Answer:

2 1/2

Step-by-step explanation:

The only way for the friends to get an equal amount is to split one of the cookies in half. or 5 divided by 2= 2 1/2

Answer:

$48

Step-by-step explanation:

Answer:

A.) No

B.) test statistic = - 3.108

Check explanation

Step-by-step explanation:

H0: m = 105 versus H1: m ≠ 105

Sample size, n = 35, since we have a large sample size, greater than 30.

B.)

xbar = 101.9 ; s = 5.9

Test statistic :

T = (xbar - μ) ÷ (s/√n)

T = (101.9 - 105) / (5.9/√35)

T = - 3.1 / 0.9972820

Test statistic = - 3.11

Pvalue from Tstatistic, df = 34

Pvalue = 0.003772( Pvalue calculator)

Pvalue is the probability of obtaining a value more extreme or exactly that of the test statistic.

At α = 0.01

Pvalue < α ; We fail to reject the Null

Answer: 21.4

Step-by-step explanation:

Area of a triangle = (1.7 * 2)/2=1.7 m2

Area of a rectangle = 3 * 2 = 6 m2

3 * 6 = 18 m2 2 * 1.7 = 3.4 m2

the total area is 18 + 3.4 = 21.4 m2

Answer:

Step-by-step explanation:

because the ratio of their corresponding sides are not equal.

Answer:

Vertical and supplementary

Step-by-step explanation:

Angles 1 and 2 are Vertically opposite angles and therefore they are equal to each other.

Answer: 192

Step-by-step explanation:

Answer:

Assuming the similarity is that BC scales to EF, answer is

D. 1.5BC

Step-by-step explanation:

Because the triangles are smilar, AB/BC = DE/EF

If AB = 2BC

then DE = 2EF

but also DE = 3BC

so 2EF = 3BC

EF = 1.5BC

Answer:

 [tex]M' =(-1,7)[/tex]

[tex]N' =(-1,-4)[/tex]

[tex]O' =(-4,4)[/tex]

[tex]P' =(-4,7)[/tex]

Step-by-step explanation:

Given

[tex]M = (-7, 1)[/tex]

[tex]N = (4, 1)[/tex]

[tex]0 = (-4, 4)[/tex]

[tex]P = (-7, 4)[/tex]

Line: [tex]y = -x[/tex]

Required

The coordinates of M'N'O'P'

The rule for reflection over [tex]y=-x[/tex] is : [tex](x,y) \to (-y,-x)[/tex]

So, we have:

[tex]M = (-7, 1)[/tex]  [tex]\to M' =(-1,7)[/tex]

[tex]N = (4, 1)[/tex] [tex]\to N' =(-1,-4)[/tex]

[tex]0 = (-4, 4)[/tex] [tex]\to O' =(-4,4)[/tex]

[tex]P = (-7, 4)[/tex] [tex]\to P' =(-4,7)[/tex]

So, the points are:

[tex]M' =(-1,7)[/tex]

[tex]N' =(-1,-4)[/tex]

[tex]O' =(-4,4)[/tex]

[tex]P' =(-4,7)[/tex]

Answer:

97.27 yd²

Step-by-step explanation:

First let's find the area of the right triangle on the left side. To do that, multiply 6x5, then divide the product by 2, since a right triangle is half a rectangle.

6x5=30

30/2=15

Area of triangle=15 yd²

Find area of the middle rectangle. So multiply the length by the width.

9x6=54

Area of rectangle=54 yd²

Find area of the half circle. Formula for area of circle is [tex]A=\pi r^{2}[/tex]. Pi is about 3.14, and radius ([tex]r[/tex]) is 3. Radius is half of the diameter of circle, and the 6 on the left says the diameter of circle.

[tex]\pi[/tex]x[tex]3^{2}[/tex]≈28.27

Area of circle is about 28.27 yd²

Add up the three areas.

15+54+28.27=97.27

Answer: d=sqrt(13)=3.605

Step-by-step explanation:

We know that the distance between the two points (x 1  ,y 1 ) and (x2,y  2 ) is

d= sqrt((x2-x1)^2 +(y2-y1)^2 )

as given

x1=-1 ,y=4 ,x2=-3,y2=7

d=sqrt((-3+1)^2+ (7-4)^2)

d=sqrt((-2)^2+(3)^2)

d=sqrt(4+9)

d=sqrt(13)=3.605

Answer:

x = 2.2y

Step-by-step explanation:

Given that,

1 kg = 2.2 pounds

We know that, the relation between kg and pounds is given by :

1 kg = 2.2 pounds

The variation equation can be given by :

Let x denotes kg and y denotes pounds.

So,

x = 2.2y

Hence, the variation is x = 2.2y.

Answer:

A should be 2

B should be -2/5
