Answer:

518 cm squared

Step-by-step explanation:

Answer:

518 cm²

Step-by-step explanation:

First, we can split the shape into two parts.

The first part will be 8+22(which is the width)x13(29-16, which is the height). This gives us:

30x13=390 cm²

Now, for the next part, we have 8(width)x16(height), which gives us:

8x16=128 cm²

Finally, we add 128+390=518cm²

Answers

Answer:

hello your question is incomplete below is the complete question

answer : 18%

Step-by-step explanation:

x = percentage using illicit drugs

sample size = 5000

number of persons with a yes = 1200

also management knows that 30% uses carpool

∴P ( yes ) = P( H and yes to carpool ) + P( T and yes to illicit drug use )

1200 / 5000 = (0.5 * 0.3 ) + ( 0.5 * x )

0.24 = 0.15 + 0.5 x

hence x ( percentage using illicit drug ) = ( 0.24 - 0.15) / 0.5 = 0.18 = 18%

What equation is represented by this graph?

Answers

Answer:

y= 1.2x+1

Step-by-step explanation:

(0,1) and (-5,-5) are coordinates that you already know and are fs about. So you just see rise over run. 6/5 = 1.2 which is your slope. the y-int is 1 bc thats where it intersects. so your equation is y=1.2x+1

double check:

y = 1.2(-5) + 1

y = -6 + 1

y = -5

coordinates : (-5,-5)

A. 72 m²
B. 144 m2
C. 288 m
D. 576 m

Answers

Answer:

Area of the actual room = 288 m²

Step-by-step explanation:

Given:

Scale factor = 2cm to 4 m

Dimension of rectangle ball room = 6 cm and 12 cm

Find:

Area of the actual room

Computation:

Actual dimension of rectangle ball room;

⇒ [6/2]4 = 12 m

⇒ [12/2]4 = 24 m

Area of rectangle = Length x Width

⇒ Area of the actual room = Actual length x Actual width

⇒ Area of the actual room = 12 x 24

Area of the actual room = 288 m²

Answers

Answer:

By Pythagoras theorem

x² = 7² + 14²

x² = 49 + 196

x² = 245

X = square root of 245

245 is number that belongs to the green box

The missing side of the right triangle is √245. The number that belongs in the green box is 245

Calculating the side length of a triangle

From the question, we are to determine the missing side of the given triangle

The missing side of the triangle can be determined by using Pythagoras' theorem

The theorem states that, in a right angle triangle

c² = a² + b²

Where c is the length of the longest side (hypotenuse)

and a & b are the other two sides

From the given information,

Hyp = x;

Let a = 7 and b = 14

∴ x² = 7² + 14²

x² = 49 + 196

x² = 245

x = √245

Heence, the missing side of the right triangle is √245. The number that belongs in the green box is 245.

Answer:

H1 : σ² ≠ 10

X² = 20.124

Pvalue = 0.064776

there is significant evidence to conclude that the rebound lengtb of rockfall down a slope is not 10m²

Step-by-step explanation:

Given the data:

10.94 13.71 11.38 7.26 17.83 11.92 11.87 5.44 13.35 4.90 5.85 5.10 6.77

Using a calculator ;

The sample variance, s² = 16.77

α = 0.10

The null and alternative hypothesis :

H0 : σ² = 10

H1 : σ² ≠ 10

The test statistic :

X² = [(n - 1)*s² ÷ σ²]

s² = 16.77

n = sample size = 13 ; s²

X² = [(13 -1)*16.77 ÷ 10

X² = (12 * 16.77) / 10

X² = 201.24 / 10

X² = 20.124

The Pvalue using a Pvalue calculator ; degree of freedom (df) = 13 - 1 = 12

Pvalue = 0.064776

Pvalue < α ; Hence we reject the null

Hence, there is significant evidence to conclude that the rebound lengtb of rockfall down a slope is not 10m²

Answers

This question is incomplete, the complete question is;

You are in a 12-member panel. If two people from the panel are selected to represent the panel, what is the probability you wont be selected.

[ Two decimal places ]

Answer:

The probability that you be selected is 0.83

Step-by-step explanation:

Given the data in the question;

total number of people in the panel = 12

number of people to be selected from the panel = 2

probability you wont be selected = ?

Number of ways of selecting 2 people from the 12 member panel is;

⇒ ¹²C₂ = 12! / ( 2!( 12 - 2 )! ) = 479001600 / 7257600 = 66

so total number of outcome = 66

Now, number of ways in favor of selecting you and another person from the 12 member panel is;

⇒ ¹C₁ × ¹¹C₁ = [1! / ( 1!( 1 - 1 )! )] × [11! / ( 1!( 11 - 1 )! )] = 1 × 11 = 11

so favorable number of outcome = 11

∴ Probability of selecting you in the panel will be;

⇒ favorable number of outcome / total number of outcome

⇒ 11 / 66 = 1/6

Now, Probability of not selecting you in the panel will be;

⇒ 1 - Probability of selecting you in the panel

⇒ 1 - 1/6

⇒ 0.83

Therefore, The probability that you be selected is 0.83

Step-by-step explanation:

The subject chosen as a favorite by exactly 20% of the students is maths.

What is a percentage?

The percentage means the required value out of 100.

It is calculated by dividing the required value by the total value and multiplying it by 100.

The percentage change is also calculated using the same method.

In percentage change, we find the difference between the values given.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

From the circle graph,

Maths = 20%

English = 25%

Hindi = 10%

Science = 45%

We see that,

The subject was chosen as a favorite by exactly 20% of the students in maths.

Thus,

The subject was chosen as a favorite by exactly 20% of the students in maths.
