Answer:

Area of larger circle = $\pi *r^2=3.14(11^2)=379.94$

Area of smaller circle = $\pi *r^2=3.14(3^2)=28.26$

Probability that it lands in the shaded area (smaller circle):

28.26 ÷ 379.94 = 0.07438... = 0.07 (nearest hundredth)

A computer is generating passwords. The computer generates ten characters at random, and each is equally likely to be any of the

7nadin3 [17]

Answer: 0.0386

Step-by-step explanation:

Number of digits = 10

Number of letters in English alphabet = 26

Total number of characters = $10+26=36$

Now, if replication is allowed, then the total number of ways to make a ten character password will be :_

$(36)^{10}$

The number of ways to make a password having all letters :-

$(26)^{10}$

Now, the probability that the password will contain all letters will be :-

$\dfrac{26^{10}}{36^{10}}=0.0386107708316\approx0.0386$

Hence, the probability that the password will contain all letters =0.0386

I need help with answering question 16 on spring board algebra 2 pg. 35 the questions says solve the system using substitution t

Jet001 [13]

Answer:

x = 147

y = 32

Step-by-step explanation:

I got a bit confused by what you said, but I think you need help being shown how to do 16, so hopefully the following will help!

So to use substitution you "plug in" the expression into each other. Here is what to do for 16!

[] First, we need to find which expression can be plugged in. The first one works! It is set equal to x, so we can easily plug it in.

[] Now, we need to set up our equation!

3y - x = -13

/\

4y + 19 = x

3y - 4y + 19 = -13

[] Now, we solve for y and simplfy!

3y - 4y + 19 = -13

-y = -32

(I subtracted 19 for both sides and combined the y's)

Now I am going to add -y and -32 to both sides so I can have it be positive.

y = 32

[] Last, but not least, we solve for x!

- Plug the y you just solved into the equation for x

4y + 19 = x

4(32) + 19 = x

128 + 19 = x

147 = x

(hopefully this is correct, have a nice day!)

Daredevil Danny was cliff jumping. He jumped off a cliff that was 1 4 . 2 14.214, point, 2 meters above the surface of the water

iragen [17]

Question:

Daredevil Danny was cliff jumping. He jumped off a cliff that was 14.2 meters above the surface of the water. At the end of his jump, Danny was 2.3 meters below the surface of the water.

The following equation describes this situation 14.2 + (-16,5) = -2.3 .

What does -16.5 tell us?

Answer:

The displacement between his current position and his initial position

Step-by-step explanation:

Given

$Initial\ Position = 14.2m$

$Final\ Position = -2.3m$

$14.2 + (-16.5) = -2.3$

Required

What does -16.5 represents?

To understand this, we need to first calculate the displacement between his initial and final position

$Displacement = Final\ Position - Initial\ Position$

$Displacement = -2.3m - 14.2m$

$Displacement = - 16.5m$

So: -16.5m is the total displacement from the start position (i.e. off the cliff) and current position (beneath the water surface)
