Answer:

a.It has both line symmetry and rotational symmetry.

Step-by-step explanation:

The line symmetry is another name for reflection symmetry, where if you fold the image to get two half figures, both the halves will be exactly same. First half is the reflection of the other half.

A shape is said to have rotational symmetry, when it looks the same after being rotated.

The given figure has both symmetries.

So, the correct answer for given figure is - It has both line symmetry and rotational symmetry.

Neko [114]

Answer:

The correct answer is option (C)-0.245 = 2.160(0.205)

Step-by-step explanation:

Solution

Given that:

The slope = - 0.245

The size sample = n = 15

The standard error = 0.205

The confidence level = 95

The Significance level= α = (100- 95)% = 0.05

Now,

The freedom of degree = n-2 = 15 -2= 13

Thus,

the critical value = t* = 2.16

By applying Excel = [TINV (0.05, 13)]

The Margin of error is = t* (standard error)

=2.16 *0.205

= 0.4428

denpristay [2]

Answer:

w = 12

Step-by-step explanation:

W=48/4

W=12 ANS. FOR THE WIDTH.

L=12+8=20 ANS. FOR THE LENGTH.

PROOF:

2*20+2*12=64

40+24=64

64=64

Noah drew 22 hearts and 76 circles. What is the ratio of circles to all the shapes?

dimulka [17.4K]

You would make a fraction with circles on the top which would be 76. Then you would add 22 to 76 and get 97 because that is the number of all of the shapes. That would mean your fraction would be 76/97. If u want to simplify that is up to you.
