00 - 0.67

p = 33/100

Answer:

37 yd²

Step-by-step explanation:

The computation of the surface area of this triangular pyramid is shown below:

The surface area of this triangular pyramid  is

But before that

Lateral area = 3(1 ÷ 2) × base × height

= (3 ÷ 2)(4 yd)(5 yd)

= 30 yd²

Now

base area = 1 ÷ 2 × base × height

= 1 ÷ 2(4 yd)(3.5 yd)

= 7 yd²

Now the total surface area is  

surface area = lateral area + base area

= 30 yd² + 7 yd²

= 37 yd²

The volume of the triangular prism = [tex]V = (base-area)*height[/tex]

Thus the volume is [tex]\\V = (\frac{1}{2} *3*4) * 7 = 6 * 7 = 42[/tex].

Thus the volume is 42 cubic km.

Answer:

220°

Step-by-step explanation:

[tex]\angle PQM [/tex] is inscribed in the [tex]\widehat{PQM}[/tex] and [tex]\widehat{PNM}[/tex] is intercepted by it.

Therefore, by inscribed angle theorem:

[tex]m\angle PQM =\frac{1}{2}\times m\widehat{(PNM)}[/tex]

[tex]\implies 110\degree =\frac{1}{2}\times m\widehat{(PNM)}[/tex]

[tex]\implies 110\degree \times 2= m\widehat{(PNM)}[/tex]

[tex]\implies m\widehat{(PNM)}= 220\degree [/tex]

x/3=how much the tickets cost

Step-by-step explanation:

If each of the four friends pays $7.04, the equation would be set up like this: 7.04*4=28.16. This means the total cost for tickets is 28.16. If the total cost for three tickets is 28.16, just divide the total cost by how many tickets were purchased. 28.16/3=9.39. This means one ticket cost 9.39.

[tex]\longrightarrow \sf £ \:9.4 [/tex]

[tex]\leadsto[/tex]Money paid by 1 friend = £ 7.05

[tex]\leadsto[/tex]Money paid by 4 friend = £ 7.05 × 4

[tex] \quad\quad\quad\quad\quad\quad\quad\quad\quad\quad[/tex]= £ 28.2

This is equal to cost of 3 tickets

[tex]\leadsto[/tex] Cost of 3 tickets = £ 28.2

[tex]\leadsto[/tex] Cost of 1 ticket = £ 28.2 ÷ 3

[tex]\quad\quad\quad\quad\quad\quad\quad\quad\quad[/tex]=£ 9.4

Thus , each ticket cost £ 9.4 .

Step-by-step explanation:

Given : AD=4 cm,DB=(x−4) cm,AE=8 cm and EC=(3x−19) cm.  

To Find : x

We know that, by BPT(Basic proportionality theorem)

DBAD=ECAE 

(x−4)4=(3x−19)8

4(3x−19)=8(x−4) 

12x−76=8x−32

D)  [tex]x=\frac{5}{3}[/tex] and [tex]x=-4[/tex]

Step-by-step explanation:

Factor by grouping

[tex]3x^2+7x-20=0\\\\3x^2+12x-5x-20=0\\\\3x(x+4)-5(x+4)=0\\\\(3x-5)(x+4)=0[/tex]

Solve each factor using the Zero Product Property

[tex]3x-5=0\\\\3x=5\\\\x=\frac{5}{3}[/tex]

[tex]x+4=0\\\\x=-4[/tex]

Thus, [tex]x=\frac{5}{3}[/tex] and [tex]x=-4[/tex] are the solutions

Answer:

A. 16.86 square inches

Step-by-step explanation:

Area of Circle = [tex]\pi r^2[/tex], where r = radius.

Area of Rectangle = [tex]l * w[/tex], where l = length and w = width.

We are given the radius of the circle as 1, and we use π as 3.14

Next, we find the area of the rectangle.

Lastly, we subtract 3.14 from 20.

Therefore, the answer is A. 16.86 square inches.

Answer:

16.86

Step-by-step explanation:

The circle area =3.14*1=3.14

The area of the square- the circle=shaded area.

=20-3.14=16.86

The probability of randomly selected students who will be absent no more than one day is 0.92. Option D is correct.

The probability is defined as the number of favorable occurrences of an event.

Given the probability distribution of the number of absence for one week,

x:            0         1         2         3       4      5

P(X):    0.78    0.14    0.03    0.01    0    0.04

We know that the probability of any event is always less than equal to 1. We can write that,  [tex]P(x\leq 1)[/tex].

So the probability of randomly selected students who will be absent no more than one day is calculated as given below.

[tex]P = P (x=0) + P(x=1)\\P = 0.78 + 0.14[/tex]

[tex]P = 0.92[/tex]

Hence we can conclude that the probability of randomly selected students who will be absent no more than one day is 0.92. Option D is correct.
