Answer:

Segment EH and segment E prime H prime both pass through the center of dilation (A)

The complete question related to this found on brainly (ID:16812154) is stated below:

E(0,5) F(1,1) G(-2,1) H(0,1)

a) segment EH and segment E prime H prime both pass through the center of dilation.

b)The slope of segment EF is the same as the slope of segment E prime H prime.

c) segment E prime G prime will overlap segment EG. segment

d) EH ≅ segment E prime H prime.

There are 11 that contain equal numbers of toy cars and 6 that contain equal number of helicopter toy.

<h3>Greatest common factor</h3>

John is filling in party goodie bags with toy cars and helicopters. There are 66 toy cars and 36 helicopters. Each bag must only have either toy car or helicopter - there is no mixing of toys.

Each bag must have the same number of toy cars in it.

Each bag must have the same number of toy helicopter in it.

All bags must have the same number of toys in it.

a) How many bags will contain toy cars?

b) How many bags will contain toy helicopters?

Factors of 66: 1, 2, 3, 6, 11, 22, 33, and 66.

Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, and 36

The greatest common factor of 66 and 36 it s 6

66 ÷ 6 = 11 toy cars

36 ÷ 6 = 6 helicopter toy

Therefore, there are 11 that contain equal numbers of toy cars and 6 that contain equal number of helicopter toy.

An employer wishes to compare typing speeds of graduates from 2 different study programs: A and B. Eight random graduates from c

Karolina [17]

Answer:

Calculated value t = 0.614< 1.782

we accepted null hypothesis for 12 degrees of freedom at 0.05 level of significance .

Step-by-step explanation:

we will t-test t = x⁻- y⁻ /S√ n₁+n₂-2

Given An employer wishes to compare typing speeds of graduates from 2 different study programs: A and B

course A type at 62, 85, 59, 64, 73, 70, 75, and 72

mean of x is x⁻ = ∑x / n

mean of x = 62+85+59+64+73+70+75+ 72 /8 = 70

x⁻ = 70

course B type at 75, 64, 81, 55, 69, and 58

mean of y is y⁻ = ∑y / n = 75+64+81+55+69+ 58/6 = 67

y⁻ =67

course A course B

x y x- x⁻ (x-x⁻ )^2 y- y⁻ (y-y⁻ )^2

62 75 8 64 8 64

85 64 15 225 -3 9

59 81 -11 121 14 196

64 55 -6 36 -12 144

73 69 3 9 2 4

70 58 0 0 -9 81

75 5 25

72 2 4

∑( (x-x⁻ )^2= 484 ∑( (y-y⁻ )^2= 498

Adding ∑( (x-x⁻ )^2+ ∑( (y-y⁻ )^2= 982

n₁+n₂-2 = 8+6-2=12

now S^2 = 982/ 12 =81.833

Null hypothesis :H₀:μ₁=μ₂ ( there is no difference between A and B)

Alternative hypothesis :H₁:μ₁≠μ₂

level of significance ∝=0.05

we will use t-test t = 0.614 ( see attachment )

The degrees of freedom = n₁+n₂-2 = 8+6-2=12

From tabulated value t = 1.782

Calculated value t = 0.614< 1.782

we accepted null hypothesis for 12 degrees of freedom at 0.05 level of significance .

There is no difference between Course A and Course B

Cheryl is buying lace for her dance costume. One foot of lace costs 3 dollars. How much does each amount cost?

NemiM [27]

Answer:

3/4 of a foot will cost $2.25.

Step-by-step explanation:

This question is solved by rule of three, due to proportions.

One foot of lace costs 3 dollars. How much is 3/4 of a foot going to cost?

1 foot - 3 dollars

3/4 foot - x dollars

$x = 3 \times \frac{3}{4} = \frac{9}{4} = 2.25$

3/4 of a foot will cost $2.25.
