The rectangle ABCD is reflected across the y-axis. What are the
coordinates of the vertex A'?

Answer:

No ;

Step-by-step explanation:

Given ;

s2 = 10 ; n2 = 10 ; s1 = 12 ; n1 = 12

Hypothesis :

H0 : σ1² = σ2²

H1 : σ1² ≠ σ2²

The test statistic :

Ftest = s1² / s2² = 12² / 10² = 144 / 100 = 1.44

The Pvalue using the Pvalue from Ftest calculator :

Numerator df = 12 - 1 = 11

Denominator df = 10 - 1 = 9

Pvalue = 0.2969

At α = 0.1

If Pvalue > α ; Fail to reject H0

0.2969 > 0.1 ; Hence, we fail to reject the Null

Hence, we cannot conclude that variation exists

The line plot shows the weights of packages of meat that members of a club bought. The meat will be mixed with vegetables to make stew for a club dinner. Each serving of the stew contains 1/4 pound of meat. How many servings of the stew can the club make?

Answer:

36 servings

Step-by-step explanation:

From the plot ; we take the sum of total weight of meat packages :

(5/8 * 2) + 6/8 + 1 + (9/8 * 3) + 10/8 + 11/8

10/8 + 6/8 + 8/8 + 27/8 + 10/8 + 11/8 = 72 / 8 = 9 meat packages

Each serving of meat = 1/4

Number of servings the club can make :

Total meat package / pound of meat per serving

(9 ÷ 1/4)

9 * 4/1

= 36 servings

36 hope this help

Answer:

1 ladrillo cuesta 1 dólar.    1 brick costs 1 dollars.

1 kg de cemento cuesta 3 dólares: 1 kg cement costs 3 dollars

1 kg de arena cuesta $ 16: 1 kg sand costs $ 16

Step-by-step explanation:

Spanish

Deje que los ladrillos, la arena y el cemento se denoten por b, sy c. Luego, de acuerdo con la condición dada

20b + 5s + 10c = $ 130 --- ecuación 1

1c = 3b ------ ecuación 2

1s = 4c + 4b ------ ecuación 3

Poniendo la ecuación 2 en la ecuación 3

1s = 4 (3b) + 4b

1s = 16b ---------- ecuación 4

20b + 5s + 10 (3b) = $ 130

50b + 5s = 130 --- ecuación 5

Poniendo la ecuación 4 en la ecuación 5

50 b + 5 (16b) = 130

50 b + 80b = 130

130 b = 130

b = 130/130 = $ 1 ------- ecuación a

1 ladrillo cuesta 1 dólar.

Poner el valor de costo de 1 ladrillo en estas ecuaciones

1c = 3b ------ ecuación 2

1s = 4c + 4b ------ ecuación 3

1c = 3 (1) = $ 3 -------- ecuación b

1 kg de cemento cuesta 3 dólares

1s = 4c + 4b

1 s = 4 (3) + 4 (1)

1 s = 12 + 4

1s = $ 16 ------ ecuación c

1 kg de arena cuesta $ 16

Poner valores de la ecuación a, b, c en la ecuación 1

20b + 5s + 10c = $ 130

20 (1) + 5 (16) + 10 (3) = 130

20 + 80 + 30 = 130

130 = 130 ------------ por lo tanto probado

English

Let the bricks , sand and cement be denoted by b, s and c. Then according to the given condition

20b+ 5s+ 10c= $130--- equation 1

1c= 3b------ equation 2

1s= 4c+4b------ equation 3

Putting equation 2 in equation 3

1s= 4(3b) + 4b

1s= 16b---------- equation 4

20b+ 5s+ 10(3b)= $130

50b + 5s= 130--- equation 5

Putting equation 4 in equation 5

50 b + 5 (16b) = 130

50 b+ 80b= 130

130 b= 130

b= 130/130= $1------- equation a

1 brick costs 1 dollars.

Putting the cost value of 1 brick in these equations

1c= 3b------ equation 2

1s= 4c+4b------ equation 3

1c= 3(1)= $3-------- equation b

1 kg cement costs 3 dollars

1s= 4c+4b

1s= 4(3) + 4(1)

1s= 12+4

1s= $16 ------ equation c

1 kg sand costs $ 16

Putting values from equation a, b, c in equation 1

20b+ 5s+ 10c= $130

20 (1) + 5 (16) + 10 (3)= 130

20 + 80 + 30 = 130

130 = 130   ------------ hence proved

Answer:

I'm sorry im not sure :-(

Step-by-step explanation:

The decimal is a repeating decimal, and the actual fraction represented by 0.64⁻ is 64/99

The decimal number is given as:

0.64⁻

There are two numbers after the decimal point

So, the number of repeating digits is 2

In (a), we have the number of repeating digits to be 2.

So, the value multiplied on both sides is:

Value = 10²

Value = 100

Hence, the value multiplied on both sides of the equals sign is 100

The number is the decimal points is 64.

And the value multiplied on both sides of the equals sign is 100.

So, the fraction is:

64/(100 - 1)

This gives

64/99

Hence, the actual fraction represented by 0.64⁻ is 64/99

Answer:

Step-by-step explanation:

Find the area of the larger rectangle first, and then minus the area of the smaller rectangle.

The length of the larger rectangle

= 9-3 = 6 in

The width of the larger rectangle

= 17-1 = 16 in

The area of the larger rectangle

= 6×16

= 96 in²

The length of the smaller rectangle

= 8-4 = 4 in

The width of the smaller rectangle

= 13-5 = 8 in

The area of the smaller rectangle

= 4×8

= 32 in²

The area of the picture frame

= 96-32

= 64 in²
