Step-by-step explanation:

4. This angle is greater than a right angle (because it extends farther than one), so this is obtuse.

5. This angle is greater than a right angle, so this is obtuse.

6. This angle is smaller than a right angle (because it extends less than one), so this is acute.

7. This angle is smaller than a right angle, so this is acute.

8. This angle is greater than a right angle, so this is obtuse.

I need help on this please
Leya [2.2K]

The expression we have is:

2xy\cdot xy^2

And we are given some values for x and y:

\begin{gathered} x=2 \\ y=4 \end{gathered}

The first step will be to substitute the given values into the expression:

2(2)(4)\cdot(2)(4)^2

The next step is to solve 4^2 which is equal to 16:

2(2)(4)\cdot(2)(16)

And then we solve the multiplications, 2(2)(4) is equal to 16 and (2)(16) is equal to 32:

16\cdot32

Solving this final multiplication we get the result:

512

Answer: 512

A normal distribution has a mean of 4 and a standard deviation of 1. What percent of values are from 4 to 7?
Igoryamba

Answer:

49.865%

Step-by-step explanation:

Given that:

μ = 4 ; σ = 1

For x = 4

P(x < 4) :

Z score (x - μ) / σ

P(x < 7) - P(x < 4)

((7 - 4) / 1) - ((4 - 4) / 1)

P(Z < 3) - P(Z < 0)

Usibg the Z probability calculator :

0.99865 - 0.5

= 0.49865

= 0.49865 * 100

= 49.865%

Solve : t+2t squared
zloy xaker [14]

Answer:

t=0 or t=-1/2

Step-by-step explanation:

Solve for t over the real numbers:

t (2 t + 1) = 0

Split into two equations:

t = 0 or 2 t + 1 = 0

Subtract 1 from both sides:

t = 0 or 2 t = -1

Divide both sides by 2:

Answer: |

| t = 0 or t = -1/2
