Answer: 6
Step-by-step explanation: as we already know, 45 is half of 90. So that means he is mowing 2 lawns in an hour. So in 6 hours he mows twice the amount.
the kind(s) of symmetry. (Select all that apply.) F point line plane none is given below
Step-by-step explanation:
- The four main types of this symmetry are translation, rotation, reflection, and glide reflection.
- There are three basic types of symmetry: reflection symmetry, rotational symmetry, and point symmetry.
- Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror like reflection of either side of the object. ... Symmetry is a key concept in geometry which cuts the figure into two halves that are exact reflections of each other, as shown in figure given below.
- Symmetry is something that we observe in many places in our daily lives without even noticing it. It is easily noticeable in various arts, buildings, and monuments. Nature uses symmetry to make things beautiful. For example, consider the pictures of the butterfly and the leaf .
- Use symmetry in a sentence. noun. Symmetry is an attribute where something is the same on both sides of an axis. An example of symmetry is a circle that is the same on both sides if you fold it along its diameter.
Answer:
.173 seconds or a negataive
Step-by-step explanation:
Your formula would be
h = -16t^2 - 55t + 10
when it hits the ground h = 0
16t^2 + 55t - 10 = 0
t = (-55 ± √3665)/32 = .173 seconds or a negataive
Answer:
C. The president rejects the hypothesis that the proportion of students who earn a bachelor's degree within six years is 0.398, when, in fact, the proportion is 0.398.
Step-by-step explanation:
A type I error occurs if you reject the null hypothesis when it is true.
Now the hypotheses are:

The proportion is 0.398

The proportion is less than 0.398
If in actual fact the proportion is 0.398, then the president must not reject the

.
This is a correct decision.
If in actual fact the proportion is 0.398, and the president rejects the

, then a type I error is committed.
The correct choice is C.
It would be doubled i think actually no just do the same equation with 4. i need to see the question first
